An empirical analysis of marginal conditional stochastic dominance

Stochastic dominance is a more general approach to expected utility maximization than the widely accepted mean–variance analysis. However, when applied to portfolios of assets, stochastic dominance rules become too complicated for meaningful empirical analysis, and, thus, its practical relevance has been difficult to establish. This paper develops a framework based on the concept of Marginal Conditional Stochastic Dominance (MCSD), introduced by Shalit and Yitzhaki (1994), to test for the first time the relationship between second order stochastic dominance (SSD) and stock returns. We find evidence that MCSD is a significant determinant of stock returns. Our results are robust with respect to the most popular pricing models.     

Leadership integrity and the role of human resource management in Greece: Gatekeeper or bystander?

With ethical misconduct commonplace in organizations and with the touting of competitive advantage associated with ethical organizational practices, considerable attention has turned to leadership integrity. Leaders are uniquely situated to influence the behavior of organizational members, and integrity has been shown to be instrumental in supporting ethical behavior and decision‐making. This article explores the role and influence of human resources management (HRM) in supporting leadership integrity among a group of large organizations operating in crisis‐stricken Greece. Although the institutional and cultural context of Greece appears to exacerbate role tensions confronted by human resources (HR) professionals, its forces are not deterministic; findings from in‐depth interviews with 12 HR directors indicate that the HR potential to secure ethical influence at the top level is primarily contingent on the nature of the organization's culture. Cultures of integrity enable HR executives to influence integrity and ethical behavior in top management teams (TMTs). In contrast, compliance‐based organizational cultures appear to breed a fickle HR presence: fostering integrity and ethical behavior for the middle and lower levels of an organization, while turning a blind eye to integrity violations at the top.     

Excess corporate payouts and financial distress risk

Firms that follow excessive payout policies (over-payers) are higher on the financial distress spectrum and have lower survival rates than under-payers. In addition, over-payers endure lower future sales and asset growth than under-payers and experience negative abnormal returns in the bond and stock markets. Exogenous import tariff reductions and commodity price jumps reduce the likelihood of overpayment. We interpret this as evidence consistent with financial flexibility considerations, rather than risk-shifting, explaining the decision to overpay. We also find that CEO overconfidence and catering incentives affect overpayment.     

Sustainability reporting,materiality, and accountability assessment in the airport industry

Air travel is, nowadays, recognized as being one of the most popular modes of transport. Air transport is among the most significant contributors to the world gross domestic product and is accountable for a great environmental and social impact. Driven by the well‐established sustainability discourse and the vital role businesses can play in disseminating the sustainable development concept, this paper attempted to map airport industry's most material operational aspects and assess airport operators' accountability level on disclosing corporate information regarding airports' economic, environmental, and social performance. In this context, 33 reports and 903 material issues representing 193 international airports were reviewed and assessed, and a methodology for benchmarking the accountability level of best reporting airport operators was developed, showcasing materiality assessment as a useful management tool for strengthening airport operators' business strategy and enhancing their corporate performance. The paper indicated that (a) customer focus (i.e., health, safety and satisfaction), economic viability, and business continuity and preparedness are operational aspects of high materiality and (b) the disclosure level, especially concerning specific performance indicators, is still moderate. In conclusion, this study has shown that materiality assessment gains ground as a management tool among airports' management teams and the completeness of Sustainability reports is positively correlated with the “level” of adherence as described by the Global Reporting Initiative.     

Consumer Trends and Attitudes to Functional Foods

Abstract

Consumers' needs have grown to such an extent that they are sought out of nutritious and pleasant organoleptic foods, as well as functional foods. This study explores consumer attitudes towards health nutrition products and particularly functional foods, using data from a survey to 325 consumers. The results designate that consumers recognize different kinds of functional foods, willing to pay a premium for their purchase. They perceive that functional foods may contribute to easily follow a healthy and balanced diet and reduce the risk of health problems but appeared anxious about the health benefits these foods communicate in their labelling.     

Trade uncertainties and the hedging abilities of Bitcoin

In this paper, we first estimate the monthly realised correlation, based on daily data, between stock returns of the United States (US) and Bitcoin returns. Then, we relate the realised correlation over the period October 2011 to May 2019 with a news-based measure of the growth of trade uncertainty of the US. Our results show that the realised correlation is negatively impacted by increases in trade uncertainty, which continues to hold under alternative robustness checks, suggesting that Bitcoin can act as a hedge relative to the conventional stock market in the wake of heightened trade policy-related uncertainties, and provide diversification benefits for investors.     

SKILLS MISMATCH: CONCEPTS,MEASUREMENT AND POLICY APPROACHES

The term skills mismatch is very broad and can relate to many forms of labour market friction, including vertical mismatch, skill gaps, skill shortages, field of study (horizontal) mismatch and skill obsolescence. In this paper, we provide a clear overview of each concept and discuss the measurement and inter‐relatedness of different forms of mismatch. We present a comprehensive analysis of the current position of the literature on skills mismatch and highlight areas which are relatively underdeveloped and may warrant further research. Using data from the European Skills and Jobs Survey, we assess the incidence of various combinations of skills mismatch across the EU. Finally, we review the European Commission's country‐specific recommendations and find that skills mismatch, when referring to underutilized human capital in the form of overeducation and skills underutilization, receives little policy attention. In cases where skills mismatch forms part of policy recommendations, the policy advice is either vague or addresses the areas of mismatch for which there is the least available evidence.     

The pricing of audit and non-audit services in a regulated environment: a longitudinal study of the UK life insurance industry

This paper studies the relationship between audit and non-audit service fees paid to the statutory auditor by UK life insurance firms, utilising an extensive panel-data sample set for the period 1999–2009. Consistent with a knowledge spillover (impairment of independence) hypothesis, we predict and find that audit fees are positively (negatively) associated with actuarial (tax service) fees. Additionally, our results indicate that regulatory changes enforced after 2004 deterred UK life insurance firms from purchasing non-audit services that are perceived to impair auditor independence. Finally, we find evidence concerning the inter-temporal determination of audit fees.
