This may be surprising to non-Economists, but mainstream economic theories describe a world where money plays a marginal and unimportant role. This is called the doctrine of neutrality of money. My writings on money — see GUIDE: The Veiled Power of Money — are organized into a sequence of seven hubs. This post is the first HUB which provides a guide to my posts and writings discussing this issue, and the reasons why money is marginalized in economic theories. For a related post, explaining that the key difference between mainstream and heterodox economic theory lies in the role assigned to money, see: Economics As If Money Mattered.

1. The Astonishing Claim

“In this model, the effects of monetary policy are so insignificant that postal economics is more central to understanding the economy than monetary economics.”
— Edward Prescott (see: Romer’s Trouble With Macro)

Prescott was referring to Real Business Cycle (RBC) models — a highly influential strand of modern macroeconomics in which output, employment, and growth are determined by technology and preferences. In these models, money may affect prices, but it does not determine real economic outcomes.

And yet modern economies run on money.

Banks create it.
Governments depend on it.
Asset markets move with it.
Financial crises erupt when it contracts.

Ordinary people assume economics is about money. But much of modern macroeconomic theory is built on a sharp distinction between “real” and “nominal” variables — a framework in which production and employment are governed by real forces, while money is treated as a secondary layer over an underlying exchange economy. For more details, see Nominal Versus Real Models.

The result is striking: the central institution of modern capitalism is largely absent from its core models.

As the heterodox economist Steve Keen has put it (see: Quotes Critical of Economics):

“How anybody can think they can analyze capital while leaving out Banks, Debt, and Money is a bit to me like an ornithologist trying to work out how a bird flies whilst ignoring that the bird has wings.”

Between Prescott’s formal neutrality and Keen’s metaphor lies a puzzle.
How did economics come to analyze modern capitalism as if money were incidental?

To answer that question, we must begin with an old and powerful idea: that money is merely a veil.

2. The Veil Doctrine

The idea that money is secondary to “real” economic activity has deep roots. Classical economists described money as a veil: behind it lies the real economy — production, labor, technology, exchange. Money merely facilitates trade; it does not determine outcomes. For more details, see: Looking Through the Veil of Money.

This intuition became formalized as the classical dichotomy: a separation between real variables (output, employment, productivity) and nominal variables (prices, wages, money). In this framework, money affects prices but not the real structure of the economy.

The Keynesian Revolution challenged this separation. Keynes argued that excessive money leads to inflation, while insufficient demand — and insufficient monetary expansion — leads to unemployment. This gave governments a central role in stabilizing economic activity. In the decades following World War II, Keynesian policies, combined with strong financial regulation, coincided with sustained growth, high employment, and rising income shares for the bottom 90 percent in Western economies.

Financial regulation after the Great Depression had already constrained speculative banking. When combined with demand management policies, the result was a prolonged period in which the power of the financial sector was limited relative to labor and industry.

The monetarist counter-revolution, associated most prominently with Milton Friedman, rejected Keynesian demand management and restored the classical emphasis on monetary neutrality. The Quantity Theory of Money gave this view its most famous expression: “inflation is always and everywhere a monetary phenomenon.” In this framework, money determines prices; real output is governed elsewhere. For a detailed discussion, see The Keynesian Revolution and the Monetarist Counter-Revolution.

As Keynesian policies were dismantled in the Reagan–Thatcher era, financial deregulation accelerated. The repeal of Glass–Steagall (1999) and the Commodity Futures Modernization Act (2000) expanded the scope of financial activity and contributed to the rise of shadow banking and shadow money. Over the same period, labor’s share of income declined while the share accruing to the top percentile rose. For a visual demonstration and discussion, see The Power of Economic Theory: Graphically Illustrated.

The historical record shows that economic doctrines do not ascend by argument alone. They are cultivated, funded, institutionalized, and strategically disseminated — often with support from those whose material interests they reinforce. For a discussion of how organized intellectual strategy shapes economic paradigms, see Romer’s Trouble with Macro.

The methodological debate within Economics focuses on the normative positive distinction, and typically asserts that Economics is positive – that is it describes the world around us. It is not normative – it does not describe what should be, or the ideal state Both of the labels miss the boat. Economics is actually performative: It shapes economic policies and institutions, and the economic realities of our lives.

Treating economics as an objective description of reality, and veiling the role of money, makes financial power structurally invisible, and is greatly beneficial to those who wield that power.

3. Two Logics of Economic Life

The neutrality of money persists because modern economics makes a prior modeling choice — rarely acknowledged.

