Why Does The Labor Theory Of Value Work Empirically As A Theory Of Prices?

3 days ago

[embedded content]Anwar Shaikh On The Transformation Problem
Lots of empirical work shows that prices tend to be proportion to the labor embodied in commodities. My references in this
article
document this claim. Furthermore, empirical wage-rate of profits curves tend to be close to straight lines.
This is not what, say, Sraffa’ mathematical economics would lead me to expect. What explains these
surprising empirical findings?

Almost 34 minutes in, in the above video, Shaikh makes the above point about the contrast
between theory and empirical findings. He concludes with speculation, including with
comments on Bertram Schefold’s work with input-output matrices formed out of random
matrices.

I offer some speculations myself in this post. I do not have much theory to back these

Only The Super-Rich Can Save Us!

10 days ago

Neoliberals are hostile to labor unions and every other institution that would allow the vast majority of the population
to have some effect on how we are ruled.
And they have been so successful that
only the super-rich can save us, as the title
of a Ralph Nader novel a few years back had it. A couple of recent examples of journalism are about movements
of the super-rich:

Sheelah Kolhatkar writes, in the New Yorker, about Patriotic Millionaires.
Theodore Schleifer writes, in Vox, about Resource Generation.

I suspect most of the super-rich, however, are vicious, reactionary fools. Apparently,
Benjamin Page, Jason Seawright, and Matthew Lacombe provide
evidence in their recent book,
Billionaires and Stealth Politics.
I’ve read and
commented on their previous working paper.

Towards the Derivation of the Cambridge Equation with Expanded Reproduction and Markup Pricing

17 days ago

I have a new working paper.

Abstract: Does the Cambridge equation, in which the rate of profits in a steady state is equal to the quotient
of the rate of growth and the savings rate out of profits, hold in an economy with widespread non-competitive markets?
This article presents a multiple-good model of markup pricing in an attempt to answer this question. A balance equation
is derived. Given competitive conditions, this model can be used to derive the Cambridge equation. The
Cambridge equation also holds in a special case of markup pricing, with one capital good and many
consumption goods being produced. No definite conclusions are reached in the general case.

The Factor Price Frontier In The Space Of Factor Rental Prices

21 days ago

Figure 1: Real Factor Price Frontier1.0 Introduction

Carlo Milana has proposed
a new way of visualizing the choice of technique, including in the case
of reswitching. This way of describing what he has done is not neccessarily
how he thinks of it.
In this post, I describe his approach with a reswitching example, in a model
of the production of commodities by means of commodities.

2.0 Technology

Table 1 shows the coefficients of production for this example.
Coefficients of production specify inputs per unit output.
Each process takes a year
to complete. Inputs are totally used up in the production of the outputs.

Welcome

27 days ago

I study economics as a hobby. My interests lie in Post Keynesianism, (Old) Institutionalism, and related paradigms. These seem to me to be approaches for understanding actually existing economies.The emphasis on this blog, however, is mainly critical of neoclassical and mainstream economics. I have been alternating numerical counter-examples with less mathematical posts. In any case, I have been documenting demonstrations of errors in mainstream economics. My chief inspiration here is the Cambridge-Italian economist Piero Sraffa.In general, this blog is abstract, and I think I steer clear of commenting on practical politics of the day.I’ve also started posting recipes for my own purposes. When I just follow a recipe in a cookbook, I’ll only post a reminder that I like the recipe.Comments

2019 Nobel Prize Celebrating The Triumph Of Institutionalism?

December 26, 2019

[embedded content]Elizabeth Warren Echoing A View Institutionalists Understand
This year, the "Nobel prize" in economics went
to Abhijit Banerjee, Esther Duflo, and Michael Kremer. They champion empirical economics over theory. Previously, institutionalist
economics was described as ‘theory without measurement’ (Koopmans 1947). Does
institutionalist economics
parallel the supposed
mainstream empirical turn?

Although institutionalists, as far as I know, did not have the resources to create
randomized control trials (RCTs), they did collect and analyze statistical data.
I think especially of
Wesley Clair Mitchell
and the National Bureau of Economic Research (NBER).

Institutionalists was not atheoretical, I think. They developed qualitative analytical concepts.

A Fake Switch Point in an Example With Circulating Capital

December 14, 2019

Figure 1: A Switch Point and a Fake Switch Point on Wage Curves1.0 Introduction

In the analysis of the choice of technique, I typically consider examples of technology with a finite number of
techniques. For each technique, I find the wage as a function of the rate of profits. The outer
envelope of these curves shows the cost-minimizing technique at each rate of profits (or each level of the
wage). Points on more than one wage curve are switch points.

