 Workstream 4 covers macroeconomic policy and macroeconomic policy modelling. So most things that relate to macroeconomic policy, macro-fiscal policy and research would be covered in there. One of the things that I think would be an interesting innovation in this iteration of SA Tide is some cross-cutting work that might work even beyond the core priorities of Workstream 4, but are really important for how we think about economic policy more generally and sort of some synergies across different disciplines of economics. So macroeconomic policy, macroeconomic policy, econometrics and how these things sort of work together. I think what we are specifically looking at are three things. The first is the generation of new knowledge in these particular fields. So South Africa is faced by a number of issues. As a country we have government debt problems, public debt problems, and we have a number of challenges from overseas spilling over into South Africa, you know, in countries like the US and the UK currently suffering from higher inflation and the questions are whether that will spill over into South Africa. There's also questions about tax buoyancy, for instance, and, you know, if income in the country goes up or down, what effect does that have on the collection of the revenue by the government? So these are sort of the questions we need to look at and really expand on that frontier, that knowledge frontier. The second aspect that we really want to look at is the creation of capacity, capacity specifically, and then thirdly, we want to ensure proper communication and engagement with the policy environment. So very often academics do a lot of work, but that does not necessarily spill over into the policy realm. And we want to improve that flow of information. Fundamentally, we hope to achieve, I think, the core idea of the essay type program, and that's creating this interface between very good evidence-based quality research and policy formulation and ensuring that these two things speak together in a way that's policy relevant. And I think what this work stream will be doing is ensuring that we're answering that question from a macro-fiscal perspective or a macro-normal policy perspective, but also doing it in a way that builds lasting capacity in institutions, which I think is critically important.
