Fondförvaltares finansiella prestationer : sett utifrån demografiska faktorer samt gruppaspekter

Månsson, Carl, Pllana, Arlinda January 2017 (has links)
Intresset för fondsparformen har ökat de senaste åren och med tanke på att åtta av tio svenskar sparar i fonder är det viktigt att undersöka vad det är som påverkar hur en fond presterar utifrån vem som förvaltar fonden.    Syftet med studien är att bidra med ökad kunskap kring vad det är som påverkar en fondförvaltares prestationer. Studien avser först att undersöka den enskilda fondförvaltarens prestation i form av riskjusterad avkastning utifrån de demografiska aspekterna. Därefter undersöks om grupper presterar bättre eller sämre riskjusterad avkastning än enskild individer och slutligen undersökes om gruppers diversitet, utifrån de demografiska aspekterna, påverkar fondens prestation också mätt i riskjusterad avkastning.   Studien utgår från ett positivistiskt synsätt och en forskningsstrategi med en deduktiv ansats. Metodvalet karaktäriseras av ett kvantitativt tillvägagångssätt där empirin grundar sig på icke-indexfonder i Morningstars kategorisering Sverigefonder.   Studiens övergripande slutsatser är att de olika demografiska aspekterna har olika påverkan på den riskjusterade avkastningen. Grupper presterar generellt sämre än enskilda individer och ju mer diversifierad gruppen är desto sämre blir också resultatet. / The interest of saving in funds has risen in recent years. Since eight of ten Swedes have got savings in funds it’s important to investigate what affects the funds’ performance, based on who manages the fund.   The purpose of the study is to contribute with increased knowledge about what affects the performance of fund managers. The focus of the study is firstly on different demographic aspects and how they affect the risk-adjusted returns. Secondly the study examines whether group performances are superior to individuals. Lastly the study also examines whether more diverse groups perform better than less diverse groups.   The study is based on a positivistic approach and a research strategy with a deductive approach. The method selection is characterized by a quantitative approach where data is based on non-index funds in the Morningstar categorization of Sverigefonder.   The overall conclusions of the study is that different demographical aspects have different effects on the risk-adjusted returns. Groups generally perform worse than individuals and the study also concludes that the more diversified the group gets, the worse the results will be.

The Effects of Ego Depletion and Emotional Intelligence on Risk-Taking

Bishop, Travis 01 January 2017 (has links)
Ego depletion theory postulates that the ability to exert self-control depends upon the availability of a limited mental resource. In this experiment, we investigated the effects of ego depletion on risky decision-making. We also examined the moderating effect emotional intelligence may have on this relationship. First, participants completed a trait emotional intelligence questionnaire and a self-control task. This was followed by a mood questionnaire and a series of risky-decision scenarios. Results showed (1) participants who were depleted made more risky decisions than non-depleted participants, (2) no differences in perceived task effort between groups, (3) no evidence of a moderating effect for emotional intelligence and (4) depleted participants were more aroused and their moods were more negative than non-depleted participants. Taken together, these results imply that ego depletion enhances the inclination to take risks and that decisions involving risks should not be made under these conditions.

Privatpersoners finansiella risktolerans vid aktieinvestering : En studie om vilka aspekter som påverkar / Individuals’ Financial risk tolerance When investing in Stocks : A study of affecting aspects

