The purpose of this article is to model the interaction between the targets of the current Comman Agriculture Politic (CAP): environmental adaptation, subsidies, and efficiency of animal farming. To this end we first have to identify the production frontier and relative efficiency level for each animal‐oriented farm in the sample. The production frontier and efficiency index for each type of farm (assuming no specific production functions) are identified using Data Envelope Analysis (DEA) techniques. We then address the relationship between relative efficiency, farm size, and environmentally friendly behavior by carrying out a nonparametric regression of efficiency, on economic size, a proxy for the degree of environmental appropriateness, and regional dummies. Calculations of the efficiency of the farms including direct subsidies are compared with the counterfactual exercise in the case in which direct subsidies are not considered. Finally, we look for relations between subsidies and factors such as farm size, efficiency, and environmentally friendly behavior. One key result shows that, on average direct payments generally tend to increase efficiency. However, in most of the cases the mean efficiency decreases as the percentage of direct payments rises. Direct payments are found to be positively related to environmentally friendly production, at least in Germany. However, in general, the direct payment system is not sufficient to offset the fact that the less environmentally friendly farms as well as the larger farms are more efficient. 相似文献

In the past decade, some observers have noted an unusual aspect of the Mexican peso’s behavior: During periods when the U.S. dollar has risen (fallen) against other major currencies such as the euro, the peso has risen (fallen) against the dollar. Very few other currencies display this behavior. In this paper, we attempt to explain the unusual pattern of the peso’s correlation with the dollar by developing some general empirical models of exchange rate correlations. Based on a study of 29 currencies, we find that most of the cross-country variation in exchange rate correlations with the dollar and the euro can be explained by just a few variables. First, a country’s currency is more likely to rise against the dollar as the dollar rises against the euro, the closer it is to the United States and the farther it is from the euro area. In this result, distance likely proxies for the role of economic integration in affecting exchange rate correlations. Second, a country’s currency is more likely to exhibit this unusual pattern when its sovereign credit rating is more risky. This may reflect that currencies of riskier countries are less substitutable in investor portfolios than those of better-rated countries. All told, these factors well explain the peso’s unusual behavior, as Mexico both is very close to the United States and has a lower credit rating than most industrial economies. 相似文献

The aim of this paper is to contribute to the knowledge of strategic factors that explain the competitive position reached by firms in their activity sector. We have used a survey carried out in 1999 on 287 executives that belong to the service sector in the province of Santa Cruz de Tenerife. We have analysed the differential factors that distinguish the strategic performance of competitive vis‐à‐vis non‐competitive firms, by jointly assessing the variables representative of the sector (five competitive forces defined by Porter) and variables of an internal feature. Finally, we have moved the level of analysis from the industry to the firm; specifically, we have focused on managerial capabilities due to the significant role played by managers in the strategic decision‐making process. The use of cluster analysis to classify firms depending on their degree of competitiveness and the application of the See5 induction algorithm of rules and decision trees to determine the differential factors that distinguish competitive from non‐competitive firms, provide a methodological framework for the most significant contributions of this work.

Protection and Trade in Services: A Survey 总被引:5,自引:0,他引:5
This paper surveys the literature on trade in services, focusing on the policies that are used to restrict such trade, the gains from liberalization, and the institutional mechanisms that have been adopted in the pursuit of liberalization. The paper argues that technological progress and international trade negotiations are likely to keep liberalization of trade in services a high profile policy issue. It also suggests that the research agenda should focus on developing better estimates of the welfare costs of protectionism in the service sector. 相似文献

The current work represents a piece of research on the family firm of the semasiological, interpretive or culture creation
type. In it we carry out a comparative analysis of the organizational culture of this type of firm along with firms not considered
to be family firms, using as theoretical framework generally accepted theories in business administration, such as the systems,
neoinstitutional, transformational leadership, and social identity theories. Our findings confirm the existence of certain
elements of culture, especially values and allow us to propose a value-based model to help family firms to survive through
different family generations. 相似文献

