This paper employs systems-based cointegration techniques developed by Joha
nsen (1998, Journal of Economic Dynamics and Control 12, 231-254; 1995, Lik
elihood-based Inference in Cointegrated Vector Autoregressive Models, Oxfor
d University Press) to determine which European Union countries would form
a successful Economic and Monetary Union (EMU), based on long-run behavior
of the nominal convergence criteria laid down in the Maastricht treaty. The
original 12 European Union countries are analyzed together. Nominal exchan
ge rates, real exchange rates, long-term interest rates, and government bud
get deficits are each analyzed for co-movements among the 12 countries and
various subgroups of them. The results suggest that not all of the 12 origi
nal countries of the European Union can form a successful EMU over time, un
less several countries make significant adjustments. (C) 2000 Elsevier Scie
