The relationship between routine work stress and psychological distress was investigated among 733 police officers in three US cities, during 1998‐1999. The Work Environment Inventory (WEI) was developed to assess exposure to routine work stressors, while excluding duty‐related traumatic stressors (critical incidents). The WEI and its general properties are presented. The relationship between routine work stress exposure and psychological distress is then explored. Exposure to routine work stressors predicted general psychological distress (r = 0.46), as well as post‐traumatic stress symptoms following officers’ most traumatic career incident (rs = 0.26 to 0.39). Multivariate analyses found that these effects were independent of, and larger than, the effects of cumulative critical incident exposure. (Time since the most traumatic event, social support, and social desirability effects were also controlled statistically.) Routine occupational stress exposure appears to be a significant risk factor for psychological distress among police officers, and a surprisingly strong predictor of post‐traumatic stress symptoms.

People can easily track and understand their usage pattern for any content (e.g. movies, games) or service (e.g. card payment, cell phone usage) by using technologies such as the internet and smart phones. When consumers evaluate their past consumption patterns, they may experience two different kinds of regret: content-based or monetary-based. The purpose of this paper is to propose that perceived self-control, defined as the extent to which people believe they can control their usage, plays a moderating role in the tariff-choice process (flatrate vs pay-per-use) for two types of content: vice-based and virtue-based.

Two laboratory experiments were designed to test the hypotheses. There were a total of 200 participants (86 for Experiment 1 and 114 for Experiment 2) who completed the entire experimental process (i.e. stimulus exposure, questionnaire reporting, dependent variable measurement, manipulation of the independent variables, and control checks).

The results of this research provide evidence supporting the role of perceived self-control in tariff preference by showing that preference varies between flat-rate and pay-per-use tariff options. Specifically, virtue-based content users were more likely to prefer the pay-per-use tariff when their perceived self-control was low vs when it was high. In contrast, vice-based content users were more likely to prefer the flat-rate tariff when their perceived self-control was low vs when it was high.

There are three contributions of the present research. First, the authors investigated the effect of content type on tariff preference. Second, the authors suggest that there is a moderating effect of perceived self-control on tariff preference. Third, this study revealed the factors affecting consumers’ perceived self-control.

The purpose of this paper is to take a close look at competition among the generic entrants during the first three years after patent expiration and examine whether there is a first mover advantage. Pharmaceutical markets experience the entry of numerous generic firms upon expiration of the brand firm’s patent.

A random effect nested logit model of competition that allows for competition between the brand drug and generics, and among multiple generic drugs is specified. The model accommodates the effects of prices, detailing, sampling, journal advertising, time-in-market and molecule-specific characteristics. The model is estimated on cross-section time-series data for 49 molecules in which the brand drug lost patent exclusivity between 1992 and 2000.

Strong evidence that the early generic entrant enjoys a substantial market share and profit advantage over the second and the third entrants, after controlling for differences in marketing activities was found. In addition, evidence suggesting that the advantage is due to the response of the retail pharmacy channel and due to differential effectiveness of advertising and pricing between earlier versus later entrants was found.

This paper is the first to empirically model first mover advantage among undifferentiated products. The findings are useful for regulators in pharmaceutical and healthcare industries. They can also shed light on other industries where there is little or no quality differentiation, such as commodity trading, open-source software distribution and online banking.

Short delivery time is a feature that can influence consumers’ purchasing decisions and that retailers compete over fiercely. Accordingly, evaluating the effect of delivery time on demand and identifying marketing-mix variables that alter this relationship may influence retailers’ strategies and impact supply chain (SC) performance. The paper aims to discuss these issues.

This study was performed in collaboration with the largest furniture retailer in Italy, which provided its sales and inventory data for 19,000 units sold over a six-month period in 32 stores throughout Italy. Data were analysed using logistic regression with fixed effects.

The value of delivery time for consumers, even in an industry generally characterised by long delivery lead times, is surprisingly high. The evidence reveals that when the delivery time changes from two days to seven days, demand is reduced by 37.5 per cent, although variables related to location and the marketing mix moderate this relationship.

Retailers can use the findings presented herein to drive their inventory and facility planning decisions and support investments in SC integration.

Supply chain management (SCM) studies consider the value of delivery time anecdotally and have neglected empirical estimations of the magnitude of the effects of delivery time on consumer demand. Further, SCM studies have not explored the factors moderating this relationship, although intertemporal choice and service management studies have demonstrated the existence of such factors.
