Economic research on structural change in agriculture has repeatedly induced controversies about basic theoretical concepts, such as rational behaviour and equilibrium, and their analytical and political implications. To contribute to the epistemological dimension of this debate, the article gives an overview of three paradigms to economic modelling whose proponents have been inspired by physics, biology, and chemistry. The key concepts of general equilibrium theory, evolutionary economics and the “social chemistry” of Jon Elster are presented and compared. While all keep the idea that intentional individual action can explain aggregate outcomes that are nevertheless unintended, they differ in assumptions concerning preferences and the characteristics of... |

This paper argues that mainstream economics does not follow the positivist research tradition it (often implicitly) claims to follow and expresses some serious doubt that econometrics in particular can make economics a hard science. Mathematical rigour and sophisticated statistical techniques may be regarded as persuasive analytical tools in economics, but their mere application does not guarantee good research practice. The paper outlines an alternative methodological view of pragmatic instrumentalism in which the well known tools of economic analysis can find a new place. Instead of relying on a narrow rule that purports to produce universal truth, this view encourages to increase the target area for questioning and probing. Much more attention is paid... |
