Paul Krugman, NYT Magazine: Can Europe Be Saved? The United States works as a currency union in large part precisely because it is also a transfer union, in which states that haven’t gone bust support those that have. And it’s hard to see how the euro can work unless Europe finds a way to accomplish something similar. Nobody is yet proposing that Europe move to anything resembling U.S. fiscal integration; the Juncker-Tremonti plan would be at best a small step in that direction. But Europe doesn’t seem ready to take even that modest step. In any case, the odds are that the current tough-it-out strategy won’t work even in the narrow sense of avoiding default and devaluation — and the fact that it won’t work will become obvious sooner rather than later. At that point, Europe’s stronger nations will have to make a choice.

Andrew Leonard, Salon: Alan Greenspan's housing bubble coffee break. On Friday, the Federal Reserve released the transcripts of its 2005 Open Market Committee meetings -- the gatherings in which the Fed's Board of Governors takes the pulse of the economy and then decides upon the appropriate interest rate policy. The warning signs were written in blazing Day-Glo orange on the Fed temple walls. Greenspan ignored them, and the U.S. economy hurtled directly into the worst economic disaster since the Great Depression.

Adam Ozimek, Modeled Behavior: Why do forecasters have such disagreement? One might expect that over time economic forecasters should converge in methodologies, and thus in forecasts, as the competitive market for forecasters creates a natural selection that weeds out unsuccessful strategies and pushes forecasters towards the most successful strategy. However there is still a wide divergence in economic forecasts, which begs the question what part of that natural selection is failing? ….A third, and I believe most important, explanation is the failure of the  assumption that the competitive market for forecasters creates incentives to have the most accurate forecasts possible. A great example of the lack of a direct relationship between accuracy and incentives is Nouriel Roubini.

Joseph W. Gruber, Steven B. Kamin, Fed: Fiscal Positions and Government Bond Yields in OECD Countries. We examine the impact of fiscal positions, both the level of debt and the fiscal balance, on long-term government bond yields in the OECD. In order to control for the endogenity of fiscal positions to the business cycle we utilize forward projections of fiscal positions from the OECD’s Economic Outlook. In a panel regression over the period from 1988 to 2007, we find a robust and significant effect of fiscal performance on long-term bond yields. Our estimates imply that the marginal effect of the projected deterioration of fiscal positions associated with the recent financial crisis is to add about 60 basis points to U.S. bond yields by 2015, with effects on other G7 bond yields generally being smaller.

Anna Iara, Guntram Wolff, VoxEU: Sovereign risk: The impact of national numerical fiscal rules. The Eurozone crisis has whetted the appetite for economic governance reform in the EU, with one high-profile proposal aiming to strengthen national fiscal frameworks. With a unique data set, this column shows that stronger fiscal rules in Eurozone member states reduce sovereign risk, especially in times of high uncertainty. If followed, these rules could reduce sovereign yield spreads by up to 100 basis points.

Maurizio Michael Habib, Livio Stracca, ECB: Getting Beyond Carry Trade. What Makes A Safe Haven Currency?  The main objective of this paper is to find out what the fundamentals of safe haven currencies are. We analyse a large panel of 52 currencies in advanced and emerging countries over almost 25 years of data. We find that only a few factors are robustly associated to a safe haven status, most notably the net foreign asset position, an indicator of external vulnerability, and to a lesser extent the absolute size of the stock market, an indicator of market size and development. The interest rate spread against the US is significant only for advanced countries, whose currencies are subject to carry trade. More generally, we find that it is hard to predict what currencies would do when global risk aversion is high, as estimates are imprecise and often not stable or robust. This suggests caution in over-interpreting exchange rate movements during financial crises.

Gadi Barlevy, Jonas D.M. Fisher, Chicago Fed: Mortgage Choices and Housing Speculation. We describe a rational expectations model in which speculative bubbles in house prices can emerge. Within this model both speculators and their lenders use interest-only mortgages (IOs) rather than traditional mortgages when there is a bubble. Absent a bubble, there is no tendency for IOs to be used. These insights are used to assess the extent to which house prices in US cities were driven by speculative bubbles over the period 2000-2008. We find that IOs were used sparingly in cities where elastic housing supply precludes speculation from arising. In cities with inelastic supply, where speculation is possible, there was heavy use of IOs, but only in cities that had boom-bust cycles. Peak IO usage predicts rapid appreciations that cannot be explained by standard correlates and this variable is more robustly correlated with rapid appreciations than other mortgage characteristics, including sub-prime, securitization and leverage. Where IOs were popular, their use does not appear to have been a response to houses becoming more expensive. Indeed, their use anticipated future appreciation.

Atif Mian, Amir Sufi, San Francisco Fed: Household Debt and the Weak U.S. Economy. The U.S. economic recovery has been weak, especially in employment growth. A microeconomic analysis of U.S. counties shows that this weakness is closely related to elevated levels of household debt accumulated during the housing boom. Counties where household debt grew moderately from 2002 to 2006 have seen a moderation of employment losses and a robust recovery in durable consumption and residential investment. By contrast, counties that experienced large increases in household debt during the boom have been mired in a severe recessionary environment even after the official end of the recession.

Sam Schulhofer-Wohl, Minneapolis Fed: Negative Equity Does Not Reduce Homeowners' Mobility. Some commentators have argued that the housing crisis may harm labor markets because homeowners who owe more than their homes are worth are less likely to move to places that have productive job opportunities. I show that, in the available data, negative equity does not make homeowners less mobile. In fact, homeowners who have negative equity are slightly more likely to move than homeowners who have positive equity.