This approach is valid when, for example, all techniques produce the same set of commodities,
and each commodity is basic, in the sense of Sraffa. That is, all commodities enter directly or
indirectly into the production of all commodities.

But another requirement is that prices of all commodities in common between two techniques

The Interest Rate: Prime, Overnight, Or The Rate On T-Bills

December 10, 2019

As far as I am concerned, cost-push inflation is a
manifestation
of class conflict between workers and owners.
In the late 1970s, Paul Volker and Ronald Reagan took the side of the owners.
I am willing to accept that Volker genuinely believed in Milton Friedman’s
incorrect
quantity theory of money. And, since then,
workers have been getting a smaller
share
in increased productivity.
Some obituaries of
Paul
Volker
exhibit an understanding of what he did.

But I want to talk about my recollection of how interest rates have been covered in the
press from that time. Of course, at any given time, there are a whole range and time
structures of interest rates. When Volker drove the interest rate
above 20 percent, the focus in news coverage was, as I recall it, on the prime
rate, that is, the

The Cambridge Equation, Expanded Reproduction, and Markup Pricing: An Example

December 6, 2019

1.0 Introduction

I have sometimes set out Marx’s model of
expanded reproduction,
only with prices of production instead of labor values.
I assume two goods, a capital good and a consumption good, are produced with constant technology.
If one assumes workers spend all their wages and capitalists save a constant proportion of
profits, one can
derive
the Cambridge equation in this model.

The Cambridge equation shows that, along a steady state growth path, the economy-wide rate of profits
is determined by the ratio of the rate of growth and the saving rate out of profits.
Maybe one should not use causal language here. The Cambridge equation is a necessary,
consistency condition for smooth reproduction in a capitalist economy.

This post derives the Cambridge equation with markup

Literature Distinguishing Large Corporations And Finance From Competitive Firms

November 23, 2019

A considerable body of literature has been published, during the last century, arguing that a movement away from competitive
markets must be recognized in trying to describe and understanding contemporary capitalism. The literature I am thinking
of emphasizes big business, corporations, and finance. Here are some selections, not all of which I have read:

The Rate of Profits is Not the Scale Factor

November 15, 2019

Figure 1: Rate of Profits Unequal to Scale Factor for Rate of Profits
This post continues the example in the previous
post.
I modify the prices equations so that the rate of profits in producing corn
is (s1 r̂), and the rate of profits in producing ale
is (s2 r̂). The solution to the price equations are:

pcorn = 16 [16 + (s1 – s2) r̂]/[204 + (3 s1 + 9 s2) r̂]

pale = 32 [10 – (s1 – 3 s2) r̂]/[204 + (3 s1 + 9 s2) r̂]

w = 4 [51 – (9 s1 + 5 s2) r̂ – s1s2 r̂2]/[204 + (3 s1 + 9 s2) r̂]

where r̂ is what I have been calling the scale factor for the rate of profits.

I want to show that, only in exceptional cases can the the markups s1 and s2 be rescaled
such that the scale factor is equal to the economy-wide rate of profits, whatever the distribution of income.
For concreteness,

An Example Of The Labor Theory Of Value

Figure 1: Variation of Prices of Production with Wages and Markups1.0 Introduction

This post documents an example in my working paper,
The Labor Theory of Value and Sraffa’s Standard Commodity with Markup Pricing.

Consider a simple economy in which corn and ale are each produced from inputs of labor, corn, and ale.
Inputs for unit outputs are shown in the columns in Table 1. Obviously, the units of measure should not

of fixed capital, land, and joint production.

The Labor Theory of Value and Sraffa’s Standard Commodity with Markup Pricing

October 23, 2019

I have uploaded a
working paper
with the post title.

Abstract: This article demonstrates relationships that are transparent in Sraffa’s
standard system hold even when relative rates of profit vary persistently among industries.
Even with such variations, total constant capital, total variable capital, total surplus value,
and the rate of profits are unaltered by evaluation at labor values and at prices of production
in Sraffa’s standard system. These results buttress those who see in the standard commodity
a solution for Marx’s so-called transformation problem.

Actually Existing Socialism In A Capitalist Setting?

Elements of a post capitalist society are and have been

Structural Economic Dynamics and Fake Switch Points

This post completes an example. I analyzed bits of this example
here and
here.
This post may make no sense if you have not read a long series of previous posts
or, maybe, the papers highlighted

I am interested in how and if my approach to analyzing and visualizing variations in the choice
of technique with technical progress extends to joint production. The example suggests fake switch points
do not pose an insurmountable obstacle for such an extension.

of firms know of three processes (Tables 1 and 2) to produce corn

Variation in Standard Commodity with Relative Markups

September 28, 2019

I am not sure about the economic logic in this post. Maybe somebody like D’Agata or Zambelli could do
something with this. These ideas were suggested to me by email with a sometime commentator.

