While the details of the chapter are not given, I am listing the
following reasons why in general it is hard to have contracts in
real terms than nominal terms-
- Nominal terms contracts are easy to make, track and understand
for everyone. It is obviously easy to have a contract that gives a
raise of lets say 10% a year in nominal terms. For real terms one
must first see inflation each year and then adjust everything
accordingly.
- Uncertainty- When making a contract in nominal terms, one is
certain how much they are going to get year after year. Real terms
are based on inflation, which will only be measured once the year
ends, and hence add uncertainty into everything.
- Real terms have different meaning for everyone- Based on my
consumption, inflation might be different for me. For example, if I
have a big family and a big chunk of my salary is spent on foods,
then my inflation would be very different from a person who is
single and spends mostly on electronics. Food inflation and
electronics inflation will be different every year. So we will
actually end up having our salary grow at different rates.
