Modelling Complementarity in Monopolistic Competition

Abstract

In recent years, monopolistic competition models have frequently been applied in macroeconomics, international and interregional economics, and economic growth and development. In this paper, I present a highly selective review in this area, with special emphasis on complementarity and its role in generating multiplier processes, agglomeration, underdevelopment traps, regional disparities, and sustainable growth or, more generally, what Myrdal (1957) called the "principle of circular and cumulative causation."
