Sponsors: Thematic Group on Poverty Impact Analysis, Monitoring and Evaluation.

12:30 - 2:00 pm
Room MC11-670

Presenters: Howard White
Howard White, of the Bank's Independent Evaluation Group (IEG), will present findings from the recent impact evaluation of maternal and child health and nutrition in Bangladesh. The talk will focus on two aspects. The first is the use of secondary data for impact evaluation purposes. The study drew on DHS data to examine the impact of interventions from a range of sectors (female education and rural electrification as well as health), and combined the results of this analysis with unit cost data to produce estimates of cost effectiveness in saving lives. The talk with thus show that estimates are possible with secondary data, but will also highlight their limitations.

The second part of the talk will present results concerning the Bangladesh Integrated Nutrition Project. In this case a project evaluation dataset was available, but the control was of poor quality. Data from the nationally-representative Nutritional Surveillance Project were used to create a new control group using propensity score matching. The talk will also illustrate how the use of the theory-based approach helped identify weaknesses in project design and implementation.
