A history of the histories of econometrics.

Understanding the history of econometrics as a modern science also asks for understanding of the development of the image of science, which includes the history of philosophy of science and the history of economic methodology. Beside that philosophers of science need to be historically informed, historians of science need to be philosophical informed, which mean more precisely here that they need to be informed about the developments of the philosophical ideas about science. Corry's distinction between the body and image of knowledge does not only provide a framework to write histories of econometrics, but also to write a history of these histories. From its beginnings, econometricians have considered historical knowledge as reflexive knowledge useful to delineate their discipline.econometrics; philosophy of science; discipline

Materials Selection in Economic Modeling

Templates travel because they offer a tractable format that can be used for model-building in a variety of domains. It is often because of this quality that a particular template is chosen. But one cannot assume that there are always templates ready to model a new phenomenon, and moreover, templates have also been designed at some point. A critical aspect of this designing process is the choice of the mathematical objects with which one hopes to capture this phenomenon. This means that one has to assess which of the properties of different kinds of mathematical objects and which combinations of them are most appropriate. The selection of these objects is based on whether their properties enable the model to perform its function. This selection of mathematical objects is similar to the selection of materials in mechanical design

Progress in Economics

In this chapter, we discuss a specific kind of progress that occurs in most branches of economics today: progress involving the repeated use of mathematical models. We adopt a functional account of progress to argue that progress in economics occurs through the use of what we call “common recipes” and model templates for defining and solving problems of relevance for economists. We support our argument by discussing the case of 20th century business cycle research. By presenting this case study in detail, we show how model templates are not only reapplied to different phenomena. We also show how scientists first develop them and how, once they are considered less useful, they are replaced with new ones. Finally, our case also illustrates that it is not only the mathematical structure that is reused but that such reuse also requires a shared conceptual vision of the core properties of the phenomenon to be studied. If that vision is no longer shared among economists, a model template can become useless and has to be replaced, sometimes against resistance, with a different one
