An Analysis of Production Cost Inefficiency

This research empirically investigates the presence of production cost inefficiencies associated with non-optimal operating conditions. A model is developed which allows for the possibility that firms might be temporally constrained in their production decisions due to a quasi-fixed capital stock. The context of the study is the household goods motor carrier industry in the post-deregulatory period. The analysis employs a technique capable of quantifying excess per unit costs and decomposing this magnitude according to its determinants. Specifically, it identifies and measures three types of inefficiency at the firm level: short-run capital inefficiency, capital-induced variable input inefficiency, and X-inefficiency.
