Work processes, services, or products must be sensibly adapted to changing times. To be able to analyze and, if necessary, adapt creativity in work processes, a precise understanding of these creative activities is necessary. Process modeling techniques are often used to capture business processes, represent them graphically and analyze them for adaptation possibilities. This has been very limited for creative work. An accurate understanding of creative work is subject to the challenge that, on the one hand, it is usually very complex and iterative. On the other hand, it is at least partially unpredictable as new things emerge. How can the complexity of creative business processes be adequately addressed and simultaneously manageable? This dissertation attempts to answer this question by first developing a precise process understanding of creative work. In an interdisciplinary approach, the literature on the process description of creativity-intensive work is analyzed from the perspective of psychology, organizational studies, and business informatics. In addition, a digital ethnographic study in the context of software development is used to analyze creative work. A model is developed based on which four elementary process components can be analyzed: Intention of the creative activity, Creation to develop the new, Evaluation to assess its meaningfulness, and Planning of the activities arising in the process - in short, the ICEP model. These four process elements are then translated into the Knockledge Modeling Description Language (KMDL), which was developed to capture and represent knowledge-intensive business processes. The modeling extension based on the ICEP model enables creative business processes to be identified and specified without the need for extensive modeling of all process details. The modeling extension proposed here was developed using ethnographic data and then applied to other organizational process contexts. The modeling method was applied to other business contexts and evaluated by external parties as part of two expert studies. The developed ICEP model provides an analytical framework for complex creative work processes. It can be comprehensively integrated into process models by transforming it into a modeling method, thus expanding the understanding of existing creative work in as-is process analyses.}, language = {en} } @misc{RitterbuschTeichmann2023, author = {Ritterbusch, Georg David and Teichmann, Malte Rolf}, title = {Defining the metaverse}, series = {Zweitver{\"o}ffentlichungen der Universit{\"a}t Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe}, journal = {Zweitver{\"o}ffentlichungen der Universit{\"a}t Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe}, number = {159}, issn = {1867-5808}, doi = {10.25932/publishup-58879}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-588799}, pages = {12368 -- 12377}, year = {2023}, abstract = {The term Metaverse is emerging as a result of the late push by multinational technology conglomerates and a recent surge of interest in Web 3.0, Blockchain, NFT, and Cryptocurrencies.

They are expected to impact all areas in companies and will, therefore, most likely occur in business negotiations. Although several studies address future developments of different business divisions, the megatrends' impact on negotiations has, thus far, not been analyzed. We designed a model including the three megatrends, i.e., globalization and economic shift, digitalization and new technologies, and demographic and social change, which have main effects on specific negotiation aspects. Our study combined an online survey and expert interviews with negotiation practitioners to provide a first broad view of how megatrends affect future business negotiations. The results confirm our model and reveal a close connection of megatrends and single negotiation aspects. Among others, we examine an orientation toward global partners, an increased interconnection through various electronic systems, as well as two opposite relationship directions - long-term and integrative through strategic cooperation vs. short-term and distributive through competition and new technologies.}, language = {en} } @phdthesis{Baum2023, author = {Baum, Katharina}, title = {Social networking sites}, school = {Universit{\"a}t Potsdam}, pages = {281}, year = {2023}, language = {en} } @article{FranksKalkuhlLessmann2023, author = {Franks, Max and Kalkuhl, Matthias and Lessmann, Kai}, title = {Optimal pricing for carbon dioxide removal under inter-regional leakage}, series = {Journal of environmental economics and management}, volume = {117}, journal = {Journal of environmental economics and management}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1096-0449}, doi = {10.1016/j.jeem.2022.102769}, year = {2023}, abstract = {Carbon dioxide removal (CDR) moves atmospheric carbon to geological or land-based sinks. In a first-best setting, the optimal use of CDR is achieved by a removal subsidy that equals the optimal carbon tax and marginal damages. We derive second-best policy rules for CDR subsidies and carbon taxes when no global carbon price exists but a national government implements a unilateral climate policy. We find that the optimal carbon tax differs from an optimal CDR subsidy because of carbon leakage and a balance of resource trade effect. First, the optimal removal subsidy tends to be larger than the carbon tax because of lower supply-side leakage on fossil resource markets. Second, net carbon exporters exacerbate this wedge to increase producer surplus of their carbon resource producers, implying even larger removal subsidies. Third, net carbon importers may set their removal subsidy even below their carbon tax when marginal environmental damages are small, to appropriate producer surplus from carbon exporters.