Economic voting in multi-tiered polities

This paper assesses whether economic voting plays any role in a parliamentary, decentralized polity. Decentralization is argued to blur lines of responsibility and confuse voters about whom to blame for poor economic performance at the national and regional levels. National and Regional Economic Voting (NEV and REV, respectively) are tested in Catalonia (Spain). The initial empirical test suggests that only NEV takes place in this region. Four hypotheses are considered to explain REV’s absence: blame-shifting, blinding nationalism, coalition government, and misinformation regarding Policy Responsibility Distribution across tiers of government. Using reasonable counterfactuals and Bayesian techniques, the first three hypotheses are dismissed, whereas the last is confirmed. The results emphasize the informational requirements behind the economic voting theory.

► Regional and national economic voting are tested in a parliamentary system. ► Regional and nation economic voting require different informational standards. ► Only sophisticated voters vote economically at regional level. ► All voters vote economically at national level. ► Bayesian techniques are applied to avoid risky assumptions.