James M. Sallee, Joel Slemrod, NBER:  Car Notches: Strategic Automaker Responses to Fuel Economy Policy. Notches --- where small changes in behavior lead to large changes in a tax or subsidy --- figure prominently in many policies, but have been rarely examined by economists. In this paper, we analyze a class of notches associated with policies aimed at improving vehicle fuel economy. We provide several pieces of evidence showing that automakers respond to notches in fuel economy policy by precisely manipulating fuel economy ratings so as to just qualify for more favorable treatment. We then describe the welfare consequences of this behavior and derive a welfare summary statistic applicable to many contexts.

Free exchange Blog: The value of college. So, do colleges actually teach students anything? A new book tracking 2,300 students at four-year universities includes some striking findings: 45 percent of students "did not demonstrate any significant improvement in learning" during the first two years of college. 36 percent of students "did not demonstrate any significant improvement in learning" over four years of college. Those students who do show improvements tend to show only modest improvements. Students improved on average only 0.18 standard deviations over the first two years of college and 0.47 over four years. What this means is that a student who entered college in the 50th percentile of students in his or her cohort would move up to the 68th percentile four years later -- but that's the 68th percentile of a new group of freshmen who haven't experienced any college learning.

Jérôme Adda, Anders Björklund, Helena Holmlund, IZA: The Role of Mothers and Fathers in Providing Skills: Evidence from Parental Deaths. We exploit a large administrative data set covering many Swedish cohorts. We develop new estimation methods to tackle the potential endogeneity of death at an early age, based on the idea that the amount of endogeneity is constant or decreasing during childhood. Our method also allows us to identify a set of death causes that are conditionally exogenous. We find that the loss of either a father or a mother on boys' earnings is no higher than 6-7 percent and slightly lower for girls. Our examination of the impact on cognitive skills (IQ and educational attainment) and on noncognitive skills (emotional stability, social skills) shows rather small effects on each type of skill. We find that both mothers and fathers are important, but mothers are somewhat more important for cognitive skills and fathers for noncognitive ones.

Edward L. Glaeser, Boston Globe: A lesson for America. Education may be the best way to reduce future unemployment. Anyone who worries about American decline must recognize that skills drive Asian economic success. In December, we learned that children in Shanghai were massively outperforming Americans on standardized tests, and President Obama understandably called for a new “Sputnik moment,’’ when America would again invest massively in its children. Now he must ensure that his party puts students ahead of teachers unions.

James D. Hamilton, UCLA: Historical Oil Shocks. As noted in the previous sections, these historical episodes were often followed by economic recessions in the United States. The last column of Table 1 reports the starting date of U.S. recessions as determined by the National Bureau of Economic Research. All but one of the 11 postwar recessions were associated with an increase in the price of oil, the single exception being the recession of 1960. Likewise, all but one of the 12 oil price episodes listed in Table 1 were accompanied by U.S. recessions, the single exception being the 2003 oil price increase associated with the Venezuelan unrest and second Persian Gulf War.

Daniel A. Hartley, Cleveland Fed:  Blowing it Up and Knocking it Down: The Effect of Demolishing High Concentration Public Housing on Crime. In Chicago, which has conducted the largest public housing demolition program in the United States, I find that public housing demolitions are associated with a 10 percent to 20 percent reduction in murder, assault, and robbery in neighborhoods where the demolitions occurred. Furthermore, violent crime rates fell by about the same amount in neighborhoods that received the most displaced public housing households relative to neighborhoods that received fewer displaced public housing households, during the period when these developments were being demolished. This suggests violent crime was not simply displaced from the neighborhoods where demolitions occurred to neighborhoods that received the
former public housing residents.

St. Claire, L., Hayward, R., and Rogers, P. Interactive Effects of Caffeine Consumption and Stressful Circumstances on Components of Stress: For two men collaborating or negotiating under stressful circumstances, caffeine consumption was bad news, undermining their performance and confidence. By contrast, for pairs of women, drinking caffeine often had a beneficial effect on these same factors. The differential effect of caffeine on men and women may have to do with the fact that women tend to respond to stress in a collaborative, mutually protective style (known as 'tend and befriend') whereas men usually exhibit a fight or flight response.

Douglas McWilliams, Centre for Economics and Business Research: Top ten predictions for 2011 include yet another euro crisis, slower growth, retirement at 75 (in Japan). Yet another eurozone crisis in the spring if not before, when Spain and Italy have to refinance in aggregate over €400 billion of bonds. The euro might break up at this point, though European politicians are normally able to respond to a crisis and I suspect that what will break up the euro will be the failure of most of the countries to take the tough medicine necessary to make their economies competitive over the longer term. We give it only a one in five chance of surviving in its present form for ten years. If the euro doesn’t break up, this could be the year when it weakens substantially towards parity with the dollar.

Zsolt Darvas, Jean Pisani-Ferry, Bruegel: The Threat of 'Currency Wars': A European Perspective. The so-called ‘currency war’ is manifested in three ways: 1) the inflexible pegs of undervalued currencies; 2) attempts by floating exchange-rate countries to resist currency appreciation; 3) quantitative easing. Europe should primarily be concerned about the first issue, which relates to the renewed debate about the international monetary system. The attempts of floating exchange-rate countries to resist currency appreciation are generally justified while China retains a peg. Quantitative easing cannot be deemed a ‘beggar-thy-neighbour’ policy as long as the Fed’s policy is geared towards price stability. Current US inflationary expectations are at historically low levels. Central banks should come to an agreement about the definition of price stability at a time of deflationary pressures. The euro’s exchange rate has not been greatly impacted by the recent currency war; the euro continues to be overvalued, but less than before.

