Mechanism in a nutshell

Two freezes, not one.

When uncertainty rises, firms postpone new jobs, and then postpone refilling the desks that quits leave behind. Replacements are about half of all US hires, so that second freeze is the one this paper is about: how much of the unemployment response to uncertainty runs through replacement hiring.

Two freezes, not one
A stylised example of how replacement hiring can be neutral for unemployment in normal times, and yet raise it once an uncertainty shock freezes that margin too.
