¹⁶ Monetary policy has no unique category in this scheme. In the scheme the author develops below it appears under EI only as a service. The more significant aspects of monetary policy appear under P₂ below.

¹⁷ Another possibility which arises from the use of this measure is that it can be used in relation to a regression chart constructed by K. Deutsch, L. Bliss, and A. Eckstein to provide an estimate of the distance to be traveled before reaching the ceiling of intraregional trade if a group were in fact a single state of comparable size. Deutsch estimates a ceiling of 60–65 percent for the EEC, indicating that it is roughly two-thirds of the way to the level of trade integration that might be associated with national status.

⁴⁰ This approach to policy integration focuses on process rather than outcome. At the higher degrees of extent the difference is not important, but in some cases of low degrees of extent (states acting individually), there may be a surprisingly high degree of similarity in a policy outcome. However, similarity does not necessarily mean interdependence. It might reflect a mutual self-awareness or regional “demonstration effect” in Scandinavia but merely a residue of previous colonial rule in East Africa. To the degree that it is a result of conscious coordination it is picked up by the index of extent. It might be better to handle non-deliberate similarity in policy outcome by including it as a measure of “region” than to include it in an index of integration conceived of as a process.

Hostile incidents equal hostile reports in major press; hostile statements by important leaders; press reports of tense relations; diplomatic protest and break in relations; invasion by exiles from neighbors; troop movements to border; direct clash of troops.

⁴⁹ For instance, it would be hard to scale the effects of recent press emphasis on the French doctrine of “defense against all directions.”
