Our colleague Zuzana Havránková is the lead author and our colleague Prof. Tomáš Havránek is the co-author of the article Publication and Attenuation Biases in Measuring Skill Substitution, which was published this summer in The Review of Economics and Statisics (REStat).
REStat has been published since 1919 at Harvard University and is one of the most prestigious professional journals in the field of economics. Lubica Laslopova from Anglo-American University and Olesia Zeynalova, a PhD student at IES, also collaborated on the article.
A key parameter in the analysis of wage inequality is the elasticity of substitution between skilled and unskilled labor. We show that the empirical literature is consistent with both publication and attenuation bias in the estimated inverse elasticities. Publication bias, which exaggerates the mean reported inverse elasticity, dominates and results in corrected inverse elasticities closer to zero than the typically published estimates. The implied mean elasticity is 4, with a lower bound of 2. Elasticities are smaller for developing countries. To derive these results, we use nonlinear tests for publication bias and model averaging techniques that account for model uncertainty.
Congratulations on this significant scientific and publishing success!
