Side question, is the 3-4 months of severance pay cushioning a bit the impact to whatever micro-economy laid off workers would otherwise be affecting? We're not yet seeing the potentially worse effects yet until severance runs out? But I would hope that most laid off workers are able to find jobs in that time frame.
There's 120k US layoffs documented here in 2023, or 0.07% of the US workforce. We could imagine the ~50% reemployment rate for FANG is a fair estimate for the rest of the tech layoffs (fang employees might be easier to be rehired, but might have more savings and be less inclined to return). So 0.035% of the workforce would potentially be running out of severance.
It probably will have an impact. This alone isn't a crisis level event. It's hard to determine regional data for the laid off workers because of WFH, but we could imagine tech heavy regions receiving a bigger share of the impact than national averages. The impact is probably more spread than it would have been if the layoffs happened in 2019.