Simon Johnson, Global Monitor: Why Can’t Europe Avoid Another Crisis? Why Can’t the U.S.? Most experienced watchers of the eurozone are expecting another serious crisis to break out in early 2011.  This projected crisis is tied to the rollover funding needs of weaker eurozone governments, i.e., debts falling due in March through May, and therefore seems much more predictable than what happened to Greece or Ireland in 2010.  The investment bankers who fell over themselves to lend to these countries on the way up, now lead the way in talking up the prospects for a serious crisis. This crisis is not more preventable for being predictable because its resolution will involve politically costly steps – which, given how Europe works, can only be taken under duress. And don’t smile as you read this, because this same logic points directly to a deep and morally disturbing crisis heading directly at the United States.

Kenneth Rogoff, Project Syndicate: Armageddon Can Wait. Where are global currencies headed in 2011? After three years of huge, crisis-driven exchange-rate swings, it is useful to take stock both of currency values and of the exchange-rate system as a whole. And my best guess is that we will see a mix of currency wars, currency collapses, and currency chaos in the year ahead – but that this won’t spell the end of the economic recovery, much less the end of the world.

Christopher D. Carroll, Misuzu Otsuka, Jiri Slacalek, ECB: How Large are Housing and Financial Wealth Effects? This paper presents a simple new method for measuring `wealth effects' on aggregate consumption. The method exploits the stickiness of consumption growth (sometimes interpreted as reecting consumption `habits') to distinguish between immediate and eventual wealth effects. In U.S. data, we estimate that the immediate (next-quarter) marginal propensity to consume from a $1 change in housing wealth is about 2 cents, with a nal eventual effect around 9 cents, substantially larger than the effect of shocks to financial wealth. We argue that our method is preferable to cointegration-based approaches, because neither theory nor evidence supports faith in the existence of a stable cointegrating vector.

Reuven Glick, Kevin J. Lansing, San Francisco Fed: Consumers and the Economy, Part I: Household Credit and Personal Saving. In the years since the bursting of the housing bubble, the personal saving rate has trended up from around 1% to around 6%, while the ratio of household debt to disposable income has dropped from 130% to 118%. Changes over time in the availability of credit to households can explain 90% of the variance of the saving rate since the mid-1960s, including the recent uptrend, according to a simple empirical model.

Dhaval M. Dave, Inas Rashad Kelly, NBER:  How Does the Business Cycle Affect Eating Habits? A higher risk of unemployment is associated with reduced consumption of fruits and vegetables and increased consumption of "unhealthy" foods such as snacks and fast food.  Among individuals predicted to be at highest risk of being unemployed, a one percentage point increase in the resident state's unemployment rate is associated with a 2-8% reduction in the consumption of fruits and vegetables.  The impact is somewhat higher among married individuals and older adults.

Richard B. Freeman, Stephen Machin, Martina Viarengo, VoxEU: The virtuous equity-efficiency trade-off in educational outcomes. How countries score in international tests are seen by many as report card on their national educational policies. Summarising evidence from international maths exams, this column finds that the highest-scoring countries are those with the least inequality in test scores, suggesting a “virtuous” equity-efficiency trade-off. It also finds that countries perform even better when test scores are highly correlated with the number books in the family home.

Joshua Angrist, Philip Oreopoulos, Tyler Williams, NBER: When Opportunity Knocks, Who Answers? New Evidence on College Achievement Awards. We evaluate the effects of academic achievement awards for first and second-year college students on a Canadian commuter campus. The award scheme offered linear cash incentives for course grades above 70. Awards were paid every term. Program participants also had access to peer advising by upperclassmen. Program engagement appears to have been high but overall treatment effects were small. The intervention increased the number of courses graded above 70 and points earned above 70 for second-year students, but there was no significant effect on overall GPA. Results are somewhat stronger for a subsample that correctly described the program rules. We argue that these results fit in with an emerging picture of mostly modest effects for cash award programs of this type at the post-secondary level.

Anh T. Le, IZA: Attitudes towards Economic Risk and the Gender Pay Gap. This paper examines the links between gender differences in attitudes towards economic risk and the gender pay gap. Consistent with the literature on the socio-economic determinants of attitudes towards economic risk, it shows that females are much more risk averse than males. It then extends this research to show that workers with more favorable attitudes towards risk are associated with higher earnings, and that gender differences in attitudes towards economic risk can account for a small, though important, part of the standardized gender pay gap.

Henrik Kleven, Camille Landais, Emmanuel Saez, NBER: Taxation and International Migration of Superstars: Evidence from the European Football Market. We construct a panel data set of top earnings tax rates, football player careers, and club performances in the first leagues of 14 European countries since 1980. We then set out a theoretical model of taxation and migration, which is structurally estimated using all sources of tax variation simultaneously. Our results show that (i) the overall location elasticity with respect to the net-of-tax rate is positive and large, (ii) location elasticities are extremely large at the top of the ability distribution but negative at the bottom due to ability sorting effects, and (iii) cross-tax effects of foreign players on domestic players (and vice versa) are negative and quite strong due to displacement effects. Finally, we estimate tax
revenue maximizing rates and draw policy conclusions.

David Maddison, Katrin Rehdanz, Kiel Institute: The Impact of Climate on Life Satisfaction. We analyse the influence of climate on average life satisfaction in 87 countries using data from the World Values Survey. Climate is described in terms of ‘degree-months’ calculated using an optimally-selected base temperature of 65°F (18.3°C). Our results suggest that countries with climates characterised by a large number of degree-months enjoy significantly lower levels of life satisfaction. This finding is robust to a wide variety of model specifications. Using our results to analyse a particular climate change scenario associated with the IPCC A2 emissions scenario points to major losses for African countries, but modest gains for Northern Europe

Mara Squicciarini, Jo Swinnen, University of Leuven: Women or Wine ? Monogamy and Alcohol. Intriguingly, across the world the main social groups which practice polygyny do not consume alcohol. We investigate whether there is a correlation between alcohol consumption and polygynous/monogamous arrangements, both over time and across cultures. Historically, we find a correlation between the shift from polygyny to monogamy and the growth of alcohol consumption. Cross-culturally we also find that monogamous societies consume more alcohol than polygynous societies in the preindustrial world. We provide a series of possible explanations to explain the positive correlation between monogamy and alcohol consumption over time and across societies.

