As overconsumption has negative effects on ecological balance, social equality, and individual well-being, reducing consumption levels among the materially affluent is an emerging strategy for sustainable development. Today's youth form a crucial target group for intervening in unsustainable overconsumption habits and for setting the path and ideas on responsible living. This article explores young people's motivations for engaging in three behavioural patterns linked to anti-consumption (voluntary simplicity, collaborative consumption, and living within one's means) in relation to sustainability. Applying a qualitative approach, laddering interviews reveal the consequences and values behind the anti-consumption behaviours of young people of ages 14 to 24 according to a means-end chains analysis. The findings highlight potential for and the challenges involved in motivating young people to reduce material levels of consumption for the sake of sustainability. Related consumer policy tools from the fields of education and communication are identified. This article provides practical implications for policy makers, activists, and educators. Consumer policies may strengthen anti-consumption among young people by addressing individual benefits, enabling reflection on personal values, and referencing credible narratives. The presented insights can help give a voice to young consumers, who struggle to establish themselves as key players in shaping the future consumption regime.
Worth the pain?

How do exporting firms react to sanctions? Specifically, which firms are willing — or capable — to serve the market of a sanctioned country? We investigate this question for four sanctions episodes using monthly data on the universe of French exporting firms. We draw on recent econometric advances in the estimation of dynamic fixed effects binary choice models. We find that the introduction of new sanctions in Iran and Russia significantly lowered firm-level probabilities of serving these sanctioned markets, while the (temporary) lifting of the U.S. sanctions on Cuba and the removal of sanctions against Myanmar had no or only small trade-inducing effects, respectively. Additionally, the impact of sanctions is very heterogeneous along firm dimensions and by case particularities. Firms that depend more on trade finance instruments are more strongly affected, while prior experience in the sanctioned country considerably softens the blow of sanctions, and firms can be partly immune to the sanctions effect if they are specialized in serving “crisis countries”. Finally, we find suggestive evidence for sanctions avoidance by exporting indirectly via neighboring countries.
In the copyright industries of the 21st century, metadata is the grease required to make the engine of copyright run smoothly and powerfully for the benefit of creators, copyright industries and users alike. However, metadata is difficult to acquire and even more difficult to keep up to date as the rights in content are mostly multi-layered, fragmented, international and volatile. This article explores the idea of a neutral metadata search and enhancement tool that could constitute a buffer to safeguard the interests of the various proprietary database owners and avoid the shortcomings of centralised databases.
The organic market is characterized by remarkable disparities, and confusion persists about which motives drive organic consumption. To understand them, this research introduces the idea that the same consumer motives can exert different and potentially opposite impacts when organic consumption patterns unfold. The proposed multistage theory of differential effects distinguishes a participation stage, when consumers decide whether to purchase organic at all, and an expenditure stage, when consumers decide about how much of their budget to spend on organic products across purchases. An analysis of shopping patterns of approximately 14,000 households confirms the proposed differential influences: Other-oriented motives (care for others and the environment) support participation but impede sustained expenditures. Only self-oriented motives (hedonism) foster both participation and expenditures. The results pinpoint the need to rethink organic consumption as a stage-specific problem, which opens up new perspectives for managers about an old but persistent problem.
Welfare beyond consumption
(2020)
In developed regions worldwide, so-called anti-consumers are increasingly resisting high-level consumption lifestyles or shifting to alternative forms of consumption. A general reduction in consumption levels is considered necessary to attain global sustainability goals. However, knowledge regarding the factors driving people to deliberately consume less and how anti-consumption affects individuals' well-being is limited. Against this background, this study considers the influence of human values and the well-being effects of two types of anti-consumption: voluntary simplicity and collaborative consumption. Based on representative data from the US (N = 1075) and Germany (N = 1070), the findings show that the two anti-consumption types do not reduce the well-being of individuals' but in some cases, even improve it, which suggests that lowering consumption can not only help protect environmental resources but also serve the greater good of society. In particular, this relationship holds among collaborative consumers with a strong need for cognition, i.e., a cognitive thinking style that involves a high level of decision control. According to the study results, opposite value orientations are the drivers of voluntary simplicity and collaborative consumption (i.e., a focus on self-transcendence versus self-enhancement). These findings are comparable in both countries; however, the strength of the effects differs.