As Marx observed, there are two fundamentally different logics of economic life.

The first is the logic of exchange:

Commodity → Money → Commodity (C–M–C′)

Goods are produced to obtain other goods. Money is a convenience — a bridge between commodities. Once exchange is complete, money drops out. Welfare is measured in consumption. In such a world, money does not drive the system; it merely lubricates it.

This is the architecture of most modern economic models. Arrow–Debreu general equilibrium theory is, in essence, a refined barter system. Utility maximization assumes that agents ultimately seek goods. Even profit maximization is translated into real magnitudes. Money sits on top of the “real” economy as a layer — not as a foundation.

But modern capitalism does not operate this way.

Its logic is different:

Money → Commodity → More Money (M–C–M′)

Money is not a bridge. It is the objective. Corporations invest to expand capital. Banks create credit to earn returns. Financial institutions measure success in monetary terms. Production becomes a vehicle for accumulation. Balance sheets, leverage, and liquidity are not side details — they are structural.

In an M–C–M′ system, money cannot be neutral. It organizes production, employment, and survival.

If we analyze an M–C–M′ economy using C–M–C′ assumptions, money will appear secondary by construction. The model has already decided that consumption is the goal and accumulation is incidental. (For a deeper discussion, see The Great Transformation of Economic Theory.)

Modern economics continues to describe capitalism as if it were an exchange system. It is not. It is a monetary production system.

Once that is recognized, the central questions change: Who creates money? Who directs credit? Who absorbs losses? Who decides which sectors expand and which collapse?

Those are the questions we turn to next.

4. Crisis, Debt, and Power

The Global Financial Crisis of 2008 did not begin with a productivity shock. It began with a collapse of mortgage credit and shadow banking. When credit stopped expanding, spending collapsed. Unemployment followed.

The economics profession was blindsided. The dominant models contained no meaningful role for banks, household balance sheets, or financial fragility. Financial intermediation was treated as a friction; debt was largely absent. As John Cassidy documented in “After the Blowup” , even as markets imploded, leading defenders of efficient markets struggled to fit events into their existing frameworks.

This was not a minor forecasting error. It was a structural blind spot.

The work of Atif Mian and Amir Sufi in House of Debt showed that regions with higher household leverage experienced deeper collapses. Consumption fell where debt burdens were greatest. The crisis was transmitted through household balance sheets — variables largely invisible in mainstream macroeconomic models. (For discussion, see: Why Does Aggregate Demand Collapse?)

But there is a deeper layer. As David Graeber argues in Debt: The First 5000 Years, debt is not merely a financial contract; it is a moral and political relationship. A debt-driven growth model shifts risk onto households while concentrating control over credit in financial institutions. High household indebtedness is not only macroeconomic fragility; it is an index of financial power. Indebted populations are economically disciplined populations.

If money were neutral, banking crises would not destroy employment. If debt were incidental, household leverage would not determine the depth of recessions. The GFC demonstrated that money and credit are not side details of capitalism — they are structural.

Once this is recognized, neutrality is no longer an innocent abstraction. It obscures the central mechanism through which modern economies expand, contract, and distribute power.

Which brings us to the unavoidable question: Who creates money?

5. Rebuilding Economics: An Invitation to a New Generation

The Global Financial Crisis did not simply expose a policy failure. It exposed a theoretical failure. Adding “financial frictions” to existing models does not solve the problem if the core architecture still treats money as secondary.

If capitalism is a monetary production economy, then macroeconomics must begin with money, credit, balance sheets, and institutional structure — not with representative agents maximizing utility in an abstract exchange world.

This is not a minor adjustment. It is a research frontier.

For students choosing MPhil or Ph.D. topics, the open questions are vast and urgent:

• How does bank credit shape sectoral development?
• How do household balance sheets transmit shocks?
• What determines the allocation of liquidity across classes and regions?
• How does monetary hierarchy shape global inequality?
• How does rising household debt alter labor markets and political agency?
• What institutional designs reduce financial fragility without suppressing productive investment?

These are not ideological questions. They are analytically demanding, empirically rich, and largely underdeveloped within mainstream frameworks.

A monetary economy requires a different methodology. Accounting identities are not bookkeeping constraints added at the end; they are the starting point. Balance sheets are not side details; they are the structure of the system. Institutions are not frictions; they are the architecture.

Paradigm shifts do not occur because established scholars are persuaded. They occur because new researchers choose different starting points.

You do not need to defeat the old framework. You can build the next one.

A monetary production economy requires a monetary economics. The task is not to repair the old structure. It is to construct what comes after it.