I start out with notation for Sraffa’s price system, modified in an unusual way to
allow for persistent variations in the rate of profits among industries:

a0 is a row vector of labor coefficients in each of n industries.
A is a Leontief input-output matrix, where ai, j
is the quantity of the ith commodity needed as input to produce one unit of the jth commodity.
S is a diagonal matrix, where all off-diagonal elements are zero. sj, j is
the markup on non-labor costs in the jth industry.
p is a row vector of prices.
w is the wage.
r is the scale factor for the rate of profits.

A Fluke Case Over The Wage Axis

September 21, 2019

Figure 1: Wage Curves and The Price of Corn for the Fluke CaseIntroduction

This post extends a
previous post.
I am basically introducing structural dynamics into an example, by Bidard and Klimovsky of fake switch points.

At a rate of profits of zero in the example, the price of corn is zero for Alpha, one of the two techniques
that is cost-minimizing there and for somewhat higher rates of profits. At a time before the fluke
case, only the Gamma technique is cost-minimizing at a rate of profits of zero. The price of corn,
as calculated with the Alpha technique, is negative at a rate of profits of zero.
Alpha prices become non-negative only for positive rates of profits. This possibility cannot
arise in examples with only single production and the choice of technique analyzed by the

A Pattern Over The Wage Axis In A Case Of Joint Production

September 16, 2019

Figure 1: Wage Curves with Corn as Numeraire1.0 Introduction

This post presents an example of a fluke switch point in which the choice of technique cannot be analyzed
by the construction of the wage frontier. Under joint production, the technique that is cost-minimizing,
for a given rate of profits, does not necessarily maximize the wage. Nevertheless, one can still see
what I call a pattern over the wage axis in this case. The example is a generalization of
the numerical example in Bidard & Klimovsky (2004).

2.0 Technology

I postulate an economy in which two commodities, corn and linen, can be produced from inputs of corn, linen, and labor. Managers
of firms know of three processes (Tables 1 and 2) to produce corn and linen. Each process produces net outputs of corn and

Martin Weitzman’s The Share Economy

September 7, 2019

I happen to have one book by Marty Weitzman (1942 – 2019) on my bookshelf. So I thought I would write a bit about
The Share Economy: Conquering Stagflation.

This is an ill-timed book. It proposes that firms negotiate with workers to pay them a percentage of revenues,
instead of, say, an hourly money wage.
It argues that such a change will address the widespread macroeconomic problem,
throughout the 1970s, of simultaneously high unemployment and high inflation. But, by the time the book came out, stagflation had been "solved", in
an extremely reactionary way.
The countervailing
power
of organized labor
was being abolished. Labor unions were being crushed, and workers would, by and large,
no longer see their wages increase with productivity. Instead of unemployment being addressed,

Mass Publics Apathetic About Democratic Norms?

Economists Insulting Me And Insulting Keynes

I happen to think the minimum wage in the United States should be raised. I’ll go along with the
consensus of $15 an hour.

I also happen to
know
that, even under ideal conditions, wages and employment cannot be
explained
by supply and demand.

Some economists, who I no (other) reason to disrespect, seem to think my true statement about labor
economics can be discredited by
attacking my motivations.
So they point out how, under (incoherent) neoclassical theory, higher minimum wages can be justified
by, for example, the theory of monopsony.
But my motivations are almost the opposite.

of mainstream economics.

Reswitching, Recurrence, And The Incoherence Of The Marginal Productivity Theory Of Distribution

August 17, 2019

Blair Fix argues that economists
argue in a circle in putting forth the marginal productivity theory of distribution.
I know that there is no such consistent theory anyways. It occurs to me that
process recurrence, as well as the reswitching of techniques, can be used to demonstrate this
inconsistency.

Suppose you completely know the technique being used in an economy to produce its output. And,
which is even more impossible, you know all other possible techniques. I am thinking of
a technique being specified with something like a Leontief input-output matrix, in
physical terms. Assume, counterfactually, that all these techniques exhibit constant
returns to scale. With these assumptions, you know the physical marginal product
of each input into production, whether it is previously

Structural Economic Dynamics And Reswitching In A One-Good Model

August 6, 2019

This post, as suggested, extends this
one-good example. I assume a constant returns-to-scale technology, as specified in Tables 1 and 2. Labor is advanced to the capitalists,
and wages are paid out of the surplus at the end of the year (period of production). The capitalists (incorrectly) expect the technology in
existence at the start of the year to continue to exist. I assume prices of (re)production prevail.

Around some switch points, higher wages are associated with greater employment, given the level of net or gross output
