What is meant by 'X-inefficiency' in microeconomics?

💡 Solution & Explanation

X-inefficiency describes the failure of business enterprises to attain maximum potential output from a given combination of inputs due to managerial slack, bureaucracy, or weak market competition. This concept, formulated by economist Harvey Leibenstein, demonstrates that monopolies often tolerate higher internal costs because competitive pressures are absent. Alternative economic concepts like deadweight loss deal specifically with market distortions caused by taxes or price controls rather than internal firm management. Economics syllabi use this theory to explain deviations from standard profit-maximization models.
