It is true that social sciences are not the same the natural sciences. Experiments have been used successfully to tellus more about the world we live in. There are limits that social scientists should be aware of, but to dismiss the use of experimental analysis entirely would be incorrect.2. When the data used in an econometric analysis are not carefully screened for errors, there can be faulty and misleadingresults that occur. There has bee n some time expended to ensure that the data have been “cleaned” properly.3. Reasoning resulting in differing results includes the time period under examination, the data sources and proxies used,the econometric tools employed, and many others reasons. This is not to say that because different researchers come to different conclusions the analysis is confused. It just means further investigation is needed.CHAPTER 3 –规范分析工具Multiple-Choice Questions1.

Social welfare functions can be formed in many ways. They can be additive, meaning that the all utilities curvesare added together. They incorporate the idea of least-best, meaning that the utility of the person with the least ismaximized.

Since the MRSs of the two are equal at every point in the Edgeworth Box, every point is Pareto.2. The optimum would be a corner solution found the same way as if goods were perfect substitutes. Percy receivesnone, and all goes to Leroy.3.

Horizontal adding yields Q = 33 –P. Vertical adding yields P = 66 –4Q.2. At a marginal cost of $24, the social marginal benefit curve is too low to afford any level of snow plowing.3. Q* = 14.4. The demand curve has two portions. When Q is between 0 and 16, the demand curve is Q = (64/3) – (P/3). When Q is between 16 and 32, the demand curve is Q = 32 – P.5. The two curves never intersect at a positive quantity; therefore, the amount of the public good provided will be zero. Answers to True/False/Uncertain Questions1. T2. T3. U4. F5. F6. T7. T8. U9. T10.
