The key idea
Mechanism design: given an objective, design a game so that rational players choose actions that achieve it. The revelation principle: focus on direct mechanisms where players truthfully reveal their types.
The explanation
Hurwicz introduced incentive compatibility (1960s). Myerson's optimal-auction theorem (1981) characterised the revenue-maximising auction. Maskin's monotonicity condition identified which social-choice rules can be implemented in Nash equilibrium. Together they reversed game theory: from analysing given games to designing games that yield desired outcomes.
Why Africa should care
Mechanism design is the framework behind every African spectrum auction (Kenya 2008, Nigeria multiple rounds, South Africa 2022), every agricultural subsidy delivery mechanism (M-Pesa-based Cash Transfer to Bursaries, NHIF capitation), and every African public-procurement reform. Designing tax-compliance mechanisms (eTIMS in Kenya) is mechanism design.
How to use it
Whenever you need to elicit private information from many agents (true ability-to-pay, true valuation, true risk type), think mechanism design. Incentive compatibility is the discipline; revelation principle is the simplifying tool.

Heckman: selection bias has structure and can be corrected. McFadden: the multinomial logit and conditional logit make discrete-choice data (yes/no, which-brand) econometrically tractable.
- 2001George Akerlof, Michael Spence, and Joseph Stiglitz
Akerlof: in markets with information asymmetry, bad goods drive out good ones (the lemons problem). Spence: education can signal innate ability even if it produces nothing. Stiglitz: insurance markets unravel under asymmetric information; screening contracts emerge in equilibrium.

Kahneman: prospect theory — people are loss-averse, weight probabilities non-linearly, frame matters. Smith: experimental markets reach competitive equilibrium remarkably fast even with few traders.
- 2003Robert Engle and Clive Granger
Engle: ARCH/GARCH models — volatility clusters, time-varies, can be forecast. Granger: cointegration — non-stationary series can share a stationary long-run relationship; pairs trading and error-correction modelling follow.

Time inconsistency: optimal policy announced today becomes sub-optimal tomorrow once private agents have reacted. Real Business Cycle theory: business cycles can arise purely from technology shocks under flexible prices.
