Economists Insulting Me And Insulting Keynes

21 hours ago

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.
I take the evidence
that neoclassical economics is wrong about labor markets as a launching into the illogic
of mainstream economics.
(Is this
the most recent meta-analysis on minimum wages?)

The attack,

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

7 days ago

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

18 days ago

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.

Structural Economic Dynamics, Markups, Real Wicksell Effects, And The Reverse Substitution Of Labor

25 days ago

I am being published
in Structural Change and Economic Dynamics. Currently, this link is without my corrections to proofs, I guess.

Research highlights:

Technical progress and variations in industry markups can change characteristics of the labor markets.
A numeric example illustrates the theory of the choice of technique.
In the example, switch points are created and destroyed with varying coefficients of production and varying markups.
Around some switch points, higher wages are associated with greater employment, given the level of net or gross output
Graphical displays are provided for visualizing these results.

Abstract: This article presents an example in which perturbations in relative markups and
technical progress result in variations in characteristics of the labor market.

No Such Thing As The Natural Rate Of Unemployment

July 23, 2019

I know that the idea of a "natural rate" of unemployment or a
non-accelerating inflation rate of unemployment (NAIRU)
makes no
sense.
I cite, for example, James Galbraith’s 1998 book,
Created Unequal: The Crisis in American Pay.
I think Colin Rogers’ 1989
book is related.

Jared Bernstein
gives
the idea of a natural rate of unemployment at the first of four examples of ideas that [mainstream] economists have gotten
wrong for decades. This is not the first
example of a case where Post Keynesians
(and only Post Keynesians(?)) could explain an empirical phenomenon decades in advance.

Harrod-Neutral Technical Progress and Fluke Switch Points

July 19, 2019

Figure 1: A Pattern Diagram
I have put up a
working paper
with the post title.

Abstract: This article considers Harrod-neutral technical progress in the context of an analysis of the choice of technique.
In a model of the production of commodities by means of commodities, neutral technical change is compatible with the reswitching of
techniques, capital reversing, process recurrence, and the reverse substitution of labor. A taxonomy of fluke switch points is
applied to an example, illustrating how these phenomena can arise and vanish in the course of neutral technical progress.

I get various fluke switch points, as is typical of my examples. By assuming Harrod-neutral technical change, I
end up with the structure in Figure 2, in one slice of the parameter space.

Children, Dialectics, and Topology

July 16, 2019

"One of the curious things about our educational system, I would note, is that the better trained
you are in a discipline, the less used to dialectical method you’re likely to be.
In fact, young children are very dialectical; they see everything in motion, in
contradictions and transformations. We have to put an immense effort into training
kids out of being dialecticians."
— David Harvey, Companion to Marx’s Capital: The Complete Edition. Verso (2018).

I do not have children, and I am not sure I understand Harvey’s claim. But one writer
I liked was Jean Piaget.
(I also want to mention Seymour Papert.)

I take from him that children think in a way that can be described
by advanced mathematics. I think, in particular, of topology and
modern
algebra.
The idea is children take time to

On Milana’s Purported Solution To The Reswitching Paradox

July 4, 2019

Carlo Milana has posted a paper on arXiv. I was prepared to accept this paper’s claims. Economists have developed
price theory. Referring to Sraffian "paradoxes" and "perverse" switch points is a matter of speaking.
There does not exist separate Sraffian and neoclassical versions of price theory. For a result to be "perverse",
it need only contradict outdated neoclassical intuition. But it is as much a part of the mathematical economics
as any other result. (It is another matter that much teaching in microeconomics is inconsistent with the mathematics.)

In equilibrium, the price of the services of each capital good in use is equal to the value of the marginal product
of that good, with all prices discounted to the same moment in time. This discounting implies that the interest

[embedded content]Young Children Policing Group Members
This post presents examples of psychologists inducing stress in experimental subjects, some showing why we need Institutional Review Boards (IRBs).
Some of the older studies involved so much suffering that experimental subjects suffered Post-Traumatic Stress Disorder (PTSD). I recall
that at the end of the 1976 movie, The Tenth Level, about the Milgram experiment, starring William Shatner, the scientists are discussing what they
would do if they were experimental subjects. Would they refuse to torture others? And one says to Shatner/Milgram something like,
"It seems to me, you have already been tested and failed."

Lewin and Cachanosky on Neo-Ricardian Economics [Citation Needed]

June 17, 2019

This post is about the misrepresentation of Sraffian
capital theory in Lewin and Cachanosky (2019). I cannot
recommend this short book. Presumably, it is meant as
an introduction. But I do not see it as succeeding.
I do not see what a more advanced audience would
get out of it that is not available in a few
recent papers by Lewin and Cachanosky.

