Explanatory value in context: the curious case of Hotelling’s location model

Abstract

There is a striking contrast between the significance of Harold Hotelling’s contribution to industrial economics and the fact that his location model was invalid, unrealistic and non-robust. It is difficult to make sense of the explanatory value of Hotelling’s model based on philosophical accounts that emphasize logical validity, representational adequacy, and robustness as determinants of explanatory value. However, these accounts are misleading because they overlook the context within which the explanatory value added of a model is apprehensible. We present Hotelling’s model in its historical context and show why it is an important and explanatory model despite its apparent deficiencies. © 2020 Elsevier B.V., All rights reserved.
