We study the relation between workers� skill dispersion and firm productivity using a unique dataset of Italian manufacturing firms from the early eighties to the late nineties with individual records on all their workers. Our measure of skill is the individual worker�s effect obtained...

The paper investigates the organization of the Italian water sector in the light of the reforms of public utilities. The aim is to examine the degree of implementation of the water sector reform (the so-called Galli Law of 1994) and assess the performance of operators through a study of their...

The paper presents the first ex-post analysis of profit and productivity of individual vessels following a vessel or licence buyback in a fishery. Using individual firm-level data for the period 1997-2000, the paper analyzes a "natural experiment" of the effects of a 1997 scheme to reduce...

In this article we examine the effects of undesirable outputs on the Malmquist TFP indices. Our empirical work uses an unbalanced panel which covers 796 utility and non-utility coal-fired power plants in China during 1996-2002. In order to meet the requirement of a balanced panel for calculating...

The allowance allocation under the European Emission trading schemes differs fundamentally from earlier cap and trade programs, like SO2 and NOx in the USA. Because of the iterative nature of negotiations of the overall budget, the allocation also has to follow an iterative process. If power...

Different from traditional efficiency research and previous studies considering undesirable outputs, this paper proposes models which distinguish weak and strong disposability features among various undesirable outputs based on the technical nature of the undesirable outputs. The paper...
