power was in violation of the Sherman Act.

8) A breakdown of the shares of economic production for two different countries is
listed below, along with per capita income and growth rate. Use this information to
calculate the growth rates per sector and answer the following questions.
(a)What is the amount of per capita growth in countries A and B? Will the growth
increase, decrease or maintain the income gap?
(b)Suppose country As economy becomes more industrialized, increasing the
productive share of services and industry. What likely effect will this having on country
As growth rate? Suppose as a result of this change the growth rate of services and
industry is now 3.5% and 2.5% respectively, while the rates for natural resources and
agriculture remain the same. What is the new total growth rate? What is the new
distribution of the economy? What is the effect of the new growth on the income gap?
(c)What growth rate would country A have to maintain to reduce the income gap with
country B by 10%, assuming country B grew by 5%? If country B grew by 2%? If
country B experienced no growth?
(d)What growth rate would country A have to maintain to reduce the income gap with
country B completely if country B experienced 3% growth?
(e)What do your answers in (a) through (d) tell you about the situation facing
developing countries? How does the element of time (growth over several years)
change your answer?
