An autumn-burnt day


A short holiday…

I am spending my short holiday these weeks. After publishing my new classical book in 2015 I had a very tough 2.5-year-long period with working under a lot of pressure. I needed to have a rest just to reorganize myself in order to return to work as relaxed and refreshed as possible. From 19 to 29 October I spent some days in Sopron, a beautiful small town in the North-west of Hungary, near the Austrian border. I tried my best to devote as much time as possible to mental and physical recreation. The result was plenty of coffee, cakes and long walks in the streets or in the mountains rising in the distance. Here are some pictures…

Editorial: The methodology of contemporary macroeconomics

The Editorial Board of Economics and Business Review intended to devote this special issue to the emerging field of the philosophy of economics. This subdiscipline of our profession is rather in its youth, however, showing the signs of maturity. Philosophy or methodology of economics has several international organizations, leading journals and even book series—all of which serve only one purpose: to interlink those researchers who make considerable efforts to approach our traditional problems from a different point of view. As Polish researchers are particularly active in this field, the pleasure was mine when the EBR asked me to join this interesting project as a guest editor. I am really indebted to the Editorial Board for initiating me in the tough process of setting up this issue from the first occurrence of the idea. Thanks to our joint efforts, we could team up prominent and illustrious authors to share their thoughts regarding the sophisticated question of the methodology of contemporary macroeconomics. It is an additional source of pleasure for me that we really have an international cooperation of authors from the United Kingdom through the Netherlands and Poland to Hungary, where even the ages of our contributors show a great variety. It was an explicit editorial policy of ours to encourage the dialogue between researchers of different ages and countries. By having rejoinders to all our papers, we have both interesting pairs of senior and early-stage researchers and the hope of creating the possibility of new and burgeoning research links.

Why macro, you may ask. We are living in an age where the former myth of stable macroeconomies is dead once and for all. After severe world economic turbulences, macroeconomics faced serious challenges. Even though it is exactly such recurrent episodes of falls and rises in general macroeconomic performance that gave birth macroeconomics some decades ago, since 2008 there have been several voices claiming that modern macroeconomics, be it business-cycle theory or growth theory, has lost its relevance as to practical economic policy. Understanding business cycles has been a central topic in modern macroeconomics for decades. Business cycles are complex phenomena, so the underlying causal structure is difficult to disentangle. Different schools of the economic thought have attributed different causes to the same event. Neoclassical orthodoxy tries to address the problem in a choice-theoretic framework, while heterodox currents challenge this approach by emphasizing a multitude of possible social, institutional or even political causes. Due to these efforts, by now we not only have known a great deal about the nature of business cycles but also about the possible ways of treatment. The high importance of these theories is indicated by the number of Nobel prizes awarded for the related achievements.

However, it is easy to realise that the difference between the approaches stems from the difference between the methodologies along which the traditions try to address their chosen problems. Locking away in their own methodologies has triggered a demarcation between the different schools. This process of sharpening demarcation has led to an unfavourable situation in which different schools cannot even communicate with one another, despite all of them contribute to the highly complex endeavour of understanding capitalist economies. This is the reason why I think that the understanding of methodologies must be the first step to the understanding and the reconciliation of the different thoughts in economics. By this special issue we tried to create a new platform for sharing ideas in order that at least our contributors could start new dialogues.

As guest editor I have the privilege of giving a short introduction of the six papers and rejoinders included in this special issue. There occurred some topics around which the contributions of our authors can be easily grouped. Such a topic was János Kornai’s oeuvre. Janos Kornai is still the most influential economist in Central Europe who devoted several magnum opuses to the understanding of the command economy. Thanks to him, we know a great deal about this episode of economic history today. However, his works are not only memories of the past. It is sad but true that Central European economies inherited several problems of the preceding socialist era. Our current macro-social problems can easily be traced back to the crisis phenomena of socialism. Corruption, the over-emphasized role of the state, poverty, wage tensions or inadequate education: all these challenges are rooted in the past and for the ultimate sources of our present-day problems stem from the past, we also need to look back on the past when it comes to formulizing our solutions. But for Kornai’s intellectual efforts, I am sure we would be hopeless at even realizing the problems, let alone seeking the answers. As Janos Kornai was awarded a Doctor Honoris Causa from Poznań University of Economics already in 1978, it was an explicit editorial policy to place emphasis on the assessment of his intellectual heritage and to render a tribute on occasion of his 90th birthday.

