Qualitative valuation of environmental criteria through a group consensus based on stochastic dominance

This paper introduces a qualitative valuation method to elicit stakeholders' intensities of preferences for a complex environmental issue and multiple social groups. Environmental valuation studies have shown that in any complex environment with a diversity of environmental services, stakeholders have difficulties using a monetary valuation to make trade-offs between different environmental services. Stated preference methods such as the Contingent Valuation Method (CVM) have been criticised for their individualistic format and assumptions of commensurability between environmental criteria. To alleviate both of these criticisms, we propose a qualitative valuation method. The method contains a discursive step to allow stakeholders to discuss and construct a list of environmental criteria and alternative plans. The list of criteria and plans is subsequently used by a group of experts to formulate an Impact Matrix (IM), which is to be used in the succeeding individualistic steps of the methodology. The first individualistic step consists of asking the stakeholders to rank Alternative Impacts (AIs) in the IM for each single criterion. The stakeholders are then asked to express intensities of their preferences through pairwise comparisons between the AIs of the constructed rank order on each single criterion. These intensities are expressed on a qualitative scale. Subsequently, to provide social intensities of preferences, a social preference (social rank order) is first determined for each single criterion. We propose to use the median value among the intensities of preferences as the social intensity of preference by assuming interpersonal comparability and taking into account stochastic monotonocity. This is a pre-processing step, which allows us to reach social intensities of preferences in the Lar rangeland (Iran), where several social groups have conflicting interests on rangeland services, leading to conflicting preferences on environmental criteria.     

Entrepreneurship and innovation in Ghana: enterprising Africa

This study adopts a multi-level theoretical framework to examine data from 496 entrepreneurs in Ghana. Seven types of innovation activity are analysed against three categories of variables: the characteristics of the entrepreneur, the internal competencies of the firm, and firm location. Across all respondents, the incidence of incremental innovation was far greater than novel innovation. The extent of innovation was related to the education level of the entrepreneur. Firm size and involvement in exporting were positively related to innovation, but firm growth is less systematically so. Innovation was greater in firms located in conurbations compared to firms located in large and small towns. We conclude with suggestions for policy to promote entrepreneurship and innovation in Ghana.      

Applied futures research in France : Some critical views

Professor Cazes critically examines the futures studies conducted in France as part of the VIth Plan (1971–1975). He identifies three classes of research—vertical, horizontal and synthetic— and analyses the strengths and weaknesses of each as they relate to policy planning.     

The transition from products to solutions: External business model fit and dynamics

This article provides empirical evidence and contributes to theory building concerning business model fit and dynamics in the area of solutions business. Business models are seen in this context as going beyond considerations such as offerings and internal processes or even relationships, and as including network and market considerations. Indeed the paper highlights the fact that a business model is not firm-focused, nor dyad-focused, but rather network-, and even market-focused, demonstrating that a business model is not static, but dynamic. Manufacturer and customer continuously shift form and content of their respective business models to adapt both to the needs of the counterpart and to market context. A qualitative case study approach is adopted, with subsequent content analysis. The case study relates to the aerospace industry with focus on a complex engineering firm, one of the largest aircraft manufacturers in the world, its customer — a national airline — and their network partners of various kinds. The data were collected through multiple face-to-face interviews with managers in both companies, as a part and parcel of a network of actors that influences and is influenced by the supplier–buyer relationship. Relationships over time between these firms and network partners are described, highlighting the interplay of products and services related to the provision of solutions. Findings highlight the dynamic nature of business models over the relationship lifecycle between supplier and customer in a complex engineering environment, and the need for reciprocal adjustment of models.     

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.     

Margin practices and requirements during the National Banking Era: An early example of macro‐prudential regulation

The New York stock market was plagued by a series of financial crises during the National Banking Era, culminating in the Panic of 1907. The traditional view holds that the crises were rooted in structural flaws related to trade settlement as well as excessive and indiscriminate margin lending that remained unaddressed until the formation of the Federal Reserve Bank. An examination of the historical record, however, shows that brokers sought to control contagion and spillover effects through reform of the settlement process and by modulating margin lending rates and maintenance requirements according to macroeconomic conditions, counterparty credit‐worthiness and market volatility. Using newly gathered archival data, we show that the New York Stock Exchange enacted macro‐prudential regulations that may have reduced the severity of crises during this period. By providing early evidence of private sector responses to rising systemic risk, the paper addresses an important aspect of early market microstructure.     

Organizational Sensemaking of Non-ethical Consumer Behavior: Case Study of a French Mutual Insurance Company

Researchers and managers alike are becoming increasingly interested in the topic of unethical consumer behavior. Where most studies view unethical behavior as something that is identifiable per se, the authors of the present article believe that it only exists because it has been constructed by people operating within a specific context. Hence the efforts made by this paper to explore, at the level of one specific organization, how interactions between employees and consumers might lead to the construct of unethical consumers. Based on a case study of France’s AMDM—a mutual insurance company set up to serve a client base comprising motorcyclists—the paper addresses how one group of consumers ends up being categorized as unethical by revealing the existence of a sensemaking process within the target organization. This process develops in three main phases: the nurturing of a shared ethos; the protection of employees’ recognized status; and the demonization of any group of consumers threatening this status. Managers incorporating this sensemaking process can avoid or mitigate the negative effects befalling organizations when these kinds of unethical consumer behavior are constructed.
