The Business Cycle Has a Political Factor Economists Leave Out

Explanations of the business cycle are numerous and mutually incompatible. Productivity fluctuations, monetary policy errors, credit expansion, technological shocks, animal spirits, changing markets — each school has its mechanism, and the data are compatible with several of them at once.

What is largely missing from the list is politics. Not politics as a source of policy errors, which everyone includes, but politics as a structural participant in the cycle itself.

The Mechanism

Start from something Olson established: minorities with concentrated interests have both the motive and the means to extract from a diffuse majority. Extraction runs through several channels — proximity to government and the allocation of funds, or the financial system, or regulatory advantage.

Now add the part that generates a cycle rather than a steady drain. Periodically, the extraction overreaches.

The interesting thing is that the extracting minority usually knows this. They are not fools; they can see the cliff. But knowing does not stop them, because by the time the overreach is visible, the process has acquired its own constituency.

Why Knowing Does Not Help

Take a speculative run in assets with no real backing.

The people already trading are hiring more brokers. They are opening more offices, taking on more analysts, drawing larger bonuses, building management firms whose entire business is servicing this activity. Careers have been staked. Mortgages have been taken out against expected commissions.

The continued existence of whole organisations now depends on the activity continuing, entirely independently of whether the activity corresponds to anything real.

Some individuals inside these firms certainly understand that the thing is unsound. That understanding has no traction. An analyst who calls the top is not thanked; he is a drag on the desk's numbers, and he is replaced by someone less troubled. The organisation is not a mind that can change; it is a set of commitments that must be serviced.

Why the Brake Fails

So the halt must come from outside. And the only outside force with the authority is the political system — which bends instead.

Stopping a boom is politically suicidal. Nobody is thanked for ending a period of rising prices and easy credit before it ends by itself. The costs of stopping are immediate, concentrated, and attributable to you by name; the benefits are diffuse, deferred, and invisible, because they consist of a crash that now never happens and therefore never appears in anyone's ledger.

This runs at two levels. Individually, our system selects for people who are afraid to do the unpopular right thing — that is what winning elections rewards. Structurally, the system as a whole is porous to pressure from exactly the industries that most want the boom to continue, and those industries fund the campaigns.

The 2008 case is instructive. Proposals to limit mortgage availability were floated and rejected before the crash, and the reason given by the Clinton administration was explicit: they did not want to stop the boom. That was not an oversight or an analytical failure. It was the system correctly reporting its own incentives.

What It Implies

The picture is a system that cannot regulate itself. It can see the cliff — plenty of participants see the cliff — and it cannot stop, because every agent capable of stopping it is embedded in the arrangement that profits from continuing.

If that is right, then the braking force has to come from somewhere structurally insulated from those pressures. Not from a regulator staffed by industry alumni, and not from legislators funded by the industry, and not from within the firms themselves.

That is an argument for locating the brake outside the representative system entirely — a public that votes directly on the question and, crucially, has no career riding on the answer. Whether that public would exercise the brake well is a fair question. But it is at least a body whose incentives are not structurally aligned with letting the thing run.
