Multiple regression analysis of the occupational status of twins: a comparison of economic and behavioural genetics models
Article Abstract:
A study was conducted to compare the performance of the DeFries and Fulker model with the conventional fixed effects models in the study of economic well-being which is measured by the occupational rank of the individual's job. The study has been prompted by the existence of the methodological advantage in estimating the impact of schooling on economic well-being within the more general DeFries and Fulker model. Findings indicated that the estimation of the two models considered in the study was in the same order of magnitude as that estimated in studies that do not take account of genetic and shared environmental factors.

What do twins studies reveal about the economic returns to education? A comparison of Australian and U.S. findings
Article Abstract:
The economic returns to education were studied by analyzing previous studies on monozygotic twins and demographic data from the Australian Twin Register dating from 1988-1989. In a 1977 study, Jere Behrman et al discovered that World War II veteran twins had an average return to schooling of 8%, 2.7 percentage points were due to schooling and 2.1 percentage points were due to family environments. In the study on Australian twins, overall return to schooling were attributed evenly into education, ability and family environment.

Multiple regression analysis of the occupational status of twins: a comparison of economic and behavioural genetics models
Article Abstract:
The regression model proposed by J.C. DeFries and D.W. Fulker in 1985 is compared with the traditional fixed effects model in economic well-being studies. Economic well-being is measured by the occupational rank of a person's job. Both models were used to determine the effect of education in Australia based on genetic and shared environmental factors. Indirect methods are found to be effective in providing reliable controls for omitted genetic and shared environment variables.
