3. In the year 1999, you remember your dad telling you “boy, when I was your age, I
made $1.50 per hour. You don’t know how good you got it.” The reason for this
heart-to-heart is that in 1999, you earned $6.00 per hour and complained about
how low your pay was.
Clearly, your dad is confusing nominal and real values. When your dad was your
age, it was 1969 and the CPI was 36.7. In 1999, the CPI was 166.1 Tell your dad
what the 1999 real equivalent of his wage was. Did he really make less than you?
4. Suppose Country A is able to sustain an economic growth rate of 3% a
year and Country B is able to sustain an economic growth rate of 1% a
year.
a. How long will it take for income to double in each country?
b. Another way to look at the effect of growth rates on income is to use the
concept of compound interest. The formula for compound interest is:
? ?t F ? P? 1? r
P is the starting amount, F is the future amount, r is the growth rate, and t
is the number of years the economy has been growing for at that particular
growth rate. Note: enter in the growth rate in decimal form. That is, if
the growth rate is 3%, then r=0.03.
Suppose Country A and Country B both start with income equal to $100.
At their respective growth rates, what will income be in each country after
25 years? 75 years? 200 years? What does tell you about where income
inequality between countries comes from?
c. Suppose you are elected Prime Minister of Country B. Propose two
policies that would help Country B increase its growth rate? Explain why
your policies will promote economic growth.
