Socialism Succeeding In Emilia-Romagna

Emilia-Romagna is a region in Italy, north of Tuscany. I have written about its capital, Bologna, before.

About a third of the gross domestic product of Emilia-Romagna is produced by co-operatives. About two thirds of those who reside in Emilia-Romagna participate in co-ops in some ways. (See this article from John Duda.) Apparently, co-ops in Italy go back to the nineteenth century, surviving through the fascists in the twentieth century.

Article 45 of the 1947 Italian constitution promotes co-ops. It states:

The Republic recognises the social function of co-operation of a mutually supportive, non-speculative nature. The law promotes and encourages co- operation through appropriate means and ensures its character and purposes through appropriate checks.

The law safeguards and promotes the handicrafts.

A capability for a worker to take unemployment benefits at once to set up a co-op is one of the provisions of the 1985 Macora law.

A society with a large co-operative segment will have related institutions. Co-ops will market to each other. Scholars, such as Vera Zamagni at the University of Bologna, will study them. Competition among co-ops might be less cut-throat. The study of management and administration at academic institutions will have curriculum supporting co-ops. Mutual banks might be set up to loan to co-ops, and other financial institutions will have more practice in making such loans. Co-ops might set up institutes to perform research into processes and products improving their technology.

The 1986 book, The Second Industrial Divide: Possibilities for Prosperity, by Michael J. Priore and Charles Sabel, is supposed to be of interest on this topic.

Anomalous Switch Points

I have a new working paper at the Centro Sraffa. The abstract follows:

Abstract: This article presents examples of models of rent with decreasing wage frontiers; with unique, square cost-minimizing techniques at a given rate of profits; but without the wage maximization property. Anomalous switch points are highlighted, where an anomalous switch point has properties that contrast with generic switch points in models of circulating capital. This article presents a numeric example of a switch point along a single wage curve, with no other wage curve intersecting at the switch point. Other numeric examples are of switch points in which only the scale, not the operated processes, vary between the cost-minimizing techniques at the switch point. A fake switch point is presented in which prices vary only for goods which are not commodities under the non-cost minimizing technique, also known as ghost commodities.

The Roosevelt Dime And Fluoridated Water: Communist Plots

Franklin Delano Roosevelt died in 1945, and World War II ended with the Japanese surrender in August. Germany had surrendered in May. The Roosevelt dime was introduced in 1946. John Sinnock, an artist at the mint, designed the obverse. His initials are under Roosevelt’s head.

The Soviet Union was the ally of the United States in fighting the fascists. This quickly changed. Somehow anti-communists became convinced that the J. S. on the Roosevelt dime stand for Joseph Stalin. I don't know what advantage the communists were supposed to get out of this plot.

When I first saw Dr. Strangelove, I thought the idea that fluoridated water was a communist plot was quite comic. I did not realize that Kubrick did not make this up. Anti-communists believe this. I do not know if they talk about, "Sapping our precious bodily fluids," as General Jack D. Ripper does in the movie.

I have documented some other stupid stuff anti-communists and anti-Marxists have said.

On Building On Pasinetti's Lectures On The Theory Of Production

I have been re-reading Pasinetti's 1977 book. I claim I am original in partitioning parameter spaces with fluke switch points, concrete numerical examples, certain diagrams for visualizing certain analyses, and extending the capital critique to non-competitive markets. I have noted that participants in the 1966 QJE symposium, including Pasinetti, explicitly noted the possibility of fluke switch points.

Pasinetti’s Lectures contain:

• The algebra repeated in my derivation of Hayek's triangle (p. 91, p. 118).
• An explanation of how a switch point can occur along a single wage curve. The numeraire is a basic good. Two techniques differ in the method or process for producing a non-basic good (p. 161).
• A fluke case with three or more wage curves intersecting at a switch point (p. 164).

The first is an elaboration of Sraffa's reduction to dated labor quantities. I do not feel obligated to cite Newton when I take a derivative. This reduction is close to that. I do not see others linking up this analysis to Hayek's triangles, though,

Pasinetti does not provide a figure or numeric example illustrating the second point. Land is non-basic. Perhaps I should note this in my example with fixed capital and rent.

Pasinetti does provide a figure with three wage curves intersecting in a single switch point. But citing articles from 1966 is sufficient.

C129.4r: Harcourt on Translation Of Sraffa (1925)

This letter is from G. C. Harcourt to Piero Sraffa. As I understand it, Sraffa later refused permission for this translation to be published while he was alive. The translation now available is from Alessandro Roncaglia and John Eatwell.

Dear Piero,

Just a short note to say how delighted I was that you will let Mario Nuti translate the Italian version of your 1926 article for Australian Economic Papers. We will, of course, honour strictly your conditions. It really is very generous of you and I personally am extremely grateful.

I hope to be in Cambridge next January for 4 – 6 weeks and hope very much that we may meet then. I hear from Vincent from time to time, he seems to be flourishing. I have just come back from three marvellous months in Japan. I wrote a book on capital theory while there, expanding the assertions of my survey article into, I hope, persuasive arguments.

With all good wishes,

Yours ever,
Geoff. [Handwritten]

Some Cambridge Controversies in the Theory of Capital is the book Harcourt mentions writing while visiting Japan. I do not know who Vincent is.

Instability, A Problem For The Theory Of Supply And Demand

General Equilibrium Theory (GET) is the most rigorous and most developed version of the theory of supply and demand. More than half a century ago, economists discovered that GET does not support the just so stories many economists still tell. (Experimental economists have validated Scarf's example of instability.)

Franklin Fisher was an authority on this topic.

"Yet the very power and elegance of equilibrium analysis often obscures that it rests on a very uncertain foundation. We have no similarly elegant theory of what happens out of equilibrium, of how agents behave when their plans are frustrated. As a result, we have no rigorous basis for believing that equilibria can be achieved or maintained if disturbed. Unless one robs words of their meaning and defines every state of the world as an 'equilibrium' in the sense that agents do what they do instead of doing something else, there is no disguising the fact that this is a major lacuna in economic analysis.

Nor is that lacuna only important in microeconomics. For example, the Keynesian question of whether an economy can become trapped in a situation of underemployment is not merely a question of whether underemployment equilibria exist. It is also a question of whether such equilibria are stable. As such, its answer depends on the properties of the general (dis)equilibrium system which macroeconomic analysis attempts to summarize. Not surprisingly, modern attempts to deal with such systems have been increasingly forced to treat such familiar macroeconomic issues as the role of money." -- Franklin M. Fisher. 1987.

As far as I know, although some interesting work has been done, this gap still exists.
