Summary of "MEXICO: TWO DECADES OF THE EVOLUTION OF EDUCATION AND INEQUALITY"

Core Content

This paper explores the relationship between education and inequality in Mexico over the past two decades, focusing on earnings inequality and how it has evolved in tandem with changes in the distribution of educational attainment.

Main Findings

• Inequality Trends: Mexico experienced a significant rise in inequality during the 1980s and mid-1990s, but saw an improvement in earnings inequality after 1996. Despite some recent progress, national and urban income inequality remains high compared to other countries.

• Education's Role: Education is identified as the most significant factor in explaining changes in earnings distribution. It has the highest gross contribution to earnings inequality.

• Synchronization of Changes: Changes in the distribution of education and in the relative earnings among educational groups have always been in phase with changes in the overall earnings distribution. When the income profile effect related to education became steeper and inequality in education increased, earnings inequality also worsened (e.g., 1988–1996 period).

• Relative Earnings as a Leading Force: Changes in the relative earnings among educational groups are the leading force behind changes in inequality.

Key Data Points

• Gini Coefficient:

  • In 2000, Mexico's Gini coefficient was 54.6, higher than the Latin American average but lower than Brazil, Chile, and Colombia.
  • The Gini coefficient for urban areas was 0.484 in 2000, decreasing slightly to 0.462 in 2002 before increasing to 0.476 in 2004.
  • For rural areas, the Gini coefficient was 0.532 in 2000, decreasing to 0.496 in 2002, and further to 0.468 in 2004.
  • The total Gini coefficient for Mexico was 0.536 in 2000, decreasing to 0.508 in 2002 and 0.503 in 2004.

• Income Share Ratios:

  • The ratio of the income share of the top 10% to the bottom 20% (R10/20) increased from 4.48 in 1988 to 6.74 in 1996, then declined to 4.81 in 2002.
  • The Theil T index showed a slight decline from 0.327 in 1988 to 0.302 in 2002, with a peak of 0.474 in 1996.

• Educational Attainment:

  • The average years of schooling in Mexico increased from 2.76 in 1960 to 6.72 in 1990, representing a rapid acceleration during the 1980s.
  • The education gap between Mexico and the rest of the world was significantly reduced, particularly in the 1980s, due to increased coverage and efficiency in education.

• Distribution by Gender:

  • Women showed greater improvements in educational attainment than men, especially at the top of the distribution.
  • In 2002, the cumulative distribution of education for women was higher than that for men, indicating a narrowing of the gender gap in education.

• Distribution by Economic Sector:

  • The financial sector employed a more highly skilled labor force, while the primary and "Other services" sectors used more low-skilled labor.
  • Commerce showed a heterogeneous distribution, and the education levels of workers varied across sectors.

• Distribution by Age Group:

  • Educational attainment improved significantly for younger age groups compared to older ones.
  • The percentage of individuals with incomplete primary schooling decreased over time, while those with higher education levels increased.
  • There was a growing negative correlation between education and age, indicating that educational improvements have been more pronounced among younger generations.

Methodology and Framework

• The paper uses the National Urban Employment Survey (ENEU) to analyze earnings inequality and educational attainment.
• It establishes an analytical framework to examine the interaction between education and the labor market.
• The study employs ordinary least squares and quantile regressions to assess the rates of return to education.

Conclusion

• The increase in earnings inequality in Mexico is primarily attributed to skill-biased technological change rather than trade liberalization or institutional changes.
• Educational policies have played a crucial role in shaping the labor market and reducing inequality, particularly in terms of improving access to education and its efficiency.
• The paper highlights the need to understand how educational attainment and its distribution interact with labor market dynamics to address inequality effectively.
