Answer to Question #144178 in Macroeconomics for elena

Question

Samantha deposits $2,000 in a saving account that pays an annual interest rate of 3 percent. Though the expected inflation was 2%, over the course of the year the inflation rate is 4 percent. Calculate how much money Samantha has at the end of the year and how much her purchasing power has changed.

Answer 1

Amount at the end of the year = 2000 + 3$/$ 100 $\times$ 2000

= 2000 + 60

= $\$$ 2060

Purchasing power when inflation rate was 2 $\%$

= 2060-2$\%$

= $\$$ 2018.8

Purchasing power when inflation rate actually was 4 $\%$

= 2060-4$\%$

=$\$$ 1977.6

Hence as the result of the rise in the actual rate of inflation , the purchasing power dropped by $\$$ 41.2
