Vertical Intercept of the Aggregate Demand Curve
When the aggregate demand function is graphed, its vertical intercept represents the level of autonomous demand. This intercept is the point where the aggregate demand line crosses the vertical axis and is calculated as the sum of autonomous consumption () and exogenous investment (). It signifies the total planned spending that would occur in the economy if aggregate income were zero.

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 ____.
Graphical Analysis of an Economy's Planned Spending
Axes and Properties of the Aggregate Demand Graph (Figure 3.12)
In a simplified model of a closed economy with no government sector, the consumption function is described by the equation C = 200 + 0.75Y, where C is total consumption and Y is total income. Planned investment (I) is fixed at 150. Based on this information, what is the total level of spending that would occur if national income were zero?
Components of Autonomous Spending
Analyzing Shifts in Autonomous Demand
In a simplified economic model where total planned spending is determined by consumption and investment, which of the following events would cause a change in the portion of total spending that is independent of the current level of national income?
In a simplified economic model where total planned spending consists of consumption and investment, a decrease in the marginal propensity to consume will lead to a decrease in the level of autonomous demand.
In a closed economy with no government, the aggregate demand function is given by the equation AD = 350 + 0.6Y. In this model, the value of autonomous demand is ____.
In a simplified economic model, a portion of total spending is determined by factors other than the current level of national income. This spending consists of autonomous consumption (spending not dependent on income) and planned investment. Match each economic event described below with its most direct impact on this type of spending.
The Role of Autonomous Spending in Economic Models
In a simplified economic model, the aggregate demand function is initially given by AD = 500 + 0.8Y. If a widespread decrease in consumer confidence causes the portion of spending that is independent of income to fall by 50, what will be the new aggregate demand function?

Adding Parents to 'Vertical Intercept of the Aggregate Demand Curve'
An economy is described by a consumption function and a given level of planned investment that does not change with income. If business leaders suddenly become more optimistic about future profitability, leading them to increase their planned spending on new factories and equipment, what is the immediate effect on the graphical representation of the economy's aggregate demand?
Calculating the Vertical Intercept of Aggregate Demand
In a simple macroeconomic model where total spending is composed of consumption and planned investment, the vertical intercept of the aggregate demand curve is determined solely by the level of spending that households would undertake even if their income were zero.
Economic Significance of the Aggregate Demand Intercept
Match each macroeconomic term with its correct description in the context of the aggregate demand model.
In a simple two-sector model of an economy, the vertical intercept of the aggregate demand curve represents the total planned spending when income is zero. This value is calculated by summing autonomous consumption and ________.
Deconstructing the Vertical Intercept of Aggregate Demand
In a simple economic model, the aggregate demand curve is plotted with total planned spending on the vertical axis and aggregate income on the horizontal axis. Suppose the government enacts a policy that increases the level of spending households would undertake even with zero income. Simultaneously, businesses become more pessimistic about the future and reduce their planned spending on new equipment by an exactly equal amount. What is the net effect on the vertical intercept of the aggregate demand curve?
A macroeconomist is building a simple model of an economy where total planned spending consists only of consumption and investment. Arrange the following steps in the correct logical sequence to determine the value of the vertical intercept for the economy's aggregate demand curve.
In a simple macroeconomic model where total planned spending is plotted against aggregate income, an increase in the proportion of each additional dollar of income that households choose to spend will cause a parallel upward shift of the entire aggregate demand curve, resulting in a higher vertical intercept.
