Some Methodological Aspects of the Institutional-Mainstream Debate

As for the conclusions to be elaborated it is necessary to call attention to an important distinction. Even though both institutional economics and the main stream apply ideal-types, these concepts have different ontological status in each system. Perfect competition and oligopolistic competition, or price taker firms and price setting companies: they are all ideal-types. In spite of the fact that all of these concepts refer to something (as Putnam [1975] would put it, there are some real entities that approximately fit the descriptions given by these concepts[1]), they are used for miscellaneous purposes. In Mäki Uskali’s [1994] phrasing, some concepts are more de-idealized than others are. By constructing far more de-idealized concepts and mechanisms, institutionalists intend to give descriptions of agents and processes actually perceived in our socio-economic reality. Institutionalists following such an epistemological strategy can endow their concepts with considerable direct descriptive relevance. In other words, through institutional concepts reality can be described with a good approximation as we fellow men directly experience that. If highly abstract mainstream concepts and models are judged by the same standards, neoclassical orthodoxy avowedly incapable of providing direct descriptions will always prove to be a failure.

This distinction can be explained by referring to different schools of the economic thought following radically different conceptualizing principles. Every research tradition exhibits specific metaphysical and methodological commitments and is built upon a special ontology that is expected to serve as a catalogue of the entities the given research tradition concedes as existent (cf. Laudan [1977]: 78–79). While the central problem of the methodology of mainstream economics has been the following of the Menger–Weber methodology,[2] institutional economics has been under the influence of thinkers (such as Keynes or Marx) who are not even referred to as economists in the main stream sense of the word. No matter how compatible these methodologies actually are, careful accounts are hindered by the lack of tolerance.

It is not an overstatement to say that the institutional critique against mainstream economics is the result of institutional economists’ setting their own methodological requirements on the mainstream camp. This development seems to stem from a Kuhnian way of thinking. In order to enhance scientific progress the reigning paradigm with lots of anomalies accumulated needs to be subverted. But here is the rub: economics developing along a particular epistemic strategy is completely different from physics described by Kuhn [1970]. While in physics the significant theoretical systems have been built upon one another in a non-cumulative way with the consecutive paradigms being more and more comprehensive approximations to reality (Weinberg [2015]: Ch. 15), economics is selective, highlighting some facets of our socio-economic reality—facets which we as researchers are currently interested in (cf. Contessa [2007]). This is nothing but theoretical pluralism in which every participant argues for the supremacy of his own absolutized approach. It would be difficult to give a different account of how direct empirical evidence became the principle of conceptualization and building models in institutionalism. At the same time, the very indirect, abstraction-based relationship between mainstream models and reality is found inappropriate or of dubious value at least. The same suspicion is felt about the fact that falsification of mainstream theorems must be carried out via complex econometric methods, where numerical results of questionable value confirm the circumstance if a model under test succeeded in highlighting some of the mechanisms of reality.[3] The desire of totality will always feel tempted to question the relevance of fragmentariness. Hereby I argue that fragmentariness of the main stream is on purpose, so it does need institutional and other amendments. It stands to reason that mainstream ideal-types are not capable of direct description. However, it must be noted that along a different epistemic strategy such concepts may prove to be useful or even indispensable. Critiques highlighting the break between mainstream economics and reality can be refuted in two interrelated steps. First, abstract ideal-types are introduced as instruments used for grabbing (socio-economic) laws. And second, some light is casted on the theoretical importance of comparative studies between model and reality. Following this line of reasoning some mainstream efforts of dubious value in grabbing certain fundamental laws are also mentioned.

One can hardly win a debate between approaches equal in epistemic value and different only in purposes. The dissatisfaction with mainstream economics does not stem from anomalies but it is simple dissatisfaction of some authors with the scope of mainstream models. The hard core remains intact all along: instead of subversion, the dissatisfied following their own interests have proceeded by elaborating further models and theories. These new theories stand in a complementing relationship with the hard core, since they are aimed at answering questions which the mainstream camp is not interested in. In this context identifying the area covered by mainstream economics is of crucial importance which is definitely an act of methodological nature. Since any theory is built upon implicit and explicit methodologies and ontologies, understanding the positive theoretical content can only be carried out by taking this methodology and ontology into account. Strange as it is, while Kornai [1971] promised his critique would be of methodological character as well, the debate between mainstream economics and the rivalling approaches has never taken a methodological path—as a result, methodology still has rather an unfavourable status among economic sub-disciplines (cf. Weintraub [1989]). However, without clarifying the methodological foundations one can hardly reach beyond rehearsing dogmatically some unproductive critiques of the main stream, questioning relevance, mixing up the complex relationship between models and reality with a simple contradiction—and beyond some kind of obtuseness over why a critique ignoring methodological aspects remains neglected.[4]

The traditional way of using ideal-types is comparison underlined by Menger–Weber. On the contrary, using ideal-types for direct description is something different, even though such efforts were present even in his Weber’s time due to the Marxian way of theorizing.[5] Thus, there is a neoclassical methodology of applying ideal-types. Its technical details and epistemological principles are very different from the institutional purposes of direct description, so judging the relevance of mainstream economics is reliant on analysing methodology. Only one question has stood in the centre of the debates around mainstream economics for decades: if models are not suitable for the purpose of direct description, then what are they suitable for at all? This paper is aimed at calling attention to a relationship that still seems to be strong between the neoclassical founding masters and modern business-cycle theorists. Achieving this purpose provides an answer to this question.

Notes

[1] As for the interpretation of mainstream economics, it is of crucial importance to analyse how some concepts such as the homo oeconomicus can refer to real entities while no economic men possessing the neoclassical characteristics are in existence actually.

[2] Several items in the history of economics underline the fact that both neoclassical economics and mainstream economics rooted in that are considerably heterogeneous and today’s main stream has reached far from the original neoclassical fundaments. At the same time, the norm of the relationship to reality has not changed. It is exactly the thing that can serve as a single line for the 150-year-long history of mainstream economics.

[3] In this regard, the debate between Lucas and Rees is particularly interesting. At a point, the debate turned out to be unfruitful, which was an additional item to the factors urging the main stream to withdraw into their ivory tower. Lucas and Rapping’s hypothesis according to which a voluntary component was an effective constituent in the unemployment under the Great Depression was carelessly confused with the utterance never stated that unemployment is voluntary.

[4] Weeks [1989] is perhaps the best example for how demanding a rivalling theoretical approach stops one even from considering the relevance of the neoclassical main stream. John Weeks passes a sentence upon neoclassical economics not even mentioning the big questions of neoclassical epistemology and completely neglecting the results of 19–20th century philosophy of science (especially the Vienna Circle). It is much more troublesome that he overlooks all the methodological aspects and consequences of the neoclassical, monetarist and new classical texts, even if Lucas dug into meta-theoretical reflections as for the problem of relevance deeper than anyone else did before. Colander [2009]: 8 gives judgement against the main stream along the same strategy. Everybody is free to decide whether neglecting an aspect, which is of primary importance as for the critique, undermines the critique itself.

[5] Without any attempt to provide even a superficial methodological critique of institutional economics, it is worthwhile to suggest that Weber [1949]: 93–94 found it troublesome to squeeze infinitely complex reality into ideal-types, which cannot be regarded as comparison but direct description.
