Citation: For their contributions to the theory of optimum allocation of resources.
The key idea
Linear programming. An optimal allocation problem with linear constraints and a linear objective has a dual: shadow prices on resources that emerge from the solution.
The explanation
Kantorovich invented linear programming in 1939 to plan plywood production in the USSR. Koopmans developed activity analysis — modelling production as a choice of activities subject to resource constraints — and showed the duality between the primal optimisation and the resource-shadow-price problem. Together they laid the algorithmic foundation of operations research.
Why Africa should care
Every yield-curve fitting, optimal transport-cost solution, and Kenyan agricultural-allocation model uses LP. The shadow-price interpretation of dual variables is exactly the framework an East African Community trade negotiator should use when arguing about effective tariff equivalents.
How to use it
Whenever you face a resource-allocation problem (budget across ministries, port capacity across imports, fertilizer across counties), formulate the LP. The shadow prices that emerge are the willingness-to-pay for relaxing each constraint — a richer guide than back-of-envelope intuition.

Economics is a measurable science. Build dynamic equations of the economy, estimate them with data, use them to forecast and design policy.

Economic theory has the structure of physics: optimisation under constraints, with comparative statics and dynamic stability following from the same maximisation principles.

Growth is structural transformation, not a single line on a chart. Inequality follows an inverted U as economies industrialise — the Kuznets curve.

When can the totality of competitive markets simultaneously clear, and when is that outcome socially efficient? Arrow-Debreu (1954) proved existence; the First Welfare Theorem proved efficiency — under restrictive assumptions.

An economy is a matrix. Each sector produces output by buying inputs from other sectors. Once you know the matrix of inter-industry flows, you can compute the total impact of any final-demand change.
