To determine
Identify the values of gross investment,
Expert Solution & Answer
Explanation of Solution
The total amount of money spent on the new capital is gross investment. During the period of 2018, M has purchased $500,000 of new servers. Thus, the gross investment in 2018 is $500,000. At the same time, the market value of older servers falls by $100,000. This means that the depreciation of the older servers is $100,000. Since the gross investment is $500,000 and the depreciation is $100,000, the net investment is $400,000

- 1. In this question, assume all dollar units are real dollars in billions. For example, $100 means $100 billion. Argentina thinks it can find $105 of domestic investment projects with a marginal product of capital (MPK) equal to 10% (each $1 invested in year 0 pays off $0.10 in every later year). Assume a world real interest rate r*is 5%, and initial external wealth W (W in year -1) is 0. a. You find that the formula on the lecture slide: > r*, which means that a country will ΔΟ AK take on investment projects as long as the marginal product of capital (MPK) is at least as high as the real interest rate. Using this formula, answer if Argentina should conduct the project. b. If the projects are not done, GDP = Q = C = $200 in all years. Compute the present value of Q and C. c. If Argentina conducts the projects (investing $105), what is the present value of Q and C? d. If Argentina conducts the projects, what is the present value of C? Is Argentina better off with the investment?arrow_forward2. Consider a world of two countries: Highland (H) and Lowland (L). Each country has an average output of 9 and desires to smooth consumption.
