The Economic Forces Driving Food Safety Quality in Meat and Poultry   总被引:1,自引:0,他引:1  
This article examines the impact of regulation and market-driven private actions on food safety performance in the meat and poultry industries. We find that private actions account for about 80% and regulation about 20% of the overall reduction in the share of samples of cattle and hog carcasses, ground beef, and broilers testing positive for Salmonella if all regulation and private actions were increased by identical amounts.  相似文献

Residential lawns provide diverse benefits, including social (e.g., enhancing humans’ physical and psychological well‐being), economic (e.g., increasing real estate values), and environmental (e.g., supporting local ecosystems) benefits. However, improper lawn fertilizer applications can cause adverse environmental consequences, such as excessive chemical runoff into adjoining watersheds leading to water contamination. Currently, the importance of eco‐friendly fertilizers to homeowners has not been assessed. This study uses a discrete choice experiment to test whether eco‐friendly fertilizer attributes influence homeowners’ preferences for sustainable landscape management. The findings show that eco‐friendly fertilizer attributes positively influence homeowners’ preferences and willingness to pay, supporting the premise that the promotion of eco‐friendly fertilizer features could improve local ecosystems through increased adaptation. Furthermore, this study tests whether certain fertilizer attributes influence homeowners’ preferences in states with and without fertilizer restrictions. Since the regulatory environment affects homeowners’ preferences for sustainable landscaping, this study compares the results between regulated and unregulated states. The findings reveal that homeowners are more likely to use and are willing to pay higher premiums for sustainable fertilizers in states with residential fertilization regulations. This suggests that with strict fertilizer ordinances, homeowners are more geared toward eco‐friendly landscaping options and that related educational programs should be made available. Les pelouses résidentielles offrent divers avantages, incluant les avantages sociaux (comme la valorisation du bien‐être physique et psychologique humain), économiques (comme la valeur immobilière), et environnementaux (comme l'appui des écosystèmes locaux). La mauvaise application des fertilisants a parfois des conséquences environnementales négatives comme le ruissellement chimique excessif dans les bassins hydrographiques attenants menant à la contamination des sources d'eau. En raison de l'importance des fertilisants respectueux de l'environnement pour la protection de ce dernier, cette étude emploie une expérience avec choix discrets pour évaluer si les attributs écologiques des fertilisants influencent les préférences des consommateurs et leur volonté de payer pour une gestion durable de l'aménagement. Les résultats indiquent que les attributs écologiques des fertilisants influencent positivement les préférences des consommateurs et leur volonté de payer, appuyant ainsi la prémisse selon laquelle la promotion des attributs écologiques des fertilisants de gazon pourrait améliorer les écosystèmes locaux. De plus, cette étude évalue l'influence des attributs de certains fertilisants sur les préférences des propriétaires résidentiels dans les états avec et sans restrictions sur l'application des fertilisants. Puisque le cadre règlementaire peut avoir un impact sur les préférences des consommateurs pour une gestion durable de l'aménagement paysager, cette étude compare les prévisions des états avec et sans cadre règlementaire. Les résultats démontrent que les consommateurs sont plus aptes à utiliser, et sont disposés à payer un surplus pour les fertilisants durables dans les états où des règlements concernant l'utilisation de fertilisants résidentiels sont en vigueur, portant donc à croire que les programmes éducatifs concernant l'aménagement paysager respectueux de l'environnement devraient être accompagnés d'ordonnances strictes en matière de fertilisants.  相似文献

Soil water and nutrients are critical drivers of crop production for smallholders of southern Africa. A three-year study was conducted to assess the effect of integrating single and double ploughing, ripping and planting basins with nitrogen fertilizer (0, 10 and 20?kg?N?ha–1) on soil water dynamics and maize (Zea mays L.) yields. The experimental design was factorial with four tillage methods and three nitrogen levels as treatment factors. The study was conducted under semi-arid conditions of Zimbabwe. Tillage methods had similar soil water patterns in the profile and no tillage?×?N interaction effects were observed on soil water dynamics. Soil water penetrated deeper into the profile under ripper and basin methods than conventionally ploughed treatments. Nitrogen increased maize yields (14–96%) and rainwater-use efficiency (20–92%) regardless of tillage methods and growing season quality. However, more studies are required to explore complementary techniques that can improve rainwater capture and prolong soil water storage, and improve soil fertility.  相似文献

