All countries would agree to immediate global free trade if countries were compensated for any terms-of-trade losses with transfers from countries whose terms-of-trade improve, and if customs unions were required to have no effects on non-member countries. Global free trade with transfers is in...

Which issues are discussed by candidates in an election campaign? Why are some issues never discussed? Model tractability is lost quickly when dealing with these questions, partly because of the multidimensional voting inherent in models of multiple issues. Our model features two candidates for...

This paper establishes the existence and efficiency of equilibrium in a local public goods economy with spatial structures by formalizing Hamilton's (1975 Urban Studies) elaboration of Tiebout's (1956 JPE) tale. We use a well-known equilibrium concept from Rothschild and Stiglitz (1976, QJE) in...

Price advertisement by retail stores is pervasive. If there exist non-negligible costs of consumer search, a retailer can increase the number of consumers visiting its location by advertising a low price, thus increasing consumers' expected utilities from search. If the increase in the number of...

We propose a decomposition of social welfare when consumers' preferences are described by quasi-linear utility functions. In our decomposition, social welfare is expressed as the sum of consumers' gross utilities and trade surplus of non-numeraire goods, whose consumption enters utility...

It is known that in two-sided many-to-many matching problems, pairwise-stable matchings may not be immune to group deviations, unlike in many-to-one matching problems (Blair 1988). In this paper, we show that pairwise stability is equivalent to credible group stability when one side has...

It is often argued in the US that HOV (high occupancy vehicle) lanes are wasteful and should be converted to HOT (high occupancy vehicles and toll lanes). In this paper, we construct a simple model of commuters using a highway with multiple lanes, in which commuters are heterogeneous in their...