Jan-Emmanuel De Neve et al,  CREMA: Genes, Economics, and Happiness. Using data from Add Health, we employ a twin study design to show that genetic variation explains about 33% of the variation in happiness, and that the influence of genes varies by gender (women 26%, men 39%) and tends to rise with age. We also present evidence that variation in a specific gene predicts happiness. Individuals with a transcriptionally more efficient version of the serotonin transporter gene (SLC6A4) are significantly more likely to report higher levels of life satisfaction.  

Timo Boppart, Josef Falkinger, Volker Grossmann, IZA: Protestantism and Education: Reading (the Bible) and Other Skills. During industrialization, Protestants were more literate than Catholics. This paper investigates whether this fact may be led back to the intrinsic motivation of Protestants to read the bible and whether other education motives were involved as well. We employ a historical data set from Switzerland which allows us to differentiate between different cognitive skills: reading, numeracy, essay writing and Swiss history. We develop an estimation strategy to examine whether the impact of religious denomination was particularly large with respect to reading capabilities. We find support for this hypothesis. However, Protestants’ education motives went beyond reading the bible.

Barry Eichengreen, National Interest: Mr. Bernanke Goes to War. Reassuring foreign central banks and governments with big investments in American Treasury securities would require Washington to put in place a credible plan for balancing the federal government budget. It would require putting the social security trust fund on a sustainable footing. It would require solving once and for all the problem of Medicare and Medicaid costs. Not only would emerging markets be reassured, but the United States itself would be better off. Averting a currency war, then, is simple. Doing so doesn’t require some grand bargain between the United States and China. It only requires each party to recognize what is in its self-interest. Restoring peace and harmony to the financial sphere doesn’t require an outbreak of international cooperation. It only requires an outbreak of common sense.

Véronique Genre et al, ECB: Combining the forecasts in the ECB survey of professional forecasters: can anything beat the simple average? For GDP growth and the unemployment rate, only few of the forecast combination schemes are able to outperform the simple equal-weighted average forecast. Conversely, for the inflation rate there is stronger evidence that more refined combinations can lead to improvement over this benchmark. In particular, for this variable, the relative improvement appears significant even controlling for data snooping bias.

Michelle L. Barnes, N. Aaron Pancost, Boston Fed: Internal Sources of Finance and the Great Recession. The rising stockpile of cash as a share of total assets at U.S. firms has intrigued economists since at least the paper of Bates, Kahle, and Stulz (2006), yet there has been relatively little work on where this cash has come from and how it is related to investment performance. We exploit Statement of Cash Flows data from Compustat to decompose firms’ cash stocks and show that the rise in cash holdings has coincided with an increased willingness to save internally generated cash. We show that although investment is normally sensitive to externally generated cash, the increased sensitivity of investment to cash during the Great Recession is driven by cash from internal sources. Smaller firms were also more affected by the recent downturn than larger firms. Our results agree with the findings of Almeida, Campello, and Weisbach (2004) on cash hoarding and financial constraints, as well as the estimates in Duchin, Ozbas, and Sensoy (2010) on the important role of saved cash during the financial crisis.

Uri Dadush, VoxEU: Who gains from a renminbi revaluation? If China appreciates its currency, who will gain and who will lose out? This column argues that the single greatest beneficiary from a gradual renminbi revaluation, accompanied by measures to stimulate demand, will be China itself. Ironically, the US, which has been leading the charge on renminbi appreciation, would likely be among the losers. Certainly, a very large one-off revaluation that disrupts China’s growth hurts everyone.

Knut Røed, Jens Fredrik Skogstrøm, IZA: Creative Unemployment. We examine the impact of job loss on entrepreneurship behavior in Norway. Our identification strategy relies on the use of mass layoffs caused by bankruptcies as indicators of exogenous displacement. We find that working in a company which is going to close down due to bankruptcy during the next four years raises the subsequent entrepreneur rate by 3.7 percentage points (155 %) for men and 1.8 percentage points (180 %) for women, compared to working in a stable firm. These estimates are much larger than what has previously been reported in the literature. Taking into account that many workers lose their jobs in the comparison group of stable firms also, we reckon that the full effects of displacement are even larger.

Torbjørn Haegeland et al, IZA: Why Children of College Graduates Outperform their Schoolmates: A Study of Cousins and Adoptees. Massive cross-sectional evidence exists indicating that children of more educated parents outperform their schoolmates. However, evidence for causal interpretation of this association is weak. We examine a causal relationship using two approaches for identification within the same data: cousins with twin parents and adopted children. We find no effect of mothers' education on children's school performance using the children-of-twins approach. However, for adopted children, mother's education has a small positive effect. Tracking the work experience of parents during offspring childhood, we find no support that this effect can be explained by a higher labor force participation among more educated mothers.

Merwan Engineer, Ian King, University of Victoria: Maximizing Human Development. The Human Development Index (HDI) is widely used as an aggregate measure of overall human well being. We examine the allocations implied by the maximization of this index, using a standard growth model — an extended version of Mankiw, Romer, andWeil’s (1992) model — and compare these with the allocations implied by the golden rule in that model. We find that maximization of the HDI leads to the overaccumulation of both physical and human capital, relative to the golden rule, and consumption is pushed to minimal levels. We then propose an alternative specification of the HDI, which replaces its income component with a consumption component. Maximization of this modified HDI yields a “human development golden rule” which balances consumption, education and health expenditures, and avoids the more extreme implications of the existing HDI.

