Summary of "Evaluating the Impact of Egyptian Social Fund for Development Programs"

Core Content

This working paper evaluates the impact of the Egyptian Social Fund for Development (SFD) on poverty reduction, employment, and access to basic services. The study uses data from the 2004/2005 national Household Income, Expenditure, and Consumption Survey (HIECS) and applies propensity-score matching to assess the causal effects of SFD interventions. The SFD was established in 1991 to support community development and microcredit programs, with a total disbursement of about $2.5 billion by 2008.

Main Programs and Activities

The SFD operates through several main programs, which are summarized in Table 1:

The SFD allocated 62% of its budget to community development, 9% to microcredit, and 28% to public works. The remaining funds were used for minor programs and administration.

Key Findings

• Educational interventions reduced illiteracy.
• Health and potable water programs lowered household spending on health and sanitation.
• Sanitation interventions cut sanitation costs and reduced poverty.
• Road projects reduced transportation costs by 20%.
• Microcredit increased household expenditures in metropolitan areas and urban Upper Egypt, but had no significant impact in other regions.

Cost-Benefit Analysis

• Roads and health and water interventions generated benefits that exceeded costs.
• Education and sanitation interventions showed less clear cost-effectiveness.
• The SFD's mission is socially oriented, not profit-driven, and thus should not be judged solely by cost-benefit analysis.

Targeting and Pro-Poor Orientation

• The SFD's programs are targeted to poorer areas, where outcomes such as literacy, health, and poverty are worse.
• The pro-poor orientation is strongest in microcredit, while other programs have a more modest effect.
• Poverty rates are higher in areas with SFD interventions, which suggests that the Fund is more likely to target the poor.

Methodology

The study uses propensity score matching to estimate the average treatment effect (ATE) by comparing villages with and without SFD interventions. The methodology also includes a common-impact model as a robustness check.

Propensity Score Matching

• A propensity score is a summary measure of the probability of a village being assigned to the treatment group (i.e., receiving an SFD intervention).
• The method ensures that treated and control units are similar in pre-treatment characteristics, allowing for a more accurate estimation of the impact.
• The region of common support is defined as the overlap in propensity scores between treated and non-treated units, ensuring valid causal inferences.

Balancing

• To ensure balance, the study checks that the distribution of covariates (such as age, literacy, and village characteristics) is similar between treated and non-treated groups.
• If balance is not achieved, the assignment model is revised.

Counterfactual Comparisons

Three types of counterfactual comparisons are used:

1. A vs. B: Compares villages with and without SFD interventions, assuming other interventions are likely to occur in the absence of SFD.
2. D vs. F: Compares villages with only SFD interventions to those with no interventions at all.
3. C vs. E: Compares villages with both SFD and other interventions to those with only other interventions, capturing synergistic effects.

Conclusion

The SFD has had clear and measurable effects on poverty, employment, and access to basic services. The most effective interventions were in roads, health, and potable water, while microcredit showed strong pro-poor effects in specific regions. The study underscores the importance of impact evaluation in understanding the effectiveness of social development programs, especially in the context of resource allocation and policy design.
