A general and practical competitive market model for trading indivisible goods is introduced. There are a group of buyers and a group of sellers, and several indivisible goods. Each buyer is initially endowed with a sufficient amount of money and each seller is endowed with several units of each...

We present a simple general-equilibrium model where one industry is oligopolistic and vertically differentiated. The manufacturing of products of a higher quality requires the employment of a larger amount of skilled labour. Given an underlying skills distribution, the model determines profits,...

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...

A multisectoral dynamic general equilibrium tax model with and without announcement effects for open and closed capital markets is used to evaluate efficiency gains and transitional effects from equal yield tax reforms for seven different taxes in the UK economy. Impacts of an unanticipated tax...

As worked out a century ago, the neoclassical theory of distribution was analytically as well as ideologically satisfying. The simultaneous determination of input and output prices through the operation of factor and product markets seemed to close the explanatory gap left by the classical...

We extend the standard model of general equilibrium with incomplete markets to allow for default and punishment by thinking of assets as pools. The equilibrating variables include expected delivery rates, along with the usual prices of assets and commodities. By reinterpreting the variables, our...

Conventional deadweight loss measures of the social cost of monopoly ignore, among other things, the social cost of inducing competition and thus cannot accurately capture the loss in social welfare. In this Article, we suggest an alternative method of measuring the social cost of monopoly....

Age structured populations are studied in economics through overlapping generations models. These models allow for a realistic characterization of life-cycle behaviors and display intertemporal equilibrium that are not necessarily efficient. This article uses the latest developments in...

The goal of this paper is to provide an investigation of several approaches to valuing ecosystem services and to contribute additional techniques which may be used in evaluating `green' GDP accounts. Our estimates focus on the ecosystem as a productive economic input, not a stock which is...

The welfare costs of dynamic factor taxes are analyzed in a dynamic general equilibrium model with heterogeneous endowments, abilities, and tastes. Conventional functional form restrictions yield formulas for the transition effects and marginal welfare costs of factor taxes. Heterogeneity...
