Information in Production
建立了一个模型，分析企业如何利用关于个人生产能力的特定信息，并考察信息质量改善对均衡产出、工资率和专业化程度的影响。
THIS PAPER PRESENTS a simple model of the manner in which person-specific information on productive capabilities is put to use in the firm. The analysis is then employed to examine the impact of improved information quality on equilibrium output, wage rates, and degree of specialization. Much effort has been devoted to studying the process through which personspecific information is accumulated. Burdett-Mortensen [1], MacDonald [8], Prescott-Visscher [10], Hartog [3], and Johnson [5] examine the process of learning about person-specific parameters through investment of resources in activities that yield information. Jovanovic [6] analyses the more specific problem of inferring the quality of a particular job-worker match. Little attention has been given to the question of just how the firm utilizes this kind of information. For information to play an interesting role in production, two things are necessary. One is that workers be heterogeneous in a meaningful sense. That is, in the space of productive characteristics, workers must not all be simply scalar multiples of one another. Second, the firm must have some choice about the kind of activities in which workers are engaged. If either of these conditions fails, the optimal assignment of workers is not a problem.2
