Suppose that there are two cities that are alike in every way except that one city has significantly better weather than the other city. call the city with good weather good-weather city (gwc) and the other bad-weather city (bwc). assume that the median price of a home in the two cities is originally the same. if the marginal utility of living in gwc is 500 and the marginal utility of living in bwc is 300, to make themselves better off economic theory tells us that:
a. at least some people will move from bwc to gwc, which will make housing prices rise in gwc and bwc.
b. at least some people will move from gwc to bwc, which make housing prices rise in bwc and gwc.
c. at least some people will move from bwc to gwc, which will make housing prices rise in gwc and fall in bwc.
d. at least some people will move from gwc to bwc, which will make housing prices rise in bwc and fall in gwc.

Problem 3: access control pokeygram, a cutting-edge new email start-up, is setting up building access for its employees. there are two types of employees: managers and engineers, and there are three departments: security, networking, and human resoures. each employee works in a single department, and each department is housed on a different floor. managers are allowed access to any floor, while engineers are allowed access only to their own floor. there are three badge-operated elevators, each going up to only one distinct floor. every employee has one badge. pokeygram wants to use the best possible access control method in order to minimize delay for the elevators (a) access control matrix, 1. which of the following would you recommend that pokeygram use: (b) access control lists, or (c) capabilities? make sure to justify your answer. 2. what, if any, would be the benefits (and/or disadvantages) of using rbac (role-based access control) in this situation? keep your solution for this problem limited to 10-12 lines of text.
