The model encompasses both the case of a common owner holding shares of rival firms as well as the case of cross ownership among rivals. We find that by softening competition, NCMS weaken the sustainability of collusion under a greater variety of situations than was indicated by earlier literature. Such effects exist, in particular, in the presence of an effective competition authority.

Political-economy related aspects are considered in the government's objective function. Lobbying power of firms or fiscal considerations by the government lead to time inconsistency: The government will deviate from a previously announced carbon tax which creates stranded assets. 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. Which of the two outcomes (all or nothing) prevails depends on the lobbying power of owners of fixed factors (land and fossil resources) but not on fiscal revenue considerations or on the lobbying power of renewable or fossil energy firms.

We study distributional implications of seasonal weather and climate on within-country inequality in rural India. Utilizing a first difference approach, we find that the poor are more sensitive to weather variations than the non-poor. The poor respond more strongly to (seasonal) temperature changes: negatively in the (warm) spring season, more positively in the (cold) rabi season. Less precipitation is harmful to the poor in the monsoon kharif season and beneficial in the winter and spring seasons. We show that adverse weather aggravates inequality by reducing consumption of the poor farming households. Future global warming predicted under RCP8.5 is likely to exacerbate these effects, reducing consumption of poor farming households by one third until the year 2100. We also find inequality in consumption across seasons with higher consumption during the harvest and lower consumption during the sowing seasons.

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.

Employing annual panel models, long-difference regressions and cross-sectional regressions, we identify effects on productivity levels and productivity growth. We do not find evidence for permanent growth rate impacts but we find robust evidence that temperature affects productivity levels considerably. An increase in global mean surface temperature by about 3.5°C until the end of the century would reduce global output by 7–14% in 2100, with even higher damages in tropical and poor regions. Updating the DICE damage function with our estimates suggests that the social cost of carbon from temperature-induced productivity losses is on the order of 73–142$/tCO2 in 2020, rising to 92–181$/tCO2 in 2030. These numbers exclude non-market damages and damages from extreme weather events or sea-level rise.

Der angedeutete Paradigmenwechsel der deutschen Klimapolitik öffnet damit die Tür, die europäische und internationale Kooperation zu stärken.

Auch dort sollten sich die Verhandlungen statt auf nationale Mengenziele auf CO2-Preise konzentrieren. Die erforderliche Kooperation wird möglich, wenn die Regierungen Transferzahlungen strategisch und reziprok nutzen.

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.

To address unobserved heterogeneity and omitted variables, we present long difference/fixed effects estimates and instrumental variables estimates, using historical population and soil quality as instruments. Using our preferred estimates, we find that the concentration increases with density for NO2 with an elasticity of 0.25 and particulate matter with elasticity of 0.08. The O-3 concentration decreases with density with an elasticity of -0.14. The AQI increases with density, with an elasticity of 0.11-0.13. We also present a variety of robustness tests.

We investigate how sharecropping tenure is related to climate risk and how it interacts with fertilizer use and livestock ownership that both influence production risk. We first develop a stylized theoretical model to illustrate the role of climate for land tenure and production. Our empirical analysis is based on more than 9000 households with considerable heterogeneity in climate conditions across several African countries. We find that farmers in areas with low precipitation are more likely to be sharecroppers. We further find evidence for risk management interaction effects as sharecropping farmers are less likely to own livestock and more likely to use fertilizer. In economies where formal kinds of insurance are unavailable, sharecropping thus functions as a form of insurance and reduces the need for potentially costly risk management strategies.

T2 - Proceedings of the 28th European Conference on Information Systems (ECIS): ECIS 2020 Panels N2 - Data sharing requires researchers to publish their (primary) data and any supporting research materials. With increased attention on reproducibility and more transparent research requiring sharing of data, the issues surrounding data sharing are moving beyond whether data sharing is beneficial, to what kind of research data should be shared and how. However, despite its benefits, data sharing still is not common practice in Information Systems (IS) research. The panel seeks to discuss the controversies related to data sharing in research, specifically focusing on the IS discipline. It remains unclear how the positive effects of data sharing that are often framed as extending beyond the individual researcher (e.g., openness for innovation) can be utilized while reducing the downsides often associated with negative consequences for the individual researcher (e.g., losing a competitive advantage). To foster data sharing practices in IS, the panel will address this dilemma by drawing on the panelists’ expertise.

