Social Thinking about Collective Risk: How Do Risk‐related Practice and Personal Involvement Impact Its Social Representations?

The study investigates the effects of personal involvement in a collective risk on the structure of its social representation, and how those effects depend on risk‐related experience. The paper reports an empirical study conducted within the structural approach to the Social Representations Theory. We tested the effects of risk‐related practice (earthquake experience) and of personal involvement in risk on the structure of its social representation. The results showed that the social representation was normative in nature, but became more practically oriented in the group who experienced earthquake. A normative representation is useful in judging risk's attributes; instead, a more functional, or a more practically oriented representation is expected to enable the use of more diversified risk‐related information especially for practical purposes (risk mitigation behaviour). Similarly, the social representation of participants who were highly involved in seismic risk was more structured and more practically oriented. However, this was true only if they possessed risk‐related experience, either through collective (risk culture) or live earthquake experience. Based on these results, a suggestion is made on how to increase the efficiency of prevention campaigns that aim at encouraging collective risk‐mitigation conduct.     

Leader‐Member Exchange,Group‐ and Individual‐Level Procedural Justice and Reactions to Performance Appraisals

Previous research has established that relationships with authority figures and procedural justice perceptions are important in terms of the way in which employees react to organizational procedures that affect them. What is less clear are the reasons why exchange quality with authorities is related to perceptions of process fairness and the role of procedural justice climate in this process. Results indicate that individual‐level perceptions of procedural justice, but not performance ratings, partially mediate the relationship between exchange quality and reactions to performance appraisals, and that procedural justice climate is positively related to perceptions of procedural justice and appraisal reactions. These results support a more relational than instrumental view of justice perceptions in organizational procedures bound by exchange quality with an authority figure. Our study suggests that it is essential for managers to actively monitor and manage employee perceptions of process fairness at the group and individual levels. © 2015 Wiley Periodicals, Inc.     

Iterative Project Processes Within Temporary Multi‐Organizations in Construction: The Self‐, Eco‐, Re‐Organizing Projects

Theory‐based studies claim that informal processes interfere with the formal mechanisms and structures of projects in the construction sector. These processes structure and transform multi‐organizations. This four‐year case study reveals empirical evidence about how processes effectively evolve over time and affect formal mechanisms and structures. The results show: (1) the significant differences between what is planned and what actually unfolds in project processes; (2) how iterative processes overshadow linear ones; (3) how informality and “iterativity” eventually end up as self‐, eco‐, and re‐organizing projects and organizations, confirming that projects (re)create the very processes and structures that initiate them.     

L’Évaluation économique de l'investissement dans la conservation des sols: Le cas des aménagements antiérosifs dans le bassin versant du lac Lagdo au Cameroun

This article presents an analysis of the economic impact of erosion control facilities on farm operations in the watershed of Lake Lagdo in Cameroon. Over the past several decades, erosion control facilities, which are erosion control techniques, have been introduced in Cameroon. No assessment of the impacts of these on farm operations had yet been made. Drawing on data from a survey carried out in 2007 and 2008 and a switching regression model, the study concentrates on the effectiveness of the production factors of parcels of land with and without erosion control facilities. The comparison of the average crop yields of the operations in our sample that either adopted or did not adopt such facilities shows a significant difference, representing up to 10% of the value of the farm production. Proof of a positive selection bias is also found, indicating that the farms with above‐average crop yields are more likely to adopt erosion control facilities. Such facilities on the parcels of land also provide an advantage in terms of increasing the productivity of inputs. The analytical approach developed and the positive conclusion of the selection bias can be pertinent to assessing other soil conservation technologies promoted in the area.     

