Review Questions
Explain how Keynes' perspective on market forces differs from the classical economic view.
Keynes challenged the classical economic view that the economy would naturally reach full employment equilibrium through the self-correcting mechanisms of the market. Instead, Keynes argued that during economic downturns, aggregate demand could fall, leading to high unemployment and underutilization of resources. He believed that government intervention through fiscal policy, such as increased spending and tax cuts, could be necessary to stimulate aggregate demand and boost economic activity, in contrast to the classical view that the market would self-correct.
Describe how Keynes' ideas about aggregate demand and Keynes' Law relate to the AD/AS model.
Keynes' analysis of aggregate demand and its role in determining economic outcomes is central to the AD/AS model. Keynes argued that aggregate demand, rather than just supply, plays a crucial role in determining the level of economic activity and employment. Keynes' Law, which states that 'demand creates its own supply,' suggests that increases in aggregate demand can lead to increases in output and employment, rather than just higher prices. This contrasts with the classical view embodied in Say's Law, which holds that supply creates its own demand. Keynes' ideas about the importance of aggregate demand and the potential for government intervention to manage it are fundamental to the Keynesian perspective on the AD/AS model.
Analyze how Keynes' views on fiscal policy and its impact on the trade balance differ from the classical economic perspective.
Keynes' emphasis on the role of fiscal policy in managing the economy is a key aspect of his economic thought. Keynes argued that during economic downturns, government intervention through increased spending and tax cuts could stimulate aggregate demand and boost economic activity. This contrasts with the classical view that the market would naturally self-correct. Keynes' ideas about fiscal policy have important implications for the trade balance. He believed that government spending could increase domestic demand, leading to higher imports and a deterioration of the trade balance. This is in contrast to the classical view that trade balances would naturally adjust through changes in exchange rates and relative prices. Keynes' perspective on the role of fiscal policy and its potential impact on the trade balance has been influential in shaping economic policymaking, particularly during periods of economic instability or recession.
An economic theory developed by Keynes that emphasizes the role of government intervention and active fiscal policy in stabilizing the economy and promoting full employment.
