Increasing evidence indicates the importance of management in determining firms' productivity. Yet, causal evidence regarding the effectiveness of management practices is scarce, especially for high-skilled workers in the developed world. In an eight-month field experiment measuring the...

We examine peer effects in early education by estimating value added models with school fixed effects that control extensively for individual, family, peer, and teacher characteristics to account for the endogeneity of peer group formation. We find statistically significant and robust spillover...

This paper summarizes and extends our recent work using life satisfaction regressions to estimate the relative values of financial and non-financial job characteristics. The well-being results show strikingly large values for non-financial job characteristics, especially workplace trust and...

The sustained rise in German unemployment since 1973 poses a problem of critical importance for the world economy. Fewer than two decades ago, Germany boasted an average unemployment rate of under 1% and imported labor to relieve chronic labor shortages. By the mid-1980s, unemployment had risen...

The Patient Protection and Affordable Care Act (ACA) is the most comprehensive reform of the U.S. medical system in at least 45 years. The ACA transforms the non-group insurance market in the United States, mandates that most residents have health insurance, significantly expands public...

We propose and study properties of several estimators of variance decomposition in the local-projections framework. We find for empirically relevant sample sizes that, after being bias corrected with bootstrap, our estimators perform well in simulations. We also illustrate the workings of our...

The central thesis of this paper is that the management of portfolios incorporating a variety of investment assets does require the use of time and other scarce resources in searching for, collecting, interpreting, and applying relevant information. Accordingly, the returns on these assets would...

We outline a method to provide advice on optimal monetary policy while taking policymakers' judgment into account. The method constructs Optimal Policy Projections (OPPs) by extracting the judgment terms that allow a model, such as the Federal Reserve Board's FRB/US model, to reproduce a...

This paper develops and applies a model of world trade and exchange rates to analyze dynamic interaction of the current account and exchange rate. The model is designed to concentrate on the determination of trade flows, prices and exchange rates for the OECD member countries but it also covers...
