Self-protection and insurance with interdependencies

We study optimal investment in self-protection of insured individuals when they face interdependencies in the form of potential contamination from others. If individuals cannot coordinate their actions, then the positive externality of investing in self-protection implies that, in equilibrium, individuals underinvest in self-protection. Limiting insurance coverage through deductibles or selling “at-fault” insurance can partially internalize this externality and thereby improve individual and social welfare.

Operations Risk Management: Overview of Paul Kleindorfer's Contributions

This paper reviews Paul Kleindorfer's contributions to Operations Management (OM), with a special focus on his research on risk management. An annotated bibliography of selected other contributions reviews the breadth of topics that have occupied Kleindorfer's research attention over his now 45 + years of research. These include optimal control theory, scheduling theory, decision sciences, investment planning and peak load pricing, plus a number of important applications in network industries and insurance. In the area of operations risk management, we review recent work that Kleindorfer and his colleagues in the Wharton Risk Center have undertaken on environmental management and operations, focusing on process safety and environmental risks in the chemical industry. This work is directly related to Kleindorfer's work in the broader area of “sustainable operations”, which he, Kal Singhal and Luk Van Wassenhove recently surveyed as part of the new initiative at POMS to encompass sustainable management practices within the POMS community. Continuing in the area of supply chain risks, the paper reviews Kleindorfer's contributions to the development of an integrated framework for contracting and risk hedging for supply management. The emphasis on alignment of pricing, performance and risk management in this framework is presaged in the work undertaken by Kleindorfer and his co‐authors in the 1980s on after‐sales support services for high‐technology products. This work on supply chain risk, and its successors, is reviewed here in light of its growing importance in managing the unbundled and global supply chains characteristic of the new economy.     

Public meetings as sources of citizen input: Comparing attendees with citizens at large

Although public meetings are the most frequently used method for obtaining citizen input into public decision-making, there is little systematic evidence comparing attendees with citizens at large. This paper addresses this gap in the literature by analyzing results from a series of public meetings and a random-sample telephone survey. The public meetings and telephone survey were conducted in Hillsborough County, Florida to obtain citizen input for the purpose of establishing spending priorities for more than $39 million in federal block grant funds. Findings include representation at public meetings on a number of factors, including race, Hispanic ethnicity, and low-income status. Attendees favor redistributive activities more often than citizens at large; however, both attendees and the general public agree on the importance of funding activities serving certain vulnerable populations, including seniors, persons with disabilities, and victims of domestic violence.     

The Timing of Cohabitation and Engagement: Impact on First and Second Marriages

Using a multistate sample of marriages that took place in the 1990s, this study examined associations between premarital cohabitation history and marital quality in first (N = 437) and second marriages (N = 200) and marital instability in first marriages (intact N = 521, divorced N = 124). For first marriages, cohabiting with the spouse without first being engaged or married was associated with more negative interaction, higher self‐reported divorce proneness, and a greater probability of divorce compared to cohabiting after engagement or marriage (with patterns in the same direction for marital positivity). In contrast, there was a general risk associated with premarital cohabitation for second marriages on self‐reported indices of marital quality, with or without engagement when cohabitation began.     

Multidimensional Family Therapy: A Science‐Based Treatment System

MDFT is a family‐based intervention for adolescent substance abuse and associated mental health and behavioural problems (Liddle, 2010). Integrative in several ways, MDFT uses an ecological or contextual conceptual framework to understand the developmental tasks of teens and their families. Research‐derived knowledge about risk and protective factors, and proximal causes, correlates and contributors to adolescent drug and related problems inform clinical thinking and interventions with every case. A multisystems approach, MDFT assesses and intervenes in four areas: (1) the adolescent as an individual and a member of a family and peer network; (2) the parent(s), both as individual adults and in his or her role as mother; father or caregiver; (3) the family environment and family relationships, as manifested in day‐to‐day family transactional patterns; and (4) extrafamilial sources of influence such as peers, school and juvenile justice. Interventions are made within and coordinated across domains. Progress in one area or with one person has implications for and use in others. Individual meetings with parent(s) and teen set the stage for family sessions, and family meetings may offer content and new outcomes that need to be brought to extrafamily meetings with juvenile justice or school personnel. MDFT was developed and tested as a treatment system rather than a one‐size‐fits‐all approach. A treatment system offers different versions of a clinical model that vary according to factors such as clinical sample characteristics (older versus younger adolescents, juvenile justice involved versus no involvement in juvenile justice systems), and treatment parameters (type of clinical setting and treatment dose).     

