Efficiency of Investment in a Socialist Economy sums up the work done by the Economic Research Division of the Planning Commission at the Council of Ministers of the People's Republic of Poland on the theory of studies on the efficiency of investment and its applications. This work was to a great extent connected with the preparation of the new General Instruction on Methods of Studies of the Economic Efficiency of Investment published by the Planning Commission in 1962. The book is organized into two parts. Part I on research methods covers methods for economically assessing of the efficiency of investments involving the construction of new plants; for the economic assessment of supplementary investments in already functioning plants; and for the analysis of smaller investments. Part II presents several examples including calculation of the efficiency of investment for a mine producing boiler coal; the efficiency of replacement of old thermal power stations; and the efficiency of production of natural gas and oil. This book may be of interest to persons dealing with studies on efficiency of investment by virtue of their profession.
