The average height of children is an indicator for the quality of nutrition and health care. Heights have never declined over longer time spans in Eastern Germany since 1880 - except for the most recent period 1997-2006. In the Eastern German Land of Brandenburg, a data set of 253,050 pre-school...

In this paper we study the quantitative macroeconomic effects of public education spending in USA for the post-war period. Using comparable measures of human and physical capital, from Jorgenson and Fraumeni (1989, 1992a,b), we calibrate a standard dynamic general equilibrium model where human...

We present a dynamic quantitative trade and migration model that incorporates downward nominal wage rigidities and show how this framework can generate changes in unemployment and labor participation that match those uncovered by the empirical literature studying the “China shock.” We find...

We estimate Okun's law, the negative relationship between output and the unemployment rate, at the sector level for the US, the UK, Japan, and Switzerland to test several hypotheses that may explain why the aggregate Okun's coeffcients are different across countries. Specifically, we show that...

This paper investigates regional or international transfers as a means to prevent immigration into unemployment. We analyze a two-country model with free migration in which the rich country is characterized by minimum wage unemployment. Matching grants for investment in infrastructure are...

This paper studies the extent to which the cyclicality of gross and net occupational mobility shapes that of aggregate unemployment and its duration distribution. Using the SIPP, we document the relation between workers' (gross and net) occupational mobility and unemployment duration over the...

The path breaking work of Card and Krueger (1993), showing higher minimum wage can increase employment turned the age-old conventional wisdom on its head. This paper demonstrates that this apparently paradoxical result is perfectly plausible in a competitive general equilibrium production...

Industrial activity periodically experiences breakthrough innovations in energy efficiency, but the estimated impacts of these innovations on aggregate energy use are highly varied. We develop a general equilibrium model to investigate whether this variation is determined by the structure of the...

This paper studies the impact of optimism on occupational choice using a general equilibrium framework. The model shows that optimism has four main qualitative effects: it leads to a misallocation of talent, drives up input prices, raises the number of entrepreneurs, and makes entrepreneurs...
