Economics - Essay Example The policies undertaken by governments in different economies are highly influenced by his theories even today. The theories introduced by Keynes mainly concentrate in the nature of total spending in the economy. The theories also analyze the influence of aggregate demand in economies inflation and output level. According to Keynes the aggregate demand created in the economy is often not equal to the productive capacity of the economy. Keynesian theories were introduced during Great Depression in the economy. Keynesian theory supports a mixed economic system, where the main sectors of the economy are headed by private business entities but are guided under the rules and regulations of the government at times of recession (Keynes, 1979). New Classical Theories of Economics New Classical theories of economics are consisted with the economic views of the modern contemporary economists. The theories mainly concentrate in the price, output and determination of income distribution in the e conomic system.

It assumes that economic entities in the world undertake their economic decisions after getting equipped with the underlying relevant information.

It was analyzed by Keynes theory that only changes in the aggregate demand, could improve the state of a depressed economy. Figure 1 - Keynesian Horizontal AS curve CPI AD p AS q Real GDP (Source: Author’s Creation) The graph above illustrates the AD and AS curve in Keynes views. The consumer price index (CPI) is the average price level of all the goods and services produced in the economy. AD is inversely proportional to CPI as per the law of demand. The market equilibrium price (p) an d equilibrium quantity (q) of real GDP generated in the economy are determined from the point of intersection between the AD and AS curves.
