LIQUIDITY AND TICK SIZE: DOES DECIMALIZATION MATTER?

The effect of the move to decimalization by the Toronto Stock Exchange, where the minimum tick size was decreased to $0.05 from $0.125, is examined. Liquidity is measured by the price impact of unexpected volume. Results show an unambiguous gain to investors. Effective spreads decrease significantly, but the price impact is unaffected. In addition, evidence indicates an increase in trading activity in absolute terms as well in relation to U.S. exchanges for cross-listed stocks. This is consistent with the observed decrease in transaction costs.     

Shared knowledge and product design glitches in integrated product development

Product development processes based on the joint collaboration of the cross-functional team, suppliers, and customers can minimize project glitches. Glitches in the product development project can cause project cost over-runs and delay a project past when first mover advantages are possible. While previous theoretical work has suggested a negative relationship between shared knowledge and product development glitches, empirical studies have not identified how different types of shared knowledge are associated with each other and the design glitches. This study proposes a model of the relationship between specific types of shared knowledge and design glitches in integrated product development (IPD) projects. We test our model using a sample of 191 projects from the automotive industry in the United States. The major findings were that: (1) shared knowledge of the development process can be built by improving a team's shared knowledge of customers, suppliers, and internal capabilities, (2) shared knowledge of the development process for a project reduces product design glitches, and (3) reduced product design glitches improve product development time, cost, and customer satisfaction.     

Accounting and Medicine: An Exploratory Investigation into Physicians’ Attitudes Toward the Use of Standard Cost-Accounting Methods in Medicine

Research studies demonstrate wide variation in how physicians diagnose and treat patients with similar medical conditions and suggest that at least some of the variation reflects inefficiencies and unnecessary medical costs. Health care researchers are actively examining ways to reduce variations in practice through standardization of medicine to reduce the cost of treatment and ensure the quality of outcomes. The most widely accepted form of this standardization is Evidence Based Best Practices (EBBP). Furthermore, financial health care providers such as hospitals and managed care organizations are investigating methods to tie resource usage to medical protocols in their efforts to monitor and control health care costs. Such proposals are contentious because they report on physicians’ medical practice behaviors (such as the number of tests ordered, use of specific therapies, etc.) and such reports could potentially be used to influence their clinical behaviors. The intent of this exploratory study was to examine physicians’ perceptions about linking a standard costing system to EBBP guidelines. The authors interviewed nine practicing physicians asking each physician to respond to the question, ‘As a physician working in a hospital environment, what are your reactions to and concerns with combining standard costing techniques with EBBP?’ The interviews were in-depth and free form in nature. The physicians’ responses were recorded and analyzed using Grounded Theory Methodology. Using this methodology the field data was categorized into two major themes. The most important theme centered on ethics and the second theme was concerned with the implementation and use of a standard cost system in regard to EBBP. If physicians’ worries about ethical dilemmas and implementation issues are not resolved, then it is likely that doctors would be unwilling to participate in any efforts to develop or use a standard cost-reporting system in medicine. While this study was exploratory in nature, it should provide future guidance to accountants, health care researchers and health care providers about physicians’ issues with the use of standard costing methods in medicine.     

Professional Ethics in a Virtual World: The Impact of the Internet on Traditional Notions of Professionalism

Numerous articles in the popular press together with an examination of websites associated with the medical, legal, engineering, financial, and other professions leave no doubt that the role of professions has been impacted by the Internet. While offering the promise of the democratization of expertise – expertise made available to the public at convenient times and locations and at an affordable cost – the Internet is also driving a reexamination of the concept of professional identity and related claims of expertise and standards of integrity.This paper begins with a presentation of case studies illustrating the ease by which impostors infiltrate the ranks of professionals. Reports of individuals masquerading as professionals via the Internet often reveal that these imposters cause harm to the unwary victims who rely on assertions of professional expertise. Such reports motivated the authors to examine the origins and evolution of the traditional roles of professions and professionals in today’s society, as well as question how, or whether, the standards for professional practice have been adapted to the challenges posed by technology, i.e., do statements of professional ethics provide a ‘guiding light’ for practitioners and their clients in the cyber age? The authors challenge the professions to consider the notion that technology forces a confrontation between the guild-like aspects of a profession that have served, on the one hand, to protect a profession from encroachment and, on the other hand, have purportedly protected the public.The authors conclude by presenting an examination of websites that show recognition of the challenges that the Internet poses to professionalism, as we have known it. Detailed discussion of the websites of two professions illustrates different approaches to responding to these challenges.     

The effects of relationship quality on customer retaliation

This research examines the effects of relationship quality (RQ) on customers' desires to retaliate after service failures. We posit that the effects of RQ are contingent upon the attributions customers make about the firm’s controllability over a service failure. Two competing hypotheses are examined and reconciled. The “love is blind” hypothesis posits that when low controllability is inferred, high RQ customers experience a lesser desire for retaliation than low RQ customers. On the other hand, the “love becomes hate” hypothesis specifies that when high controllability is inferred, high RQ customers experience a greater desire for retaliation than low RQ customers. The hypotheses are tested with a survey-based design and a partial least squares (PLS) model that incorporates a multiplicative latent construct.
