Project 2: Questions on Lessons 6-11 Question 1: a) $13 and 6 quantity b) $12 c) $15 d) $2 e) $1 f) 0.5*3*2= 3
Question 2: a) The equilibrium price and qty is found at a price of $30 and qty demanded/supplied at 7 million. This is the equilibrium because this is where the quantity demanded and quantity supplied curves intersect, showing the optimal price for buyers and the sellers. b) The new market price is $50, at this price point, 3M Recoins are demanded while 13M are supplied. This therefore causes a surplus of 10M Recoins (13M supplied – 3M demanded). c) The new market price is $20 – with 12M Recoins demanded and only 4M supplied. This would lead to a shortage of 8M Recoins. d) Because the equilibrium price is at $30, implementing a price ceiling at $40 will have no effect on the supply and demand as customers are paying the optimal price of $30. Suppliers would also find their optimum output at 7M
Question 3: a) # of Units at Q1 will be purchased b) A,B, and C c) # of Units at Q2 will be purchased d) A

Question 4: a) When the cost of producing batteries decrease, there is a downward-right shift in the supply curve to reflect the change. This will then cause the price to decrease from P1 to P2, thereby also causing consumer surplus to increase. The equilibrium has also moved from P1,Q1 to P2,Q2 b) With the downward-right shift of the supply curve, the consumer surplus area increases from A to A+B+D. Meanwhile, because the price of batteries decreased and the supply curved shifted downwards, the producer surplus shrank and is now represented by C within the area of P2 and QS2. The total surplus area is comprised of A+B+C+D
c) If the QS curve was elastic, then the consumer would stand to benefit as the Consumer Surplus (CS) would be the area between QS and the QD line.
Question 5: a) It is a negative externality because the added traffic negatively affects the local community b) The graph below shows the private cost curve and its upward-right shift by $6 to represent both the private and added external cost to the community. c) The newly discovered externality of $2 would be considered a positive externality as it is an added benefit to the community

d) With the added inclusion of the $2 shift, we can see that the Qoptimum has shifted from Q1 to Q2, this is due to the fact that both the demand and supply curves have shifted to reflect the externalities from the art gallery
Question 6: a) If there were a sudden increase in demand in a perfect competition, we would see the demand curve shift to the right, similarly to the graph below and this would occur because the demand for wine has increased thereby causing the suppliers to maximize on this opportunity and increases prices, while also seeing an increase in demand from buyers. We can see the new market equilibrium at P2 and Q2. b) No the result will not last. We can see that initially there is no economic profit as the market is in equilibrium, however with the increase in demand + price increase, we see that firms begin to make economic profits, which would then entice new wine suppliers to enter the market, which would lead to new competition, thereby causing firms to lower prices again.

Question 7: a) Price and quantity is shown below at P1 b) The total surplus is in Areas A,B
c) The total profit would be A,B, and C. Because they can tailor their pricing to meet different demand groups, any area highlighted below the demand curve and above the MC curve would be considered profit. d) As mentioned in C, the profit from price discrimination moves from just A to A,B,C. This is because the company can now tailor its pricing to capture all the demand for their services. This leads to the deadweight loss (area C) and the surplus area (b) to now be captured as profit.
