Budget referendums and government spending: evidence from Swiss cantons

In many Swiss cantons, new government programs must be approved by a referendum of citizens before money can be spent. Referendums seem like a natural way to address citizen-legislator agency problems, yet statistical evidence on how referendums affect spending decisions is almost nonexistent. We estimate regressions for Swiss cantons using panel data from 1980 to 1998 and find that mandatory referendums reduced government spending by 19% for the median canton after controlling for demographics and other determinants of spending.