Pro-environmental behaviors for thee but not for me: Green giants,green Gods,and external environmental locus of control

Understanding consumers' allocation of environmental responsibility to external forces (i.e., those perceived to be beyond their direct control) is important yet under-researched. This paper examines how these external attributions affect consumers' pro-environmental behaviors (PEBs). A model of external environmental locus of control (i.e., external-ELOC) is tested, consisting of two superordinate dimensions: powerful-others (encapsulating corporate and government responsibility facets) and chance/fate (incorporating God/higher-power and natural earth-cycle facets). The two higher-order factors negatively associate; such that consumers ascribing environmental responsibility to powerful-others engage in PEBs; whereas those attributing environmental change to chance/fate typically do not. The results inform practical and public policy implications; pinpointing ways for corporations and governments to target their pro-environmental efforts and to sway consumers who share in the ecological burden.     

Parental style and consumer socialization among adolescents: A cross-cultural investigation

The paper examines how parental style affects consumer socialization in a cross-national context, focusing on family communication orientation, adolescents' use of influence strategies, susceptibility to peer influence, and impulse buying tendency. Multiple-informant data from each family (i.e., father, mother, and adolescent) are used in the analysis. The findings suggest that Chinese adolescents, compared with their Canadian counterparts, use less bilateral influence strategies (reasoning, bargaining), but more unilateral influence strategies (playing on emotions, stubborn persuasion); they are also less susceptible to peer influence, and have less impulse buying tendency. Across both cultures, authoritarian parents are more socio-oriented than authoritative, permissive, and neglectful parents, whereas authoritative and permissive parents are more concept-oriented than authoritarian and neglectful parents. Furthermore, adolescents with authoritative and permissive parents more likely use bilateral influence strategies than those with authoritarian parents, while adolescents with neglectful parents use more unilateral influence strategies than those with other parental styles. These findings provide novel insights on market segmentation and international marketing practices.     

Reverse stress testing: Scenario design for macroprudential stress tests

We propose a systematic algorithmic reverse-stress testing methodology to create “worst case” scenarios for regulatory stress tests by accounting for losses that arise from distressed portfolio liquidations. First, we derive the optimal bank response for any given shock. Then, we introduce an algorithm which systematically generates scenarios that exploit the key vulnerabilities in banks' portfolio holdings and thus maximize contagion despite banks' optimal response to the shock. We apply our methodology to data of the 2016 European Banking Authority (EBA) stress test, and design worst case scenarios for the portfolio holdings of European banks at the time. Using spectral clustering techniques, we group 10,000 worst-case scenarios into twelve geographically concentrated families. Our results show that even though there is a wide range of different scenarios within these 12 families, each cluster tends to affect the same banks. An “Anna Karenina” principle of stress testing emerges: Not all stressful scenarios are alike, but every stressful scenario stresses the same banks. These findings suggest that the precise specification of a scenario is not of primal importance as long as the most vulnerable banks are targeted and sufficiently stressed. Finally, our methodology can be used to uncover the weakest links in the financial system and thereby focus supervisory attention on these, thus building a bridge between macroprudential and microprudential stress tests.     

Creativity over time and space

Creativity is often highly concentrated in time and space, and across different domains. What explains the formation and decay of clusters of creativity? We match data on notable individuals born in Europe between the eleventh and the nineteenth centuries with historical city data. The production and attraction of creative talent is associated with city institutions that protected economic and political freedoms and promoted local autonomy. Instead, indicators of local economic conditions such as city size and real wages, do not predict creative clusters. We also show that famous creatives are spatially concentrated and clustered across disciplines, that their spatial mobility has remained stable over the centuries, and that creative clusters are persistent but less than population.

     

Pro-cyclicality beyond business cycle

We show that pro-cyclicality is inherent in risk measure estimates based on historical data. Taking the example of VaR, we show that the empirical VaR measure is mean-reverting over a 1-year horizon when the portfolio is held fixed. It means that a capital requirement rule based on historical measurements of VaR tends in calm times to understate future required capital and tends in volatile times to overstate it. To quantify this pro-cyclicality, we develop a simple and efficient methodology, which we apply to major equity market indices. We make the interesting point that the pro-cyclicality property holds true even in a world with constant volatility, though the empirical magnitude of the mean-reversion is greater than what would be observed in that special case.
