Experimental Research (PIERI) Datasets

This is a database of experimental impact evaluation projects undertaken by PEP-supported local researchers in developing countries. The data comes from impact evaluations conducted using the Randomized Controlled Trials and Field Experiments methodologies only. 

Currently, the database covers impact evaluations of interventions related to youth employment, women’s empowerment, access to credit, and cash transfer programs. Other impact evaluations addressing different policies will be added in time.   


Information collected 

For each impact evaluation, the database provides:

  • A quick description of the intervention under scrutiny, 
  • The evaluation design, 
  • The results of the impact evaluation (the results reported are significant at the 5% level, unless otherwise noted), 
  • A link to the document, if publicly available. 


Technical support 

The PIERI research group provides scientific support and capacity building to PIERI project teams via study visits, training workshops and online mentoring on conducting RCTs and field experiments. PIERI experts assist teams from the beginning to the completion of the evaluation project, addressing sampling strategy, questionnaire design, experimental design, data collection techniques, data analysis, report writing, dissemination, and policy outreach.
