Passage 1
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 2014.Unfortunately,that conclusion puts too much weight on a useful,but flawed and incomplete,statistic.Among the more significant problems with the Census's 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 France's 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 economy's 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 incorporated-for example,decreases in total emissions of pollutants and declines in crime rates.
What can we infer from the passage about American people's economic well-being （ ）
根据关键词American和economic well-being，定位至最后两段，根据第七段最后三句话，可以得知，本世纪初到本世纪中期，美国的经济福祉比其他大国都要好。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。这明显与美国人口普查局的报告有出入。AA项中much better与实际程度不符，B项与美国经济福祉持续改善的事实不符，D项有一定的迷惑度，但since mid-2000s与文中的实际时间不符。故本题正确答案选C。
