Question 4

Question 6
The government of a country decides to implement a policy of price control to combat inflation. However, the policy leads to a shortage of essential goods. Which of the following is a likely consequence of this policy?
Question 7
A firm is considering investing in a new project with the following cash flows: Year 0: -₦100,000, Year 1: ₦50,000, Year 2: ₦75,000, Year 3: ₦100,000. If the firm's \cost of capital is 10%, what is the present value of the project?
Question 8
A firm produces two goods, A and B, u\sing two inputs, labor and capital. The production function for good A is given by Q_A = 2L^0.5K^0.5, where Q_A is the quantity of good A produced, L is the amount of labor used, and K is the amount of capital used. The production function for good B is given by Q_B = 3L^0.2K^0.8. If the firm has 100 units of labor and 200 units of capital, how much of good A should it produce?
Question 9
Consider a firm that produces a \single good u\sing two inputs, labor (L) and capital (K). The production function is given by Q = 2L^0.5K^0.5. If the firm's current input prices are w = ₦100 and r = ₦150, and it currently employs 4 units of labor and 9 units of capital, calculate the firm's current total \cost.
Question 10
A government is considering a tax on a particular good to raise revenue. The demand function for the good is given by Q = 100 - 2P, and the supply function is given by Q = 2P - 10. If the government wants to raise revenue of ₦10,000,000, what is the optimal tax rate?
Question 11
A consumer's indifference curve is represented by the equation u(x, y) = 2x + 3y. If the consumer's income is ₦100 and the prices of x and y are ₦5 and ₦3 respectively, what is the consumer's optimal bundle?
Question 12
A firm is operating under a perfectly competitive market structure. If the firm's marginal revenue is 100 and the price of the product is 120, what is the firm's marginal \cost?
Question 13
Consider a firm that produces two goods, X and Y, u\sing two inputs, labor (L) and capital (K). The production functions are given by Qx = 2L^0.5K^0.5 and Qy = 3L^0.5K^0.5. If the firm's current input prices are w = ₦100 and r = ₦150, and it currently employs 4 units of labor and 9 units of capital, calculate the firm's current total \cost.
Question 14
A country's balance of payments is given by the following accounts: Current Account: ₦100,000,000; Capital Account: ₦50,000,000; Financial Account: ₦20,000,000. What is the country's net foreign exchange earnings?
Question 15
A country's balance of payments can be affected by the following factors: (i) a decrease in the price of its exports, (ii) an increase in the price of its imports, (iii) a decrease in the price of its imports, and (iv) an increase in the price of its exports. Which of the following would lead to an improvement in the balance of payments?
