“Popper, Objective Knowledge, p. 266

Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.

“Robbins (1932): An Essay on the Nature and Significance of Economic Science, p. 1

The efforts of economists during the last hundred and fifty years have resulted in the establishment of a body of generalisations whose substantial accuracy and importance are open to question only by the ignorant or the perverse.“

“Kurt W. Rothschild (1999): To Push and to be Pushed, 5

[A] plurality of paradigms in economics and in social sciences in general is not only an obvious fact but also a necessary and desirable phenomenon in a very complex and continually changing subject.“

pluralism and the complexity of social phenomena

• The empirical justification: reality is messy and diverse.

• Social phenomena are multifaceted, diverse and constantly changing, which allows or

even affords taking a variety of perspectives on a given subject.

• Different theories are possible more like maps for diverse tasks (driving a car, navigating

a ship, hiking...), i.e. serving different purposes (Giere 1999)

• Why ‚reality is messy?‘ — different angles on problem + low power of tests to weed out

true theories

• Different Theories are then not necessarily

always antagonistic, but may also be

complementary or neutral to each other.

“Albert 1991, 61, translation JK

…monism of theories [...] can easily have the consequence of using facts only for the illustration or backup of the predominant theory, and interpreting them in a compliant way.”

pluralism, openness and the appraisal of theories

10

Page 29: Kapeller - Pluralist and heterodox economics

Jakob Kapeller

Does science need pluralism?

• Three major reason for pluralism in science and economics:

• (1) Fallibilism: As there is no certainty a perfect theory, which can never be improved or

replaced by a superior alternative, can never be found. Diversity in ideas is crucial for

avoiding dogmatism.

• (2) Social phenomena are complex and multi-faceted, which might require a diversity

of perspectives to adequately understand and address a given problem or phenomenon.

Theories are only „partial theories“ (Rothschild).

• (3) Practical requirements in theory-appraisal: openness vs. prejudice in theory-testing.

Without theoretical alternatives falsification is impossible (as falsification requires the

corroboration of an alternative theory - no falsification without alternative!)

“Paul Davidson’s personal recollection of one reviewer of a failed NSF grant in 1980; cited according to King (2003, 134)

It is true that Davidson has a very good track record and surprisingly good publications, but he marches to a different drummer. If he is marching to a different drummer, if his music is different, then he ought to get his own money and not use ours.“

Jakob Kapeller

Rothschild (2008), Apropos Keynesianer, 25,Translation JK

The confrontation heterodoxy vs. mainstreams emerges from the current state of contemporary economics, which is characterized by a strong preference for neoclassical approaches and assumptions. Such a research orientation is fostered by economic teaching and plays a decisive role for career-prospects in academia. This lopsidedness affects all non-neoclassical and critical approaches, which explains and justifies the emergence of a ‚heterodoxy‘ in economics.“

Page 42: Kapeller - Pluralist and heterodox economics

heterodox economics opposition or coherence?

Page 43: Kapeller - Pluralist and heterodox economics

Jakob Kapeller

Dequech (2007-8), JPKE, p. 301

One can define heterodox economics negatively, in opposition either to the orthodoxy or to the mainstream. The first alternative is based on intellectual criteria (the divergence from at least some of the main orthodox ideas), and the second on sociological ones (lesser prestige and influence). […] Another possibility would be to define heterodox economics positively, as an intellectual category that is not defined exclusively in opposition to orthodox. When applying this positive concept historically, the result may be an empty set.“

Heterodoxy as pure opposition?

Jakob Kapeller

Heterodox Economics Newsletter:What is heterodox economics?http://heterodoxnews.com/HEN/home.html

Heterodox Economics is an umbrella term covering various strands of economic thought as well as a series of interdisciplinary research fields. While heterodox economics is internally highly diversified, most heterodox economists agree on certain conceptual definitions (e.g. doing economics is to study the process of social provisioning in a broad sense), theoretical foundations (e.g. the role of uncertainty in economic action or the importance of the principles of effective demand and endogenous money) and a common epistemological framework, that takes the form of pluralist engagement.

