Propensity to Search and Income Elasticity of Demand: Does the Equilibrium Really Exist?

Abstract

The analysis of the propensity to search under price dispersion discovers the identity of the optimal consumption-leisure choices in the model of optimal search and in the classical model of individual labor supply when the propensity to search is unimportant. However, the vigorous propensity to search, which occurs when consumers visit high-price stores, challenges the classical view on the optimal labor-leisure trade-off. The vigorous propensity to search creates the positive consumption-leisure relationship. The willingness to substitute labor by search under price dispersion also changes the understanding of the income elasticity of demand. The modest propensity to search creates normal but income inelastic demand. The income elastic demand becomes the result of the vigorous propensity to search where consumption-leisure trade-off is positive and either consumption or leisure becomes “bad†. This theoretical assumption proves the occurrence of Veblen effect as well as money illusion and creates doubts in the existence of the general equilibrium.
