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...

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...
