Assume quantities must be integers. The following table shows a firm's supply function assuming there is neither a tax nor a subsidy. P Q s $110 101 $119 102 $126 103 $140 104 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. You Answered 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. You Answered Correct Answer 29 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. You Answered Correct Answer 51 Value of a quiz drop to the person submitting the higher bid minus the cost Prof. Gazzale incurs to record and process the quiz drop. The cortado, with equal parts espresso and steamed milk, is truly coffee nirvana. In LA, those served at Menotti's are consistently among the city's best. The following table show's Prof. Gazzale's weekly demand when he lived nearby. P Q d $9 1 $7.4 2 $6 3 $4.6 4 $4.3 5 $3.9 6 $3.4 7 $2.1 8 $1.5 9 $1 10 Assuming one cannot purchase partial cortados, by how much does his consumer surplus change if the per-cortado price is $4.1 rather than $6.2?
