Let's consider the effects of inflation in an economy comprising only two
people: Bob, a bean farmer, and Rita, a rice farmer. Bob and Rita both always
consume equal amounts of rice and beans. In year \(2015,\) the price of beans
was \(\$ 1,\) and the price of rice was \(\$ 3\)
a. Suppose that in 2016 the price of beans was \(\$ 2\) and the price of rice
was \(\$ 6 .\) What was inflation? Was Bob better off, worse off, or unaffected
by the changes in prices? What about Rita?
b. Now suppose that in 2016 the price of beans was \(\$ 2\) and the price of
rice was \(\$ 4 .\) What was inflation? Was Bob better off, worse off, or
unaffected by the changes in prices? What about Rita?
c. Finally, suppose that in 2016 the price of beans was \(\$ 2\) and the price
of rice was \(\$ 1.50 .\) What was inflation? Was Bob better off, worse off, or
unaffected by the changes in prices? What about Rita?
d. What matters more to Bob and Rita- -the overall inflation rate or the
relative price of rice and beans?
