We explore the effect of balancing unbalanced panel data when estimating primal productivity indices using non-parametric frontier estimators. First, we list a series of pseudo-solutions aimed at making an unbalanced panel balanced. Then, we discuss some intermediate solutions (e.g., balancing...

In the literature, two main ratio-based productivity indices have been defined in terms of a primal technology notion. While the Malmquist productivity index has become very popular, it has the problem that it is not always well-defined. By contrast, the less popular Hicks Moorsteen productivity...

There are two total factor productivity indices available in the literature based on a primal notion of the technology. In a ratio tradition, these are the Malmquist and the HicksMoorsteen productivity indices. In a difference perspective, the Luenberger and Luenberger-Hicks-Moorsteen...

Introducing a new difference-based Luenberger-Hicks-Moorsteen productivity indicator, this contribution establishes theoretically its relations with some existing ratio- and difference-based productivity indexes and indicators. The first main result is an approximation proposition stating that...

The specification of a convex production technology is a potential issue in estimating firm-level Johansen plant capacity utilisation rates and their subsequent use in the short-run Johansen industry capacity model of the fishery. There are different plant capacity utilisation estimates with...
