The purpose of this study is to examine how people express their beliefs in crystals through the comments section of one of Sweden's largest crystal retailers. The aim of the thesis is to gain a deeper understanding of contemporary religious expressions of crystal users. In total the study material consists of 172 comments collected from the website Ohlamoon.se written between January 2019 and September 2023. The study is conducted using a thematic content analysis and follows an abductive approach. Stark & Finke's Rational Choice Theory (2000) has been employed as the primary theory against which analysis questions are posed, the thesis also utilizes Heelas & Woodhead's (2005) description of The Subjective Turn as a secondary theory against which the results are discussed. The conclusions from the study revealed that crystals are described as possessing positive qualities that in various ways, reinforce, support, or comfort users. In this way crystals can be likened to personal pillars of support that actively contribute to users' lives with their properties and agency. Users form personal relationships and feelings of affection towards the crystals, utilizing their energy and presence in daily life as well as during meditation and rituals to achieve a sense of deeper spiritual states.

The politics of outer space has in recent years been given attention from political elites and scientist due to increasing usage and reliance on space based assets, and due to increasing numbers of actors trying to utilize the benefits of space. Concerns have been raised if the increasing military usage of space will lead to a future weaponization of space, making some political leaders and scholars claiming the inevitability of space weaponization.  In this thesis I investigate why the United States of America this far has chosen not to weaponize space based on the strategical setting of outer space politics. The research question guiding this thesis reads: What strategic considerations explain the US decision not to weaponize outer space? In order to evaluate the strategic setting and US strategical considerations I apply Game Theory and Non-Formal Rational Choice Theory to highlight what is causing the greatest space faring nation not to weaponize space. I empirically base this study on official space policy documents and one report written by an official commission to asses US national security space management.  Based on the strategic setting of outer space politics and US strategical considerations it is found that the US has not commenced a process leading to the weaponization of space since such development would not increase its national security, but rather in several ways decrease it. I conclude that a process of space weaponization is not likely to be initiated by the US in the current strategical setting.

In this thesis, economic theory and models will be used to analyze trends of religious growth and decline within the United States. These theories and models, such as Rational Choice Theory, will be applied in order to better understand and gain new insight into shifts and changes within the religious landscape of the United States. Recent trends of growth and decline within Protestantism, the most prominent Christian tradition in America, will be the focus of the investigation. As its main focus, this thesis will ultimately demonstrate that the trends of decline in the mainline Protestant tradition opposed to the trends of growth in the evangelical Protestant tradition can be best understood by focusing on the unique relationship between a religious organization’s degree of tension with society and that organization’s congregational attendance.

Abstract: As China is facing environmental problems, they are producing positive policies in order to stimulate the sales of electric vehicles. In addition, China is one of the largest electric vehicle markets in the world and the electric vehicles market has a promising growth potential. In light of this, this thesis aims to investigate the factors affecting Chinese consumers’ willingness to purchase electric vehicles. This thesis draws on rational choice theory to analyze the six determining factors including driving range of electric vehicles, charging infrastructure, purchase cost, government financial incentives, individual environmental awareness and perceived social influence, as electric vehicles are not cheap goods and make consumers take full consideration before buying. This study adopts a quantitative approach and conducts a survey to investigate this topic. Based on 249 online questionnaires from Chinese consumers, this study employs SPSS to conduct a regression analysis to test the six determining factors. The empirical results indicate that charging infrastructure, government financial incentives, individual environmental awareness and perceived social influence have significant impact on Chinese consumers’ willingness to purchase electric vehicles, while our results do not show that the driving range of electric vehicles and purchase cost matters in influencing Chinese consumers’ willingness to purchase electric vehicles. Meanwhile, this study contributes to the research on the consumption of electric vehicles by providing an empirical context of China, considering rational choice theory and understanding perceived social influence. Also, this study provides relevant suggestions to electric vehicle manufacturers and the Chinese government about how to encourage the Chinese to adopt electric vehicles in China.

