Does Education Really Help? [PDF ebook] 
Skill, Work, and Inequality

This book challenges the conventional wisdom that greater schooling and skill improvement leads to higher wages, that income inequality falls with wider access to schooling, and that the Information Technology revolution will re-ignite worker pay. Indeed, the econometric results provide no evidence that the growth of skills or educational attainment has any statistically significant relation to earnings growth or that greater equality in schooling has led to a decline in income inequality. Results also indicate that computer investment is negatively related to earnings gains and positively associated with changes in both income inequality and the dispersion of worker skills. The findings reports here have direct relevance to ongoing policy debates on educational reform in the U.S.