Colliander Samuelsson, David, Ivarsson, Henrik January 2017 (has links)
The economic development in Sweden in recent years has led to increased financial savings in Swedish households. Financial savings have mostly increased on bank accounts with low interest rates, since private individuals generally have a more cautious position on stocks and stock trading. The reason for this passive position is believed to be due to the fact that decisions that benefit most economically often challenge the feeling of being in control. At the same time, cautious position that a particular individual possess is affected by the risk-tolerance. As a consequence, the risk tolerance of private individuals affects the investment decision and hence the development of the stock market. Savings and investment are two important factors that affect a nation's economic growth, which makes it important to study underlying factors to what affects an individual when making a financial decision. When talking about risk tolerance in everyday life, previous research has revealed that there are four different aspects that affect this complex concept, namely the economic aspect, physical aspect, social aspect and ethical aspect. As investment decisions are affected by financial risk tolerance and the four aspects in turn, affect risk tolerance, the issue becomes how these aspects affect a private investor's financial risk tolerance when investing in stocks. The purpose of this study has been to explain the four aspects of a person’s risk tolerance when investing in stocks. The study has been conducted using a quantitative method and deductive approach. The selection group that the study turned to is Swedish stock investors and the data collection has been done by a survey that was answered by 232 people. The underlying factors for the four aspects tested in the study are income, gender, age, education, marital status and ethical character. The study shows that all four aspects together have a combined impact on private individuals' financial risk tolerance. The study has also shown that all the four aspects, each one separately, are linked to financial risk tolerance, by the underlying factors, income level, gender, marital status and ethical character. / De senaste årens ekonomiska utveckling i Sverige har lett till ett ökat finansiellt sparande i de svenska hushållen. Detta sparande har mestadels ökat på bankkonton med låga räntor då privatpersoner i allmänhet har ett mer försiktigt ställningstagande till aktie och börshandel. Anledningen till detta passiva ställningstagande tros bero på att beslut som gynnar mest ekonomiskt ofta utmanar känslan av att ha kontroll. Samtidigt påverkas ställningstagandet av den risktoleransnivå som en viss individ besitter. Följden av detta blir att privatpersoners risktolerans påverkar investeringsbeslutet och därmed även utvecklingen av aktiemarknaden. Sparande och investering är två viktiga faktorer som påverkar en nations ekonomiska tillväxt vilket gör det viktigt att studera bakomliggande faktorer till vad som påverkar en privatperson när ett finansiellt beslut ska tas. När det pratas om risktolerans i vardagslivet har tidigare forskning delgett att det finns fyra olika aspekter som påverkar detta komplexa begrepp, nämligen den ekonomiska aspekten, fysiska aspekten, sociala aspekten och etiska aspekten. Då investeringsbeslut påverkas av den finansiella risktoleransen och risktoleransen i sin tur påverkas av de fyra aspekterna blir problemfrågan hur dessa aspekter påverkar en privatpersons finansiella risktolerans vid investering i aktier.  Syftet med denna studie har varit att förklara de fyra aspekterna för privatpersoners finansiella risktolerans vid aktieinvestering. Studien har genomförts med hjälp av en kvantitativ metod och deduktiv ansats. Den urvalsgrupp som studien vänt sig till är svenska aktieinvesterare och datainsamlingen har gjorts med hjälp av en enkätundersökning som besvarats av 232 personer.  De bakomliggande faktorerna för de fyra aspekterna som har testats i studien är inkomst, kön, ålder, utbildning, civilstånd och etisk karaktär. Studien visar att alla fyra aspekter tillsammans har sammantagen påverkan på privatpersoners finansiella risktolerans. Studien har även visat att alla de fyra aspekterna har en koppling till den finansiella risktoleransen, var och en för sig, genom de underliggande faktorerna inkomstnivå, kön, civilstånd och etisk karaktär.

Neuroekonomie / Neuroeconomics

Houdek, Petr January 2006 (has links)
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.

A Cross-sectional and Longitudinal Study of Adolescents and Religion: Views of Risk and Resiliency

Miesse, Colette Ann 08 1900 (has links)
The research literature within the past decade has documented the importance of religiosity and spirituality in helping many adults around the world cope with major life stressors and events. Still, the role of religiosity and spirituality in adolescence is not well-known as research during this developmental period has been limited by sample size, homogeneity of samples, ethnic restrictions, and use of scales with few items. The goal of the current study is to identify and understand adolescent levels of religiousness and spirituality, as well as their roles on later social, emotional, and behavioral outcomes. The current study relied upon data from the National Longitudinal Study of Adolescent Health and utilized confirmatory factor analysis and structural equation modeling in order to generate models of the relationships between the various latent variables. The religiosity and spirituality factors in the current study adequately measure religious perceptions and practices of adolescents over time. These constructs also play a role in later emotional well-being and self-esteem. Analyses also found adequate predictive abilities in the other model factors of delinquency, psychological well-being, self-esteem, and the social support. It is concluded from this study that religiosity and spirituality are not interchangeable constructs, and that more robust measures of both factors yield richer results. It is recommended that more comprehensive scales of religiosity and spirituality be developed and investigated in the future.

