Randomized controlled trials (RCTs) are the basic most bias-free impact evaluation method. The units of analysis (frequently being people) are randomly assigned to a so-called treatment group, i.e. the group exposed to certain policy intervention (e.g. active labor market policy, or training), while the rest serve a control group. Then, pre-selected outcomes (e.g. employment or wages) are compared between the two groups.
Rachel Glennerster and Kudzai Takavarasha developed an excellent Practical Guide for RCTs. The Partnership for Economic policies developed a toolbox “Impact Evaluation Using Stata“
Finance Impaq is deeply engaged in understanding the mechanism of work of processes and programs and hence is able to apply rigorous and up-to-date econometric methods to reveal the effects of such processes and programs.
Finance Impaq relies on Stata for conduct of impact evaluations.
