The following is related to your previous study guide:
Nominal interest rate = rate stated on loan agreement
Assume I loan you $100 at a rate of 6 percent, and that the inflation rate is
6 percent. How much of an increase in purchasing power do I obtain when you
pay me back? Consequently, what is the real rate of interest on this loan?
Develop an equation that contains the real rate of interest, the nominal rate
of interest, and the rate of inflation.
Problems of inflation:
When unexpected, inflation hurts (borrowers or lenders). In this way
unanticipated inflation redistributes real income from whom to whom?
Inflation makes business planning more difficult.
Inflation hurts those on fixed incomes.
_____________________________________
Tradeoff between inflation and unemployment:
To reduce inflation, government can enact policy to reduce aggregate demand.
But with less spending in the economy, output is expected to drop and
unemployment is expected to rise.
To reduce unemployment and increase output, government can enact policy to
increase aggregate demand. But with more spending, there will be upward
pressure on prices.
So, the NAIRU policy objective is to adjust the level of aggregate demand in
order to lower unemployment as much as possible without causing inflation to
take off.
Implication: It is the goal of government policy to have some cyclical
unemployment! (Explain.)

this difference matter?
