Cambridge Working Papers in Economics from Faculty of Economics, University of Cambridge

Abstract: This chapter provides a selective survey of recent developments in the study of social welfare under oligopoly. The main topics covered are (i) the rate of cost pass through as a tool to analyze market performance; (ii) the quantification of welfare losses due to market power in Cournot-style models; and (iii) new results from models with endogenous entry. The chapter highlights common themes across these topics and identi.es areas for future research.
