EMU Enlargement, Stabilization Cost and Automatic Stabilizers

subject

description

We use a new approach to assess long-term fiscal developments. By analyzing the time-varying behaviour of the two components of government spendingandrevenue–responsivenessandpersistence–, a feature not captured by automatic stabilisers, we are able to infer about the sources of fiscal deterioration (improvement). Drawing on quarterly data, we estimate recursively these components within a system of government revenue and spending equations using a Three-Stage Least Squaremethod for eight EuropeanUnion countries plus the US. The results suggest that significant changes in the fiscal stance (including those related to the current crisis) are reflected in the estimates of persistence and responsiveness.
