The dissertation focuses on identifying a typical generation Y representative on the financial products market and, on the basis of these characteristics, creates a model of generation Y customer on the financial products market in the context of behavioral economics. Based on the literature research, the terms "generation Y" and "selected knowledge of behavioral economics" were defined. The literature research also led to creating a questionnaire that was used to obtain primary research data. Secondary research has characterized consumers on the financial products market. Secondary research focused on the form of payment; relationship to technologies; cash and cashless payments; relation to cryptocurrencies; relation to savings; digital banking transformation; financial behavior of Czech households. Primary research has focused on obtaining information in the field of behavioral economics, specifically the prejudices of the Czech generation Y; and on what financial market products the Czech generation Y uses and generation’s relationship to risks, provided information and satisfaction with products. Primary research data was used as input data for structural equation modeling. Because of this method, mutual relationships between selected products have been found; customer characteristics and heuristics. The benefit of this work lies in the characteristics of customers in the selected market. It is a sector that is slowly entering the digitalization period, and understanding the young generation, which now accounts for a third of its customers, is crucial for companies. If companies are not able to respond to the changing needs of the younger generations, they can lose their customers and hence revenue.

This thesis intends to verify and quantify relationship between microeconomics, macroe- conomics and social variables with annual beer consumption per capita. To assess dif- ferences in tastes in groups of countries, the concept of beer, wine and spirit drinking countries is used to separate the influences. Firstly, the general model for all European countries is estimated with the use of panel data techniques on data from 2000 to 2013. The results and findings from the first model are subsequently used as a building blocks for specific model for The Czech Republic. The Czech Republic has over a long period the highest annual consumption per capita. Still the share consumed in hospitality expe- riences persistent downward trend. All data are collected on annual basis and with only country-aggregated level of detail.

There are ongoing discussions about a new reform of the mandatory fully funded individual accounts in the Swedish public pension system. Since the initial round in 2000, several funds have been excluded from the platform due to deceptive, and sometimes criminal, behavior towards the consumers. This paper analyzes which individuals that have invested in these funds, examines possible explanations for this, and sheds light on the current structure of the Premium Pension Scheme. By using a rich dataset on 650,000 individuals that consist of both those who have been in six particular dubious funds and a random sample of the rest of the Swedish pension savers, the variables of interest are evaluated in a logistic setting. The results show that individuals who are men, unmarried, divorced, in their older-middle age, have lower-incomes, live in rural areas, and the North of Sweden are more likely to have invested in one of the dubious funds. The results also reveal that some funds have clearer target-groups, while others have targeted more randomly. The study emphasizes the need for improving people’s financial decision-making through improved information.

This study investigates if attitudes towards the pandemic recommendations made by the Public Health Agency of Sweden and if the estimation of their duration differ before and after a Covid-19 vaccination. The participants contributed to the study by filling out a questionnaire. A mass vaccination is a rare occurrence and few empirical studies have been conducted. A risk regarding a mass vaccination is that it can result in a premature relaxed mindset towards the recommendations, which can lead to an increased spread of the virus. To investigate this, we compared the responses from the participants who filled out the questionnaire before and after the Covid-19 vaccination. The results showed no differences in the attitudes towards the recommendations in the two groups, however tendencies of differences regarding the estimation of duration of the pandemic recommendations was discovered. Thus, we could not detect any large effects of a more relaxed mindset towards the recommendations, however we cannot exclude smaller effects. The results do not support that stricter recommendations should be introduced in order to counteract a more relaxed attitude. / Studien ämnar undersöka om inställningen till Folkhälsomyndighetens rekommendationer och uppskattningen av pandemirekommendationernas varaktighet skiljer sig åt före respektive efter vaccination mot covid-19. Deltagarna medverkade i studien genom att svara på ett frågeformulär.En massvaccinering är en sällsynt förekomst och få empiriska studier har genomförts. En risk vidgenomförandet av en massvaccinering är att den kan resultera i en för tidigt avslappnad inställning till rekommendationerna, vilket kan leda till en ökad smittspridning i samhället. Resultatet visade inte på några skillnader i inställningen till rekommendationerna mellan de två grupperna, dock fanns det tendenser till skillnader angående uppskattningen av pandemirekommendationernasvaraktighet. Således, utifrån studiens resultat, påvisades inte någon stor effekt av en avslappnad inställning efter en massvaccinering men det går inte att utesluta mindre effekter. Studiens resultatstyrker inte att strängare rekommendationer bör införas i en vaccinationsfas för att motverka en avslappnad inställning.

