สรุป	Economic voting analysis is the formal study of how voters reward or punish incumbents according to economic performance. In the reward-punishment (retrospective) model pioneered by Gerald Kramer in 1971, support for the governing party is a function of recent economic outcomes — growth, unemployment, and inflation — so that good times re-elect incumbents and bad times turn them out. Michael Lewis-Beck and Mary Stegmaier's 2000 review consolidated the field, establishing that economic voting is predominantly sociotropic (based on the national economy rather than personal finances) and that its strength depends on the clarity of responsibility: how easily voters can attribute outcomes to the incumbent.	The probabilistic voting model is a formal theory of electoral competition in which each voter's choice between two parties is treated as stochastic rather than deterministic, governed by a smooth probability that depends on the policy utilities the parties offer plus idiosyncratic and partisan preference shocks. Developed by Assar Lindbeck and Jörgen Weibull in 1987 and given its general treatment by Peter Coughlin in 1992, the model replaces the knife-edge switching of the median voter framework with continuous vote-share functions. Two office-seeking parties maximize expected vote share, and the resulting equilibrium maximizes a density-weighted social welfare function in which the most responsive — the swing — voters carry the greatest weight. Crucially, the model delivers a determinate, interior equilibrium even in multidimensional policy spaces where a Condorcet winner generically fails to exist.
