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.

Reliability and validity reliability and validity are two important considerations that must be made with any type of data collection. reliability refers to the ability to consistently produce a given result. in the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. to illustrate this concept, consider a kitchen scale that would be used to measure the weight of cereal that you eat in the morning. if the scale is not properly calibrated, it may consistently under- or overestimate the amount of cereal that’s being measured. while the scale is highly reliable in producing consistent results (e.g., the same amount of cereal poured onto the scale produces the same reading each time), those results are incorrect. this is where validity comes into play. validity refers to the extent to which a given instrument or tool accurately measures what it’s supposed to measure. while any valid measure is by necessity reliable, the reverse is not necessarily true. researchers strive to use instruments that are both highly reliable and valid.
