摘要 基于以下证据：(a) 随着技术经验的积累，干中学的生产率增长会减弱；(b) 干中学很大程度上针对每种生产技术，本文对企业何时更新其技术的决策进行了建模。该模型意味着技术更新会内生地带来生产力的大幅下降。该模型还意味着，在繁荣时期比在衰退时期更有可能进行技术更新，因为高生产率使公司能够更快地了解新技术。该模型中的力量可能有助于解释工厂和行业层面数据的一些特征，例如投资的顺周期性（包括工厂投资峰值）以及劳动力投入与生产率之间的适度相关性。经济文献杂志分类号：O31、L6、D92。
Abstract Building on evidence that (a) productivity growth from learning by doing diminishes as experience accumulates with a technology and (b) learning by doing is largely specific to each production technology, this paper models a firm's decision of when to update its technology. The model implies that technology updates endogenously bring large drops in productivity. The model also implies that technology updates are more likely in a boom than in a recession since a high rate of production enables the firm to learn more quickly about the new technology. The forces in this model may help explain some features of plant and industry level data, such as the procyclicality of investment (including plant investment spikes) and the modest correlation between labor input and productivity.
