The enlargement of the general-equilibrium structure to allow default subject to penalties results in a construction of a simple mechanism for selecting a unique competitive equilibrium. We consider economies for which a common credit money can be applied to uniquely select any competitive...

The perfectly competitive market - a hypothetical situation free of market failure - serves as a benchmark for economic theory, providing the basis for the two fundamental welfare theorems. The radical abstractions of this idea makes it hard to grasp its full implications, however. In this...

We show by an iterated process of price normalization that there generically exists a price-normalizing bundle that determines a credit money, such that the enlargement of the general-equilibrium structure to allow for default subject to an appropriate credit limit and default penalty for each...

The enlargement of the general-equilibrium structure to allow default subject to penalties results in a construction of a simple mechanism for selecting a unique competitive equilibrium. We consider economies for which a common credit money can be applied to uniquely select any competitive...

In this paper we consider a class of economies with a finite number of divisible commodities, linear production technologies, and indivisible goods, and a finite number of agents. This class contains several well-known economies with indivisible goods and money as special cases. It is shown that...

This paper views uncertainty and economic fluctuations as being primarily endogenous and internally propagated phenomena. The most important Endogenous Uncertainty examined in this paper is price uncertainty which arises when agents do not have structural knowledge and are compelled to make...

This paper establishes a clear connection between equilibrium theory, game theory and social choice theory by showing that, for a well defined social choice problem, a condition which is necessary and sufficient to solve this problem--limited arbitrage--is the same as the condition which is...

In a paper delivered at the December 1955 meeting of the Econometric Society, Paul Samuelson noted that though economists had done "work of high quality and great quantity in the field of taxation," the theory of public expenditure had been "relatively neglected" (1958, 332). Anglo-American...

We use a North-South model with property right differences and resource dynamics to study the effects of trade on resource use and welfare. Autarky is likely to Pareto-dominate free trade in the long run when the environment is quite fragile, and the result is reversed when the environment is...
