The Microfoundations of Macroeconomics: An Evolutionary Perspective

Implicit Microfoundations for Macroeconomics

A large market economy has a huge number of degrees of freedom with weak microlevel coordination. The ‘implicit microfoundations’ approach considers this property of micro-level interactions to more strongly determine macro-level outcomes compared to the precise details of individual choice behavior; that is, the ‘particle’ nature of individuals dominates their ‘mechanical’ nature. So rather th...

The Microfoundations of Macroeconomics

We consider the microfoundations controversy from the perspective of economic evolution and show that the debate can benefit from lessons learned in evolutionary biology. Although the analogy between biology and economics has been noted before, it has rarely focused on clarifying the micro-macro distinction in economic theory and modelling. The macroevolution controversy in biology has generate...

Which Way Forward for Macroeconomics and Policy Analysis?

There was a palpable sense of excitement among the economists who met in Philadelphia in 1969 at the conference organized by Edmund Phelps. Their research over the preceding years had coalesced into a new approach to macroeconomic analysis, one that based macrorelationships on explicit microfoundations. These foundations’ distinctive feature was to accord market participants’ expectations an au...

Disequilibrium macroeconomics: an episode in the transformation of modern macroeconomics

ed from issues they could not handle but which enabled them to analyse the dynamics in which they were interested. However, a more common reaction was to focus on the formal models and to confine their theorizing to what could be said rigorously. Founding macroeconomics on rigorous utilitymaximizing microfoundations was important. This was, no doubt, the reason why Patinkin’s Chapter 13 was neg...
