Tales of Fiscal Adjustment

Both consumption and investment rise. For this effect to produce an expansion, the tightening must be sizeable and occur after a period of stress when the budget is quickly deteriorating and public debt is building up. Another interpretation emphasizes the supply side. Typically, a fiscal consolidation based on tax increases is short-lived. To be long lasting, it must include cuts in public employment, transfers and government wages. lo be politically possible, such a policy must be supported by trade unions.

Based both on statistical evidence and on a detailed analysis often cares of major fiscal adjustment, this article provides cautious support to the supply-side view, without denying a more limited role for the demand-side channel.
