We investigate and compare countries' export growth based on their performance at the extensive and intensive export margins. Our empirical approach is motivated by an extension to the Melitz (2003) model of heterogeneous firms in which exporters are subject to a one-time sunk cost and also a...

This paper revisits and critically reevaluates the widely-accepted modernization hypothesis which claims that per capita income causes the creation and the consolidation of democracy. We argue that existing studies find support for this hypothesis because they fail to control for the presence of...

A model is proposed to describe the evolution of real GDPs in the world economy that is intended to apply to all open economies. The five parameters of the model are calibrated using the Sachs-Warner definition of openness and time-series and cross-section data on incomes and other variables...

The paper documents the large cross-country differences in labor institutions that make them a candidate explanatory factor for the divergent economic performance of countries and reviews what economists have learned about the effects of these institutions on economic outcomes. It identifies...

While the economies of the fifteen countries that were in the European Union (EU15) in 2000 will continue to grow from now until 2040, they will not be able to match the surges in growth that will occur in South and East Asia. In 2040, the Chinese economy will reach $123 trillion, or nearly...

We explore the question of how political institutions and particularly democracy affect economic growth. Although empirical evidence of a positive effect of democracy on economic performance in the aggregate is weak, we provide evidence that democracy influences productivity growth in different...

We estimate the effect of political regime transitions on growth with semi-parametric methods, combining difference in differences with matching, that have not been used in macroeconomic settings. Our semi-parametric estimates suggest that previous parametric estimates may have seriously...

We develop a model of investment with financial constraints and use it to investigate the relation between investment and Tobin's q. A firm is financed partly by insiders, who control its assets, and partly by outside investors. When their wealth is scarce, insiders earn a rate of return higher...

This paper identifies factors associated with takeoff -- a sustained period of high growth following a period of stagnation. We examine a panel of 241 "stagnation episodes" from 146 countries, 54 % of these episodes are followed by takeoffs. Countries that experience takeoffs average 2.3% annual...

This paper presents and critically discusses a vast array of evidence on the determinants of mortality reductions in developing countries. We argue that increases in life expectancy between 1960 and 2000 were largely independent from improvements in income and nutrition. We then characterize the...
