Elinor Ostrom and Oliver Williamson

Citation: For her analysis of economic governance, especially the commons (Ostrom) and for his analysis of economic governance, especially the boundaries of the firm (Williamson).

The key idea

Ostrom: common-pool resources are not doomed to the 'tragedy of the commons'; communities often govern them sustainably through nested institutions. Williamson: the make-or-buy decision turns on transaction costs, asset specificity, and the threat of hold-up.

The explanation

Ostrom's Governing the Commons (1990) documented dozens of successful community-based commons management — fisheries, forests, irrigation — and identified design principles. Williamson's transaction-cost economics (1985) explained why firms vertically integrate when transactions involve specific assets and uncertainty.

Why Africa should care

Ostrom is enormous for Africa. Pastoralist range management in Kenya, community forests in Tanzania, fisheries co-management in Lake Victoria — all are governed by Ostrom-style institutions that Western law often misclassifies as 'unowned'. Williamson's framework explains why African agribusiness vertically integrates (Mumias Sugar, Kakuzi, Magadi Soda) — to manage asset-specific transaction risk.

How to use it

When evaluating natural-resource governance, don't default to privatisation or state ownership. Ostrom's design principles often suggest community arrangements outperform both. When evaluating make-or-buy, identify the asset specificity — if low, market; if high, integrate.