Design/methodology/approach Journal (co-)citation analysis, author (co-)citation analysis, institution citation and co-operation analysis, keyword co-occurrence analysis, document (co-)citation analysis and burst detection analysis were conducted based on a bibliometric data set relating to sharing economy publications. Findings Sharing economy research is multi- and interdisciplinary. Journals focused upon products liability, organizing framework, profile characteristics, diverse economies, consumption system and everyday life themes. Authors focused upon profile characteristics, sharing economy organization, social connections, first principle and diverse economy themes. No institution dominated the research field. Keyword co-occurrence analysis identified organizing framework, tourism industry, consumer behavior, food waste, generous exchange and quality cue as research themes. Document co-citation analysis found research themes relating to the tourism industry, exploring public acceptability, agri-food system, commercial orientation, products liability and social connection. Most cited authors, institutions and documents are reported. Research limitations/implications The study did not exclusively focus on publications in top-tier journals. Future studies could run analyses relating to top-tier journals alone, and then run analyses relating to less renowned journals alone. To address the potential fuzzy results concern, reviews could focus on business and/or management research alone. Longitudinal reviews conducted over several points in time are warranted. Future reviews could combine qualitative and quantitative approaches. Originality/value We contribute by analyzing information relating to the population of all sharing economy articles.

This systematic literature review aims to structure the field, identify current research themes, and provide a better understanding of prior research outcomes. Our results show that dark triad research addresses entrepreneurial activity, opportunity recognition, entrepreneurial orientation, entrepreneurial leadership, the and entrepreneurial motives. Among the dark triad traits, narcissism is stressed most in research so far. It relates to firm performance, risk, and leadership behavior, whereas Machiavellianism and psychopathy relate to opportunity recognition and exploitation.

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.

We use a panel with daily data on European banks and sovereigns ranging from 2012 to 2016 in order to test the effects of the Bank Recovery and Resolution Directive on the two-way feedback process. We find that there was a pronounced feedback loop between banks and sovereigns from 2012 to 2014. However, after the implementation of the European Banking Union, in 2015/2016, the magnitude of the doom-loop decreased and the spillovers became not statistically significant. Furthermore, our results suggest that the implementation of the new resolution framework is a suitable candidate to explain this finding.

BT - Evidence from rural India JF - World development N2 - In this paper, we move from the large strand of research that looks at evidence of climate migration to the questions: who are the climate migrants? and where do they go? 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. Thus, a key policy recommendation is to take steps to facilitate integration of less educated migrants into the urban labor market.

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.

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.

N2 - Does political repression work and if so, under what conditions? Many contributions to the empirical study of non-democratic rule assume it does. As a consequence, strong convictions on political repression abound, but empirical investigations into the matter remain rare. This introduction sets the agenda for the chapters to come and outlines the answers given to the three motivating questions of this volume. First, what variants of political repression are there, and how do they interact? Second, what impact does the interaction of different forms of political repression have on the problem of authoritarian control? Finally, what difference does the complementary use of violence and restrictions make for the problem of authoritarian power-sharing?

Platform owners provide platform boundary resources that allow for application development. For developers, platform integration, understood as the employment of platform resources, helps to realize application functionality effectively. Simultaneously, it requires integration effort and increases dependencies. Developers are interested to know whether integration contributes to success in hypercompetitive platform settings. While aspects of platform participation have been studied, research on a comprehensive notion of integration and related implications are missing. By proposing a platform integration model, this study supports a better understanding of integration. Concerning dynamics related to integration, effects were tested using information from over 82,000 Apple AppStore applications. Regression model analysis reveals that application success and customer satisfaction is positively influenced by platform integration. To achieve superior results, developers should address multiple aspects of integration, such as devices, data, the operating system, the marketplace as well as other applications, and provide updates. Finally, the study highlights the importance for all platform participants and their possibilities to employ integration as a strategic instrument.

Similarly, it is acknowledged that in order to prove the Collatz conjecture, one must demonstrate that this tree covers all odd natural numbers. A structured reachability analysis is hitherto unavailable. This paper investigates the problem from a graph theory perspective. We define a tree that consists of nodes labeled with Collatz sequence numbers. This tree will be transformed into a sub-tree that only contains odd labeled nodes. Furthermore, we derive and prove several formulas that can be used to traverse the graph. The analysis covers the Collatz problem both in it’s original form 3x + 1 as well as in the generalized variant kx + 1. Finally, we transform the Collatz graph into a binary tree, following the approach of Kleinnijenhuis, which could form the basis for a comprehensive proof of the conjecture.