Accordingly, László Csaba reviewed Kornai’s oeuvre from a unique point of view. For Kornai’s critique of the neoclassical orthodoxy is still relevant, László Csaba gave a detailed analysis of the relationship between formalized mainstream economics and Kornai’s comparative economics. This is the line along which Kornai’s lifework unfolds. In contrast, Prof. Peter Mihályi focused on one item of Kornai’s lifework. In 1972 Kornai published his most debated book under the title Anti-equilibrium which was supposed to be a grandiose mainstream-critique. Even though as a critique this work of Kornai could only moderately succeed overseas, in Europe and especially in Central Europe Anti-equilibrium triggered a completely new line of thinking. As a result a new standard emerged to address the relationship of macro-models to reality. A more direct relationship has become established recently which has led to the need of a dedicated European Economics. However, oftentimes Anti-equilibrium is still regarded as Kornai’s most influential book, having opened the avenue for new research initiatives. In this vein Peter Mihályi devoted his paper to a simple micro-level observation provoked by the Anti-equilibrium according to which there are some common symptoms both in command and competitive economies. Peter Mihályi’s paper proved to be a genuine example as to how to interconnect micro- and macro-levels outside the mainstream camp.

Following the problems of the micro-foundations project of modern macroeconomics, Michael Joffe turned his attention to a micro-founded theory of economic growth. As is well-known, the microfoundations make up one of the most problematic areas of modern macroeconomics. Not even the mathematical tractability of the project is often-questioned, but also the very idea of placing macroeconomics on a microeconomic footing is widely debated.  Michael Joffe takes a sceptical attitude towards mainstream growth theories for these models in his view fail to give account of even the main features of economic growth. His answer is to suggest a more comprehensive approach to include more factors than the commonly known growth theories. Michael Joffe’s paper proved to be a thought-provoking initiation in addressing a well-known problem from an ignored point of view.

It is time to say something positive about neoclassical orthodoxy and modern macroeconomics as such. It is Pawel Kawalec who undertakes this task which seems considerably difficult to complete in a day and age when counter-mainstream currents are growing in both strength and intensity. Very recently Paul Romer made an effective attack against DSGE-models on methodological grounds. Pawel Kawalec made efforts to dig deep in order to take up the quarrel of DSGE-models at the root of the problem. By so doing Kawalec turns to the history of economics, so his paper is part of a growing number of treatises that take the history of economics and economic methodology as two interconnected and closely related subdisciplines. Judged by scientific representation standards DSGE-models seem to meet the common epistemic standards of scientific research.

Jerzy Osiatyński, a former student of legendary Polish economist Michał Kalecki, outlines ways as to how Kalecki contributed to the evolution of Keynesianism in the decades after the publication of Keynes’ General theory. As Keynesianism, especially the Keynesian approach to large-scale macroeconomic fluctuations, has become an idea different from the mainstream business-cycle approach, these insights invite the reader to consider theoretical economics as a complex discipline. One could hardly find a better account of how different approaches complement each other in economics.

At the end of this editorial note, it is time for me to call upon our contributors to speak for themselves. I hope, this special issue will turn out to be a trigger for new lines of discussion and for a partnership of our authors.

