Answer to Problem 1KC

Option 'd' is correct.

Explanation of Solution

The economic growth is the increase in the inflation adjusted market value of goods and services in the economy over a time period. The main element that helps to the economic growth is the consumption of the goods and the services by the consumers. The consumption is done on the basis of the disposable income of the consumers and the relation between the consumption and the disposable income of the consumers is known as the consumption function.

Option (d):

When there is a change in the disposable income of households, there will be changes in the consumption pattern of a consumer. When the disposable income increases, it increases the quantity demanded and when the disposable income decreases, it decreases the quantity demanded. This means that there will be a movement along the same consumption function and there will be no shift in the consumption function. Hence, option 'd' is correct.

Option (a):

For example, when the real assets change for a consumer, the real value of money for a consumer also changes. When there is an increase, it increases the money balance of a consumer which helps him to consume more than what he was able to consume in the previous period and vice versa when the real asset value decreases. Therefore, there will be a shift in the consumption function and option 'a' is incorrect.

Option (b):

The interest rate determines the consumption function of an individual. When the rate of interest is higher, consumers will consume less and save more and vice versa. Thus, the changes in the interest rate of the economy shift the consumption function. Hence, option 'b' is incorrect.

Option (c):

The expectations of the price change are an important factor that leads to the shift in the consumption function. The decrease in the price level increases the real balances of the consumer, whereas the increases in the price level decreases the real balances that cause the shift in the consumption function. Hence, option 'c' is also incorrect.

Option (e):

The taxation determines the income of consumers. When the tax rate is decreased, it increases the income of consumers and vice versa when the tax is increased. Hence, the changes in the taxation policies lead to the shift in the consumption function and option 'e' is incorrect.

6. Rent seeking The following graph shows the demand, marginal revenue, and marginal cost curves for a single-price monopolist that produces a drug that helps relieve arthritis pain. Place the grey point (star symbol) in the appropriate location on the graph to indicate the monopoly outcome such that the dashed lines reveal the profit-maximizing price and quantity of a single-price monopolist. Then, use the green rectangle (triangle symbols) to show the profits earned by the monopolist. 18 200 20 16 16 14 PRICE (Dollars per dose) 12 10 10 8 4 2 MC = ATC MR Demand 0 0 5 10 15 20 25 30 35 40 45 50 QUANTITY (Millions of doses per year) Monopoly Outcome Monopoly Profits Suppose that should the patent on this particular drug expire, the market would become perfectly competitive, with new firms immediately entering the market with essentially identical products.

Consider a call option on a stock that does not pay dividends. The stock price is $100 per share, and the risk-free interest rate is 10%. The call strike is $100 (at the money). The stock moves randomly with u=2 and d=0.5. 1. Write the system of equations to replicate the option using A shares and B bonds. 2. Solve the system of equations and determine the number of shares and the number of bonds needed to replicate the option. Show your answer with 4 decimal places (x.xxxx); do not round intermediate calculations. This is easy to do in Excel. A = B = 3. Use A shares and B bonds from the prior question to calculate the premium on the option. Again, do not round intermediate calculations and show your answer with 4 decimal places. Call premium =
