Edward Hugh Blog: And Then There Were None. According to one popular analogy currently circulating , the EuroArea countries could be likened to a group of 16 Alpine climbers scaling the Matterhorn who find themselves tightly roped together in appalling weather conditions. One of the climbers - Greece – has lost his footing and slipped over the edge of a dangerous precipice. As things stand, the other 15 can easily take the strain of holding him dangling there, however uncomfortable it may be for them, but they cannot quite manage to pull their colleague back up again. So, as the day advances, others, wearied by all the effort required, start themselves to slide. First it is Ireland who moves closest to the edge, getting nearer and nearer to the abysss with each passing moment. And just behind Ireland comes Portugal, while some way further back Spain lies Spain, busily consoling itself that it is in no way as badly off as the others who have already lost there footing. But for heavens sake, the only thing we don't need while we sit here biting our nails is to be told by someone who manifestly has no idea what he is talking about that the danger has already past, even as we slide, inch by inch, onwards and downwards towards the chasm that gapes beneath.

David Lang, Kevin J. Lansing, San Francisco Fed: Forecasting Growth over the Next Year with a Business Cycle Index. Forecasts derived from business cycle indicators produced by the Chicago and Philadelphia Federal Reserve Banks predict that real U.S. GDP growth through the first half of 2011 will remain at or below potential growth. If these forecasts prove accurate, then the historical relationship between real GDP growth and the labor market suggests that the unemployment rate could rise by as much as 0.5 percentage point during this period.

Jordi Galí, NBER: Are Central Banks' Projections Meaningful? Central banks' projections–i.e. forecasts conditional on a given interest rate path–are often criticized on the grounds that their underlying policy assumptions are inconsistent with the existence of a unique equilibrium in many forward-looking models. Here I describe three alternative approaches to constructing projections that are not subject to the above criticism, using two different versions of New Keynesian model as reference frameworks. Most importantly, I show how the three approaches generate different projections for inflation and output, even though they imply an identical path for the interest rate. The latter result calls into question the meaning and usefulness of such projections.

Martin Feldstein, Project Syndicate: Japan’s Savings Crisis. Japan is heading toward a savings crisis. The potential future clash between larger fiscal deficits and a low household saving rate could have powerful negative effects on both Japan and the global economy. Japan’s ability to sustain high fiscal deficits, low interest rates, and net capital exports has been possible because of its high private saving rate, which has kept national saving positive. But, with the current low rate of household saving, the cycle of rising deficits and debt will soon make national saving negative. A shift from deflation to low inflation would accelerate this process. If Japan’s domestic net saving surplus vanishes, the current $175 billion of capital outflow would no longer be available to other countries, while Japan might itself become a net drain on global savings.

Alan Auerbach, Yuriy Gorodnichenko, University of California: Measuring the Output Responses to Fiscal Policy.A key issue in current research and policy is the size of fiscal multipliers when the economy is in recession. Using a variety of methods and data sources, we provide three insights. First, using regime-switching models, we estimate effects of tax and spending policies that can vary over the business cycle; we find large differences in the size of fiscal multipliers in recessions and expansions with fiscal policy being considerably more effective in recessions than in expansions. Second, we estimate multipliers for more disaggregate spending variables which behave differently in relation to aggregate fiscal policy shocks, with military spending having the largest multiplier. Third, we show that controlling for predictable components of fiscal shocks tends to increase the size of the multipliers.

Christiane Nickel, Philipp Rother, Lilli Zimmermann, ECB: Major public debt reductions: Lessons from the past, lessons for the future. Our findings suggest that, first, major debt reductions are mainly driven by decisive and lasting (rather than timid and short-lived) fiscal consolidation efforts focused on reducing government expenditure, in particular, cuts in social benefits and public wages. Second, robust real GDP growth also increases the likelihood of a major debt reduction because it helps countries to "grow their way out" of indebtedness. Third, high debt servicing costs play a disciplinary role strengthened by market forces and require governments to set up credible plans to stop and reverse the increasing debt ratios.

Raj Chetty et al, NBER: How Does Your Kindergarten Classroom Affect Your Earnings? Evidence From Project STAR. In Project STAR, 11,571 students in Tennessee and their teachers were randomly assigned to different classrooms within their schools from kindergarten to third grade. This paper evaluates the long-term impacts of STAR using administrative records. We obtain five results. First, kindergarten test scores are highly correlated with outcomes such as earnings at age 27, college attendance, home ownership, and retirement savings. Second, students in small classes are significantly more likely to attend college, attend a higher-ranked college, and perform better on a variety of other outcomes. Class size does not have a significant effect on earnings at age 27, but this effect is imprecisely estimated. Third, students who had a more experienced teacher in kindergarten have higher earnings. Fourth, an analysis of variance reveals significant kindergarten class effects on earnings. Higher kindergarten class quality – as measured by classmates' end-of-class test scores – increases earnings, college attendance rates, and other outcomes. Finally, the effects of kindergarten class quality fade out on test scores in later grades but gains in non-cognitive measures persist. We conclude that early childhood education has substantial long-term impacts, potentially through non-cognitive channels. Our analysis suggests that improving the quality of schools in disadvantaged areas may reduce poverty and raise earnings and tax revenue in the long run.

Charles I. Jones, Peter J. Klenow, NBER: Beyond GDP? Welfare Across Countries And Time. We propose a simple summary statistic for a nation's flow of welfare, measured as a consumption equivalent, and compute its level and growth rate for a broad set of countries. This welfare metric combines data on consumption, leisure, inequality, and mortality. Although it is highly correlated with per capita GDP, deviations are often economically significant: Western Europe looks considerably closer to U.S. living standards, emerging Asia has not caught up as much, and many African and Latin American countries are farther behind due to lower levels of life expectancy and higher levels of inequality. In recent decades, rising life expectancy boosts annual growth in welfare by more than a full percentage point throughout much of the world. The notable exception is sub-Saharan Africa, where life expectancy actually declines.

David Card, Alexandre Mas, Enrico Moretti, Emmanuel Saez, NBER: Inequality at Work: The Effect of Peer Salaries on Job Satisfaction. A randomly chosen subset of employees of the University of California was informed about a new website listing the pay of all University employees. All employees were then surveyed about their job satisfaction and job search intentions. Our information treatment doubles the fraction of employees using the website, with the vast majority of new users accessing data on the pay of colleagues in their own department. We find an asymmetric response to the information treatment: workers with salaries below the median for their pay unit and occupation report lower pay and job satisfaction, while those earning above the median report no higher satisfaction. Likewise, below-median earners report a significant increase in the likelihood of looking for a new job, while above-median earners are unaffected. Our findings indicate that utility depends directly on relative pay comparisons, and that this relationship is non-linear.

Bryan Caplan, WSJ: The Breeders' Cup. Father's Day is a time to reflect on whether you want to be a parent—or want to be a parent again. If you simply don't like kids, research has little to say to you. If however you're interested in kids, but scared of the sacrifices, research has two big lessons. First, parents' sacrifice is much smaller than it looks, and childless and single is far inferior to married with children. Second, parents' sacrifice is much larger than it has to be. Twin and adoption research shows that you don't have to go the extra mile to prepare your kids for the future. Instead of trying to mold your children into perfect adults, you can safely kick back, relax and enjoy your journey together—and seriously consider adding another passenger.
