TY - THES A1 - Döring, Matthias T1 - The public encounter T1 - Dynamiken von Bürger-Staat-Interaktionen BT - dynamics of citizen-state interactions N2 - This thesis puts the citizen-state interaction at its center. Building on a comprehensive model incorporating various perspectives on this interaction, I derive selected research gaps. The three articles, comprising this thesis, tackle these gaps. A focal role plays the citizens’ administrative literacy, the relevant competences and knowledge necessary to successfully interact with public organizations. The first article elaborates on the different dimensions of administrative literacy and develops a survey instrument to assess these. The second study shows that public employees change their behavior according to the competences that citizens display during public encounters. They treat citizens preferentially that are well prepared and able to persuade them of their application’s potential. Thereby, they signal a higher success potential for bureaucratic success criteria which leads to the employees’ cream-skimming behavior. The third article examines the dynamics of employees’ communication strategies when recovering from a service failure. The study finds that different explanation strategies yield different effects on the client’s frustration. While accepting the responsibility and explaining the reasons for a failure alleviates the frustration and anger, refusing the responsibility leads to no or even reinforcing effects on the client’s frustration. The results emphasize the different dynamics that characterize the nature of citizen-state interactions and how they establish their short- and long-term outcomes. N2 - Die vorliegende Arbeit setzt sich mit der direkten Interaktion zwischen BürgerInnen und Verwaltungen auseinander. Auf Basis eines umfassenden Modells, das verschiedene Perspektiven auf die Dynamiken dieser “public encounter” beschreibt, werden ausgewählte Forschungslücken hervorgehoben. Die drei Artikel, die diese Dissertation konstituieren, fokussieren diese Lücken. Dabei spielt die Frage nach den notwendigen Kompetenzen von BürgerInnen, die es ermöglichen, erfolgreich und auf Augenhöhe mit Verwaltungen interagieren zu können, eine wichtige Rolle. Die Relevanz verschiedener Dimensionen wird herausgearbeitet und mit Hilfe eines Survey-Instruments validiert. In einer weiteren Studie zeigt sich, dass VerwaltungsmitarbeiterInnen BürgerInnen bevorzugen, die dank dieser Kompetenzen besser auf Interaktionen vorbereitet sind. Aufgrund der besseren Vorbereitung sowie der Fähigkeit, ihr Gegenüber vom Nutzen des Antrags zu überzeugen, gelingt es BürgerInnen mit einer hohen Kompetenz, eine höhere Erfolgswahrscheinlichkeit im Sinne der organisationalen Ziele zu signalisieren. Der dritte Artikel beleuchtet die Dynamik der Kommunikationsstrategien von MitarbeiterInnen im Falle von Fehlern bei der Erbringung von Dienstleistungen. Die Studie stellt heraus, dass verschiedene Kommunikationsstrategien zur Wiedergutmachung von Fehlern unterschiedliche Effekte auf das Frustrationsniveau der KlientInnen haben. Hierbei zeigt sich, dass die bewusste Übernahme von Verantwortung sowie die Erläuterung der Ursachen des Fehlers die Frustration senken, während das Abwälzen der Verantwortung keinen bzw. sogar einen verstärkenden Effekt auf die Frustration hat. Die Ergebnisse verdeutlichen die Dynamiken, die bei der Interaktion zwischen BürgerInnen und Verwaltungen entstehen und für das kurz- und langfristige Ergebnis dieser Interaktionen maßgeblich sein können.

The test data required for this has an uncertain influence on the simulation results, because the feasable search space can be changed drastically by small variations of the initial problem model. Methods could benefit from this to varying degrees. This speaks in favor of defining standardized and reusable test data for JSP problem classes, which in turn requires a systematic describability of the test data in order to be able to compile problem adequate data sets. This article looks at the test data used for comparing methods by literature review. It also shows how and why the differences in test data have to be taken into account. From this, corresponding challenges are derived which the management of test data must face in the context of JSP research.

The paper employs an affordance-based view that allows for the identification and structuring of hidden, emergent attributes of the scenario technique beyond the intended ones. The suggested framework distinguishes between affordances (1) that are intended by the organization and relate to its goals, (2) that emergently generate organizational benefits, and (3) that do not relate to organizational but individual interests. Also, constraints in the use of scenarios are discussed. Affordance theory’s specific lens shows that the emergence of such attributes depends on the users’ specific intentions.