Lars Syll’s ‘elegant’ fantasies

Yesterday I came across one of the lates blog posts of well-known mainstream critic Lars Syll. Prof. Syll is a very interesting figure of modern economic thinking, even if I cannot appreciate his rather passive and destructive critique. I think I can understand his most fundamental claim: neoclassical orthodoxy is irrelevant to real-world economic problems, thus we should drop the whole consruct as completely useless. The reason why I find his critique troublesome and destructive is that he discredits something without suggesting a more approriate framework. It is okay that neoclassical economics was aimed at imitating Newtonian physics. It is okay that Newtonian physics – similarly to neoclassical economics – as a direct description of reality is erroneous. But to say that neoclassical economics and Newtonian physics are failures is something different. Admittedly, the connection between these theories and reality is complex and subtle and one needs to perform a careful analysis in order to assess this relationship. This is the analysis Prof. Syll refuses to carry out. Instead, he draws his conclusions without building a solid footing. Why is economics a failure in understanding reality? Prof. Syll fails to underpin even his own ideas. Philosophy of science and philosophy of physics have been analysing this relationship for centuries. Modern methodology of economics in the realist tradition is in a favourable position for philosophers have a plethora of arguments for the relevance of abstract mathematical sciences such as physics or economics. Any counterarguments that miss considering these powerful philosophical foundations are troublesome . Prof. Syll’s arguments have only one basis: his insistance on the claim that mainstream economics describes nothing. This is almost nothing.

Now let me turn my attention to his current topic, the DSM-theorem.

DSM-theorem (referred to as SMD-theory sometimes) can be regarded as really disturbing, but it rather concentrates on the contradicting relationship between micro- and macroeconomics and not on the (micro-level) postulates of neoclassical. However, it would be a huge mistake to play down the significance of the DSM-theorem (named after the elaborators, Gérard Debreu, Rolf Ricardo Mantel, and Hugo Freund Sonnenschein), since, eventually, it questions the justification of the microfoundations of macroeconomics. The fundamental problem was posed by the relationship between individual and aggregate excess demand functions. As aggregate-level excess demand functions are important for macroeconomics, huge efforts were made to ground these functions at a micro-level. The seminal papers on this topic (Sonnenschein 1972, 1973; Mantel 1973; Debreu 1974) called attention to the fact that however precise we are in specifying the micro-level characteristics, the excess demand function for an economy is not restricted at all by these features. A consequence of the mathematical demonstration of the DSM-theorem was that the general equilibrium of a multi-market macro-system is not necessarily unique (the lack of uniqueness), i.e., we can find multiple price vectors that guarantee equilibrium and the emerging equilibrium states may be unstable in dynamic terms (Giraud 2009). It seems as if DSM-theorem could have dealt mainstream economic theory a final and destroying blow. The relation of mainstream economics to DSM-theorem is portrayed well by the Handbook of Monetary Economics (B. Friedman and Hahn 1990), in which the achievements underlying the theorem were not mentioned even in the References. Mainstream economics disregarded DSM-theorem the same as the inconsistency from the quantity theory and Walras’ law. Frank Hahn (1975) was one of the few who regarded DSM-theorem as the most dangerous critique of mainstream economics. It is understandable somehow, if we consider that the object of the critique, viz. mainstream economics, is an economic theory—while DSM-theorem (however impressive it is) is a mathematical demonstration. Even if we admit that the mathematical grounds of mainstream economic theory are wrong in some respects, the theory was still successful in resolving a lot of economic problems—while DSM-theorem could hardly support us in such a context. The prevailing paradigm is not required to be perfect at all but only to give solutions to several scientific problems. After all, mainstream theory performed well in these terms, and it is also sure that DSM-theorem is never going to help us (say) establish the theoretical grounds for the best operative monetary policy or finding the ultimate causes of cyclical fluctuations to found countercyclical economic policies.

On a methodologically underpinned history of business-cycle theories

Understanding business cycles has been a central topic in modern macroeconomics for decades. Business cycles are complex phenomena, so it is difficult to disentangle the underlying causal structure. The phenomenon itself is the only clear thing: capitalist economies suffer from recurrent episodes of falls and rises in general macroeconomic performance. Different schools of the economic thought have attributed different causes to the same event. Neoclassical orthodoxy tries to address the problem in a choice-theoretic framework, whilst heterodox currents challenge this approach by emphasizing a multitude of possible social, institutional or even political causes. Due to these efforts, by now we have had several explanations each of which highlights some selected facets of the business cycles. As a result, our understanding of the business cycles is made up of partial truths, and such partial truths oftentimes seem to contradict one another. However, a synthesis is possible, thus partial truths as building blocks can form a coherent big picture. Such a synthesis requires us to understand how selective models connect to reality, that is, how models represent the selected parts of our socio-economic reality. Understanding the way models connect to reality requires a methodological analysis, thus the understanding of the different methodologies must be the first step to the understanding and the reconciliation of the different thoughts in economics.

