The Game Theory Behind Taiwan

I’ve long been a student of game theory, the branch of mathematics that studies how rational actors make decisions when their outcomes depend on what everyone else does. It’s a helpful framework for understanding markets and geopolitics, and right now, there’s no better place to apply it than Taiwan.

The stakes couldn’t have been higher this week as President Trump met with Chinese leader Xi Jinping in Beijing. Xi reportedly warned Trump that “conflicts” could emerge if the two powers mishandle Taiwan.

Meanwhile, Taiwan’s legislation just approved $25 billion in special defense funding. The U.S. cleared an $11 billion arms package last December, with another $14 billion package reportedly waiting in the wings.

Chicken on the World Stage

There’s a famous scenario in game theory called the game of Chicken. Two drivers race toward each other head-on. The one who swerves first loses face but survives. If neither swerves, both are destroyed. The dilemma is that each player wants the other side to blink first, but the cost of miscalculation is catastrophic.

That’s precisely what’s at stake across the Taiwan Strait.

China believes reunification with Taiwan is inevitable. Xi perceives the island as the “core of China’s core interests,” and Beijing has never taken the use of force off the table.
