In meiner Dissertation untersuche ich, inwiefern sich der Zugang zu individuellen Absicherungsmöglichkeiten auf die informellen Unterstützungsnetzwerke zwischen Haushalten auswirkt. Diese Forschungsfrage ist vor dem Hintergrund der rasanten wirtschaftlichen Entwicklung vieler vormalig einkommensschwacher Länder von besonderer Relevanz. Sowohl um Voraussagen machen zu können, wie diese Entwicklung die soziale Struktur verändert als auch um Wohlfahrtseffekte spezifizieren zu können, ist es wichtig die Beziehung zwischen dem Zugang zu individuellen Absicherungsmöglichkeiten und der Nutzung informeller Unterstützungsnetzwerke zu verstehen. In dieser Arbeit erforsche ich diese Beziehung unter drei Gesichtspunkten. In der ersten Studie, untersuche ich die Struktur des Unterstützungsnetzwerks eines Fischerdorfes in den Philippinen. Ausgehend von einem theoretischen Netzwerkmodell, analysiere ich die Faktoren, die dazu führen, dass zwei Haushalte sich im Falle eines Schocks auf den jeweils anderen verlassen, wobei der Fokus auf dem Zugang zu alternativen Absicherungsmöglichkeiten liegt. In der zweiten Studie untersuche ich gezielt, inwieweit die Bereitschaft jemanden zu unterstützen davon beeinflusst wird, ob dieser Zugang zu individuellen Absicherungsmöglichkeiten hat. Dies wird mit Hilfe eines lab-in-the-field-Experimentes, das im ländlichen Kambodscha durchgeführt wurde, analysiert. In der dritten Studie verknüpfe ich die Unterstützungs-Entscheidungen aus dem Experiment mit dem tatsächlichen Unterstützungsnetzwerk der Experimentteilnehmer und untersuche, ob die Struktur der persönlichen sozialen Netzwerke das Verhalten im Experiment erklären kann. Zusammengefasst zeigen die drei Studien, dass mit dem Zugang zu individuellen Absicherungsmöglichkeiten Anreize abnehmen können, in informelle Unterstützungsnetzwerke zu investieren oder altruistisch Unterstützung zu gewähren. Dies hat direkte Auswirkungen auf die lokale Sozialstruktur. / In this thesis, I investigate how access to resources can affect the formation of informal support arrangements between households. This question is of particular relevance in the light of the rapid economic development that many former low-income countries recently experienced, which goes hand in hand with increasing possibilities for the population to cope with hardships individually. An understanding of the relationship between informal support and access to alternative risk management resources is crucial in order to make predictions about how this development can affect the social structure, and to specify welfare effects. In the thesis, I investigate this relationship from three different angles. First, I study the structure of mutual support arrangements in a fishing village on the Philippines (Chapter 2). Based on a model of strategic link formation I investigate which factors explain that two households engage in a mutual support arrangement with a focus on the role of households' alternative resources. In a second study, I investigate how the willingness to provide support can be affected by the availability of alternative resources, in particular individual insurance (Chapter 3). This is analyzed based on a lab-in-the-field experiment conducted in Cambodia. Different to the first study, the second study focuses on social preference motivated support. The last study conceptually links the first two studies. I relate the subjects' support decisions observed in the experiment back to the subjects' engagement in mutual support arrangements in real life and thus put the behavior in context to the social structure (Chapter 4). In summary, the studies show that with access to individual risk management options, the incentives to engage in mutual support arrangements as well as social preference motivated support can reduce, which has a direct impact on the local social structure.

This thesis is about life of homosexuals and repercussion on their mentality. It strives to compare results of my own research made in southern region and results available in professional literature. It is most of all about impact on individual's mentality. There are outlined basic information about this orientation including definition, cause, history and variants of homosexual life. I also deal with public attitude to homosexuality which undoubtedly has influence on individual's mentality. In last chapter, there is also mentions parency of homosexual couples. The goal of this thesis was to find out effect of homosexuality on individual's mentality. To achieve this goal, research questions were made. Asking method was used to collect data - depth interview. Gathered data were processed and compared with existing knowledge of this matter. Matches and disagreements between professional literature and my own research are highlited. This thesis can enrich existing knowledge of this matter and can be a resource for further research.

