The paper sets up a model of a multinational firm in which the home country uses a credit with deferral or an exemption system and the host country is a low-tax jurisdiction. In this model the impact of anti-tax-avoidance provisions on the size and the growth of the foreign subsidiary is analyzed. Two main results emerge. First, anti-tax-avoidance provisions may lower the cost of capital of foreign firms quite significantly. Second, in contrast to previous models with limited financial possibilities the paper shows that a tax induced growth dynamics is absent if there are some important tax constellations. 相似文献

When designing effective voluntary vaccination strategies against animal disease epidemics, policy-makers need to take into account that different groups of farmers base their participation decisions on different considerations. Using the past Bluetongue virus serotype 8 epidemic of 2006–2009 in Europe as an example, this paper uses the Reasoned Action Approach to identify a set of attitudinal beliefs being the major drivers behind the intended decision to participate in voluntary vaccination. The results show that there is heterogeneity among farmers in these beliefs. In particular, perceived risk, which was captured by a risk attitude and a risk perception of the farmer, and personality traits are associated with variability in beliefs about vaccination against Bluetongue. The patterns found between perceived risk, personality traits and other farm and farmer characteristics were discussed in relation to the governance of animal health. 相似文献

This article develops a method for using input–output data to calculate a farm share estimate for all food rather than the typical approach of estimating a price spread for an individual product. The farm share of the food dollar is approximately 14% in the United States and 17% in Canada. The farm share increased somewhat during the commodity price boom but has generally fallen steadily by approximately 20% since 1997. While the farm share of expenditures on food for home consumption is approximately 22% across both countries, it is 4% in the United States and 7% in Canada for meals consumed away from home. The empirical framework can be extended to other countries given the extensive use of System of National Account data making international and temporal comparisons possible across farm and food marketing systems. 相似文献

We introduce the concept "excess capital capacity" and employ a stochastic input requirement frontier to measure excess capital capacity in agricultural production. We also propose a two-step estimation method that allows endogenous regressors in stochastic frontier models. The first step uses generalized method of moments to get consistent estimates of the frontier parameters in the presence of endogenous regressors. The second step uses maximum likelihood to measure excess capital capacity and evaluate the factors that influence it. The empirical application to Dutch cash crop farms found varying degrees of excess capital capacity. The policy implications of excess capital capacity are discussed. 相似文献

This article examines the presence of spatial spillovers in farms’ dynamic technical inefficiency scores using Data Envelopment Analysis and a second-stage spatial truncated bootstrap regression model. Dynamic inefficiency is measured in terms of variable input contraction and gross investment expansion, while the second-stage model allows an individual’s dynamic inefficiency to be influenced by both own and neighbours’ characteristics. The empirical application focuses on the panel data of specialised Dutch dairy farms observed over the period 2009–2016 and for which exact geographical coordinates of latitude and longitude are available. The results confirm the existence of spatial spillovers in farmers’ dynamic technical inefficiency levels. Although changes in neighbours’ subsidies do not significantly influence an individual’s inefficiency, an increase in neighbours’ age reduces an individual’s performance, while an increase in neighbours’ levels of intensification improves an individual’s dynamic efficiency. 相似文献

The dumping of milk, the offering of hospitality size goods in grocery stores, and the closure of processing facilities are examples of the disruptions caused by the pandemic to the dairy, poultry, and egg sectors. These supply management sectors, however, are more resilient to the impacts of COVID-19 than other sectors as producers are generally more financially stable, losses are pooled, and production/marketing efforts are coordinated. 相似文献

The Economics of Controlling Infectious Diseases on Dairy Farms 总被引:1,自引:0,他引:1

Cost‐effective disease control on the dairy farm can enhance productivity and subsequently profitability. Previous economic studies on animal disease have focused on production losses and evaluation of disease eradication programs and have provided little guidance on the optimal prevention action. This paper presents a theoretical model on the economics of livestock disease and develops an empirical model to determine the optimal set of control strategies for four production‐limiting cattle diseases: bovine viral diarrhea (BVD), enzootic bovine leukosis (EBL), Johne's Disease (JD) and neosporosis. Control functions indicating the prevalence of infection with each of the four diseases for each of the 10 strategies are estimated. The optimal strategies that minimize total disease cost (direct production losses and control expenditures) are provided for each disease on the basis of farm survey results from the maritime provinces. The results emphasize the importance of introduction checks before new animals enter the herd and adequate vaccination protection as cost‐effective control strategies. Lutter contre la maladie d'une manière rentable dans les élevages de bovins laitiers peut déboucher sur un meilleur rendement et des profits plus élevés. Les études économiques antérieures s'intéressant à cet aspect portaient essentiellement sur les pertes de production et l'évaluation des programmes d'éradication. Elles donnaient peu d'indications sur la solution idéale au niveau de la prévention. Cet article présente un modèle théorique de l'économique des maladies du bétail et aboutit à un modèle empirique permettant d'établir le jeu optimal de moyens pour lutter contre quatre maladies réduisant la production animale : la diarrhée à virus des bovins (DVB), la leucose bovine enzootique (LBE), la paratuberculose et la néosporose. Les auteurs estiment les fonctions qui indiquent la prévalence d'une infection pour chacune des quatre maladies retenues, dans le cadre des dix stratégies examinées. Ensuite, ils présentent les meilleures stratégies, à savoir celles qui minimisent le coût total de la maladie (pertes de production directes et dépenses associées à la lutte contre la maladie), pour chaque maladie en fonction des résultats d'un sondage auprès des éleveurs des provinces de l'Atlantique. Tout indique que les méthodes de lutte les plus rentables sont l'examen de l'animal avant son addition au troupeau et une vaccination qui protègera les bêtes de manière adéquate. 相似文献

This article explores the reasons for differences in female rural–urban participation rates by estimating a dynamic model of participation allowing for unobserved heterogeneity and state dependence using Canadian panel data. The results suggest that overall observed differences in rural–urban participation rates are primarily due to differences in observed socioeconomic characteristics. However, for women resident in low-income households, there is evidence that the operation of rural labor markets effectively lowers their participation rates. 相似文献

Proze?orientiertes Controlling erlaubt eine umfassende, differenzierte und zielgerichtete Steuerung des Produktionsprozesses. Besondere Bedeutung kommen dabei der Beachtung der Controllingkriterien vor einer Entscheidung sowie dem Forward-Controlling zu. Abh?ngig vom Produktionstyp ist das Controllinginstrumentarium unterschiedlich zu gestalten. W?hrend für die Einzelfertigung Kostenkriterien im Vordergrund stehen, stellen für die Serien-/Proze?fertigung Ressourcen, Termine und die internen und externen Qualit?tsfaktoren die wesentlichen Controllingkriterien dar. 相似文献
