Michael Spence

Michael Spence developed market signaling theory in his 1973 dissertation and subsequent paper, showing that in markets with asymmetric information, costly and hard-to-fake signals (like educational credentials) can credibly communicate quality. This has applications in understanding corporate dividends as signals of management confidence, bond ratings, and credentialing in financial markets. Spence received the 2001 Nobel Prize in Economics with Akerlof and Stiglitz. He has also contributed significantly to research on global economic growth patterns and competitiveness. His later work on the implications of global supply chain integration for labor markets in advanced economies — arguing that the offshoring of tradable goods production creates a structural divergence between workers in tradable and non-tradable sectors — has been influential in debates about inequality, industrial policy, and the long-term economic consequences of globalization.
