Muted by r/academiceconomics. For Asking a Mathematical Question.

A short note on the difference between technical precision inside wrong assumptions and intellectual honesty about the assumptions themselves.

---

Last week I received this message from r/academiceconomics:

No reason given. No specific post cited. No rule violation identified. Twenty-eight days of silence, issued retroactively, approximately one week after my last post in the subreddit.

I want to be fair about this. I do not know the specific reason for the mute. It may have been an automated system. It may have been a user report. It may have been a moderator decision based on posts I am not aware of. I am not claiming persecution. I am noting a fact: a subreddit called “Academic Economics” temporarily silenced someone who had been asking mathematical questions about the foundational assumptions of mainstream monetary theory.

The irony is instructive enough to be worth documenting.

1. What I Had Been Posting

My posts in r/academiceconomics were not personal attacks. They were not conspiracy theories. They were not politically motivated screeds. They were mathematical questions about two foundational frameworks of mainstream monetary economics, both of which I had engaged with seriously and cited correctly.

The first question was about Jordi Galí’s New Keynesian framework and the Equation of Exchange: MV = PQ. My observation was simple: the formula correctly describes the relationship between money supply, velocity, price level, and real output. But it omits two variables that are not negligible in a debt-based monetary system, namely taxes (T) and interest on debt (I). The corrected formula should read MV = PQ + T + I. This is not an attack on Galí. It is a mathematical observation about what the formula includes and what it excludes.

The second question was about John Cochrane’s Fiscal Theory of the Price Level. My observation was equally simple: Cochrane correctly identifies that inflation is fundamentally a fiscal phenomenon, that the price level adjusts to maintain fiscal equilibrium, and that central banks cannot control inflation without credible fiscal policy. I agreed with all of this. My question was: given that this mechanism has been operating since 1944, and given that the result has been an 87-88% loss in the dollar’s purchasing power since 1950, at what point does a mechanism that correctly manages structural insolvency become a mechanism that is itself the problem?

These are not radical questions. They are the natural next questions after reading Galí and Cochrane carefully.

2. Technically Precise Inside Wrong Assumptions

Here is the distinction I want to make clearly, because it is the most important one in this entire discussion.

Galí is technically precise. His DSGE models are mathematically rigorous, internally consistent, and extraordinarily useful for answering the questions he asks. Cochrane is technically precise. His Fiscal Theory of the Price Level is logically sound, empirically grounded, and a genuine advance over the standard monetarist framework.

The problem is not their technical precision. The problem is the boundary of what they consider worth questioning.

Galí optimizes monetary policy within a debt-based system. His models assume that money is issued as debt and then ask: given this, how should interest rates be adjusted? This is a legitimate and useful question. It is not the only question worth asking.

Cochrane explains how inflation manages the real burden of debt. His framework assumes that governments issue debt-based currency and then asks: given this, how does the price level adjust? This is a legitimate and useful question. It is not the only question worth asking.

The question neither of them asks, the question that r/academiceconomics apparently finds sufficiently inconvenient to mute, is this: should money be issued as debt in the first place?

Galí builds the most elegant possible map of the cage.
Cochrane explains most precisely how the cage manages its own weight.
Neither asks whether the cage should exist.
When someone asks whether the cage should exist, the subreddit dedicated to academic economics issues a 28-day mute.
The irony is, as I said, instructive.

3. The Lunch That No Longer Exists

Let me make this concrete with the example that neither Galí nor Cochrane includes in their frameworks.

In 1950, $10 bought a full lunch for a family of four in an American restaurant. Today, $10 buys approximately a sandwich, if you choose carefully. The dollar has lost approximately 87-88% of its purchasing power since 1950, according to official Bureau of Labor Statistics data.

Cochrane’s framework says: this is the price level adjusting to maintain fiscal equilibrium. Inflation erodes the real value of government debt, restoring the balance between outstanding obligations and expected future surpluses. The mechanism works correctly.

This is technically precise. And it describes, with perfect accuracy, how the savings of an entire generation were quietly confiscated through purchasing power erosion, without a vote, without a debate, without anyone ever asking the family that used to buy four lunches for $10 whether they consented to the mechanism.

Galí’s framework says: given the current monetary architecture, here is how to set interest rates to minimize inflation volatility. If the framework is applied correctly, inflation stays close to the 2% target, and the purchasing power erosion happens at the optimal rate rather than at a catastrophic one.

This is also technically precise. And it describes, with equal accuracy, how a 2% annual erosion compounded over 76 years produces an 87% cumulative loss — at the optimal rate. The patient is losing weight at the medically recommended pace. The patient is still losing weight.

Cochrane explains why the lunch disappeared.
Galí optimizes the rate at which it disappears.
Neither asks why the lunch has to disappear at all.
That question gets you muted for 28 days.

4. The Incentive Structure, Not the People

I want to be precise about what I am and am not arguing, because precision matters and because there are serious, honest people working within academic economics who deserve not to be caricatured.

I am not arguing that academic economists are stupid or corrupt. Galí and Cochrane are not stupid. They are among the most intellectually serious people working on these questions. The participants of r/academiceconomics are not corrupt. They are students and researchers trying to understand a genuinely complex field.

What I am arguing is that the incentive structure of academic economics, specifically the funding sources of research, the criteria for publication in top journals, the basis on which Nobel prizes are awarded, and the definition of what counts as “academic” versus “fringe,” is systematically structured to reward questions asked inside the existing monetary architecture and to discourage questions about the architecture itself.

This is not a conspiracy. It is an incentive structure. Institutions fund research that validates their existence. Central banks fund economics departments that produce frameworks for better central banking. The Sveriges Riksbank funds a prize that rewards economists who improve the management of debt-based monetary systems. The result is not suppression. It is selection, the quiet, continuous, career-shaping selection of which questions are worth asking and which are not.

When someone from outside the selected set of questions shows up in a subreddit and asks “but should money be issued as debt at all?” the response is not necessarily intellectual hostility. It may simply be genuine incomprehension. The question does not fit the framework. It does not have a place in the taxonomy of things worth discussing. And so it gets muted, not out of malice, but out of the same structural logic that produces the framework in the first place.

5. What the 28 Days Will Be Used For

I cannot post in r/academiceconomics for 28 days. This is, in the scheme of things, a minor inconvenience. The publiccashmoney.com server is running. The 40+ articles are there. The mathematical arguments have not changed. The $39 trillion has not decreased. The 87% purchasing power loss since 1950 has not been restored.

The 28 days will be used to continue writing. To continue verifying data. To continue asking the question that apparently warrants a temporary mute from the subreddit dedicated to the academic study of economics: should money be issued as debt in the first place?

The question will still be there on day 29. So will the data.

Galí: technically precise inside the cage.
Cochrane: technically precise about how the cage manages its weight.
r/academiceconomics: temporarily muted the person asking
whether the cage should exist.

In 1950, $10 bought lunch for four.
Today it buys a sandwich.
The mechanism worked correctly.
The lunch is still gone.

I will be back on day 29 With the same question and the same data.

$2+2=4. Period.
