See you have this model: https://en.wikipedia.org/wiki/Computable_general_equilibrium https://en.wikipedia.org/wiki/Computable_general_equilibrium See this model "estimates how an economy might react to changes in policy, technology or other external factors." This model uses real data. Why use this model at all? Why not change the policy itself and see the effects of it in real time? If you can do that as you can in terms of some decisions which are reversible. If on the other hand that's not possible, why not validate this model continuously against the real market with every single policy to point to its weaknesses and failures? That's what big data allows you to do. That's all I was getting at.
