Applying the National Income Identity
In a simplified economy, a company produces $10 million worth of goods. Consumers purchase $8 million of these goods. The remaining $2 million worth of goods are added to the company's inventory. Using the principle that total output must equal total expenditure by definition, explain how the national income accounting identity holds true in this scenario.

GDP Expenditure Formula (National Income Identity)
National Income Identity in a Closed Economy without Government
An economist makes two statements about a simplified economy's total output (Y):
Statement A: Y ≡ C + I_p + I_u (where C is consumption, I_p is planned investment, and I_u is unplanned inventory investment)
Statement B: Y = C + I_p (where C + I_p represents total planned expenditure)
Which of the following correctly analyzes the relationship between these two statements?
Analyzing Economic Statements
Applying the National Income Identity
The statement 'Total Output = Total Expenditure' is a fundamental accounting rule that holds true at all times, even when firms experience unexpected changes in their inventories.
Match each macroeconomic equation with the statement that best describes its nature. (Assume a simple closed economy where Y=Output/Income, C=Consumption, S=Saving, I_p=Planned Investment, I_u=Unplanned Investment, S_p=Planned Saving)
Definitional vs. Conditional Economic Relationships
In a given year, a simplified closed economy without a government experiences a situation where firms' total production (Y) exceeds the total amount of goods and services that consumers (C) and firms (for planned investment, I_p) intended to buy. Which of the following relationships holds true by definition as an accounting rule in this specific scenario?
Correcting an Economic Misconception
An economist analyzes a simplified economy and finds that total production for the year was $10 trillion, while planned consumption was $7 trillion and planned investment was $2 trillion. The economist concludes: "Since planned spending ($9 trillion) does not equal production ($10 trillion), the fundamental accounting rule that 'Total Output is definitionally equal to Total Spending' is violated in this case."
Which of the following provides the most accurate critique of the economist's conclusion?