Zusammenfassung Ein einfaches keynesianisches Modell der Inflation und der Arbeitslosigkeit bei rationalen Erwartungen. — Dieser Aufsatz entwickelt
ein einfaches makro?konomisches Modell keynesianischer Struktur, in dem eine lang-same Anpassung der Nominall?hne das gleichzeitige
Bestehen von Inflation und Arbeitslosigkeit zul?βt. Die Preise der Fertigwaren sind vollst?ndig flexibel, und die Erwartungen
hinsichtlich der zukünftigen Preisbewegungen werden rational ge-bildet, so daβ sie alle Informationen über institutionelle
Beschr?nkungen des Arbeits-marktes und über die w?hrungs- und fiskalpolitischen Regeln der Regierung ent-halten. Es wird gezeigt,
daβ es trotz kurzfristiger Starrheit der L?hne m?glich ist, die Volkswirtschaft sofort bei Zielgr?βen für Inflation und Besch?ftigung
zu stabili-sieren, wenn man die Maβnahmen so kombiniert, wie R. Mundell (1971) vorgeschla-gen hat, d.h. die Rate der monet?ren
Expansion sollte sich nach der angestrebten Inflationsrate richten und die Fiskalpolitik dem Besch?ftigungsziel dienen.
Résumé Un simple modèle Keynesien d’inflation et de ch?mage sous des expectatives rationelles. — Ce papier développe un simple modèle macroéconomique de la structure Keynesienne où l’ajustement lent des rémunérations nominales permet la coexistence de l’inflation et du ch?mage. Les prix des biens finaux sont complètement flexibles et les expectatives concernant les mouvements futurs des prix sont formées rationellement en manière qu’elles incorporent toutes les informations regardant les restrictions institutionelles sur le marché du travail aussi bien que les règles de la politique monétaire et fiscale du gouvernement. Nous démontrons que, malgré de la rigidité salariale à court terme il est possible de stabiliser immédiatement l’économie sur le niveau des buts d’inflation et de ch?mage supposé que la combinaison des politiques recommandée par R. Mundell ({dy1971}) soit pour-suivie, c’est-à-dire que le taux de l’expansión monétaire devrait être lié au but d’inflation et la politique fiscale au but de ch?mage.
Resumen Un modelo keynesiano simple de inflación y desempleo bajo expec-tativas racionales. — En este artículo se desarrolla un modelo macroeconómico simple de una estrutura keynesiana, donde un ajuste lento de los salarios nominales permite la coexistencia de inflación y desempleo. Los precios de los bienes finales son completamente flexibles y las expectativas referentes a movimientos futuros de precios se forman racionalmente, de tal manera que ellas incorporan toda la información referente a limitaciones institucionales en el mercado del trabajo, como también las reglas gubernamentales de las políticas monetaria y fiscal. Se muestra, que a pesar de la rigidez de corto plazo de los salarios, es posible estabilizar instan-tàneamente la economia a niveles establecidos como metas para la inflación y el desempleo, siempre que se aplique la mezcla de politicas recomendada por R. Mundell (1971), p.ej.: la tasa de expansión monetaria debe ser ajustada a la tasa de inflación asignada como meta y la política fiscal a la tasa de desempleo asignada como meta.相似文献

Most empirical research on e-procurement has focused on large economies and technology-related industries, paying little attention to smaller economies and traditional industries. This paper addresses this gap by presenting a study on the state and development of e-procurement in the Greek food and drink industry, based on four case studies with some of the largest organisations in the industry. This study indicates that the uptake of e-procurement has been slow and reveals some important impediments, such as the uncertainty of the technology and its benefits, the lack of infrastructure and skills and the traditional nature of the industry. These results led to a series of findings, propositions for further investigation. The drivers and impediments to e-procurement have been classified into four different levels: global, country, industry and firm. Each of these levels requires a different approach to dealing with it, having implications for practitioners and policymakers. 相似文献
