This paper embeds an oligopolistic industry structure in a real options framework in which synergy gains of horizontal mergers a rise endogenouslya nd vary stochastically over time. We find that(i) mergers are more likely in more concentrated industries; (ii) mergers are more likely inindustries...

One goal of extending the duration of unemployment insurance (UI) in recessions is to increase UI coverage in the face of longer unemployment spells. Although it is a common concern that such extensions may themselves raise nonemployment durations, it is not known how recessions would affect the...

For more than two decades a debate regarding the time-series properties of global and hemispheric temperatures has taken place on the climate change literature and it has hardly been settled at the present time. This paper analyzes the IPCC's AR4 20c3m simulations using modern econometric...

Roy, Falk and Fuller (2004) presented a procedure aimed at providing a test for the value of the slope of a trend function that has (nearly) controlled size in autoregressive models whether the noise component is stationary or has a unit root. In this note, we document errors in both their...

Written in celebration of the 100th anniversary of the American Economic Review, this paper recounts the history of the journal. The recounting has an analytic core that sees the American Economic Association as an organization supplying goods and services to its members, one of which is the...

In this paper I develop a tractable extension of a Mortensen-Pissarides style matching model that allows for risk averse workers with limited ability to smooth consumption.1 I show that this leads to a form of equilibrium wage rigidity. This rigidity arises because the inability of workers to...

This paper uses detailed stroke-by-stroke data from seven tennis Grand Slam tournaments played between 2006 and 2007 to assess whether men and women respond differently to competitive pressure in a setting with large monetary rewards. It finds that at crucial junctures of the match, both men and...

Voluntary standard setting organizations (SSOs) typically require participants to disclose their patents during the standard-setting process, and will endorse a standard only if patent holders commit to license them on “reasonable and non-discriminatory” or RAND terms. We argue that this...

A large body of empirical work documents that prices of traded goods change by a smaller proportion than real exchange rates between the trading countries (incomplete pass-through). The wedge between exchange rates and relative prices also varies a cross countries (pricing-to-market). I present...

We investigate theoretically and empirically the relationship between the geographic structure of a multinational corporation and its risk premium. Our structural model suggests two channels. On the one hand, multinational activity offers diversification benefits: risk premia should be higher...