This thesis deals with current discourse whether methods of neuroscience generate useful tools for standard economics to understand, predict and ideally guide behavior of humans, social groups and the whole economies. An initial methodological analysis concluded that the usefulness of neuroeconomics is still only potential, since this approach is not able to answer substantial questions of economics in better way than tools existing. Following sections of thesis summarized representative research in the field of decision neuroscience in the areas of intertemporal decisions, decision-making under risk and uncertainty and the strategic interactions, and social preferences respectively. It has been demonstrated that many findings of decision neuroscience offer a partial confirmation of specific economic models already or provide inspiration for creating new ones.

Common elands (Taurotragus oryx) belong between the world's biggest antelopes. The basic social unit is created by several females with offspring, males are joining them only in the breeding period. There is a dominance hierarchy in a herd, which eliminates strong negative conflicts mainly between adult females. Except agonistic interactions, affiliative ones are taken place as well, which have positive impact on relationships in a herd. The aim of this work is t o summarize previous studies dealing with social structure and behaviour of common eland focusing on affiliative, maternal and agonistic interaction in a herd. Experimental part is focused on preferences of females for a choice of the closest companion, if the choice is influenced with age, kinship or maternal state of a female. Data were collected through direct observations of a herd of common elands on a farm Lány using 15 min scans of chosen females. Distances were measured between females and all the other herd members. Selected social behaviour of any two members of a herd was recorded using an all occurrence sampling method. The statistical analysis showed that the most (98,77 %) of interactions were negative, females preferred contactless agonistic interactions, threat and withdrawal. Allogrooming was more often found between a...

The goal of the PhD thesis is to investigate the role of behavioural economics considerations for the performance of conservation auctions. The findings of the three scientific articles suggest that behavioural economics considerations like social (distributional) preferences and reference-dependent preferences may affect the attractiveness and economic performance of conservation auctions, respectively. The results of the first and second articles are based on laboratory experiments conducted with university students, in Germany. The third article implements a field experiment to measure farmers’ preferences over Payments for Ecosystem Services (PES) allocation mechanisms and the role of fairness therein, in the context of agrobiodiversity loss in Benin.

Unterscheidet sich die Ausprägung sozialer Präferenzen zwischen Unternehmern und Nicht-Unternehmern? Beeinflussen die sozialen Präferenzen von Unternehmern welchen Geschäftstyp (soziales vs. kommerzielles Unternehmen) sie gründen? Haben soziale Präferenzen einen Einfluss auf produktive und/oder unproduktive unternehmerische Motive? Spielt die Persönlichkeitsstruktur in diesem Kontext eine Rolle? Die vorliegende Dissertation behandelt diese Fragen anhand von vier experimentellen Studien mit Unternehmern, Landwirten, Studierenden der Betriebs- und Volkswirtschaftslehre, sowie Mitarbeitern, Kollaboratoren und Investoren von Start-up-Unternehmen. Dabei werden unterschiedliche Methoden in Labor, Online, sowie „Lab-in-the field“ Experimenten angewendet. Die Ergebnisse zeigen, dass Unternehmer im Vergleich zu den anderen Testgruppen, generell stärker ausgeprägte soziale Präferenzen besitzen, insbesondere bezüglich kooperativer Eigenschaften. Darüber hinaus wird kein Zusammenhang zwischen den sozialen Präferenzen von Unternehmern und ihrer Entscheidung ein soziales oder kommerzielles Unternehmen zu gründen gefunden. / How do entrepreneurs’ social inclinations compare to those of non-entrepreneurs? Does the social preference structure of entrepreneurs provide us with information regarding the business type they choose to operate (i.e., whether they choose to run a social business versus a commercial business)? Do social preferences relate to (un)productive entrepreneurial motives? Does personality play a role in this context? This dissertation addresses these research questions by conducting four experimental studies with actual entrepreneurs, business and economics students, farmers, and start-up employees, collaborators and investors. Thereby, different methods are applied in laboratory, online, and lab-in-the-field experiments. The findings suggest entrepreneurs to hold generally stronger social tendencies, in particular in relation to cooperation. No link between social preferences and the choice of founding a social or commercial business is found.

