This paper develops an approach to measuring the intensity of competition in international markets. The method measures the degree of 'outside' competition faced by exporters located in one source country from firms located outside the source country. We use the elasticity of price and quantity...

Theory predicts that in markets with increasing returns, the number of differentiated products and resulting consumer satisfaction grow in market size. We document this phenomenon across 246 US radio markets. By a mechanism that we term 'preference externalities', an increase in the size of the...

Digital platforms like Uber can enhance market transparency and mitigate moral hazard via ratings of buyers and sellers, real-time monitoring, and low-cost complaint channels. We compare driver choices at Uber with taxis by matching trips so they are subject to the same optimal route. We also...

We consider nonparametric identification in models of differentiated products markets, using only market level observables. On the demand side we consider a nonparametric random utility model nesting random coefficients discrete choice models widely used in applied work. We allow for...

Recent empirical work finds a negative correlation between product market regulation and aggregate employment. We examine the effect of product market regulations on hours worked in a benchmark aggregate model of time allocation. We find that product market regulations affect time devoted to...

In this paper we provide a simple, credible method for assessing the effects of climate change on the quality of agricultural land and then apply this method using a rich set of data on the vineyards of the Mosel Valley in Germany. The basic idea is to use a simple model of solar radiation to...

In recent years, some English critics have claimed that Damien Hirst and his fellow young British artists have made London the new center of the advanced art world. As Hirst reaches the age of 40, this paper uses auction results to measure the importance of the YBAs compared to their American...

Backcasting upward bias in price index over long periods of time yields levels of real consumption two or four centuries ago that are implausibly low, raising the possibility that price index bias for important products may have been zero or even negative at some point in the past. This paper...

Terrorist attacks worldwide during the past several years have spurned an interest in understanding not only how governments can mitigate terrorism risk but also how governments might help finance future losses. This interest was buttressed by the seemingly failure of the private insurance...

This study explores economic aspects of the market for long term care (LTC) with a special focus on Japan. First, we describe the LTC system in Japan as presently implemented, and we highlight some aspects of the program that are novel and potentially of interest to other countries seeking...
