In July 2011 Pakistan’s Benazir Income Support Programme (BISP) launched the national roll-out of its unconditional cash transfer programme aimed at providing the women and families of households in the bottom quintile of the income distribution. OPM designed and implemented a national Baseline Survey that will be followed by a number of impact evaluation surveys. A “pure experimental” survey design was not possible due to the nature of the programme’s rollout. Instead the design followed a combined approach using a Regression Discontinuity Design (RDD), complemented with a Propensity Score Matching (PSM) approach. Such a complementary approach allows for robust impact estimates at Province Level, with ability to triangulate estimates from each approach. Furthermore, this analysis can be supplemented with difference-in-difference techniques across baseline and follow-up surveys to understand impact on a range of household level poverty and welfare characteristics including: poverty status; coping strategies; labour participation rates; employment and underemployment; productive and non-productive assets; health and nutrition; education; water and access to amenities; savings and borrowing.
