Time zone lines and suicides: west side story.
نویسنده
چکیده
Suicide is a major cause of death in the USA and worldwide. There is a puzzle over the influence of sunlight on suicides that dates back to 1897: On the one hand, lack of sunlight is linked to seasonal affective disorder, and thereby more suicides. And yet curiously, the suicide rate peaks in spring/summer and midday. This paper sheds light on this debate, identifying the separate role of sunlight, as opposed to cultural influences on suicides. I compare the suicide rates of counties along the three major time zone lines in the USA. Using a random effects panel regression, I show that a short move to the west side of any time zone line significantly inflates the suicide rate by about 10%. Beyond the scientific value for epidemiology, these results have economic ramifications for location choices, and raise questions about current time zone placements. 1 Email: [email protected].
