What is causal attribution? Do you need a counterfactual to determine if something has caused a change?
Professor Patricia Rogers provides an overview of how to determine causal attribution in impact evaluations.
She covers three broad strategies for causal attribution:
- Estimating the counterfactual;
- Checking the consistency of evidence for the causal relationships made explicit in the theory of change; and
- Ruling out alternative explanations through a logical, evidence-based process.
Can you tell us a bit more about natural experiments? Do they typically include a before-after comparison or are there cases where randomization is used?
Is it possible to do a meta-evaluation of evaluations which used different strategies for causal attribution?
Do you have some example of indicators for consistency between e.g. counterfactual and case study. How can this modus operandies be analyzed?
