Welfare effects of demand management policies: Impact multipliers under alternative model structures

Abstract

This paper explores the sensitivity of multiplier estimates under three alternative assumptions about factor supply. For this purpose, we have used a general equilibrium model of Malaysia which allows endogenous determination of factor and output prices and which permits substitution in both production and demand in response to price. The structure of the model and three alternative factor supply assumptions under which the model can be solved are described. These alternative assumptions amount to alternative “closure rules.” The results of a general increase in demand as estimated under each of the alternative closures are then presented. Finally, we examine the results of two specific types of demand increase under each of the closure rules, focusing especially upon welfare related variables such as real household consumption levels.
