Settlement delays in the money market
We track 38,000 money market trades from execution to delivery and return to provide a first empirical analysis of settlement delays in financial markets. In line with predictions from recent models showing that financial claims are settled strategically, we document a tendency by lenders to delay delivery of loaned funds until the afternoon hours. We find that banks follow a simple strategy to manage the risk of account overdrafts - delaying the settlement of large payments relative to that of small payments. More sophisticated strategies, such as increasing settlement delays when own liquid ...

Solution of linear-quadratic- Gaussian dynamic games using variational methods
Methods are presented for solving a certain class of rational expectations models, principally those that arise from dynamic games. The methods allow for numerical solution using spectral factorization algorithms and for estimation of these models using maximum likelihood techniques.

Minimally acceptable altruism and the ultimatum game
I suppose that people react with anger when others show themselves not to be minimally altruistic. With heterogeneous agents, this can account for the experimental results of ultimatum and dictator games. Moreover, it can account for the surprisingly large fraction of individuals who offer an even split, with parameter values that are more plausible than those required to explain outcomes in these experiments with the models of Levine (1998), Fehr and Schmidt (1999), Dickinson (2000), and Bolton and Ockenfels (2000).

Games with synergistic preferences
In economic situations a player often has preferences regarding not only his or her own outcome but also regarding what happens to fellow players, concerns that are entirely apart from any strategic considerations. While this can be modeled directly by simply writing down a player's final preferences, these are commonly unknown a priori. In many cases it is therefore both helpful and instructive to explicitly model these interactions. This paper, building on a model due to Bergstrom (1989, 1999), presents a simple structure in the context of game theory that incorporates the "synergies" ...

Custom versus fashion: path-dependence and limit cycles in a random matching game
A pairwise random matching game is considered to identify the social environments that give rise to the social custom and fashion cycles. The game, played by Conformists and Nonconformists, can generate a variety of socially stable behavior patterns. In the path-dependence case, Conformists set the social custom and Nonconformists revolt against it; what action becomes the custom is determined by history. In the limit cycle case, Nonconformists become fashion leaders and switch their actions periodically, while Conformists follow with delay. The outcome depends on the relative share of ...

A beautiful theory
It wasn?t A Beautiful Mind?the book or the movie?that made John Forbes Nash, Jr., famous. It was his work in game theory, a theory that models strategic interactions between people as games. Before Nash, the only games theorists could get a handle on were artificial ones with no real-world applications. Nash?s insights enabled economists to expand the use of game theory to interesting practical problems.

Illiquidity in the interbank payment system following wide-scale disruptions
We show how the interbank payment system can become illiquid following wide-scale disruptions. Two forces are at play in such disruptions-operational problems and changes in participants' behavior. We model the interbank payment system as an n-player game and utilize the concept of a potential function to describe the process by which one of multiple equilibria emerges after a wide-scale disruption. If the disruption is large enough, hits a key geographic area, or hits a "too-big-to-fail" participant, then the coordination of payment processing can break down, and central bank intervention ...