}, language = {en} } @article{SurethKalkuhlEdenhoferetal.2023, author = {Sureth, Michael and Kalkuhl, Matthias and Edenhofer, Ottmar and Rockstr{\"o}m, Johan}, title = {A welfare economic approach to planetary boundaries}, series = {Jahrb{\"u}cher f{\"u}r National{\"o}konomie und Statistik}, volume = {243}, journal = {Jahrb{\"u}cher f{\"u}r National{\"o}konomie und Statistik}, number = {5}, publisher = {De Gruyter Oldenbourg}, address = {Berlin}, issn = {0021-4027}, doi = {10.1515/jbnst-2022-0022}, pages = {477 -- 542}, year = {2023}, abstract = {The crises of both the climate and the biosphere are manifestations of the imbalance between human extractive, and polluting activities and the Earth's regenerative capacity. 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.}, language = {en} } @article{BaeumlMarcusSiedler2023, author = {B{\"a}uml, Matthias and Marcus, Jan and Siedler, Thomas}, title = {Health effects of a ban on late-night alcohol sales}, series = {Health economics}, volume = {32}, journal = {Health economics}, number = {1}, publisher = {Wiley}, address = {New York, NY}, issn = {1099-1050}, doi = {10.1002/hec.4610}, pages = {65 -- 89}, year = {2023}, abstract = {This paper studies the impact of a ban on late-night off-premise alcohol sales between 10 p.m. and 5 a.m. in Germany. We use three large administrative data sets: (i) German diagnosis related groups-Statistik, (ii) data from a large social health insurance, and (iii) Road Traffic Accident Statistics. Applying difference-in-differences and synthetic-control-group methods, we find that the ban had no effects on alcohol-related road casualties, but significantly reduced alcohol-related hospitalizations (doctor visits) among young people by around 9 (18) percent. The decrease is driven by fewer hospitalizations due to acute alcohol intoxication during the night—when the ban is in place—but not during the day.}, language = {en} } @article{FleischerBuzogany2023, author = {Fleischer, Julia and Buzog{\´a}ny, Aron}, title = {Unboxing international public administrations}, series = {The American review of public administration}, volume = {53}, journal = {The American review of public administration}, number = {1}, publisher = {Sage}, address = {Thousand Oaks, Calif.}, issn = {0275-0740}, doi = {10.1177/02750740221136488}, pages = {23 -- 35}, year = {2023}, abstract = {Recent debates in international relations increasingly focus on bureaucratic apparatuses of international organizations and highlight their role, influence, and autonomy in global public policy. In this contribution we follow the recent call made by Moloney and Rosenbloom in this journal to make use of "public administrative theory and empirically based knowledge in analyzing the behavior of international and regional organizations" and offer a systematic analysis of the inner structures of these administrative bodies. Changes in these structures can reflect both the (re-)assignment of responsibilities, competencies, and expertise, but also the (re)allocation of resources, staff, and corresponding signalling of priorities. Based on organizational charts, we study structural changes within 46 international bureaucracies in the UN system. Tracing formal changes to all internal units over two decades, this contribution provides the first longitudinal assessment of structural change at the international level. We demonstrate that the inner structures of international bureaucracies in the UN system became more fragmented over time but also experienced considerable volatility with periods of structural growth and retrenchment. The analysis also suggests that IO's political features yield stronger explanatory power for explaining these structural changes than bureaucratic determinants. We conclude that the politics of structural change in international bureaucracies is a missing piece in the current debate on international public administrations that complements existing research perspectives by reiterating the importance of the political context of international bureaucracies as actors in global governance.}, language = {en} } @article{KapidzicFreyNeubergeretal.2023, author = {Kapidzic, Sanja and Frey, Felix and Neuberger, Christoph and Stieglitz, Stefan and Mirbabaie, Milad}, title = {Crisis communication on Twitter}, series = {International journal of communication}, volume = {17}, journal = {International journal of communication}, publisher = {The Annenberg Center for Communication}, address = {Los Angeles, Calif.}, issn = {1932-8036}, pages = {735 -- 754}, year = {2023}, abstract = {The study explores differences between three user types in the top tweets about the 2015 "refugee crisis" in Germany and presents the results of a quantitative content analysis.