We use a pseudo‐panel data approach to analyze the relationship between the consumptions of cigarettes, alcohol, and coffee in a rational addiction framework. We find that while cigarette and coffee demands fit well with the rational addiction model, alcohol demand conforms to a model with inventory effects. The results suggest that alcohol consumption increases the marginal utility derived from consumption of cigarettes. Increasing alcohol prices would decrease not only the consumption of alcohol, but also the consumption of cigarettes. On the other hand, increasing cigarette prices do not have the same effect on consumption of alcohol. The cross‐price elasticity of coffee with respect to cigarette price is positive and significant which suggests that coffee substitutes for cigarettes when cigarette prices increase. The cross‐price elasticity of alcohol with respect to coffee price is found to be negative and significant. On the other hand, Morishima elasticities of substitution indicate that cigarette, alcohol and coffee substitute each other along the indifference curve when relative prices change.  相似文献

Financial institutions are struggling with larger volume, more specific and greater frequency of regulatory reporting after the global financial crisis in 2008, especially those that need to report to multiple jurisdictions. To help to improve reporting efficiency, this paper aims to assess the existence of similarities between templates related to credit and counter party credit risk of COREP and Pillar 3 regulatory reporting frameworks by applying Correspondence Analysis and Association Rules Mining. Our results suggest a high degree of overlap between these reporting frameworks, more prominently the three business functions as Front office, Finance and Risk. These patterns can be used as guidance for financial institutions to reshape their reporting architecture.  相似文献

The article describes the development, purification, and validation of a reliable self-report scale designed to measure the Desire for Visual Aesthetics (DVA) in the store environment. There is limited literature on the subject and a measurement scale has eluded both academicians and practitioners that could help measure the need for aesthetics in the retailing environment and help marketers decide on the level and type of aesthetics for the different segments in the target market/s and also the different type of retail stores. We used 3 focus groups, 8 individual interviews, and 891 surveys to develop, purify, and validate the 9-item Likert type scale. We also provide evidence for dimensionality, reliability, and validity. The scale could be used by academicians and practitioners alike, and could replace single items to measure the concept.  相似文献

This paper uses a natural experiment—the Super Bowl—to study the causal effect of advertising on demand for movies. Identification of the causal effect rests on two points: 1) Super Bowl ads are purchased before advertisers know which teams will play; 2) home cities of the teams that are playing will have proportionally more viewers than viewers in other cities. We find that the movies in our sample experience on average incremental opening weekend ticket sales of about $8.4 million from a $3 million Super Bowl advertisement.  相似文献

Global leaders agree on the need to substantially decarbonize the global economy by 2050. This paper compares potential costs associated with different policy pathways to achieve tourism sector emission reduction ambitions (?50% by 2035) and transform the sector to be part of the mid-century decarbonized economy (?70% by 2050). Investment in emissions abatement within the tourism sector, combined with strategic external carbon offsets, was found to be approximately 5% more cost effective over the period 2015–2050 than exclusive reliance on offsetting. The cost to achieve the ?50% target through abatement and strategic offsetting, while significant, represents less than 0.1% of the estimated global tourism economy in 2020 and 3.6% in 2050. Distributed equally among all tourists (international and domestic), the cost of a low-carbon tourism sector is estimated at US$11 per trip, equivalent to many current travel fees or taxes. Exclusive reliance on offsetting would expose the sector to extensive and continued carbon liability costs beyond mid-century and could be perceived as climate inaction, increasing reputational risks and the potential for less efficient regulatory interventions that could hinder sustainable tourism development. Effective tourism sector leadership is needed to develop a strategic tourism policy framework and emission measurement and reporting system.  相似文献
