Much recent work has suggested that endogenous technological change tends to reinforce the position of the leading nations. Yet from time to time this leadership role shifts. We suggest a mechanism that explains this pattern of -leapfrogging- as a response to occasional major changes in...

Most of the theoretical literature on price-setting behavior deals with the special case in which only a single price is changed. At the retail-store level, at least, where dozens of products are sold by a single price-setter, price-setting policies are not formulated for individual products....

Economists have long viewed recessions as contributing to increasing inequality. However, this conclusion is largely based on data from a period in which inequality was increasing over time. This paper examines the connection between long-run trends and cyclical variation in earnings inequality....

This paper tackles two established puzzles in international macroeconomics literature. The first is the lack of systematic difference in the macroeconomic performance across exchange rate regimes. The second is the absence of a clear empirical relationship between macroeconomic performance and...

This paper assesses the impact of competition on racial discrimination. The dismantling of inter- and intrastate bank restrictions by U.S. states from the mid-1970s to the mid-1990s reduced financial market imperfections, lowered entry barriers facing nonfinancial firms, and boosted the rate of...

We develop a simple model of international trade with heterogeneous firms that is consistent with a number of stylized features of the data. In particular, the model predicts positive as well as zero trade flows across pairs of countries, and it allows the number of exporting firms to vary...

We disaggregate the self-employed into incorporated and unincorporated to distinguish between "entrepreneurs" and other business owners. We show that the incorporated self-employed and their businesses engage in activities that demand comparatively strong nonroutine cognitive abilities, while...

Banking reforms--that reduced interest rates--boosted college enrollment rates among able students from middle class families. We define "able" students as those with learning aptitude scores in the top two-thirds of the U.S. population. We define "middle class" as families in which both parents...

We study the effects of ability and liquidity constraints on entrepreneurship. We develop a three sector Roy model that differentiates between entrepreneurs and other self-employed to address puzzling gaps that have emerged between theory and evidence on entry into entrepreneurship. The model...

The literature has not being able to identify clear-cut real effects of exchange-rate regimes on output growth. Similarly, no definitive view emerges from the literature in regard to the effects of open capital markets on macroeconomic performance. The paper attributes the failure of the...
