Money can buy happiness, but up to what point? And does working more make us miserable? And will you be happier if you start your own company? Here’s what the research tells us...
　　金钱可以买到幸福，但能买到多少幸福呢？另外，工作越多会让我们痛苦吗？如果经营自己的公司会更幸福吗？以下是研究告诉我们的结果：
　　1) Generally speaking, richer countries are happier countries. But since many of these rich countries share other traits -- they’re mostly democracies with strong property rights traditions, for example -- some studies suggest that it’s our institutions that are making us happy, not just the wealth.
　　通常说来，富有的国家幸福指数更高一些。然而，由于许多这些富有的国家具有其他一些特性——比方说，这些国家大多比较民主，具有强大的财产权的惯例——因此一些研究显示，是我们的体制使我们幸福，而不仅仅是财富。
　　2) Generally speaking, richer people are happier people. But young people and the elderly appear less influenced by having more money.
　　通常说来，富有的人幸福指数更高一些。然而，年轻人和老年人似乎受金钱的影响更小一些。
　　3) But money has diminishing returns -- like just about everything else. Satisfaction rises with income until about $75,000 (or perhaps as high as $120,000). After that, researchers have had trouble proving that more money makes that much of a difference. Other factors -- like marriage quality and health -- become more relatively important than money. It might be the case that richer people use their money to move to richer areas, where they no longer feel rich. Non-economists might chalk this up to the "keeping up with the Jones’" principle.
　　但是金钱带来的幸福回报在递减——就像其他任何事物一样。满足感随着收入的增长而增长，直到年收入达到75,000美元（或者也可能高达120,000美元）。在那之后，研究人员就发现很难证明更多的金钱能起到多大作用了。其他诸如婚姻质量和健康这样的因素相对来说变得比金钱更加重要。或许事实是这样：富人利用他们的金钱迁到更富有的地区，而在那里他们却不再觉得自己富有了。非经济学人士大概把这一点归结为“互相攀比”原理。
　　3) The diminishing-returns principle is true for entire countries, too... The "Easterlin Paradox" suggests that once a developed country passes a threshold average income, more growth doesn’t increase average reported happiness.
　　满足感递减的原理也适用于所有国家……“伊斯特林矛盾”表示，一旦一个发达国家超过了设定的平均收入水平，那么更多的收入增长并不会增加平均的幸福指数。
　　4) Income inequality reduces well-being, and higher public spending increases well-being. These conclusions have been reached many times ... and called into question many times. Most interestingly, "perceived social mobility" might mitigate the effects of income inequality. If people think they can move up the income ladder, they’re willing to tolerate a larger equality gap.
　　收入不均会降低幸福感，并且更高的公共开支会增加幸福指数。这个论断已经被提及多次……而且曾多次遭到怀疑。更有趣的是，“想象中的社会流动性”或许会缓和收入不均带来的影响。如果人们认为他们可以沿着收入的阶梯向上攀爬，那么他们愿意忍受更大的收入差距。
　　5) Unemployment just makes you miserable. Across most surveys, nothing correlates with unhappiness more than unemployment, except perhaps for bad health. This effect is particularly strong among men in Great Britain, Germany, and the U.S. There is an odd silver lining: Being around lots of other unemployed people makes us feel better about not having a job. So high-unemployment regions can possibly "neutralize" the negative effects of unemployment -- but that shouldn’t make you feel good about them.
　　失业只会让你痛苦。大多数的调查显示，大概除了身体不健康，失业与不幸福的关系最为密切。失业带来的影响在英国、德国和美国男人中最为强烈。有个奇怪的说法是：如果周围有很多其他失业的人，那么我们会对于自己失业这件事感觉没那么糟。因此高失业率地区或许能“抵消”失业带来的负面影响，但是那不应该让你对于失业这件事感觉良好。
　　6) Inflation makes you pretty unhappy, too. But its effect is weaker than unemployment. The mixed evidence seems to suggest that a volatile inflation rate decreases well-being, but in countries with generally stable prices, a little inflation has a small effect on happiness.
