To moderate the consequences of unemployment industrialized countries spend substantial shares of their GDP on labor market policies, while in recent years there has been a shift from passive measures, such as transfer payments, towards more activating elements which aim to promote the reintegration into the labor market. Although, there exists a wide range of evidence about the effects of traditional active labor market policies (ALMP) on participants' subsequent labor market outcomes, a deeper understanding of the impact of these programs on the job search behavior and the interplay with long-term labor market outcomes is necessary. This allows policy makers to improve the design of labor market policies and the allocation of unemployed workers into specific programs. Moreover, previous studies have shown that many traditional ALMP programs, like public employment or training schemes, do not achieve the desired results. This underlines the importance of understanding the effect mechanisms, but also the need to develop innovative programs that are more effective. This thesis extends the existing literature with respect to several dimensions. First, it analyzes the impact of job seekers' beliefs about upcoming ALMPs programs on the effectiveness of realized treatments later during the unemployment spell. This provides important insights with respect to the job search process and relates potential anticipation effects (on the job seekers behavior before entering a program) to the vast literature evaluating the impact of participating in an ALMP program on subsequent outcomes. The empirical results show that training programs are more effective if the participants expect participation ex ante, while expected treatment effects are unrelated to the actual labor market outcomes of participants. A subsequent analysis of the effect mechanisms shows that job seekers who expect to participate also receive more information by their caseworker and show a higher willingness to adjust their search behavior in association with an upcoming ALMP program. The findings suggest that the effectiveness of training programs can be improved by providing more detailed information about the possibility of a future treatment early during the unemployment spell. Second, the thesis investigates the effects of a relatively new class of programs that aim to improve the geographical mobility of unemployed workers with respect to the job search behavior, the subsequent job finding prospects and the returns to labor market mobility. To estimate the causal impact of these programs, it is exploited that local employment agencies have a degree of autonomy when deciding about the regional-specific policy mix. The findings show that the policy style of the employment agency indeed affects the job search behavior of unemployed workers. Job seekers who are assigned to agencies with higher preferences for mobility programs increase their search radius without affecting the total number of job applications. This shift of the search effort to distant regions leads to a higher probability to find a regular job and higher wages. Moreover, it is shown that participants in one of the subsidy programs who move to geographically distant region a earn significantly higher wages, end up in more stable jobs and face a higher long-run employment probability compared to non-participants. Third, the thesis offers an empirical assessment of the unconfoundedness assumption with respect to the relevance of variables that are usually unobserved in studies evaluating ALMP programs. A unique dataset that combines administrative records and survey data allows us to observe detailed information on typical covariates, as well as usually unobserved variables including personality traits, attitudes, expectations, intergenerational information, as well as indicators about social networks and labor market flexibility. The findings show that, although our set of usually unobserved variables indeed has a significant effect on the selection into ALMP programs, the overall impact when estimating treatment effects is rather small. Finally, the thesis also examines the importance of gender differences in reservation wages that allows assessing the importance of special ALMP programs targeting women. In particular, when including reservation wages in a wage decomposition exercise, the gender gap in realized wages becomes small and statistically insignificant. The strong connection between gender differences in reservation wages and realized wages raises the question how these differences in reservation wages are set in the first place. Since traditional covariates cannot sufficiently explain the gender gap in reservation wages, we perform subgroup analysis to better understand what the driving forces behind this gender gap are.}, language = {en} } @phdthesis{Dirkwinkel2017, author = {Dirkwinkel, Lea}, title = {Trust and fairtrade consumption}, series = {Schriftenreihe Studien zum Konsumentenverhalten ; 77}, journal = {Schriftenreihe Studien zum Konsumentenverhalten ; 77}, publisher = {Kovac}, address = {Hamburg}, isbn = {978-3-8300-9599-6}, school = {Universit{\"a}t Potsdam}, pages = {XX, 235}, year = {2017}, abstract = {Wie h{\"a}ngen Vertrauen, Konsumeinstellungen und Verhalten bez{\"u}glich Fairtrade zusammen? Dies ist die grundlegende Frage, mit der sich diese Arbeit besch{\"a}ftigt. Lea Dirkwinkel analysiert die Fragestellung am Beispiel des Fairtrade-Labels, das als Symbol f{\"u}r das Produktzertifizierungssystem von Fairtrade International steht und das bekannteste Beispiel der Fairtrade-Bewegung darstellt. Die Forschungsfrage wird einerseits zur{\"u}ckgef{\"u}hrt auf die Tatsache, dass die Qualit{\"a}t von Fairtrade-G{\"u}tern durch Konsumenten nicht erfasst werden kann, und andererseits durch die sogenannte Einstellungs-Verhaltens-L{\"u}cke begr{\"u}ndet. Die Einstellungs-Verhaltens-L{\"u}cke beschreibt die kognitive Dissonanz zwischen positiven ethischen Einstellungen und Kaufintentionen sowie dem tats{\"a}chlichen Kaufverhalten und widerspricht traditionellen Einstellungs-Verhaltens-Modellen, die besagen, dass die Einstellung das Verhalten von Menschen bestimmt. Beide zuvor genannten Aspekte begr{\"u}nden in der Marketingtheorie die Relevanz von Vertrauen f{\"u}r den Konsum von Fairtrade-Produkten, aber auch anderen nachhaltigen G{\"u}tern. Die Analyse basiert auf einer Online-Datenerhebung und erfolgte anhand der Kombination aus Conjoint Analyse und Strukturgleichungsanalyse. Die innovative methodische Vorgehensweise lieferte sowohl f{\"u}r die Marketingforschung als auch f{\"u}r die Praxis relevante Ergebnisse. Zum einem wird die wichtige Rolle von Vertrauen f{\"u}r den Fairtrade-Konsum best{\"a}tigt; zum anderen erkl{\"a}rt die Arbeit, wie sich Fairtrade-Vertrauen auswirkt. Das Vertrauen in das Fairtrade-Label stellt den Ausgangspunkt f{\"u}r Vertrauensbeziehungen zwischen Fairtrade und den Konsumenten dar und wird auf die zertifizierten Produkte {\"u}bertragen. Empfehlungen, die sich daraus ergeben, konzentrieren sich auf Maßnahmen, die das Vertrauen in Fairtrade-Labels st{\"a}rken, z.B. durch die Reduzierung der Anzahl verschiedener Labels oder die verst{\"a}rkte Kommunikation der Unabh{\"a}ngigkeit von Zertifizierungsorganisationen.