The relationship between adverse childhood experiences,health and life satisfaction in adults with care experience: The mediating role of attachment

Adverse childhood experiences (ACEs) are associated with a plethora of negative outcomes. Research has also found that adults who were separated from parental care and lived in alternative care settings during childhood have high levels of ACEs and are more likely to have poor outcomes. A growing body of research has supported the importance of attachment as a mechanism underlying the relationship between ACEs and adult wellbeing. However, little work has examined the role that attachment may play in the outcomes of adults who resided in residential and foster care during childhood. The current study examined the role of attachment avoidance and anxiety in the associations between ACEs and mental health, physical health, and life satisfaction in a sample of 529 adults with alternative care experience from 11 nations. Attachment avoidance partially mediated the relationship between ACEs and life satisfaction, mental health, and physical health. Attachment anxiety partially mediated the relationship between ACEs and life satisfaction and mental health, but not physical health. Taken together, the present study suggests that both attachment anxiety and avoidance play important, but unique, roles in understanding the relationship between ACEs and health and wellbeing for adults with care experience. Implications and limitations are discussed.     

Growth versus Distribution: Does the Pattern of Growth Matter?

Despite the fashion for pro‐poor growth, there remains no consensus as to its meaning. This article proposes three possible definitions, and examines the pattern of growth over time and in different world regions. The growth of the poor's income can be broken down into a growth effect and a distribution effect. In 143 growth episodes, it is found that the growth effect dominates. However, in over a quarter of cases changes in distribution played a stronger role than overall growth in increasing income for the poor. Econometric analysis of growth regressions for each population quintile supports the idea that openness benefits everyone, but indicates a robust perverse relationship with governance. There is also evidence of a trade‐off between growth and distribution, suggesting that attention to distribution will be better for the poor than going for growth.     

Developing countries and systemic pension reforms: Reflections on some emerging problems

Since 1981 close to forty countries have introduced systemic pension reforms that have replaced all or part of prior pay‐as‐you‐go (PAYG) schemes with privately managed funded defined contribution (FDC) pillars or systems. However, over the past decade about half of these countries have subsequently cutback on, or entirely eliminated, these FDC schemes. In this article we explore some of the reasons why this reversal is often taking place in developing countries. As part of our analysis we propose a new pension reform typology that goes beyond the commonly used dichotomy between PAYG and pension privatization. We identify and discuss four factors that are of particular relevance to those seeking to understand the pension policy reversals that have been taking place in many developing countries: low pension coverage and incentive incompatibility, triple burden costs, tradeoffs between pension reforms and social pensions, and difficulties with annuitization.     

Missing Data in Sociological Research: An Overview of Recent Trends and an Illustration for Controversial Questions, Active Nonrespondents and Targeted Samples

In an age of telemarketers, spam emails, and pop-up advertisements, sociologists are finding it increasingly difficult to achieve high response rates for their surveys. Compounding these issues, the current political and social climate has decreased many survey respondents’ likelihood of responding to controversial questions, which are often at the heart of much research in the discipline. Here we discuss such implications for survey research in sociology using: a content analysis of the prevalence of missing data and survey research methods in the most cited articles in top sociology journals, a case study highlighting the extraction of meaningful information through an example of potential mechanisms driving the non-random missing data patterns in the Religion Among Academic Scientists dataset, and qualitative responses from non-responders in this same case. Implications are likely to increase in importance given the ubiquitous nature of survey research, missing data, and privacy concerns in sociological research.
