For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Economically speaking, are we better off than we were ten years ago? Twenty years ago?In their thirst for evidence on this issue, commentators seized on the recent report by the Census Bureau, which found that average household income rose by 5.2% in 2015. Unfortunately, that conclusion puts too much weight on a useful, but flawed and incomplete, statistic. Among the more significant problems with the Censuss measure are that: 1) it excludes taxes, transfers, and compensation like employer-provided health insurance; and 2) it is based on surveys rather than data. Even if precisely measured, income data exclude important determinants of economic well-being, such as the hours of work needed to earn that income.While thinking about the question, we came across a recently published article by Charles Jones and Peter Klenow, which proposes an interesting new measure of economic welfare. While by no means perfect, it is considerably more comprehensive than average income, taking into account not only growth in consumption per person but also changes in working time, life expectancy, and inequality. Moreover, it can be used to assess economic performance both across countries and over time.The Jones-Klenow method can be illustrated by a cross-country example. Suppose we want to compare the economic welfare of citizens of the U.S. and France in 2005.In 2005, as the authors observe, real consumption per person in France was only 60% as high as the U.S., making it appear that Americans were economically much better off than the French on average. However, that comparison omits other relevant factors: leisure time, life expectancy, and economic inequality. The French take longer vacations and retire earlier, so typically work fewer hours; they enjoy a higher life expectancy, presumably reflecting advantages with respect to health care, diet, lifestyle, and the like; and income and consumption are somewhat more equally distributed there than in the U.S. Because of these differences, comparing Frances consumption with the U.S.s overstates the gap in economic welfare.Similar calculations can be used to compare the U.S. and other countries. For example, this calculation puts economic welfare in the United Kingdom at 97% of U.S. levels, but estimates Mexican well-being at 22%.The Jones-Klenow measure can also assess an economys performance over time. According to this measure, as of the early-to-mid-2000s, the U.S. had the highest economic welfare of any large country. Since 2007, economic welfare in the U.S. has continued to improve. However, the pace of improvement has slowed markedly.Methodologically, the lesson from the Jones-Klenow research is that economic welfare is multi-dimensional. Their approach is flexible enough that in principle other important quality-of life changes could be incorporatedfor example, decreases in total emissions of pollutants and declines in crime rates.全文翻译及命题分析从经济上讲，我们的生活比十年前或二十年前更好吗？评论员从美国人口普查局最新的一份报告着手，渴望在这个问题上找到证据。该报告发现，2015年的家庭平均收入增长了5.2%。不幸的是，这一结论过于强调统计数据，而该数据虽有效，但有缺陷和不完整。统计调查在衡量测算方面有如下重要问题：1)它不包括税收、转账和补偿，如雇主提供的健康保险；2)它基于调查而不是数据。即便调查结果是精确的，收入数据也将一些经济福祉的重要决定因素排除在外，如赚取收入所需的工作时间。在思考这个问题的时候，我们看到了查尔斯琼斯和彼得克勒诺最近发表的一篇文章，文中提出了一种新颖有趣的经济福祉衡量标准。它谈不上完美，但比平均收入作为唯一衡量指标要全面得多。它既考虑到人均消费的增长，也考虑到工作时间、预期寿命的变化和经济不平等等因素。此外，它既可以用于对比国与国之间的经济业绩，也可以用于评估某个国家在某个时间段的经济业绩。琼斯和克勒诺提出的方法可以通过一个跨国案例加以说明。假设我们想将2005年美国和法国公民的经济福祉进行对比。2005年，正如作者所观察到的，法国的人均实际消费仅为美国的60%，表面上美国人的经济状况似乎比法国人的平均水平要好得多。然而，这种比较忽略了其他相关因素：闲暇时间、预期寿命和经济不平等。法国人休假时间更长，退休时间更早，因此通常工作时间更短；他们的预期寿命更长，大概反映了法国在医疗保健、饮食、生活方式等方面的优势；法国的收入和消费分配相对于美国也要更均衡一些。由于这些差异，60%这一比较数据夸大了两国在经济福祉方面的差距。类似的计算也可以用来比较美国和其他国家。例如，这种计算将英国的经济福祉水平定为美国的97%，而墨西哥人的福利水平约为美国的22%。琼斯和克勒诺提出的衡量标准也可以用来评估某个国家在某个时间段的经济业绩。根据这一标准，本世纪初到本世纪中期，美国的经济福祉比其它大国都要好。自2007年以来，美国的经济福祉持续改善。然而，改善的速度明显放缓。从方法上讲，琼斯-克伦诺研究所得出的教训是，经济福祉是多维的。他们的方法足够灵活，原则上包括了其他重要的生活质量方面的变化，如污染物总排放量的减少和犯罪率的降低。【命题分析】本题包括多种阅读理解题型，既有细节题，也有观点态度题和推理判断题，因此有一定难度。【内容概要】本篇阅读理解介绍了一种衡量经济福祉的新方法Jones-Klenow method。它包含了影响生活质量的更多因素，比美国人口普查局所采用的方法更全面更灵活。【试题详解】46.