Today multiple disciplines regard modern business-cycle theories as their centres of interest. First, history of economics reconstructs the theoretical content and evaluates the economic policy consequences. However, the analysis of the methodological background is only of marginal importance here. Studies regarding methodological analysis as a crucial constituent has appeared only very recently. These efforts ought to be regarded as pathbreaking initiations; for the most important item, see (De Vroey, 2016). Blaug (1992) is also one of the exceptions. Second, modern philosophy of economics has put the study of modern business-cycle theories under the general interest in economic methodology. The discourse here addresses the methodology of economics as such rather than the methodologies of individual currents. One of the few exceptions (Mäki, 2009) analysed the methodological recommendations of Friedman’s business-cycle theory. This is the book that opened the avenue for a methodological analysis of modern business-cycle theory. However, it is still a question whether its ideas can be extended to the post-Friedmanian achievements.

Today these two approaches (the history of economics and the methodology of economics) constitute two distinct directions. Considering methodological aspects in the history of economics is further hindered by the fact that initially the historiography of economics treated methodology as troublesome and void (Weintraub, 1989). One of the most worrying consequences of this situation is that new insights occurring in methodology cannot or can only slowly and superficially build into the historiographical narratives. A methodologically underpinned history of modern business-cycle theories can fill this lacuna.

The positive content of a theory is inseparable from its methodological background. What we conceive of the possibility of accumulating knowledge of the surrounding reality; of the roles our assumptions play; or of the relationship between our theory and the rival approaches: these considerations require solid methodological footing that may change how we interpret the very theoretical content. How we know something determines what we can know and whether we know something at all (Epstein, 2015). It is particularly true of modern business-cycle theories. When new classical macroeconomics (Lucas, 1972) assumed voluntary unemployment, it seemed as if Lucas and his followers had cancelled the study of involuntary unemployment from the agenda. By contrast, their purpose was to scrutinize whether the workers’ decision to reject job offers contributes to unemployment dynamics. In other words, whether there is a voluntary component in unemployment. Simply put, their focus was on only one component of unemployment dynamics. Unless we clearly recognize this selective strategy, it would seem as if modern business-cycle theory by assuming voluntary unemployment placed the blame on the workforce for remaining unemployed. However, modern business-cycle theory succeeded in revealing how the real structure of the economy without any inference from the institutional environment can lead to large-scale macroeconomic fluctuations. Methodology is crucial for us even to evaluate the economic policy consequences. If only particular mechanisms are selected from the complex causal structure, these particular approaches, if taken at face value, necessarily contradict one another. A thorough methodological analysis will lead to a consensus in which all the rival approaches can find their adequate scopes.

The way business-cycle models connect to reality is unclear. The fundamental question regards whether these models can give approximately true descriptions of the causal structure—or they are useful instruments only capable of generating predictions with considerable empirical performance. This is the conflict that underlies the debate between economic realism and instrumentalism. Realists make efforts to argue for the truth of models, while for instrumentalists, models are only constructs for predictive purposes. However, an instrumentalist model fails to teach us anything about the underlying causes: this leads to no knowledge in the strict sense. Although Mäki (2009) provided strong arguments for the realism of economics, according to the standard interpretation Friedman put economics on an instrumentalist track. Both Lucas and the succeeding RBC-theory are conceived as further steps along this line, so today modern business-cycle theory is regarded as useless in terms of creating true knowledge of the economy. This is a rather worrying interpretation that can deprive economics of the possibility of understanding the causes of business cycles. This interpretation may delimit even the scope of economic policy applications (Elson, 2017).

