Paul A SamuelsonBIG ISSUES OF ECONOMIC CONCERN Samuelson has offered the world numerous economic theories. One area he is widely known for is his views on the surpassing multiplier. Samuelson has presented a way through his aggregate select puzzle to demonstrate how the spending multiplier affects individual types of spending. There are several(prenominal) components of aggregate direct. The basis for understanding this model is as follows An increase in prices causes a drop in household assets, thus causing consumers to spend less. Increases in domestic prices reduce exports, which causes an increase in spending on imports. The interest rate effect is when prices increase, as does the demand for money, thus increase the interest rate. This forces a downward pressure on investment and purchases of unchangeable goods. Therefore, investment, exports and consumption are all inversely related to pricing. In Samuelsons model, government spending was the only constant. This means the government will eer buy the same amount of goods no matter what the price.The aggregate demand schedule is therefore, the sum of consumption, investment, government purchases and exports.
