Monopolistic Competition, As You Like It

Abstract

We study monopolistic competition with asymmetric preferences over a variety of goods provided by heterogeneous firms, and show how to compute equilibria through the Morishima measures of substitution. Further results concerning pricing and entry emerge under homotheticity and when demands depend on common aggregators, as for Generalized Additively Separable preferences (encompassing additive, Gorman-Pollak and implicit CES preferences). We discuss selection effects of changes in aggregate productivity, expenditure and market size, and present applications to trade, with markups variable across goods, and macroeconomics, with markups depending on aggregate variables.
