President Kwame Nkrumah of Ghana had the Akesombo Dam built on the Volta River. It was expected that this large infrastructure project would help bring prosperity and growth to the people of Ghana. However, the project turned out to be unsuccessful, and didn't manage to bring Ghana on a path of stable, long-term growth. Which of these statements would Solow use to comment on this story? O The new infrastructure built in Ghana increased capital in the economy, thus leading to short-term negative growth. O The infrastructure brought new capital, but not new technology, which is essential for long-term growth. O The savings rate declined as an effect of the increase in capital, thus bringing Ghana to a lower steady state.

In the Solow growth model:1. Write the expression for consumption per capita in the steady-state equilibrium, asa function of capital per capita.2. What is the golden rule quantity of capital per capita ? Specifically, tell me thedefinition of this concept, and then relate it to the equation for the equilibriumconsumption per capita whose expression answers question (1) above.23. How do we find the golden rule savings rate, once we know the golden rule quantityof capital per capita?
Consider the Solow Model with no population or technological growth. Suppose that two countriesare identical except that in Country A the depreciation rate is greater than the depreciation rate inCountry B.a. How do you compare the steady state level of capital per worker in these countries? Illustrategraphically. Explain the economic intuition for the di erences in capital per worker in steadystate.b. Which country a higher output per worker in steady state? What about investment per workerin steady state? Explain carefully.
Is it possible to have economic growth with no opportunity cost? A)Yes, economic growth requires no current sacrifices-only the passage of time. B) No, but economic growth is always worth whatever sacrifice is required. C) No, because growth depletes the stock of knowledge so that more growth today means less growth tomorrow D) No, because growth requires the sacrifice of consumption goods in order to invest in such things as capital tormation and research and development.
If in 2008 China’s real GDP is growing at 9 percent a year, its population is growing at 1 percent a year, and these growth rates continue, in what year will China’s real GDP per person be twice what it is in 2008 Please use the other formula to solve this proble not the rule of 70, because i have the solution using rule 70!

In 1998, Brazil had a per capita GDP of about $4,500, compared to per capita GDP of about $28,000 in the US. (A) If per capita growth were to average 2% per year indefinitely in the US and 5% per year in Brazil, how many years would it take Brazil to catch up with the US? (B) Using the assumptions of the Cobb-Douglas production function, how fast would capital stock have to grow for per capita GDP to rise 5% per year? How does that compare with capital stock growth of 3% per year in the US (assume technology advances 1% per year in both countries)? (C) In mature industrialized societies, the capital/output ratio is approximately 3.0. If the average depreciation rate is 0.04, what would be the current saving and investment ratio in the US? What would it be in Brazil if per capita GDP rose 5% per year?
. Suppose that society decided to reduce consumptionand increase investment.a. How would this change affect economic growth?b. What groups in society would benefit from thischange? What groups might be hurt?
Suppose that there are diminishing returns to capital. Suppose also that two countries are the same except one has more physical capital per worker and so it has more real GDP per worker than the other. Finally, suppose that the saving rate in both countries increases from 5 percent to 7 percent. In the long run we would expect that a. the growth rate will not change in either country. b. the country that started with less physical capital per worker will grow faster. c. the country that started with more physical capital per worker will grow faster. d. both countries will grow and at the same rate.
Suppose that 10 workers were required in 2010 to produce 40,000 bushels of wheat on a 1,000-acre farm. a. What is the average output per acre? Per worker? b. If in 2020 only 8 workers produce 44,000 bushels of wheat on that same 1,000-acre farm, what will be the average output per acre? Per worker? c. By what percentage does productivity (output per worker) increase over those 10 years? Over those 10 years, what is the average annual percentage increase in productivity?
