August 2015Fiscal Rules and Discretion in a World Economy
with Pierre Yared: w21492
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 centralized rules — chosen jointly by all countries — to decentralized rules. If governments' present bias is small, centralized rules are tighter than decentralized rules: individual countries do not internalize the redistributive effect of interest rates. However, if the bias is large, centralized rules are slacker: countries do not internalize the disciplining effect of interest rates. Surplus limits and money burning enhance welfare, and inefficiencies arise if some countries adopt stricter rules than imposed centrally.
November 2012Fiscal Rules and Discretion under Persistent Shocks
with Pierre Yared: w18545
This paper studies the optimal level of discretion in policymaking. We consider a fiscal policy model where the government has time-inconsistent preferences with a present-bias towards public spending. The government chooses a fiscal rule to trade off its desire to commit to not overspend against its desire to have flexibility to react to privately observed shocks to the value of spending. We analyze the optimal fiscal rule when the shocks are persistent. Unlike under i.i.d. shocks, we show that the ex-ante optimal rule is not sequentially optimal, as it provides dynamic incentives. The ex-ante optimal rule exhibits history dependence, with high shocks leading to an erosion of future fiscal discipline compared to low shocks, which lead to the reinstatement of discipline. The implied policy...
