This article assesses convergence in output per head across regions in
the European Community, for the period 1975-90. We use three alternat
ive methodologies to measure convergence, which yield consistent resul
ts. We observe that there are strong differences in the pattern of con
vergence across sub-periods and across subsets of regions. If the sout
h of Europe seems to catch up in the early 1980s, it stagnates, at bes
t, in the second part of the eighties. At the opposite end, the region
s in the north of Europe tend to stagnate or diverge in the first part
of the eighties but converge strongly thereafter. This pattern is con
sistent with the view that northern European countries have adjusted b
etter to the main change in policy regime which occurred in the mid-19
80s, namely the implementation of the internal market programme and th
e entry of the Iberian peninsula in the Community in 1985. This eviden
ce also lends support to the view that trade liberalization can exacer
bate disparities. Finally, our evidence indicates that the distinction
between the north and the south of the EC is likely to be more releva
nt in the analysis of growth patterns than the distinction between the
centre and the periphery. Preliminary evidence on migration indicates
that the population of the southern regions responds much more slowly
to wage and unemployment differences. This may explain partly why sou
thern regions have not converged after 1985.
