A few years back, we wrote a paper pointing out that Solow convergence had finally arrived. The developing world was catching up. Alas, it seems all good things come to an end.

First post is about aid and growth, and what I think is missing from the renewed enthusiasm in DC to subsidize private investment in developing countries: i.e., export discipline.
