The International Comparison of Value Added, Productivity and Purchasing Power Parities in Agriculture

This study is part of the ICOP (International Comparison of Output and Productivity) project of the University of Groningen. It presents international comparisons of levels of value added, productivity and purchasing power parities (PPPs) in agriculture for 13 countries for 1975. An early version of this paper was issued in 1984 (Research Memorandum 162 of the Institute of Economic Research, Groningen). In 1985 a slightly revised version was given limited circulation. The present paper contains further revisions, makes an assessment of other studies in this field, confronts our results with those of Prasada Rao (1986 and 1992) and contains suggestions for further research.
