Tóm tắt	Rent-seeking analysis is the political-economy framework for measuring the social waste created when individuals and firms spend real resources competing for artificially created rents — the extra income generated by monopoly grants, tariffs, licenses, quotas, and other government-conferred privileges — rather than producing new wealth. Gordon Tullock's 1967 article showed that the conventional Harberger triangle drastically understates the cost of monopoly and protection, because the rectangle of monopoly profit, far from being a mere transfer, becomes a prize that competitors will expend resources to capture. Anne Krueger named the activity 'rent-seeking' in 1974 and demonstrated its macroeconomic scale in regulated developing economies. The analysis models the competition for a rent as a contest and asks how much of the prize is dissipated in the struggle to win it.	Public choice analysis is the application of the methods of economics — methodological individualism, rational self-interest, and equilibrium reasoning — to the study of political and collective decision-making. Pioneered by James M. Buchanan and Gordon Tullock in their 1962 book The Calculus of Consent and surveyed comprehensively in Dennis Mueller's Public Choice III, it treats voters, politicians, bureaucrats, and interest groups not as benevolent servants of the public interest but as utility-maximizing agents pursuing their own goals within political institutions. A central methodological move is the distinction between constitutional choice — the selection of the rules of the game behind a veil of uncertainty — and in-period choice within those rules. The framework's signature derivation is the optimal decision rule (the optimal majority), found by minimizing the sum of the external costs a rule imposes and the costs of reaching agreement under it.
