We show a simple way to introduce monopolistic competition in a general equilibrium model where prices are fully .exible, the velocity of money is variable and cash-in-advance (CIA) constraints occasionally bind.We establish the conditions under which money has real effects and demonstrate that...

Recent empirical evidence suggests that prices for some goods and services are higher in larger markets. This paper provides a demand-side explanation for this phenomenon when firms can choose how much to differentiate their products in a model of monopolistic competition with horizontal product...

We propose a general model of monopolistic competition, which encompasses existing models while being flexible enough to take into account new demand and competition features. Using the concept of Frechet differentiability, we determine a general demand system. The basic tool we use to study the...

This paper discusses a model of vertical and horizontal product differentiation within the Dixit-Stiglitz framework of monopolistic competition. Firms compete not only in prices and horizontal attributes of their products, but also in the quality that can be controlled by R&D activities. Based...

This paper shows that the welfare dominance of ad valorem over unit taxes under imperfect competition, extends to the Dixit-Stiglitz framework with differentiated products, entry and love of variety. This contrasts against findings by Anderson et al. (J Public Econ, 2001) made in a similar...

It is often argued that price indexes do not fully capture the quality improvements of new goods in the market. Because of this shortcoming, price indexes are perceived to overestimate the actual price increases that occur. In this paper, I argue that the quality bias in price indexes is just as...

This paper presents a general-equilibrium model of endogenous skilled-biased technological change and matching unemployment in a disaggregated economy. We simultaneously endogenise both the direction and pace of technological change as well as the unemployment rates. We show that an increase in...

We analyze a generalized neoclassical growth model that combines a normalized CES production function and possible asymmetries of savings out of factor incomes. This generalized model helps to shed new light on a recent debate concerning the impact of factor substitution and income distribution...

In a neoclassical economy with endogenous capital- and labor-augmenting technical change the steady-state growth rate of output per worker is shown to increase in the elasticity of substitution between capital and labor. This confirms the assessment of Klump and de La Grandville (2000) that the...
