Testosterone, which induces sexual differentiation of the male fetus, is believed to transfer from males to their littermates in placental mammals. Among humans, individuals with a male twin have been found to exhibit greater masculinization of sexually dimorphic attributes relative to those...

This paper derives the conditions under which fitness-reducing alleles can survive in a long-run stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction. -- trade ; genotypes ; natural selection ; gene-culture...

The problem with most intergenerational mobility estimates is that unmeasured and inherited abilities prevent us from drawing inferences. In this paper we estimate the intergenerational mobility of schooling and exploit differences between adopted and own birth children to obtain genetically...

We analyze comprehensive manufacturing firm data to measure the contribution of inter-firm employment reallocation to aggregate productivity growth during the socialist and reform periods in six transition economies. Modifying a standard decomposition technique to better reflect the role of firm...

We use longitudinal methods and universal panel data on 30,000 initially state-owned manufacturing firms in four transition economies to estimate the impacts of privatization on employment and wages. The results in all four countries consistently reject job losses and they never imply large wage...

We analyse a three-year panel data set of Russian firms spanning from 2000 to 2002 and we investigate the effect of regional institutional and economic factors on entry rates across time, industries and regions. The paper builds on a novel database and exploits inter-regional variation in a...

During the transition toward a market economy, Russian workers have had to face important structural changes in the labour market as well as dramatic changes in their real earnings. In the process, the wage gap between men and women has varied wildly over that period. In recent years, young...

Alcohol consumption in Russia is legendary and has been reported to be the third leading cause of death in the former Soviet Union after heart disease and cancer. Are Russian alcohol consumers rational addicts? This paper uses eight rounds of a nationally representative Russian survey spanning...

We report evidence from public goods experiments with and without punishment which we conducted in Russia with 566 urban and rural participants of young and mature age cohorts. Russia is interesting for studying voluntary cooperation because of its long history of collectivism, and a huge...
