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...

As poor countries deplete their natural resources, for increased consumption to be sustainable some of the revenues should be invested in other public assets. Further, since such countries typically have acute shortages of public capital, the finance from resource depletion is an opportunity for...

We theoretically and empirically examine the relationship between natural resource revenues and financial development. In the theoretical part, we present a politico-economic model in which contract enforcement is low and decreasing in resource revenues when political institutions are poor, but...

We hypothesize that natural resources raise income inequality in ethnically polarized societies, but reduce income inequality in ethnically homogenous societies; and we present empirical evidence in support of this hypothesis.

This paper investigates the scope for international rules to address market failures in trade in natural resources and the associated international transactions of prospecting and investment in resource exploitation. We argue that several market failures are likely to have substantial costs....

We study how natural resources can feed corruption and how this effect depends on the quality of the democratic institutions. Our game-theoretic model predicts that resource rents lead to an increase in corruption if the quality of the democratic institutions is relatively poor, but not...
