The purpose of this note is to demonstrate a sufficient condition for discrete tâtonnement process to lead to chaos in a general equilibrium model with multiple commodities. The result indicates that as the speed of price adjustment increases the discrete tâtonnement process is complex in a general equilibrium economy in which there are multiple equilibria.

the aim of this paper is to investigate the existence of the new non-ricardian regime policy in iranian economy. we detected signs of the non-ricardian regime from quarterly data of 1369 to 1391. to investigate further a dynamic stochastic general equilibrium model is designed to estimate the fiscal and monetary parameters using a bayesian approach. our results indicated a passive monetary poli...

This paper presents a general model of an exchange economy with consumption externalities, and establishes the existence of equilibrium in the model, under assumptions comparable to those in classical models. The key aspect of the model is that the economy is described in distributional terms. JEL Classification D5

This chapter is a simple, rigorous, practically-oriented exposition of computable general equilibrium (CGE) modeling. The general algebraic framework of a CGE model is developed from microeconomic fundamentals, and employed to illustrate (i) how a model may be calibrated using the economic data in a social accounting matrix, (ii) how the resulting system of numerical equations may be solved for...

This paper provides a simple dynamic optimization model of durable goods inventories. Closed-form solutions are derived in a general equilibrium environment with imperfect information and serially correlated shocks. The model is then applied to scrutinize some popular conjectures regarding the causes of the volatility reduction of GDP since 1984. JEL Classification: E22, E23, E32.

A large economic literature discusses the implications of export sanctions for a variety of states around the world. This paper investigates the macro-level consequences of imposing oil export barriers on an oil exporting country. We employ a large real financial computable general equilibrium for Iran. The model is calibrated based on 1999 Social Accounting Matrix for the economy of Iran inc...

Commodity money arises endogenously in a general equilibrium model with separate budget constraints for each transaction. Transaction costs imply differing bid and ask (selling and buying) prices. The most liquid good—with the smallest proportionate bid/ask spread—becomes commodity money. General equilibrium may not be Pareto efficient. If zero-transaction-cost money is available then the equil...

This paper assesses the economic impacts of the Swiss climate policy formulated under the Kyoto Protocol; the impacts on the carbon price, the welfare cost, and trade effects are examined. Our analysis is based on a multi-sectoral and multi-regional, computable general equilibrium (CGE) model of the world economy (GEMINI-E3) which includes a representation of the Swiss economy. The model is use...

We introduce a maximum entropy approach to parameter estimation for computable general equilibrium (CGE) models. The approach applies information theory to estimating a system of nonlinear simultaneous equations. It has a number of advantages. First, it imposes all general equilibrium constraints. Second, it permits incorporation of prior information on parameter values. Third, it can be applie...
