Why wage effects differ by job
Migration adds workers to a local labor market, but workers do not all compete for the same jobs. The key question is how closely newcomers’ skills and experience match the work employers need done.
Where newcomers and existing workers are close substitutes—able to do similar tasks—more applicants can ease hiring pressure. That may slow wage growth in those jobs, especially if employers had been raising pay to attract scarce workers. It does not automatically mean wages fall: demand for the work, business growth, and other local conditions matter too.
More workers can also create demand
Some workers complement one another: each makes the other’s work more productive or helps a business expand. If a growing workforce lets a restaurant serve more customers, for example, it may increase demand for supervisors, bookkeepers, or technicians. Those roles can remain hard to fill even as hiring becomes easier in other positions.
Specialized skills also do not appear instantly. A region may gain workers overall while still lacking people with the licensing, training, or experience needed for particular jobs. In that case, employers may continue competing for those workers and raising pay, even as wage growth slows in occupations with a larger pool of applicants.
The local labor market is many markets
“Wages” can obscure these differences. Effects depend on occupation, skill level, and how employers respond—not just on how many people live in a place. A larger workforce can ease pressure in one kind of job while leaving a shortage, and upward wage pressure, in another. That is why a single local wage figure can miss what workers in different industries are experiencing.
