The meaning of heterodox economics, and why it matters

Heterodox economics is often defined as potpourri of of schools, too many to mention. Further, most of these heterodox schools are defined against marginalism (or neoclassical economics, which is also a fragmented school of economic thought).  In this sense, the heterodox camp is defined in a negative (against orthodox) and fragmented (depending on what aspect of orthodoxy is contested) way.  I think that is a counter productive approach, and that heterodoxy should be seen as a set of principles.  A positive (in its own terms) and unified (in the sense of the minimum set of propositions that are universally accepted) definition of heterodoxy is necessary.

Two things are central from my point of view.  First, heterodox economists are concerned with the amplified reproduction of society, and this implies that the production and distribution of the social surplus is central for their theories.  This is part of a tradition that harks back to classical political economy.  The determinantion of the surplus implies that distribution is determined exogenously by social and institutional conditions (be that the real wage as affected by the bargaining position of the labor class, or the rate of profit as determined by the monetary rate of interest influenced by the central bank).  Further, the determination of surplus, for an externally determined distribution, and a given technology, provides an explanation of relative prices (value).

It is important to note that there are several particular theoretical ways of approaching each of these questions associated to the reproduction of the economy.  For example, some Marxists emphasize that relative prices are proportional to the amounts of labor directly and indirectly needed to produce the commodities.  Sraffa provides a different approach, that is compatible with Marx's views of the working of the economy.  Post Keynesian groups that emphasize the determination of prices according to full cost pricing are also compatible with this general preocupation about the determination of the social surplus.  In other words, several schools of thought are heterodox in the acceptance of the necessity of understanding how the surplus is generated and distributed, even if they have different theories (that are not always compatible among them).

The second essential proposition that defines heterodoxy is related to the theory of output and employment determination.  Heterodox economists believe that output is demand determined.  That is, autonomous spending determines the level of activity.  There are a few implications to this simple proposition.  First, the level of autonomous spending will only generate full employment of productive resources by chance, and unemployment is a permanent feature of the economic system.  Second, as the level of income equilibrates savings to investment, the rate of interest must be a monetary (not real phenomenon). Additionally, heterodox economists argue that effective demand is valid in the long run.

In sum, if one believes that prices reflect, for a given technology, the way classes struggle for higher income shares within the process of reproducing the material conditions for survival (including processes in which there is accumulation), and one believes that output and the process of accumulation are driven by the exogenous forces of demand, one may be called heterodox.

Some other issues are often seen as central for defining heterodox economics.  Endogenous money is a typical example.  And it is true that most, if not all, heterodox economists follow some version of endogenous money theory.  However, it is clear that even if money is not endogenous, the rate of interest is still a monetary variable in heterodox economics (e.g. in Keynes' General Theory).  Also, several mainstream economists have endogenous money, from Wicksell to those using the Taylor rule now. The same could be said about true or non-probabilistic uncertainty.  It is important, but neither the determination of prices of production or effective demand are directly affected by uncertainty.  And several Austrians (hardly heterodox according to the criteria above) are very fond of the idea of uncertainty.  The last additional issue that sometimes is used to define heterodoxy is complexity (or non-ergodicity), but is the least relevant.  The main difference between heterodox and orthodox are related to causality issues, and they can be reproduced in simple or complex theoretical frameworks.

The obvious question that anyone may pose is why does it matter to define heterodox economics precisely.  For example, Colander, Holt and Rosser (CHR) suggest that heterodox economists should not consider themselves heterodox but just economists, and try to influence the mainstream working with the best among the orthodox.  The problem is that logic and evidence can support either prices of production or supply and demand, and, by the same token, either Say's Law or Effective Demand must be wrong.  In economic policy compromise might be possible, but in theory principles cannot be compromised.  I replied to their paper here.

  1. Matías: ¿sos un joven economista argentino que te fuiste a Utha a hacer una suerte de maestría o doctorado?

    Me interesan los temas sobre los que escribís. Lo único que lamento es que mi inglés no es tan avanzado como el tuyo. Te envidio en eso (en otras cuestiones te tendré que ir criticando, aunque me duela el alma). Pero fuera de joda, me parece que es productivo que te pongas a escribir sobre estos temas y que lo pongas a disposición de todo el mundo.


  2. Un no tan joven (42) economista argentino, que creció en Brasil, y estudió en Nueva York (New School), y fue a parar a Salt Lake (via Kalamazoo, Michigan). Este post salió en castellano acá Gracias por el comentario.

  3. Matias o cara é Dequech com c e não s. Dá uma corrigida no seu paper. O irmão dele, André, é um tremendo pianista e eu tenho dívidas musicais com ele.

  4. No texto publicado foi corrigido. O erro ficou no Working Paper. Mas o JPKE tem gente pra verificar.

  5. I came here following a link from another piece in this blog (MMT and its discontents).

    I agree with all the points made, but I would like to ask something:

    (1) what's your opinion about the whole methodological individualism/microfoundations /rationality/marginalism project?

    (2) is this project compatible with heterodox economics, in your view?

    Muchas gracias y saludos. Muito obrigado e até mais.

  6. Hi Magpie, some authors that consider they are heterodox (even radical) like Sam Bowles do believe that everything should be built on the basis of individual behavior. The classical tradition starts from class behavior, and individuals are subsumed in the social categories. I tend to think that the latter is the way to go. In terms of the marginalist/neoclassical project it is clear that you need individualism, since subjective preferences do play a role in demand. In terms of the project of showing that distribution is determined by supply and demand for factors of production is just a failure.

A few brief comments on Brexit and the postmortem of the European Union

Another end of the world is possible
There will be a lot of postmortems for the European Union (EU) after Brexit. Many will suggest that this was a victory against the neoliberal policies of the European Union. See, for example, the first three paragraphs of Paul Mason's column here. And it is true, large contingents of working class people, that have suffered with 'free-market' economics, voted for leaving the union. The union, rightly or wrongly, has been seen as undemocratic and responsible for the economics woes of Europe.

The problem is that while it is true that the EU leaders have been part of the problem and have pursued the neoliberal policies within the framework of the union, sometimes with treaties like the Fiscal Compact, it is far from clear that Brexit and the possible demise of the union, if the fever spreads to France, Germany and other countries with their populations demanding their own referenda, will lead to the abandonment of neoliberal policies.

A brief note on Venezuela and the turn to the right in Latin America

So besides the coup in Brazil (which was all but confirmed by the last revelations, if you had any doubts), and the electoral victory of Macri in Argentina, the crisis in Venezuela is reaching a critical level, and it would not be surprising if the Maduro administration is recalled, even though right now the referendum is not scheduled yet.

The economy in Venezuela has collapsed (GDP has fallen by about 14% or so in the last two years), inflation has accelerated (to three digit levels; 450% or so according to the IMF), there are shortages of essential goods, recurrent energy blackouts, and all of these aggravated by persistent violence. Contrary to what the press suggests, these events are not new or specific to left of center governments. Similar events occurred in the late 1980s, in the infamous Caracazo, when the fall in oil prices caused an external crisis, inflation, and food shortages, which eventually, after the announcement of a neoliberal economic package that included the i…
