Employees are part of that market as well. If there are two companies, one paying market wages, and one paying more, the employees will move to the second company. The second company now has a larger pool (and potentially better pool) of candidates to choose from than the first.

The first company may do better on margins per sale, but the second will have better quality/productivity per employee.

This is a valid point, I think the effect will usually be small.

1. If a company is paying above-market wages, then by definition there are more people who want to work there than there are available spots, so the second company will get some of the overflow.

2. The market for a particular kind of labor (e.g. phone techs) is usually much larger than whatever market for outputs these two companies are involved in (e.g., credit-card processing), so one company paying above-market wages is unlikely to change the market wage level very much.

This could definitely break down for some very specialized jobs.
