We build a general equilibrium macro model of a transitional economy t
o reflect four stylized facts. Among these are that central planning h
as left a legacy of highly concentrated industry and a residue of pric
e controls and rationing. An 'almost' Classical Dichotomy obtains in t
he model: monetary expansion leaves output and employment unchanged (d
espite the existence of unemployment), though leisure time declines. H
owever, the economy displays a high degree of complementarity between
the state-controlled and private sectors, giving rise to Keynesian mul
tiplier effects. We also analyse the effects of price-liberalization a
nd privatization on the properties of the economy.
