"In advanced economies like the United States, innovation has long been recognized as a central force for increasing socioeconomic prosperity and improving human health. Today, U.S. government policy seeks to promote innovation through a suite of mechanisms, from tax credits in the private...

We study the relationships between corporate R&D and three components of public science: knowledge, human capital, and invention. We identify the relationships through firm-specific exposure to changes in federal agency R\&D budgets that are driven by the political composition of congressional...

We conduct a panel data analysis of 74 countries over 1980 2000 to investigate whether population health affects foreign direct investment inflows. Our main finding is that health has a positive and significant effect on such inflows for low- and middle-income countries. This finding is...

This chapter reviews the recent debate about the role of social capital in economics. We argue that all the difficulties this concept has encountered in economics are due to a vague and excessively broad definition. For this reason, we restrict social capital to the set of values and beliefs...

This paper presents a model where human capital differences - rather than technology differences - can explain several central phenomena in the world economy. The results follow from the educational choices of workers, who decide not just how long to train, but also how broadly. A "knowledge...

An estimated 20 million children born each year are at risk of brain damage from in utero iodine deficiency, the only micronutrient deficiency known to have significant, non-reversible effects on cognitive development. Cognitive damage from iodine deficiency disorders (IDD) has potentially...

Using an endogenous-growth, overlapping-generations framework where human capital is the engine of growth, we trace the dynamic evolution of income and fertility distributions and their interdependencies over three endogenous phases of economic development. In our model, heterogeneous families...

The spectacular growth of the software industry in some non-G7 economies has aroused both interest and concern. This paper addresses two sets of inter-related issues. First, we explore the determinants of these successful stories. We then touch upon the broader question of what lessons, if any,...

We study the consequences of dynamic complementarities in the production of child human capital for the relationship between risk and schooling investment in a low income setting. In contrast to previous literature, we explore the ex ante response of schooling to risk. We develop a model that...

We use international household-survey data to document that experience-wage profiles are flatter in poorer countries than in richer countries. We find a quantitatively similar pattern when we estimate returns to foreign experience by country of origin among U.S. immigrants. The most likely...
