The reason hiring speed reveals more than headcount

Two companies both list two hundred employees. One added ninety of them in the last five months; the other has been flat for two years and replaced eleven leavers. The number on the profile page is identical and describes two entirely different situations.

What everyone sees

Size is read as strength, because size is the figure that gets published and compared. Size is a cumulative record of past commitments, including commitments made under conditions that no longer hold. It says what the firm did, not what the firm currently expects.

What is actually happening

Spence’s signalling framework sets the test for what counts as informative: a signal carries information when it is costly to send and the cost differs by type. Hiring satisfies both conditions, since recruitment is expensive, slow and difficult to reverse without visible damage, so a firm that accelerates it is spending real money on a forecast. Oyer and Schaefer’s survey of personnel economics documents the associated adjustment frictions — hiring and separation costs that make employment levels sluggish relative to conditions — which is precisely why the rate is the more current variable. A level tells you about accumulated past belief. A rate tells you about belief held now, by people with information the outside observer does not have.

Why it stays hidden

The rate hides because levels are published and rates are not. Company pages, funding announcements and press coverage all report totals, so the comparison that is easy to make is the one that carries least information. Reconstructing the rate takes archived snapshots or careful reading of role postings, which is work, and information that requires work is by definition less priced in.
