George Stigler
Citation: For his seminal studies of industrial structures, functioning of markets and causes and effects of public regulation.
The key idea
Information is costly. Markets and regulation should be analysed as the outcome of rational behaviour by participants — including regulators, who are 'captured' by the industries they oversee.
The explanation
Stigler's 1961 'Economics of Information' showed that price dispersion in markets is a rational response to search costs. His 1971 'Theory of Economic Regulation' argued that regulation is supplied to industries that demand it — incumbents seek regulation to entrench position, regulators are captured by repeated interaction.
Why Africa should care
Regulatory capture is endemic across African telecoms (single dominant players), banking (oligopolistic), and energy (vertically integrated state firms). The Stigler frame explains why Kenya's KPLC, Safaricom, and the major bank cartel persist despite competition-policy frameworks — the regulators are smaller and weaker than the regulated.
How to use it
Read regulation through the lens of who wins and who loses. 'Consumer protection' that raises entry barriers often serves incumbents. Stigler's reflex: cui bono?
