Optimal portfolios under worst-case scenarios

In standard portfolio theories such as Mean–Variance optimization, expected utility theory, rank dependent utility heory, Yaari’s dual theory and cumulative prospect theory, the worst outcomes for optimal strategies occur when the market declines (e.g. during crises), which is at odds with the needs of many investors. Hence, we depart from the traditional settings and study optimal strategies for investors who impose additional constraints on their final wealth in the states corresponding to a stressed financial market. We provide a framework that maintains the stylized features of the SP/A theory while dealing with the goal of security in a more flexible way. Preferences become state-dependent, and we assess the impact of these preferences on trading decisions. We construct optimal strategies explicitly and show how they outperform traditional diversified strategies under worst-case scenarios.     

On the constitution of audit committee effectiveness

Pressures to perform and be effective are significantly influential within contemporary society, including within the realm of corporate boards of directors and audit committees. This paper adopts a social constructivist approach to better understand the process by which meanings regarding audit committee effectiveness are internally developed and sustained, within the small group of people who attend audit committee meetings. We conducted the investigation through interviews in three large Canadian public corporations listed on the Toronto Stock Exchange.     

Actual experience,potential experience or age,and labor force participation by married women

In this paper, the limitations of potential experience and age as proxies for market experience are discussed. Results from a conditional logit model estimating the probability of participation by married women are sensitive to the measure of experience used in the empirical specification. Married women usually have noncontinuous labor market histories so age and potential experience will fall short of actual experience. Direct information about a woman's labor market history is necessary in empirical studies of the market behavior of married women.     

HOUSEWORK VS. MARKETWORK: SOME EVIDENCE HOW THE DECISION IS MADE

Empirical research using the opportunity cost approach to estimating the value of non-market work of women tends to focus on the value of actual or potential output produced at home and expected or actual earnings, and assume that a rational decision involves choosing the higher one. Evidence derived from data on young married women suggests that full-time homemakers frequently are unable to provide estimates either of their potential earnings or of the lowest wage they would accept to enter the labor market, and that such estimates as they do provide are not soundly based. We also found that using wages of women in the labor market to estimate the value of the home time of full-time homemakers involves upward bias. We conclude that there are good reasons for caution in using the opportunity cost approach.     

Technology, markets and the design of women's jobs—the case of the clothing industry

The clothing industry has been saved largely as a result of the introduction of new technology in response to an increasingly competitive market place. But what affect has this restructuring had upon jobs? We explore how women workers have experienced this change and why policy-making should consider job design.     

Optimal Reinsurance Arrangements Under Tail Risk Measures

Regulatory authorities demand insurance companies control their risk exposure by imposing stringent risk management policies. This article investigates the optimal risk management strategy of an insurance company subject to regulatory constraints. We provide optimal reinsurance contracts under different tail risk measures and analyze the impact of regulators' requirements on risk sharing in the reinsurance market. Our results underpin adverse incentives for the insurer when compulsory Value-at-Risk risk management requirements are imposed. But economic effects may vary when regulatory constraints involve other risk measures. Finally, we compare the obtained optimal designs to existing reinsurance contracts and alternative risk transfer mechanisms on the capital market.     

Identity narratives under threat: A study of former members of Arthur Andersen

This paper examines the processes by which individuals work their sense of organizational and professional identity in the aftermath of a professional failure. Drawing on twenty-five interviews carried out with former members of Arthur Andersen who mostly worked for the firm in Canada and the United Kingdom, we investigate interviewees’ identity work ensuing from the breakdown of the firm. Specifically, identity work comprises processes by which individuals reflectively seek to maintain or revise their sense of identification with the AA organization and also with the public accounting profession, along with developing self-understandings regarding causes and consequences ensuing from the firm’s collapse. Our analysis indicates that four interpretive schemes or patterns mainly characterize interviewees’ identity work: disillusion; resentfulness; rationalization; and hopefulness. Each of these patterns can be viewed as conveying a distinct representation of what “truly” happened within AA. In this sense, identity work, sense-making and truth contests are inextricably linked altogether. Moreover, the present paper underlines the pertinence of studying entangled processes of identity work and sense-making in order to better understand how broader social forces or discourses (e.g., commercialization and risk) are experienced and translated by the self in the context of identity-threatening events. That is, the identity work/sense-making nexus constitutes a relevant theoretical anchoring to study the circulation of discourses in society.     

Insurance Market Effects of Risk Management Metrics

We extend the classical analysis on optimal insurance design to the case when the insurer implements regulatory requirements (Value-at-Risk). Presumably, regulators impose some risk management requirement such as VaR to reduce the insurers’ insolvency risk, as well as to improve the insurance market stability. We show that VaR requirements may better protect the insured and improve economic efficiency, but have stringent negative effects on the insurance market. Our analysis reveals that the insured are better protected in the event of greater loss irrespective of the optimal design from either the insured or the insurer perspective. However, in the presence of the VaR requirement on the insurer, the insurer's insolvency risk might be increased and there are moral hazard issues in the insurance market because the optimal contract is discontinuous.
