Using the 2003 National Survey of College Graduates, I examine how immigrants perform relative to natives in activities likely to increase U.S. productivity, according to the type of visa on which they first entered the United States. Immigrants who first entered on a student/trainee visa or a...

We provide, for the first time, comparative evidence of the impact of various types of extreme events – natural disasters, terrorism, and violent conflicts – on the perceptions of entrepreneurs concerning some key entrepreneurial issues – such as fear of failure in starting a business...

We utilize county-level data to explore the roles of different types of human capital accumulation in U.S. growth determination. The data includes over 3,000 cross-sectional observations and 39 demographic control variables. The large number of observations provides enough degrees of freedom to...

We consider the role of capital mobility and international taxation in explaining the observed diversity in long-term income growth rates. Under perfect capital mobility, international differences in taxes will not matter for total growth differentials. Policy differences have a role to play in...

Human capital plays an important role in the theory of economic growth, but it has been difficult to measure this abstract concept. We survey the psychological literature on cross-cultural IQ tests, and conclude that modern intelligence tests are well-suited for measuring an important form of a...

We provide an exploratory quantitive analysis of the role of capital mobility and international taxation in explaining the observed cross-country diversity in the long-run rates of growth of per capita and total incomes as well as the population growth rates. Corroborative evidence is found for...

En los últimos años, se han realizado diversos estudios a nivel mundial utilizando el modelo de crecimiento y convergencia económica, a través de países y de regiones. Para el caso de México, hasta la segunda mitad de los noventas comienza el análisis empírico de la convergencia...

I show that in a conventional Ramsey model, between one-fourth and one- half of income differences across countries can be explained by a single factor: The steady-state effect of large, persistent differences in national average IQ on worker productivity. These differences in cognitive...

The paper contains a thorough review of explanations for the weak British growth performance of the 1950s through the 1970s and an assessment of the long-term implications of the 1980s attempt to escape from relative decline. The analysis draws on recent work in growth theory and places...

We develop entrepreneurship and institutional theory to explain variation in different types of entrepreneurship across individuals and institutional contexts. Our framework generates hypotheses about the negative impact of higher levels of corruption, weaker property rights and especially...
