Foundations of Economics, Anderson University DBA Summer 2001 Analysis of Educational Attainment’s Effect on Corporate Profitability KARL R. KNAPP Anderson University – Anderson IN ABSTRACT This paper analyzes the statistical correlation between the educational attainment of the U.S. population and profitability of U.S. corporations. The basic hypothesis being tested is that the increase in percentage of college educated Americans has had a direct effect on profitability of American corporations. Hypothesis A better-educated workforce directly benefits corporations through corresponding increases in profitability. This is the basic premise being explored. While the missions of corporations are often stated in non-materialistic terms, the reality of the situation is that corporations must generate normal profits to stay in business. Corporations strive in the marketplace for opportunities to exceed normal profit and experience real economic profit. For this reason corporate profitability can be used to illustrate the overall performance of corporations. This profit goal is the dependent variable in this study. Profit can be derived in many ways. The education of corporate employees is usually a key ingredient to success. While there are certainly other societal motivations for education, corporations are major stakeholders in American education. 2001by Karl R. Knapp Over the past one hundred years universities have become increasingly utilitarian in their curriculum. University education has moved from being based on a classical (liberal) foundation dedicated to the creation of an educated clergy, to a curriculum based on science dedicated more to serving utilitarian business needs. This transition in the curriculum should have affected American business. In addition to changes in college curriculum, there has been an increasing trend in the percent of the U.S. population receiving a college education. This should have also affected American business. Initial Regression Analysis In order to analyze the effect of education on corporate profitability two regression analyses were completed. The first regression analysis explored the effect of the U.S. population’s educational attainment to corporate profitability. In this first analysis the following variables were used: Page 1 of 4 0812/2001 Foundations of Economics, Anderson University DBA Summer 2001 Independent Variable: Corporate Profits per Labor Force Member Dependent Variable: % of Population Completing 4 or More Years of College The independent variable was calculated on a per-labor-force-member basis to account for the growth in corporate profits attributable to the growth of the domestic market (civilian labor force). Results of this initial regression analysis showed a strong correlation between the dependent variable and the independent variable. Adjusted R2 T-Stat of Independent Variable T-Stat of the Intercept 84.7 14.7 12.9 The final regression analysis built upon the initial regression by adjusting for the effect of inflation on corporate profitability. The consumer price index (CPI) was used to adjust corporate profits to a ‘real’ basis. In the final regression analysis, the following variables were used: Independent Variable: InflationAdjusted Corporate Profits per Labor Force Member Dependent Variable: % of Population Completing 4 or More Years of College Results of this final regression analysis showed virtually no correlation between the dependent variable and the independent variable.

Knapp $4,500 $4,000 Real Corporate Profits per Labor Force Member In this initial regression the hypothesis proved to be significant by explaining 84.7% of the variation in the dependent variable. The T-Stat of the dependent variable was certainly significant at 14.7 (above 2.0). The main weakness in this initial regression was that the T-Stat of the Intercept was also strongly significant at 12.9. This most $3,500 y = -4.6697x + 3440.3 2 R = 0.002 $3,000 $2,500 $2,000 $1,500 $1,000 $500 $0 0.0 5.0 10.0 15.0 20.0 25.0 30.0 % of Population with 4 Years of College or More The hypothesis proved to be insignificant. When adjusting for inflation, Page 2 of 4 0812/2001 Foundations of Economics, Anderson University DBA Summer 2001 the increased educational attainment of the U.S. population shows almost no effect on real corporate profitability per labor force member. Conclusion In conclusion the educational attainment of the U.S. population be used to explain changes in corporate profitability. The initial regression analysis performed showed that several other variables missing from the equation explain the changes in corporate profitability. While educational attainment may indeed be significant in the context of a more comprehensive formula, when taken alone it cannot be said to explain the variances in corporate profitability. 2001by Karl R.
