We build a model of optimal fixed-rate mortgage refinancing with fixed costs and inattention and derive a new sufficient statistic that can be used to measure inattention frictions from simple moments of the rate gap distribution. In the model, borrowers pay attention to rates sporadically so...

This paper develops an algorithm for analyzing discrete events, such as labor market transitions, when some of these transitions are spurious because of measurement errors. Our algorithm extends the standard multinomial logit model, although our basic approach could be used with other stochastic...

There are two possible reasons for unionized workers to have lower quit rates than otherwise comparable nonunion workers: unions could organize employees with innately lower propensities to quit or they could reduce propensities by offering disgruntled workers alternatives to quitting in the...

Network planning models, which forecast the profitability of airline schedules, support many critical decisions, including equipment purchase decisions. Network planning models include an itinerary choice model that is used to allocate air total demand in a city pair to different itineraries....

The North Dakota Railroad War of 1905, which pitted a potential entrant (the Soo Line) against an established monopolist incumbent (the Great Northern Railway), offers a lucid empirical example of strategic behavior, and in particular the potential for entry deterrence through product...

The real economic cost of homeownership depends on an intricate system of taxes and subsides that vary over time and across the United States. We incorporate the key features of this system into a framework for measuring the annual user-cost of housing and we use it to document how housing costs...

Commercial real estate accounts for roughly 20% of the U.S. fixed asset stock, and commercial land use is highly regulated. However, little is known about the quantitative impact of these regulations on economic activity or consumer welfare. This paper develops a spatial general equilibrium...

This paper introduces consumption segregation, a new margin of residential segregation, and examines its patterns, causes, and discusses its aggregate consequences. We use new longitudinal and highly granular data to measure consumption segregation in the United States and document that it is...

How does the interplay of geography and political-economic forces affect the shape of nations? This paper presents a quantitative framework for characterizing the equilibrium evolution of national boundaries in a world with a rich geography. The framework delivers simple equilibrium conditions...
