Fiscal Rules and Discretion in a World Economy

Halac, Marina, and Pierre Yared. 2018. "Fiscal Rules and Discretion in a World Economy." American Economic Review, 108 (8): 2305-34.

Governments are present-biased toward spending. Fiscal rules are deficit limits that trade off commitment to not overspend and flexibility to react to shocks. We compare coordinated rules, chosen jointly by a group of countries, to uncoordinated rules. If governments' present bias is small, coordinated rules are tighter than uncoordinated rules: individual countries do not internalize the redistributive effect of interest rates. However, if the bias is large, coordinated rules are slacker: countries do not internalize the disciplining effect of interest rates. Surplus limits enhance welfare, and increased savings by some countries or outside economies can hurt the rest.
