Consumers of the economy purchase all primary products, manufacturing products and services shown in the table. Manufacturing products and services are all produced by the domestic economy. However, for each year, 3/4 of the primary products is imported, and 1/4 is produced domestically. Set 1973 as the base year.Find the % change in prices for primary products, manufacturing products and services, respectively, from 1973 to 1974.
Find the CPI for both years. Calculate the corresponding inflation rate from 1973 to 1974.
Find the nominal and real GDP for both years. Hence, find the GDP deflator for both years. Calculate the corresponding inflation rate from 1973 to 1974.
The above table is set up in such a way to mimic the actual data of the inflation rates calculated from the CPI and the GDP deflator, respectively, for the US during the first oil crisis in 1973- 1974. Use your results to explain how and why the two numbers differ by such a wide margin during that period.
The "pizza connection" refers to the observation that in a major city, the cost of a slice of pizza is always about the same as the subway fare. Using the CPI values from the table
shown below and the CPI table, determine what a slice of pizza should have cost in 2009 if it cost $1.00 in 1984 and prices had risen with the CPI. What does this tell you about how
actual pizza prices changed compared to the CPI?
