The world comprises two countries, A and B. There is only one good, whose price is normalized to 1; hence nominal and real measures coincide. These two countries differ with respect to their production technology. In particular, MPKA = 10 - 0.8KA and MPKB = 7 - 0.7KB , where MPKi denotes the marginal product of capital and Ki the capital stock in country i = Α, Β.The total capital stock in the world is 10 units.
a) The initial allocation of capital is KA=5 and KB=5. Find each country’s total income as well as labor and capital income. What is the world income?
b) Next, consider the case where there is free capital mobility. Find the capital allocation between the two countries, each country’s total income, as well as labor and capital income. What happens to world income? Explain your answers.
c) Assume now that, succumbing to domestic pressure, the government of country A imposes a 30% tax on capital income. Show graphically the equilibria before and after taxation. Find the new capital allocation between the two countries, total income, tax revenue, as well as labor and net capital income in each country. Explain your answers.
Note: Round your answers to the second decimal point.
eplaination
of part b) capital is not equally productive in the both countries.
hence if capital moves from a less productive country to a high
productive country untill their marginal products match then it
will result in increasing both countries income as well as world
income.
I hope this answer helped you. If you need more explainations let me know in the comments so that i can edit or comment wit more explainations. give good feedback . wish you a great day ahead

Consider the world with two countries: Country A and Country B. There are two states of the world: State 1 and State 2, and the probability of realization of each state is 50%. In State 1, output of Country A is $100 billion, and output of Country B is $80 billion. In State 2, output of Country A is $90 billion, and output of Country B is $120 billion. Assume that the share of labor income in output is 60%...

Consider a world with two countries, Home and Foreign, both able to produce two goods: cloth and tablet computers. The production of both goods uses capital and labor in fixed proportions, with the tablets industry using more capital per worker than the cloth industry. The units of each input needed to produce one unit output are given by: capital Labor Cloth 1 2 Tablets 2 1 Both countries have 150 units of capital available for production, but the Home country...

Consider two countries, Spain and Italy, where the only two factors of production are capital and labor. Spain has 100 units of capital and 400 units of labor and Italy has 200 units of capital and 100 units of labor. Both countries produce two goods, cheese and suits. The labor share in total production costs is 75% for cheese but only 25% for suits. (2 points for each part) A. Which country is labor abundant? Explain. B. Which good is...

Assume a world of two goods, beef and cars; and two countries South Africa and Botswana. Cars are capital intensive and Botswana is labour abundant. Assume the standard H-O assumptions hold. According to the Rybczynski theory, if labour doubles in Botswana how does production and consumption compare to pre-growth conditions in Botswana? Explain with the relevant diagram. b. CMU is a country that produces apples and computers, where computers are capital intensive; CMU’s PPF is bowed out (exhibits increasing relative...
