Comparative economics for model choice

Abstract

Brosnan and Wilson recently defended a new kind of ‘comparative economics,’ which rests on studies of economic decision-making in non-human animals. What is not yet clear, though, is exactly what role this kind of ‘comparative economics’ can play in economics qua economics. This paper argues that this role consists in constraining economic model choice. ‘Comparative economics’ can point to significant causes that ought to be included in the relevant models, and thus aid the assessment of these models. While this assessment does not guarantee that the identified causes are (the only) significant ones, and while there are also many pragmatic factors that influence model choice, the appeal to insights derived from studies of economic decision-making in non-human animals can still inform the choice among economic models. This also brings to the fore a new role for evolutionary biological considerations in economics, and thus clarifies the methodological foundations of ‘evolutionary economics.’
