Prices, especially resource prices, tend to be inflexible for five reasons.

• First, producers often have long-term, multi-year contracts with resource suppliers that specify resource prices. The best example is collective bargaining agreements between firms and labor unions. For most employers, as well as the labor unions, it is often easier to lay off a few workers temporarily than it is to renegotiate an agreement that contains lower wages.


• Second, workers tend to view wages as an indication of intrinsic self-worth. If an employer should try to reduce wages, workers are inclined to view this as a personal insult. These workers might then opt for temporary unemployment, awaiting to be re-hired or seeking other jobs AT EXISTING WAGES, rather than continuing their current work at lower wages.


• Third, the processes involved with employing and paying workers, especially such things as payroll systems, are often guided by inertia. Once wages are established (that is, entered into computer databases) explicit actions must be taken to change them. Because these actions are not costless, firms need a good reason to make changes. In other words, firms employing thousands of workers are unlikely to make small daily, weekly, or even monthly changes in wage rates.


• Fourth, firms might actually opt to reduce employment rather than wages as a means of getting rid of the least productive workers. In other words, the firms can use a decline in sales and production as an opportunity to "clean house." Once done, the firm ends up with a workforce that is, on average, more productive and more efficient. For example, a firm with ten employees that needs to cut wage cost by 10 percent might be inclined to fire one worker, the least productive, rather than cutting wages for all ten workers.


• Fifth, many firms, especially small ones, are price takers in resource markets. They have NO control over the resource prices set by the market. Should they find it necessary to cut wage cost, their ONLY option is to reduce employment and production.
