Lindon J. Robison & Marcelo Siles
This research report examines if changes in income inequality and changes in income are associated with social capital or the strength of relationships. The methodological approach taken by Robison and Siles is quantitative. They specifically test the relationship between social capital indicator variables and changes in the distribution of household income. For this study the authors rely on Census data from the 1980s and 1990s. The authors found that the largest increase in income inequality was among White households and the lowest increase was among Asian households. In conclusion, Robison and Siles find that changes in social capital has a significant effect on the disparity and level of household income.
