In a simplified economy, firms produce a total output valued at $800 million. During the same period, total planned spending (the sum of what households plan to consume and what firms plan to invest in new capital) is calculated to be $780 million. Based on the conventions of national income accounting, how does this situation affect business inventories?

Planned vs. Unplanned Investment

In a macroeconomic model where equilibrium occurs when total output equals total planned expenditure, a situation where businesses sell more goods than they produced during a period results in a positive and planned inventory investment.

The Role of Unplanned Inventories in Economic Adjustment

Match each economic scenario with the resulting change in business inventories, based on the principle that all inventory changes are considered unplanned.

In a given period, an economy's firms produce a total output of $500 billion. During the same period, the total of all planned spending (by households, firms for new capital, and government) amounts to $520 billion. What is the immediate result for business inventories, and what does this signal to firms about future production levels?

An economy is initially in a state where total production exceeds total planned spending. Arrange the following events in the logical sequence that describes how the economy adjusts.

In macroeconomic models, the difference between the total value of goods and services produced in an economy and the total amount of planned spending is defined as ____ inventory investment.
