Then, the MPC is 0.8 and the MPS is 0.2. Thus, when income increases by $1,000, consumption rises by $800 and savings rises by $200.

Why does Keynesian economics argue that lower wages can restore full employment?
For example, Keynesian economics disputes the notion held by some economists that lower wages can restore full employment because labor demand curves slope downward like any other normal demand curve. Instead he argued that employers will not add employees to produce goods that cannot be sold because demand for their products is weak. Similarly, poor business conditions may cause companies to reduce capital investment, rather than take advantage of lower prices to invest in new plants and equipment. This would also have the effect of reducing overall expenditures and employment.

What is Keynes' theory of inflation?
Keynesian economics represented a new way of looking at spending, output, and inflation. Previously, what Keynes dubbed classical economic thinking held that cyclical swings in employment and economic output create profit opportunities that individuals and entrepreneurs would have an incentive to pursue, and in so doing correct the imbalances in the economy. According to Keynes’s construction of this so-called classical theory, if aggregate demand in the economy fell, the resulting weakness in production and jobs would precipitate a decline in prices and wages. A lower level of inflation and wages would induce employers to make capital investments and employ more people, stimulating employment and restoring economic growth. Keynes believed that the depth and persistence of the Great Depression, however, severely tested this hypothesis.
Why did Keynes see excessive saving as dangerous?
He saw it as dangerous for the economy because the more money sitting stagnant, the less money in the economy stimulating growth. This was another of Keynes's theories geared toward preventing deep economic depressions.
Why is the Simple Keynesian Model important?
The Simple Keynesian Model is important not so much for its ability to capture the details of recessions, but for its ability to demonstrate the possibility of a stable equilibrium at less than full employment. While the real wage rate adjusts in the Classical Model to move the economy to full employment, the real wage rate does not appear in the Simple Keynesian Model and equilibrium is achieved by adjustments in aggregate demand, which equals aggregate income. The equilibrium aggregate income need not imply full employment.