Most analyses of teacher quality end without any assessment of the economic value of altered teacher quality. This paper combines information about teacher effectiveness with the economic impact of higher achievement. It begins with an overview of what is known about the relationship between teacher quality and student achievement. This provides the basis for consideration of the derived demand for teachers that comes from their impact on economic outcomes. Alternative valuation methods are based on the impact of increased achievement on individual earnings and on the impact of low teacher effectiveness on economic growth through aggregate achievement. A teacher one standard deviation above the mean effectiveness annually generates marginal gains of over $400,000 in present value of student future earnings with a class size of 20 and proportionately higher with larger class sizes. Alternatively, replacing the bottom 5-8 percent of teachers with average teachers could move the U.S. near the top of international math and science rankings with a present value of $100 trillion.

Christian Helmers, Mark Rogers, VoxEU: The impact of university research on corporate patenting. There is broad agreement that research at universities has knock-on benefits for innovation and the wider economy in general. The question remains “how?”. This column presents evidence from across the UK suggesting that local university research has a positive effect on the number local small firms that patent and that this effect strengthens the better the university.

Steve Martin, Paul Dolan, Harvard Business Review: Dear Taxpayer, Congratulations! You've Won Your Money Back. In 2007, the Internal Revenue Service (IRS) introduced a series of additional penalties for any US citizen who knowingly submitted a less than complete and honest tax return. While understandable the approach was anything but successful. In fact, it resulted in a 22% increase in tax fraud the following year. We wonder if a lottery might provide a more positive and innovative approach to dealing the problem. Every citizen who submits their tax return and payment honestly and on time has their social security number entered in a lottery with a number (to be determined) of citizens winning a prize. What might that prize be? How about a letter from the IRS with a check:
"Dear Taxpayer, Congratulations! You've won your money back."

Jonah Lehrer, NYT: A Physicist Solves the City. West saw the metropolis as a sprawling organism, similarly defined by its infrastructure. (The boulevard was like a blood vessel, the back alley a capillary.) This implied that the real purpose of cities, and the reason cities keep on growing, is their ability to create massive economies of scale, just as big animals do. After analyzing the first sets of city data — the physicists began with infrastructure and consumption statistics — they concluded that cities looked a lot like elephants. In city after city, the indicators of urban “metabolism,” like the number of gas stations or the total surface area of roads, showed that when a city doubles in size, it requires an increase in resources of only 85 percent.

There is broad agreement that research at universities has knock-on benefits for innovation and the wider economy in general. The question remains “how?”. This column presents evidence from across the UK suggesting that local university research has a positive effect on the number local small firms that patent and that this effect strengthens the better the university.

Steve Martin, Paul Dolan, Harvard Business Review: Dear Taxpayer, Congratulations! You've Won Your Money Back. In 2007, the Internal Revenue Service (IRS) introduced a series of additional penalties for any US citizen who knowingly submitted a less than complete and honest tax return. While understandable the approach was anything but successful. In fact, it resulted in a 22% increase in tax fraud the following year. We wonder if a lottery might provide a more positive and innovative approach to dealing the problem. Every citizen who submits their tax return and payment honestly and on time has their social security number entered in a lottery with a number (to be determined) of citizens winning a prize. What might that prize be? How about a letter from the IRS with a check:

"Dear Taxpayer, Congratulations! You've won your money back."

Jonah Lehrer, NYT: A Physicist Solves the City. West saw the metropolis as a sprawling organism, similarly defined by its infrastructure. (The boulevard was like a blood vessel, the back alley a capillary.) This implied that the real purpose of cities, and the reason cities keep on growing, is their ability to create massive economies of scale, just as big animals do. After analyzing the first sets of city data — the physicists began with infrastructure and consumption statistics — they concluded that cities looked a lot like elephants. In city after city, the indicators of urban “metabolism,” like the number of gas stations or the total surface area of roads, showed that when a city doubles in size, it requires an increase in resources of only 85 percent.

Art Carden, Forbes Blog: How Economics Saved Christmas.

Every Who down in Whoville liked Christmas a lot

But the Grinch, who lived just north of Whoville, DID NOT

He stood and he hated the Whos and their noise

He hated the shrieks of the Who girls and boys

For fifty-three years he’d put up with it now—

He had to stop Christmas from coming, somehow

He asked and he questioned the whole thing’s legality

Then his eyes brightened: he screamed “externality!”

He reached for his textbooks; he knew what to do

He’d fight them with ideas from A.C. Pigou

This idea has merit, he thought in the frost

A tax that was equal to external cost.

James Andreoni, Justin M Rao, VoxEU: Do they know it's Christmas? New insights on communication, empathy, and altruism. At a time when many people are asking themselves what to give their friends and family for Christmas, this column asks why we bother to give anything at all. In the economic laboratory, subjects exhibit significant levels of altruistic giving and aversion to unfairness. Outside the laboratory however, we encounter vast amounts of poverty and inequality and yet only give a tiny fraction of our income to charity.

Ran Abramitzky, Liran Einav, Oren Rigbi, The Economic Journal: Is Hanukkah Responsive to Christmas? We use individual-level survey and county-level expenditure data to examine the extent to which Hanukkah celebrations among US Jews are driven by the presence of Christmas. We document that Jews with young children are more likely to celebrate Hanukkah, that this effect is greater for reform Jews and for strongly-identified Jews, and that Jewish-related expenditure on Hanukkah is higher in counties with lower shares of Jews. All these findings are consistent with the hypothesis that celebration of religious holidays is designed not only for worship and enjoyment but also to provide a counterbalance for children against competing cultural influences.

Gregor Schubert, Princetonian: The cruelty of Christmas gifts. True human affection should be a continuous and calendar-independent flow of generosity, and I hope that this year we will fight to abandon the cruel practice of Christmas gifts. While there might be an economic rationale for these transactions, the human cost of such materialist emotional impoverishment is simply too great for those of us with kind hearts to tolerate.

