Sociological explanations of economic growth

Even if questions of how resources aredistributed within and between societies are our main concern, we must continue to grapple with the issue of the causes of economic growth because economic growth and level of development continue to be among the most important causes of inequality, poverty, unemployment, and the quality of life. This paper’s dependent variable is the economic growth rate of 55 less developed countries (LDCs) during two time periods—1970–78 and 1965–84. The causal model consists of control variables—level of development and domestic investment in 1965—and a variety of independent variables drawn from major sociological theories of economic growth published during the last three decades. Multiple regression analysis shows that, net of the effects of the two control variables, the variables that have the strongest effect on economic growth rates are: (1) direct foreign investment, which has a negative effect; (2) the proportion of the population in military service; and (3) the primary school enrollment ratio, both of which have positive effects of economic, growth. On the other hand, variables drawn from some theories receive no empirical suport. The mass media of communications, ethno-linguistic heterogeneity, democracy and human rights, income inequality, and state-centric theory’s key variable—state strength—all fail to show any significant impact on economic growth rates when the control variables and the significant independent variables are held constant. The theoretical implications of these findings are discussed.
