概要	Political budget cycle analysis is an econometric framework for detecting whether incumbent governments manipulate fiscal policy — deficits, public spending, or taxes — in the run-up to elections to signal competence and win votes. Kenneth Rogoff's 1990 equilibrium model gave the idea rational micro-foundations: even forward-looking voters can be temporarily fooled when competence is imperfectly observed, so able incumbents distort the fiscal mix before an election to separate themselves from less able rivals. Empirically the cycle is identified by an election-timing indicator in a fixed-effects panel regression of fiscal outcomes, and Brender and Drazen's 2005 study showed the effect is concentrated in new, inexperienced democracies rather than established ones.	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.
