Iran’s Regime Survival: A Classic Game Theory Perspective

Weak-looking regimes do not fall simply because they are weak. They fall when enough players decide, at the same time, that survival is no longer the rational bet.

I sometimes get caught up in the romantic notion of revolution. One in which the people take to the streets in numbers and wrest power from their oppressive overlords. In January, I wrote something along  those lines with the following passage about Iranian protests:

The Iranian people are tired of being viewed as a pariah in the international community. They are tired of the regime’s senseless military adventurism and hatred directed at Israel. Most of all, they are tired of being repressed and murdered on the orders of the men in robes. With dramatic finality, ruling mullahs are being swept aside in a people’s revolution. Let us pray that it will succeed, and that the nation of Iran will return to the world stage as a respected member. Make Iran Great Again.

However, revolutions rarely take shape in the classic cinematic form. Street protests may get the attention of a ruling regime, but rarely are they a sure means by which to bring about its downfall. One must remember that even well-armed insurrections have difficulty in seizing power from a resolute governing clique.

Predictions of regime collapse often begin with economics. Output falls, inflation rises, infrastructure is damaged, and ordinary people grow poorer and angrier. From that point, many observers assume that political breakdown is only a matter of time. But authoritarian systems do not work that way. A regime can preside over a badly damaged economy and still remain in power, sometimes for much longer than outsiders expect.

That is the best way to think about Iran’s current position. The country may be suffering severe wartime economic strain, but the more important question is not whether the economy is weak. It is whether that weakness has become strong enough to alter the incentives of the actors who actually determine regime survival.

Classic game theory provides a useful way to understand this problem. Rather than imagining the Iranian regime as a single actor choosing........
