Inflation redistributes purchasing power among different groups in ways that can be both economically harmful and unjust; purchasing power keeps pace with inflation for some individuals, but not for others.

Inflation Effects

What are:a) Full indexationb) Partial indexation c) Fixed incomes

Full indexation: nominal income rises at the inflation rate

Partial indexation: nominal income rises at less than the inflation rate

Fixed incomes: nominal income stays constant

but expanding nominal incomes as well. The effect on households’ purchasing power

depends on which is greater- inflation or the increase in nominal income.

Inflation can also redistribute purchasing power between borrowers and lenders◦actual inflation > anticipated inflation Borrowers win◦actual inflation < anticipated inflation Lenders win◦actual inflation = anticipated inflation No one affected

Borrowing & Lending

Page 8: Ms. Park.  Amy  What’s the difference between CPI and GDP deflator?  What do you use when you want to calculate Real income? Real GDP?

Nominal interest rate: the interest rate expressed in money terms

Real interest rate: nominal interest rate – inflation rate

Inflation premium: % built into a nominal interest rate to anticipate the rate of inflation for the loan period

*Inflation premium = anticipated inflation

Desired real interest rate = Nominal interest rate - inflation premium

Nominal vs. Real interest rate

Page 9: Ms. Park.  Amy  What’s the difference between CPI and GDP deflator?  What do you use when you want to calculate Real income? Real GDP?

The nominal interest rate is 8%, the inflation premium on loans is 3%, and actual rate of inflation 5%.

What is the real interest rate? Find the difference between this rate and the desired real interest rate and explain how any difference affects borrowers and lenders.
