As you can tell from the history of the model, Keynesian macroeconomics are very much focussed on demand insufficiency, and government intervention. This was a big deal in the Great Depression. However, the model does not look at supply constraints, and inflation, which means it only looks at the demand side of the equation.

In your view, how important - given recent events such as the COVID-19 pandemic - are supply-side issues to macroeconomics?

Consider a closed economy, where MPC is 0.8, which gives a government multiplier of 1 / 0.2 = 5

What happens to the efficiency of government intervention, if the MPC changes?

Consider a closed economy where MPC = 0.9, and AE = Ye₁ (equilibrium production level). However, potential output is larger, at 9,000 G$

Ye₁ = 8,000 G$

Yp = 9,000 G$

Calculate the Output Gap, and the necessary government stimulus, so that  Ye₂ = Yp.
