good afternoon i would like some assistance with the following

1. Latin American and Caribbean citizens who migrate to the United States earn salaries there that are higher than what they were earning at home. Since the migrants have the same skills as when they lived in Jamaica, why are they apparently more productive in their new country? 2. The youth wing of the African National Congress in South Africa has called for the nationalization (take over of ownership by the government) of that country's mines and banks. What will be the effect on investment? On economic growth? Explain why for each answer. 3. China's economy has been growing at the breakneck pace of around 8 percent per year for the last 15 years as a result of an institutional change - its decision in 1990 to open up to trade with the rest of the world. Make a prediction about China's rate of growth over the next decade and defend your prediction. 4. What is a production function? Draw one and explain what it is illustrating. 5. Determine whether each of the following is represented by a movement along or a shift of the production function (against capital) and illustrate each on a production function graph. (Hint: Is the change in output that is caused by each event due to a change in the stock of capital or to change in the productivity of an unchanged capital stock?) a) GraceKennedy invests $125 million in a new manufacturing plant. b) A new highway linking two major towns is constructed. c) A new fertilizer formula improves crop yields. d) An earthquake. e) Illegal drug traffickers start to bribe judges and corrupt the justice system. 6. If GDP is $500, the capital stock is $150, the savings rate is 20%, and the rate of capital depreciation is 10%, by how much will the capital stock expand next period? Do you expect output to rise or fall
