Document Summary

Two ways of measuring price indices: market-based price indices: cpi, ppp, nipa-based price indices: gdp implicit deflator, pce index. (nominal gdp divided by real gdp) x 100. If the nominal gdp is bigger than real, it"s because prices are higher in current year than they were in real change dollars. In the base year, the price index is always = 100 in this case, 2009 is the base year. [(deflator in 2010-deflator in 2009)/(deflator in 2009)]x100 = 1. 21% When you"re reading the deflator the year after the base year (in this case, base year is 2009), you know what the inflation rate is even without doing the math. The fed prefers to use pce instead of cpi. (personal consumption expenditures)/(chained personal consumption expenditures) x 100. Compute the inflation rate: ((nominal pce-real pce)/real)x100 ((110. 72-109. 54)/109. 54)x100 = 1. 08% During a recession, the inflation rate goes up. Cpi (consumer price index) is much more volatile (goes up and down a lot more)

3. Indian GDP in 2010 was 78.9 trillion rupees, while U.S. GDP was $14.5 trillion. The exchange rate in 2010 was 45.7 rupees per dollar. India turns out to have lower prices than the United States (this is true more generally for poor countries): the price level in India (converted to dollars) divided by the price level in the United States was 0.368 in 2010.
(a) What is the ratio of Indian GDP to U.S. GDP if we donât take into account the differences in relative prices and simply use the exchange rate to make the conversion?
(b) What is the ratio of real GDP in India to real GDP in the United States in common prices?
