Abstract

Purpose

The purpose of this study is twofold: to investigate the correlation between the perception of respondent accountants (N = 164) on ethics elements and their demographic factors and to examine the gap between the expectations of employers (accountants) and the coverage of ethics in the education of professional accountants.

Design/methodology/approach

Both qualitative and quantitative methods were used to collect the data. An analysis of the relevant documents (syllabi and codes of ethics) was conducted to generate and group appropriate items that represent ethics themes. This led to 17 themes such as integrity, conflict of interest, ethics theories and resolving ethical dilemma. Using inputs from the qualitative study and relevant literature, a questionnaire was framed for the quantitative phase of this study.

Findings

Within accounting ethics education, more emphasis and awareness is required on the themes of integrity, independence, corruption and insider trading. Four categories emerge for the ethics themes related to education in accounting: “Integrity to Accounting Profession”, “Regulatory Compliance”, “Practical Ethical Issues” and “Sense of Responsibility”. The results of this study reveal there are gaps between ethics education and accountants’ expectations. It is found that accountants perceive more virtue-related elements be put in accounting education.

Practical implications

This study will make accounting educators, accountants and accounting professional associations to be more aware and work together to bridge this gap as well as contribute to a more effective ethics education for accountants in Hong Kong.

Originality/value

End of education is character and not merely the acquisition of intellectual prowess. With Aristotle’s wisdom and the learnings from the many corporate scandals, it would be safe to conclude that education should result in nurturing hearts and character and not just the transfer of worldly knowledge. While there are many studies focusing on perceptions about ethics, ethics education of business students or academics, there are hardly any studies available on accounting professionals’ perceptions on ethics education, especially in Hong Kong. The authors found that accountants want more virtue-related ethics elements included in accounting education.

Abstract

Purpose

This paper aims to analyze and give directions for advancing research in stock market volatility highlighting its features, structural breaks and emerging developments. This study offers a platform to research the benchmark studies to know the research gap and give directions for extending future research.

Design/methodology/approach

The author has performed the literature review, and, reference checking as per the snowballing approach. Firstly, the author has started with outlining and simplifying the significance of the subject area, the review illustrating the various elements along with the research gaps and emphasizing the finding.

Findings

This work summarizes the studies covering the volatility, its properties and structural breaks on various aspects such as techniques applied, subareas and the markets. From the review’s analysis, no study has clarified the supremacy of any model because of the different market conditions, nature of data and methodological aspects. The outcome of this research work has delivered further magnitude to research the benchmark studies for the upcoming work on stock market volatility. This paper has also proposed the hybrid volatility models combining artificial intelligence with econometric techniques to detect noise, sudden changes and chaotic information easily.

Research limitations/implications

The author has taken the research papers from the scholarly journal published in the English language only and the author may also consider other nonscholarly or other language journals.

Originality/value

To the best of the author’s knowledge, this research work highlights an updated and more comprehensive framework examining the properties and demonstrating the contemporary developments in the field of stock market volatility.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

This paper aims to study the post-patent ethical drug market and simulate the impact of Patient Protection and Affordable Care Act (ACA) on individuals, health-care providers and pharmaceutical firms. US policymakers have been looking at various ways to curb rising health-care costs in USA, including ways to promote the use of generic drugs in lieu of brand drugs. In this broader context, the implementation of ACA in December 2013 will introduce major changes in the pharmaceutical market.

Design/methodology/approach

To fully understand the impact of such policy changes, we develop a structural model to study consumers’ buying behavior and firm competition in the post-patent ethical drug markets. We use the estimated model parameters to conduct four policy simulations to illustrate the effect of Obamacare on increasing the relative size of price-insensitive segment, reducing price sensitivity in the price-sensitive segment, providing brand price discount to Medicare patients previously in the “donut hole” and the effect of change in people’s attitude toward generics.

Findings

Our model estimation reveals two classes of consumers with different price sensitivities. This heterogeneity explains the increase in the brand price after generic entry. We identify consumers’ switching costs between generic and brand drugs, as well as among different generics. From the policy simulation, we find that except the closure of Medicare donut hole, all other policy changes lead to increased usage of the focal molecule, and the efforts to increase insurance coverage and reduce the out of pocket payment for prescription drugs lead to increase in firm profit.

Originality/value

This paper is the first to illustrate the potential policy effect of Obamacare through a structural model on post-patent ethical drug market.
