Income impact is the capstone of the Millennium Challenge Corporationâ€™s â€œcontinuum of resultsâ€ framework. Independent evaluations are the most rigorous means of measuring that impact and at the heart of MCCâ€™s commitment to accountability, learning, transparency, and evidence-based decision making. Independent evaluations, which are conducted by third-party independent experts, help answer three fundamental questions:
- Was MCCâ€™s investment implemented according to plan? This is key to transparency.
- What are the changes in income for program participants that are attributable to MCCâ€™s investment? This is key to accountability.
- Why did or didnâ€™t the planned investments lead to changes in income? This is key to learning
Impact and Performance
Impact evaluations are the most rigorous form of evaluations because they make it possible to know whether the observed impacts were caused specifically by an MCC investment or, alternatively, are the result of external factors that affected program participants and non-participants, like increased market prices for agricultural goods, national policy changes or favorable weather conditions. Impact evaluations compare what happened with the MCC investment to what would have happened without it, through the use of a counterfactual.
Performance evaluations are a valuable tool for estimating the contribution of MCC investments to changes in trends on outcomes, including farm and household income. Performance evaluations are less rigorous and cannot attribute causal impact to MCC investments because they do not use a counterfactual. However, they are useful to compare changes in the situation before and after MCCâ€™s investment and provide details on how an investment might have contributed to changes in beneficiary income, how it might have contributed to changes in outcomes and why.
How We Choose
There are several critical factors that MCC considers when deciding to invest in an impact or a performance evaluation:
- Learning potential: For programs where the assumptions underlying the project logic are based on limited evidence, there is a strong case for an impact evaluation. A rigorous impact evaluation tests assumptions about a projectâ€™s effectiveness and contributes substantially to MCCâ€™s future decision-making, as well as the global evidence base.
- Feasibility: The feasibility of designing and implementing a strong impact evaluation is based on how well the evaluators are able to estimate a counterfactual and how feasible it is to maintain that counterfactual through the duration of the evaluation period.
- Strong stakeholder commitment: Identifying a control group and ensuring adherence to an impact evaluation design require significant commitment and collaboration by sector staff, program implementers and evaluators, both within MCC and among partner countries.
- Appropriate timing: The evaluation timeline must be informed by the project logic, particularly with regard to assumptions about how long it will take for expected impacts to occur. By collecting data too early, evaluations may underestimate the impacts on outcomes of interest or miss important lessons.
- Proper coordination: Evaluations require close coordination with program implementation. Program designers, implementers and evaluators must work together to understand and define the program logic, estimate how long expected impacts are likely to take to accrue and identify what is most important to learn about how the program works. This is particularly true for impact evaluations, which require coordination and commitment among various stakeholders to estimate a counterfactual.
Incorporating evaluationsâ€”particularly impact evaluationsâ€”into program operations is not easy, but this is a challenge that MCC embraces to ensure accountability for results and to improve learning on what works. This commitment to evaluation helps distinguish MCC in the international development community.
An impact evaluation is defined by the ability to estimate the counterfactual, what would have happened to the same group of program participants if they had not received MCCâ€™s assistance. The most rigorous method for estimating the counterfactual to measure attributable program impacts is through randomized control trials. In many programs, there are financial and/or logistical constraints to providing all eligible individuals or groups with an intervention. Random selection (such as through a lottery) is a fair and transparent way to select which eligible individuals or groups should receive the intervention first.
Because randomized control trials randomly select individuals that will and will not be exposed to program benefits, evaluators can compare the groups to measure their impacts. This use of a statistically identical control group creates the greatest opportunity for learning what works and for measuring program impacts.
When a randomized control trial is not feasible, MCC may use other methods to construct a credible comparison group, such as a propensity score matching, difference in differences or regression discontinuity.