Late adolescents' parental, peer, and romantic attachments as they relate to affect regulation and risky behaviors.

Ingle, Sarah J. 08 1900 (has links)
The current study examined the relationships among attachment styles to parent, peer, and romantic partner, ability to regulate emotion, as well as engagement in sexual behaviors and substance use. Attachment theory and previous research suggests that an individual learns how to manage emotions through the modeling of appropriate techniques and a stable sense of self-worth. These two aspects develop through a secure attachment bond with an important figure. When an individual does not have a secure attachment bond in which to practice adaptive affect regulation strategies, he/she may attempt to manage emotions through external means, such as sexual behaviors or substance use. Overall, results supported these associations, with some notable exceptions. Across attachment sources a secure attachment style was related to lower levels of psychological distress and less engagement in substance use. In contrast to the findings from earlier studies, affect regulation did not mediate the relationship between attachment and substance use, and engagement in sexual behaviors was not significantly related to either attachment style or affect regulation.

L'instabilité sociale et la prise de risques dans le jeu de hasard, les droites parallèles d'un labyrinthe comportemental

Glorieux, Gérard 17 November 2010 (has links)
L’image du plaisir ou de l’évasion que révèle jeu et les prises de risques, laissent rarement la place à une vision immédiate et simple de la réalité. Le danger de l’assuétude, et l’attrait des prises de risques, guettent le joueur dans l’élan et la ferveur de jeux anodins qui procurent le plus grand plaisir, mais ces dangers sont difficilement perceptibles et quantifiables. Tant que ce plaisir est contrôlable, et reste le libre choix de celui qui s’y adonne, le jeu n’est pas une attitude marginale, pas plus qu’un quelqu’autre divertissement ;ce n’est que la pratique excessive de son activité, c’est-à-dire son comportement, qui peut devenir marginale <p>Nous croyons que les prises de risques dans les activités ludiques ne sont pas plus déviantes, répréhensibles ou particulières que celles d’un simple quotidien mais qu’elles sont simplement situées dans un environnement différent. Au terme de notre travail théorique, nous pouvons dire qu’en ce qui concerne la prise de risques, que l’expérience favorise l’acuité d’évaluation du gradient risque. D’autre part, certains individus sont plus prédisposés à prendre d’initiative des risques, alors que d’autres restent soit timorés ou y sont mêmes averses. Cette recherche de sensations stimulantes que certains aiment trouver d’une part, et la réserve des autres ne constituent pas une dichotomie en classes significatives qui permettraient de dresser un profil type du preneur, et non preneur, de risques. Chacun réagit en fonction de son anamnèse particulière, de son état émotionnel du moment, et de ses limitations cognitives d’analyse de la situation. <p>Par ailleurs, l’illusion de contrôle de la situation accentue la prise de risques. Une idée générale veut que chacun croit faire de meilleurs choix dans ses risques préférentiels, que le voisin. Cette position est erronée, les choix personnels de tout un chacun n’étant pas meilleurs que ceux du prochain mais ils correspondent mieux à celui qui les a posés. La prise de risques est un changement de mode opératoire de nos comportements obligataires. En l’exerçant, nous tentons de surpasser ce que nous croyons être les limites de l’instant ;dépassement de soi illusoire qui fait immédiatement découvrir de nouvelles frontières restrictives de notre potens.<p> <p>Par ailleurs, tout comme nous avons énoncé qu’il y avait deux formes de jeux de hasard (égocentré et altruiste), il y a deux approches à considérer dans la prise de risques. Les prises de risques, tant sociale que ludique, qui relèvent des prises de risques en tant que jeu d’affirmation et de recherche des limites personnelles, et celles spécifiques aux jeux de hasard qui outre le justificatif précédent, considèrent de plus, le but de la prise de risques ludiques comme le véhicule d’un chemin substitutif aux revenus du labeur. Il y a aussi deux formes d’instabilité :l’instabilité sociale qui confine les individus dans une situation d’état communautaire non associatif et précaire, et l’instabilité émotionnelle qui réduit le ressenti personnel au sentiment d’injustice. Quelle que soit la cause de l’état d’instabilité, qu’elle soit imputable aux manquements de l’individu, ou le résultat du hasard, cet état ressemble souvent à un labyrinthe du désespoir dont l’accès à la sortie impose une énergie et des opportunités qui sont rarement à portée des candidats à un renouveau. Repartir exige de parcourir successivement deux chemins :celui du retour à l’état initial d’équilibre puis celui du nouveau départ vers des objectifs futurs. / Doctorat en Sciences politiques et sociales / info:eu-repo/semantics/nonPublished

