In our evaluation of the housing expenditure share cap, a macroprudential policy, we discover the importance of modeling space. The spatial considerations allow households to sort into segmented housing markets based on income. Our model generates the observed negative relationship between...

This paper examines the role of dual sourcing (e.g., outside options) in vertical and horizontal relations. In a bilateral monopoly market, if either the upstream or downstream firm has outside options, the other firm could lose from seemingly positive shocks, e.g., market expansion or...

We provide a simple theoretical model to explain the mechanism whereby privatization of international airports can improve welfare. The model consists of a downstream (airline) duopoly with two inputs landings at two airports) and two types of consumers. The airline companies compete...

We investigate the effect of banning resale-below-cost offers. There are two retailers with heterogeneous bargaining positions in relation to a monopolistic manufacturer. Each retailer sells two goods: one procured from the monopolistic manufacturer and the other, from a competitive fringe. In...

Using a simple downstream duopoly model with vertical relations and downstream R&D, we investigate the effect of non-assertion of patents (NAP) provisions. A monopoly upstream firm decides whether to employ NAP provisions. If it does so, it freely incorporates the R&D outcomes into its inputs....

This paper examines the role of outside options in a downstream duopoly with exclusive vertical relations as in the Japanese automobile industry. In our setup, the downstream firms have outside options, and two upstream firms with exclusive relations can engage in cost reducing investments. More...

We study the entry timing and location decisions of two exclusive buyer-supplier relationships in a continuous-time spatial competition model. In each relationship, the firms determine their entry timing and location, and negotiate a wholesale price through Nash bargaining. Then, the downstream...

The leading economic explanation for tipping - that is, explanation why the practice is socially beneficial, not why individuals leave tips even though it is not narrowly advantageous to them - is that it confers an incentive to provide personal services. This fits many instances in which...

A seller is selling multiple objects to a set of agents. Each agent can buy at most one object and his utility over consumption bundles (i.e., (object,transfer) pairs) need not be quasilinear. The seller considers the following desiderata for her mechanism, which she terms desirable: (1)...

This paper studies a model of mechanism design with transfers where agents' preferences need not be quasilinear. In such a model, (1) we characterize dominant strategy incentive compatible mechanisms using a monotonicity property; (2) we establish a revenue uniqueness result: for every dominant...
