Over the last few years, a comprehensive insight into the effects of the single market program (hereafter entitled EC-1992) has become more difficult because of the parallel steps of extending integration toward the member countries of the European Free Trade Area (EFTA) as well as toward Central and East European countries (through so-called Europe agreements). Both deepening integration through EC-1992 and extending integration involve a number of measures that since the publication of the Emerson Report (1988) have been principally discussed under the dimension of European Community (EC) internal adjustment and challenges rather than under the external dimension.
