Keynesians believe that the solution to a recession is expansionary fiscal policy,such as tax cuts to stimulate consumption and investment, or direct increases in government spending, either of which would shift the aggregate demand curve to the right. One of the main problems with the output gap is that it is hard to measure. It is on us today to even the odds and give everyone no matter where they are born the chance of a good life.