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 “Gründungszuschuss” (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. N2 - Diese Dissertation bietet neue Erkenntnisse über die Auswirkungen von Gründungsförderung (GF) für Arbeitslose. Diese Art der Förderung stellt einen besonderen Ansatz zur Reintegration von Arbeitslosen in den Arbeitsmarkt über den Weg in die Selbstständigkeit dar. Darüber hinaus leistet diese Arbeit einen Beitrag zur Literatur über Methoden der kausalen Inferenz und entwickelt einen neuen Schätzer. Dieser kann angewendet werden, wenn Maßnahmen mit Hilfe einer kontinuierlich verteilten statt einer binären Variable abgebildet werden. Dies ist zum Beispiel der Fall, wenn sich Individuen im Grad ihrer Betroffenheit von einer Maßnahme unterscheiden. Die Analyse von Effekten der GF konzentriert sich auf das aktuell größte deutsche Gründungsförderungsprogramm für Arbeitslose namens "Gründungszuschuss" nach dessen Reform im Jahr 2011. Dabei werden die Auswirkungen der GF auf die Arbeitsmarktergebnisse bezüglich Beschäftigung und Einkommen sowie das subjektive Wohlbefinden der Teilnehmer analysiert. Zur Schätzung dieser Effekte werden hauptsächlich Propensity Score Matching (PSM) Techniken verwendet, die es zum Ziel haben die Verteilung von beobachteten Charakteristika zwischen Teilnehmern und Nicht-Teilnehmer möglichst perfekt anzugleichen. Dies wird erreicht, indem jedem Teilnehmer mindestens ein Nicht-Teilnehmer mit möglichst ähnlicher Teilnahmewahrscheinlichkeit zugewiesen wird. Dieser Schätzansatz ist valide unter der Annahme, dass alle relevanten Charakteristika, die die Selektion in die Maßnahme erklären, auch tatsächlich beobachtet und in der Schätzung der Teilnahmewahrscheinlichkeit berücksichtigt werden. Um unsere Analyse möglichst plausibel zugestalten, kontrollieren wir daher für eine große Anzahl an Charakteristika. Diese beobachten wir durch die Kombination aus den sehr informativen Prozessdaten der Bundesagentur für Arbeit sowie durch zusätzliche Befragungsdaten, die durch computergestützte Telefoninterviews erhoben wurden. Kapitel zwei bis vier der vorliegende Arbeit legen bei der Analyse einen besonderen Schwerpunkt auf Aspekte von Gründungsförderungsprogrammen, die bisher keine oder nur begrenzte Aufmerksamkeit erhalten haben. Zu diesen Fragen gehören zum einen das Zusammenspiel der institutionellen Ausgestaltung des Programms wie die Länge der Förderung und seiner Wirksamkeit. Zum anderen betrifft dies die Validität der Schätzergebnisse, da bisher keine experimentelle Evidenz zu den Effekten der GF verfügbar ist. Nicht-experimentelle Verfahren wie PSM liefern verzerrte Schätzungen kausaler Effekte, wenn relevante Charakteristika in der Analyse nicht berücksichtigt werden. Daher gilt es das Risiko einer Verzerrung eingehend zu untersuchen. Darüber hinaus könnte es durch die relativ risikohafte Natur der Selbständigkeit zu negativen Effekten auf das subjektive Wohlbefinden der subventionierten Gründer aus Arbeitslosigkeit kommen. Diese blieben unentdeckt, wenn sich die Analyse nur auf die Arbeitsmarktergebnisse der Teilnehmer beschränkt. In Kapitel fünf wird ein neuartiges automatisiertes Verfahren zur Angleichung von beobachteten Charakteristika für die Schätzung kausaler Effekte im Kontext kontinuierlicher Maßnahmenveriablen entwickelt und hinsichtlich seiner Leistung im Vergleich zu anderen gängigen Verfahren bewertet. Obwohl binäre Forschungsdesigns, die nur zwischen Teilnehmern und Nicht-Teilnehmern unterschieden, in der empirischen Praxis nach wie vor am häufigsten zu beobachten sind, könnten viele Interventionen ebenfalls aus dem Blickwinkel einer kontinuierliche Maßnahme analysiert werden. Im Kontext der GF könnten zum Beispiel Programmteilnehmer mit unterschiedlicher Höhe oder Dauer der Förderung miteinander verglichen werden. Die Analyse dieser Aspekte bietet die Möglichkeit, noch politikrelevantere Schätzungen kausaler Effekte zu erlangen. Kapitel zwei legt einen Fokus auf die Reform des Gründungszuschusses und zielt darauf ab, unser Verständnis darüber zu verbessern, wie sich Veränderungen der institutionellen Faktoren auf die Effektivität des Programms auswirken können. Durch die Reform wurden die Zugangskriterien verschärft, die Finanzielle Unterstützung reduziert und der Ermessensspielraum der Arbeitsvermittler der Agenturen für Arbeit hinsichtlich der Ablehnung von Bewerbern erweitert. Aus theoretischer Sicht ist es unklar, wie sich diese Änderungen auf das Programm insgesamt auswirken werden, da möglicherweise gegenläufige Kräfte im Spiel sind. Beispielsweise könnte die Reduzierung der Finanziellen Unterstützung zu einer Verringerung von Fehlanreizen ("moral hazard") unter den Teilnehmern führen und dadurch die Wirksamkeit des Programms