Determinants of the Aggregate Demand Curve's Slope in the Comprehensive Model
In a comprehensive economic model, the slope of the aggregate demand curve is not solely determined by the marginal propensity to consume (). It is also influenced by the tax rate () and the marginal propensity to import (). These factors collectively determine the value of the multiplier, which in turn dictates the steepness of the aggregate demand curve.

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.

An economy's aggregate demand curve is plotted with total spending on the vertical axis and national income on the horizontal axis. Its slope is determined by how much of an additional dollar of national income is spent on that economy's domestic goods and services. Consider two distinct economies:
- Economy A: The marginal propensity to consume is 0.9, the income tax rate is 20%, and the marginal propensity to import is 0.1.
- Economy B: The marginal propensity to consume is 0.7, the income tax rate is 20%, and the marginal propensity to import is 0.3.
Which statement correctly analyzes the relationship between their aggregate demand curves?
Policy Impact on Aggregate Demand Slope
Evaluating Policy Options
Consider an economy where the marginal propensity to consume is 0.8 and the marginal propensity to import is 0.1. If the government increases the income tax rate from 10% to 20%, the aggregate demand curve (plotted with aggregate demand on the vertical axis and national income on the horizontal axis) will become steeper.
