Question

What factors will shift the \(A D\) curve in the simple Keynesian model?

Short answer

The factors that will shift the AD curve in the simple Keynesian model are changes in consumption, investment, government policies, and net exports.

Step-by-step solution

Analyze the impact of consumption on AD

Here, one should consider how changes in household consumption (C) can influence the AD curve. Any decrease or increase in consumer spending can cause the curve to shift left or right respectively. For instance, if consumers decide to save more and spend less, the reduction in spending will cause the AD curve to shift to the left. On the other hand, if consumers decide to spend more and save less, it will cause the AD curve to shift to the right.

Analyze the impact of investment on AD

Changes in investment (I) can also cause a shift in the AD curve. If businesses decide to cut back on their investments due to uncertainty in the economy, the AD curve will shift to the left. Conversely, if businesses decide to increase their investments, the AD curve will shift to the right.

Analyze the impact of government policies on AD

Changes in government spending (G) and tax policies can influence the AD curve. If the government decides to cut its spending or increase taxes, the AD curve will shift to the left. If the government decides to increase its spending or cut taxes, this increases spending power, and thus the AD curve will shift to the right.

Analyze the impact of net exports on AD

Net exports (NX), which is the difference between a nation's exports and imports, can cause shifts in the AD curve. If a country's exports increase or its imports decrease, the AD curve will shift to the right. Conversely, if a country's exports decrease or its imports increase, then the AD curve will shift to the left.
