Turning Social Return on Investment on Its Head

This article undertakes a critique of social return on investment (SROI), combining the existing research literature with an analysis of six case studies of supported social enterprises employing people with disabilities and other challenges that affect their access to the conventional labor market. The critique of SROI focuses on its positivist roots and its emphasis on one number, the SROI ratio. It also discusses the technical challenges in producing that number, including concerns about its reliability. The article presents the stakeholder impact statement, an approach that is rooted in interpretivism and attempts to understand the impact of enterprises through the eyes of multiple stakeholders. Unlike SROI, which is a supplement to conventional accounting statements, the stakeholder impact statement integrates financial and social impact data, thereby placing them on the same level of importance.     

基于生态系统的管理如何融入城市环境政策——以西华盛顿为例

全球范围内城市聚落的增长影响着人类对自然资源的管理,从而促使自然科学和社会科学的学者们提倡以基于生态系统的途径来管理人类聚落。尽管过往有不少探讨基于生态系统管理(ecosystem-based management,以下简称EBM)的文献,但在制定环境政策时,却极少有城市和区域规划师将EBM因素考虑在内。本文对西华盛顿州的城市规划师在审视关于环境政策的科研数据时,在多大程度上运用EBM原则进行评估。笔者采用了现成文献中对EBM的定义,采访了42位在西华盛顿工作的环境规划师,询问其在审视有关科研数据时会考虑哪些EBM因素,并对访谈数据进行内容分析。结果显示,规划师们在审视与制定环境政策相关的科学文献时,会考虑监测、机构间合作、生态边界、价值取向乃至适应性管理等因素,但对于尺度、生态完整性和机构改革等因素,则会遇到阻碍或者说不会明确考虑。本文还阐述了为何有些EBM因素得到重视而另一些却被忽略,最后对通过应用EBM原则来改良城市环境政策的制定提出了建议。     

Sourcing Decisions with Competitive Suppliers and Imperfect Information

Manufacturers often must choose between outsourcing and producing internally. This choice is complex and influenced by a variety of factors, including the costs and capabilities of the potential suppliers. In addition, if the manufacturer outsources, he must design the sourcing process. We study the manufacturer's outsourcing decision, with a focus on the impact of the sourcing process on that decision. We consider a setting in which the manufacturer has imperfect information regarding the suppliers' costs and capabilities, and we assume that the manufacturer uses a two‐stage sourcing process. The first stage is the qualification stage, in which the manufacturer seeks to reduce the uncertainty regarding the suppliers' capabilities. The second stage is the supplier selection stage, in which the manufacturer selects among the qualified suppliers on the basis of price. We first characterize the optimal design of the two‐stage process, and then consider the outsourcing decision. We demonstrate several trade‐offs. Vertical integration enables the manufacturer to reduce uncertainty and extract all of the profits of production. However, outsourcing enables the manufacturer to take advantage of the (potentially) lower costs and higher capabilities of the suppliers, particularly if competition between suppliers can be encouraged. We find that the manufacturer is more likely to vertically integrate when the warranty cost and the cost of exerting effort during qualification are large, and when there is significant uncertainty regarding the suppliers' capabilities. The manufacturer is more likely to outsource when the suppliers' costs (capabilities) are low (high), and when the number of suppliers is large.     

Sexual minority youth in romantic relationships: Associations with youth well-being

This study investigated differences in depressive symptoms, loneliness, and self-esteem for monosexual (lesbian, gay) and plurisexual (bisexual, pansexual, queer) sexual minority youth (SMY) by relationship status (single, partnered) and relationship configuration (same-gender partner, different-gender partner). Participants included 338 SMY (M_age = 19.10 years) who reported on their relationship status, partner's gender identity, well-being, and ability to confide in partner about LGBTQ issues. Results indicated that for plurisexual youth, single status was associated with greater loneliness; plurisexual youth with same-gender partners reported fewer depressive symptoms and marginally greater ability to confide in their partner about LGBTQ issues than those with different-gender partners. Findings reveal similarities across SMY while also highlighting some unique challenges among plurisexual youth with different-gender partners.     

Identification and Estimation of a Discrete Game of Complete Information

We discuss the identification and estimation of discrete games of complete information. Following Bresnahan and Reiss (1990, 1991), a discrete game is a generalization of a standard discrete choice model where utility depends on the actions of other players. Using recent algorithms to compute all of the Nash equilibria to a game, we propose simulation‐based estimators for static, discrete games. We demonstrate that the model is identified under weak functional form assumptions using exclusion restrictions and an identification at infinity approach. Monte Carlo evidence demonstrates that the estimator can perform well in moderately sized samples. As an application, we study entry decisions by construction contractors to bid on highway projects in California. We find that an equilibrium is more likely to be observed if it maximizes joint profits, has a higher Nash product, uses mixed strategies, and is not Pareto dominated by another equilibrium.     

Ranked sparsity: a cogent regularization framework for selecting and estimating feature interactions and polynomials

Cognitive reappraisal and need to belong predict prosociality in Mexican-origin adolescents

This 2-year longitudinal study examined Mexican-origin adolescents’ need to belong and cognitive reappraisal as predictors of multiple forms of prosocial behavior (i.e., general, emotional, and public prosocial behaviors). Prosocial behaviors, which are actions intended to benefit others, are hallmarks of social proficiency in adolescence and are influenced by intrapersonal abilities and motivations that typically develop during adolescence. Yet, few studies of Mexican-origin or other U.S. Latinx youths have examined whether such individual difference characteristics, specifically social motivation and emotion regulation skills, support prosocial behavior. In a sample of 229 Mexican-origin youth (M_age = 17.18 years, SD = .42, 110 girls), need to belong, cognitive reappraisal, and general prosocial behaviors were assessed at ages 17 and 19. Emotional and public forms of prosociality also were assessed at age 19. Cognitive reappraisal was positively associated with concurrent general prosociality at age 17, whereas need to belong was positively associated with concurrent public prosociality at age 19. Moderation analyses revealed that general and emotional types of prosocial behaviors at age 19 were lowest for youth with both lower need to belong and less use of cognitive reappraisal at 19 years. Greater cognitive reappraisal skills and need to belong may reflect distinct motivations for engaging in varying forms of prosocial behavior in late adolescence.