Robin Hanson, Overcomingbias Blog: Christmas Signaling: Why don't we give each other cash for Christmas? The usual answer is your Christmas gift is a signal, not just of your willingness to sacrifice cash for them, but also of how well you know them, to know what they want. But if so then why do we often make and distribute Christmas wish lists? One answer might be that the gift receiver is like a teacher leaking answers to students to raise her teacher rating – maybe the gift receiver cares more that third parties think her gift givers know her well, than that they actually know her well. But in this case wouldn't she be trying to hide the fact that she passed around a wish list? If everyone who sees her get a gift was shown the wish list, who could she be fooling?

Mark Whitehouse, WSJ: How Christmas Brings Out The Grinch in Economists. Given the fanfare and billions of dollars in spending it generates, you might think Christmas is the best thing to happen to the economy all year. But some economists say we would be better off without it. In the cold, hard analysis of the dismal science, Christmas is a highly inefficient way of connecting consumers with goods. Squeezing a big chunk of people's spending into a year-end frenzy of gift-buying generates an abundance of ill-considered presents -- millions of unwanted ties, picture frames and toe socks that, had they found the right owners, could have brought a lot more satisfaction.

Allen R. Sanderson, Chicago Life: Gift Books for Econ Lovers. Extending this playful side, economists have also ventured into the realm of fiction. No mistaking them for Agatha Christie; nevertheless, these aren’t bad: the ‘Marshall Jevons’ volumes, Murder at the Margin, The Fatal Equilibrium and A Deadly Indifference; three by Russell Roberts, The Choice, The Invisible Heart, and The Price of Everything; and two by Michael Walden and M.E. Whitman Walden, Micro Mayhem and Micro Mischief.

Barry Eichengreen, Project Syndicate: Europe’s Inevitable Haircut. This simple fact creates a fundamental contradiction for the internal devaluation strategy: the more that countries reduce wages and costs, the heavier their inherited debt loads become. And, as debt burdens become heavier, public spending must be cut further and taxes increased to service the government’s debt and that of its wards, like the banks. This, in turn, creates the need for more internal devaluation, further heightening the debt burden, and so on, in a vicious spiral downward into depression. So, if internal devaluation is to work, the value of debts, where they already represent a heavy burden, must be reduced. Government debt must be restructured. Bank debts have to be converted into equity and, where banks are insolvent, written off. Mortgage debts, too, must be written down.

Edward L. Glaeser, NYT Blog: Does Economic Inequality Cause Crises? The Nobel Laureate Joseph Stiglitz’s theory is that “growing inequality in most countries of the world has meant that money has gone from those who would spend it to those who are so well off that, try as they might, they can’t spend it all. Jean-Paul Fitoussi and Francesco Saraceno have made similar arguments. A related view, called the Stiglitz hypothesis, by Sir Anthony Atkinson and Salvatore Morelli, is that “in the face of stagnating real incomes, households in the lower part of the distribution borrowed to maintain a rising standard of living,” and “this borrowing later proved unsustainable, leading to default and pressure on over-extended financial institutions.” Another view, associated with Raghuram Rajan, former chief economist of the International Monetary Fund, is that “the political response to rising inequality – whether carefully planned or the path of least resistance – was to expand lending to households, especially low-income households.”

Michael Kumhof, Romain Rancière, IMF: Inequality, Leverage and Crises. The paper studies how high leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2008 both exhibited a large increase in the income share of the rich, a large increase in leverage for the remainder, and an eventual financial and real crisis. The paper presents a theoretical model where these features arise endogenously as a result of a shift in bargaining powers over incomes. A financial crisis can reduce leverage if it is very large and not accompanied by a real contraction.

Oscar Jorda, Moritz Schularick, Alan M. Taylor, NBER: Financial Crises, Credit Booms, and External Imbalances: 140 Years of Lessons. We study the experience of 14 developed countries over 140 years (1870-2008). We exploit our long-run dataset in a number of different ways. First, we apply new statistical tools to describe the temporal and spatial patterns of crises and identify five episodes of global financial instability in the past 140 years. Second, we study the macroeconomic dynamics before crises and show that credit growth tends to be elevated and natural interest rates depressed in the run-up to global financial crises. Third, we show that recessions associated with crises lead to deeper recessions and stronger turnarounds in imbalances than during normal recessions. Finally, we ask if external imbalances help predict financial crises. Our overall result is that credit growth emerges as the single best predictor of financial instability, but the correlation between lending booms and current account imbalances has grown much tighter in recent decades.

Luiz de Mello, Pier Carlo Padoan, Linda Rousová, VoxEU: Monitoring global imbalances: Determinants and policy implications of current-account reversals. Are global imbalances sustainable? This column analyses nearly 160 current-account reversals across 101 countries between 1971 and 2007. It argues that with the right policy framework, external imbalances can be monitored and, to some extent, managed.

Rémi Bazillieryand, Yasser Moullan, Université d’Orléans: Employment Protection and Migration. Empirically, we show that employment protection differential between source and destination countries is an important determinant of bilateral migration. Bilateral migration of workers is negatively affected by this differential of employment protection. This effect is stronger for high-skilled workers. We also find that the effect of the differential is largely explained by the level of employment protection in destination countries. This factor does not have a significant impact in origin countries. These results are obtained controling econometrically for the high proportion of zero using Heckman two steps procedure. Overall, we find that, contrary to the conventional wisdom, migrants are not attracted by protective legislation. On the contrary, they tend to move where this protection is closer to the one of their origin country.

