Essays on the relationship between sleep and productivity.

我提议的博士论文将涉及使用三种不同的方法来研究睡眠和工作效率之间的关系。第一章将通过孟德尔随机化与睡眠相关的基因型来确定睡眠和生产力之间是否存在因果关系。第二章将着眼于利用一个自然实验，比如在夏天，由于夏令时，时钟提前了一个小时，对睡眠模式造成了短暂的冲击。第三章将着眼于利用时间使用数据来研究睡眠和生产力之间的关系，尽管这种估计不会是因果关系，但它将利用一个非常有用的资源，可以准确测量睡眠时间和白天的活动。

My proposed PhD thesis would involve looking at the relationship between sleep and productivity using three different methods. The first chapter would look to establish if there is a causal relationship between sleep and productivity using Mendelian Randomization with genotypes that are associated with sleep. The second chapter would look to exploit a natural experiment, such as the brief shock to sleeping patterns caused by the advancing of the clock by one hour in the summer due to daylight saving time. The third chapter would look to make use of time-use data to look at the relationship between sleep and productivity, though this estimate would not be causal, it would make use of a highly useful resource that would have accurate measurements of sleep duration and daytime activities.