Admittedly, the full-blown realism of economics seems untenable for some apparent instrumentalist tendencies in modern times. However, Kevin Hoover (2009) made efforts to argue for Friedman’s realism along a more modest line of reasoning. For Hoover, Friedman set up instrumentalist agent-level assumptions to achieve causal realism at a macro-level. However, our knowledge of a causal realism built on agent-level instrumentalism in economics is rather limited.

The main purpose is to consider the plausibility of this mix and to suggest a framework for a methodological history of modern business-cycle theory. This framework is Epistemic Structural Realism (ESR) suggested by John Worrall (1989). In the general philosophy of science Anjan Chakravartty (2007) and Stathis Psillos (2006) clarified structuralist ideas. ESR describes the relations connecting entities (in economics: agents) so that the structure is described at the level of the structure, whilst ignoring the entity-level properties. As causal mechanisms work along the relations that connect entities, ESR is the general philosophical framework in which it can be analysed whether structural/causal realism underpinned by entity-level instrumentalism is a viable option both as an interpretation for the history of economics and as a research strategy for economics.

According to my hypothesis, the answer is negative. Knowledge of the way economic agents connect with their fellows requires knowledge of the properties of the agents. Individuals and their features are prior to the structure, so the structure is derived from the individuals. In economics, the microfoundations carry the macro-level. Providing a realistic description of a structure is impossible through assumptions that abandons the idea of realistic descriptions of individuals. Thus, the proposed project clarifies the relationship between the microfoundations and the macro-level, thus the microfoundations will turn out to be our instruments of connecting with reality. Based on the critically reconsidered ESR, we can judge which chapters of the theoretical evolution are properly anchored to socio-economic reality.

To sum up, the purpose is to analyse how modern theories of the business-cycle have changed in terms of their relation to reality. Through this methodological analysis, I can offer a narrative of the changes in the relevance of theories to understanding socio-economic reality. This narrative can be the first step to a deeper understanding of the relationship of the rival theoretical approaches of the business cycle.

INEM 2017 Conference, Day 3

INEM 2017 conference has just ended on a rainy afternoon. I am full of memories and happy to have some new friends. It was another long day actually, so I need to focus on my overall feelings and insights instead of providing a detailed summary of the day. However, there were some very impressive presentations. Just to mention one, Max Düsterhöft and Thomas Schädlich analyse central bank communication in a language philosophical framework. They have some tricky aspects: clarity, for instance, measured in terems of the length of the sentences or grammatical simplicity. The authors digged down even to Wittgenstein’s language philosophy. It was really a thought-provoking presentation and I was so happy to see how thorough these guys are. Or to mention another talk, Caterina Marchionni in her talk outlined a program along which the achievements in economics can be made horizontal instead of following the common vertical pattern. New models in economics and oftentimes in science as such do not overwrite each other making the former constructs inadequate, but address new questions the preceding models did not pose at all. In my context these thoughts are really relevant for they are in support of my ideas about the complementarity of ‘rival’ theories. In Hungary there are intense debates around the relationship between mainstream economics and institutionalism, regarding the former as irrelevant because of its highly abstract nature. In my view the relationship is of complementing nature (each theory explains something), and this is the reason why I was so happy to listen to Caterina’s presentation.

Today I could gather a lot of general insights why methodology of economics is so important. John Davis in his talk devoted to agent-based modelling called attention to a thought of Brian Epstein according to which how we know something determines what we can know and whether we know anything at all. At the bottom line every discipline is methodology. This is a clear message.

During lunch I found myself in the delightful position of having a chat whit Brian Epstein. I know some works of his, moreover, some panelists directly referred to his thoughts during the conference. He is a real gentleman. At lunch suddenly turned to me and triggered a conversation about his ideas and my ideas and took the trouble to clarify his suggestions about modern business cycle theories. His point is very provocative. For him, the problem is not whether some elements of real-world social systems can be ommitted or not. It is widely believed in the physicalist reconstruction of economics that we have some fundamental laws and there are factors, mechanisms and the like in addition that disturb the working of these laws. For clarity, we oftentimes leave these factors out of the picture in order to focus on the consequences of the fundamental laws. Brain takes a sceptical stance. In his opinion, the microfoundations project is erroneous for such factors are also ommitted that make essential or constituent part of the phenomenon under scrutiny. So in the microfoundations project not only some factors of marginal importance are left out but some essential features of the social universe. This is the reason why the knowledge provided by the microfounded cycle models seem to be so distorted and indadequate.

