The 45-Degree Line as a Representation of Goods Market Equilibrium

An economy is in a stable state where the total value of goods and services being produced each month is equal to the total amount being purchased. Which of the following independent events would cause the economy to move to a new, different stable state?

Economic Adjustment to Disequilibrium

Assessing Economic Stability

In the context of a simple economic model where total spending determines total output, if businesses observe that their inventories of unsold goods are unexpectedly increasing, it signifies that the economy is in a stable, self-perpetuating state.

Calculating Equilibrium Output

Characteristics of Economic Equilibrium

An economy is currently producing a total output of $500 billion. At this level of output, the total planned spending (aggregate demand) by households and firms is also exactly $500 billion. Assuming no external changes to spending behavior or investment plans, what is the most likely outcome for the economy's total output in the subsequent period?

In a closed economy with no government, suppose that the total value of all goods and services produced in a given period is $800 billion. However, the total planned spending by households and firms during the same period is only $750 billion. Based on this information, what is the most likely immediate consequence for the economy?

Analyzing Economic Stability

Match each economic scenario, defined by the relationship between total output (Y) and aggregate demand (AD), with its most likely consequence for business inventories and future production decisions.
