Document Summary

The individual marginal willingness-to-pay for a public good is given below: P = 10 q, where q is the public good. Assume that there are 100 identical individuals in a community. Tax-price paid by each individual for each unit of public good = . Total net benefit for each individual = . The individual marginal willingness-to-pay for a private good is given below: P = 10 q1, where q1 is the quantity demanded by one individual. Assume that there are 100 identical buyers in the market. Aggregate quantity bought and sold is symbolized as q. The abatement cost function of polluting plants is given below: Total damage cost function is tdc = 2e2. Marginal damage cost function is mdc = 4e. 20 = e + a max e = 20 max a = 20. A = units of abatement (reduction) of emissions. Tdc when e is at max = (20)/2 = . Total damage costs (tdc) = (4)/2 = .

Suppose the market demand curve for a good is represented by the linear equation Q = 60 - 0.75P. If the market price were to increase from P = $20 to P = $40, then holding all other factors constant:

the quantity demanded would decrease by 10 units and total expenditures on the good would decrease by $400

the quantity demanded would decrease by 15 units and total expenditures on the good would increase by $300

the quantity demanded would decrease by 30 units and total expenditures on the good would increase by $1200

the quantity demanded would increase by 20 units and total expenditures on the good would decrease by $800

the quantity demanded would increase by 10 units and total expenditures on the good would increase by $100

the quantity demanded would increase by 25 units and total expenditures on the good would increase by $1000

A perfectly competitive firms supply curve for a good identifies the:
i. minimum quantity supplied at each price, holding all other factors constant
ii. firms minimum willingness to accept for each incremental unit of the good (e.g., the first unit, second unit, etc.), holding all other factors constant
iii. maximum quantity supplied at each price, holding all other factors constant
iv. firms maximum willingness to accept for each incremental unit of the good (e.g., the first unit, second unit, etc.), holding all other factors constant

Considering the supply side of a market for a good, if a firms supply curve were vertical, then:

the law of supply holds, and quantity supplied is completely insensitive to changes in price

the law of supply holds, and quantity supplied is highly sensitive to changes in price

the law of supply fails to hold, and quantity supplied is completely insensitive to changes in price

the law of supply fails to hold, and quantity supplied is highly sensitive to changes in price

none of the above

The determinants of supply are:
i. factors other than price that will affect the quantity of a good or service a firm is willing and able to purchase
ii. factors that affect a producers maximum willingness-to-accept to produce various quantities of a good
iii. factors that affect a producers minimum willingness-to-accept to produce various quantities of a good

Suppose a market has two identical sellers. If each sellers supply function is given by P = 20 + Q, then the market supply function is:

From the market framework discussed in class and the readings, it may be concluded that in order for a good to be exchanged between a seller and a buyer, it must be that:

buyer maximum willingness-to-pay is greater than seller minimum willingness-to-accept

buyer maximum willingness-to-pay is greater than or equal to seller minimum willingness-to-accept

buyer minimum willingness-to-pay is greater than or equal to seller maximum willingness-to-accept

buyer minimum willingness-to-pay is greater than seller maximum willingness-to-accept

If the market demand function is given by P = 80 - 0.3Q and the market supply is given by P = 20 + 0.1Q, then the equilibrium price and quantity are:

Of concern are the affects of sustained summer droughts on the domestic supply of wheat. Noting that wheat is a primary ingredient in the production of bread and that potatoes are a substitute for bread, if the supply of wheat declines then it is reasonable to expect:

the price of wheat to fall, the supply of bread to increase, and the demand for potatoes to increase

the price of wheat to fall, the supply of bread to increase, and the demand for potatoes to decrease

the price of wheat to rise, the supply of bread to decrease, and the demand for potatoes to decrease

the price of wheat to rise, the supply of bread to decrease, and the demand for potatoes to increase

the price of wheat to rise, the supply of bread to increase, and the demand for potatoes to increase

the price of wheat to rise, the supply of bread to increase, and the demand for potatoes to decrease

Suppose a perfectly competitive market is initially in equilibrium. If market demand and supply decrease simultaneously, then equilibrium:

price will rise, but the equilibrium quantity may either rise, fall, or remain unchanged

quantity will rise, but the equilibrium price may either rise, fall, or remain unchanged

price will fall, but the equilibrium quantity may either rise, fall, or remain unchanged

quantity will fall, but the equilibrium price may either rise, fall, or remain unchanged

Considering the demand side of a market for a good, the consumer surplus derived by an individual:
i. is the difference between the maximum amount the consumer is willing to pay on each unit and the minimum prices that producers are willing to accept
ii. is the difference between the minimum amount the consumer is willing to pay on each unit and the price he/she
actually pays
iii. is the difference between the maximum amount the consumer is willing to pay on each unit and the price he/she actually pays
iv. will decrease if price increases

Suppose the market demand for a good is described by the equation P = 120 - 2Q. If a change in market supply results in price decreasing from P0 = $80 to P1 = $70, then the resulting change in consumer surplus is:

2.) Consider a beekeeper that is deciding how much honey to produce. The beekeeper gains a benefit from producing honey, represented by the marginal benefit function and which is given by:

MB= 300 - 6Q

where Q is barrels of honey.

In addition, she has a marginal cost function, which reflects her cost of producing honey; this is given by:

MC= 40 + 4Q

The beekeeperâs total profit function is given by:

Profit= 360Q + Q^2

The more honey the beekeeper produces, the more bees there are to pollinate a neighboring apple orchard. Thus, in addition to the private benefit accruing to the beekeeper herself, there is also a marginal external benefit to the apple orchard, which is given by:

MEB= 100 - 2Q

And a total external benefit to the apple orchard given by:

TEB= 100Q - Q^2

a. Find an expression for the social marginal benefit (SMB) in this case, defined as you think appropriate. Calculate the level of honey production that will arise if the beekeeper acts in her self-interest only. Calculate the socially efficient level of honey production as well.

b. Suppose that the beekeeper and the owner of the apple orchard enter into negotiations. The orchard owner wants to offer a payment to the beekeeper to change honey production from her self-interested production level to the socially efficient level (all at once). What is the maximum total payment that the orchard owner would be willing to pay for this overall change? What is the minimum total payment that the beekeeper would require before making this overall change?

c. Assume that, if a deal is reached, each party must pay $35 in legal fees to finalize it. If there are no additional transaction costs, will the socially efficient quantity be reached? Explain.

d. Irrespective of your answer to part c, assume that the beekeeper and the orchard owner come to a private agreement to set honey production at the socially efficient quantity. However, now suppose that a policymaker reads somewhere that honey production provides a positive externality to apple orchards, and therefore decides that the beekeeper should be provided with a production subsidy for each unit of honey that the beekeeper is willing to produce. With this subsidy in place, the beekeeper decides to increase production by an additional 5 barrels. Calculate the associated efficiency loss.

e. If honey is good to eat and bees are good for trees, why is there such a thing as too much honey?
