Ideological debates on the role of government in development have focused on two contrasting prescriptions: one calling for large scale government interventions to solve problems of massive market failures, the other for the unfettering of markets, with the dynamic forces of capitalism naturally...

This paper explores the implications for less developed countries the hypothesis that workers' productivity depends on the wages they receive. In particular, we show that this hypothesis may explain the high urban wages and unemployment found in many such countries. The market equilibrium is...

Progress in artificial intelligence and related forms of automation technologies threatens to reverse the gains that developing countries and emerging markets have experienced from integrating into the world economy over the past half century, aggravating poverty and inequality. The new...

This paper explores the causes and consequences of the more important market failures which impede the development of LOCs, and explains why the non-market institutions which often ameliorate the effects of market failures in developed countries are less effective- in doing so in LOCs. This...

This paper analyzes the role of real exchange rate (RER) policies in promoting economic development. Markets provide a suboptimal amount of investment in sectors characterized by learning spillovers. We show that a stable and competitive RER policy may correct for this externality and other...

Medical and public health innovations in the 1940s quickly resulted in significant health improvements around the world. Countries with initially higher mortality from infectious diseases experienced greater increases in life expectancy, population, and - over the following 40 years - social...
