Merit pay,performance appraisal,and individual motivation: An analysis and alternative

Theories of motivation and common expectation argue that people who contribute more to an undertaking should receive more from it. This expectation has significantly influenced the design of compensation systems. Merit pay reflects this influence. Nonetheless, in spite of intuitive appeal and apparent theoretical support, merit pay rarely achieves its objectives. This article reviews five common implementation issues. It also argues that merit plans underemphasize important attribution biases that affect performance judgments. These biases suggest that such plans would still have limited effectiveness, even if implementation problems were overcome. The article presents an alternative focused on group accomplishment. © 1998 John Wiley & Sons, Inc.     

Understanding the economic,daily functioning,and diabetes management burden of non-severe nocturnal hypoglycemic events in Canada: differences between type 1 and type 2

Objective:

To examine the daily functioning, diabetes management, and economic burden of non-severe nocturnal hypoglycemic events (NSNHEs) in Canada and differences in impacts by diabetes type.

Research design and methods:

A 20-min web-based survey, with items derived from the literature, expert and patient interviews, assessing the impact of NSNHEs, was administered to patients with self-reported diabetes aged ≥18 having an NSNHE in the past month.

Results:

Two thousand, two hundred and seventy-nine Canadian persons with diabetes were screened with 200 respondents meeting criteria and included in the analysis sample. Out of 87 working respondents, 15 reported on average 3.5?h of lost work (absenteeism). The reduction in work productivity (presenteeism) reported was comparable to the impact of arthritis. Other functional impacts included sleep and daily activities. Additionally, respondents’ increased their usual blood sugar monitoring practice, on average, 4.2 (SD?=?7.5) extra tests were conducted in the week following the event and reduced their insulin over the following 4.8 days. Increased healthcare utilization was also reported. Increased costs as a result of NSNHE for lost work productivity, increased diabetes management, and resource utilization was CAD 70.67 per person per year in this sample. Limitations of the study include the biases which are associated with a web-based survey and self-reported data.

Conclusions:

NSNHEs have serious consequences for patients and diabetes management practices. Greater attention to treatments which reduce NSNHEs can have a major impact on improving functioning while reducing the economic burden of diabetes.     

Choosing a digital content strategy: How much should be free?

Advertising supported content sampling is ubiquitous in online markets for digital information goods. Yet, little is known about the profit impact of sampling when it serves the dual purpose of disclosing content quality and generating advertising revenue. This paper proposes an analytical framework to study the optimal content strategy for online publishers and shows how it is determined by characteristics of both the content market and the advertising market. The strategy choice is among a paid content strategy, a sampling strategy, and a free content strategy, which follow from the publisher's decisions concerning the size of the sample and the price of the paid content. We show that a key driver of the strategy choice is how sampling affects the prior expectations of consumers, who learn about content quality from the inspection of the free samples. Surprisingly, we find that it can be optimal for the publisher to generate advertising revenue by offering free samples even when sampling reduces both prior quality expectations and content demand. In addition, we show that it can be optimal for the publisher to refrain from revealing quality through free samples when advertising effectiveness is low and content quality is high. To illustrate, we relate our framework to the newspaper industry, where the sampling strategy is known as the “metered model.”     

Advanced practice nurse outcomes 1990-2008: a systematic review

Advanced practice registered nurses have assumed an increasing role as providers in the health care system, particularly for underserved populations. The aim of this systematic review was to answer the following question: Compared to other providers (physicians or teams without APRNs) are APRN patient outcomes of care similar? This systematic review of published literature between 1990 and 2008 on care provided by APRNs indicates patient outcomes of care provided by nurse practitioners and certified nurse midwives in collaboration with physicians are similar to and in some ways better than care provided by physicians alone for the populations and in the settings included. Use of clinical nurse specialists in acute care settings can reduce length of stay and cost of care for hospitalized patients. These results extend what is known about APRN outcomes from previous reviews by assessing all types of APRNs over a span of 18 years, using a systematic process with intentionally broad inclusion of outcomes, patient populations, and settings. The results indicate APRNs provide effective and high-quality patient care, have an important role in improving the quality of patient care in the United States, and could help to address concerns about whether care provided by APRNs can safely augment the physician supply to support reform efforts aimed at expanding access to care.     

An experimental test of behavior under team production

This study reports experiments that examine behavior under team production and a piece rate. In the experiments, participants complete a forecasting task and are rewarded based on the accuracy of their forecasts. In the piece‐rate condition, participants are paid based on their own performance, whereas the team‐production condition rewards participants based on the average performance of the team. Overall, there is no statistically significant difference in performance between the conditions. However, this result masks important differences in the behavior of men and women across the conditions. Men in the team‐production condition increase their performance relative to men in the piece‐rate condition. However, this gap in male performances across conditions diminishes over the course of the experiment. In contrast, women in the team‐production condition show significantly lower performance than the women in the piece rate. As a consequence of these differences, men in the team‐production condition show significantly better performance than women in the team‐production condition. We also find evidence that men show stronger performance when they are in teams with a larger variation in skill level. Copyright © 2010 John Wiley & Sons, Ltd.     

Scottish theme towns: have new identities enhanced development?

Three small towns in southwest Scotland have recently been branded as distinct theme towns, based on books, artists and food. This is an attempt to make them more attractive to visitors and thereby improve their economy. The objective of this research is to establish whether the new identities possessed by the towns have enhanced their development. It is argued, using data reviewing the past decade, that they have all developed, albeit at different rates, in terms of the economy and culture. Moreover, it is maintained that social capital has been enhanced and is a factor whose importance has been under-appreciated by planners and observers of this type of process. The relevance of the new identity to the pre-branding identity is also seen as a factor in successful development and ideas of authenticity and heritage are brought to bear on the relationship.     

Changes in Background Risk and the Demand for Insurance

The demand for insurance against loss from a particular risky asset is likely to depend on other risks the decision-maker faces. For independently distributed other risks, referred to as background risk, Eeckhoudt and Kimball [1992] determine the effect on insurance demand of introducing background risk. Recently, Eeckhoudt, Gollier, and Schlesinger [1996] determine conditions on preferences such that first- and second-degree stochastic deteriorations in background risk lead to a decrease in the decision-maker's willingness to accept other risks. These results, although formulated in a general decision model, also apply to insurance demand. This article continues analysis of this question by determining the effect on insurance demand of several other general changes in background risk.