For technology addiction, researchers have developed a variety of self-reported scales in areas such as Internet, smartphones, videogames, social network sites (SNS) or television. However, no uniform criteria or definition exists for technology addiction. Utilized dimensions of technology addiction, to measure specific outcomes, lack a conceptual standard. Therefore, linkages between technology areas dimensions have not been examined in a broader way by the research community, in order to develop a uniform technology addiction scale. In this regard, firstly, a theoretical model was developed in order to extract common technology dimensions. Secondly, a systematic literature review in the areas of Internet, smartphone, video games and SNS was conducted in order to extract the dimensions used. To identify relevant studies, nine databases (GoogleScholar, ScienceDirect, PubMed, EmeraldInsight, Wiley, SpringerLink, ACM, iEEE and JSTOR) were searched, producing 4698 results, and 50 studies met the inclusion criteria. Thirdly, the developed theoretical model was utilized in order to determine the dimension in each of the identified scales. Based on analysis of the dimensional distributions, the findings suggest that there are common dimensions across areas of technology such as “compulsive use” and “negative outcomes” but also differences in dimensions across areas such as “social comfort” and “mood regulation”, which are more used in the area of SNS. Moreover, new dimensions such as “cognitive absorption” or “utility and function loss" for technology addiction were extracted, which should be considered as these have not yet been researched in a broader way. In addition, no gold standard for the conceptual criteria or definition for technology addiction has been developed yet. N2 - Digitale Medien durchdringen immer mehr das alltägliche Leben. Dadurch entsteht die Sorge, dass sich verschiedene Formen von Technologiesucht für Menschen herausbilden. Dabei haben Forscher eine Vielzahl von Messinstrumenten in den Bereichen Internet, Smartphones, Videospiele, Social Network Sites (SNS) oder Fernsehen entwickelt, um Süchte zu messen. Jedoch gibt es keine einheitlichen Kriterien oder eine standardisierte Definition der Technologiesucht, um diese für spezifische Dimensionen zu erfassen. Dies ist einer der Gründe warum die Forschungsgemeinschaft die Zusammenhänge zwischen den einzelnen Dimensionen nicht weiter untersucht hat, um einheitliche Messinstrumente zu entwickeln. Aus diesem Grund hat diese Studie zunächst ein theoretisches Modell entwickelt, um gemeinsame technologische Dimensionen zu extrahieren. Danach wurde eine systematische Literaturrecherche in den Bereichen Internet, Smartphone, Videospiele und SNS durchgeführt, um die verwendeten Dimensionen zu ermitteln. Um relevante Studien zu identifizieren, wurden neun Datenbanken (GoogleScholar, ScienceDirect, PubMed, EmeraldInsight, Wiley, SpringerLink, ACM, iEEE und JSTOR) durchsucht, die 4698 Ergebnisse lieferten. 50 dieser Messinstrumente haben die gesetzten Kriterien erfüllt. Darauffolgend ist das entwickelte theoretische Modell verwendet worden, um die Dimension in den 50 identifizierten Messinstrumenten zu bestimmen. Basierend auf der Analyse der dimensionalen Verteilung deuten die Ergebnisse darauf hin, dass es gemeinsame Dimensionen in Technologiebereichen wie z.B. "zwanghafte Nutzung" und "negative Ergebnisse” gibt. Aber es gibt auch Unterschiede in der Verteilung in den Dimensionen der Technologiebereiche. Zum Beispiel sind "sozialer Komfort" und "Stimmungsregulierung", im Bereich der SNS stärker vertreten. Zudem sind neue Dimensionen der Technologiesucht extrahiert worden. Zum Beispiel die "kognitive Absorption” oder der "Nutzen- und Funktionsverlust”, welche noch nicht breiter erforscht worden sind. Darüber hinaus ist noch kein Standard für die konzeptionellen Kriterien oder die Definition der Technologiesucht entwickelt worden.

T2 - CEPA Discussion Papers N2 - As the policy debate on entrepreneurship increasingly centers on firm growth in terms of job creation, it is important to better understand which variables influence the first hiring decision and which ones influence the subsequent survival as an employer. Using the German Socio-economic Panel (SOEP), we analyze what role individual characteristics of entrepreneurs play in sustainable job creation. While human and social capital variables positively influence the hiring decision and the survival as an employer in the same direction, we show that none of the personality traits affect the two outcomes in the same way. Some traits are only relevant for survival as an employer but do not influence the hiring decision, other traits even unfold a revolving door effect, in the sense that employers tend to fail due to the same characteristics that positively influenced their hiring decision.

BT - The Long-Term Business and Innovation Potential of Subsidized Start-Ups out of Unemployment T2 - CEPA Discussion Papers N2 - From an active labor market policy perspective, start-up subsidies for unemployed individuals are very effective in improving long-term labor market outcomes for participants. From a business perspective, however, the assessment of these public programs is less clear since they might attract individuals with low entrepreneurial abilities and produce businesses with low survival rates and little contribution to job creation, economic growth, and innovation. In this paper, we use a rich data set to compare participants of a German start-up subsidy program for unemployed individuals to a group of regular founders who started from nonunemployment and did not receive the subsidy. The data allows us to analyze their business performance up until 40 months after business formation. We find that formerly subsidized founders lag behind not only in survival and job creation, but especially also in innovation activities. The gaps in these business outcomes are relatively constant or even widening over time. Hence, we do not see any indication of catching up in the longer run. While the gap in survival can be entirely explained by initial differences in observable start-up characteristics, the gap in business development remains and seems to be the result of restricted access to capital as well as differential business strategies and dynamics. Considering these conflicting results for the assessment of the subsidy program from an ALMP and business perspective, policy makers need to carefully weigh the costs and benefits of such a strategy to find the right policy mix.

