Under rational expectations, we show that a time-consistent policy outcome exists with either a zero carbon tax or a prohibitive carbon tax that leads to zero fossil investments - an "all-or-nothing" policy. Although stranded assets are crucial to such a bipolar outcome, they disappear again under time-consistent policy.

Since the seminal work of Arthur Pigou in 1920, economic theory has analyzed the efficiency gains arising from various instruments that internalize externalities and lead to Pareto-improvements. It is widely recognized in environmental economics that a carbon price would effectively reflect the scarcity of the atmospheric disposal space for carbon depending on the temperature target that is to be achieved. The question of how to organize the transition process, i.e. moving from inefficient to efficient allocations, and implementing the necessary policies, has gained increasing attention in recent years. Arguably, the transition process is tightly interwoven with political processes that include complex interactions between societal stakeholders, such as households and firms, on the one hand, and political decision makers, on the other. Accordingly, understanding political-economy aspects of the transition process, including distributional outcomes, is becoming increasingly relevant. While a growing literature discusses the distributional implications of climate policy on households, it is less well understood how asset owners might be affected by climate policy and how these potential impacts would interact with the transition process. This Special Section focuses on public policy challenges related to this transition problem, with special emphasis on asset owners. A core theme is the special role of stranded assets, i.e. a devaluation of capital stocks or financial assets either by introducing a stringent carbon price or by omitting a pre-announced policy of this kind.}, language = {en} } @article{KalkuhlWenz2020, author = {Kalkuhl, Matthias and Wenz, Leonie}, title = {The impact of climate conditions on economic production}, series = {Journal of Environmental Economics and Management}, volume = {103}, journal = {Journal of Environmental Economics and Management}, publisher = {Elsevier}, address = {San Diego}, issn = {0095-0696}, doi = {10.1016/j.jeem.2020.102360}, pages = {20}, year = {2020}, abstract = {We present a novel data set of subnational economic output, Gross Regional Product (GRP), for more than 1500 regions in 77 countries that allows us to empirically estimate historic climate impacts at different time scales.

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.

We incorporate two related explanations, yet commonly used in different fields of literature, to explain public sector choice. First, following social learning theory, we hypothesize that parents serve as role models and thereby affect their children's sector choice. Additionally, we test the hypothesis that parental socialization leads to a longer stay in public sector jobs while assuming that it serves as a buffer against turnover. Second, following public service motivation process theory, we expect that 'interest in politics' is influenced by parental socialization and that this concept, in turn, leads to a public sector career. A representative set of longitudinal data from the Swiss household panel (1999-2014) was used to analyse these hypotheses (n = 2,933, N = 37,328). The results indicate that parental socialization serves as a stronger predictor of public sector choice than an interest in politics. Furthermore, people with parents working in the public sector tend to stay longer in their public sector jobs. Points for practitioners For practitioners, the results of this study are relevant as they highlight the limited usefulness of addressing job applicants' interest in politics in the recruitment process. Human resources managers who want to ensure a public-service-motivated workforce are therefore advised to focus on human resources activities that stimulate public service motivation after job entry. We also advise close interaction between universities and public organizations so that students develop a realistic picture of the government as a future employer and do not experience a 'reality shock' after job entry.}, language = {en} } @article{CoviEydam2020, author = {Covi, Giovanni and Eydam, Ulrich}, title = {End of the sovereign-bank doom loop in the European Union?}, series = {Journal of evolutionary economics}, volume = {30}, journal = {Journal of evolutionary economics}, number = {1}, publisher = {Springer}, address = {Berlin ; Heidelberg ; New York}, issn = {0936-9937}, doi = {10.1007/s00191-018-0576-2}, pages = {5 -- 30}, year = {2020}, abstract = {In this paper we examine the relationship between the default risk of banks and sovereigns, i.e. the 'doom-loop'.

