European empires had two key economic aspects: the extraction of colonial wealth by colonizers, and the relevance of trade for the colonial economies. I build a simple model of decolonization that puts these two elements at centre stage. By controlling policy in the colony, the mother country...

I construct a theory of foreign interventions in which the preferences of the foreign country over alternative local groups are determined by each group's international economic ties. In equilibrium, the foreign country supports the group with which it has the strongest ties, since this is most...

Mine-related transport infrastructure specializes in connecting mines to the coast, and not so much to neighboring countries. This is most clearly seen in developing countries, whose transport infrastructure was originally designed to facilitate the export of natural resources in colonial times....

This paper studies the role played by politics in shaping the Italian railway network, and its impact on long-run growth patterns. Examining a large state-planned railway expansion that took place during the second half of the 19th century in a recently unified country, we first study how both...

Colonial trade encouraged the colonies to specialise in primary products. Did this prevent in-dustrialisation in the colonies? And did lack of industrialisation, in turn, help to keep the colonies under control? To answer these questions, we examine the impact of the temporary collapse in trade...

Africa's interior-to-coast roads are well suited to export natural resources, but not to support regional trade. Are they the optimal response to geography and comparative advantage, or the result of suboptimal political distortions? We investigate the political determinants of road paving in...

Empirical studies have uncovered an inverted-U relationship between product-market competition and innovation. This is inconsistent with the original Schumpeterian Model, where greater competition reduces the profitability of innovation. We show that the model can predict the inverted-U if the...
