This paper studies how the prehistoric geographic distribution of domesticable transport animal species has contributed to shaping differences in development. I identify the historic ranges of the ten animal species that are (1) suitable for domestication and (2) suitable for carrying loads....

Anthropologists have long documented substantial and persistent differences across social groups in the preferences and taboos for particular foods. One natural question to ask is whether such food cultures matter in an economic sense. In particular, can culture constrain caloric intake and...

This research explores the origins of the distribution of time preference across regions. It advances the hypothesis, and establishes empirically that geographical variations in the natural return to agricultural investment have had a persistent effect on the distribution of time preference...

This research explores the effects of culture on technological diffusion and economic development. It shows that culture's direct effects on development and barrier effects to technological diffusion are, in general, observationally equivalent. In particular, using a large set of measures of...

This paper analyses the connection between legal origins and generalized trust. Based on recent results of institutions and trust research it argues that legal origins and trust are connected via the beliefs of agents. Next, it develops hypotheses about a complex and self-reinforcing causal...

Do legal institutions affect norms of cooperation? Using the introduction of the Code Napoleon during the Napoleonic Wars in Germany as a historical experiment, I show that a positive shock to the quality of legal institutions can increase social-capital long-lastingly. I find that individuals...

This research explores the effects of within-group heterogeneity on group-level productivity. It establishes that observed genetic diversity of 230 worldwide ethnic groups, as well as predicted genetic diversity of 1,331 ethnic groups across the globe, has a hump-shaped effect on economic...
