Economic Inequality in the Arab Region Summary

Core Content

This paper, authored by Nadia Belhaj Hassine and published by the World Bank in 2014, provides a detailed analysis of economic inequality in 12 Arab countries using harmonized household survey micro-data. The study focuses on the sources of inequality between urban and rural areas, as well as between metropolitan and non-metropolitan regions, and applies the unconditional quantile regression decomposition technique to understand the welfare gaps across the entire distribution of household expenditures.

Main Points

• Inequality Levels: The Gini coefficient for household real per capita total expenditures ranges between 30.7 in Libya and 45 in Mauritania, indicating moderate levels of inequality across the Arab region.

• Trends in Inequality: Inequality has persisted in most Arab countries and has increased in Mauritania, Syria, and Yemen by the mid-2000s. The Arab region's inequality levels have remained relatively stable compared to other developing regions, with only slight changes in some countries.

• Determinants of Inequality: The main sources of inequality are differences in households' endowments, such as demographic composition, human capital, and community characteristics. Urban-rural inequality is primarily driven by the better endowment of urban households with marketable characteristics, while metropolitan-non-metropolitan inequality is influenced by higher returns to household attributes in metropolitan areas.

• Historical Context: Following independence in the 1940s, the Arab region saw significant improvements in human development indicators and a reduction in poverty and inequality, mainly due to public investments in infrastructure, health, and education, as well as high oil prices and remittances. However, these gains started to erode in the mid-1990s due to declining oil prices, bloated public sectors, and reduced migration opportunities.

• Development Model: The traditional state-led development model, which emphasized public investment and social welfare, contributed to low poverty and relatively equal income distribution. However, this model has become less effective in recent years, leading to growing inequality and social unrest.

• Policy Implications: Understanding the sources and extent of inequality is crucial for designing inclusive growth strategies and addressing the concerns of the most vulnerable populations. The study emphasizes the need for policy reforms that can reduce regional and inter-group disparities and promote more equitable development.

Key Information

• Data Sources: The study uses 28 household surveys from 12 Arab countries, including Djibouti, Egypt, UAE, Iraq, Jordan, Lebanon, Libya, Mauritania, Palestine, Syria, Tunisia, and Yemen.

• Methodology: The analysis employs the Recentered Influence Function (RIF) regression approach to decompose inequality across the entire distribution of consumption expenditures. It isolates the contributions of geographical differences in household attributes from differences in returns to these attributes.

• Welfare Measures: Consumption expenditures are used as a proxy for welfare, with three expenditure aggregates considered: food only, food and non-durable goods, and total expenditures including housing and durable goods.

• Comparative Analysis: The study compares inequality levels in the Arab region with other developing regions. While the Arab region has maintained moderate inequality, some countries like Tunisia and Morocco have shown relatively higher levels, and the region has not outperformed Latin America in terms of economic equality when using income-based inequality measures.

• Challenges: The lack of harmonized and comparable micro-data on income and the political sensitivity of poverty and inequality issues have limited detailed analysis in the region. The paper aims to address this gap by using harmonized data and a comprehensive decomposition approach.

Conclusion

The paper highlights the importance of understanding the structural determinants of economic inequality in the Arab region, particularly the role of geographical disparities in household attributes and returns to these attributes. It underscores the need for inclusive growth policies that can address these inequalities and prevent further social tensions. This is the first comprehensive study to analyze economic inequality across a large panel of Arab countries using harmonized household survey data.
