[Income, labor, and population reproduction].

"The interrelations between...income, labour stimuli and population reproduction in Bulgaria are analyzed. The change of consumer price rates and purchasing power are considered and their impact on...living conditions is estimated. The economic relation 'work--consumption--motivation' is studied in regard to its influence on the demographic processes. The conclusion is that the fall of the average per capita income in the country to the social minimum level creates acute social problems." The article concerns the period 1990-1991.