erhöhen. Gleichzeitig könnte ein niedrigeres Niveau der monetären Transfers nicht ausreichend sein, um potenzielle Kapitalbeschränkungen der Gründungen abzumildern, wodurch die Wirksamkeit des Programms verringert würde. Die Ergebnisse dieses Kapitels zeigen, dass die institutionellen Veränderungen des Programms mit bemerkenswerten Unterschieden in der Komposition der Teilnehmergruppe vor bzw. nach der Reform verbunden sind. Außerdem weisen Teilnehmergruppen signifikante Unterschiede bezüglich ihrer Beschäftigung sowie ihrer Arbeitsverdienste auf. Darüber hinaus zeigen die Ergebnisse große positive Effekte des Programms auf die kurzfristigen Arbeitsmarktresultate der Teilnehmer. Diese Effekte sind tatsächlich wesentlich größer als die für das Programm vor der Reform geschätzten Effekte, obwohl die Reform die Finanzielle Unterstützung der Teilnehmer reduziert hat. Diese Ergebnisse stehen unter dem Vorbehalt, dass Verzerrungen aufgrund unterschiedlicher makroökonomischen Rahmenbedingungen über die Zeit möglich sind. Allerdings scheinen die Ergebnisse darauf hinzudeuten, dass die Reform das Programm für die Teilnehmer tatsächlich insgesamt effektiver gemacht hat. Somit liefern wir wichtige erste Anhaltspunkte dafür, dass die politischen Entscheidungsträger durch eine Änderung des institutionellen Designs die Wirksamkeit von Gründungsförderungsprogrammen weiter verbessern können. Kapitel drei schätzt die langfristigen Auswirkungen des Gründungszuschusses nach dessen Reform und konzentriert sich dabei auf Fragen der Validität der nichtexperimentellen Schätzungen. Während Belege für das Programm vor der Reform darauf hindeuten, dass die Schätzungen robust gegenüber der Auslassung normalerweise nicht beobachteter Persönlichkeitsmerkmale sind (Caliendo et al., 2016), ist unklar, ob diese Befunde auch nach der Reform noch zutreffen. Dies liegt daran, dass die Reform eine weitere Ebene der Selektion durch die Arbeitsvermittler einführte, indem das Programm von einer Pflicht- zur Ermessensleistung umgewandelt wurde. Daher untersucht dieses Kapitel mit großer Sorgfalt die Robustheit der Schätzungen für das Programm nach der Reform im Hinblick auf die Art und Weise, wie Matching Schätzer implementiert werden, sowie im Hinblick auf die Sensitivität bezüglich ausgelassener unbeobachteter Charakteristika. Des Weiteren geht dieses Kapitel über den Standardansatz des Propensity Score Matchings hinaus und liefert erste Schätzungen von Effekten auf Basis einer Instrumentalvariablen (IV), indem die durch die Reform induzierten regionalen Unterschiede in der Bewilligungsrate von Bewerbungen für die Gründungsförderung ausgenutzt werden. Die Ergebnisse dieses Kapitels liefern weitere Evidenz für die günstigen Effekte der GF auf die Arbeitsmarktergebnisse der Teilnehmer. Selbst auf lange Sicht sind die geschätzten Effekte für das Programm nach der Reform bezüglich Beschäftigung und Einkommen wesentlich größer als die des Programms vor der Reform (siehe Caliendo et al., 2016). Unsere Sensitivitätsanalysen der Matching-Schätzwerte zeigen, dass diese sehr robust gegenüber alternativen Methoden zur Implementierung des Matchings sowie der Auslassung relevanter Charakteristika sind. Interessanterweise zeigen die Ergebnisse auch, dass Persönlichkeitsmerkmale, welche in vielen Anwendungen nicht zu beobachten sind, eine relativ große - und im Vergleich zum unreformierten Programm eine weitaus größere - Rolle für die Selektion in das Programm spielen. Allerdings liefern Schätzungen auf Basis einer erweiterten Spezifikation, die diese Variablen enthält, fast identische Ergebnisse im Vergleich zu unserer Basisspezifikation. In ähnlicher Weise untermauern die IV-Schätzungen unsere wichtigsten Schlussfolgerungen, indem sie große und anhaltende Auswirkungen auf Beschäftigung und Einkommen aufzeigen. Unsere Ergebnisse zeigen daher, dass nicht-experimentelle Schätzstrategien robuste Evidenz bezüglich der Effekte des Gründingszuschusses liefern. Kapitel vier nutzt zusätzlich Messungen des subjektivenWohlbefindens als Ergebnisvariablen für die Evaluation des Gründungszuschusses statt rein objektiver Variablen wie Beschäftigung oder Einkommen. Die Hauptmotivation dafür ist, dass die Subventionierung des Übergangs in die Selbständigkeit aufgrund ihres risikoreichen Charakters unbeabsichtigte negative Auswirkungen auf das subjektiveWohlbefinden der Teilnehmer haben könnte, selbst wenn sie die Arbeitsmarktergebnisse der Teilnehmer positiv beeinflusst. Zur Messung des subjektiven Wohlbefindens werden Informationen über die Lebenszufriedenheit sowie über die Zufriedenheit mit der Gesundheit, dem Einkommen, der Arbeit und der sozialen Sicherheit des Einzelnen verwendet. Um die Effekte zu schätzen werden wiederum Propensity-Score-Matching