The use of modern microeconomics in policy is illustrated by the markets for spectrum, electricity, greenhouse-gas reductions, defense procurement, and Treasury bills. Further examples are antitrust divestiture rules, market-based redistribution, fishery conservation, and privatization. The limits of the use of theory are also discussed, by reference to Chinas economy-wide reforms. Lessons on the policy use of theory are drawn.
