Shapley-Value Decompositions of Changes in Wage Distributions: A Note
This note shows how the Shapley-value can be applied to the regression-based methods that are often used to decompose changes in wage distributions. The method remedies the path-dependency exhibited by existing approaches that compute the contributions due to (i) changes in sample observable characteristics, (ii) changes in the return of characteristics, (iii) changes in the distribution of unobservable characteristics.
