Forecasting Value at Risk and Expected Shortfall Using a Semiparametric Approach Based on the Asymmetric Laplace Distribution

Value at Risk (VaR) forecasts can be produced from conditional autoregressive VaR models, estimated using quantile regression. Quantile modeling avoids a distributional assumption, and allows the dynamics of the quantiles to differ for each probability level. However, by focusing on a quantile, these models provide no information regarding expected shortfall (ES), which is the expectation of the exceedances beyond the quantile. We introduce a method for predicting ES corresponding to VaR forecasts produced by quantile regression models. It is well known that quantile regression is equivalent to maximum likelihood based on an asymmetric Laplace (AL) density. We allow the density's scale to be time-varying, and show that it can be used to estimate conditional ES. This enables a joint model of conditional VaR and ES to be estimated by maximizing an AL log-likelihood. Although this estimation framework uses an AL density, it does not rely on an assumption for the returns distribution. We also use the AL log-likelihood for forecast evaluation, and show that it is strictly consistent for the joint evaluation of VaR and ES. Empirical illustration is provided using stock index data.

Does Religious Attendance Moderate the Connection Between Pornography Consumption and Attitudes Toward Women?

Feminist theory and religious doctrines alike often suggest that pornography alters the attitudes of those who consume it, particularly with respect to how consumers view women. Many would assume that pornography would universally encourage sexism and female objectification, but recent evidence has linked pornography use with more gender egalitarian views. Using data from a large-scale, nationally representative survey, we argue that cognitive dissonance among pornography consumers could alter egalitarian attitudes. We found that those who reported consuming pornography had more egalitarian attitudes than those who did not, but this difference was stronger among those who attended religious services more regularly—those who would be likely to experience dissonance when consuming pornography. This pattern was consistent across the three egalitarian attitudes we examined: attitudes toward women in power, women in the workplace, and abortion. Our results suggest that pornography might foster progressive attitudes among those most likely to hold conservative beliefs.     

Older Adolescents’ Understanding of Participant Rights in the BlackBerry Project,a Longitudinal Ambulatory Assessment Study

For a long‐term, longitudinal study that used BlackBerry smartphones for passive ambulatory assessment among older adolescents, this study focused on three areas of ethical concern: (1) adolescents’ competence to give assent; (2) understanding of confidentiality, the protection of information, and project goals; and (3) awareness of procedures and benefits, and comfort with the research design. One hundred and seventy‐eight participants were 17 and 18 years old (84 girls). Results suggested that participants freely gave consent and understood most, but not all of the informed consent information. Participants reported a high level of satisfaction. Participants showed less understanding of when their confidentiality would be broken and how data would be protected.     

Toward an organic policy sociology

According to many, sociology is facing a crisis of relevance. Of particular concern is sociology's inability to impact policy. Sociologists, who should be the go‐to on major policy issues have been sidelined as other social scientists take up roles as policy advisors. Recent efforts aimed at encouraging public engagement have focused on disseminating research and producing more policy‐relevant knowledge. These are welcome resources, but they reflect a deep ambivalence toward policy sociology and a tendency to conflate participation in public discussions with policy impact. In contrast, this essay draws on recent findings about the power of policy experts to develop an organic policy sociology. Organic policy sociology depends on co‐designing and carrying out research with policymakers with whom we share critical and professional commitments. By working collaboratively with policymakers, sociologists can foster equity‐promoting policy, change how policymakers understand social problems, and improve how citizens experience policy on the ground. To that end, I offer six orienting strategies for developing and maintaining organic policy sociology projects, from finding the right partner to assessing the impact of our work.     

Gender composition and share of management: Tipping points in US workplaces, 1980–2005

This paper examines how concepts of gendered organizations, tokenism and the glass escalator affect women’s share of management. Specifically, we examine how the gender composition of workplaces affects women’s share of management in 195,534 workplaces using EEO-1 report data collected from the US Equal Employment Opportunity Commission from 1980 until 2005. The EEO-1 data allow us to explore the effects of gender composition on women’s share of management net of labor market change, industrial change, organizational determinants, and changes in workplace segregation using workplace-level data. We draw on past research to identify potential composition levels—tipping points—in which women have more or less share of management. Our findings suggest that across all compositions, ranging from women comprising less than 15% to over 85% of the workplace, larger percentages of the non-management women are associated with greater shares of women in management. Findings offer little support for the glass escalators hypothesis extended to workplaces, but once further contextualized, the findings do suggest that workplaces are gendered in such a way that tokenism works differently for men and women. Thus, our paper adds to the body of research on gender composition and further illustrates the need to determine under which conditions these social processes operate.

Widening the gap: White ignorance,race relations and the consequences for Aboriginal people in Australia

White ignorance has a critical impact on race relations and is implicated in the maintenance of Aboriginal disadvantage. Addressing this ignorance is a largely overlooked capacity-building opportunity within Australia's non-Aboriginal population. It warrants consideration as a key component of strategies targeting Aboriginal disadvantage. Despite the established links between race relations and Aboriginal well-being, Aboriginal perspectives on non-Aboriginal people rarely feature in public discourse on “Aboriginal problems.” This paper draws on data from 180 in-depth interviews with 44 Aboriginal people in Darwin on the topic of White Australian people, culture and race relations. It reports Aboriginal perceptions of White Australian ignorance across areas of great symbolic and practical significance to Aboriginal people's lives. Their experience is that most White Australians are ignorant of the history of colonisation and the complexities of its aftermath. They are ignorant of Aboriginal law, cultures and languages, and of the extent of their own ignorance. The call to address White ignorance subverts assumptions about whose ignorance and capacity must be dealt with in order to progress national goals of reconciliation, address Aboriginal disadvantage and achieve justice and equality for Aboriginal people.

Solving the Economic Lot-Scheduling Problem Using the Method of Prime Subperiods

In recent years the reported successes of Japanese production systems, particularly the just-in-time approach to inventory control, has caused managers to focus more of their attention on efficient decision-making procedures for determining production schedules that minimize inventory costs. One such potential area of attention is the economic lot-scheduling problem (ELSP), which occurs in a variety of manufacturing environments where machining operations are prevalent. The economic lot-scheduling problem addresses the determination of lot sizes for N products with constant demand (and cycled through one machine with a given production rate) to minimize setup and inventory costs. The most successful solution approaches to the ELSP have been based on the concept of a basic period that is of sufficient length for the production of all items, even though each item might not be produced during each repetition of the basic period. This paper proposes a heuristic approach to the solution of the ELSP (referred to as the method of prime subperiods), which is an extension of the basic period approaches. The procedure is described and demonstrated via an example and then tested using a set of six example problems previously employed in the literature related to the ELSP. The results indicate as good or superior performance by the proposed method of prime subperiods.
