Abstract

This paper defends the viability of de-idealization strategies in economic modeling against recent criticism. De-idealization occurs when an idealized assumption of a theoretical model is replaced with a more realistic one. Recently, some scholars have raised objections against the possibility or fruitfulness of de-idealizing economic models, suggesting that economists do not employ this kind of strategy. We present a detailed case study from the theory of industrial organization, discussing three different models, two of which can be construed as de-idealized versions of the first (the so-called Bertrand model of oligopoly). We conclude that recent pessimism about de-idealization in economics is largely unfounded, and that de-idealization strategies are not only possible but also widely employed in economics.

经济建模中的去理想化辩护：一个案例研究

针对最近的批评，本文为经济建模中去理想化策略的可行性进行了辩护。当理论模型的理想化假设被更现实的假设取代时，就会发生去理想化。最近，一些学者对去理想化经济模型的可能性或成果提出了反对意见，认为经济学家没有采用这种策略。我们从产业组织理论中提出了一个详细的案例研究，讨论了三种不同的模型，其中两种可以被解释为第一种（所谓的寡头垄断的Bertrand模型）的去理想化版本。我们得出的结论是，最近经济学中对去理想化的悲观情绪在很大程度上是没有根据的，去理想化策略不仅是可能的，而且在经济学中广泛应用。

期刊介绍： For more than four decades Philosophy of the Social Sciences has served as the international, interdisciplinary forum for current research, theory and debate on the philosophical foundations of the social services. Philosophy of the Social Sciences focuses on the central issues of the social sciences, including general methodology (explaining, theorizing, testing) the application of philosophy (especially individualism versus holism), the nature of rationality and the history of theories and concepts. Among the topics you''ll explore are: ethnomethodology, evolution, Marxism, phenomenology, postmodernism, rationality, relativism, scientific methods, and textual interpretations. Philosophy of the Social Sciences'' open editorial policy ensures that you''ll enjoy rigorous scholarship on topics viewed from many different-- and often conflicting-- schools of thought. No school, party or style of philosophy of the social sciences is favoured. Debate between schools is encouraged. Each issue presents submissions by distinguished scholars from a variety of fields, including: anthropology, communications, economics, history, linguistics, philosophy, psychology, and sociology. Each issue brings you in-depth discussions, symposia, literature surveys, translations, and review symposia of interest both to philosophyers concerned with the social sciences and to social scientists concerned with the philosophical foundations of their subjects.
