This morning I have been reading, with interest, Giel Ton's 2020 paper: Development policy and impact evaluation: Contribution analysis for learning and accountability in private sector development
1. Description: Spend time describing the many forms of impact a particular intervention is having. I think the technical term here is multifinality. In a private-sector development programme, multifinality is an extremely likely phenomenon. I think Giel has in effect said so at the beginning of his paper: " Generally, PSD programmes generate outcomes in a wide range of private sector firms in the recipient country (and often also in the donor country), directly or indirectly."
Two examples, one contemporary, one very old: If someone could give me a predictive model of sharemarket price movements that had even a modest 55% accuracy I would grab it and run, even though the likelihood of finding any associated causal mechanism would probably be very slim. Because I’m not a billionaire investor, I have no expectation of being able to use an explanatory model to actually change the way markets behave. But I do think I could respond in a timely way if I had relevant predictive knowledge.
2021 02 19: I have just come across a special issue of the Evaluation journal of Australasia, on the subject of values. Here is the Editorial section.
