The ``land abundance'' view of African history uses sparse population to explain economic institutions. I provide supporting evidence from the Egba of Nigeria. I use early colonial court records to show that Egba institutions fit the theory's predictions. Before 1914, the Egba had poorly defined...

I show how abundant land and scarce labor shaped African institutions before colonial rule. I present a model in which exogenous land quality and endogenously evolving population determine the existence of land rights, slavery, and polygyny. I use cross-sectional data on pre-colonial African...

Although Nigeria's Benin region was a major rubber producer in 1960, the industry faltered before 1921. I use labor scarcity and state capacity to explain why rubber did not take hold in this period. The government was unable to protect Benin's rubber forests from over-exploitation. Plantations...

African societies exported more slaves in colder years. Lower temperatures reduced mortality and raised agricultural yields, lowering slave supply costs. Our results help explain African participation in the slave trade, which predicts adverse outcomes today. We use an annual panel of African...
