Resumen de Public Spending and the Paradox of Supermajority Rule

Dongwon Lee, Thomas E. Borcherding, Youngho Kang

• This article examines the paradox that a supermajority rule in a legislature promotes excessive government spending. We propose a simple conjecture: If rent-seeking coalitions dominate legislative politics and if individual legislators' demands for rent-seeking activities are price-inelastic, a change of legislative rules from simple majority to a supermajority will lead to greater public spending, other things equal. Using data from U.S. state legislatures, 1970 to 2007, we find that the adoption of a supermajority rule has a robust, positive impact on various types of tax revenues and government expenditures.
