If the government implements a $5 per-unit subsidy,
payable to the buyer
, what is the
marginal cost of the unit number 102?
Round to two decimal places and do not enter a currency symbol. If your answer is
$1.125, enter 1.13.

Correct Answer
119
The supply schedule gives marginal cost. That is, the marginal cost of the unit
101 is the price at which 101 units is supplied.
A tax payable by the seller increases the marginal cost by an amount equal to
the tax, whereas a subsidy paid to the seller decreases the marginal cost by
an amount equal to the subsidy.
Neither a tax payable by the buyer nor a subsidy payable to the buyer affects
the marginal cost incurred by the seller.
Assume assumption BIG holds.
Prof. Gazzale is selling one quiz drop for $21. It costs Prof. Gazzale $13 to record and
process a quiz drop. Suchi is willing to pay up to $34 for the quiz drop, and Ishrak is
willing to pay up to to $42.
If the quiz drop is efficiently allocated, how much surplus is created?
Round to two digits, and do not enter the currency symbol. If your answer is -$1.275,
enter -1.28.

If efficiently allocated, it goes to whomever has the highest WTP. Surplus is
thus that person's WTP minus MC.
Prof. G. is selling a quiz drop for a good cause!
He incurs a time cost of $19.00 to record and process a quiz drop. Each of two student
submits a bid, the amount of money the student will pay if awarded the quiz drop. The
student submitting the highest bid receives the quiz drop and sends this amount to
Indspire, a charity helping Indigenous students in Canada complete their university
education. In addition, Prof. G. will send $38.00 to Indspire.
Suchi, who would pay up to $57 for an extra quiz drop, bids $43.50. Ishrak, who would
pay up to $70 for an extra quiz drop, bids $45.00.
If these are the only two bidders, how much surplus has been created?
Round your answer to two decimal places, and do not enter the currency symbol. If
your answer is -$1.275, enter -1.28.

If the demand of the condominiums demand is inelastic, that is, it is a normal good, and when the price of the condominiums will decrease, then the demand of the people for the product will increase because the consumer surplus will exist when the money spent by the people will be more as compared to the price which is to be charged for the product. As the price will decrease, the people will prefer to buy more because it is already a normal good and demand for more. Pertaining to the supply of Condominiums in response to the demand of Nagenyos, enumerate at least two (2) possible effects of the determinants of demand (a) price, (b) income, (c) prices of related goods like apartments and residential houses, and (d) consumer taste and expectation, and the determinants of supply (a) flexibility of inputs, (b) mobility of inputs, (c) ability to produce substitute and (d) time.

In recent years, the government of Pakistan has established a support price for wheat of about $0.20 per kilogram of wheat. At this price, consumers are willing to purchase 10 billion kilograms of wheat per year, while Pakistani farmers are willing to grow and harvest 18 billion kilograms of wheat per year. The government purchases and stores all surplus wheat.
Suppose that the market-clearing price of Pakistani wheat in the absence of price supports is equal to $0.10 per kilogram. At this price, the quantity of wheat demanded is 12 billion kilograms. Under the government wheat price-support program, how much more is spent each year on wheat harvested in Pakistan than otherwise would have been spent in an unregulated market for Pakistani wheat?
