研究：睡得越多赚得越多

Within a single time zone, the time of sunset varies substantially, as the map below shows. For example, the sun sets about an hour and a half earlier in Mars Hill, Maine, than in Ontonagon, Mich., even though both are in the Eastern time zone. Because there shouldn't be any significant differences in workers on the eastern or western edge of a time zone beyond the amount of time they sleep, researchers use this variation to calculate how much sleep influences wages.

如下图所示，在一个时区里日落时间相差很大。比如，虽然同在东部时区，缅因州马斯希尔的日落时间比密歇根州昂托纳贡的早一个半小时。因为不论在一个时区的东边还是西边，员工的睡眠时间应该没有显著差别，研究人员决定用日落时间的差异来计算睡眠对工资的影响。

They find that a one-hour increase in average weekly sleep in a location increases wages by 1.3 percent in the short run, which include changes of less than a year, and 5 percent in the long run. By moving to a location where a sunset is one hour earlier, a worker will make an additional $1,570 a year.

他们发现，在一个地区，平均每周增加1小时睡眠，工资一年以内增长1.3%，而从长期来看增长5%。如果搬到日落早一小时的地区，员工的工资一年将增加1570美元。

Those differences in wages end up being incorporated into the local economy. The researchers find that higher wages actually translate into higher home values as well. A county that experiences a sunset one hour earlier has on average a 6 percent higher median home value, about $7,900 to $8,800 dollars, they say.
