In a closed economy with no government sector, the consumption function is C = 150 + 0.8Y, where Y is income. Initially, planned investment is fixed at 250. If a change in business confidence causes planned investment to fall to 200, what is the new slope of the aggregate demand curve?

Determinants of the Aggregate Demand Slope

In an economic model where total demand is the sum of consumption and a fixed level of investment, an increase in the fixed level of investment will cause the aggregate demand curve to become steeper.

Analyzing Changes in Aggregate Demand

In an economic model, total demand is the sum of consumption and investment. The consumption function is given by C = 200 + 0.75Y, where Y is total income. Investment is fixed at a value of 100. What is the slope of the aggregate demand curve in this model?

In an economic model where total demand is the sum of consumption and a fixed level of investment, the slope of the aggregate demand curve is determined solely by the __________.

In an economic model where aggregate demand is the sum of consumption and a fixed level of investment, match each economic change to its corresponding effect on the aggregate demand curve when graphed against national income.
