We examine causality and efficiency in the Italian T-bond market, where cash trades take place on the domestic Mercato Telematico dei Titoli di Stato, while futures trading is based on the London International Financial Futures Exchange. We find evidence that causality in prices runs in both directions, and that the cash lead is almost comparable in size and extension to the futures lead. We then try to assess whether the cash market is weak-form efficient with respect to LIFFE prices. Using a simple trading rule with a variety of time and price filters, we conclude that the observed lead cannot be exploited to make a profit after transaction costs.  相似文献

The understanding of the determinant factors of customer purchase intention is necessary, and it is equally important to study the online purchase context, since this context is disseminated among customers. A theoretical model has been elaborated on and tested, considering the constructs of information quality, distrust, and perceived risk as antecedents of purchase intention, and aiming to analyze the relationship among these constructs in the online purchase context. A quantitative research study has been performed by means of the application of a survey. Multivariate statistics techniques have been applied for data analyses, including structural equation modeling. This study contributes to the evolution of the empirically tested concepts by providing a greater individual understanding of each construct presented in the theoretical model, as well as the relationship among them as determinants of purchase intention; the indication is that meaningful relationships were found which may impact greater profitability and, consequently, greater competition for online retailers.  相似文献

The literature on stochastic input–output (I–O) analysis has paid considerable attention to the bias in the Leontief inverse. This paper extends previous studies by assuming supply and use tables (SUTs rather than I–O tables or input coefficients matrices) to be stochastic. This is a natural starting point because SUTs have become the basic data sources for I–O applications. In a Monte Carlo simulation experiment, a given SUT is randomized in two different ways and the effects are determined for eight different multiplier matrices. The analysis is carried out for Spain, Italy, the Netherlands, Germany and Finland, using their SUTs for 2006. The findings indicate that, in general, biases are statistically significant but negligibly small. This corroborates earlier findings obtained for stochastic I–O tables.  相似文献

Currently there is ample discussion among EU Institutions (European Commission, European Parliament, and Member States' governments) on the opportunity for setting up a comprehensive EU‐wide framework on risk and crises in agriculture. In the meantime, within the limits of the WTO rules on agriculture, national governments are allowed to intervene through direct compensation to farmers in case of exceptional events that cause damages to farming operations and through subsidies to crop insurance programs. Such schemes are quite expensive for domestic budgets and some Member States are trying to switch some of their cost to the Community's budget, although an expansion of financial resources devoted to agriculture in Europe is rather unlikely. Moving from the recently emanated proposal of the European Commission, this paper discusses the main issues related to public intervention for risk and crises management in agriculture. Actuellement, les institutions européennes (Commission européenne, Parlement européen et gouvernements des pays membres) discutent intensément de l'opportunité d'élaborer un cadre général pour l'ensemble de l'Union européenne sur les crises et les risques dans le secteur agricole. Entre‐temps, selon les règles de l'OMC sur l'agriculture, les gouvernements nationaux peuvent intervenir en accordant des compensations financières directes aux agriculteurs en cas de circonstances exceptionnelles causant des dommages aux exploitations agricoles ainsi que des subventions aux programmes d'assurance récolte. Ces interventions amputent considérablement les budgets nationaux, et certains pays membres tentent de transférer une partie de leurs coûts au budget de l'Union européenne, bien qu'il soit peu probable que les ressources financières consacrées à l'agriculture en Europe augmentent. A la lumière de la récente proposition de la Commission européenne, le présent article traite des principaux thèmes liés à l'intervention publique dans la gestion des risques et des crises dans le secteur agricole.  相似文献

Social and organizational capital: Building the context for innovation   总被引:2,自引:0,他引:2  
In the light of the key role intellectual capital has for firms' innovation capability, this paper analyzes the influence of two of their dimensions, organizational capital and social capital, on firms' product innovation, and the moderating role of radicalness. Unlike previous studies, the unit of analysis will not be the firm, but the R&D department. Thus, our research, conducted with a sample of Spanish industrial companies, provides a new insight with interesting results. First, our findings show that social capital favours firms' product innovation, especially under radical innovations. Second, organizational capital has an indirect effect on product innovation through positive influence on social capital. This implies that firms can stimulate communication and interaction among people, and therefore innovative activity, by means of explicit and codified knowledge (organizational capital).  相似文献