Für die Transformation der industriellen Fertigung stellt die Integration der Realwelt und die parallele Abbildung in der Digitalwelt eine wichtige Anforderung dar. Hier greift das Konzept des digitalen Zwillings zur digitalen Repräsentation physischer Objekte. Zur Verbesserung der Mensch-Maschinen-Interaktion zwischen Fabrikpersonal, Anlagen sowie Werkstücken und Steigerung der Transparenz am Shopfloor, kann ein solcher digitaler Zwilling relevante Daten liefern. In diesem Beitrag wird ein Konzept zur Visualisierung des digitalen Zwillings mittels Augmented Reality vorgestellt und evaluiert.
Verwaltung im Lockdown
(2020)
Die Corona-Pandemie hat im Frühjahr 2020 auch die öffentliche Verwaltung gezwungen, die Arbeit zu einem großen Teil ins Homeoffice zu verlagern. Dieser Beitrag stellt die Ergebnisse einer Studie vor, die mittels qualitativer Interviews und einer Online-Befragung (N=1.189) Beschäftigte öffentlicher Organisationen zum Umgang mit der Krise und den Erfahrungen mit dem Homeoffice befragt hat.
The sharing economy gains momentum and develops a major economic impact on traditional markets and firms. However, only rudimentary theoretical and empirical insights exist on how sharing networks, i.e., focal firms, shared goods providers and customers, create and capture value in their sharing-based business models. We conduct a qualitative study to find key differences in sharing-based business models that are decisive for their value configurations. Our results show that (1) customization versus standardization of shared goods and (2) the centralization versus particularization of property rights over the shared goods are two important dimensions to distinguish value configurations. A second, quantitative study confirms the visibility and relevance of these dimensions to customers. We discuss strategic options for focal firms to design value configurations regarding the two dimensions to optimize value creation and value capture in sharing networks. Firms can use this two-dimensional search grid to explore untapped opportunities in the sharing economy.
Objective We propose a data-driven method to detect temporal patterns of disease progression in high-dimensional claims data based on gradient boosting with stability selection. Materials and methods We identified patients with chronic obstructive pulmonary disease in a German health insurance claims database with 6.5 million individuals and divided them into a group of patients with the highest disease severity and a group of control patients with lower severity. We then used gradient boosting with stability selection to determine variables correlating with a chronic obstructive pulmonary disease diagnosis of highest severity and subsequently model the temporal progression of the disease using the selected variables. Results We identified a network of 20 diagnoses (e.g. respiratory failure), medications (e.g. anticholinergic drugs) and procedures associated with a subsequent chronic obstructive pulmonary disease diagnosis of highest severity. Furthermore, the network successfully captured temporal patterns, such as disease progressions from lower to higher severity grades. Discussion The temporal trajectories identified by our data-driven approach are compatible with existing knowledge about chronic obstructive pulmonary disease showing that the method can reliably select relevant variables in a high-dimensional context. Conclusion We provide a generalizable approach for the automatic detection of disease trajectories in claims data. This could help to diagnose diseases early, identify unknown risk factors and optimize treatment plans.
Urban air mobility
(2021)
The growing global demand for efficient and sustainable urban mobility in metropolitan areas has created innovative approaches to new modes of transportation and vehicles. Using the Delphi method, this study explored the prospective development of urban air mobility (UAM), specifically the emergence of air taxis or vertical take-off and landing (VTOLs). The two-staged study examined 25 projections regarding technological and infrastructural aspects to propose a future scenario for UAM and air taxis for the next 5-10 years. The questioned experts confirmed most of the proposed statements from both areas but were undetermined regarding certain technological aspects. Considering the crucial impacts of regulation and certification as well as consumer perception and acceptance for UAM and air taxis, further research on these topics and their correlation is suggested.
