ABSTRACT
Differences exist among the countries in point of development. Correspondingly, there exist structural reasons for heterogeneity in their public enterprise experience. The average annual growth rate which is the result of interaction of all development forces, reflects the weight of handicaps that a country experienced during the recent two decades. Those in the lower classes were more vulnerable to difficulties in growth and, by implication, in the working of public enterprises than the others. The size of population has some impact on development in that the smaller the size the smaller the domestic markets and perhaps the smaller the labour available. Exceptions do exist, but the market limits can impose severe diseconomies in production structures. For all the low-income countries and most of the middle-income group the frequencies of A-B exceed those of E-D; and for almost all the middle-income group and the high-income group the E-D frequencies exceed the A-B frequencies, the more conspicuously the higher the income.
