Testing servers' roles as experts and managers of tipping behaviour

This article studies the ability of servers to predict their own tips. A distinction is made between the two roles of servers with regard to tipping behaviour: the role of expert and the role of manager. As experts, servers understand the relations between several predictors and tip size, and are able to predict the tip they are about to receive. As managers, servers designate certain tip amounts, and then manage the service encounter so that their predictions are realised. This study maps the necessary conditions for an expert position and outlines the process for managing a service encounter. Empirical testing suggests that servers have an impressive predictive ability. The findings also offer some support to the view of the role of the server as manager.     

Temporal and Regional Differences In Image of a Tourist Destination: Implications for Promoters of Tourism

Based on a survey of 218 respondents from four different regional groupings, the study focuses on examining the temporal and spatial differences of the image tourists had of a place of visit. The results show that there are significant differences among some items of the image scale both in the temporal and spatial aspects. The implications and relevance of such Q study

are also discussed.     

It’s all about audit quality: Perspectives on strategic-systems auditing

We discuss the antecedents of and rationale for what has become known as Strategic-Systems Auditing (SSA). We also describe the conceptual foundation and key elements of SSA. We observe that the auditor employing SSA conceives the audit as a process of evidence-driven, belief-based, risk assessment. We also illustrate facets of this process, including how the auditor, by acquiring a rich understanding of how and how well management is executing its business-model, develops rich (e.g., distributional) expectations of future financial-statement amounts and disclosures. These expectations form a benchmark against which the auditor later compares and investigates management’s asserted financial-statement amounts and disclosures. Finally, we pose and respond to some of the more common questions about elements of SSA and complete the paper by suggesting some educational innovations and high-value targets for research.One salient message is that SSA first emerged in the 1990s as an attempt to enhance audit quality in response to changes in the audit environment. Another salient message is that SSA continues to equilibrate, adapting to more recent environmental changes, especially society’s demand for greater protection from financial-statement fraud. Such adaptation requires ongoing, significant intellectual investments by audit practitioners and audit scholars/educators.     

Bonuses and Non-Public Information in Publicly Traded Firms

Recent research in accounting explores how firms use “individual” or “non-financial” measures of performance in executive compensation contracts. We model a firm that conditions bonus payments to executives on information that is not available to those outside the firm. This raises two issues. First, market participants may use the magnitude of such payments to infer the non-public information. Second, because information that is non-public is, by extension, non-verifiable, the firm cannot write explicit contracts based on it. Combining the relational incentive contracts and financial signaling literatures, we examine equilibria of a signaling game in which bonus payments from a firm to a manager convey non-public information regarding the firm’s future cash flows. Our main result is that increases in corporate myopia can, under some conditions, lead to increased profits. This finding is contrary to that typically found in financial signaling models.     

Cost-effectiveness of metformin plus vildagliptin compared with metformin plus sulphonylurea for the treatment of patients with type 2 diabetes mellitus: a Portuguese healthcare system perspective

Objective:

To evaluate the cost-effectiveness of vildagliptin plus metformin vs generic sulphonylurea plus metformin in patients with type 2 diabetes mellitus, not controlled with metformin, from a Portuguese healthcare system perspective.

Methods:

A cost-effectiveness model was constructed using risk equations from the UK Prospective Diabetes Study Outcomes Model with a 10,000-patient cohort and a lifetime horizon. The model predicted microvascular and macrovascular complications and mortality in yearly cycles. Patients entered the model as metformin monotherapy failures and switched to alternative treatments (metformin plus basal-bolus insulin and subsequently metformin plus intensive insulin) when glycated hemoglobin A1c >7.5% was reached. Baseline patient characteristics and clinical variables were derived from a Portuguese epidemiological study. Cost estimates were based on direct medical costs only. One-way and probabilistic sensitivity analyses were conducted to test the robustness of the model.

Results:

There were fewer non-fatal diabetes-related adverse events (AEs) in patients treated with metformin plus vildagliptin compared with patients treated with metformin plus sulphonylurea (6752 vs 6815). Addition of vildagliptin compared with sulphonylurea led to increased drug acquisition costs but reduced costs of AEs, managing morbidities, and monitoring patients. Treatment with metformin plus vildagliptin yielded a mean per-patient gain of 0.1279 quality-adjusted life years (QALYs) and a mean per-patient increase in total cost of €1161, giving an incremental cost-effectiveness ratio (ICER) of €9072 per QALY. Univariate analyses showed that ICER values were robust and ranged from €4195 to €16,052 per QALY when different parameters were varied.

Limitations:

The model excluded several diabetes-related morbidities, such as peripheral neuropathy and ulceration, and did not model second events. Patients were presumed to enter the model with no diabetes-related complications.

Conclusion:

Treatment with metformin plus vildagliptin compared with metformin plus sulphonylurea is expected to result in a lower incidence of diabetes-related AEs and to be a cost-effective treatment strategy.     

Funding Pain: Bedouin Women and Political Economy in the Naqab/Negev

ABSTRACT

This contribution focuses on the experiences and voices of Palestinian Bedouin women surviving and challenging Israeli colonial policies while residing in their own land and, in particular, the Bedouin women of the Naqab living in unrecognized villages. Through interviews and focus groups, this study learns from and engages with the voices of Palestinian Bedouin women because colonized women's criticisms of the political economic apparatus are seldom invoked to influence policy. Exploring these women's voices offers an opportunity to examine the political economy of their unrecognized, officially nonexistent villages and homes and to rectify the gap in bottom-up knowledge of political economy by investigating the institutional structures that define and circumscribe women's lives. Privileging Bedouin women's production of knowledge carries the analytical value of studying political economy based on women's own experiences and struggles against hegemony.     

Do changes in credit ratings of REITs affect their capital structure decisions?

Existing research has highlighted the high leverage ratio of Real Estate Investment Trusts (REITs). To the extent that credit rating is important to REITs when sourcing for capital from the public debt markets, our paper investigates the effect of changes in REIT credit ratings on capital structure decisions while controlling for endogeneity effects. Our results indicate that REITs that face the prospect of an imminent credit rating downgrade issue approximately 11% less debt net of equity as a percentage of total assets than other REITs. This effect is asymmetric in that positive rating outlooks do not have a significant impact on REIT capital structure activities.     

Co-ethnic markets: Financial penalty or opportunity?

This paper applies the view of resource based theory to minority entrepreneurship. It examines minority entrepreneurs’ reliance on co-ethnic markets in terms of the impact this has on the financial performance of their firms. This research focuses on three minority groups in particular: African Americans, Korean Americans and Mexican Americans. Findings indicate that owner's age and marital status, but not business age, shape the extent to which a business owner relies on co-ethnic clients. Furthermore, Korean American owned firms are less likely to have high proportions of co-ethnic clients compared to Mexican- and African American owned firms. Having a large co-ethnic clientele results in a financial penalty in terms of the revenue an owner draws from his or her business. This penalty occurs in businesses owned by all three groups of entrepreneurs. Findings lend support to the resource based theory view of the firm in terms of the need to dynamically apply resources in order to achieve a competitive advantage. Implications for theory and practice are discussed.