Before proceeding to my main theme, let me note that I
agree with some parts of this book, mainly where
Lewin and Cachanosky draw on Ludwig Lachmann,
to parallel themes in Joan Robinson’s emphasis
on historical time.
They state that no physical measurement of capital
exists and that capital is not a factor of production,
with a demand function.
They state, probably as influenced by Jack Birner, that Hayek never set out a coherent

On Hicks’ Average Period of Production

June 8, 2019

Figure 1: APP Around Switch Points1.0 Introduction

I take it that the Austrian theory of the business cycle builds on Austrian capital theory. The following two claims
are central to Austrian capital theory:

Given technology, profit maximizing firms adopt a more capital-intensive, more roundabout technique at a lower interest rate.
The adoption of a more roundabout technique increases output per worker.

Originally, Eugen von Böhm-Bawerk proposed a physical measure of the average period of production, but economists of the
Austrian school have been distancing themselves from this position for well over half a century. I have
argued that the
first claim fails, even in a framework without any scalar measure of capital-intensity or the average period of production.

Recently, Nicholas

Refutation Of Austrian Business Cycle Theory

June 6, 2019

Those who understand price theory reject the theory of the Austrian Business Cycle (ABC).
I am thinking here that its logical invalidity follows from post-Sraffian capital theory.
It is also wrong because of its reliance on the concept of the natural rate of interest.

Some years ago, I tried to get published a demonstration that ABC theory was in error.
I forget how many journals rejected it. Four or five articles
here
are from this series of revisions.
The rejections from the journals more sympathetic to Post Keynesians
generally said that everybody knows that ABC theory is wrong.
The rejections from the journals more sympathetic to the Austrian school
said that I ought to read more and more obscure literature.
Some of this helpful for understanding of the history of ABC theory,

Some Reviews of Quiggin’s Economics in Two Lessons

May 31, 2019

I have been thinking of posting a review of Quiggin’s book, but this is not it. I suppose I should
mention that I am in the acknowledgements.

Jorge Besada raves at the Mises Institute.
Peter Boettke on his blog.
Tyler Cowen lists Quiggin’s book in his current reading.
Diane Coyle on her blog.
David Gordon at the Mises Institute.
Richard Holden at Inside Story.
Arnold Kling on his blog.
"hayekian" raves.

Quiggin has a response to a couple of
the above. By the way, he had a paper,
in 1987, on public choice.

I think any reviewer should note that Quiggin is extremely generous to
Hazlitt’s
Economics in One Lesson. Hazlitt does not mention "opportunity cost". By focusing on this
concept, Quiggin makes Hazlitt seem more coherent than he is. I agree with Quiggin that this coherence does

All Combinations of Real Wicksell Effects, Substitution of Labor

May 25, 2019

Figure 1: A Pattern Diagram
Consider an example of the production of commodities, in which many commodities are produced within
capitalist firms. Suppose two techniques are available to produce a given net output.
These techniques use the same set of capital goods, albeit in different proportions.
They differ in process in use for only one industry. Given the qualification about
the same capital goods, generic (non-fluke) switch points are the intersection of the
intersection of the wage curves for two techniques that differ in exactly one process.

Suppose that, due to technological progress, some coefficients of production decrease
in the process unique to the Alpha technique.
Figure 1 shows a possible pattern diagram
for this generalization of a previous
example.

Alfred Eichner’s Microfoundations, Or An Open Letter To Marco Rubio

May 24, 2019

The Growing Importance of Finance in the Post-War U.S. Economy
As I understand it, Marco Rubio takes from Post Keynesians the idea that, during the post-war
golden age, investment decisions
were dominated by industrial firms. But now, they are dominated by financial corporations.
This change has been accompanied by deleterious effects on economic growth, stagnant wages, and
an upward shift in the distribution of income and wealth.
The increasing importance of finance in the economy in the United States, at least, is
illustrated by the above graph. The impact of the global financial crisis is immediately
apparent in 2008.

The distinction between having investment directed by finance or by industry
might not make any sense to you if you think of every investment as like

How To Defend Capitalism?

May 16, 2019

1.0 Summary of Defense

Last month, Mike Munger
purports
to "summarize the basic argument for capitalism" (emphasis added).
He acknowledges his argument is superficial. I find it excessively so.
Munger argues that capitalism:

Supports the division of labor
Provides price signals so as to direct production appropriately
Promotes economies to scale

Ultimately, this defense is that capitalism delivers the goods.
Here’s a well-expressed, simple defense that, partially,
argues along these lines:

It is possible to defend our economic system on the ground that,
patched up with Keynesian correctives, it is, as he put it, the
‘best in sight’. Or at any rate that it is not too bad, and change
is painful. In short, that our system is the best system that we
have got.

