Beyond the Representative Agent (Hardback)

This challenging book extends standard economic theory to take into account the presence of heterogeneity among economic agents. It argues for an approach to economic analysis which regards the economy as an interactive system with heterogeneous agents and not simply a system which treats aggregates as some 'representative' individual. The authors consider that no sector of the economy can be treated as behaving like a single individual and each sector should be modelled as a complex interactive system. They apply this approach to many macro- and micro- analyses including monetary policy and firms, technological innovation and the insider-outsider model. In conclusion the authors find that this approach proves much more fruitful in explaining empirical phenomena than much of the existing theory. The result of this approach to economic theory which encompasses many realistic features, provides a vision of the economy which is not at odds with common sense, but which does not abandon rigorous analysis. This important book will be welcomed by those interested in both macro and micro economic theory.
