Summary: Comparing Cash and Voucher Transfers in a Humanitarian Context – Evidence from the Democratic Republic of Congo

Core Content

This paper presents a randomized experiment comparing the impacts of cash transfers and voucher transfers on internally displaced households in the Democratic Republic of Congo (DRC). The study is part of a broader effort to evaluate the effectiveness of different forms of social protection in humanitarian settings, where in-kind transfers are still widely used despite growing support for cash-based alternatives.

The research focuses on the extensive and intensive margins of household purchasing behavior and how these differ between the two transfer modalities. It also evaluates the cost-effectiveness of each approach for both the implementing agency and the recipients.

Main Points

• Context: The DRC has experienced prolonged conflict, leading to the displacement of millions. IDPs often reside in informal camps and rely heavily on external aid for basic needs.
• Program Design: A short-term social protection program was implemented, providing unconditional cash transfers (US$130 over 7 months) and equally valued vouchers to 474 IDP households. The cash was directly deposited into an interest-free account, while vouchers were redeemable at pre-organized fairs.
• Key Findings:
  • Purchasing Behavior: Cash households used their transfers more flexibly, purchasing a wide range of food and non-food items, including health and education expenses. Voucher households, on the other hand, were more constrained and focused on specific food items, such as salt, which are storable and easier to resell.
  • Food Consumption and Well-being: Despite differences in purchasing behavior, there were no significant differences in food consumption or other well-being indicators between the two groups.
  • Cost-Effectiveness: Cash transfers were found to be more cost-effective than vouchers, as the latter imposed transaction costs and limited choices, even though they were designed to be equivalent in value.
  • Voucher Limitations: The voucher program, while more restrictive, did not lead to better outcomes in terms of well-being, suggesting that the flexibility of cash is a key advantage in this context.

Key Information

• Transfer Value: Both modalities had a total value of US$130.
• Timing and Frequency: The transfers were distributed over a seven-month period, with three disbursements.
• Voucher Restrictions: The voucher program was more restrictive, especially in the second and third transfers, which were limited to food items only.
• Market Prices: Voucher fair prices were aligned with local market prices, and there were no systematic price differences between the two modalities.
• Target Population: The study focused on internally displaced households in an informal camp in the Masisi territory of DRC.
• Data Sources:
  • Household Surveys: Collected data on demographics, asset ownership, and food expenditures.
  • Price Data: Used to assess the value of assets and the prices faced by households.
  • Qualitative Data: Gathered from focus groups to complement quantitative findings.

Methodology

• Randomization: Households were randomly assigned to either the cash or voucher intervention, stratified by neighborhood.
• Estimation Strategy: A regression model was used to estimate the intent-to-treat (ITT) effect of the cash transfer. The model included neighborhood fixed effects and baseline covariates.
• Robustness Checks: The study accounted for attrition and used Lee bounds to ensure the validity of results. It also tested for differential attrition across groups and found no significant differences.

Conclusion

The study concludes that, in the context of humanitarian aid in the DRC, cash transfers are more cost-effective and flexible than vouchers, even though vouchers were designed to encourage specific purchases. The results highlight the importance of flexibility in aid distribution and suggest that in-kind transfers may not always be necessary or more beneficial than cash transfers, especially in contexts where local markets are accessible and program recipients are capable of making informed spending decisions.

Additional Notes

• The study emphasizes that voucher programs can lead to distortions in purchasing behavior due to constraints on use.
• It also notes that flexible voucher designs are more common in developed countries or urban settings, but less so in rural and humanitarian contexts.
• The paper contributes to the ongoing debate on cash vs. in-kind transfers by providing empirical evidence from a real-world humanitarian setting.
