1)The table above has the market demand schedule in an industry that has two firms in it. The marginal cost of this product is zero because these two firms have exclusive ownership of the resource and it does not cost any additional amount to produce additional units.

A)If the firms cooperate with each other so that they operate as a monopoly, what price will they charge and what (total) output will they produce? (4%)

B)If the firms cannot cooperate but instead behave as perfect competitors, what will be the price and the (total) output they produce? (4%)

Answer:

A)As a monopoly, the price will be $15 and the total output will be 30 units. This price and output combination is where they maximize their total profit because it is here that the marginal revenue equals zero. (The marginal revenue equals zero because this is the price and output combination for which total revenue is maximized and marginal revenue equals zero when total revenue is maximized.)

B)The perfectly competitive price is equal to marginal cost. Because marginal cost is equal to zero,the price will be $0 and the output will be 60 units.

2)Consider an economy produced 100 apples and 50 oranges in year 1. The price of apple is $2 and the price of orange is $5. In year 2, the production of apples is 120 and oranges decreased by 10%. The price of the apples is $3 and the price of oranges is $6.

A)Calculate the nominal GDP in year 1 and 2. (4%)

B)Use year 2 as based year, calculate the CPI in year 1 and 2. (3%)

C)What is the inflation rate from year 1 to year 2? What is the inflation rate if we use year 1 as based year? (4%)

Answer:

A)Nominal GDP in year 1: 100(2)+50(5)=450; Nominal GDP in year 2: 120(3)+45(6)=630

B)CPI in year 1: [120(2)+45(5)]/[120(3)+45(6)](100)=73.80; CPI in year 2: 100

C)Inflation: (100-73.80)/73.80=35.48%; Inflation (base year: 1): [100(3)+50(6)]/450-1=33.33%

3)Consider an economy with the price of apple is $5 and the price of orange is $10. John, with $100 in his pocket, is making the decision on how to spend this $100.
