One critical aspect of economic development is that productivity growth and a rising standard of living are realized through more roundabout methods of production and increasing specialization of intermediate inputs and producer services. We use an extended version of the Judd-Grossman-Helpman...

Two different models - one based on local geographical externalities and the other on the variety of only locally available intermediate services - are shown to give rise to a simple, estimable relation between employment density and productivity. Using data on gross state output for the U.S.,...

How much would output increase if underdeveloped economies were to increase their levels of schooling? We contribute to the development accounting literature by describing a non-parametric upper bound on the increase in output that can be generated by more schooling. The advantage of our...

We find that over the period 1950-1990, US states absorbed increases in the supply of schooling due to tighter compulsory schooling and child labor laws mostly through within-industry increases in the schooling intensity of production. Shifts in the industry composition towards more...

I document a significant deindustrialization trend in recent decades, that goes considerably beyond the advanced, post-industrial economies. The hump-shaped relationship between industrialization (measured by employment or output shares) and incomes has shifted downwards and moved closer to the...

The contemporary approach to political economy is built around vested interests - elites, lobbies, and rent-seeking groups which get their way at the expense of the general public. The role of ideas in shaping those interests is typically ignored or downplayed. Yet each of the three components...

Africa's recent growth performance has raised expectations of a bright economic future for the continent after decades of decline. Yet there is a genuine question about whether Africa's growth can be sustained, and if so, at what level. The balance of the evidence suggests caution on the...

Much more than comparative advantage and free markets have been at play in shaping China's export success. Government policies have helped nurture domestic capabilities in consumer electronics and other advanced areas that would most likely not have developed in their absence. As a result, China...

There has been a very rapid rise since the early 1990s in foreign reserves held by developing countries. These reserves have climbed to almost 30 percent of developing countries' GDP and 8 months of imports. Assuming reasonable spreads between the yield on reserve assets and the cost of foreign...

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...
