In this paper we utilise the Rosse-Panzar statistic to assess competit
ive conditions in major EC banking markets between 1986 and 1989. Alth
ough EC banking legislation has established relatively free access to
member country banking systems in recent years, our results indicate n
o change in market conduct of banks between 1986 and 1989. The results
suggest that banks in Germany, the United Kingdom, France and Spain e
arned revenues as if under conditions of monopolistic competition in t
he period. In the case of Italy, they are consistent with banks having
earned revenues as if under monopoly or conjectural variations short-
run oligopoly conditions. We interpret the results as indicative of a
lack of integration in EC banking markets and they thus underline the
importance of the Second Banking Directive, the associated supervisory
arrangements, and the elimination of capital controls as to achieving
full integration,
