Distributive Impacts of Social Protection Systems in OECD Countries: Public-Private Mix and the Hidden Welfare States

We constructed our unbalanced panel data set of 26 countries with 5 periods spanning from 1990 to 2014 solely based on the OECD.Stat data base, including the SOCX database for social expenditures. Each period consists of consecutive 5 years, and we take the simple averages for each period because the data of income inequality and net social expenditures are not available every year.
