This article examines the nature of employee relations in three of the leading food retailers in the UK. It compares and contrasts policies and practices by analysing the links between product markets, management choice, and employee relations. Special reference is made to features of work relations, employment relations, and industrial relations 相似文献
Consistency and flexibility are desirable, but incompatible, features of decision-making procedures. A comparison of a rule-based decision procedure (maximizing consistency) with a discretionary decision procedure (maximizing flexibility) was conducted. Employee voice was predicted to interact with decision procedure in impacting fairness perceptions. Student participants (N = 128) in a 2 × 2 laboratory simulation viewed videotaped depictions of a supervisor discussing a positive drug test result with an employee. The employee was given, or not given, an opportunity to explain; the supervisor was permitted discretion in determining the consequence or was completely bound by company policy. The proposed advantages of each decision procedure were obtained under contrasting levels of employee voice. Voice was desirable when the supervisor had discretionary authority; voice was unnecessary or even detrimental when a rule-based procedure was used. No overall preference between these two decision procedures was evident.相似文献
To estimate biologic cost per effectively treated patient with rheumatoid arthritis (RA) using a claims-based algorithm for effectiveness.
Methods:
Patients with RA aged 18–63 years in the IMS PharMetrics Plus database were categorized as effectively treated if they met all six criteria: (1) a medication possession ratio ≥80% (subcutaneous) or at least as many infusions as specified in US labeling (intravenous); (2) no biologic dose increase; (3) no biologic switch; (4) no new non-biologic disease-modifying anti-rheumatic drug; (5) no new or increased oral glucocorticoid; and (6) ≤1 glucocorticoid injection. Biologic cost per effectively treated patient was defined as total cost of the index biologic (drug plus intravenous administration) divided by the number of patients categorized by the algorithm as effectively treated. Similar methods were used for the index biologic in the second year and for a second biologic after a switch.
Results:
Rates that the index biologic was categorized as effective in the first year were 31.0% etanercept (2243/7247), 28.6% adalimumab (1426/4991), 28.6% abatacept (332/1160), 27.2% golimumab (71/261), and 20.2% infliximab (474/2352). Mean biologic cost per effectively treated patient, per the algorithm, was $50,141 etanercept, $53,386 golimumab, $56,942 adalimumab, $73,516 abatacept, and $114,089 infliximab. Biologic cost per effectively treated patient, using this algorithm, was lower for patients who continued the index biologic in the second year and higher after switching.
Conclusions:
When a claims-based algorithm was applied to a large commercial claims database, etanercept was categorized as the most effective and had the lowest estimated 1-year biologic cost per effectively treated patient. This proxy for effectiveness from claims databases was validated against a clinical effectiveness scale, but analyses of the second year or the year after a biologic switch were not included in the validation. Costs of other medications were not included in cost calculations. 相似文献
The teaching of management accounting at tertiary institutions drew criticism in the mid-to-late 1980s on the grounds that course content and teaching methods were not keeping pace with changes in manufacturing technologies and the business environment. A study of management accounting programs in 30 Australian universities shows that the criticisms are largely being addressed, with most programs being well up-to-date in their coverage of many of the new topics and practices that have emerged in management accounting in recent years. Nonetheless, management accounting educators continue to see a number of constraints on effective teaching in this area. 相似文献
We study global games with strategic substitutes. Specifically, for a class of binary‐action, ‐player games with strategic substitutes, we prove that under payoff asymmetry, as incomplete information vanishes, the global games approach selects a unique equilibrium. We characterize this equilibrium profile ; players employ switching strategies at different cutoff signals, the order of which is directly determined by payoff asymmetry. We provide examples that illustrate our result and its connection with dominance solvability. We extend the global game literature, which has thus far been developed for games with strategic complementarities, to new applications in industrial organization, collective action problems, finance, etc . 相似文献
We compare several emissions reduction instruments, including quantity policies with banking and borrowing, price policies, and hybrid policies (safety valve and price collar), using a dynamic model with stochastic baseline emissions. The instruments are compared under the design goal of obtaining the same expected cumulative emissions across all options. Based on simulation analysis with the model parameterized to values relevant to proposed US climate mitigation policies, we find that restrictions on banking and borrowing, including the provision of interest rates on the borrowings, can severely limit the value of the policy, depending on the regulator-chosen allowance issuance path. Although emissions taxes generally provide the lowest expected abatement costs, a cap-and-trade system combined with either a safety valve or a price collar can be designed to provide expected abatement costs near those of a tax, but with lower emissions variance than a tax. Consistently, a price collar is more cost-effective than a safety valve for a given expected cumulative emissions outcome because it encourages inexpensive abatement when abatement costs decline. 相似文献
We model a market populated by two groups of boundedly rational agents: "newswatchers" and "momentum traders." Each newswatcher observes some private information, but fails to extract other newswatchers' information from prices. If information diffuses gradually across the population, prices underreact in the short run. The underreaction means that the momentum traders can profit by trend-chasing. However, if they can only implement simple (i.e., univariate) strategies, their attempts at arbitrage must inevitably lead to overreaction at long horizons. In addition to providing a unified account of under- and overreactions, the model generates several other distinctive implications. 相似文献
