A Dynamic Model of Investment and Capacity Utilization
构建了一个企业动态优化模型，考虑准固定要素的调整成本，企业最优选择其利用率，投资基于影子价格（类似托宾q理论），并分析投资与利用率在稳态路径和需求冲击下的关系。
This paper develops a dynamic optimizing model of a firm with quasi-fixed factors subject to adjustment costs. The utilization rates of the quasi-fixed factors are chosen optimally by the firm, and the rates of investment in the quasi-fixed factors are based on the shadow prices of these factors, in the spirit of Tobin's q theory of investment. Capital investment is shown to be negatively related to capital utilization along the path to the steady state; however, in response to unanticipated demand shocks, capital utilization and investment are positively related.
