Positivism about Economics

Economists associated with the Austrian School of Economics are known to deny the value of macroeconomics as descended from the work of John Maynard Keynes and, especially, his followers. Yet, Austrian economists regularly engage in a related scientific activity: theorizing about the causes and consequences of economic fluctuations, i.e., the business cycle. What explains the Austrians’ willingness to engage in theorizing about the business cycle while denying the scientific import of macroeconomics? The present paper argues that the methodological precepts of (...) the School, which have remained largely in place since Carl Menger first pronounced them at the start of the Methodenstreit, justify the kind of business-cycle theorizing that Austrians do and imply the limited scientific value of macroeconomics as descended from Keynes.

Should economics study the psychological basis of agents' choice behaviour? I show how this question is multifaceted and profoundly ambiguous. There is no sharp distinction between "mentalist'' answers to this question and rival "behavioural'' answers. What's more, clarifying this point raises problems for mentalists of the "functionalist'' variety (Dietrich and List, 2016). Firstly, functionalist hypotheses collapse into hypotheses about input--output dispositions, I show, unless one places some unwelcome restrictions on what counts as a cognitive variable. Secondly, functionalist hypotheses make some (...) risky commitments about the plasticity of agents' choice dispositions. (shrink)

En la segunda mitad del siglo XIX la filosofía positiva se consolidó como la corriente de pensamiento dominante en México, muchos pensadores la utilizaron como marco teórico para interpretar los acontecimientos pasados y proyectar elfuturo de la nación. Por su análisis, explicación e interpretación de la historia nacional México: su evolución social es la obra culminante del positivismo mexicano, pero para sorpresa nuestra ha sido poco estudiada por los especialistas, de ahí que sea necesario recuperarla. En este artículo nos damos (...) a esa tarea y para ello nos enfocaremos en analizar el método de investigación que emplea la obra así como el papel que cumple la historia dentro de la misma. Con ello se busca contribuir a los estudios sobre el positivismo mexicano al abordar, en una obra crucial, algunos de sus aspectos metodológicos, históricos y filosóficos. -/- In the second half of the nineteenth century the positive philosophy was consolidated as the dominant current of thought in Mexico, many thinkers used it as the theoretical framework to interpret past events and project the future of the nation. Because of its analysis, explanation and interpretation of the national Mexican history México: su evolución social is the culminating work of Mexican positivism. To our surprise, the work has been little studied by scholars hence it is necessary to recover it. In this article we want to do that task and for that we will focus on analyzing the research method used in the work as well as the role played by history within it. The aim then is to contribute to studies on Mexican positivism by approaching, in a crucial work, some of its methodological, historical and philosophical aspects. (shrink)

I distinguish several doctrines that economic methodologists have found attractive, all of which have a positivist flavour. One of these is the doctrine that preference assignments in economics are just shorthand descriptions of agents' choice behaviour. Although most of these doctrines are problematic, the latter doctrine about preference assignments is a respectable one, I argue. It doesn't entail any of the problematic doctrines, and indeed it is warranted independently of them.

In this paper I study how the theoretical categories of consumption theory were used by Milton Friedman in order to classify empirical data and obtain predictions. Friedman advocated a case by case definition of these categories that traded theoretical coherence for empirical content. I contend that this methodological strategy puts a clear incentive to contest any prediction contrary to our interest: it can always be argued that these predictions rest on a wrong classification of data. My conjecture is that this (...) methodological strategy can contribute to explain why Friedman’s predictions never generated the consensus he expected among his peers. (shrink)

Este documento analiza las siguientes cuestiones: 1) La metodología de la economía y su actual institucionalización. 2) La definición de Economía. 3) Las perspectivas de los economistas acerca de la Economía, sus métodos y justificación. 4) Comprobación y progreso: Popper y Lakatos.5) Los modelos y sus supuestos. 6) Persuasión retórica y verdad. 7) La Economía como un recurso para la Filosofía de la Ciencia. 8) Expansionismo explicativo y relaciones interdisciplinares.

In this paper I study Milton Friedman’s statistical education, paying special attention to the different methodological approaches (Fisher, Neyman and Savage) to which he was exposed. I contend that these statistical procedures involved different views as to the evaluation of statistical predictions. In this light, the thesis defended in Friedman’s 1953 methodological essay appears substantially ungrounded.

The paper analyses economic evaluations by distinguishing evaluative statements from actual value judgments. From this basis, it compares four solutions to the value neutrality problem in economics. After rebutting the strong theses about neutrality (normative economics is illegitimate) and non-neutrality (the social sciences are value-impregnated), the paper settles the case between the weak neutrality thesis (common in welfare economics) and a novel, weak non-neutrality thesis that extends the realm of normative economics more widely than the other weak thesis does.

In this paper I explore a positivist methodological tradition in early demand theory, as exemplified by several common traits that I draw from the works of V. Pareto, H. L. Moore and H. Schultz. Assuming a current approach to explanation in the social sciences, I will discuss the building of their various explanans, showing that the three authors agreed on two distinctive methodological features: the exclusion of any causal commitment to psychology when explaining individual choice and the mandate to test (...) the truth of demand theory on aggregate data by statistical means. However, I also contend, from an epistemological point of view, that the truth of demand theory was conceived of in three different ways by our authors. Inspired by Poincaré, Pareto assumed that many different theories could account for the same data on individual choice, coming close to a kind of conventionalism -though I prefer to refer to this position as theoreticism. Moore was himself akin to Pearson's approach, which could be named descriptivist insofar as it resolved scientific laws into statistical descriptions of the data. Finally, Schultz tried to reconcile both approaches in an adequationist stance with no success, as we shall see. (shrink)

Review of The Philosophical Origins of Austrian Economics, by David Gordon. Auburn, Alabama: Ludwig von Mises Institute, 1993.

The article discusses Friedman's classic claim that economics can be based on irrealistic assumptions. It exploits Samuelson's distinction between two "F-twists" (that is, "it is an advantage for an economic theory to use irrealistic assumptions" vs "the more irrealistic the assumptions, the better the economic theory"), as well as Nagel's distinction between three philosophy-of-science construals of the basic claim. On examination, only one of Nagel's construals seems promising enough. It involves the neo-positivistic distinction between theoretical and non-theoretical ("observable") terms; so (...) Friedman would in some sense argue for the major role of theoretical terms in economics. The paper uses a model-theoretic apparatus to refine the selected construal and check whether it can be made to support the claim. This inquiry leads to essentially negative results for both F-twists, and the final conclusion is that they are left unsupported. (shrink)

A rejoinder to commentators of the paper by P. Mongin, "Le réalisme des hypothèses et la "Partial Interpretation View"", Philosophy of the Social Sciences, 18, 1988, p. 281-325. (This paper is listed and made available by Philpapers.).

Austrian economics starts out from the thesis that the objects of economic science differ from those of the natural sciences because of the centrality of the economic agent. This allows a certain a priori or essentialistic aspect to economic science of a sort which parallels the a priori dimension of psychology defended by Brentano and his student Edmund Husserl. We outline these parallels, and show how the theory of a priori dependence relations outlined in Husserl’s Logical Investigations can throw light (...) on the Austrian account of entrepreneurship.
