In: Economics
Assume that a typical consumer's basket consists of 10 lbs of beef and 20 lbs of chicken. also assume that 2011 is used as the base year in the CPI calculation. Use the data below to answer the following two questions.
a. Calculate the CPI in years 2010, 2011, and 2012
b. Calculate the inflation rate between 2010 and 2011 and between 2011 and 2012.

a. Calculate the CPI in years 2010, 2011, and 2012
CPI in 2010
Value of basket = (10 x 4) + (20 x 4) = $120
--
CPI in 2011
Value of basket = (10 x 5) + (20 x 5) = $150
(This is the base year)
--
CPI in 2012
Value of basket = (10 x 9) + (20 x 6) = $210
----
b. Calculate the inflation rate between 2010 and 2011 and between 2011 and 2012.
Inflation is the rate of change of CPI.
Between 2010 and 2011,
Inflation =
= 25%
---
Between 2011 and 2012,
Inflation =
= 40%
