Decomposition of GDP by Expenditure

In a simple economy, a farmer sells wheat to a miller for $50. The miller grinds the wheat into flour and sells it to a baker for $80. The baker then uses the flour to bake bread, which is sold to a consumer for $120. Based on these transactions, what is the contribution to the economy's total output as measured by the total spending on final goods and services?

Calculating Contribution to Total Output

Analyzing Transactions for Total Output Measurement

To accurately measure a country's total output for a specific year using the spending method, one must sum the total value of all market transactions that occurred, including the sale of newly manufactured cars, the resale of vintage cars from a previous era, and the purchase of corporate stocks.

For each economic transaction listed, determine how it would be treated when measuring a country's total output by summing the total spending on all final goods and services for a given period.

Critique of the Spending-Based Output Measurement

To measure a country's total output for a specific year, an economist sums the total market value of all spending on final goods and services produced within that country. From the list below, which transaction would be included in this calculation?

In a given year, an economy has the following transactions: A car manufacturer produces 100 cars valued at $20,000 each and sells 90 of them to households. A local bakery produces and sells $50,000 worth of bread to consumers. A used car dealership sells a vintage car for $15,000. Using the method that measures an economy's total output by summing all spending on final goods and services, what is the total contribution of these transactions to the economy's output for the year?