Techniken eingesetzt. Unsere Hauptergebnisse zeigen, dass GF kurzfristig einen positiven Einfluss auf die Lebenszufriedenheit der Teilnehmer hat. Dieser Effekt ist jedoch langfristig nicht mehr statistisch signifikant. Darüber hinaus finden wir zwar langfristig positive Auswirkungen der GF auf die Jobzufriedenheit, aber auch große negative Effekte auf die Zufriedenheit mit der sozialen Sicherheit. Ergänzende Ergebnisse deuten darauf hin, dass letztere durch eine signifikant verringerte Teilnahme an der gesetzlichen Arbeitslosen- bzw. einer Rentenversicherung bedingt sein könnten. Dadurch sind Maßnahmenteilnehmer einer erhöhten Gefahr durch eine zukünftige Rezession bzw. Altersarmut ausgesetzt. Darüber hinaus finden wir eine starke Heterogenität in den Effekten auf Subgruppen definiert durch Geschlecht, Alter und Ausbildung. Im Vergleich zu den vorherigen Kapiteln liefern diese Ergebnisse eine etwas weniger optimistische Einschätzung der Auswirkungen der GF auf die Teilnehmer. In Anlehnung an die PSM Techniken wird in Kapitel fünf ein neuartiges automatisiertes Gewichtungsverfahren entwickelt, das die Schätzung kausaler Effekte mittels semi- oder nichtparametrischer Methoden erleichtert, wenn die Maßnahmenvariable kontinuierlich verteilt ist. Mögliche Beispiele hierfür sind die Dauer von Trainingmaßnahmen oder wie Höhe von Subventionen für Firmen. Das entwickelte Verfahren namens Entropy Balancing für kontinuierliche Treatments (EBCT) beseitigt die Pearson-Korrelation zwischen den Charakteristika der Teilnehmer und der Maßnahmenvariablen. Durch die Einbeziehung von Polynomen kontinuierlicher Variablen sowie von Interaktionstermen kann eine Angleichung der Charakteristika nicht nur in Bezug auf die Mittelwerte, sondern auch in Bezug auf höhere Momente sowie Kreuzmomente erreicht werden. Die Lösung eines global konvexen Optimierungsproblems garantiert, dass die Charakteristika in der resultierenden synthetischen Stichprobe perfekt angeglichen wurden. Dieses Ergebnis gilt auch dann noch, wenn die Charakteristika eine hohe Vorhersagekraft für den Grad der Exposition haben und andere Methoden keine akzeptable Anpassung liefern. Darüber hinaus ermöglicht die Art des Optimierungsproblems eine effiziente Software-Implementierung und ist daher rechnerisch weniger aufwendig als andere Schätzer. Simulationsevidenz zeigt günstige Eigenschaften von Schätzungen auf der Grundlage der EBCT Gewichte bezüglich Verzerrung und Varianz auf. Insgesamt zeigen unsere Analysen relativ große positive Effekte des Gründungszuschusses auf den Arbeitsmarkterfolg der Teilnehmer, sowohl im Vergleich mit anderen Arbeitsmarktprogrammen als auch mit dem Programm vor dessen Reform. Sogar in der langen Frist sind die Effekte deutlich größer als die Schätzungen der Effekte vor der Reform, obwohl die Finanzielle Unterstützung der Teilnehmer reduziert wurde. Dies impliziert eine positive Wirkung der Reform: Die Effekte sind gestiegen und die Kosten pro Teilnehmer sind gesunken. Allerdings erlaubt der mikroökonometrische Ansatz dieser Dissertation keine Analyse der Effekte auf die Gesamtwohlfahrt. So ist durchaus möglich, dass der Netto-Effekt der Reform negativ ist, da durch die verringerten Teilnehmerzahlen potentiell profitable Gründungen vielleicht nie realisiert wurden. Dies bedarf weiterer Untersuchungen. Auf methodischer Ebene zeigen unsere umfangreichen Sensitivitätsanalysen, dass die nichtexperimentelle Schätzung der Effekte höchst robuste Ergebnisse liefert, obwohl die Reform eine zusätzliche Ebene der Selektion durch die Arbeitsvermittler eingeführt hat. Da viele Programme eine relativ ähnliche Struktur wie der Gründungszuschuss aufweisen, können unsere Ergebnisse anderen Studien womöglich zusätzliche Glaubwürdigkeit verleihen. Darüber hinaus deuten die Ergebnisse auf einen potentiell nicht unerheblichen Spielraum zur Verbesserung der Effektivität der Programme durch Veränderungen der institutionellen Details hin. Für konkrete Handlungsempfehlungen bedarf es allerdings weiterer Untersuchungen. Unsere Analyse der Effekte auf das subjektive Wohlbefinden der Teilnehmer zeigt den zusätzlichen Nutzen solcher Ergebnisvariablen, um unbeabsichtigte negative Effekte der Programme aufzudecken. Um die nachteiligen Effekte auf die Zufriedenheit mit der sozialen Absicherung abzumildern, würde es sich anbieten die Teilnehmer stärker in das soziale Sicherungsnetz einzubinden. Das vorgestellte EBCT Verfahren erlaubt die weitergehende Untersuchung der Auswirkungen der GF sowie weiterer kontinuierlicher Maßnahmen. Durch seine guten Eigenschaften erlaubt das EBCT die Nutzung von semi- oder nicht-parametrischen Methoden zur Schätzung kausaler Effekte, wo bisher nur - vielleicht zu restriktive - parametrische Methoden zur Verfügung standen.

