What explains citizen preferences for redistribution across regions within a country? Around the world, countries vary greatly in how much central governments tax wealthier regions to redistribute to poorer ones in order to reduce inequality across regions. In many federations or multi-tiered polities, these issues are salient, electorally contested, and at times polarizing; they have sometimes led to demands for or attempts at secession from disaffected regions. Such issues have been politicized in wealthy countries including Belgium, Canada, Italy, Spain, the United Kingdom, as well as in poorer or middle-income states including Argentina, Brazil, China, India, Mexico, and Russia. Yet the recent growth in research on the causes and consequences of different federal arrangements and fiscal federalism have not studied in depth the roots of individual preferences over basic issues related to federal institutions and fiscal federalism. This omission is surprising given the high salience of this package of issues in such countries.
