This paper deals with the calculation of shadow wages for family labour in agriculture. Using the existence of a duality between input distance and cost functions, we use the former to derive individual labour shadow prices for a sample of Spanish citrus fruit producers. Our results show that...

Outsourcing in agriculture has traditionally been seen as a managerial strategy of smaller farms to achieve higher levels of efficiency. In this article, we provide empirical evidence supporting the existence of a positive relationship between outsourcing and efficiency in Spanish citrus...

In this paper, we test for convergence in the environmental performance of a sample of OECD countries, with data ranging from 1971 to 2002. First, we use Data Envelopment Analysis (DEA) to compute two environmental performance indicators (EPIs) in the production theory framework. Second, we...

Quality is a dimension of water services that has been repeatedly omitted in the study of performance of water utilities. In this paper, we make use of Data Envelopment Analysis techniques (DEA) to compute both conventional quantity-based and quality-adjusted indicators of technical efficiency...

Discrete choice models such as the conditional logit model are widely used tools in applied econometrics and, particularly, in the …eld of environmental valuation and welfare measurement in order to provide policymakers with sound information for making strategic choices. Monte Carlo...

This paper studies convergence in CO2emission intensity (CO2 emissions over GDP) among OECD countries over the period 1960-2008 based on its determinants, namely, energy intensity (energy consumption over GDP) and the so-called carbonisation index (CO2 emissions over energy consumption). We...

Eco-efficiency refers to the ability to produce more goods and services with less impact on the environment and less consumption of natural resources. This issue has become a matter of concern that is receiving increasing attention by politicians, scientists and academics. Furthermore,...

This paper studies convergence in CO2 emission intensity (CO2 over GDP) among OECD countries over the period 1960-2008 based on its determinants, namely, energy intensity (energy consumption over GDP) and the so-called carbonisation index (CO2 emissions over energy consumption). We apply the...

In countries where privatisation is permitted by law, policymakers usually give different reasons of general interest to allow private companies to manage water services. However, these kinds of decisions often provoke intense political debate and are at times opposed by citizens. In this paper,...