Abstract. This paper contributes to the growing literature that analyses the Spanish publishing performance in Economics throughout the 1990s. Several bibliometric indicators are used in order to provide Spanish rankings (of both institutions and individual authors) based on Econlit journals. Further, lists of the ten most influential authors and articles over that period, in terms of citations, are reported. We are grateful to many colleagues who made very useful remarks to preliminary versions of this paper, as well as to two anonymous referees. We are particularly indebted to Xavier Sala-i-Martín, without whose invaluable help this work would not have been possible. All errors or omissions are of our exclusive responsibility.  相似文献

This article reports exploratory research about tendencies toward postmaterialism in university students. This paper used the theoretical framework proposed by Inglehart regarding three categories of leisure: postmaterialist, materialist and common. Students from a Spanish university (N = 1036) completed questionnaires that evaluated their materialist-postmaterialist values, how often they practiced the activities included in each category of leisure and the motivational factors involved in them. The results revealed that university students showed a tendency toward postmaterialism. Further, relationships were found between materialist-postmaterialist values and categories of leisure. This study results suggested that the tendency toward postmaterialist values may be a factor in structuring the leisure patterns of young Spanish university students.  相似文献

Two decades into the most recent wave of regionalism many of its implications remain to be fully understood. A vast literature has explored the impacts of free trade agreements (FTAs) on investment flows, but less attention has been given to how existing patterns of investment alter FTA liberalisation. It is contended here that the dynamic interplay between overlapping FTA areas and the investment sunk in them shapes governments' and firms' positions regarding further FTA liberalisation. During trade negotiations, a country may decide to exclude a sector from FTA liberalisation to prevent (concession prevention) future FTA partners from making similar demands. Concession prevention could also occur when a foreign firm, holding a dominant market position in a host country, relinquishes liberalisation demands in an FTA between host and home countries to prevent its current position being eroded if the host country grants similar (or better) concessions to competing firms from other countries in future FTAs. Conversely, investment sunk into a country's sensitive sector in the territory of partners from previous FTAs could pre‐empt (concession pre‐emption) the protectionist position of that country when it subsequently negotiates FTAs with the investment‐source countries. These arguments were tested in the negotiations around the liberalisation of the automotive industry that Thailand and Malaysia had with Japan in their respective bilateral FTAs. The distinct interaction between investment and the FTAs in which these countries participate resulted either in entrenchment of protectionism in the sector or its liberalisation across subsequent FTAs.  相似文献

From a psychosocial perspective, we have attempted to identify the characteristics of the democratic systems of a sample of 36 Andalusian cooperatives of associated workers. In this study it has become evident that those who participate the least in the governments of their organizations are the workers and those with less education. Thus, there is a high degree of association between participation in the governing of the cooperative and the development within it of an appropriate organizational culture. The results of this study have allowed us to empirically deconstruct the concept of cooperative democracy, and this process may have an effect on the improvement of human resource administration in this type of organization.  相似文献

We investigate the political determinants of liberalization in OECD network industries, performing a panel estimation over 30 years, through the largest and most updated sample available. Our results contrast with the traditional wisdom according to which right-wing governments do promote market-oriented policies more intensively than left-wing ones. Our findings reveal a neglected role of the so-called neoliberalism in promoting left-wing market-oriented policy. As a result, we claim that ideological cleavages ceased to act as determinants of the liberalization wave observed in network industries. This result is confirmed when controlling for the existing regulatory conditions that executives find when elected. Furthermore, we find that the country’s exposure to other countries’ policy initiatives acts as a positive stimulus for liberalization policies.  相似文献
