The purpose of this paper is to investigate to what extent modifications of
tax systems between 1985 and 1992 within major parts of the European Union
contributed to changes in the labour market. The principal countries under
investigation are Germany, Italy, France and the United Kingdom, and the m
ethod of investigation is the numerical simulation of a multi-country gener
al equilibrium model. Changes in VAT rates and in the personal income tax s
chedule are investigated. We conclude that a non-trivial part of the labour
market changes may be due to reactions of the market to changes in these t
ax rates.
