Residents' perceptions on tourism impacts   总被引:14,自引:0,他引:14  
The limited explanatory research on residents' perceptions of tourism impacts has resulted in an underdeveloped theoretical orientation of research on this subject. This paper presents a social exchange process model as a theoretical basis for some understanding of why residents perceive tourism impacts positively or negatively. The model is based upon the concept of the exchange relation. Propositions are derived from the model to test the relationships between the model's components. These propositions have been developed from inferences based upon the social exchange literature.  相似文献

This study estimated demand functions for tourism by U.S. residents in Mexico border areas, the Mexican interior, and overseas. There was no evidence that U.S. tourists substitute Mexico for more distant destinations as transportation costs rise. Border tourism is income elastic when the share of U.S. income of the border states is held fixed. Tourism in the Mexican interior is also income elastic. Tourism along the border is price elastic, while tourism in the interior is elastic with respect to U.S. and overseas prices but inelastic with respect to Mexican prices. The rise in the share of the Mexican interior in U.S. overseas tourism is not related to price factors. Recent devaluations of the Mexican peso are unlikely to provide benefits to the Mexican tourism industry.  相似文献

The experiences of managers who continue to work through a labour stoppage is a largely overlooked question in industrial relations research and practice. Qualitative long interviews were conducted with managers who worked through a strike. A shared narrative for managers' strike experiences emerged. Managers perceived that their prestrike workplace was cooperative and characterized by positive labour‐management relationships. The strike was experienced as contentious and personalized with managers reporting that they and their families were targets of aggression from strikers. The managers envisioned a more formal poststrike workplace characterized by less collegial labour‐management interactions. We discuss the implications of these findings and call for further research on managers' experiences of industrial relations events. Copyright © 2014 ASAC.

Theory holds that knowledge has positive economic consequences. While US corporations defend record high level cash holdings citing the precautionary motive in response to changing firm characteristics, I find that knowledge‐based innovation can partially explain these changes. Using distance to the nearest research university as a measure of knowledge intensity, I show that knowledge‐intensive firms hold more cash, even after controlling for firm R&D. Moreover, knowledge‐intensive firms exhibit higher marginal value of cash and save more cash from cash flows than their less knowledge‐intensive counterparts. Overall, the precautionary motive appears to dominate the agency motive, with the effect of knowledge on cash holdings strengthening over time. Copyright © 2014 ASAC.

This study considers the effect of freezing defined benefit pension funds on shareholder risk and returns. The conditional models used in this study directly assess the effects of a pension fund freeze on returns and on systematic and residual risk. While pension fund freezes do not significantly affect performance or systematic risk, they do significantly reduce short‐term residual risk. Pension fund freezes therefore do not generally present significant financial advantages to shareholders. Only shareholders of firms with pension funds in crisis would benefit from significant systematic risk reductions. Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.  相似文献

Multiperiod linear programming techniques are used to evaluate comparative profitabilities and soil erosion rates for corn grown monoculturally and in rotation with a) soybeans, b) soybeans and oats, c) barley, and d) alfalfa on moderately sloping land with medium loam soils in southern Ontario. Attention is focussed on the case of a highly leveraged recent entrant to farming with heavy debt servicing needs and potential cash flow constraints. Monocultural corn was found to be more profitable than any of the rotational systems, with corn-soybeans rotations the next most profitable and corn-barley rotations the least profitable. Corn-soybeans caused the highest soil erosion, followed by continuous corn, with corn-alfalfa rotations causing the least. Les techniques de programmation linéaire multipériode sont utilisées pour évaluer et comparer les niveaux de profit et les taux d' érosion de sols agricoles moyennement argileux pour des systèmes de production de grandees cultyres localiées dans le sud de l' ontario et produisant, soit du mais en régime de monoculture, soit du mais en rotation avec: a) du soja, b) soja et avoine, c) orge. et d) de la luzerne plantée sur des terrains à pentes modérées. L' analyse developpée dans cet article met l' accent sur des agriculteurs récemment installés, disposant de beaucoup d' actifs, mais également, ayant des besoins énormes d' emprunts et, par conséquent, soumis à des contraintes potentielles sur leurs cash-flows. Les résultats obtenus montrent que le système de production, mais-monoculture, est le plus viable de tous les systèmes etudies. Parmi les systemes de production reposant sur une rotation culturale, il s' avère que celui combinant maïs et soja vienne en seconde position, tandis que un régime cultural fondé sur une rotation maïs et orge donne les pires resultats. Pour ce qui concerne des taux d' erosion des sols, la rotation maïs-soja cause les plus gros dommages. ensuite suivie par le système de production, maïs-monoculture. Finalement, les taux d' erosion les plus faibles ont été obtenus pour la rotation culturale, maïs-luzerne.  相似文献

