Toward an Understanding of Donor Loyalty: Demographics,Personality, Persuasion,and Revenue

Donor loyalty is linked to revenue generation in nonprofit organizations. This study utilized a consumer-based marketing approach to donors and their contributions via examining loyalty to nonprofit organizations. Through a detailed literature review that identified five specific hypotheses, tested using a secondary analysis of a large survey, and the design and implementation of a second (online) survey, this article empirically assesses donor loyalty and provides findings that develop the literature, support practice, and identify areas of future research. The results demonstrate the linkages between donor loyalty and revenue, and provide a deeper understanding of the relationship of demographic factors, preference for consistency, materialism, and maximization to donor loyalty. Notably, the results clearly illustrate that habitual switchers donate substantially less than loyal donors. A series of areas for future research are identified and a number of recommendations are provided to practitioners vis-à-vis understanding their donors and enhancing their revenues through donations.     

Bridging Industrial Segmentation Theory and Practice

Purpose: Segmentation is seen today as a core concept within mainstream marketing. While industrial segmentation has received considerable attention within academic literature, there have been many reports on companies having problems using, applying, and implementing the principles of segmentation. Authors criticize the literature on segmentation for giving too little attention to implementation, providing marketers little help and guidance on how to make segmentation work in a practical environment. This article addresses some of these problems.

Methodology/Approach: The objective of this article is to design a process with methods and activities for segmentation by building on action research case study data from a large Danish industrial company.

Findings: Along with important considerations, this article presents the process of segmentation using a build-up approach based on qualitative market data. The process is practical and easily approachable for companies. The purpose behind segmentation is strategic—identify target segments and facilitate the planning of future product offers. It is argued that segmentation should be dedicated to the purpose and context of the company. This case illustrates how the company adapted segmentation theory to their particular needs.     

Cost of operating room time for endovascular transcatheter aortic valve replacement

Abstract

Background: Procedural efficiencies can contribute to cost reductions in transcatheter aortic valve replacement procedures (TAVR). The objective of this study is to determine operating room (OR) variable cost per minute in endovascular TAVR procedures, in a real-world hospital setting.

Methods: Using Premier data from January 2015–June 2016 for patients undergoing a primary endovascular TAVR (primary ICD-9 code of 35.05, ICD-10 code of 02RF37Z, 02RF38Z, 02RF3JZ, or 02RF3KZ) procedure, the OR cost per minute was calculated for each patient by dividing the total hospital OR variable cost by the OR time (minutes).

Results: Of the 4,573 patients in the cohort, the average age was 80 years, 77% were admitted electively, and the vast majority were discharged home with (30%) or without (45%) home care. Median OR time for endovascular TAVR procedures was 180?min. The trimmed mean OR cost per minute was $43.59 (SD = $28.68). When stratified by Elixhauser Risk score and Charlson comorbidity index, OR cost per minute increased with higher risk and comorbidity (p?<?0.0001 and p?<?0.041, respectively).

Conclusions: This contemporary estimate of the real-world variable OR cost per minute provides researchers with a critical parameter to refine economic models of TAVR and aid clinical program directors in resource planning according to a priori risk and comorbidity.     

Exploring the relationship between investor sentiment and price volatility

By performing Grey relation analysis, this study elucidates the relationship between investor sentiment and price volatility in the Taiwanese stock market. A sequential relationship is identified between investor sentiment and price volatility, and ranked according to order of importance. Analytical results show that short sales volumes may be an individual leading indicator useful in observing the effects of sentiment on price volatility, followed by open interest put/call ratios and trading volumes, and buy/sell orders. Institutional investors are related, to a lesser extent, to price volatility and sentiment. Qualified foreign institutional investors, or more rational investors, are the least influenced by price volatility, followed by securities investment trust companies and dealers. TAIEX options exert the strongest influence on sentiment during the study period, making them a valuable reference for gauging price volatility.     

Bayesian estimation of truncated data with applications to operational risk measurement

Data insufficiency and reporting threshold are two main issues in operational risk modelling. When these conditions are present, maximum likelihood estimation (MLE) may produce very poor parameter estimates. In this study, we first investigate four methods to estimate the parameters of truncated distributions for small samples—MLE, expectation-maximization algorithm, penalized likelihood estimators, and Bayesian methods. Without any proper prior information, Jeffreys’ prior for truncated distributions is used. Based on a simulation study for the log-normal distribution, we find that the Bayesian method gives much more credible and reliable estimates than the MLE method. Finally, an application to the operational loss severity estimation using real data is conducted using the truncated log-normal and log-gamma distributions. With the Bayesian method, the loss distribution parameters and value-at-risk measure for every cell with loss data can be estimated separately for internal and external data. Moreover, confidence intervals for the Bayesian estimates are obtained via a bootstrap method.     

Auditor economic incentives and going-concern opinions in a limited litigious Continental European business environment: empirical evidence from Belgium

Theory predicts that auditor reporting behaviour may be influenced by the perceived consequences of disclosing going-concern uncertainty in the audit report (DeAngelo 1981, Watts and Zimmerman 1986). Krishnan and Krishnan (1996) and Louwers (1998) have addressed this issue empirically in a US context. The results of Krishnan and Krishnan (1996) suggested that one of the important factors in the auditor's opinion decision is the risk of litigation. The purpose of this study is to examine the relationship between auditor economic incentives and the propensity to issue going-concern opinions in a limited litigious business environment, Belgium. In spite of the low risk of litigation and the fact that most Belgian companies are privately held, various regulations have been put into effect to safeguard audit quality in Belgium. However, the results suggest that the auditor's going-concern opinion decision in Belgium is associated with factors relating to the perceived consequences of disclosing a going-concern opinion. Specifically, the results suggest that auditors in Belgium are significantly less likely to issue going-concern opinions to clients that pay higher audit fees, and when the audit firm has lost a relatively high proportion of its clients in the preceding year. The auditor's going-concern opinion does not appear to be significantly influenced by the length of the auditor-client relationship, year of the auditor engagement period, and auditor type. The results of this study are to some extent different from the study by Louwers (1998), in which none of the incentive variables related to the auditor's loss function was significant.     

Corporate Pyramids,Conservatism and Cost of Debt: Evidence From Taiwan

This study investigates the extent to which the span of corporate pyramids (as measured by the number of ownership layers) is associated with higher agency costs of debt, and whether conservatism can moderate the agency cost. Consistent with corporate pyramids generating higher agency costs and information asymmetries between corporate insiders and outside creditors, we find a positive association between the number of investment layers and cost of debt. However, we also find that multi-layered firms mitigate organizational opaqueness through increased financial reporting conservatism, which results in lower cost of debt capital. These findings provide new insights into the relationship between organizational structure and financial reporting quality.     

Development costs and funding of extra care housing

This article reports findings from an indepth evaluation of extra care housing (a form of assisted living positioned between sheltered housing and care homes) for older people in the UK. The information presented is a significant improvement on that previously in the public domain. The authors conclude that a careful reappraisal of cost components and a more integrated approach across housing, health and social care is required, particularly in a climate of public funding cuts.
