'''Michael Spence''' (born 1943) is an American economist who shared the 2001 Nobel Memorial Prize in Economic Sciences with [[George Akerlof]] and [[Joseph Stiglitz]] for his analysis of markets with asymmetric information. His most influential contribution is the theory of [[Signaling theory|signaling]]: the idea that in markets with hidden information, agents can use costly, observable actions to credibly reveal their private type.

Spence's canonical model, developed in his 1973 job market signaling paper, showed that education can function as a signal of worker productivity even when it confers no direct skills. If high-ability workers find education less costly than low-ability workers, then a separating equilibrium emerges where education differentially signals ability, allowing employers to distinguish types without direct observation.

The framework generalizes far beyond labor markets. Any situation where private information drives outcomes — from [[Insurance markets|insurance]] and [[Credit rationing|credit]] to [[Screening (economics)|screening]] and [[Moral hazard|contract design]] — can be analyzed through the lens of costly signaling. Spence's insight is that the signal's cost structure, not its intrinsic value, determines whether separation is possible.
