An economy experiences a sudden, one-time increase of $50 billion in autonomous investment spending on new factories. Assuming no other changes, what is the most likely ultimate effect on the economy's total output as described by the multiplier model?

Comparing Economic Responses to a Spending Shock

A wave of pessimism about the future of the economy causes firms to significantly reduce their spending on new machinery and buildings. According to the logic of the multiplier model, arrange the following events in the chronological sequence that would follow this initial shock.

Analysis of the Economic Amplification Effect

Explaining the Amplification of Spending

According to the multiplier model, if a government reduces its spending by $100 million to balance its budget, the total output of the economy will also decrease by exactly $100 million, as the reduction in demand is directly offset by the decrease in government expenditure.

Match each stage of the economic process described below with its correct description, illustrating how an initial change in spending is amplified.

In a simplified economy, a firm spends an initial $1,000 on new machinery. This $1,000 becomes income for the machinery's producers. If these producers, in turn, spend 80% of this new income on other goods and services, this second round of spending will add an additional $____ to the economy's total demand.

Evaluating Economic Stimulus Policies

An economy experiences a $10 billion increase in autonomous investment. In which of the following scenarios would this initial change in spending lead to the largest total increase in national output?

Demand-Determined Output Assumption of the Multiplier Model

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.
