Implicit Microfoundations for Macroeconomics [Dataset]

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 than taking an ‘explicit microfoundations’ approach, in which individuals are represented as ‘white-box’ sources of fully-specified optimizing behavior (‘rational agents’), we instea d represent individuals as ‘black box’ sources of unpredictable noise subject to objective constraints (‘zero-intelligence agents’).

To illustrate the potential of the approach we examine a parsimonious, agent-based macroeconomic model with implicit microfoundations. It generates many of the reported empirical distributions of capitalist economies, including the distribution of income, firm sizes, firm growth, GDP and recessions.
