Therefore, the ‘market outcome’ is 11—qa=1 :> qam=10 G—QbZl => gbm=5 b. In the market outcome, each person disregards the beneﬁt his plants have on the other. Therefore we expect that each buys less that the ‘socially optimal’ amount and so the total number of plants will be less than the efﬁcient one. Note that the plants in A’s garden are ‘consumed’ by both A and B so they are a ‘public good’. The same is true for the plants in B’s garden. 0. Let M S B A be society’s marginal beneﬁt (or MTWP) for plants in A’s garden. It follows from the above that M SB A is equal to the sum of the individual MB’s. From the table: MSBA = (11 —qa)+ (1) = 12—6111 Likewise, letting M SB 3 be society’s marginal beneﬁt (or MTWP) for plants in B’s garden, we get MSBB=(1)+(6—Qb)=7—Qb Society’s welfare is maximized when M S B A = p and M SB B = p. Therefore, we get 12—qa21 :> (1*:11 —a¥ 7—Qb=1 => (13:6 As expected each person actually plants less than the efﬁcient amount. 4. MWTP(1) = (1000) + (1300) = 2300 > 1500, MTWP(2) = (1800 — 1000) + (x1300) = 800 —1300 + x 2 X500 < 2000 so x < 2500 Q*=1, for X > 2500 Q*=2. 5. See notes. ...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