Beide Länder sind in diesem Sektor Hauptakteure und Hauptpartner. Die Europäische Weltraumorganisation, die sich auf diese zivile und militärische Doppelindustrie stützt, hat Europa auf der Weltbühne einen wichtigen Platz eingeräumt. Um die Jahrhundertwende hat das Schaffen von Clustern dazu beigetragen, die Innovation in einem Sektor zu unterstützen, der wegen neuer internationaler Akteure in Frage gestellt wird. Diese Cluster haben sich auf der wirtschaftlichen Ebene des Sektors etabliert: in diesen Organisationen koexistieren private und öffentliche Akteure, die von der Forschung bis zur Implementierung der entwickelten Technologien zusammenarbeiten. Zu der Vielzahl der Maßnahmen zur Innovationsförderung in Frankreich und Deutschland werden nun die von der Europäischen Kommission festgelegten europäischen Ziele hinzugefügt. Wettbewerbscluster werden nicht mehr als privilegierte Instrumente der europäischen Weltraumpolitik identifiziert wie in den deutsch-französischen Kooperationsprojekten der letzten Jahre. Die lokalen Kapazitäten dieser Organisationen sind nicht den heutigen europäischen wirtschaftlichen Probleme angepasst und erlauben es nicht, sich effektiv in die moderne Raumfahrtindustrie zu integrieren. N2 - Since the fifties and the early hours of the space age, France and Germany have contributed to the emergence of a European space industry in which they both are the main actors and the main partners. The European Space Agency, relying on this dual industry, both civilian and military, enabled Europe to reach a world competitive position. The creation of competitiveness clusters at the turn of the 21st century helped to support innovation in a sector challenged by the entry of new international players. These clusters have established themselves in this specific sector by creating organizations where private and public actors coexist and collaborate, ranging from research to the implementation of the technologies developed. The multiplicity of innovation support policies in France and Germany is now complemented by the European objectives defined by the European Commission. The competitiveness clusters are not identified as privileged instruments neither by the European space policy nor by the Franco-German cooperation projects of the last years. The limited action range of these organizations is not adapted to the European economic issues that prevail today and does not allow them to integrate effectively into the modern space industry. N2 - Depuis les débuts de l’ère spatiale à la seconde moitié du XXème siècle, la France et l’Allemagne ont contribué à l’émergence d’une industrie spatiale européenne dont ils sont les deux principaux acteurs et les principaux partenaires. L’agence spatiale européenne, en s’appuyant sur cette industrie duale, à la fois civile et militaire, a donné une place importante à l’Europe sur la scène mondiale. La création de pôles de compétitivité au tournant du XXIème siècle a contribué à soutenir l’innovation dans un secteur bousculé par l’arrivée de nouveaux acteurs internationaux. Ces pôles se sont imposés dans le paysage économique du secteur en créant des organisations où cohabitent et collaborent des acteurs privés et publics allant de la recherche à la mise en oeuvre des technologies développées. A la multiplicité des politiques de soutien à l’innovation en France et en Allemagne s’ajoutent désormais les objectifs européens définis par la Commission Européenne. Les pôles de compétitivité ne sont pas identifiés comme des instruments privilégiés de la politique spatiale européenne pas plus que dans les projets de coopération franco-allemands des dernières années. La capacité d’action locale de ces organisations n’est pas adaptée aux enjeux économiques à dimension européenne qui prévalent aujourd’hui et ne leur permet pas de s’intégrer efficacement dans l’industrie spatiale moderne.

