Planetary boundaries define limits for biophysical systems and processes that regulate the stability and life support capacity of the Earth system, and thereby also define a safe operating space for humanity on Earth. Budgets associated to planetary boundaries can be understood as global commons: common pool resources that can be utilized within finite limits. Despite the analytical interpretation of planetary boundaries as global commons, the planetary boundaries framework is missing a thorough integration into economic theory. We aim to bridge the gap between welfare economic theory and planetary boundaries as derived in the natural sciences by presenting a unified theory of cost-benefit and cost-effectiveness analysis. Our pragmatic approach aims to overcome shortcomings of the practical applications of CEA and CBA to environmental problems of a planetary scale. To do so, we develop a model framework and explore decision paradigms that give guidance to setting limits on human activities. This conceptual framework is then applied to planetary boundaries. We conclude by using the realized insights to derive a research agenda that builds on the understanding of planetary boundaries as global commons.

This study proposes a new approach to understanding extreme events and boom-bust processes in agricultural markets. Using weekly futures data for twelve indexed agricultural commodities during 2006 to 2016, we find that extreme price changes, located in the 10% tails of the distribution, cluster across agricultural markets. We then implement a multinomial logit model to investigate which factors are associated with the propagation of extreme events. Specifically, we disentangle three transmission conduits. (1) The macroeconomic conduit captures the possibility that the synchronized extreme price events are generated by business-cycle driven demand shifts mainly in emerging economies. (2) The financial conduit refers to potential links between extreme returns and the increasing flow of money from financial participants into agricultural futures markets. (3) Finally, the energy conduit accounts for possible spillover effects due to oil price shocks. Our results indicate an important role of managed money positions and oil prices while the real demand channel remains mostly insignificant. (C) 2017 Elsevier Ltd. All rights reserved.

The study assumes that people will only lower their level of consumption if doing so does not also lower personal wellbeing. More precisely, this research investigates how specific subtypes of sustainable anticonsumption (e.g., voluntary simplicity, collaborative consumption, and debt-free living) relate to different states of consumer's wellbeing (e.g., financial, psychosocial, and subjective wellbeing). This work also examines whether consumer empowerment can improve personal wellbeing and strengthen the anticonsumption wellbeing relationship. The results show that voluntarily foregoing consumption does not reduce wellbeing and consumer empowerment plays a significant role in supporting sustainable pathways to consumer wellbeing. This study reasons that empowerment improves consumer sovereignty, but may be detrimental for consumers heavily concerned about debt-free living. The present investigation concludes by proposing implications for public and consumer policymakers wishing to promote appropriate sustainable (anticonsumption) pathways to consumer wellbeing.

They reveal new evidence that building brand equity is a means to mitigate negative effects, and indicate that negative spillover effects within a high-equity brand portfolio are unlikely. Finally, this research identifies situations in which developing a new brand might be more beneficial than leveraging an existing brand.

The need for rapid action by national authorities, the EU and international organisations conflicts with the time-consuming nature of democratic deliberation; short-term political firefighting has given little consideration to the long-term sustainability and time consistency of policies; and decentralised decisions threaten effective synchronisation within multi-level governance systems. This article suggests that democratic politics requires a balance between the temporal characteristics of responsive and responsible politics. The timeframe for responsive politics is shaped by electoral cycles that encourage speedy action; short-term lags between political choices and their effects; and temporal discretion of decision-makers. The timeframe for responsible politics is characterised by time-consuming procedures; solutions that take time to unfold and are sustainable in the longer term; and the purposive synchronisation amongst actors and across policy domains and levels of policy-making. The finely balanced temporal constitution of democracy has been challenged in two fundamental ways. First, as the ability of decision-makers to work within the time limits of their mandates and to respond to the temporal expectations of the electorate decreases, the temporal ties that ensure the responsiveness of political authority to the electorate weaken. Second, the distinct temporal qualities of majoritarian and non-majoritarian institutions that encourage responsibility are called into question. Consequently, political time in Europe runs the risk of becoming both less responsive and less responsible.

T1 - A Procedural Model for the Production of reusable and standard-compliant E-Learning Offerings N2 - Cost-efficient production of high-quality learning contents is an important success factor for a sustainable and economic realisation of E-Learning. This necessitates the design of sustainable production processes, which create reusable Learning Objects and require minimal resources. In such a context, this contribution introduces a practical and business-process oriented Procedural Model for the Production of reusable and standard-compliant E-Learning Offerings. It has been developed and applied in a project that produces learning contents for a Master program of an international virtual university. After the introduction of a reengineering method, a special analysis instrument for E-Learning has been designed to analyse the existing production processes and to improve them in terms of efficiency, costs, standard- compliance, and process automation. The method introduced is hence not focussing on individual technical solutions but on the efficiency of the whole E-Learning production and value chain. It gives an orientation for establishing and maintaining sustainable and competitive E-Learning production processes with appropriate effort.

