In thinking about policy, academic economists alternate between theoretical models in which governments can design finely-tuned optimal interventions and practical considerations which usually assume the government to be incompetent and hostage to special interests. I argue in this paper that...

Do countries with lower policy-induced barriers to international trade grow faster, once other relevant country characteristics are controlled for? There exists a large empirical literature providing an affirmative answer to this question. We argue that methodological problems with the empirical...

This study focuses on the role of trade and trade policy in achieving sustained long-term growth in Africa. One major conclusion is that trade policy in Sub-Saharan Africa works much the same way that it does elsewhere. High levels of trade restrictions have been an important obstacle to exports...

The export booms in South Korea and Taiwan starting in the early 1960s are anomalous when compared with later export booms in other, non-East Asian countries such as Chile and Turkey. First, these booms have taken place in the context of comparatively small changes in relative prices in favor of...

Despite the well-known gains from trade, trade liberalization is politically one of the most contentious actions that a government can take. We propose and formalize a new argument, having to do with uncertainty, which is complementary to the usual explanations for why that is the case; many...

We estimate the respective contributions of institutions, geography, and trade in determining income levels around the world, using recently developed instruments for institutions and trade. Our results indicate that the quality of institutions trumps' everything else. Once institutions are...

We consider a model of policy choice in which appropriate policies depend on a country's own circumstances, but the presence of a successful leader generates an informational externality and results in too little 'policy experimentation.' Corrupt governments are reined in while honest...

This paper argues that domestic social conflicts are a key to understanding why growth rates lack persistence and why so many countries have experienced a growth collapse after the mid-1970s. It emphasizes conflicts interact with external shocks on the one hand, and the domestic institutions of...
