We estimate the effect of international trade on average labor productivity at the country level. Our empirical approach relies on summary measures of trade that, we argue, are preferable on both theoretical and empirical grounds to the one conventionally used. In contrast to the marginally...

Many economic booms have been accompanied by real exchange rate appreciations, large trade defcits -which have sometimes persisted after the return to the initial exchange rate parity- and a deteriorating traded sector. Those circumstances have typically raised the question of the de-sirability...

We provide a new perspective on the impact of unauthorized copying and copy levies on artistic creation. Our analysis emphasizes three important aspects of artistic markets: the predominance of superstars, the dynamics of talent sorting, and the importance of promotion expenditures. In the short...

We analyze artistic markets considering three key distinctive features that have been overlooked by the standard analysis on intellectual property. These features are the dynamic link between the current number of young artists and future high-quality artistic creation, Rosen’s superstars...

We provide a new perspective on the impact of unauthorized copying and copy levies on artistic creation. Our analysis emphasizes three aspects of artistic markets: the predominance of superstars, the important role of promotion expenditures, and the difficulties of talent-sorting. In the short...

We analyze the potential trade-off between product variety and consumer information and the implications this trade-off has for product quality. We introduce a simple information accumulation process in a horizontal differentiation model with unobservable quality. As the number of brands...

We find that international trade has an economically significant and statistically robust positive effect on productivity. Our trade measure is imports plus exports relative to purchasing power parity GDP (real openness), which we argue is preferable on theoretical grounds to the nominal measure...

We argue that the role played by output-composition changes on the decline in US output volatility has been incorrectly assessed in the recent literature. We obtain that shifts across broad sectors in the economy account for about thirty-percent of the volatility decline since the 1950’s.

In this paper we develop a common agency model to analyze the problem of pirates entering the market, in which the incumbent and the consumers form pressure groups to lobby the government on policies to prevent piracy while the pirates try to avoid being stopped. We show that a monopoly is not...
