Previous empirical financial studies have paid little attention to the role of diversification strategy on financial choices. This study analyses the financing strategies of multibusiness firms, suggesting the relevance of sorting the diversification phenomena into its related and unrelated components. The implications of our findings are important because they explain earlier contradictory results on capital‐structure determinants and offer an explanation of how the degree of product specialization/diversification and the direction of diversification (related or unrelated) translate into different corporate financial behaviours. 相似文献

By improving the procurement process purchasing departments are becoming more and more strategic in order to increase overall companies performances. In the last years, web-based tools have effectively supported this trend by offering to buyers useful tools in order to help their activities. Purchasing departments have now to choose the right tool for the right purchase in the right supply market; for this reason it is important for them to adopt a portfolio approach exploiting all the different solutions offered by the technology according to the different situations.In this perspective, this paper identifies four most common purchasing approaches adopted by companies, which drivers are considered to choose among these, and which level of performances companies achieve through the identified approaches.Empirical evidence is based on a survey research involving 162 US companies. 相似文献

The aim of this paper is to analyze the impact that environment‐friendly and management‐quality improvements have on the firm's competitiveness (profitability and market share) within the fresh fruit and vegetable sector. Andalusian farming/marketing entities (producer organizations) serve as a reference for our analysis. For these entities, there are subsidy programs aimed at developing quality and environmental practices. Such programs are a top priority for the CAP's Common Market Organizations. An analysis of a simultaneous equations model is suggested, considering the distinguishing effect of quality‐environmental investment and the possible endogeneity problems among the variables. The results show a positive correlation between the application of the aforementioned activities and the competitiveness of the horticultural firms. L'objectif de ce travail c'est d'analyser l'impact des pratiques de production favorables à l'environnement ainsi que de la gestion de la qualité (rentabilité et part du marché) par rapport aux secteurs des fruits et légumes frais. Les organismes de commercialisation agricole d'Andalousie (organ‐ismes de production) représentent un point de référence pour notre analyse. Ces organismes bénéficient de programs d'aide au développement de la qualité et des pratiques favorables à l'environnement. Ces pro‐grammes constituent une priorité majeure pour les Organisations du Marché Commun dans le cadre des Politiques Agricoles Communes (PAC). Nous proposons ici une analyse d'un modèle aux équations simul‐tanées considérant l'effet caractéristique d'un investissement de qualité de l'environnement ainsi que les possibles problèmes à caractère endogène parmi les variables. Le résultat met en évidence une corrélation positive entre l'application des activités précédemment citées et la compétitivité des entreprises horticoles. 相似文献

We analyse the degree of polarisation in the international distribution of CO2 emissions per capita in the European Union. It is analytically relevant to examine the degree of instability inherent to a distribution and, in the analysed case, the likelihood that the distribution and its evolution will increase or decrease the chances of reaching an agreement on climate policy. Two approaches were used to measure polarisation: the endogenous approach, in which countries are grouped according to their similarity in terms of emissions, and the exogenous approach, in which countries are grouped geographically. Our findings indicate a clear decrease in polarisation since the mid-1990s, which can essentially be explained by the fact that the different groups have converged (i.e. antagonism among the CO2 emitters has decreased) as the contribution of energy intensity to between-group differences has decreased. This lower degree of polarisation in CO2 distribution suggests a situation more conducive to the possibility of reaching EU-wide agreements on the mitigation of CO2 emissions. 相似文献

The aim of this paper is to analyse the relationship between environmental and economic performance from the resource-based
theory within firms of the fresh fruit and vegetables sector. This study considers that the adoption of environment-friendly
practices has a greater influence on firms’ opportunities and abilities in the agricultural sector than in manufacturing sectors
and leads to closer links between performance variables. The reference for this empirical analysis is a panel data of horticultural
farming-marketing firms in Spain. The voluntary environmental programmes and the heterogeneity of their application lead us
to regard acquiring a competitive advantage as a relevant driver to improve environmental performance in this sector. A simultaneous
equations model is suggested reflecting the differential environmental effect and the assumption of endogeneity among variables.
The results show a positive impact of environmental differentiation on profitability and market share, also suggesting that
the perception of this positive experience implies greater environmental performance.

The object of the present article is to offer a decomposition of productivity indices incorporating environmental changes. The model followed is an input oriented approach related to undesirable output (environmental performance attribute) in horticultural marketing cooperatives. This study is motivated by both the lack of analysis of environmental performance's effects on agribusiness productivity and the relevance of cooperative firms in the European agricultural model for attaining sustainability. For this purpose, bootstrapped envelopment analysis is applied and the best practice frontier obtained corresponds to decision making units showing the best environmental behaviour. The Malmquist total factor productivity (TFP) is decomposed into technological change, efficiency and environmental change. In the second stage, the correlations of these changes with other management variables of cooperatives are analysed. The indicators obtained, on one hand, advice about the nonseparable distance function estimations when the environmental factor is introduced. On the other hand, the results display a relevant increase in efficiency and environmental components for the period under study showing a high influence from labour qualification, environmental effort and spillover effect in the sector. 相似文献

This paper deals with a fundamental subject that has seldom been addressed in recent years, that of market impact in the options market. Our analysis is based on a proprietary database of metaorders—large orders that are split into smaller pieces before being sent to the market—on one of the main Asian markets. In line with our previous work on the equity market [Said, E., Bel Hadj Ayed, A., Husson, A. and Abergel, F., Market impact: A systematic study of limit orders. Mark. Microstruct. Liq., 2018, 3(3&4), 1850008.], we propose an algorithmic approach to identify metaorders, based on some implied volatility parameters, the at the money forward volatility and at the money forward skew. In both cases, we obtain results similar to the now well-understood equity market: Square-Root Law, Fair Pricing Condition and Market Impact Dynamics. 相似文献
