Idealization And The Aims Of Economics: Three Cheers For Instrumentalism

Author

Abstract

This paper aims (a) to provide characterizations of realism and instrumentalism that are philosophically interesting and applicable to economics; and (b) to defend instrumentalism against realism as a methodological stance in economics. Starting point is the observation that ‘all models are false’, which, or so I argue, is difficult to square with the realist's aim of truth, even if the latter is understood as ‘partial’ or ‘approximate’. The three cheers in favour of instrumentalism are: (1) Once we have usefulness, truth is redundant. (2) There is something disturbing about causal structure. (3) It's better to do what one can than to chase rainbows.