Diese Arbeit untersucht den Einfluss verhaltensökonomischer Aspekte und Bildung für die finanzielle Entwicklung. Sie besteht aus vier Kapiteln, welche jeweils ein separates Forschungspapier darstellen. Die Kapitel decken folgende Themen ab: Determinanten einer impulsiven Kreditaufnahme, Hindernisse bei finanzieller Inklusion, die Auswirkungen von finanzieller Bildung und die finanziellen Folgen eines Schocks. Alle Kapitel nutzen Umfragedaten. Außerdem nutzen einige Kapitel experimentelle (Labor-)Ergebnisse. Nach einer Einleitung untersucht Kapitel zwei die Rolle von Selbstkontrolle und finanzieller Bildung bei einer impulsiven Kreditaufnahme und analysiert experimentelle Daten, die in einem Labor in Berlin erhoben wurden, sowie Umfragedaten aus der Innovations-Stichprobe des Sozio-oekonomischen Panels. Kapitel drei trägt zu einem besseren Verständnis der Determinanten und Hindernisse für die Nutzung von Mobile Money in einem einkommensschwachen Land bei, wobei es auch den Beitrag von Mobile Money zur finanziellen Inklusion betrachtet. Da Bildung die Wahrscheinlichkeit erhöht, dass neue Technologien genutzt werden, könnte finanzielle Bildung weitere Bemühungen zur finanziellen Inklusion und zum Verbraucherschutz für die finanzielle Entwicklung sinnvoll ergänzen. Daher ist es wichtig, die Auswirkungen von Programmen zu bewerten, die auf finanzielle Bildung abzielen. Dafür werden in Kapitel vier die Auswirkungen eines Finanzbildungsprogramms und seine Spillover-Effekte anhand einer randomisierten kontrollierten Studie analysiert. Kapitel fünf beleuchtet die Auswirkungen der COVID-19-Pandemie auf das finanzielle Wohlergehen und die Technologienutzung von Kleinstunternehmern. Die in Kapitel drei bis fünf verwenden Daten wurden in zwei groß angelegten Erhebungswellen im ländlichen Uganda erhoben. / This thesis focuses on the role of behavioral characteristics and education for financial development. It consists of four chapters, each being a separate research paper, covering related areas: determinants of impulsive borrowing, barriers to financial inclusion, the impact of financial education, and the financial consequences due to a shock. All chapters use survey evidence, and some include (lab) experimental findings. After the introduction, Chapter two investigates the role of self-control and financial literacy for impulsive borrowing, analyzing experimental data collected in a laboratory in Berlin and survey data provided by the German Socio-Economic Panel's Innovation Sample. Chapter three contributes to a better understanding of the determinants and barriers to mobile money adoption in a low-income country, and the contribution of mobile money services to financial inclusion. As education makes it more likely to adopt new technologies, financial education could complement other financial inclusion and consumer protection efforts for financial development. Thus, it is relevant to assess the consequences of programs targeting financial education. Therefore, chapter four analyzes the impact of a financial education program and its spillover effects via a randomized controlled trial. Chapter five sheds light on the consequences of the COVID-19 pandemic on the financial well-being and technology adoption of micro-entrepreneurs. Chapter three to five use data collected in two large-scale survey waves in rural Uganda.

Cette thèse étudie les facteurs d’offre et de demande associés au recours au dépistage du cancer du sein. Parmi les facteurs d’offre, j’examine comment la coexistence du dépistage organisé au côté du dépistage individuel influence le contenu de l’examen de dépistage ainsi que le recours régulier au dépistage. En plus des facteurs de demande tels les caractéristiques socioéconomiques, une attention particulière est portée à la possibilité d’expliquer le recours régulier au dépistage par les préférences face au risque et temporelles ainsi que les perceptions. À partir de régularités psychologiques identifiées dans les travaux d’économie comportementale et de psychologie, trois interventions de type nudge sont testées dans le cadre d’une expérience randomisée sur le terrain visant à augmenter le taux de dépistage dans le programme national. / This thesis explores supply and demand factors associated with the use of breast cancer screening. Among the supply factors, I examine how the coexistence of organized and opportunistic screenings influences the content of the screening exam and screening regularity. Besides the usual demand factors such as socioeconomic characteristics, a special attention is being given to the possibility of explaining screening regularly by individuals’ risk and time preferences and perceptions. Based on psychological patterns identified in the literature in behavioral economics and psychology, three nudge interventions are tested in a randomized field experiment to increase the national program uptake rate.

There is a student loan debt problem in the United States. Seven million student borrowers are in default and another 14 million are delinquent on their loans. A high level of college loan debt leaves students with insurmountable payments and holds them back from starting a family, buying a home, or saving for retirement. The problem is that financial managers may not understand the student loan decision process well enough to help students make a loan decision that prevents an unmanageable level of debt. The purpose of this study was to explore and understand the student's loan decision process using a conceptual framework that contrasts rational choice theory and behavioral economics within the Blackwell, Miniard, and Engel's consumer decision model. This exploratory study was designed to answer research questions about how students perceived the forces that might influence the decision. A qualitative case study was conducted and purposeful sampling was used to identify 28 undergraduate students who had a student loan at a university in the Rocky Mountain region. The students were interviewed, the data coded, and the coded data were analyzed to identify themes. The data were used to diagram the decision process and identify decision variables. The findings indicated that students were pragmatic in their loan decisions, but they were not rational actors. The research highlighted 3 behavioral economic themes: the power of intention, herding, and complexity resulting in the use of the satisficing and default heuristics. The contributions of this study could be of interest to financial managers, parents of students, and students planning to enter college. Preventing unmanageable student debt could bring positive social change to the students and their families.

