We consider the extent to which U.S. fast-food businesses could adjust to an increase in the federal minimum wage from its current level of $7.25 an hour to $15 an hour without having to resort to reducing their workforce. We consider this issue through a set of simple illustrative exercises, whereby the US raises the federal minimum wage in two steps over four years, first to $10.50 within one year, then to $15 after three more years. We conclude that the fast-food industry could absorb the increase in its overall wage bill without resorting to cuts in their employment levels at any point over this four-year adjustment period. We find that the fast-food industry could fully absorb these wage bill increases through a combination of turnover reductions, trend increases in sales growth, and modest annual price increases over the four-year period. Working from the relevant existing literature, our results are based on a set of reasonable assumptions on fast-food turnover rates, the price elasticity of demand within the fast-food industry, and the industry’s underlying trend for sales growth. We also show that fast-food firms would not need to lower their average profit rate during this adjustment period. 相似文献

AbstractBackground: The prevalence of nontuberculous mycobacterial lung disease (NTMLD) in the US has increased; however, data characterizing the associated healthcare utilization and expenditure at the national level are limited.Objective: To examine associations between economic outcomes and the use of anti-Mycobacterium avium complex (MAC) guidelines-based treatment (GBT) for newly-diagnosed NTMLD in a US national managed care claims database (Optum® Clinformatics® Data Mart).Methods: NTMLD was defined as having ≥2 claims for NTMLD (ICD-9 031.0; ICD-10 A31.0) on separate occasions ≥30?days apart (between 2007 and 2016). The cohort included patients insured continuously over a period of at least 36?months (12?months before initial NTMLD diagnostic claim and for the subsequent 24?months). Treatment was classified as GBT (consistent with American Thoracic Society/Infectious Diseases Society of America guidelines), non-GBT, or untreated. All-cause hospitalization rates and total healthcare expenditures at Year 2 were assessed as outcomes of the treatment prescribed in Year 1 after NTMLD diagnosis.Results: A total of 1,039 patients met study criteria for NTMLD (GBT, n?=?294; non-GBT, n?=?298; untreated, n?=?447). After adjustment for baseline characteristics, GBT was associated with a significantly lower all-cause hospitalization risk vs non-GBT (odds ratio [OR]?=?0.53; 95% CI = 0.33–0.85, p?=?0.008), and vs being untreated (OR = 0.57; 95% CI = 0.35–0.91, p?=?0.020). Adjusted total healthcare expenditure in Year 2 with GBT ($69,691) was lower than that with non-GBT ($77,624) with a difference of ?$7,933 (95% CI = ?$14,968 to ?$899; p?=?0.03).Conclusions: Patients with NTMLD in a US managed care claims database who were prescribed GBT had lower hospitalization risk than those who were prescribed non-GBT or were untreated. GBT was associated with lower total healthcare expenditure compared with non-GBT. 相似文献

自然资源有无价值直接影响到经济发展方式和对自然资源开发利用的态度。从哲学角度出发,结合劳动价值论和效用价值论的相关理论,可以认为,自然资源的价值在于其满足人们的需要,自然资源价值量的大小取决于其稀缺性、开发条件和重置成本。如何对自然资源合理利用,关键是对其价值计算和比较。 相似文献

试论对食品安全监管者的再监管 总被引:3,自引:0,他引:3
喻玲 《江西财经大学学报》2009,(2):91-95
食品具有入口特征,生命具有不可回复性,所以对食品安全的监管与其他市场监管的最大不同就在于,食品安全监管要重在预防.食品安全监管存在一系列失灵,这也是食品安全事件频发的原因.食品安全监管权配置的不科学"多头性",导致了监管过度、监管不足及监管不当现象同时存在.改进监管效果的最优手段不是设立新的监管部门,而是利用和整合现有监管资源.包括:信息披露、明确监管主体及其职责、加强再监管激励、完善对监管主体的财务及认识监管以及建立有效的问责机制. 相似文献

Although the importance of the role of local food in tourism has begun to form an academic debate in the last decade, little effort has been invested in understanding what tourist motivations influence consumption of local food and beverages in a tourist destination and to develop a measurement scale for those motivations. Thus, this study adopted the comprehensive procedures of measurement scale development recommended by prior studies. The scale development procedure yielded a five factor measurement scale with acceptable levels of reliability and validity. Five underlying motivational dimensions of local food consumption were labelled: cultural experience; interpersonal relation; excitement; sensory appeal; and health concern. The outcomes and applications of the developed scale are discussed both in terms of theoretical and managerial implications. 相似文献

Self-classification is used as an a priori approach to tourist typology and market segmentation. However, skepticism still surrounds its ability to incorporate the multidimensionality of tourist behavior. This study seeks to empirically verify the efficacy of a single-item self-classification approach. The robustness of this self-classification measure is examined by comparing it to a data-driven multidimensional psychographic approach in terms of its ability to predict the behaviors of tourists toward food-related destination consumption. Results suggest that the single-item self-classification approach performs equally well as the psychographic approach in segmenting food-related consumption behaviors. The implications and limitations of this study are also discussed. 相似文献

AbstractAttitudes are at the heart of the Theory of Reasoned Action (TRA), but problems in defining and measuring attitudes have contributed to typically low ability to predict behaviour. This article investigates the impact of potential disjuncture between evaluations that an individual externally verbalises (explicit attitudes), and evaluations that are internally held and may exist outside of conscious awareness (implicit attitudes), on the predictive ability of TRA. We study consumers’ attitudes towards eating healthy food and subsequent behaviour in a context of socially consensual behaviour. An Implicit Association Test (IAT) is used to measure implicit attitudes, and these scores are contrasted with self-reported explicit attitude scores. Ninety one participants took part in the study. We found, surprisingly, that implicit attitude has no significant effect on behavioural intention. However, a disjuncture between an individual’s implicit and explicit attitudes, reflecting internal psychological conflict, affected behaviour. 相似文献
