The game of negotiations: ordering issues and implementing agreements

Along with the rise in income inequality in the U.S., we have observed a simultaneous move toward fiscal devolution and increased government reliance on private provision of public goods. This paper argues that these phenomena are related. We describe a model of jurisdiction and policy formation in which the structure of government provision is endogenous and public good provision levels are determined by a political process that can exploit private motives for voluntary giving. The model predicts that an increase in income inequality leads to decentralization, with local jurisdictions becoming more income-homogeneous than the population as a whole. This reduction in local income heterogeneity, combined with a reduced tax base, results in increased reliance by government on private provision.

Robust nonexistence of equilibrium with incomplete markets

Abstract We construct a pure exchange economy with spot and real security markets for which there does not exist a competitive equilibrium. Moreover, we show that the problem of nonexistence is robust to small perturbations of the endowments of the consumers. The result is driven by a lack of strict convexity of preferences.

Negotiation games with unobservable mixed disagreement actions

Abstract A negotiation model combines an alternating offers bargaining game with a normal form stage game that determines players’ (interim) disagreement payoffs. Busch and Wen [Econometrica 63 (1995) 545] investigated this negotiation model under the assumption that players’ past mixed disagreement actions are observable. The question arises if this assumption is a substantial restriction. In this paper, we adopt the more plausible assumption that only the realizations of past mixed actions are observable, and find that the set of equilibrium payoffs shrinks, compared to that when mixed disagreement actions are observable. We precisely identify the effects of the unobservability and characterize the limiting set of equilibrium payoffs as the two players become sufficiently patient.

Rock Concert Pricing and Anti-Scalping Laws: Selling to an Input

This paper develops a model that jointly explains excess demand for performance events and the presence of anti-scalping laws. The explanation is based on the fact that the buyers of tickets are also an important input into the performance experience. The use of line-ups as a screening mechanism (leading to apparent under-pricing of tickets) can be profit maximizing if the input quality of a given buyer and her willingness to pay for tickets are not sufficiently positively correlated. Such a mechanism is not possible, however, if the resale of tickets above the posted price is permitted. Since resale amounts to input substitution, banning such resale is therefore efficiency enhancing.
