5) Assume that after you graduate, you move to a simple economy in which only three
goods are produced and consumed: ish, fruit, and meat. Suppose that on January 1, ish
sold for $2.50 per pound, meat was $3.00 per pound, and fruit was $1.50 per pound. At the
end of the year, you discover that the catch was low and that ish prices had increased to
$5.00 per pound, but fruit prices stayed at $1.50 per pound, and meat prices had actually
fallen to $2.00. Can you say what happened to the overall CPI, in terms of whether it
increased, decreased, or stayed the same? Do you have enough information to calculate the
inlation rate? Note, this problem requires no calculation; just state and explain your
answers.