The phenomenon of "fake news", or misleading online content, is increasingly worrisome due to its large-scale socio-economic impact. Researchers and practitioners attempted to understand what drives the virality and believability of fake news and how to reduce its influence. This research aims to shed light on these questions. Building upon a theoretical account positing that people share fake news because they simply fail to engage in deliberate thinking, we designed an accuracy prompt intervention to encourage people to think effortfully. In a pre-registered study conducted via Prolific (N = 520), we find limited evidence supporting accuracy prompts stylized as warning labels, but only for increasing sharing discernment in true, not fake news. The veracity of news articles does not impact sharing intentions, despite having a sizeable effect on accuracy judgments. This and other findings support the dual processing theory of cognition in the context of fake news. Predispositions towards more intuitive thinking increased belief in fake news and higher distrust in true news. Conversely, a better ability to engage in effortful thinking increases truth discernment. In addition, confirmation bias decreases truth discernment and increases sharing intentions. Politically concordant true headlines are...

This master thesis deals with the price prediction on financial markets. It describes automated trading systems based on technical analysis and discusses a soft computing approach to construction of such systems. Also, this thesis combines conventional trading strategies with the fuzzy logic. The practical part of this thesis contains also a framework for composing, simulation and analysis of the automated trading strategies. The simulator contained in this framework is implemented in the Java language and based on DEVS formalism. Because of this, there is a possibility to embed real-time components into the trading model. This work contains also a database of historical financial data and tools for their automatic actualization.

In der ersten Abhandlung untersuche ich die Auswirkungen von Informationsfriktionen und Aufwandskosten auf die Effektivität von Steuervergünstigungen bei der Förderung von Spenden für wohltätige Zwecke. Mittels eines groß angelegten Umfrageexperiments und einem Feldexperiment prüfe ich empirisch, ob die Verringerung von Informationsfriktionen durch Hervorhebung von Steuervergünstigungen und Bereitstellung von Informationen über die Höhe von Steuervergünstigungen Spendenentscheidungen verändert. Meine Ergebnisse zeigen, dass die Spenden steigen, wenn Steuervergünstigungen hervorgehoben und Informationen bereitgestellt werden. Ich lege dar, dass der Hauptverhaltensmechanismus, der Informationsfriktionen zugrunde liegt, Unaufmerksamkeit ist. Die zweite Abhandlung ist eine gemeinsame Arbeit mit Steffen Altmann, Armin Falk, Paul Heidhues und Rajshri Jayaraman. In dieser Arbeit untersuchen wir die Auswirkungen von voreingestellten Beträgen auf Spenden für wohltätige Zwecke in einem groß angelegten Feldversuch auf einer Online-Spendenplattform. Wir beobachten eine starke Auswirkung von voreingestellten Beträgen auf das individuelle Verhalten, stellen jedoch fest, dass die Gesamtspende nicht von voreingestellten Beträgen beeinflusst wird. Mit einem Strukturmodell wird untersucht ob die Personalisierung von voreingestellten Beträgen die Spendeneinnahmen erhöhen kann. In der dritten Abhandlung, die in Zusammenarbeit mit Rajshri Jayaraman und Michael Kaiser verfasst wurde, untersuchen wir gemeinnützige Spenden für Naturkatastrophen auf einer großen Online-Plattform. Wir beobachten, dass der Großteil der Spenden für wohltätige Zwecke an einen winzigen Teil der Naturkatastrophen geht, bei denen es sich in der Regel um besonders schwere Katastrophen handelt, über die in den Medien berichtet wird. Unter Verwendung eines Ereignisstudiendesigns finden wir Hinweise, die mit zwei Erscheinungsformen der Spenderermüdung übereinstimmen, jedoch nicht mit einer dritten. / In the first essay, I study the implications of information frictions and hassle costs for the effectiveness of tax incentives in encouraging charitable giving. Empirically, I test whether mitigating information frictions by making tax incentives more salient and by providing information on the magnitude of tax incentives alters donation decisions by conducting a large-scale survey experiment, representative of the German adult population and I complement this with a large-scale field experiment on an online donation platform. My findings indicate that when tax incentives are made salient, and when information is provided, donations increase. I find that the main behavioral mechanism underlying information frictions is inattention. Analyzing who responds more to salience and information provision shows that it is predominantly individuals that face lower hassle costs and have high incomes. The second essay is joint work with Steffen Altmann, Armin Falk, Paul Heidhues, and Rajshri Jayaraman. In this paper, we study the effects of defaults on charitable giving in a large-scale field experiment on an online fundraising platform. We document a strong effect of defaults on individual behavior but nevertheless find that aggregate donation levels are unaffected by defaults. In contrast, co-donations increase in the default amount. We complement our experimental results with a structural model that investigates whether personalizing defaults based on individuals’ donation histories can increase donation revenues. In the third essay, which is joint work with Rajshri Jayaraman and Michael Kaiser, we investigate charitable donations to natural disasters on a large online platform. We document that the bulk of charitable donations go to a tiny fraction of natural disasters, which tend to be severe disasters that receive media coverage. Using an event study design, we find evidence consistent with temporal fatigue and donor fatigue, but not with crowding out.