Strategiskt risktagande hos bolag på Stockholmsbörsen : En studie om hur sammansättningen av ledningsgrupp och styrelse påverkar det strategiska risktagandet i svenska börsbolag / Strategic risk-taking for companies on the Stockholm Stock Exchange : A study on how the composition of the management team and the board affects the strategic risk-taking in Swedish listed companies

Kembring, Linda, Tillmar, Lovisa January 2021 (has links)
Bakgrund: Kvinnors väg till toppositioner inom näringslivet kantas av fler hinder än deras manliga motsvarigheter. En anledning kan vara de antaganden som finns kring kvinnors riskundvikande. Liknande antaganden finns även när det kommer till ålder och ämbetstid i beslutsfattande positioner. Det strategiska risktagandet är ett resultat av det strategiska beslutsfattande styrelser och ledningsgrupper utför, varpå intresse finns i att se om samband råder mellan variablerna eller om antagandena är felaktiga. Syfte: Studiens syfte är att få ökad förståelse för relationen mellan ledningsgruppens och styrelsens sammansättning och bolags strategiska risktagande. Metod: Det är en kvantitativ metod som appliceras på studien med en deduktiv ansats. Teorierna som behandlas är Prospect theory, Social identity approach och Upper echelons. Datainsamlingen utgår från nyckeltal från respektive bolags årsredovisningar och Infotorg Företag. Resultat: Alla hypoteser förkastas och slutsatsen blir därför att kvinnor, ålder och styrelsens respektive ledningsgruppens ämbetstid inte har något specifikt inflytande på det strategiskt risktagande då det inte hittades några samband för detta. / Background: Women's path to top positions in organisations is lined with more obstacles than their male counterparts. One reason may be the assumptions that exist about women's risk avoidance. Similar assumptions also exist when it comes to age and tenure in decision-making positions. The strategic risk-taking is a result of the strategic decision-making boards and top management teams carry out, whereupon there is interest in seeing if there is a connection between the variables or if the assumptions are false. Purpose: The study aims to gain an increased understanding of the relationship between the composition of the board of directors and the top management team, and companies' strategic risk-taking. Method: It is a quantitative method that is applied to the study with a deductive approach. The theories covered are Prospect theory, Social identity approach and Upper echelons. The data collection is based on key figures from each company's annual reports and Infotorg Företag. Conclusion: All hypotheses are rejected and the conclusion is therefore that women, age and the term of office of the board and management team have no specific influence on the strategic risk-taking as no connection was found for this.

The Relationship Between Hope, Core Self-Evaluations, Emotional Well-Being, Sexual Risk Taking, Substance Use, and Academic Performance in Freshman University Students

Griggs, Stephanie 14 April 2017 (has links)
Objective: To examine the relationship between hope, core self-evaluations, physical function, emotional well-being, health risk behaviors, and academic performance in freshman enrolled in their first year of college. Participants: Freshman (N = 495) attending a large public university in the Northeast completed an online survey between February 1 to February 13, 2017. Methods: Cross sectional descriptive survey. Linear regression, path analysis, and structural equation modeling procedures were performed. Results: Core self-evaluations mediated the relationship between hope and emotional well-being and academic performance. Contrary to the hypotheses, higher hope predicted more sexual risk taking behaviors and alcohol use. Conclusions: Core self-evaluations is an important component of hope theory. Hope Theory is useful for predicting emotional well-being, and academic performance, but not as useful for predicting drug use, alcohol use, and sexual risk taking. Hope and core self evaluations interventions are needed to improve academic performance and emotional well-being in university freshman.
