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....

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...

Existing theories of pre-emptive war typically predict that the leading country may choose to launch a war on a follower who is catching up, since the follower cannot credibly commit to not use their increased power in the future. But it was Japan who launched a war against the West in 1941, not...

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...

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...

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