We explain per-capita income gaps across US states and Canadian provinces by the following chain of causation. Geography determined where Europeans originally settled: in Northeastern USA, along those segments of the Atlantic coast where the climate was neither too hot (the US South), nor too...

The institution of slavery is found mostly at intermediate stages of agricultural development, and less often among hunter-gatherers and advanced agrarian societies. We explain this pattern in a growth model with land and labor as inputs in production, and an endogenously determined property...

We present a growth model where agents divide time between rent seeking in the form of resource competition; and working in a human capital sector, interpreted as trade or manufacturing. Rent seeking exerts negative externalities on the productivity of human capital, generating multiple steady...

We construct a model in which a number of equally powerful ethnic groups compete for power by engaging in civil war. In non-redistributive equilibrium, ethnically homogeneous and ethnically diverse countries face a lower probability of civil war than countries with a moderate degree of ethnic...

rates in 18th- and 19th-century Sweden with a seven-grade scale over harvest outcomes in the county where the parish was located. We …find a Malthusian pattern: a good harvest one year leads to lower death rates, and higher birth and marriage rates, in particular the following year; for death...

It may thus serve a ruler’s reproductive interests to be subject to an institution which limits the number of wives he (or anyone who successfully ousts him) can take. Moreover, our model suggests how such marriage norms can arise endogenously in the course of economic development, as an...
