We show that the creation of the first integrated pan-European transport network during Roman times influences economic integration over two millennia. Drawing on spatially highly disaggregated data on excavated Roman ceramics, we document that interregional trade was strongly influenced by...

The use of height data to measure living standards is now a well-established method in the economic literature. Moreover, while much is known about 19th century black legal and material conditions, less is known about how 19th century institutional arrangements were related to black stature....

We trace the development of human capital in today's Senegal, Gambia, and Western Mali between 1770 and 1900. European trade, slavery and early colonialism were linked to human capital formation, but this connection appears to have been heterogeneous. The contact with the Atlantic slave trade...

Columbus's arrival in the New World triggered an unprecedented movement of people and crops across the Atlantic Ocean. We study an overlooked part of this Columbian Exchange: the effects of New World crops in Africa. Specifically, we test the hypothesis that the introduction of maize increased...

We develop a model where firms profit from coercing workers into employment under conditions violating national law and international conventions and where bureaucrats benefit from accepting bribes from detected perpetrators. Firms and bureaucrats are heterogeneous. Employers differ in their...

What drives change in a society's values? From Marx to modernization theory, scholars have identified a connection between structural transformation and social change. To understand how changes in a society's dominant mode of production affect its dominant values, we examine the case of the...

Max Weber attributed the higher economic prosperity of Protestant regions to a Protestant work ethic. We provide an alternative theory, where Protestant economies prospered because instruction in reading the Bible generated the human capital crucial to economic prosperity. County-level data from...

Institutions - the structures of rules and norms governing economic transactions - are widely assigned a central role in economic development. Yet economic history is still dominated by the belief that institutions arise and survive because they are economically efficient. This paper shows that...
