Nominal versus Indexed Debt: A Quantitative Horse Race
By: Laura Alfaro and Fabio Kanczuk
The main arguments in favor of and against nominal and indexed debt are the incentive to default through inflation versus hedging against unforeseen shocks. We model and calibrate these arguments to assess their quantitative importance. We use a dynamic equilibrium... View Details

Competing Complements
By: Ramon Casadesus-Masanell, Barry Nalebuff and David B. Yoffie
In Cournot's model of complements, the producers of A and B are both monopolists. This paper extends Cournot's model to allow for competition between complements on one side of the market. Consider two complements, A and B, where the A + B bundle is valuable only when... View Details

Anger and Regulation
By: Rafael Di Tella and Juan Dubra
We propose a model where voters experience an emotional cost when they observe a firm that has displayed insufficient concern for other people's welfare (altruism) in the process of making high profits. Even with few truly altruistic firms, an equilibrium may emerge... View Details

Optimal Reserve Management and Sovereign Debt
By: Laura Alfaro and Fabio Kanczuk
Most models currently used to determine optimal foreign reserve holdings take the level of international debt as given. However, given the sovereign's willingness-to-pay incentive problems, reserve accumulation may reduce sustainable debt levels. In addition, assuming... View Details

(Noisy) Communication
By: Bharat Anand and Ron Shachar
Communication is central to many settings in marketing and economics. A focal attribute of communication is miscommunication. We model this key characteristic as a noise in the messages communicated, so that the sender of a message is uncertain about its perception by... View Details

A Two-Person Game of Information Transmission
By: Jerry R. Green and Nancy L. Stokey
We consider a statistical decision problem faced by a two player organization whose members may not
agree on outcome evaluations and prior probabilities. One player is specialized in gathering information
and transmitting it to the other, who takes the decision. This... View Details

Correlated Equilibrium and Nash Equilibrium as an Observer's Assessment of the Game
By: John Hillas, Elon Kohlberg and John W. Pratt
Noncooperative games are examined from the point of view of an outside observer who believes that the players are rational and that they know at least as much as the observer. The observer is assumed to be able to observe many instances of the play of the game; these... View Details

Finding Lost Profits: An Equilibrium Analysis of Patent Infringement Damages
By: James J. Anton and Dennis A. Yao
We discuss how a seller can appropriate rents when selling knowledge that lacks legal property rights by solving either an expropriation or a valuation problem and then analyze how seller rents increase when a portion of the intellectual property (IP) can be protected.... View Details

Dynamic Mixed Duopoly: A Model Motivated by Linux vs. Windows
By: Ramon Casadesus-Masanell and Pankaj Ghemawat
This paper analyzes a dynamic mixed duopoly in which a profit-maximizing competitor interacts with a competitor that prices at zero (or marginal cost), with the cumulation of output affecting their relative positions over time. The modeling effort is motivated by... View Details
