The implications of European fiscal harmonization for the French econo
my are examined using a general equilibrium model. The model extends t
he overlapping generations, simulation model developed by Auerbach and
Kotlikoff in three ways: a well-developed external sector is included
; households face constraints in their borrowing; and the population c
omprises "rich" and "poor" households with different labor productivit
ies. The harmonization policy that involves cuts in VAT and savings ta
xes leads to welfare losses for both rich and poor approximately equiv
alent to 1 percent of GDP.