These questions are crucial to design policies that mitigate welfare losses of migration choices due to climate change. We study the direct and heterogeneous associations between weather extremes and migration in rural India. We combine ERAS reanalysis data with the India Human Development Survey household panel and conduct regression analyses by applying linear probability and multinomial logit models. This enables us to establish a causal relationship between temperature and precipitation anomalies and overall migration as well as migration by destination. We show that adverse weather shocks decrease rural-rural and international migration and push people into cities in different, presumably more prosperous states. A series of positive weather shocks, however, facilitates international migration and migration to cities within the same state. Further, our results indicate that in contrast to other migrants, climate migrants are likely to be from the lower end of the skill distribution and from households strongly dependent on agricultural production. We estimate that approximately 8\% of all rural-urban moves between 2005 and 2012 can be attributed to weather. This figure might increase as a consequence of climate change.

Therefore, the availability of reliable and robust co-transfection methods and defined selection criteria for their use in, e.g., expression of multimeric proteins or mixed RNA/DNA delivery is of utmost importance. Here, we investigated different co- and successive transfection approaches, with particular focus on in vitro transcribed messenger RNA (IVT-mRNA). Expression levels and patterns of two fluorescent protein reporters were determined, using different IVT-mRNA doses, carriers, and cell types. Quantitative parameters determining the efficiency of co-delivery were analyzed for IVT-mRNAs premixed before nanocarrier formation (integrated co-transfection) and when simultaneously transfecting cells with separately formed nanocarriers (parallel co-transfection), which resulted in a much higher level of expression heterogeneity for the two reporters. Successive delivery of mRNA revealed a lower transfection efficiency in the second transfection round. All these differences proved to be more pronounced for low mRNA doses. Concurrent delivery of siRNA with mRNA also indicated the highest co-transfection efficiency for integrated method. However, the maximum efficacy was shown for successive delivery, due to the kinetically different peak output for the two discretely operating entities. Our findings provide guidance for selection of the co-delivery method best suited to accommodate experimental requirements, highlighting in particular the nucleic acid dose-response dependence on co-delivery on the single-cell level.}, language = {en} } @article{NeufeldBobrovaDavletovetal.2020, author = {Neufeld, Maria and Bobrova, Anastacia and Davletov, Kairat and Stelemekas, Mindaugas and Stoppel, Relika and Ferreira-Borges, Carina and Breda, Joao and Rehm, J{\"u}rgen}, title = {Alcohol control policies in Former Soviet Union countries}, series = {Drug and alcohol review}, volume = {40}, journal = {Drug and alcohol review}, number = {3}, publisher = {Wiley}, address = {Hoboken}, issn = {0959-5236}, doi = {10.1111/dar.13204}, pages = {350 -- 367}, year = {2020}, abstract = {Issues The last Soviet anti-alcohol campaign of 1985 resulted in considerably reduced alcohol consumption and saved thousands of lives. But once the campaign's policies were abandoned and the Soviet alcohol monopoly broken up, a steep rise in mortality was observed in many of the newly formed successor countries, although some kept their monopolies. Almost 30 years after the campaign's end, the region faces diverse challenges in relation to alcohol. Approach The present narrative review sheds light on recent drinking trends and alcohol policy developments in the 15 Former Soviet Union (FSU) countries, highlighting the most important setbacks, achievements and best practices. Vignettes of alcohol control policies in Belarus, Estonia, Kazakhstan, Lithuania and Uzbekistan are presented to illustrate the recent developments.
Key Findings Over the past decade, drinking levels have declined in almost all FSU countries, paralleled by the introduction of various alcohol-control measures. The so-called three 'best buys' put forward by the World Health Organization to reduce alcohol-attributable burden (taxation and other measures to increase price, restrictions on alcohol availability and marketing) are relatively well implemented across the countries. Implications In recent years, evidence-based alcohol policies have been actively implemented as a response to the enormous alcohol-attributable burden in many of the countries, although there is big variance across and within different jurisdictions. Conclusion Strong declines in alcohol consumption were observed in the 15 FSU countries, which have introduced various alcohol control measures in recent years, resulting in a reduction of alcohol consumption in the World Health Organization European region overall.}, language = {en} } @article{LassGronau2020, author = {Lass, Sander and Gronau, Norbert}, title = {A factory operating system for extending existing factories to Industry 4.0}, series = {Computers in industry : an international, application oriented research journal}, volume = {115}, journal = {Computers in industry : an international, application oriented research journal}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0166-3615}, doi = {10.1016/j.compind.2019.103128}, pages = {8}, year = {2020}, abstract = {Cyber-physical systems (CPS) have shaped the discussion about Industry 4.0 (I4.0) for some time.

