Responding to Voters or Responding to Markets? Political Parties and Public Opinion in an Era of Globalization

Conventional wisdom has it that political parties have incentives to respond to public opinion. It is also conventional wisdom that in open economies, policymakers must also “respond” to markets. Research on representation has provided ample evidence in support of the first claim. Research on the political economy of globalization has not, however, provided evidence for the second. This article examines the effects of globalization on how parties respond to voters. We argue that while elections motivate parties to respond to public sentiment, economic interdependence distracts political elites from their electorates and toward market actors, reducing party responsiveness to the mean voter. Evidence from a pair of distinct data sources spanning elections in twenty advanced capitalist democracies from the 1970s to 2010 shows that while parties have incentives to respond to left-right shifts in the mean voter position, they only do so when the national economy is sufficiently sheltered from the world economy. These findings have implications for party strategies, for representation, and for the broader effects of market integration.
