Here's what caught my eye in research over the past week:
- Tanaka and Matsubayashi (with ungated earlier version here) use county level data from the US from 1979 to 2004, and find that suicide rates increase by 6.76% as sunlight in the current and previous months decreases by one standard deviation
- Danagoulian and Deza (with ungated earlier version here) find that traffic fatalities increase on days in which the local pollen count is particularly high, using US data from 2006 to 2016
- Galiani, Gálvez, and Nachman (with ungated earlier version here) investigate specialisation trends in economics papers from 1970 to 2016, and find that theory and econometric methods papers are becoming increasingly specialised, with a narrowing scope and steady or declining citations from outside economics and from other fields of economics research, while applied papers are covering a broader range of topics, and receiving more citations from other fields like medicine and psychology
