The epsilon-intelligent competitive equilibrium algorithm is a decentralized alternative to Walrus' tatonnement procedure for markets to arrive at competitive equilibrium. We build on the Gode-Spear-Sunder zero-intelligent algorithm in which random generation of bids and offers from agents'...

In a model of asset markets with transaction costs, we find a sufcient condition for an increase in transaction costs to increase buying prices, decrease selling prices, decrease the trading volume, and make all active investors worse off. The sufficient condition is met by all CARA utility...

Collective consumption decisions taken by the members of a household may prove inefficient. The impact of such inefficient household decisions on market performance is investigated. At one extreme, market efficiency can occur even when household decisions are inefficient, namely when household...

We develop an equilibrium model of commodity spot and futures markets in which commodity production, consumption, and speculation are endogenously determined. Speculators facilitate hedging by the commodity suppliers. The entry of new speculators thus increases the supply of the commodity and...

The flow of resources across sectors to their best use, with concomitant entry and exit, is central to the functioning and welfare properties of a market economy. Nevertheless, most industrial organization research, including applications to competition policy, undertakes partial equilibrium...

If consumption takes time, and time is limited, there exists a time constraint in addition to the expenditure constraint of a consumer. This may lead to a form of satiation, where consumers cannot consume all commodities they purchase. We establish existence of competitive equilibrium in the...

Collective consumption decisions taken by the members of a household may prove inefficient. The impact of such inefficient household decisions on market performance is investigated. At one extreme, market efficiency can occur even when household decisions are inefficient, namely when household...

In an exchange economyw ith a finite number of indivisible goods, we analyze a dynamic trading process of coalitional recontracting where agents may make mistakes with small probability. We show first that the recurrent classes of the unperturbed (mistakefree) process consist of (i) all core...

There is a growing body of research in economics that studies the consequences of time-inconsistent preferences. This paper introduces time-inconsistent preferences in a general equilibrium setting. We discuss how the standard notion of competitive equilibrium should be extended in order to...