This thesis studies how young adults in today's Swedish Pentecostal congregations describe their beliefs and their congregational life. The thesis applies a theoretic frame of Rational Choice Theory and compares the results with previous research/adjacent studies close to the field. The relevance of this thesis lies in that research on young adults in the Swedish Pentecostal movement is a comparatively unexplored area. The reason to write about young adults in the Swedish Pentecostal movement is rooted in the prospect that this thesis could be a starting point for further studies on young adults in the Swedish Pentecostal movement. The thesis was a qualitative and quantitative multi-method study. The thesis is based on interviews and a questionnaire survey in order to present how young adults in today's Swedish Pentecostal churches describe their beliefs and their congregational life. The thesis identifies some issues that can be raised and investigated in further research on thistopic. Summary of the results The young adults describe that their faith becomes stronger by being part of a Pentecostal congregation. The community of the congregation, both in the smaller and the broader context, confirms the faith which makes their belief stronger. They perceive God as a protector and caretaker, and that God listens to their prayers and cares about them. The subjective part of the faith (the personal relationship with God) they experience as necessary, but they feel that the subjective relationship with God both can be experienced in the church community and solitude. Most of the young adults say they would consider switching the congregation (leave the congregation) if they would not thrive in the congregation or if it would not meet their expectations and needs. The interviews show that the respondents indicate certain preferences that they want to get satisfied and they want to belong to a congregation that can fulfil this. Getting their preferences and needs met is the key to the congregations if they want young adults to stay. The young adults are investing and giving time and commitment to their congregations and want this to generate something back. Most of them thrive in their congregations, but there is room for improvement. Their faith is strong. They are willing to invest in God and then consequently also in their congregations. / <p>Godkännandedatum 2019-06-05</p>

Sammanfattning Kvinnors ekonomiska förutsättningar har förbättrats enormt de senaste decennierna, men än idag råder det skillnader i lön mellan kvinnor och män. Många tror att denna skillnad beror på att kvinnor väljer att fokusera på familjelivet då de får barn. Om det faktum att kvinnor får barn faktiskt leder till dessa löneskillnader, så innebär det inte bara att män och kvinnor har olika lön, men också att kvinnor som har barn och kvinnor som inte har barn har olika lön. Detta är studiens syfte, alltså att undersöka om en kvinnas lön påverkas negativt av att hon får barn. För att kontrollera detta jämförs lönen mellan kvinnor med barn och kvinnor utan barn. Vidare så studeras även om lönen för kvinnor med barn påverkas olika mycket beroende på hur många barn hon har. Detta formuleras till två frågeställningar; ”Finns det en genomsnittlig skillnad i lön mellan kvinnor som har barn och kvinnor som inte har barn?” och ”Finns det genomsnittliga skillnader i lön beroende på hur många barn kvinnor har?”. För att kunna besvara dessa frågeställningar har olika teoretiska perspektiv använts, nämligen humankapitalteorin samt rational choice theory. Båda dessa förklarar olika tänkbara aspekter av varför en kvinnas lön skulle påverkas negativt av att hon skaffar barn. Vidare har även tidigare forskning som beskriver “The Wage Penalty of Motherhood” använts genomgående i studien, för att ge ytterligare eventuella förklaringar till att kvinnor med barn har en lägre lön. Studien använder en kvantitativ ansats med ett sekundärt datamaterial från Levnadsnivåundersökningen år 2010. Med detta datamaterial har regressionsanalyser genomförts, för att kunna studera sambanden mellan kvinnor, barn och lön. Resultatet visar, i motsats till tidigare forskning och teorier, ett positivt samband mellan att ha barn och lön, och även ett positivt samband mellan antalet barn och lön.