Or it is possible to

Positive Real Wicksell Effect, Forward Substitution Of Labor

May 7, 2019

Figure 1: Wage-Rate of Profits Curves
Consider a comparison of comparison of stationary states. Net output is taken
as given, and a unit of net output is the numeraire. Technology consists
of a finite set of techniques. In each technique, net output is produced
from inputs of labor and produced circulating capital goods. No fixed
capital is used, and land of the best quality is in such abundance that
it is free. Also assume constant returns to scale.

One can find a wage-rate of profits curve for each technique.
The cost-minimizing technique at is the technique its wage curve
on the outer envelope, also known as the wage-rate of profits
frontier, at that wage. Switch points are points at which two or
more wage curves intersect (on the frontier). Suppose the same

Some Experts On The Cambridge Capital Controversy

April 19, 2019

Many years ago, I used to argue, on Usenet, about the Cambridge Capital Controversy. Many mainstream economists
used to ignorantly assert,
when pretending to respond, that an application of the CCC to labor economics
was my idea alone. So I used to demonstrate that this was false by quoting from the literature.
As far as I can see, mainstream economists are still mostly trained into ignorance.

P. Garegnani:

"The idea that demand and supply for factors of production determine distribution has become so deeply ingrained in economic thought that
it is almost viewed as an immediate reflection of facts, and not as the result of an elaborate theory. For the same reason, it is easily
forgotten how comparatively recent that theory is. In the first systematic analysis of value and

Gramsci Should Be Difficult To Understand

April 11, 2019

Fact: If you use the word "carceral" instead of "prison" your argument immediately becomes more persuasive.

Good praxis is to use words like "praxis" that nobody understands.
— Matthew Yglesias (5 April 2019, on Twitter)

A large academic literature
exists around Antonio Gramsci’s Prison Notebooks. Topics discussed
include the relationship of civil society to the state, hegemony, the contrast between consent and
coercion, class alliances in political parties, Fordism, the contrast between a "war of position" and
a "war of movement", the contrast between organic intellectuals and traditional intellectuals, and
the concept of a passive revolution.

When writing his notebooks, Gramsci had to be concerned with Fascists guards reading them and tearing
them up in displeasure. Thus, he

The FAA Process For Certifying Flightworthy Software

April 5, 2019

1.0 Introduction

This post is on current events. The plane crashes of the Boeing 737 Max 8 airplane is
arguably
about
more than a software bug.
I point out in this post that you can read about how the United States’
Federal Aviation Administration (FAA) is supposed to certify software and electronic hardware in airplanes
yourself.
In some sense, this post is not about software bugs, but rather about software engineering certification processes that
fit into a larger systems engineering perspective.

The FAA provides lots of resources associated with DO-278C,
Software Considerations in Airborne Systems and Equipment Certification,

Arguing Against “Libertarianism”

By "libertarianism",

Should Liberals Want A Coalition With Conservatives Or Labor?

March 7, 2019

This is current events,
and but post is about current events in Britain in 1920. Lenin comments on reports of a dispute between Lloyd George
and H. H. Asquith, both leaders of the Liberal party:

[In] the speech delivered by Prime Minister Lloyd George on March 18, 1920… Lloyd George entered into a
polemic with Asquith (who had been especially invited to this meeting but declined to attend) and
with those Liberals who want, not a coalition with the Conservatives, but closer relations with the
Labour Party. (In the above-quoted letter, Comrade Gallacher also points to the fact that Liberals are
joining the Independent Labour Party.) Lloyd George argued that a coalition — and a close coalition at
that — between the Liberals and the Conservatives was essential, otherwise there might be a

“The Microeconomic Foundations of Aggregate Production Functions”

February 26, 2019

Figure 1: A Production Network
I here comment on Baqaee and Farhi (2018). I am still trying to absorb it. I suppose that it is
nice that an economist at Harvard is revisiting the Cambridge Capital Controversy (CCC).
(Where is Michael Mandler these days?)

My major criticism is they do not do what their title claims. That is, their supposed microeconomic foundations
are still up in the air.

In many CCC examples, technology
is specified in terms of fixed-coefficient production processes. Sometimes, more than one process is available
for producing a specified commodity. This structure gives rise to a choice of technique. If one wanted, one could formulate
a programming problem, in each sector, whose solution is a production function for that sector. This production
function would not be

Some Contradictions Of Capitalism

February 14, 2019

I tend to be doubtful, albeit sometimes amused, by comments drawing on Hegel. But I thought I would adopt
some of that sort of language for a post.

Capitalism constantly revolutionizes production, leading to a fantastic increase in productivity.
An ever more diverse set of commodities is produced, including for consumption.
Machines for making, controlling, and communicating with other machines, are constantly being
introduced, reducing the labor time needed to produce any commodity.

For the diversity in commodities to be sold, workers, who constitute the most part of
consumers, must develop their abilities to appreciate as much as possible. Likewise,
they must developers their capabilities to be able to change the industry in which
they work:

But if, on the one hand, variation of
