Partisan Differences in Economic Outcomes and Corresponding Voting Behavior: Evidence from the U.S.

The present empirical work examines the differences ineconomic outcomes delivered by partisan governments, and theway in which voters take this into account. Autoregressivemodels of output growth, unemployment and inflation, augmentedwith political variables; and probit binary choice models ofvoting decisions, incorporating expectations about inflationand unemployment, are estimated for U.S. post-war data. Theanalysis confirms that partisan differences in economic outcomes are actually observed in the data. U.S. unemployment rate exhibits adistinct partisan cycle, behavior of output growth andinflation rate partly supports the partisan differenceshypothesis. Thus suggesting that each party can be``instrumental'' in solving particular economic problems. Inline with this logic, U.S. voters seem to believe in theasymmetric abilities of parties to fight inflation andunemployment. Most interesting empirical findings includeevidence that U.S. citizens tend to vote for the left party(Democrats) when high unemployment is expected, and for theright party (Republicans) when high inflation is expected.This relation is especially robust for Presidential elections.There is also evidence pointing to the presence of electoralinertia and absence of ``midterm'' electoral cycle in the U.S.
