Abstract
This paper examines whether changes in the degree of correlation of employment cycles across regions (of Belgium, France, Germany, Ireland, the Netherlands, and Spain) can be explained by changing patterns of specialisation. The empirical method adopted carries out pooled regressions for all possible region-pairs which relate moving correlations between the residuals of HP-filtered regional employment to their own past and an index of specialisation. As a test of robustness, the benchmark estimations which originally include dummies for common borders, German unification and relative differences between regional incomes are systematically tested down. The empirical results again highlight the problem of a common monetary policy for uncommon regions within the euro zone.

Relative income for a region-pair, calculated as the absolute value of the difference between the logarithms of real GDP of these two regions. Nominal regional GDP was deflated by the consumer price index of the country the respective regions belong to.
- DUM1::
-
dummy to describe the direct neighbourhood of two regions to each other (1 for common borders, 0 otherwise)
- DUM2::
-
dummy to describe the indirect neighbourhood of two regions to each other (1 for region-pairs separated by exactly one other region, 0 otherwise)
- DUMGER::
-
dummy for German unification coded as 1 for the period from 1990 on, otherwise 0.
