This paper analyzes the impacts of Italian government actions on the efficiency of 36 airports between 2001 and 2003. The changes have included privatization, enlargement of the services provided directly by airport management companies, through the modification of the concession agreements, and the creation of two hubs. The analysis, using the consolidated two-stage data envelopment analysis with bootstrapping, indicates that airports with a majority public holding are on average more efficient and the presence of two hubs is source of inefficiency. 相似文献

A bootstrapped DEA procedure is used to estimate technical efficiency of 18 Italian airports during the period 2000-2004. Departing from previous studies, we separate the efficiency related to ability to manage airside activities (operational) from that related to the management of all business activities (financial). In general, Italian airports operate at poor levels of efficiency, with slightly better performance in terms of their financial activities. In the current study, selected intrinsic and environmental characteristics are considered as possible drivers of Italian airport performance. In particular, we found that: (i) the airport dimension does not allows for operational efficiency advantages, (ii) on the other hand, the airport dimension allows for financial efficiency advantages for the case of hubs and disadvantages for the case of the smallest airports (iii) the type(s) of concession agreement(s) might be considered as important source of technical efficiency differentials for those airports running marginal commercial activities; (iv) the introduction of a dual-till price cap regulation might create incentives which lead to the increase of financial efficiency at the detriment of the operational performance. Lastly, the development of a second hub (Milano Malpensa), has negatively affected the performance of the country’s national hub (Roma Fiumicino). 相似文献

Psychometrically sound evaluation measures are vital for examining the contribution of professional training to organizational success in a reliable manner. As training evaluations tend to be both time‐consuming and labor‐intensive, there is an increasing demand for economic evaluation inventories. Simultaneously, evaluation measures have to meet psychometric standards. The present paper develops a time‐efficient training evaluation questionnaire that (1) has psychometrically sound properties; (2) measures more than the participants’ reactions; and (3) is widely applicable across different training contents, thus allowing for comparisons of training programs within and between organizations. The Questionnaire for Professional Training Evaluation is primarily developed for use in practice but is also applicable to field research and covers short‐term as well as long‐term training outcomes. Analyses based on a total of n = 1134 employees show the stability of the factor structure and hint at the questionnaire's differential and discriminant validity. Theoretical and practical implications are discussed. 相似文献

Using the integer programming approach introduced by Sethuraman et al. (2003), we extend the analysis of the preference domains containing an inseparable ordered pair, initiated by Kalai and Ritz (1978). We show that these domains admit not only Arrovian social welfare functions “without ties,” but also Arrovian social welfare functions “with ties,” since they satisfy the strictly decomposability condition introduced by Busetto et al. (2015). Moreover, we go further in the comparison between Kalai and Ritz (1978)’s inseparability and Arrow (1963)’s single-peak restrictions, showing that the former condition is more “respectable,” in the sense of Muller and Satterthwaite (1985). 相似文献

Sustainable land use planning is crucial for realizing the aim of food security and for combating land degradation in the Sahel. A participatory land use planning workshop was organised in a village in the eastern region of Burkina Faso to investigate land use problems, their causes, effects and possible solutions. Participatory research tools and GIS were combined to get insight into possible conflicts or synergies between different land use options as mapped by different ethnic groups. Pictograms were used to locate alternative land use options on the map, after which they were digitised for analysis with GIS. The workshop confirms the importance of integrating scientific and local knowledge to develop concrete options for sustainable land use that fit to local realities and aspirations. Local people are knowledgeable about the driving forces behind land degradation, they take actions to combat the effects of degradation, and they have concrete ideas about alternative land use options. The use of GIS proved its added value in the participatory process of integrated land use planning. The maps that were produced also facilitate discussions between community members, researchers and government representatives at the regional level, both regarding current land use problems and regarding alternative options as perceived by the local population. 相似文献

One of the objectives of agricultural policy worldwide concerns the support of farm income. Common Agricultural Policy direct payments (DPs) are the main instruments to support farm income in the European Union. This article addresses their role in the concentration of farm income. This is done by calculating the Gini coefficient and its disaggregation in a large sample of Italian farms in the period between 2006 and 2007. Although this approach has been used to develop ex‐post analysis in previous studies, this article is innovative given that it is used here in an ex ante analysis aimed at evaluating the likely impact of a recent reform proposal. This latter requests changing the current model to a regional model of DPs application to make payment rates (i.e., payment per hectare) homogeneous among farms in the same region. The analysis shows that DPs and farm incomes are both very concentrated but that DPs allow for an income concentration reduction in Italian farms. The shift to a regional implementation reduces DPs concentration and, to a limited extent, farm income concentration. Of the considered regionalization scenarios, those that redistribute DPs among regions are the most effective in reducing concentration. The extension of the Gini considered approach to an ex ante setting seems effective because it provides insights that could feed the policy debate regarding the forthcoming reform. 相似文献

Post Offices Inc. in The Netherlands has developed and implemented a new instruction model for the training of desk employees. The quality of the new instruction model was assessed by means of the evaluation model of Jacobs and Jones for on‐the‐job training. It is concluded that the implementation of the training model has not been completely successful. Critical success factors, such as the performance of the mentors as well as the quality of the self‐study material, have to be improved. Mentors are expected to serve as a behavioural model, to provide feedback, arrange an adequate environment for self‐study, motivate trainees for self‐study and evaluate trainees’ progress on a regular basis. This study shows that mentors must be fully convinced of the benefit of a new instructional model, if not, the implementation will not be successful. Besides, the study shows that the quality of the self‐study material depends very much on the similarity between the knowledge needed in work and the knowledge presented in the self‐study material. 相似文献

This paper shows that under weather variability the transformation from a rural to an incomplete market economy can increase the vulnerability of peasants to famine. This can occur even if improvements in technology have raised agricultural productivity and made production less responsive to weather variability. Indeed, negative environmental shocks can produce a drop in wages that outweighs the increase in wages due to an equivalent positive environmental shock. Consequently, the amount of grain stored increases more slowly in good seasons than it decreases in bad ones. This paper gives new insights on the catastrophic effects produced by widespread droughts in India during the second half of the 19th century. Notwithstanding the introduction of new modes of production and the modernization of infrastructures, the interaction between environmental variability and new institutional arrangements might have contributed to increase the vulnerability of peasants to famine. 相似文献