My honest answer to that question was that they don’t think about it. For the most part, the mainstream is unaware of the existence of an ‘outside-the-mainstream’ heterodoxy.”

Heterodox United vs. Mainstream City? Sketching a Framework for Interested Pluralism in Economics

Leonhard Dobusch and Jakob Kapeller

Abstract: Pluralism is a key term in the current discourse in heterodox economics, emphasizing the need for greater theoretical integration and institutional cooperation of different economic traditions. However, both the nature of pluralism and the concrete role ascribed to pluralist thinking for the development of economics have been somewhat contested, pointing to a lack of (widely agreed) conceptual foundations. This paper addresses this conceptual gap by proposing a framework for interested pluralism as a guideline for organizing heterodox economic research, in particular, as well as economic debates, in general. In essence, interested pluralism suggests replacing the traditionally invoked demarcation criteria between different economic traditions by a set of rather ecumenical pluralist principles, whose concrete implications for economic research we discuss. Keywords: heterodox economics, paradigms, pluralism, sociology of economics JEL Classification Codes: A14, B40, B50

[A] plurality of paradigms in economics and in social sciences in general is not only an obvious fact but also a necessary and desirable phenomenon in a very complex and continually changing subject. … Depending on circumstances and the problem to be tackled, different approaches, or a combination of them, have to be used in order to be able to get nearer to the far-away “truth.”

— K.W. Rothschild (1999, 5)

The rise of the neoclassical paradigm to unprecedented dominance in economic thought has been matched by the parallel growth of literature on economic pluralism, mostly put forward by schools of economic thought, which have found themselves increasingly marginalized.

understanding. Here, again, a “Colanderian” approach of searching for a discourse on the level of economic policy (Colander et al. 2010, 406) might prove more fruitful (and also more “pluralist”) than the “classical” approach of invoking fundamental theoretical debates.

Practicing Pluralism: Integration, Diversification, Comparison, and Exchange

While “disinterested pluralism,” or “plurality,” implies fragmented, divergent

approaches, we can associate “interested pluralism” with the integration of different schools of thought (Bigo and Neru 2008). But what does a quest for integration entail for research practice, in general, and individual researchers, in particular? Since we have developed our concept of a “pluralist paradigm” from an empirically descriptive perspective, this question has implications beyond the normative. The viability of any framework for interested pluralism also depends on its ability to inform the practical conduct of individuals and groups researching within the economic discipline, thereby taking into account existing institutional restrictions for more (interested) pluralism. We first discuss implications on a general level and then turn to concrete examples from the heterodox economics discourse, where differences and similarities between various traditions are relatively well documented. However, in theory, the same arguments also apply to other dissenting traditions or economists.

In light of Frederic Lee’s (2010, 19) stance that pluralism implies “engagement across different heterodox approaches,” we argue that this engagement would be most productively realized at the level of theoretical statements, dealing with distinct empirical phenomena. Instead of comparing paradigms at an abstract level, this approach allows for the comparison of theories, as well as the continuation of empirical work, on real-world economic problems. Essentially, we advocate the systematic comparison of theoretical statements from different heterodox traditions, resulting in different research practices (see Table 4). This would allow pluralist practices to be interpreted as complementary research strategies, whose orientation depends on the relationships between different theoretical statements stemming from distinct schools of economic thought.

Debt, boom, bust: a theory of Minsky–Veblen cycles

Abstract: This article reflects on the economic development leading to the recent crisis and interprets this development as a series of events within a Minsky–Veblen cycle. To illustrate this claim we introduce conspicuous con-sumption concerns, as described by Veblen, into a stock-flow-consistent post Keynesian model and demonstrate that, under these conditions, a decrease in income equality leads to a corresponding increase in debt-financed consump-tion demand. Here Minskian dynamics come into play: if perceived economic stability causes banks’ margins of safety to decrease sufficiently, increased credit demand is accommodated by credit supply giving rise to a debt-financed consumption boom. As the solvency of households decreases and interest rates move up, banks reduce lending, triggering household bankruptcies and, finally, a recession. What follows is a stable period of consolidation, where past debts are repaid, financial stability is regained and conspicuous consumption motives may gradually take over again. We illustrate this approach to the current crisis and its explanatory validity by extending our stock-flow-consistent model into a dynamic simulation.