Es kann zum einen eine bessere Patientenbindung geschaffen werden, die Qualität kann gemessen, verglichen und optimiert werden und es kann ein Mitarbeiterleitfaden im Sinne einer „Corporate Identity“ erstellt werden, welcher konkrete Managementimplikationen im Sinne von Handlungsimplikationen enthält. Der Leitgedanke des Qualitätsmanagements ist die Patientenorientierung im Sinne der Patientenzentrierten Medizin. Hierbei sollen nicht nur Wünsche und Bedürfnisse des Patienten erfüllt werden, sondern vorallem auch die Zufriedenheit gemessen und geplant werden. Gleichzeit muss man in diesem Zusammenhang die Behandlung der Patienten als Dienstleistung verstehen und die größtmögliche Zufriedenheit des Patienten als primäres Ziel setzen. Dies führt zu einer Kundenbindung dadurch, dass Patienten sowohl eine gleichbleibende Qualität erwarten können als auch und auch weiche Faktoren ihren Wünschen entsprechen werden. Corporate Identity mit dem Ziel als Unternehmen einheitlich für die Werte und damit die Qualität zu stehen.. Dies ermöglicht, das Wohlbefinden in der Vorstellung der Patienten beginnen zu lassen und dadurch Vertrauen zu schaffen. Alle drei Säulen haben nicht nur die Patientenzufriedenheit zum Ziel, sondern in gleichem Maße auch die Positionierung einer Institution auf dem Gesundheitsmarkt und damit die Verbesserung der Kosten-Nutzen-Rechnung durch ein positives Outcome. Damit fördern Zufriedenheitsanalysen nicht nur die ökonomische Position einer Abteilung, sondern behalten gleichermaßen die ethischen Aspekte einer Arzt-Patienten-Beziehung im Blick.

