The book explains how different political and economic circumstances account for the variation in the economic vote. Based on the analysis of 165 public opinion surveys from 19 countries, the authors demonstrate that their explanations are empirically sound.

This book proposes a selection model for explaining cross-national variation in economic voting: Rational voters condition the economic vote on whether incumbents are responsible for economic outcomes, because this is the optimal way to identify and elect competent economic managers under conditions of uncertainty. This model explores how political and economic institutions alter the quality of the signal that the previous economy provides about the competence of candidates. The rational economic voter is also attentive to strategic cues regarding the responsibility of parties for economic outcomes and their electoral competitiveness. Theoretical propositions are derived, linking variation in economic and political institutions to variability in economic voting. The authors demonstrate that there is economic voting, and that it varies significantly across political contexts. The data consist of 165 election studies conducted in 19 different countries over a 20-year time period.
