“…While it would be difficult to assess ex post exactly how much the SMP affected economic growth in the EC from the late 1980s to the mid-1990s (when the vast majority of the directives were in place), it is clear that economic growth was not strong in the EC over this period, at least relative to the United States. Hoffman (2000), for example, in an ex post study finds that GDP was only 0.84 per cent higher due to the (not entirely complete) implementation of SMP directives. If, indeed, the growth effects were overestimated by Cecchini (1988) and others, did the SMP still have the expected positive effects on non-partners?…”
