We study cross-country insurance in a currency union with nominal price and wage rigidities. We provide two results that build the case for the creation of a fiscal union within a currency union. First, we show that, if financial markets are incomplete, the value of gaining access to any given...

It has been suggested that countries which export in especially risky sectors will experience higher output volatility. This paper develops a measure of the riskiness of a country's pattern of export specialization, and illustrates its features across countries and over time. The exercise...

This paper integrates in a unified and tractable framework some of the key insights of the field of international trade and economic growth. It examines a sequence of theoretical models that share a common description of technology and preferences but differ on their assumptions about trade...

What is the role of transport improvements in globalization? We argue that the nineteenth century is the ideal testing ground for this question: freight rates fell on average by 50% while global trade increased 400% from 1870 to 1913. We estimate the first indices of bilateral freight rates for...

We study the effect of a firm winning an additional H-1B visa on the firm’s outcomes, by comparing winning and losing firms in the Fiscal Year 2006 and 2007 H-1B visa lotteries. We match administrative data on the participants in these lotteries to the universe of approved U.S. patents, and to...

Firms in the same industry can differ in measured productivity by multiples of 3. Griliches (1957) suggests one explanation: the quality of inputs differs across firms. We add labor market history variables such as experience and firm and industry tenure, as well as general human capital...

In search and bargaining models, the effect of higher wages on employment is determined by the elasticity of the job creation curve. In this paper, we use U.S. data over the 1970-2007 period to explore whether labor market outcomes abide by the restrictions implied by such models and to evaluate...

This paper asks whether startups react more to changing investment opportunities than more mature firms do. We use the fact that a region's pre-existing industrial structure creates exogenous variation in the severity of its exposure to nation-wide manufacturing shocks to develop an instrument...

The voluminous literature on minimum wages offers little consensus on the extent to which a wage floor impacts employment. We argue that the minimum wage will impact employment over time, through changes in growth rather than an immediate drop in relative employment levels. We conduct...

We juxtapose the effects of trade and technology on employment in U.S. local labor markets between 1990 and 2007. Labor markets whose initial industry composition exposes them to rising Chinese import competition experience significant falls in employment, particularly in manufacturing and among...