}, language = {en} } @phdthesis{Muehlenhoff2017, author = {M{\"u}hlenhoff, Judith}, title = {Culture-driven innovation}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-104626}, school = {Universit{\"a}t Potsdam}, pages = {143}, year = {2017}, abstract = {This cumulative dissertation deals with the potential of underexplored cultural sources for innovation. Nowadays, firms recognize an increasing demand for innovation to keep pace with an ever-growing dynamic worldwide competition. Knowledge is one of the most crucial sources and resource, while until now innovation has been foremost driven by technology. But since the last years, we have been witnessing a change from technology's role as a driver of innovation to an enabler of innovation. Innovative products and services increasingly differentiate through emotional qualities and user experience. These experiences are hard to grasp and require alignment in innovation management theory and practice. This work cares about culture in a broader matter as a source for innovation. It investigates the requirements and fundamentals for "culture-driven innovation" by studying where and how to unlock cultural sources. The research questions are the following: What are cultural sources for knowledge and innovation? Where can one find cultural sources and how to tap into them? The dissertation starts with an overview of its central terms and introduces cultural theories as an overarching frame to study cultural sources for innovation systematically. Here, knowledge is not understood as something an organization owns like a material resource, but it is seen as something created and taking place in practices. Such a practice theoretical lens inheres the rejection of the traditional economic depiction of the rational Homo Oeconomicus. Nevertheless, it also rejects the idea of the Homo Sociologicus about the strong impact of society and its values on individual actions. Practice theory approaches take account of both concepts by underscoring the dualism of individual (agency, micro-level) and structure (society, macro-level). Following this, organizations are no enclosed entities but embedded within their socio-cultural environment, which shapes them and is also shaped by them. Then, the first article of this dissertation acknowledges a methodological stance of this dualism by discussing how mixed methods support an integrated approach to study the micro- and macro-level. The article focuses on networks (thus communities) as a central research unit within studies of entrepreneurship and innovation. The second article contains a network analysis and depicts communities as central loci for cultural sources and knowledge. With data from the platform Meetup.com about events etc., the study explores which overarching communities and themes have been evolved in Berlin's start up and tech scene. While the latter study was about where to find new cultural sources, the last article addresses how to unlock such knowledge sources. It develops the concept of a cultural absorptive capacity, that is the capability of organizations to open up towards cultural sources. Furthermore, the article points to the role of knowledge intermediaries in the early phases of knowledge acquisition. Two case studies on companies working with artists illustrate the roles of such intermediaries and how they support firms to gain knowledge from cultural sources. Overall, this dissertation contributes to a better understanding of culture as a source for innovation from a theoretical, methodological, and practitioners' point of view. It provides basic research to unlock the potential of such new knowledge sources for companies - sources that so far have been neglected in innovation management.}, language = {en} } @phdthesis{Braun2014, author = {Braun, Andreas}, title = {Open innovation - an analysis of the individual level}, address = {Potsdam}, pages = {219 S.}, year = {2014}, language = {en} } @phdthesis{Hewing2014, author = {Hewing, Martin}, title = {Collaboration with potential users for discontinuous innovation : eperimental research on user creativity}, publisher = {Springer Gabler}, address = {Wiesbaden}, isbn = {978-3-658-03752-9}, pages = {173 S.}, year = {2014}, language = {en} } @phdthesis{MeierComte2012, author = {Meier-Comte, Elvire}, title = {Knowledge transfer and innovation for a western multinational company in Chinese and Indian technology clusters : identification of local and firm's knowledge transfer mechanisms to develop successful innovations}, series = {Schriften zum Internationalen Managment}, volume = {26}, journal = {Schriften zum Internationalen Managment}, publisher = {Rainer Hampp Verlag}, address = {M{\"u}nchen}, isbn = {978-3-86618-802-0}, issn = {1612-2690}, pages = {319 S.}, year = {2012}, language = {en} } @phdthesis{Alshyab2012, author = {Alshyab, Nooh}, title = {Rent, rentiersim, and the challenge of economic reforms : the case of Jordan}, publisher = {Shaker}, address = {Aachen}, isbn = {978-3-8440-1023-7}, pages = {223 S.}, year = {2012}, language = {en} } @phdthesis{Bennecke2011, author = {Bennecke, Gudrun Elisabeth}, title = {Turning wind into power : effects of stakeholder networks on renewalbe energy governanace in India}, series = {European university studies : series XXXI political science}, volume = {23}, journal = {European university studies : series XXXI political science}, publisher = {Lang Peter GmbH Internationaler Verlag der Wissenschaften}, address = {Frankfurt}, isbn = {978-3-631-61570-6}, issn = {0721-3654}, pages = {278 S.}, year = {2011}, language = {en} } @phdthesis{Wildmann2011, author = {Wildmann, Christian}, title = {Portfolioinvestitionen in Emerging Capital Markets}, series = {Schriftenreihe Finanzierung und Banken}, volume = {15}, journal = {Schriftenreihe Finanzierung und Banken}, publisher = {Verl.
