Answer:
c. believe in the use of fiscal policy to stabilize the economy.
Explanation:
According to Keynesian theory, the sum of some micro-economic behaviors of all individuals and businesses results in inefficiency and the economy operates at a level below its potential output and growth. When total demand for products is insufficient, the economy enters a crisis and unnecessary unemployment arises due to defensive behavior of the producers. In such cases, the government may pursue policies to increase aggregate demand, and as a result may accelerate economic activities and reduce unemployment. Most Keynesian propose policies to stabilize the business cycle. For example, when the unemployment level is too high, the state can pursue a growth-oriented monetary policy. , one of the most famous of his critiques, Keynes argues and did not agree with "The Laissez-faire" that he opined the doctrines of laissez-faire are dependent on some extent on a case-by-case basis.
