If memory serves, the apparent inability to control wage growth did the central planning Eastern European style in. The planners had an "iron" formula that the wage increases should be lower than productivity growth, but they were unable to adhere to this formula for the following reasons:
1. Annual productivity growth rates were declining throughout the 1960s and 1970s (see Chavance, _The Transformation of the Communist Systems_, Westview Press, 1994).
2. The wage control mechanisms instituted under the central planning system did not work as planned, chiefly due to the following factors:
- regional shortages of skilled labor;
- grey economy (at both enterprise level i.e. factory managers subverting wage schedules to attract labor and individual level i.e. employees stealing from their employers on a massive scale); - social protest demanding higher wages and standards of living - failure of administrative price control to compensate for "inflationary" wage increases (i.e. those not warranted by productivity gains); this failure was in a substantial part due to the social protest in response to price increases.
It seems that the US brand of capitalism does much better in this respect - as all productivity gains are appropriate by the employers or are achieved by the reduction of labor input.
