Keynesians - Beliefs

Keynes didn't agree with the Classical economists!! In fact the easiest way to look at Keynesian theory is to see the arguments he gave for Classical theory being wrong. In essence Keynes argued that markets would not automatically lead to full-employment equilibrium, but in fact the economy could settle in equilibrium at any level of unemployment. This meant that Classical policies of non-intervention would not work. The economy would need prodding if it was to head in the right direction, and this meant active intervention by the government to manage the level of demand.

Keynesian beliefs can be illustrated in terms of the circular flow of income. If there was disequilibrium between leakages and injections, then classical economists believed that prices would adjust to restore the equilibrium. Keynes, however, believed that the level of output (in other words National Income) would adjust. Say, for example, that there was for some reason an increase in injections (perhaps an increase in government expenditure). This would mean an imbalance between leakages and injections. As a result of the extra aggregate demand firms would employ more people. This would mean more income in the economy some of which would be spent and some saved (or paid in tax). The extra spending would prompt the firms in the economy to produce even more, which leads to even more employment and therefore even more income. This process would go on, and on, and on, and on until it stopped! It would eventually stop because each time income increased, the level of leakages (savings, tax and imports) also increased. Once leakages and injections were equal again, equilibrium was restored. This process is called the Multiplier effect.
