Question

Quizplus · Accepted Answer

Keynesian economics advocates for increased government involvement and intervention in the economy, whereas traditional laissez-faire policies argue for minimal government interference in the free market. Adam Smith, a key proponent of laissez-faire, believed that markets should be self-regulating and that government intervention would only impede economic growth. Keynes, on the other hand, argued that the government should use fiscal and monetary policies to smooth out economic booms and busts and promote full employment. These policies often include government spending, taxation, and interest rate adjustments.
