What is the Keynesian Aggregate Expenditure Model?

The Keynesian model is like a picture that helps us understand how the money spent in a country affects the things it makes. This idea was thought up by a smart economist named John Maynard Keynes from Britain.

In the model, we look at two things: how much money is spent (up and down on the picture) and how much stuff the country makes (side to side on the picture). When these two things are equal, we say the economy is balanced.

The model helps us figure out the level of stuff a country makes when the money spent matches the stuff produced. This is important because it tells us how many jobs there will be.
