Goods Market Equilibrium in an Open Economy with Government (Figure 3.16)

Consider a graph where the vertical axis represents planned aggregate expenditure and the horizontal axis represents aggregate income (output). A 45-degree line shows all points where expenditure equals income. An upward-sloping aggregate demand (AD) curve, which is flatter than the 45-degree line, is also plotted. If the current level of output is to the right of the intersection point of the AD curve and the 45-degree line, which of the following statements accurately describes the state of the economy and the resulting adjustment?

Impact of Increased Autonomous Spending

Analyzing Disequilibrium in the Goods Market

In the standard graphical model for determining equilibrium output, where the vertical axis is planned aggregate expenditure and the horizontal axis is aggregate income/output, match each graphical element with its correct economic description.

In the graphical model where planned aggregate expenditure is plotted against aggregate income, every point along the upward-sloping aggregate demand (AD) curve represents a possible equilibrium level of output for the economy.

Explaining the Graphical Determination of Equilibrium Output

Consider a graphical model of the goods market where the aggregate demand (AD) curve intersects the 45-degree line to determine equilibrium output. If the current level of aggregate income (Y) is less than the equilibrium level, firms will observe that demand for their goods exceeds their current production. Arrange the subsequent sequence of events that will lead the economy back to equilibrium.

In the graphical model of the goods market, the equilibrium level of output is determined by the intersection of the aggregate demand curve and the 45-degree line. This intersection signifies the unique point where planned aggregate expenditure is precisely equal to ________.

Analyzing a Shift in Aggregate Demand

Consider two closed, private economies, Economy A and Economy B, represented on identical aggregate expenditure graphs. Both economies have the same level of autonomous spending (the vertical intercept of the aggregate demand curve is the same). However, the citizens in Economy A have a higher marginal propensity to consume than the citizens in Economy B. Based on the graphical model where equilibrium is determined by the intersection of the aggregate demand curve and the 45-degree line, which of the following statements is the most accurate evaluation of their respective equilibrium states?
