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.

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.
Eric A. Hanushek, NBER: The Economic Value of Higher Teacher Quality.
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

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.

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.

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

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.

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
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.

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.
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
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
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.

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.
