The Evolution of Returns to Cognitive Skills Across Countries: Evidence on Factor Price Equalization

The study analyzes the evolution of returns to cognitive skills in 23 developed countries, revealing a decrease in average earnings increase from 20.3% in 2012 to 16.7% in 2023 per standard deviation in numeracy skills. It highlights significant cross-country variation, with one-third of countries experiencing increased returns, suggesting convergence is a more critical factor than technological change.

Key developments
Phase 1
The study analyzes the evolution of returns to cognitive skills in 23 developed countries, revealing a decrease in average earnings increase from 20.3% in 2012 to 16.7% in 2023 per standard deviation in numeracy skills. It highlights significant cross-country variation, with one-third of countries experiencing increased returns, suggesting convergence is a more critical factor than technological change.
  • The study examines the evolution of returns to cognitive skills in 23 developed countries, noting a decrease in average earnings increase from 20.3% in 2012 to 16.7% in 2023 per standard deviation in numeracy skills
  • There is notable cross-country variation, with one-third of the countries experiencing increased returns to cognitive skills, indicating that convergence is a more significant factor than technological change
  • Measurement errors in labor market studies pose challenges, particularly the assumption that years of schooling are equivalent across countries, which may not accurately represent workers true skill levels
  • Utilizing psychometrically linked PIAAC surveys, the research underscores the need for improved skill measures beyond just years of education for consistent international comparisons of skill returns
  • Countries with higher labor-market flexibility and openness to trade, particularly in intangible assets, show faster convergence in returns to cognitive skills, supporting the theory of factor price equalization
Phase 2
The study examines the evolution of returns to cognitive skills in 23 developed countries, revealing a decline from 20.3% in 2012 to 16.7% in 2023. It highlights significant cross-country variation, with convergence being a key factor in this trend.
  • Returns to cognitive skills vary significantly across developed countries, with highly skilled individuals in the US earning more than those in Greece
  • From 2012 to 2023, there has been a notable convergence in skill returns, indicating a trend towards factor price equalization, driven by labor market openness and international trade, especially in intangibles
  • Countries with flexible labor markets and greater openness to trade experience faster convergence in returns to cognitive skills, highlighting the importance of these factors in labor market dynamics
  • The analysis indicates that migration does not significantly affect overall returns to skills, as individual skill assessments remain consistent regardless of the country of origin
Phase 3
The study analyzes the evolution of returns to cognitive skills in 23 developed countries, revealing a decline from 20.3% in 2012 to 16.7% in 2023. It highlights significant cross-country variation, with convergence being a key factor in this trend.
  • The analysis utilizes the OECDs Program for International Assessment of Adult Competencies (PIAAC), which surveys adult skills across various countries, providing a comprehensive dataset for examining returns to cognitive skills over time
  • Returns to cognitive skills, especially in numeracy and literacy, show significant variation across countries, with the U.S. demonstrating higher returns compared to nations like Greece
  • From 2012 to 2023, there has been a marked convergence in returns to cognitive skills, indicating a trend towards factor price equalization, driven by labor market flexibility and openness to international trade
  • While non-cognitive skills were assessed, their influence on earnings is minimal compared to cognitive skills, underscoring the latter as the main factor in wage disparities
  • The PIAAC survey methodology is recognized for its rigor, featuring extensive testing and a representative adult sample, which enhances the reliability of the results
Phase 4
The study analyzes the evolution of returns to cognitive skills in 23 developed countries, revealing a decline from 20.3% in 2012 to 16.7% in 2023. It highlights significant cross-country variation, with convergence being a key factor in this trend.
  • The analysis examines returns to cognitive skills, particularly numeracy and literacy, among full-time workers aged 35 to 54 in 23 developed countries, utilizing data from the PIAAC surveys of 2012 and 2023
  • Returns to numeracy skills have declined from 20.3% in 2012 to 16.7% in 2023, reflecting a convergence trend across countries, with one-third of nations experiencing increased returns despite the overall decrease
  • The study indicates that changes in skill returns are mainly driven by convergence rather than technological advancements, highlighting the influence of labor-market flexibility and trade openness
  • Normalization of skill measures is essential for accurate interpretation, as the method used can significantly affect the estimated returns to cognitive skills
  • Certain countries were excluded from the research due to data inconsistencies, underscoring the importance of reliable data in analyzing labor market outcomes
Phase 5
The study analyzes the evolution of returns to cognitive skills in 23 developed countries, revealing a decline from 20.3% in 2012 to 16.7% in 2023. It highlights significant cross-country variation, with convergence being a key factor in this trend.
  • The study employs a modified Mincer earnings function to estimate returns to cognitive skills, arguing that years of schooling alone do not adequately measure skill levels
  • Significant disparities in educational outcomes are evident, with U.S. students performing lower than peers in high-performing countries like Singapore, as shown by 15-year-olds test scores
  • Returns to numeracy skills have decreased from 20.3% in 2012 to 16.7% in 2023, indicating a convergence trend in cognitive skill returns across developed nations
  • The analysis highlights the importance of understanding human capitals relationship with income levels, particularly in high-income countries, while questioning the relevance of these measures for low-income nations
  • Identification issues in the data are noted, with suggestions to adjust years of schooling based on test results to better reflect human capital across different countries
Phase 6
The study examines the evolution of returns to cognitive skills in 23 developed countries, noting a decline from 20.3% in 2012 to 16.7% in 2023. It highlights significant cross-country variation, with convergence being a key factor in this trend.
  • Measuring human capital is complex, particularly when using the World Banks human capital index, which integrates education and health metrics
  • There is skepticism regarding the use of years of schooling as the sole indicator of human capital, as it may not accurately capture cognitive skills across different nations
  • The significance of experience in addition to education for understanding earnings, suggesting that neglecting experience could lead to inaccurate conclusions
  • While non-cognitive skills, such as social and psychological abilities, were analyzed, they were found to have minimal impact on the returns to cognitive skills, reinforcing the focus on cognitive abilities
  • Participants expressed interest in exploring diverse measures of human capital and their correlation with earnings, while recognizing the challenges in interpretation and consistency across countries
