This paper is about the relation between output and labour productivity measures for individual production units and for aggregates such as industries, sectors, or economies. In the framework of discrete time periods several useful, symmetric expressions are derived and confronted with results...

Thefirst objective of this paper is to develop a generic measureof scale efficiency for a multiple-input multiple-output firm,using basic principles of modern production theory. The secondobjective is to combine measures of technological change, technicalefficiency change, and scale efficiency...

Productivity is an important component of profitability, and therefore an important variable for monitoring and benchmarking exercises. This survey discusses the basic accounting model as well as the various measurement problems one gets involved in. By virtue of its structural features, this...

This paper develops the theory of economic price and quantity indicators, being the difference analogue of indexes. The properties of indicators and indexes are compared. Observable bounds for the indicators will be derived, as well as two exactness results for Bennet (1920)-type price and...

In this paper we generalize the concept of scale elasticity to accommodate changes in any direction in the input–output space and not only in the radial input and output directions as was done so far with the conventional scale elasticity measure. Our departure point is that we view the scale...