In communities where jobs and industry are scarce, many feel the government is incapable of understanding their needs or addressing their problems. The resulting frustration has fueled the success of destabilizing demagogues. To reverse this pattern and restore responsible government, we need to reinvigorate democracy at the local level. But what does that mean? Drawing on examples of successful community building in cities large and small, from a shrinking village in rural Austria to a neglected section of San Diego, Reconstructing Democracy makes a powerful case for re-engaging citizens. It highlights innovative grassroots projects and shows how local activists can form alliances and discover their own power to solve problems.

T2 - CEPA Discussion Papers N2 - Envy is an unpleasant emotion. 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.

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. N2 - Die Fähigkeit eines Unternehmens Innovationen zu generieren und am Markt einzuführen, ist eine entscheidende Wettbewerbsfähigkeit, um im 21sten Jahrhundert konkurrenzfähig zu bleiben. Große Unternehmen erkennen dabei zunehmend den Wert ihrer Mitarbeiter als wesentliche Quelle für Innovation. Zahlreiche Studien belegen, daß alle Mitarbeiter das Potential haben, ihre Fähigkeiten und Wissen in die Entwicklung von Innovationen einzubringen. Alle Mitarbeiter verfügen dementsprechend über ein innovatives Potential. Dieses Potential kann durch innovatives Verhalten in unterschiedlicher Art und Weise ausgedrückt werden. Dazu gehört ‚innovation championing‘, in dem einzelne Mitarbeiter Innovationen vorantreiben, genauso wie kleine Beiträge verschiedener Mitarbeiter zur gemeinsamen Erarbeitung von Innovationen. Um das innovative Verhalten ihrer Mitarbeiter zu unterstützen, beruhen große Unternehmen zunehmend auf Corporate Entrepreneurship. Sie etablieren Organisationstrukturen und Venturing Units und stellen ihren Mitarbeitern Tools und Methoden bereit, um innovatives Verhalten hervorzurufen. Die Entstehung neuer Tools und Technologien ermöglicht dabei neue Wege zur Einbindung von Mitarbeitern in den Innovationsprozess und bietet zunehmend die Möglichkeit zur kollaborativen Entwicklung radikaler Innovationen. Nichtsdestotrotz erzielen vieler dieser Angebote nicht das gewünschte Ergebnis. Während einige Mitarbeiter sich intensiv am Innovationsgeschehen beteiligen, bleiben andere skeptisch und ihr Innovationspotential bleibt unausgeschöpft. Diese Arbeit untersucht, wie große Unternehmen ihre Mitarbeiter besser dabei unterstützen können, ihr Innovationspotential zum Ausdruck zu bringen und sie von nicht-innovativem Verhalten hin zu innovativem Verhalten zu bewegen. Das dieser Arbeit zugrundeliegende Vorgehen ist dabei zweigleisig. Während der Fokus auf dem Individuum und dem innovativen Verhalten von Mitarbeitern liegt, wird auch die organisatorische Ebene betrachtet, um mögliche Methoden zur Stimulation innovativen Verhaltens zu identifizieren. Anhand eines empirischen Forschungsdesigns, das auf Pragmatismus und Abduktion beruht, werden Daten anhand qualitativer Interviews sowie mittels einer longitudinalen Fallstudie erhoben. Die Auswertung und Analyse der Daten erfolgt anhand der Grounded Theory. Das Resultat dieser Studie ist ein theoretisches Model ‚Supporting the Expression of Entrepreneurial Potential‘ zur Unterstützung innovativen Verhaltens von Mitarbeitern. Die Ergebnisse implizieren, daß Unternehmen unterschiedliche Typen von Mitarbeitern differenziert adressieren sollten, um deren Innovationsverhalten zu unterstützen. Durch die Entwicklung eines theoretischen Models sowie der Ableitung konkreter Handlungsempfehlung für Unternehmen, leistet diese Arbeit einen Beitrag für Forschung und Praxis und leitet schließlich Empfehlungen für künftige Forschung zur Unterstützung innovativen Verhaltens von Mitarbeitern ab.