This article presents a comparison between subjects restricted to playing pure strategies and subjects allowed to play mixed strategies in a one-shot symmetric PD laboratory experiment. Subjects interact with 10 other subjects and take their decisions all at once. Because subjects in the mixed-strategy treatment group are allowed to condition their level of cooperation more precisely on their beliefs about their counterparts’ level of cooperation, we predicted the cooperation rate in the mixed-strategy treatment group to be higher than in the pure-strategy control group. The results of our experiment reject our prediction: even after controlling for beliefs about the other subjects’ level of cooperation, we find that cooperation in the mixed-strategy group is lower than in the pure-strategy group. We also find, however, that subjects in the mixedstrategy group condition their cooperative behaviour more closely on their beliefs than in the pure-strategy group. In the mixed-strategy group, most subjects choose intermediate levels of cooperation.

It is thus a crucial factor for entrepreneurs when pursuing and exploiting their business opportunities and to realize potential economic gains and benefits. Using rich data on a representative sample of German business founders, we investigate the determinants of entrepreneurial persistence. Next to observed survival we also construct a hybrid persistence measure capturing also the motivational dimension of persistence. We analyze the influence of individual-level (human capital and personality) and business-related characteristics on both measures as well as their relative importance. We find that the two indicators emphasize different aspects of persistence. For the survival indicator, the predictive power is concentrated in business characteristics and human capital, while for hybrid persistence, the dominant factors are business characteristics and personality. Finally, we show that results are heterogeneous across subgroups. In particular, formerly-unemployed founders do not differ in survival chances, but they are more likely to lack a high psychological commitment to their business ventures.

We study one particular context in which ignorance can be beneficial: iterated strategic interactions in which voluntary cooperation may be sustained into the final round if players voluntarily forego knowledge about the time horizon. We experimentally examine this option to remain ignorant about the time horizon in a finitely repeated two-person prisoners’ dilemma game. We confirm that pairs without horizon knowledge avoid the drop in cooperation that otherwise occurs toward the end of the game. However, this effect is superposed by cooperation declining more rapidly in pairs without horizon knowledge during the middle phase of the game, especially if players do not know that the other player also wanted to remain ignorant of the time horizon.

Using propensity score matching (PSM) as our main empirical approach, we provide estimates of long-term effects of the post-reform subsidy on individual employment prospects and labor market earnings up to 40 months after entering the program. Our results suggest large and persistent long-term effects of the subsidy on employment probabilities and net earned income. These effects are larger than what was estimated for the pre-reform program. Extensive sensitivity analyses within the standard PSM framework reveal that the results are robust to different choices regarding the implementation of the weighting procedure and also with respect to deviations from the conditional independence assumption. As a further assessment of the results’ sensitivity, we go beyond the standard selection-on-observables approach and employ an instrumental variable setup using regional variation in the likelihood of receiving treatment. Here, we exploit the fact that the reform increased the discretionary power of local employment agencies in allocating active labor market policy funds, allowing us to obtain a measure of local preferences for SUS as the program of choice. The results based on this approach give rise to similar estimates. Thus, our results indicating that SUS are still an effective active labor market program after the reform do not appear to be driven by “hidden bias”.

This study finds a loyalty-enhancing effect of retroactive price-reduction schemes only if the buyers ex-ante expected that entering into the scheme would maximize their monetary gain, but later learn that they should leave the scheme.

We discuss the short-run effects of this new minimum wage on a wide set of socio-economic outcomes, such as employment and working hours, earnings and wage inequality, dependent and self-employment, as well as reservation wages and satisfaction. We also discuss difficulties in the implementation of the minimum wage and the measurement of its effects related to non-compliance and suitability of data sources. Two years after the minimum wage introduction, the following conclusions can be drawn: while hourly wages increased for low-wage earners, some small negative employment effects are also identifiable. The effects on aspired goals, such as poverty and inequality reduction, have not materialized in the short run. Instead, a tendency to reduce working hours is found, which alleviates the desired positive impact on monthly income. Additionally, the level of non-compliance was substantial in the short run, thus drawing attention to problems when implementing such a wide-reaching policy.

In order to confirm this hypothesis, a panel data regression analysis is performed that suggests that unions significantly influence the distribution of income in developed countries.
