內容介紹：
Data envelopment analysis (DEA) is a nonparametric technique to estimate production function and technical efficiency of each firm based on the input and output factors. However, demand fluctuation may affect the output level and bias the efficiency analysis when units sold are used at an output measure. This talk defines the concept of effective production and proposes an effectiveness measure to capture the demand fluctuations and sales effect on performance measurement by demand-truncated production function. Effectiveness complements typical efficiency measure. Efficiency measures the relative return on inputs used while effectiveness indicates the ability to match sales given an existing production technology. In addition, the talk also illustrates the estimation of marginal abatement cost (MAC) of undesirable output based on the directional marginal productivity (DMP). The method can avoid estimating MAC of each by-product separately which may lead to an underestimation of the MAC. An empirical study of coal-fired power system is conducted to validate the effectiveness and MAC. We conclude that the proposed effectiveness measure’s ability to distinguish sales and regulation effects from typical productive efficiency, and the DMP also corrects the underestimation issue of the MAC.
