This chapter is concerned with numerical simulation of dynamic economic models. We focus on some basic algorithms and study their accuracy and stability properties. This analysis is useful for an optimal implementation and testing of these procedures, as well as to evaluate their performance....

In economics the main efficiency criterion is that of Pareto-optimality. For problems of distributing a social endowment a central notion of fairness is no-envy (each agent should receive a bundle at least as good, according to her own preferences, as any of the other agent's bundle). For most...

Fishburn (1970) showed that in an infinite society Arrow's axioms for a preference aggregation rule do not necessarily imply a dictator. Kirman and Sondermann (1972) showed that, in this case, nondictatorial rules imply an invisible dictator that, whenever the agent set is an atomless finite...

In an influential article, Alesina and Drazen (1991) model delay of stabilization as the result of a struggle between political groups supporting reform plans with different distributional implications. In this paper we show that ex ante asymmetries in the costs of delay for the groups will...

In this paper I inquire about the effects initial wealth has on black-white differences in early employment careers. I set up a dynamic model in which individuals simultaneously search for a job and accumulate wealth, and fit it to data from the National Longitudinal Survey (1979-cohort). The...

This paper analyzes cheap talk in an investment model with information externalities. In contrast to Gossner and Melissas (2006), I allow for (i) competition effects, (ii) positive network externalities and (iii) more than one interviewed player. In the presence of competition effects, a player...

We analyze how the entry of less informed participants in a market for a risky asset affects the volatility of the price of the asset. In an endogenous participation model, we show that in equilibrium the new market entrants are less informed than the rest of the participants. We study how...

I study a game in which two players first bid for offshore tracts (below which oil and gas may be present) and next time their drilling decisions. High types bid more aggressively if the auctioneer discloses bids as this gives them useful information about the profitability of drilling. A low...

This paper develops a quantitative model of unsecured debt, default, and money demand for heterogenous agents economies. The paper generates a theory of money demand for the case in which money is a dominate asset that is not needed to carry-out transactions. In this environment holding money...

In Internet auctions bidders frequently bid in one of three ways: either only early, or late, or they revise their early bids. This paper rationalizes all three bidding patterns within a single equilibrium. We consider a model of a dynamic auction in which bidders can search for outside prices...