Moreover, this thesis contributes to the literature on methods for causal inference when the treatment variable is continuous rather than binary. For example, this is the case when individuals differ in their degree of exposure to a common treatment. The analysis of the effects of SUS focuses on the main current German program called "Gr{\"u}ndungszuschuss" (New Start-Up Subsidy, NSUS) after its reform in 2011. Average Effects on participants' labor market outcomes - as measured by employment and earnings - as well as subjective well-being are estimated mainly based on propensity score matching (PSM) techniques. PSM aims to achieve balance in terms of observed characteristics by matching participants with at least one comparable non-participant in terms of their probability to receive the treatment. This estimation strategy is valid as long as all relevant characteristics that explain selection patterns into treatment are observed and included in the estimation of the propensity score. To make our analysis as credible as possible, we control for a large vector of characteristics as observed through the combination of rich administrative data from the Federal Employment Agency as well as through survey data. Chapters two to four of this thesis puts special emphasis on aspects regarding (the evaluation of) SUS programs that have received no or only limited attention thus far. The first aspect relates to the interplay of institutional details of the program and its effectiveness. So far, relatively little is known about the importance of SUS program features such as the duration of support. Second, there is no experimental benchmark evaluation of SUS available and thus, the reliability of non-experimental estimation techniques such as PSM is of crucial importance as estimates are biased when relevant confounders are omitted from the analysis. Third, there may be potentially detrimental effects of transitioning into (relatively risky) self-employment on subjective well-being among subsidized founders out of unemployment. These were to remain undetected if the analysis would focus exclusively on labor market outcomes of participants. The results indicate positive long-term effects of SUS participation on employment and earnings among participants. These effects are substantially larger than what estimated before the reform, indicating room for improvement in program design via changes in institutional details. Moreover, non-experimental estimates of treatment effects are remarkably robust to hidden confounding. Regarding subjective well-being, this thesis finds a positive long-run impact on job satisfaction and a detrimental effect on satisfaction with social security. The latter appears to be driven by adverse effects on social insurance contributions. In chapter five, a novel automated covariate balancing technique for the estimation of causal effects in the context of continuous treatments is derived and assessed regarding its performance compared to other (automated) balancing techniques. Although binary research designs that only differentiate between participants and non-participants of some treatment remain the most-common case in empirical practice, many applications can be adapted to include continuous treatments as well. Often, this will allow for more meaningful estimates of causal effects in order to further improve the design of programs. In the context of SUS, one may further investigate the effects of the size of monetary support or its duration on participants' labor market outcomes. Both Monte-Carlo investigations and analysis of two well-known datasets suggests superior performance of the proposed Entropy Balancing for continuous treatments (EBCT) compared to other existing estimation strategies.}, language = {en} } @misc{BeneckeDeekenHammeretal.2020, author = {Benecke, Karin and Deeken, Johannes and Hammer, Carolin and Hinz, Carsten and L{\"o}ffler, Robert and Penning, Isabelle and Richter, Christin and Sch{\"a}fer, David and Scherer, Hubertus}, title = {\#Wirtschaft - Niedersachsen}, editor = {Kirchner, Vera}, publisher = {Buchner}, address = {Bamberg}, isbn = {978-3-661-82241-9}, pages = {320}, year = {2020}, language = {de} } @article{KruggelTiberiusFabro2020, author = {Kruggel, Alexander and Tiberius, Victor and Fabro, Manuela}, title = {Corporate Citizenship}, series = {Sustainability}, volume = {12}, journal = {Sustainability}, number = {13}, publisher = {MDPI}, address = {Basel}, issn = {2071-1050}, doi = {10.3390/su12135289}, pages = {19}, year = {2020}, abstract = {Corporate citizenship, which is firms' societal engagement beyond customer and shareholder interests, is a prominent topic in management practice and has led to extensive research.

