The paper examines whether there is a significant relationship between economic growth and the degree of urban concentration, as measured by primacy, or the share of the largest metro area in national urban population. Is there reason to believe many countries have excessive primacy and how...

We provide evidence that the robust association between cognitive skills and economic growth reflects a causal effect of cognitive skills and supports the economic benefits of effective school policy. We develop a new common metric that allows tracking student achievement across countries, over...

This paper examines changes in individual real incomes in South Africa between 1995 and 2000. We document substantial declines--on the order of 40%--in real incomes for both men and women. The brunt of the income decline appears to have been shouldered by the young and the non-white. We argue...

I study data on bribes actually paid by individuals to public officials, viewing the results through a theoretical lens that considers the implications of trust networks. A bond of trust may permit an implicit quid pro quo to substitute for a bribe, which reduces corruption. Appropriate networks...

A unified growth theory is developed that accounts for the roughly constant living standards displayed by world economies prior to 1800 as well as the growing living standards exhibited by modern industrial economies. Our theory also explains the industrial revolution, which is the transition...

In this paper, I examine the role of household income in determining who bribes and how much they bribe in health care in Peru and Uganda. I find that rich patients are more likely than other patients to bribe in public health care: doubling household consumption increases the bribery...

We show that equity market liberalizations, on average, lead to a one percent increase in annual real economic growth over a five-year period. The liberalization effect is not spuriously accounted for by macro-economic reforms and does not reflect a business cycle effect. Although financial...

In 1997-98, five east Asian countries -- Indonesia, Malaysia, South Korea, the Philippines, and Thailand -- experienced sharp currency and banking crises. The contraction of real GDP was severe in relation to the previous history and in comparison with five east Asian countries that were less...

Some natural resources -- oil and minerals in particular -- exert a negative and nonlinear impact on growth via their deleterious impact on institutional quality. We show this result to be very robust. The Nigerian experience provides telling confirmation of this aspect of natural resources....

Entertainment and Travel Costs (ETC) is a standard expenditure item for Chinese firms with an annual amount equal to about 20 percent of total wage bills. We use this objective accounting measure as a basis to analyze the composition of ETC and the effect of ETC on firm performance. We rely on...
