As the world's telecommunication providers privatize, governments turn toward regulatory mechanisms to resolve interconnection disputes. Following provisions of the World Trade Organization agreement, these decisions are supposed to be decided on the basis of "cost;" however, the language...

A model of city formation and evolution is elaborated, based on a multi-agent model of endogenous firm formation. Agents have heterogeneous abilities, are boundedly rational, and interact directly with one another out of equilibrium in team production environments. Each agent works in a firm and...

The paper develops a theoretical model of endogenous wealth distribution, showing that a logarithmic mean constraint in the maximum entropy formalism leads to a power law distribution. On the level of economic theory, the model implies two trade-offs: first, the higher the aggregate growth of...

We examine the effects of decreasing down payment requirements on consumption volatility within a model which generalizes the standard buffer-stock model of saving to accommodate durables, nondurables and a collateralized liquidity constraint. We consider both a version of the model without...

There is by now a large literature characterizing conditions under which learning schemes converge to rational expectations equilibria (REEs). A number of authors have claimed that these results are dependent on the assumption of homogeneous agents and homogeneous learning. We study the local...

This paper investigates private-value `reserve price' auctions when there is a strong bidder in an n-bidder model. Consider an auction model, in which bidders draw their values from the same distribution, but then identity of the high-value bidder is revealed. This can be more plausible than the...

In this paper, we describe a numerical method to price barrier options on a zero-coupon bond. The method can be applied to one-factor short rate models where the transtion distribution function of the short rate is known and no explicit solutions for barrier bond options are available. We give...

This paper uses computational techniques to explore the relationship between trade and war. It develops and simulates an agent-based model in which trade and military conflict are emergent processes within a system of states. The model explores different initial configurations, and the economic...

Krylov subspace methods have proven to be powerful methods for solving sparse linear systems arising in several engineering problems. More recently, these methods have been successfully applied in computational economics, for instance in the solution of forward-looking macroeconometric models...

Since the beginning of this century, the normal distribution has played a central role in the mathematical finance literature. However, major drawbacks insight this assumption rely in the absence of closed form expressions for both its cumulative and probability density functions. Additionally,...
