Question： What is the GDP deflator ? Please teach us the way to analyze GDP deflator. Nominal GDP The production of goods and services valued at current prices. Real GDP The production of goods and services valued at constant prices. GDP deflator: The GDP deflator is the ratio of nominal GDP to real GDP times 100. GDP Deflator The GDP deflator is calculated as follows: The nominal GDP of a given year is computed using that years prices. The real GDP of that year is computed using the base years prices. Economists and policymakers monitor both the GDP deflator and the consumer price index to gauge how quickly prices are rising.

Using 2005 as the base year，calculate the real GDP for each year C. Please calculate the GDP deflator for each year 2005: $10 x 400 + $2 x 1000 = $6,000 2006: $11 x 500 + $2.50 x 1100=$8,250 2007: $12 x 600 + $3 x 1200= $10,800 Pizza Coffee Years P Q P Q 2005 $10 400 $2.00 1000 2006 $11 500 $2.50 1100 2007 $12 600 $3.00 1200 2005: $10 x 400 + $2 x 1000 = $6,000 2006: $10 x 500 + $2 x 1100 = $7,200 2007: $10 x 600 + $2 x 1200 = $8,400 C.

Suggestion: Ask your students to compute nominal GDP in each year before revealing the answers. Ask them to compute the rate of increase before revealing the answers. In this example, nominal GDP grows for two reasons: prices are rising, and the economy is producing a larger quantity of goods. Thinking of nom
