We quantify the impact of scientific grant funding at the National Institutes of Health (NIH) on patenting by pharmaceutical and biotechnology firms. Our paper makes two contributions. First, we use newly constructed bibliometric data to develop a method for flexibly linking specific grant...

We estimate the magnitude of spillovers generated by 112 academic "superstars" who died pre- maturely and unexpectedly, thus providing an exogenous source of variation in the structure of their collaborators' coauthorship networks. Following the death of a superstar, we find that collaborators...

Large gaps in labor productivity between the traditional and modern parts of the economy are a fundamental reality of developing societies. In this paper, we document these gaps, and emphasize that labor flows from low-productivity activities to high-productivity activities are a key driver of...

Unlike economies as a whole, manufacturing industries exhibit unconditional convergence in labor productivity. The paper documents this finding for 4-digit manufacturing sectors for a large group of developed and developing countries over the period since 1990. The coefficient of unconditional...

Using longitudinal survey data collected in collaboration with a treatment program, this paper is the first to estimate the economic impacts of antiretroviral treatment in Africa. The responses in two important outcomes are studied: (1) labor supply of adult AIDS patients receiving treatment;...

This is an attempt to derive broad, strategic lessons from the diverse experience with economic growth in last fifty years. The paper revolves around two key arguments. One is that neoclassical economic analysis is a lot more flexible than its practitioners in the policy domain have generally...

The focus of policy reform in developing countries has moved from getting prices right to getting institutions right, and accordingly countries are increasingly being advised to move towards "best-practice" institutions. This paper argues that appropriate institutions for developing countries...

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 analyze the interplay of policy reform and entrepreneurship in a model where investment decisions and policy outcomes are both subject to uncertainty. The production costs of non-traditional activities are unknown and can only be discovered by entrepreneurs who make sunk investments. The...

Despite its presumed role as an engine of economic growth, we know surprisingly little about the drivers of scientific creativity. In this paper, we exploit key differences across funding streams within the academic life sciences to estimate the impact of incentives on the rate and direction of...