T1 - A paradox perspective on the interactive effects of visionary and empowering leadership JF - Organizational Behavior and Human Decision Processes N2 - In a multi-source, lagged design field study of 197 leader-follower dyads, we test a model that predicts positive interactive effects of visionary and empowering leadership on follower performance. Based on the paradox perspective, we argue that visionary and empowering leadership are synergistic in that their combination enables leaders to address a key paradox inherent to leader behavior identified by Waldman and Bowen (2016): Maintaining control while simultaneously letting go of control. We argue that visionary leadership addresses the former and empowering leadership addresses the latter pole of this pair of opposites. Hence, in line with paradox thinking, we posit that leaders will engender more positive effects on follower performance when they enact visionary and empowering leadership behaviors simultaneously and adopt a "both-and" approach, rather than focus on one of these behaviors without the other. Our results support our hypothesized interactive effect of visionary and empowering leadership on goal clarity, as well as a conditional indirect effect such that goal clarity mediates the interactive effect of visionary and empowering leadership on individual follower performance.

Our model framework mainly follows Barcena-Ruiz and Garzon (J Econ 80:27-42, 2003) who set up the model with quantity competition. We extend their analysis by analyzing the case of competition in prices. Further we compare the incentives to merge with Bertrand and Cournot competition. Comparing quantity with price competition we can show that a merger is more likely with Cournot competition than with Bertrand competition.

We found little evidence of a congruent local dimension of integration policies. Local policies resemble their national policy frameworks fairly well in terms of policy approaches and domains. Our multi-level perspective shows that this is not the result of top-down hierarchical governance, but rather of a multilevel dynamic of two-way interaction. Local policy legacies and local politics matter and national policies are also influenced by local approaches of integration.

To ensure the competitiveness of manufacturing enterprises the vision for the future figures out cyber-physical production systems (CPPS) as a core component of a modern factory. Adaptability and coping with complexity are (among others) potentials of this new generation of production management. The successful transformation of this theoretical construct into practical implementation can only take place with regard to the conditions characterizing the context of a factory. The subject of this contribution is a concept that takes up the brownfield character and describes a solution for extending existing (legacy) systems with CPS capabilities.

The analysis is based on a static simulation model for the German tax system using income tax micro-data. The data shows that changing the present progressive tax system to a flat-tax, which was proposed by the FDP in 2010, could reduce the tax revenue by 15 billion Euro. Such a tax regime would increase the unequal distribution and polarisation of net incomes. The IW Koln suggested an alternative tax rate in 2008. This regime would increase unequal distribution and polarisation of disposable incomes to a greater extent than the FDP-tax rate. An implementation of this income tax scale would go along with losses in tax revenue of 18.8 billion Euro. Likewise, the implementation of a 2009 SPD tax rate proposal would reduce tax revenue by 14.8 billion Euro. Although this regime would reduce unequal distribution, the effect on the polarization of disposable incomes is not definitely predictable. In contrast to all the other scenarios, the realisation of the recent SPD tax rate proposal from 2011 could enlarge tax revenue by 4.7 billion Euro. This tax regime would reduce unequal distribution and polarisation of disposable incomes even more than the present tax system.

In terms of analytical infrastructures, a highly evolutionary environment causes volatile, time dependent workloads in its components, and intelligent, flexible task distribution between local systems and cloud services is attractive. With the aim of developing a flexible and efficient design for analytical infrastructures, this paper proposes a flexible architecture model, which allocates tasks following a machine-specific decision heuristic.

The increasing acceleration of new developments in media and ICT technologies greatly affected the Creative Industries' dynamic with a direct impact on the people working in this sector. Since only a few studies focus on competences needs, more or less isolated from the trends within the industry, we address the topic of individual competence shifts in the turbulent environment of the Creative Industries. We investigated the trends regarding competence shifts and their implications as well as the competences which are essential for creative professionals. We conducted a broad literature review as well as a qualitative study, which includes interviews and workshops with industry experts on trends within the Creative Industries and corresponding dimensions and demands for competences. We present four requirements that call for shifts in the education of competences. Based on the discussion of requirements, we present a competence portfolio for the Creative Industries along the dimensions of professional, methodological and personal-social competences. The portfolio clearly indicates which competences should be taken into consideration for the development of curricula and study programmes in the education of creative professionals. A generalization of these findings suggests new challenges for companies relying on creative professionals.
