Question
Consider an economy that produces and consumes bread and automobiles. In the following table are data for two different years.
| 2010 | 2015 | |||
|---|---|---|---|---|
| Good | Quantity | Price | Quantity | Price |
| Automobiles | 100 | $50,000 | 120 | $60,000 |
| Bread | 500,000 | $10 | 400,000 | $20 |
Using 2010 as the base year, compute the following statistics for each year: nominal GDP, real GDP, the implicit price deflator for GDP, and a fixed weight price index such as the CPI.
| 2010 | 2015 | |
|---|---|---|
