This paper presents a unified treatment of and explanation for the evolution of wages and employment in the U.S. over the last 30 years. Specifically, we account for the pattern of changes in wage inequality, for the increased relative wage and employment of women, for the emergence of the...

This paper studies the adoption of nuclear magnetic resonance imaging (MRI) by US hospitals. I consider a timing game of new technology adoption. The dynamic game allows me to take both timing decisions and strategic interaction into account. The model can be solved using standard dynamic...

We study how a continuum of agents learn about disseminated information in a dynamic beauty contest model when they do not observe aggregate variables, such as prices or quantities, but randomly observe each other's actions. We solve for the market equilibrium and find that the average learning...

This paper develops a new way to quantify the effects of import competition on intra-industry patterns of job creation and destruction. It is based on an industrial evolution model with imperfectly competitive product markets, heterogeneous firms, and endogenous entry and exit. First, Colombian...

Central counterparties (CCPs) have increasingly become a cornerstone of financial markets infrastructure. We present a model where CCPs are necessary to implement efficient trade when trades are time-critical, liquidity is limited and there is limited enforcement of trades. We then show that --...

In this paper we consider a number of different ways that a sequence of discrete-time repeated games can approach a continuous-time limit. Our purpose is to clarify the effects of three different factors: 1) The distribution of signals in a fixed discrete-time game, 2) How the distribution (and...

After the fall in fertility during the Demographic Transition, many developed countries experienced a baby bust, followed by the Baby Boom and subsequently a return to low fertility. Received wisdom from the Demography literature links these large fluctuations in fertility to the series of...

This paper analyzes the cross-country allocation and volume of multinational production, quantifies its barriers, and assesses its impact on welfare. From the patterns of multinational production across countries, three facts stand out: a small fraction of country-pairs engages in multinational...

Countries that wish to erect trade barriers have a variety of instruments at their disposal. In addition to tariffs and quotas, countries can offer tax relief, low interest financing, reduced regulation ,and other subsidies to domestic industries facing foreign competition. In a trade agreement,...

We study general equilibrium with nonconvexities. In these economies there exist sunspot equilibria without the usual assumptions needed in convex economies, and they have good welfare properties. Moreover, in these equilibria, agents act as if they have quasi-linear utility. Hence wealth...
