You've put your finger on a tremendously hard question, because elsewhere in the development world everybody is quite rightly expected to be rigorous about the impact they're having, but elsewhere they're doing things where they're trying to achieve quite a well-defined effect on quite a well-defined group of people. An example might be if you open a health clinic in a region that hasn't had a health clinic before, and you should expect to be able measure improvement in the health outcomes of the people in that area. Investment is very different from that. It's very rare that you have a well-defined group of people in whom you would expect to be able to measure a benefit, because economies are integrated. If you open a new restaurant in Toronto, you could set off a chain of events that sees somebody in Ottawa getting a job they wouldn't have got before.
In a simple economic model, which isn't realistic but might not be a bad place to start, adding one extra piece of investment to an economy raises wages across the entire economy by a small amount. That's an extremely hard thing for anybody who has the job of measuring the contribution of DFIs towards the sustainable development goals to put a number on. I don't think anybody sensible can doubt that the accumulation of investment is what takes a poor country from being unproductive and poor to being wealthy and productive. We know that the only way to go from poor to not poor is by accumulating investments, so I think you can have confidence that a DFI is contributing towards a sustainable development goal, but you are left with this difficult problem of how to measure and articulate that contribution.
At the moment, the DFIs all use something called the—and I've written down the acronym. They have agreed to a bunch of indicators to get a harmonized set of indicators, which I imagine would be sensible for the Canadian DFI to adopt. However, this is a very live discussion with all the DFIs at the moment, to try to find ways of capturing how they contribute to the transformation of the economies they invest in.
