CBC interviewed Werner Antweiler, a professor at UBC’s Sauder School of Business, about research that shows switching between standard time and daylight saving time has more costs than benefits.
In 2015 Antweiler surveyed studies on daylight saving time and said negative patterns only become apparent when researchers study the entire range of effects.
“It turns out that on that Monday after the shift in the spring there is a drop in the stock prices and that actually calculates to something like $31 billion in losses on the stock market in just one day. It’s later recovered, but on that one day, there is a very sizable effect,” he said.
In a similar story in Metro News, Mark Levi, a UBC psychiatry professor, found the “Monday” effect, when workers are less productive at the start of the week, is “magnified” by 200-500 per cent on the Monday following the end of daylight saving time. Levi calculated the effect could result in a $31 billion one-day loss on the stock exchange.
