The question that is at the core of this issue is easy to state. What should an employer do about a factor of production, be it physical capital such as a plant or machine or be it human capital, that has become unprofitable? For human capital, that is, skills and knowledge, the lack of profitability may stem from the fact that the worker's basic skills were never adequate or it may be the case that technology or workplace demands have surpassed the worker's skill levels. For both physical and human capital, the choices that employers face are limited. They can invest in upgrading the factor of production; they can continue to employ the factor and bear the losses; (Note: I am using the economic cost concept of opportunity costs. A basic skills deficient worker may be paid $8.00 an hour and be productive enough to produce $8.50 worth of product per hour. However, a trained employee or a younger employee may be willing to work for $8.00 an hour and be able to produce $10.00 worth of product. The opportunity cost of not training the worker would be $1.50 per hour even though the firm would not be losing money on the worker.) or they can replace the factor. From an economic and business management theoretical point of view, the answer is easy. Employers should choose the option that maximizes their rate of return. That is, they should choose the option where the difference between the (discounted) future benefits and the costs is the greatest. From a practical point of view, estimating the benefits and costs may be extremely difficult. Furthermore, it is undoubtedly the case that the best option will differ for different situations. There may be cases in which employers would reap large returns from modest investments in workplace literacy training. On the other hand, there may be cases in which employers would be better off by accepting the turnover and hiring costs of replacing workers. In short, it is impossible a priori to prove that it is to a firm's advantage to provide workplace literacy training. It, too, is impossible to prove a priori that it is to a firm's advantage to shed workers with basic skills deficiencies.
From a public policy point of view, it should be recognized that society may benefit or bear costs from employers' decisions about inefficient or outmoded factors of production. Thus it may be the case that from a firm's profit-maximizing perspective, it is not advantageous to provide workplace literacy training. But from the rest of society's perspective, provision of the training, is beneficial. In such cases, public policy should facilitate financial subsidies to firms.
The purpose of this paper is to present these arguments theoretically to identify the key factors that influence the employer's and society's choices; to discuss some empirical evidence from earlier studies about the payoff to individuals and firms; and to provide policy recommendations.