Human and animal decision-making is known to violate rational expectations in a variety of contexts. Statistical structures of real-world environments may account for such seemingly irrational behavior. In a computerized experiment, 16 capuchins, 7 rhesus monkeys, and 30 humans chose between up to three options of different value. The options disappeared and became available again with different probabilities. Subjects overwhelmingly chose transitively (A>B, B>C, and A>C) in the control condition, where doing so maximized overall gain. However, most subjects also adhered to transitivity in the test condition, where it was suboptimal but led to negligible losses compared to the optimal strategy. Only a few of the capuchins were able to maximize long-term gain by violating transitivity. Adhering to rational choice principles may facilitate the formation of near-optimal decision rules when short- and long-term goals align. Such cognitive shortcuts may have evolved to preserve mental resources.

This essay is concerned with two explanations of why oppressive social orders persist. According to the first, the so-called gunman theory of oppression (GT), these social orders persist because the oppressed are afraid being punished if they participated in a revolt. According to the second, the so-called ideology theory of oppression (IT), oppression persists because the oppressed are subject to ideology. Traditionally, the former has been associated with rational choice theory, and the latter with Marxism and critical theory. Analytical philosophers have been suspicious of IT since it involves functional claims. This essay shows that it is possible to make sense of both IT and its associated functional claim within the framework of rational choice theory. Chapter one provides an overview of the discussion and a presentation of the general argument against IT. Chapter two specifies the explanandum for the two theories in more detail. The chapter concludes with a description of three real-life persistent oppressive social orders. In chapter three, the basics of rational choice theory are introduced and GT spelled out. Some problems for the theory are identified and then dealt with. It is concluded that GT does a good job at explaining the persistence of tyrannies. Chapter four argues that ideology is necessary to provide satisfactory explanations of the other two cases of oppression described in chapter two. The chapter concludes with a specification of IT where the functional claim is made explicit. Chapter five defends Gerald Cohen's account of functional explanations against a dilemma formulated by Ann Cudd. In chapter six, three mechanisms are provided that indicate how the functional claim of IT can be demystified. Chapter seven concludes by indicating a statistical method for testing IT and describing some policy implications. / EXPLANATIONS OF REPRESSION BY A MINORITY OF THE MAJORITY — A RESEARCH PROGRAM

<p>Traditional approaches to the empirical research of human action, rational choice theory dominant amongst them, have implicitly adopted philosophical pre-suppositions about human action that are untenable and in need of correction. In this project, I seek to both (a) diagnose these problems by showing that rational choice theory is insufficiently attentive to both the question of what agents are and of what kind of world they occupy, and (b) overcome these problems by offering a conception of practical reason that is more "realistic" in that it incorporates a philosophically convincing account of world and of the practical agent's relation with it. To that end, I develop a conception of praxis that is centered on the idea that practical agents act within and toward practical horizons rather than exercising a faculty of choice within stable decision spaces.</p> / Dissertation

The thesis includes two essays on asset pricing. In the first essay, "Asset Pricing in a Monetary Economy with Heterogeneous Beliefs", we shed new light on the role of monetary policy in asset pricing by focusing on the case where investors have heterogeneous expectations about future monetary policy. Under heterogeneity in beliefs, investors place bets against each other on the evolution of money supply, and as a result, the sharing of wealth in the economy evolves stochastically over time, making money non-neutral. Employing a continuous-time, general equilibrium model, we establish these fluctuations to be rich in implications, in that they majorly affect the equilibrium prices of all assets, as well as inflation. In particular, we find that the stock market volatility may be significantly increased by the heterogeneity in beliefs, a conclusion supported by our empirical analysis. The second essay is titled with " Asset Pricing and Welfare Analysis with Bounded Rational Investors". Motivated by the fact that investors have limited ability and insufficient knowledge to process information, I model investors' bounded-rational behavior in processing information and study its implications on asset pricing. Bounded rational investors perceive "correlated" information (which consists of news that is correlated with fundamentals, but provides no information on them) as "fundamental" information. This generates "bounded rational risk". Asset prices and volatilities of asset returns are derived. Specially, the equity premium and the stock volatility are raised under some conditions. I also analyze the welfare impact of bounded rationality.
