1 Educational Attainment and Income Inequality in Southeast Missouri Kang H. Park Professor of Economics Southeast Missouri State University

2 Introduction  Human capital theory: –Educational spending is an investment because it increases worker productivity. –Human capital theory is used to explain income differentials.  This study examines the effects of educational variables on income and income inequality in Southeast Missouri, using the 2000 US census data covering 34 Southeast Missouri counties.  Gini index from B. Domazlicky’s 2005 article.

11 Summary  A higher levels of income and education have an equalizing effect on income distribution  The dispersion of schooling has a disequalizing effect on income distribution.  Both LnCapita and EDSD (or EDCV) are statistically significant in explaining the poverty rate.  only EDSD(or EDCV) can explain the Gini index well.
