Height and Earnings

A new paper by Princeton University economists Anne Case and Christina Paxson says taller people earn more because they are smarter. The abstract:
普林斯顿大学的经济学家,Anne Case和Christina Paxson在一份新的研究报告中称:个子高的人,收入也更多,因为,他们更聪明。摘要如下:

Ithas long been recognized that taller adults hold jobs of higher statusand, on average, earn more than other workers. A large number ofhypotheses have been put forward to explain the association betweenheight and earnings. In developed countries, researchers haveemphasized factors such as self esteem, social dominance, anddiscrimination. In this paper, we offer a simpler explanation: Onaverage, taller people earn more because they are smarter. As early asage 3 — before schooling has had a chance to play a role — andthroughout childhood, taller children perform significantly better oncognitive tests. The correlation between height in childhood andadulthood is approximately 0.7 for both men and women, so that tallchildren are much more likely to become tall adults. As adults, tallerindividuals are more likely to select into higher paying occupationsthat require more advanced verbal and numerical skills and greaterintelligence, for which they earn handsome returns. Using four datasets from the US and the UK, we find that the height premium in adultearnings can be explained by childhood scores on cognitive tests.Furthermore, we show that taller adults select into occupations thathave higher cognitive skill requirements and lower physical skilldemands.
长期以来,人们已经认识到,个子高的成年人,也能得到地位高一些的工作,平均收入也超过其他人。人们提出了大量的假设,来解释身高与收入之间的关系。在发达国家,研究人员强调的因素有自我评价、社会地位和辨别能力等。在本文中,我们给予了一个简单的解释,身高高于平均身高的人,他们的收入也更高一些,因为,他们更聪明。例如,早在三岁,即学龄前,就已经发挥其优势,直至贯穿于整个童年阶段,高个子的儿童,在认知测试中的表现更突出。童年的身高与成年身高之间的相关性约为0.7,因此,高个子儿童更容易成为身材高的成年人。个子高的人更容易选择到高报酬的职业,他们为了赚取可观的收入,必须具备很强的语言能力,数学能力及理解力。从分别来自美国和英国的四数据中,我们发现,那些高收入的成年人,都可以从儿童时期的认知测试成绩中找到答案。此外,我们研究发现,那些高个子人选择工作,总是选择那些对智能要求高、对体能要求低的工作。