Pedro Carneiro, Katrine V. Loken, Kjell G. Salvanes: A Flying Start? Long Term Consequences of Maternal Time Investments in Children During Their First Year of Life. We study the impact on children of increasing the time that the mother spends with her child in the first year by exploiting a reform that increased paid and unpaid maternity leave in Norway. The reform increased maternal leave on average by 4 months and family income was unaffected. The increased time with the child led to a 2.7 percentage points decline in high school dropout. For mothers with low education we find a 5.2 percentage points decline. The effect is also especially large for children of mothers who, prior to the reform, would take very low levels of unpaid leave.

Andreas Peichl, Sebastian Siegloch, IZA: Accounting for Labor Demand Effects in Structural Labor Supply Models. When assessing the effects of policy reforms on the labor market, most studies only focus on labor supply. The interaction of supply and demand side is not explicitly modeled, which might lead to biased estimates of potential labor market outcomes. This paper proposes a straightforward method to remedy this shortcoming. We use information on firms’ labor demand behavior and feed them into a structural labor supply model, completing the partial analysis of the labor market on the microdata level. We show the performance and relevance of our extension by introducing a pure labor supply side reform, the workfare concept, in Germany and simulating the labor market outcome of the reform. We find that demand effects offset about 25 percent of the positive labor supply effect of the policy reform.

Cara Buckley, NYT: To Test Housing Program, Some Are Denied Aid. It has long been the standard practice in medical testing: Give drug treatment to one group while another, the control group, goes without. Now, New York City is applying the same methodology to assess one of its programs to prevent homelessness. Half of the test subjects — people who are behind on rent and in danger of being evicted — are being denied assistance from the program for two years, with researchers tracking them to see if they end up homeless. But some public officials and legal aid groups have denounced the study as unethical and cruel, and have called on the city to stop the study and to grant help to all the test subjects who had been denied assistance.

Chris Dillow, Stumbling and Mumbling Blog: Egonomics. When I was young and stupid - ills of which I am now half-cured - I thought that wealth and fame arose from merit. As I got older, I thought they were more due to luck. But now I think I was wrong. They arise instead from ego. Whether it is the desire to think well of oneself, or to believe that others do so, or the belief that one’s talents entitle one to a “distinguished” position, it is, I suspect, ego that is the motive force, rather than a desire for wealth. What I’m getting at here is that the bog-standard economistic view that we are motivated by money is horribly incomplete - except at a (perhaps narrow) margin. It is instead vanity and ego that drives many of us.

Mulholland, Sean, Tomic, Aleksandar, Sholander, Samuel, Stonehill College: The Faculty Flutie Factor: Does Football Performance Affect a University’s US News and World Report Peer Assessment Score? Analyzing the peer assessment portion of the US News and World Report’s college rankings, we find that administrators and faculty rate more highly universities whose football team receives a greater number of votes in either the final Associated Press or Coaches Poll. Controlling for unobserved heterogeneity, our estimates suggest that a one standard deviation increase in the number of votes received in either the Associated Press or USA Today Coaches’ Football Poll is viewed as positively as a forty point increase in a school’s SAT score at the 75th percentile.

Tyler Durden, Zero Hedge Blog: Goldman Jumps Shark, "Fundamentally" Shifts Its "Bearish" Outlook On Economy: Goes Bullish, Hikes Outlook. This outlook represents a fundamental shift in the thinking that has governed our forecast for at least the last five years... Five years ago, we became very pessimistic about the US economic outlook. This was because we expected downturns in the housing and mortgage markets to trigger a substantial increase in the private sector financial balance—the gap between the total income and total spending of US households and businesses. So why do we now expect growth to pick up? In a nutshell, it is because underlying demand has strengthened significantly.

Bart Hobijn, Colin Gardiner, San Francisco Fed: The Breadth of Disinflation. In recent months, inflation as measured by the personal consumption expenditures price index has been trending lower. This slowdown, known as disinflation, has raised concerns that inflation might actually drop below zero and enter a period of deflation. An examination of the distribution of inflation rates across the range of goods and services that compose the index suggests that downward pressures on inflation are relatively high by historical standards.

Simon Johnson, Economix: How Likely Is Default in Europe? If it is decided your country is insolvent, rather than illiquid, then you have to restructure your debts. But who will decide? Here is the bombshell in the document: “On this basis, the Eurogroup Ministers will take a unanimous decision on providing assistance.” In other words, any one member of the euro zone can veto a country from being determined merely illiquid, thus cutting it off from cheap and endless credit (from the European Central Bank or European Stability Mechanism or any window to be named later). So now Germany effectively has a veto, as do other fiscally austere countries.

Barry Eichengreen, VoxEU: Ireland’s rescue package: Disaster for Ireland, bad omen for the Eurozone. Irish interest spreads did not fall and contagion continues. Here one of the world’s leading international economists explains why. Short-sighted, wishful thinking by EU and German leadership designed a package that is not economically feasible in the long run (it would trigger a vicious debt deflation spiral) and it is not politically sustainable in the short run. The Eurozone had better have a Plan B for when the new Irish government rejects the package next year and imposes a haircut on Irish bank bondholders.

Free exchange Blog: Europe's economy: How to devalue without devaluing. Spain needs to become more competitive relative to Germany, but it can't shift its nominal exchange rate with Germany, because they share the same currency. But if inflation rates in the two countries diverge—if German inflation rises faster than Spanish inflation—then the real effective exchange rate will move in Spain's favour despite the shared currency. Why might we expect German inflation to rise faster than that elsewhere? The main reason is the divergence in economic conditions between the two areas. Germany's economy has been booming in recent quarters, and unemployment there has fallen. In debt-stricken Europe, however, growth has been weak (or non-existent). Unemployment is high, real estate costs are falling, and so we'd expect inflation in such places to be subdued while prices in Germany face upward pressure. Voila; revaluation without abandoning the euro.

