    1. President DT of the United States has forwarded a bill to congress proposing a $5 per Kg
    tax on oranges imported from Mexico. The purpose of the policy is to secure funds for
    financing the construction of a $500 million border wall between the US and Mexico.
    The Supply of Mexican oranges imported to the US: Q S = 3p, where p is the price per Kg
    and Q is the quantity supplied (in million Kg). The Demand for oranges from the US
    consumers is Q D = 100 - 2p, where p is the price per Kg and Q is the quantity demanded
    (in million Kg).
    (a) What effect will this policy have on market price and how will that affect US
    consumers of orange?
    (b) If this is the only way to secure funds for the construction of the wall, will President
    DT be able to realize this electoral promise? Explain using figures from your
    calculation.
    (c) What percentage of the burden of the tax will be borne by Mexican orange farmers?

    2. Suppose the market for corn in Canada is represented by the following equations for
    supply and demand:
    Q S = 2p − 2
    Q D = 13 − p
    where Q is the quantity in millions of bushels per year and p is the price.
    (a) Calculate the equilibrium price and quantity.
    (b) Using price elasticity of demand, what will be the effect of a 4% increase in price on
    quantity demanded?
    (c) If the government imposes a price floor at $7 per bushel, will there be a surplus or a
    shortage and how much will this cost the government? Draw a graph to show this.

    3. The annual accounting statement of revenues and costs for a local flower shop shows the
    following:
    Revenues  $250,000
    Supplies  $25,000
    Employee Salaries  $170,000
    If the owners of the firm closed its operations, they could rent out the land for $100,000.
    They would then avoid incurring any of the expenses for employees and supplies.
    (a) Calculate the shop’s accounting profit and its economic profit.
    (b) Would the owners be better off operating the shop or shutting it down? Explain.

    4. Jeremy derives all of his utility from consuming milk shakes; he devotes his entire $20
    allowance to milk shakes each week. Suppose the price of milk shakes rise from $2 to $4.
    Compute Jeremy's Compensating Variation and Equivalent Variation.

    5. The bolt-making industry in Ontario currently consists of 20 producers, all of whom
    operate with the identical short-run total cost curve STC(Q) = 16 + Q 2 , where Q is the
    annual output of a firm. The market demand curve for bolts is D(P) = 110 – P, where P is
    the market price.
    (a) Assuming that all of each firm’s $16 fixed cost is sunk, what is a firm’s short-run
    supply curve?
    (b) What is the short-run market supply curve?
    (c) Determine the short-run equilibrium price and quantity in this industry.

    6. The firm’s production function is q(K, L) = L β K α , . Let α = 2/3 and β = 1/3. The wage
    rate is $4 and the rental rate of capital is $27.
    (a) What is the marginal rate of technical substitution of labour for capital (MRTS LK )?
    (b) Suppose that the firm wishes to produce 1080 units of the good, what is the lowest
    cost at which it can produce this quantity?
    (c) What is the amount of capital and labour used at the cost minimization bundle?
    (d) Suppose that the price of capital increases, so that now r = $64. The firms still wishes
    to produce 1080 units. What is the new cost minimization bundle on inputs for this
    firm, and total cost, for this firm?
    (10 Marks)
    7. A firm’s total cost function is given by the equation:
    TC = 4000 + 5Q + 10Q 2
    (a)Write an expression for each of the following cost concepts:
    (i)Total Fixed Cost
    (ii)Average Fixed Cost
    (iii)Total Variable Cost
    (iv)Average Variable Cost
    (v)Average Total Cost
    (vi)Marginal Cost
    (b) Determine the quantity that minimizes average total cost.
    (c) Demonstrate that the relationship between marginal cost and average cost holds.
