This paper is structured in three parts. The first part outlines the methodological steps, involving both theoretical and empirical work, for assessing whether an observed allocation of resources across countries is efficient. The second part applies the methodology to the long-run allocation of...

We present two valuation models that we use to account for the annual data on price per share and dividends per share for the CRSP Value-Weighted Index from 1929-2023. We show that it is a simple matter to account for these data based purely on a model of variation in the expected ratio of...

This paper documents, using county level data, some geographical features of the US business cycle over the past 30 years, with particular focus on the Great Recession. It shows that county level unemployment rates are spatially dispersed and spatially correlated, and documents how these...

We study the effect of financial integration (through banks) on the transmission of international business cycles. In a sample of 20 developed countries between 1978 and 2009 we find that, in periods without financial crises, increases in bilateral banking linkages are associated with more...

The 2008-2009 crisis was characterized by an unprecedented degree of international synchronization as all major industrialized countries experienced large macroeconomic contractions around the date of Lehman bankruptcy. At the same time countries also experienced large and synchronized...

Heathcote et al. (2010) conducted an empirical analysis of several dimensions of inequality in the United States over the years 1967-2006, using publicly-available survey data. This paper expands the analysis, and extends it to 2021. We find that since the early 2000s, the college wage premium...

Using a structural life-cycle model and data on school visits from Safegraph and school closures from Burbio, we quantify the heterogeneous impact of school closures during the Corona crisis on children affected at different ages and coming from households with different parental...

The Affordable Care Act (ACA) is one of the most important reforms of the US health insurance system since the introduction of Medicare. Since employment is a main source of health insurance for the working age population in the United States, this sweeping health insurance reform also has...

We analyze efficient risk-sharing arrangements when coalitions may deviate. Coalitions form to insure against idiosyncratic income risk. Self-enforcing contracts for both the original coalition and any deviating coalition rely on a belief in future cooperation, and we treat the contracting...

We show that a calibrated life-cycle two-earner household model with endogenous labor supply can rationalize the extent of consumption insurance against shocks to male and female wages, as estimated empirically by Blundell, Pistaferri and Saporta-Eksten (2016) in U.S. data. In the model, 35% of...
