The Scope and Organization of Production: Firm Dynamics over the Learning Curve
构建了一个贝叶斯学习模型，解释企业规模与范围如何共同变化，并说明信息成本如何限制企业扩张。适合关注企业成长、组织边界与信息经济学的读者。
I introduce a Bayesian-learning model of the firm to account for a variety of empirical facts about firms. The many tasks the firm can undertake (the scope of the firm) are informationally related, so that the firm can enjoy some economies of scope from information. The model predicts changes in firm size and its comovement with firm scope that are broadly consistent with the empirical evidence. It also provides an explanation for the limits to the scope of the firm: the firm may lack information, or it may be costly to communicate the information necessary to undertake many tasks.
