A novel multi-criteria approach for evaluating social discrimination in OECD countries

The Organisation for Economic Co-operation and Development (OECD) was established to unite countries from different geographical regions to achieve prosperity and economic progress. Different geographical regions have different cultures. The sociological perspective on gender varies in these cultures. As a result, gaps occur in terms of gender discrimination and its dimensions between countries. While social progress is a prerequisite for economic progress, society must be in harmony for social progress. The Social Institutions and Gender Index (SIGI) was developed to measure progress in different countries. This study proposes a Multi-Criteria Decision-Making (MCDM) model over the SIGI index to measure gender discrimination levels in OECD countries. However, since the differences in gender discrimination resulting from the multicultural structure of OECD lead to significant variability in terms of countries, countries are first clustered. Then, SIGI criteria significance levels are evaluated with a novel Importance of Criteria’s Indifference to Normalization (ICIN) method based on the differences between the two normalization approaches. Subsequently, a novel Modified Extended Alternative Ranking Order Method Accounting for Two-Step Normalization (ME-AROMAN) approach is employed to rank the member countries. While discrimination in the family is the most prominent factor for countries better at social equality and access to productive and financial assets is the major factor that separates the countries worse at social equality, the sensitivity and comparative analysis demonstrate the applicability and validity of ICIN and ME-AROMAN in MCDM literature.
