An evaluation of Soviet claims that the Communist countries, by virtue of their central planning and rapid growth, represent much more attractive markets for primary-product exports from underdeveloped countries than do the allegedly stagnant and unstable economies of the West. It is found that the Soviet market not only falls short of such perfections, but is, compared to Western markets, neither large nor particularly stable. Soviet claims of rapid growth in primary-product imports are, however, fully confirmed by the data. This Paper is a summary of RM-3341-PR. It extends the period covered by the Memorandum by including data for 1961 in the calculations.