Human sociality, with its wide scope, early ontogeny and pervasiveness across cultures, is remarkable from an evolutionary perspective. We form bonds with other individuals and live in large social groups. We help, empathise with and share our resources with others, who are unfamiliar and genetically unrelated to us. It has been suggested that interpersonal coordination and rhythmic synchronisation of movements may be one proximate mechanism that enables such widespread human sociality and facilitates cooperation. In the last decade, considerable research has examined the effect of movement synchrony on social bonding and cooperation. However, when this thesis started, there was virtually no experimental study investigating the ontogeny of the movement synchrony-social bonding link, which is proposed to have deep evolutionary roots and important, long-lasting consequences in social life. This thesis aims to investigate the effects of movement synchrony on social bonding and cooperative behaviour across different time points in ontogeny. Three experimental studies were conducted examining infancy, early childhood and middle childhood. Each study explored a different aspect of social bonding and cooperation based on the motor, social and cognitive developments that mark that age group. Study 1a found that at 12 months of age, infants prefer individuals who move in synchrony with them, when the individuals are social entities, but not when they are non-social. Study 1b showed no preferences for synchrony at 9 months in either social or non-social contexts, however. Study 2 revealed that in early childhood, performing synchronous movements actively with a peer facilitates helping behaviour among the children, as well as eye contact and mutual smiling during the interaction. Finally, Study 3 showed that the social bonding effects of movement synchrony applied to inter- group settings and that performing synchronous movements with out-groups increased bonding towards the out-group in middle childhood. This thesis followed an interdisciplinary, integrative and naturalistic approach, where (i) literature from a wide range of disciplines motivated and guided the present research; (ii) links between motor, social and cognitive aspects of development, which are often investigated separately, are formed; and (iii) the experiments were designed in ways that represent the real-life occurrences of the investigated phenomena. The current findings provide the first substantial evidence that movement synchrony facilitates social bonding and cooperation in childhood and thereby provides a foundation for future research.

La tesi presenta alcuni dei risultati di un esperimento longitudinale condotto in due carceri statunitensi tra settembre 2015 e giugno 2016. L’obiettivo dell’analisi è testare lo studio delle preferenze sociali nella cornice dell’Economia Comportamentale e della teoria dei giochi (osservazione diretta del comportamento dei soggetti chiamati a compiere delle scelte in alcune situazioni selezionate), piuttosto che attraverso risposte a questionari auto valutativi. Infatti vengono messe in relazione i comportamenti osservati nei giochi e le spiegazioni che i soggetti intervistati danno di essi. Attraverso analisi statistica si può arrivare a dire che i comportamenti osservati nei giochi non sono sempre sufficienti per evidenziare le preferenze sociali dei soggetti, così come, del resto, non lo sono le risposte narrative. La conclusione che viene tratta dall’elaborato è che osservazione diretta dei comportamenti e analisi delle narrative personali dei soggetti sono due elementi ugualmente importanti per la comprensione delle preferenze sociali e che, lungi dall’escludersi a vicenda, si completano. / The thesis presents some of the results of a longitudinal experiment conducted in two U.S. prisons between September 2015 and June 2016. The objective of the analysis is to test the efficacy of studying social preferences in the framework of behavioral Economics and game theory (direct observation of the behaviour of the subjects asked to make choices in real situations), rather than through self-evaluative questionnaires and surveys. In fact, the analysis links the behaviors observed in the games and the explanations given by the subjects. In general it can be said that the behaviors observed in the games are not always sufficient to highlight the social preferences of the subjects, as well as, moreover, are not the narrative answers. The conclusion that comes from the elaborate is that direct observation of the behaviors and analysis of the personal narratives of the subjects are two equally important tools in the study social preferences and that, far from being mutually exclusive, they complement each other.
