Psychologists and the Surplus Approach

I noted before about the fact that historians, like McNeill use the notion of the surplus to explain how primitive societies developed economically. Their lack of modern training in economics is a blessing and they end up using at least some elements of the old classical political economy authors. This is true of physiologist and popular writer Jared Diamond (see here and here). The figure below is from the book Sex at Dawn by two psychologists,  Christopher Ryan and Cacilda Jethá.

While the book is mostly about how behavior, in particular sexual behavior but violence and war too, changed with the development of agriculture, they also introduce the role of the surplus in economic development. Note that the food surplus is what allows for social hierarchy and specialization, which is what Adam Smith would have called the division of labor. And don't forget the division of labor is the basis of the wealth of nations. They also note other mechanisms associated to the development of agriculture that play an important economic role, like increased population growth (demand) and trade networks.

It is clear that while the preoccupation with the reproduction of the economy, which was central for the authors of the surplus approach, has disappeared from mainstream economics, is still very much alive in other branches of the social sciences.

    1. Ni todo bien con Diamond, ni todo mal con este. Ojo, igual el punto es que incorporan la noción de excedente y la preocupación con la reproducción del sistema económico.

What is the 'Classical Dichotomy'?

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…
