There is an on-going debate as to whether health is negatively affected by economic inequality. Still, we have limited knowledge of the mechanisms relating inequality to individual health and very little evidence comes from less-developed economies. We use individual and multi-level data from Zambia on child nutritional health to test three hypotheses consistent with a negative correlation between income inequality and population health: the absolute income hypothesis (AIH), the relative income hypothesis (RIH) and the income inequality hypothesis (IIH). The results confirm that absolute income positively affects health. For the RIH we find sensitivity to the reference group used. Most interestingly, we find higher income inequality to robustly associate with better child health. The same pattern appears in a cross country regression. To explain the conflicting results in the literature we suggest examining potential mediators such as generosity, food sharing, trust and purchasing power.

Purpose – This chapter gives an overview of meta-analytic methods and illustrates the use of these methods for synthesising research findings. The advantages of performing a meta-analysis are described. Pitfalls in meta-analyses are also discussed. The chapter is intended to present the main elements of a meta-analysis and guide readers to literature presenting meta-analytic methods in greater detail.

Methodology – Key references in the meta-analysis literature are quoted and examples of meta-analyses are presented.

Findings – A meta-analysis is a useful tool for summarising knowledge in fields where a large number of studies have been reported. In addition to providing summary estimates of results, a meta-analysis can be applied to identify factors that produce systematic variation in study findings.

Research implications – Methods of meta-analyses keep developing to deal with complex data structures, thus extending the type of research findings that are amenable to meta-analyses.

Practical implications – Performing a meta-analysis saves labour by eliminating the need to read and digest a large number of studies in order to get an overview of the current state-of-knowledge in a field. Moreover, a meta-analysis establishes a system for easily and quickly updating knowledge as new studies become available.

Purpose: In this chapter, we examine the National Health Service (NHS) and Adult Social Care (ASC) in England, focussing on policies that have been introduced since 2000 and considering the challenges that providers face in their quest to provide a high standard and affordable health service in the near future.

Methodology/Approach: We discuss recent policy developments and published analysis covering innovations within major aspects of health care (primary, secondary and tertiary) and ASC, before considering future challenges faced by providers in England, highlighted by a 2017 UK Parliament Select Committee.

Findings: The NHS and ASC system have experienced tightening budgets and serious financial pressure, with historically low real-terms growth in health funding from central government and local authorities. Policymakers have tried to overcome these challenges with several policy innovations, but many still remain. With large-scale investment and reform, there is potential for the health and social care system to evolve into a modern service capable of dealing with the needs of an ageing population. However, if these challenges are not met, then it is set to continue struggling with a lack of appropriate facilities, an overstretched staff and a system not entirely appropriate for its patients.

Recently, there has been an increase in the number and type of studies in the organizational sciences that examine curvilinear relationships. These studies are important because some relationships have context-specific inflection points that alter their magnitude and/or direction. Although some scholars have utilized basic techniques to make meta-analytic inferences about curvilinear effects with the limited information available about them, there is still a tremendous opportunity to advance our knowledge by utilizing rigorous techniques to meta-analytically examine curvilinear effects. In a recent study, we used a novel meta-analytic approach in an effort to comprehensively examine curvilinear relationships between destructive leadership and followers' workplace outcomes. The purpose of this chapter is to provide an actionable guide for conducting curvilinear meta-analyses by describing the meta-analytic techniques we used in our recent study. Our contributions include a detailed guide for conducting curvilinear meta-analyses, the useful context we provide to facilitate its implementation, and our identification of opportunities for scholars to leverage our technique in future studies to generate nuanced knowledge that can advance their fields.

This chapter aims to evaluate the relationship between the representation of women on corporate boards of directors and its impact on firm financial performance.

This study utilized both a systematic review and a meta-analysis, using a sample of 40 published studies, which gleaned financial indicator and observation data from 28 different countries.

As indicated in previous studies, while positive, there was no significant correlation found between the number of women serving on the boards of directors and firm financial performance.

The heterogeneity between the various studies analyzed may present difficulties in making general conclusions. The chapter could also be subject to publication bias, as the selection criteria included may indicate a need for further peer review. Future meta-analyses should include data associated with other financial indicators.

This study shows how composition ratios of men/women serving on corporate boards should be addressed in terms of proving for a greater diversity of leadership perspectives.

Previous systematic reviews and meta-analyses have analyzed country environments as moderators for the relationship between the representation of women on corporate boards and firm financial performance. The present study evaluates possible differences between the impact of the number of women serving on the board of directors on a variety of financial indicators (ROA, ROE, and Tobin’s Q).

This study explores auditors’ professional attitudes and behaviours. It tests the influence of public interest commitment, independence enforcement beliefs and organisational ethical culture on auditors’ acceptance of and engagement in practices that compromise their objectivity. The study is based on survey responses of 122 Spanish auditors. To analyse the combined effect of the variables under study, variance-based structural equation modelling (partial least squares, PLS) was employed. The results suggest that the regulatory efforts to improve auditors’ behaviours by enforcing independence rules have been internalised by auditors. The results also reinforce the need to instil the societal responsibilities of professional auditors, since auditors’ public interest commitment is related to their ethical decision making. Furthermore, this study reveals that firms’ ethical cultures influence auditors’ commitment to the public interest, as well as their ethical decision making. The study raises practical implications for auditing professionals, regulators and audit firms. Understanding auditors’ beliefs and behavioural patterns is critical to proposing mechanisms that enhance their ethical behaviours, which could ultimately enhance audit quality. The chapter contributes to the field by analysing the combined effect of the regulatory framework and organisational context on auditors’ professional values and behaviours.

Independence is the cornerstone of the auditing profession. Even so, it is often assumed that acquiescing to the audit client when a disagreement occurs is more beneficial to the auditor-client relationship than asserting one’s independence (e.g., see Wang & Tuttle, 2009). We look more closely at the issue in the context of auditor-client management disagreements as recalled by experienced auditors.

We find that for most disagreements in which the auditor did not make any concession at all, the auditor-client relationship was either unaffected or strengthened. We find that a client’s use of pressure tactics did not appear to influence whether or not the auditor made a concession, but that a client’s use of pressure tactics, was associated with damage to the auditor-client relationship. The importance of the issue causing a disagreement was positively associated with the likelihood of the auditor staying with his/her initial position.
