This paper critically reviews the literature which explains why and under which circumstances governments accumulate more debt than it would be consistent with optimal fiscal policy. We also discuss numerical rules or institutional designs which might lead to a moderation of these distortions

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...

This paper develops a model of optimal government debt maturity in which the government cannot issue state-contingent bonds and cannot commit to fiscal policy. If the government can perfectly commit, it fully insulates the economy against government spending shocks by purchasing short-term...

This paper offers three results. First, in line with the previous literature, we confirm that fiscal adjustments based mostly on the spending side are less likely to be reversed. Second, spending based fiscal adjustments have caused smaller recessions than tax based fiscal adjustments. Finally,...

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...

We study a fiscal policy model in which the government is present-biased towards public spending. Society chooses a fiscal rule to trade off the benefit of committing the government to not overspend against the benefit of granting it flexibility to react to privately observed shocks to the value...

According to the Lucas-Stokey result, a government can structure its debt maturity to guarantee commitment to optimal fiscal policy by future governments. In this paper, we overturn this conclusion, showing that it does not generally hold in the same model and under the same definition of...

This paper summarizes the results of a large recent literature on multi year fiscal plans for deficit reduction (austerity). The key results are that deficit reduction policies based upon spending cuts are much less costly in terms of short run output losses than tax based adjustments. On...