Haiti, with a forest cover estimated at 3% of all land area, has experienced severe degradation of its natural resources and a significant change in its land cover. While deforestation in Haiti is obviously multifaceted, one issue emerges from previous empirical analysis in explaining deforestation: land tenure. This study focuses on the causes of deforestation in Haiti, particularly in Forêt des Pins Reserve, using the annual average area of cleared forest per household as the dependent variable. Data were collected with the use of a survey instrument administered to 243 farm households in 15 villages inside the Reserve. Tobit Regression results reveal that household size, education of head of the household, land tenure regime, and farm labor are important factors affecting land clearing.  相似文献

For a number of reasons, the pricing of fluid milk in Canada is not subject to the rigors of the market. Given this, questions arise as to the appropriate form of regulated pricing. An increasingly common method is the use of formulas. A large number of possible formulas exist and the main types are outlined in this paper. In addition, each is evaluated in terms of a set of objectives and operational criteria, and a format for establishing a preferred pricing system is suggested.
Pour plusieurs raisons la fixation du prix du lait fluide au Canada n'est pas sujette aux rigueurs du marché. Étant donné cette situation, des questions se présentent quant à la methode fixer le prix du lait fluide. line méthode de plus en plus courante d'utiliser une formule. Un grand nombre deformulespossibles existe, et les differentes sortes sont exposées dans cet article. Cet article suggère la sorte de formule qui établira des prix qui satisfont l'intérél public comme les agences régulatrices le définissent. Ensuite, des formules canadiennes courantes sont comparées à une telle formule.  相似文献

Dr. PC is a 50–80‐minute, in‐class management control case. The case asks students to develop a management control system for a small computer repair business. Informed initially by personal experiences, and then from viewing a consumer affairs video that depicts an employee repeatedly violating his firm’s code of conduct, students work together to outline key management controls. After viewing the video and discussing key management controls, students are then exposed to Simons’s levers of control framework and asked to develop a comprehensive management control system for the small business. The case was developed over three years with the help of 344 undergraduate, master’s, and executive students. Student feedback from earlier versions of the case indicates they found the case stimulating and effective at reaching its learning objectives of understanding the purpose of and how to design a management control system for a small business.  相似文献

This paper analyzes the responsiveness of the U.S. meal and poultry economy to government policies and other exogenous shocks. In particular, it focuses on the measurement of changes to consumer welfare. An explicit econometric model represents the supply of fed beef, non-fed beef, pork, and poultry. The interaction between the livestock and feed grain markets is captured by an econometric model of the supply and demand for corn. Consumers are represented by a complete system of consumer demand equations. The model is used for a partial analysis of the welfare effects of an actual agricultural policy decision – the sale of large quantities of grains to the Soviet Union in the third quarter of 1972. The loss to consumers that is attributable to the increased grain exports did not reach its maximum until the second quarter of 1975. It is estimated that from 1973 to 1975 consumers suffered a reduction of meat consumption that they valued at $4.5 billion (U.S.). Furthermore, the effects of grain exports proved far larger than the losses due to the poor harvests of 1973 and 1974. Finally, attempts to shelter consumers from the effects of the increased corn exports, either by increased beef imports or increased grain price supports, would have had little success in compensating for the welfare loss actually suffered. Ce papier fail ?analvse de la réponse des secleurs de ?économie quant au bétail et à la volatile aux Flats-Unis, leur reponse à la politique gouvernementale et à?aulres coups exterieurs. En particulier, ce papier se concentre sur la mésure des changements au bien-étre des consommateurs. Un modèle économélrique qui est explicite représente ?approvisionnement du boeuf brouiè, du boeuf non-broutè, du pore el de la volatile. Lcar;action réciproque entre le marché de bélail et ie marché de grains est monlré par un modèle economelrique de ?offre et de la demande pour mats. Un système des équations représente la demande des consommateurs. On utilise le modèle pour ohtenir une analyse parlielle des effeis en ce qui concerne le bien-étre des consommateurs par suite ?une décision faite ?une politique agricole – celle de la vente de grandes quantités de grains à?Union soviétique au troisième quartier de ?année 1972. Laperte aux consommateurs qui est imputable aux exportations augmentées de grain n'apas alteinl son maximum jusqu'au deuxième quartier de 1975. On a eslimé que de 1973 à 1975 les consommateurs ont essuyé une réduction de la consommation de viande qu'ils ont evaluée à$4.5 milliard (en dollars des Etats-Unis). En outre, les effeis des exponations de grain se sont révélés bien grands que les effets des moissons maigres de 1973 el 1974. Finalement, des efforts de protéger les consommateurs contre les effets des exportations augmentees de maìs, ou par des importations augmentees de boeufou par augmenter le soutien pour le prix du grain auraient eu peu de succès à remplacer les pertes en fait essuyées.  相似文献
