Grifell-Tatjé, E., and C.A.K. With this mind, we can define dynamic efficiency as an aspect of economic efficiency that measures Christensen, and W.E. Estimation of efficiency is usually done for units observed during the same time period; thus, in this respect, the measures are static.

Dynamic data envelopment analysis: modeling intertemporal behavior of a firm in the presence of productive inefficiencies. Quite often, company management is measuring … In Section 2 the attempts in the literature to explain inefficiency will be reviewed, as well as the definitions of a frontier production function, and the concept of dynamic efficiency. The quantitative method measures productivity by the number of parts or products an employed produces in a particular period of time, such as per hour, day or month.. Dynamic efficiency is a central issue in analyses of economic growth, the effects of fiscal policies, and the pricing of capital assets.

Measurement of dynamic efficiency in production: an application of data envelopment analysis to Japanese electric utilities. There are some methods for measuring efficiency deviations over time, for example, window analysis and the Malmquist index. Static measures often outlive their usefulness, such as direct labor efficiency. Technical progress and structural change in the Norwegian aluminium industry. The literature points to measures of inputs and management as not including quality dimensions as a reason for measured efficiency differences, indicating that more work needs to be done on data collection.
