Document Summary
Alternative measures of inflation: to measure inflation for the whole economy, we need a way of. aggregating the many individual prices in the system. The basic idea is to come up with a statistic that is an appropriate weighted average of the individual prices in the economy. Then, inflation is measured as the percentage change in this statistic over time. Suppose we create a price index for student weekends when the typical student buys one large pizza for and three cokes for each in 2009. We will choose 2009 as our base year. Now suppose that the price of the large pizza rises to and the price of a coke rises to . 25 in 2010. Then the student weekend market basket will cost . 75. Also assume that the price of pizza in 2008 was . 50, and the cost of a coke was , so the market basket cost . 50 in 2008.
