Expert Solution & Answer
Answer to Problem 1CQQ
Option ‘b’ is the correct answer.
Explanation of Solution
Option (b):
A change in
Option (a):
Hot dogs can be considered as substitutes of hamburgers. A change in the price of a substitute good shifts the demand curve of a good. Thus, a change in price of hot dogs shifts the demand curve of hamburgers. So, option ‘a’ is incorrect.
Option (c):
Hamburger buns can be considered as complementary goods of hamburgers. A change in the price of a complementary good shifts the demand curve of a good. Thus, a change in the price of hamburger buns shifts the demand curve of a hamburger. So, option ‘c’ is incorrect.
Option (d):
A change in the income of a consumer of a good shifts the demand curve of that good. Thus, a change in the income of hamburger consumers shifts the demand curve of hamburger. So, option ‘d’ is incorrect.
Economics Concept Introduction
Concept introduction:
Complementary good: It is a good with a negative cross
Substitute good: It is a good with a positive cross elasticity of demand, that is, a good whose demand is decreased when the price of another good is decreased.

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?
