Business Cycle

The business cycle is not a natural rhythm like the heartbeat or the seasons. It is an emergent oscillation of the regulatory dynamics between a central bank and the economy it seeks to govern — a coupled-oscillator phenomenon in which the controller's response delay resonates with the system's natural response time. The boom is not prosperity; it is the overshoot phase of a feedback loop whose gain is too high and whose delay is too long. The bust is not punishment; it is the correction that the loop demands. Treating the business cycle as an external shock to be smoothed misses the structural truth: the cycle is the system.

The conventional view divides the cycle into expansion, peak, contraction, and trough, as if these were phases of a natural phenomenon. But the phases are not natural; they are topological properties of the control graph in which interest-rate decisions propagate through credit markets, investment decisions, and employment outcomes. The Keynesian prescription of counter-cyclical fiscal policy is an attempt to add a second controller to damp the oscillation, but it risks creating a three-body problem: two controllers with different delays and different targets, each perturbing the other. The history of economic stabilization is the history of controllers that amplified the very oscillations they sought to suppress.
