the system ai if    it ware    a closed system.    In other words,

according to    such    modela,    we could have had    exactly the same

performance* if our oountrles had contlnued to be only moderately dependant upon external trade and relatlonahips, as it used to be untll the Slxtles..

The second lmportant common feature is the common focusing of attentlon    upon    the causes of inflation.    Unemp1oyment, in

all aodel8,    is something    which happens to    exlst only In so

far as something wrong •• happens with regard to price eąuiłibrium. For the neo-monetarists the disturbing factor is given by an excess of money, for which the State is the direct responslbłe; for the neo-Keynesians the 'wrong variable' is given by the level of nominał wages (or of the nominał wages dynamice), which is too high. But in both cases, once the price equillbrlum conditions are broken, unemployment will resułt as a consequence of it.

The third common feature is given by the common a I cr oeconom i c spec 1 f 1 ca 11 nn of all t.heae modełs, which pivot on the hypot.heala of d 1 m 1 n 1 ah 1 ng ' ret.urna t.o scalę. Thla point. 1a c r u dal;    ao oruclal    t.hat., ahould one wlt.hdraw the