It highlights innovative grassroots projects and shows how local activists can form alliances and discover their own power to solve problems.}, language = {en} } @book{Gronau2020, author = {Gronau, Norbert}, title = {Knowledge Modeling and Description Language 3.0}, publisher = {GITO}, address = {Berlin}, isbn = {978-3-95545-330-5}, pages = {75}, year = {2020}, language = {de} } @article{Heinemann2020, author = {Heinemann, Maik}, title = {Zyklische Ph{\"a}nomene in der {\"O}konomie -

If individuals anticipate that comparing their payoff with the (potentially higher) payoff of others will make them envious, they may want to actively avoid information about other people's payoffs. Given the opportunity to reduce another person's payoff, an individual's envy may trigger behavior that is detrimental to welfare. In this case, if individuals anticipate that they will react in a welfare-reducing way, they may also avoid information about other people's payoffs from the outset. We investigated these two hypotheses using three experiments. We found that 13\% of our potentially envious subjects avoided information when they did not have the opportunity to reduce another participant's payoff. Psychological scales do not explain this behavior. We also found that voluntarily uninformed subjects did neither deduct less of the payoff nor less frequently than subjects who could not avoid the information.}, language = {en} } @phdthesis{LeueBensch2020, author = {Leue-Bensch, Carina}, title = {Supporting the expression of entrepreneurial potential}, school = {Universit{\"a}t Potsdam}, pages = {XII, 127, XVIII}, year = {2020}, abstract = {The ability of a company to innovate and to launch innovation is a critical competitive edge to remain competitive in the 21st century. Large organizations therefore increasingly recognize employees as a significant factor and critical source of innovation. Several studies assert the fact that every employee has to offer certain skills and knowledge and can contribute to innovation. Hence, every employee has a certain 'entrepreneurial potential'. This potential can be expressed in the form of entrepreneurial behaviour and can occur in many ways, from monopersonal innovation championing to several small scale contributions, where several individuals team up for innovation. To support entrepreneurial behaviour of their employees, large organizations increasingly rely on Corporate Entrepreneurship. They set up organizational structures and venturing units, offer vehicles and tools to their employees to be more entrepreneurial. The evolvement of new tools and technologies thereby allow for new ways of employee involvement, also allowing for more radical innovation to be developed collaboratively. Yet, many of such offerings fail to achieve the desired outcome. While some employees immediately opt-in for innovation, others do not and their entrepreneurial potential remains untapped. This research explores how large organizations can better support their employees to express their entrepreneurial potential, thus moving from non-entrepreneurial behaviour or not wanting to be involved, to actually expressing entrepreneurial behaviour. The underlying research therefore is two-fold. While focusing on the individual level and the entrepreneurial behaviour of employees, this research also takes the organizational perspective into account in order to identify how non-entrepreneurial behaviour can be stimulated towards entrepreneurial behaviour. Using an empirical qualitative research design based on pragmatism and abduction, data is collected by means of qualitative interviews as well as a longitudinal use case setting. Grounded theory is then applied for analysis and sense making. The main outcome is a theoretical model of why employees are expressing or not expressing their entrepreneurial potential and how non-expression can potentially be triggered towards entrepreneurial behaviour. The results indicate that there is no one-size-fits all model of Corporate Entrepreneurship. This research therefore argues that organizations can achieve higher levels of entrepreneurial behaviour when addressing employees differently. By developing a theoretical model as well as suggestions of how this model can be applied in practice, this research contributes to theory and practice alike. This document closes suggesting future research areas around supporting employees to express their entrepreneurial potential.}, language = {en} } @techreport{SultanowKochCox2020, author = {Sultanow, Eldar and Koch, Christian and Cox, Sean}, title = {Collatz Sequences in the Light of Graph Theory}, edition = {4th version}, doi = {10.25932/publishup-44325}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-443254}, pages = {31}, year = {2020}, abstract = {It is well known that the inverted Collatz sequence can be represented as a graph or a tree.
