We construct an endogenous growth model that includes a cultural variable along the dimension of individualism-collectivism. The model predicts that more individualism leads to more innovation because of the social rewards associated with innovation in an individualist culture. This cultural effect may offset the negative effects of bad institutions on growth. Collectivism leads to efficiency gains relative to individualism, but these gains are static, unlike the dynamic effect of individualism on growth through innovation. Using genetic data as instruments for culture we provide strong evidence of a causal effect of individualism on income per worker and total factor productivity as well as on innovation. The baseline genetic markers we use are interpreted as proxies for cultural transmi...

We investigate the impact of U.S. bombing on later economic development in Vietnam. The Vietnam War featured the most intense bombing campaign in military history and had massive humanitarian costs. We use a unique U.S. military dataset containing bombing intensity at the district level (N=584). We compare the heavily bombed districts to other districts controlling for baseline demographic characteristics and district geographic factors, and use an instrumental variable approach exploiting distance to the 17th parallel demilitarized zone. U.S. bombing does not have a robust negative impact on poverty rates, consumption levels, infrastructure, literacy or population density through 2002. This finding suggests that local recovery from war damage can be rapid under certain conditions, althoug...

We present a theoretical model of a parliamentary democracy, where party structures, government coalitions and fiscal policies are endogenously determined. The model predicts that, relative to proportional elections, majoritarian elections reduce government spending because they reduce party fragmentation and, therefore, the incidence of coalition governments. Party fragmentation can persist under majoritarian rule if party supporters are unevenly distributed across electoral districts. Economic and political data, from up to 50 post-war parliamentary democracies, strongly support our joint predictions from the electoral rule, to the party system, to the type of government, and to government spending.