It is a shocking experience. I think this critique is very effective – it is as destructive as the DSM-theorem. Bearing in mind the social logic of mainstream economics, these thoughts will be ignored for mainstream authors cannot block them.

But the talk with Brian convinced me of a very serious thing. Economists are really naive as far as methodology is considered. Brian could set up an effective critique because he is a philosopher. So, all in all, economics is in need of far more methodological considerations to make its fundaments more consistent. All of us, fellow economists, need to become methodologists first and foremost since it is the methodological circles, debates and the resulting considerations that can really strengthen our science… It is my strong belief.

It is time to say goodby to San Sebastian. I had wonderful four days. I hope we can continue discussing…


INEM 2017 Conference, Day 2

I had a superb view of the ocean from my window at the conference. Is it really a wonder that from time to time I got disorganized and was not able to pay attention to the presentations…? It is a shame, I know…


It was day 2. It was the longest day of the conference with panel presentations from as early as 9:30 up to 19:30. I was listening to so much talks that I need to select somehow or rather focus on my overall feelings and insights instead of a detailed and thematic descriptions of the sessions.

The first block of the day was devoted to experimental economics. There were some interesting points. For instance, Sreeja Jaiswal from India gave a talk about a practical application in which fileld experimental methods were used to evaluate the environmental impacts of some large-scale railroad investment activities. But it was Don Ross who took the morning and made my day. It was an old desire of mine to meet him in person and to attend one of his lectures. Today he presented some brand new (meaning really new) results regarding bundle sequences of choices. This issue may seem complicated at first sight, but at the bottomline you can easily take it in. People have a tendency not to regard some choices invididually and in separated form but they treat them in bundles. Don took an illustrative example: if my problem on a rainy Monday morning regards to have a jog or not to have, I will address the issue in a different way. I will ask myself: am I a serious runner? – and if so, I will go out for a run. It is my attitude towards running that is tested and not my temporary mood. Don and his collaborators created a very effective framework for testing this hypothesis. We the audience were proud to attend the presentation of these results.

After listenig to the majority of today’s preesentations I got under the impression that contemporary philosophy of economics despite its young age reached a post-modern phase. What am I talking about…? Researchers are working on well-defined topics and problems, but these projects are so closed that this closeness somehow hinders the possibility of mutual understanding. A research topic turns some researchers on but the remaing part may be completely ignorant of even the basic terms and problems. This is not an objection rather a concern. Even Jonathan Perraton’s lecture on Piketty’s book calls attention to this surmise. Jonathan underlied that Piketty made some troublesome or arbitrary methodological decisions, but his book is a hit notwithstanding. How is it possible? We live in a day and age when science shows the symptoms of industrial production. This process has its own explanation… Processing or even finding the relevant literature becomes more and more difficult and demanding, so it is no wonder that researchers are prone to work in intellectual isolation. This is the reason why research communities such Rotterdam’s EIPE or Helsinki’s TINT are so precious.

Actually, I am disapponted somehow by the fact that the dissemination of new ideas is rather slow. It is weird that in 2017 mainstream economics is still blamed for its selectivity. It is a fact of life I think. All sciences need to make selections, but I cannot understand why we should squeeze everything into economics. Economics is not political science. Economics is not ethics. Economics is not sociology – so I am wondering at the idea of making economics as a totalist discipline. We have several complementing disciplines. We should let them do their job.

So it was day 2. The grand lunch is on the way, the company are meeting at 20:30 at Palacio Miramar to have the lunch together, to go on discussing and to say goodby to the conference. Tomorrow is the final day.
