The city council hired three college interns to measure public support for a large parks and recreation initiative in their city. The interns mailed surveys to 500 randomly selected participants in the current public recreation program. They received 150 responses. In this case, which of the following is the population of interest? A. O The participants who support the initiative B.O All members of the community C.O All participants in the city's recreation program D. O The 150 people who responded E. O The 500 people who got the survey

This was the same question as previously which was answered as A+B. however, that is not an option.  Which quantity is socially optimal (i.e. what is the efficient quantity)? In the stylised model, what is the cost of pollution per high-emission vehicle purchased by buyers equal to?

Consider two groups of citizens, each group can either choose to drive x = d or to take public transport x = p. The first group, group 1, enjoys driving and has the following 3 benefit from using their car within the ULEZ area: B1(x1 = d) = 18. The second group, group 2, does not enjoy driving and has a benefit of B2(x2 = d) = 0 from driving their car. If they don’t drive, citizens can use public transport to get around. The benefit of doing so is the same for both groups: B1(x1 = p) = B2(x2 = p) = 10. Both groups drive cars that do not meet the ULEZ requirements and therefore create excessive pollution.    For simplicity, we consider that pollution, and the health problems it induces, are the main cost of driving. This cost is imposed on both groups and is equal to Ci(x1 = d, x2 = d) = 10 if both groups drive, Ci(x1 = p, x2 = d) = Ci(x1 = d, x2 = p) = 5 if only one group drives and Ci(x1 = p, x2 = p) = 0 if neither group drives, where i represents either group 1 or group 2.
