How do we find the TRUE CAUSE of what happens? When Momo drinks a special smoothie and wonders, "but how do we REALLY know if it makes me jump higher?", she and her twin Puri discover the economist's secret: comparing "what is" with "what would have been." Playground adventures that teach the same tools economists use to find answers. Prepare for "aha!" moments at any age! Building tomorrow's problem-solvers, one story at a time. This is Volume 1 of the Impact Evaluation Series for Children and a brief introduction to the concept of Counterfactuals in Research Design and Methodology.
