Good Agricultural Practices (GAPs) are aimed at reducing farm level microbial contamination of fresh produce and include both fixed and variable cost components. We empirically analyze three scenarios of voluntary food safety practice adoption and third‐party certification in the North American fresh strawberry market using a spatial equilibrium model. The model incorporates GAPs adoption across production regions and across farm size. Transportation and product shrinkage, which are critical factors in inter‐regional trade of perishable products, are also included. Regional trade pattern impacts are assessed and used to draw inferences for pressure on market structure. Results indicate that competitive pressures are greatest on those regions with mid‐size volumes that are not able to take advantage of close market proximity, yet still must absorb additional costs. This suggests that adoption of food safety practices, even if voluntary, is likely to accelerate what is already a bi‐modal structure for this industry. Les bonnes pratiques agricoles (BPA) visent à réduire la contamination microbienne des produits frais à la ferme et comprennent des coûts fixes et des coûts variables. Nous avons effectué, à l'aide d'un modèle d'équilibre spatial, l'analyse empirique de trois scénarios d'adoption volontaire de pratiques de sécurité alimentaire et de certification par un tiers dans le marché nord‐américain des fraises fraîches. Le modèle intègre l'adoption de BPA dans toutes les régions productrices et les fermes de toute taille. Le transport et le flétrissement, qui constituent des facteurs critiques dans le commerce interrégional des denrées périssables, ont aussi été inclus. Nous avons évalué les répercussions de la structure de commerce régional et les avons utilisées pour tirer des conclusions sur la pression exercée sur la structure de marché. Les résultats ont indiqué que les pressions concurrentielles étaient plus importantes sur les régions qui produisent des volumes moyens, qui ne peuvent tirer profit des marchés de proximité, mais qui doivent pourtant absorber des coûts additionnels. Ces résultats autorisent à penser que l'adoption, même volontaire, de pratiques de sécurité alimentaire contribuera probablement à accélérer ce que est déjà une structure bimodale de l'industrie.  相似文献

Agri-environmental contracts are used to provide incentives for nature management on private land in, e.g. the European Union. The aim of this article is to investigate preference heterogeneity for agri-environmental contracts among farmers in order to discuss potential policy improvements utilising heterogeneity. We used a choice experiment to elicit farmers’ stated preferences for afforestation contracts. Four attributes are investigated: purpose of afforestation, option of cancelling the contract, monitoring, and compensation level. All attributes present a potential conflict between farmers’ and authorities’ interests, which emphasises the importance of knowing how to handle these interests. A random parameter logit model shows that having the option to cancel the contract decreases farmers’ required compensation level and monitoring increases it. Furthermore, farmers are willing to accept a lower compensation when the aim is to protect biodiversity and ground water relative to recreation. Latent class models with class probability variables reveal discrete heterogeneity and support a division into four groups with divergent preferences. For example, a group of farmers who already have forest areas does not find the option of cancelling the contract important, whereas another group relying on the farm for income requires higher compensation. The findings indicate potential for efficiency gains from targeting the contracts.  相似文献

Development and validation of the hospitality emotional labor scale   总被引:3,自引:0,他引:3  
This paper describes the development and validation of a 19-item instrument (hospitality emotional labor scale, HELS) for assessing employees’ perception of emotional labor in hospitality organizations. Three studies were conducted to purify the scale items, examine the scale's dimensionality, and to evaluate the scale's reliability, factor structure, and validity. The internal consistency coefficients from the three studies, ranging from .69 to .88, evidence the reliability of the HELS. The paper concludes with a discussion of potential applications of the scale.  相似文献

Governments’ net assets balances are viewed as a measure of fiscal health and have been linked to municipal credit ratings. This study explores the extent to which ambient socioeconomic factors are captured in aggregated restricted and unrestricted net assets balances (termed “liquid net assets”) to understand why such balances are relevant to credit analysts and others. We model liquid net assets balances using observable nonaccounting factors (e.g., unemployment rates) to learn whether they reflect such influences. We use panel data for fiscal years 2007–2011 so our results comprehend effects of recent economic fluctuations. We find that liquid net assets balances impound a rich array of influences, bearing a positive association with the mayor‐council form of government, community wealth, the incidence of property crimes, and increases in governments’ business‐type net assets. Liquid net assets balances bear a negative association with liabilities for postemployment benefits, unemployment, and violent crime. The results indicate that net assets balances capture noteworthy debt burden, administrative, and socioeconomic influences and, as such, have meaning beyond their basic accounting interpretation.  相似文献

This paper estimates, using Bayesian and global VARs, the spillover effects of unconventional fiscal and monetary policies implemented in the United States and in the Eurozone during the last decade. Consumer confidence and investor sentiment indicators are introduced in the models in order to highlight the signalling channel in the responses to economic policy innovations in times of crisis. Our results reveal that consumer and investor perceptions of innovative economic measures are relevant to study the pass-through of economic policies to the real sector in times of crisis and zero lower bound interest rates. In particular, the signalling channel plays an important role in successful unconventional economic policies. Moreover, if unconventional economic policies have an impact abroad, the effects are similar to those measured in the domestic country/region. Consequently, coordination and transparency are a prerequisite for ensuring short-term growth after a global financial crisis.  相似文献

Means–end theory aims at explaining how consumers evaluate products by linking relevant attributes to perceived consequences to desired ends in a hierarchical way, based on core assumptions of cognitive psychology about human information processing. This study investigates the influence of affective states on information processing styles in a means–end measurement situation, thus taking into account an important antecedent and correlate of human decision making and behavior that has received scarce attention so far in the methodological literature on means–end chains. The results reveal that a person's affective state indeed influences the style of information processing. Respondents in a positive mood used more general knowledge structures and processed the laddering questionnaire faster than respondents in a negative or neutral mood. The laddering technique, which measures means–end chains, thus seems to be sensitive to situational effects, and this finding indicates that affective states then also might have an influence on product knowledge and the decision‐making process in a purchase situation. © 2004 Wiley Periodicals, Inc.  相似文献

Earnings predictability can affect investment decisions and stock prices. An important source of earnings forecasts for a wide variety of empirical studies has been the Value Line Investment Survey. The purpose of this study is to identify factors that consistently account for cross-sectional differences in Value Line earnings predict-ability. A multivariate model consisting of four company variables and a set of industry indicator variables is used to evaluate the intertemporal consistency of factors related to earnings predictability. Quarterly and annual forecasts are used to measure earnings forecast accuracy. The results by year indicate that one factor, earnings variability, is consistently related to earnings predict-ability.  相似文献

This article investigates the impact of European Central Bank policies on credits considering financial and banking fragmentation. Using European data from the past decade, we estimate SVAR models to analyze the regional impact of conventional and unconventional measures on price and volume indicators of fragmentation. The risk-taking channel is studied using GVAR models to document the national consequences of this fragmentation. We find that unconventional measures increase credit in peripheral countries. Monetary policies alleviate fragmentation, but mostly in terms of price dispersion rather than credit volume. Finally, unconventional measures imply a rebalancing of European bank assets in favor of foreign currency denominated-assets.  相似文献

We present a conceptual and operational framework for analysing financial disclosure management by charitable organisations. We paint an overall picture of the issue and apply various theories to explain this management practice. The framework lists the many motivations and contextual factors that impel managers of charitable organisations to manage financial information and explains how they weight and prioritise items in light of considerations such as incentive bonuses, social performance, resource dependence and monitoring mechanisms. The framework also sums up the strategies and techniques that undergird financial disclosure management and describes the monitoring mechanisms that mitigate this opportunistic practice and its consequences. The paper concludes by presenting several research avenues.  相似文献
