The history of economics as economics?

Abstract
This paper critically evaluates the current decline of the relationship between economics and the history of economics, and proposes a framework called the panorama-cum-scenario model for the practice of the history of economics. Starting with the Hegelian thesis that the history of economics is economics itself, the paper argues that such a relationship is necessary but not sufficient because the history of economics is a metatheory addressed to economic theory. The history of economics needs a panoramic view of the subject and a scenario for the construction, interpretation, and evaluation of the system of economics. The panorama-cum-scenario model enables us to work on the history of economics not only by historical and rational reconstruction but also by global reconstruction. Nietzsche's anti-Hegelian viewpoint and Heidegger's hermeneutical standpoint are useful for identifying the role of historical research in developing economic knowledge based on the panorama-cum-scenario model. Several approaches to the history of economics are examined in light of the panorama-cum-scenario model. Schumpeter's history of economics is interpreted as an example of the panorama-cum-scenario model.
