Slope of the Aggregate Demand Curve in the Simplified Model
In the simplified multiplier model, the slope of the aggregate demand curve is determined solely by the marginal propensity to consume (). This is because investment is treated as a constant, exogenous value, meaning it does not change with income and therefore does not influence the curve's slope. As a result, the rate at which aggregate demand changes in response to income is governed only by .

Vertical Intercept of the Aggregate Demand Curve
Slope of the Aggregate Demand Curve in the Simplified Model
In an economy, total planned spending is the sum of consumption and a fixed amount of planned investment. If business leaders become more pessimistic about the future and consequently reduce their planned investment spending, how would this change be depicted on a graph with total planned spending on the vertical axis and aggregate output on the horizontal axis?
Deriving the Aggregate Demand Curve's Properties
Evaluating an Economic Claim with a Graph
In an economic model, total planned spending is the sum of consumption and planned investment. Consumption spending is known to increase as total income rises. Initially, planned investment is assumed to be a fixed amount that does not change with income. If this assumption is changed so that planned investment also increases as total income rises, how would the graphical representation of the total planned spending curve be affected?
In a simple economic model, total planned spending (AD) is given by the equation AD = 150 + 0.6Y + 250, where Y is aggregate output. Match each conceptual component of this model's graphical representation with its correct numerical value or description.
On a graph with total planned spending on the vertical axis and aggregate output on the horizontal axis, the line representing the consumption function and the line representing total planned spending (aggregate demand) will have different slopes because planned investment is included in aggregate demand.
Interpreting the Aggregate Demand Graph
An economist wants to draw the aggregate demand curve for a simple economy on a graph with aggregate output on the horizontal axis. They start with a pre-existing line representing the consumption function and are given a single, constant value for planned investment. Arrange the following steps in the correct logical sequence to accurately construct the aggregate demand curve.
In a simple economic model, the consumption function is represented by a line with a slope of 0.75. If a constant level of planned investment is added to this consumption function to derive the total planned spending (aggregate demand) curve, the slope of the resulting aggregate demand curve will be ____.

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.
