Scenario: the Following Excerpts Describe Some Practices of Determining Wages

Scenario: The following excerpts describe some practices of determining wages in the Soviet economy. "Centrally-fixed weightings based on an accurate comparison of the cost of living in different regions is one of the advantages of the current [1980s] method of wage regulation. In practice, however, even here we do not find what might have been expected. … government departments enjoying a high status fix higher weightings for their workers than the local average. … As a result, workers earn different rates for the same job. … All this indicates that the advantages of regulating wages centrally for the whole country are often illusory because in principle it cannot be done on the basis of overall productivity. … In the face of life's complexity, wage regulation is not feasible and actual wage trends become semi-random."