Key words: financial instability, inequality, business cycle, stock-flow consistency, Minsky, Veblen.

JEL classifications: B52, D11, E12, E20, G01.

If one were asked by an educated layperson about the best way to under-stand the “current crisis,” which has already evolved from a financial or private debt crisis to a sovereign debt crisis, we claim that one legitimate answer would be the following: first, read Thorstein Veblen’s seminal book The Theory of the Leisure Class (especially chapters 4–5), and pay

The basic story

The research questions

1.) Can the recent crisis be interpreted as a part of a larger cycle?2.) Is it possible to create such cycles in a post-Keynesian, stock-flow consistent framework?3.) If yes, what assumptions are sufficient to acquire such a result?

Out

put

Debt

Expansion Compression

Panic

Consolidation

Framework and main assumptions

stock-flow-consistent closed economy model with no state

a Minskyian financial sector, where banks become more confident in stable periods and get more anxious in volatile periods

two classes (workers and capitalists)

two types of workers, where type 2 workers lose income relative to type 1 workers, which gives rise to conspicuous consumption motives that increase the demand for consumer credit and boost aggregate demand

The answer

Expansion

Compression

Panic

Consolidation

A simulation model based on these specs delivers the following cyclical behavior of aggregate output...

...which is accompanied by the expected debt-output cycle (the amount of dots indicates the duration of the respective phase).

other workers/their old living standard -

Credit-Demand!

The basic story

The research questions

1.) Can the recent crisis be interpreted as a part of a larger cycle?2.) Is it possible to create such cycles in a post-Keynesian, stock-flow consistent framework?3.) If yes, what assumptions are sufficient to acquire such a result?

Out

Debt

Expansion Compression

Panic

Consolidation

Framework and main assumptions

stock-flow-consistent closed economy model with no state

a Minskyian financial sector, where banks become more confident in stable periods and get more anxious in volatile periods

two classes (workers and capitalists)

two types of workers, where type 2 workers lose income relative to type 1 workers, which gives rise to conspicuous consumption motives that increase the demand for consumer credit and boost aggregate demand

The answer

Expansion

Compression

Panic

Consolidation

A simulation model based on these specs delivers the following cyclical behavior of aggregate output...

...which is accompanied by the expected debt-output cycle (the amount of dots indicates the duration of the respective phase).

The basic story

The research questions

1.) Can the recent crisis be interpreted as a part of a larger cycle?2.) Is it possible to create such cycles in a post-Keynesian, stock-flow consistent framework?3.) If yes, what assumptions are sufficient to acquire such a result?

Out

put

Debt

Expansion Compression

Panic

Consolidation

Framework and main assumptions

stock-flow-consistent closed economy model with no state

a Minskyian financial sector, where banks become more confident in stable periods and get more anxious in volatile periods

two classes (workers and capitalists)

two types of workers, where type 2 workers lose income relative to type 1 workers, which gives rise to conspicuous consumption motives that increase the demand for consumer credit and boost aggregate demand

The answer

Expansion

Compression

Panic

Consolidation

Conclusion

• Pluralist approach leads to new contributions/perspectives

• Integration of different traditions: New Perspectives!

• pluralism ≠ anything goes.

• Obvious example in complexity econ: Keynes-Schumpeter models (e.g. Dosi et al.)

• Pluralist economics in practice: the new heterodoxy?

• Post-Keynesianism + Old Institutionalism ➝ Minsky-Veblen Cycles

• + complexity economics ➝ Polarization in Europe

• (+ economic sociology ➝ Performativity! Role of models in policy-making!)

• (+ heterodox trade theory ➝ path-dependency in supply-side structures!)

• … [many more things]
