This paper examines the effects of tax subsidies to employer provided health insurance on the distribution of insurance across firms of different sizes. I present a simple model which shows that the tax subsidies may increase the provision of insurance in smaller firms and hence help equalize...

This study provides causal evidence on the health and economic consequences of a broad-scope vaccination program. The Ontario Influenza Immunization Campaign (introduced in 2001) expanded the scope of vaccine coverage to the full population. By using the timing of this campaign and exogenous...

We construct a new dataset using census, survey, and registry data from hundreds of sources to document a clear positive relationship between development and average establishment size in manufacturing across 134 countries. We rationalize this relationship using a standard model of reallocation...

The relative price of services rises with development. A standard interpretation of this fact is that cross-country productivity differences are larger in manufacturing than in services. The service sector comprises heterogeneous categories. We document that the behavior of relative prices is...

The large differences in income per capita across countries are mostly explained by differences in total factor productivity (TFP). This article summarizes the evidence on the importance of resource allocation across productive units in explaining the observed differences in TFP across countries.

We construct a new dataset using census, survey, and registry data from hundreds of sources to document a clear positive relationship between aggregate productivity and average establishment size for manufacturing establishments across 124 countries. We rationalize this relationship using a...

Consider the following facts. In 1950 the richest ten-percent of countries attained an average of 8 years of schooling whereas the poorest ten-percent of countries attained 1.3 years, a 6-fold difference. By 2005, the difference in schooling declined to 2-fold. The fact is that schooling has...

Consider the following facts. In 1950, the richest countries attained an average of 8 years of schooling whereas the poorest countries 1.3 years, a large 6-fold difference. By 2005, the difference in schooling declined to 2-fold because schooling increased faster in poor than in rich countries....
