Building an economy simulator from scratch
OT: I see economists of various ideological tilts constantly arguing about how macroeconomic variables will respond to specific government policies. You know: "this new tax will increase inflation; no it will not, it will increase unemployment".<p>What I don't get is why there are no readily available online macroeconomic simulators with real world data that make these sort of predictions. For a lot of countries, up-to-date macroeconomic and demographic is readily available.<p>Surely, economists of every ideological tilt have their own standard model of macroeconomics [1] which they use to make rough predictions? If not, how complicated is it really?<p>[1] Much like the standard model of particle physics or of cosmology. Fairly dirty and complicated models with lots of tunable parameters.