Daniel Gros, VoxEU: All together now? Arguments for a big-bang solution to Eurozone problems. Muddling through isn’t working. This column argues that troubled Eurozone nations should simultaneously open restructuring talks while continuing to service their debts normally. Germany, France, and other core Eurozone nations would have to stand ready to recapitalise the banks most exposed to the restructured debt. The ECB would then stabilise the banking system and the EFSF would stabilise sovereign debt. This big bang could be prepared in a weekend; the market already seems to be pricing it in.

Catherine Rampell, NYT Blog: Will Today’s Unemployed Become Tomorrow’s Unemployable? Cyclical unemployment can become structural unemployment because perfectly good workers become less employable the longer they are out of work. Economists have long known this to be the case, and have documented that the likelihood of finding a job falls drastically the longer a person has been unemployed. For workers with duration less than six months, the job finding probability averages 31 percent. It falls to 19 percent during the next six months and just 14 percent for workers who have been unemployed for over a year.

Marco Leonardi, Giovanni Pica, IZA: Who Pays for It? The Heterogeneous Wage Effects of Employment Protection Legislation. Theory predicts that the wage effects of government-mandated severance payments depend on workers' and firms' relative bargaining power. This paper estimates the effect of employment protection legislation (EPL) on workers' individual wages in a quasi-experimental setting, exploiting a reform that introduced unjust-dismissal costs in Italy for firms below 15 employees and left firing costs unchanged for bigger firms. Accounting for the endogeneity of the treatment status, we find that high-bargaining power workers (stayers, white collar and workers above 45) are almost left unaffected by the increase in EPL, while low-bargaining power workers (movers, blue collar and young workers) suffer a drop both in the wage level and its growth rate.

Andreas Schick, Richard H. Steckel, NBER: Height as a Proxy for Cognitive and Non-Cognitive Ability.Taller workers receive a substantial wage premium. Studies extending back to the middle of the last century attribute the premium to non-cognitive abilities, which are associated with stature and rewarded in the labor market. More recent research argues that cognitive abilities explain the stature-wage relationship. This paper reconciles the competing views by recognizing that net nutrition, a major determinant of adult height, is integral to our cognitive and non-cognitive development. Using data from Britain’s National Childhood Development Study (NCDS), we show that taller children have higher average cognitive and non-cognitive test scores, and that each aptitude accounts for a substantial and roughly equal portion of the stature premium. Together these abilities explain why taller people have higher wages.

Andrew J. Rotherham, Time: School of Thought. Is the Golden Age of Education Spending Over? The more general problem with school funding is the lack of attention to productivity, i.e., thinking about outputs (student learning) in relation to inputs (spending). In education circles, productivity is a four-letter word. Cost and benefits? Never heard of 'em! Elementary and secondary education remains one of the last industries relatively untouched over the past few decades by productivity increases from new technologies. Schools still operate pretty much the same way they did when our parents were student. In fact, rather than becoming more productive, the opposite has happened in education: over the last 30 years, public schools have focused on strategies that decrease productivity.

Armine Yalnizyan, Canadian Centre for Policy Alternatives: The Rise of Canada’s Richest 1%. Surprisingly, the incomes of the richest Canadians are increasingly reliant on their jobs, just like the rest of us. That’s a big change from the past. In 1946, just after the end of the Second World War, their paycheques accounted for less than half their income (45.5%). Today over two-thirds of their incomes (67.6%) come from wages, with the balance mostly coming from professional fees, dividends, interest and investment income. In fact, the richest 0.01% rely on their jobs for almost three-quarters of their income (73.5%), just like the average Canadian. The difference is their work is much more richly rewarded. The richest 1% is increasingly like the average Canadian in another regard too: reliance on business income. In 1946, 24.3% of the incomes of the richest 1% came from running a business. That dropped to 3.1% in 2007 — the very same as for the average Canadian.

Maxim Pinkovskiy, Xavier Sala-i-Martin, VoxEU: African poverty is falling…much faster than you think. Sub-Saharan Africa has made little progress in reducing extreme poverty, according to the latest Millennium Development Report. This column presents evidence from 1970 to 2006 to the contrary.

James Mcwilliams, NYT Blog: The Rational War on Fat. The problem with taxing sodas alone is that the tax only works to lower obesity rates if consumers decrease overall caloric intake, not just of soda. When it comes to taxing carbonated beverages, what guarantee is there that consumers won’t compensate—or even overcompensate—elsewhere for the calories lost to soft drinks? Absolutely none. And thus it’s no surprise that a 2009 study found sales taxes to have had minimal impact on obesity. We can tax individual items until the coffers spill over, but until we can figure out how to tax excess calories rather than the sources of them, this approach to placing the nation on a much needed diet will have a sclerotic impact at best. When it comes to food, I would venture to say that we’re all irrational. Is it likely that we’ll consistently follow the perfectly rational incentives designed by benevolent governmental guardians? Fat chance.

Tyler Cowen, Marginal Revolution Blog: Why Timur Kuran is one of our most important thinkers. He now has a new book out -- The Long Divergence: How Islamic Law Held Back the Middle East. The book explains a large part of why the Middle East and Turkey fell behind the West and law and economics has a lot to do with it. Various laws in Islamic societies were not conducive to large-scale economic structures, at precisely the time when such structures were becoming profitable and indeed essential as drivers of economic growth. Here is a short excerpt from the book:” ...several institutions...blocked evolutionary paths in the direction of modern banking: the Islamic law of commercial partnerships, the Islamic inheritance system, the waqf system, and the individualism of Islamic law. All were introduced earlier as causes of the region's other handicaps. Like the region's previously discussed symptoms of underdevelopment, delayed financial modernization was an unintended consequence of institutional choices that served laudable objectives.”
