Tranchering av Collateralized Debt Obligations med en portfölj av simulerade tillgångar

This thesis gives an introduction to securitization in general and the tranching of collateralized debt obligations in particular. It does this by using a firm-value model to simulate the underlying portfolio via monte-carlo simulations.The simulations in turn give a loss-distribution from which the various tranchings of the CDO?s are derived. To get an understanding of the influence of different variables involved in the tranching the simulations are repeated several times where the portfolio variables are changed to generate different tranchings. This to give a understanding of the influence different variables have on the tranching and consequently risks involved in CDO?s in particular but also general risks and problems of securitizations..

Prisskillnader mellan privata och publika bolag : En studie om illikviditetsrabatten och dess varierande storlek

The main objective of this study is to divide a number of colorectal cancer cases into subgroups based on their molecular features using cluster analysis. The data used is supplied by a research group at Pathology, the Department of Medical Biosciences, Umeå University, and consists, after some preparation, of 455 observations which is a larger data set than many similar studies. The molecular variables that the clustering is based on are CIMP (CpG Island Methylator Phenotype), MSI (Micro Satellite Instability), BRAF- and KRAS-mutations. These are categorical variables and consequently the clustering method used is PAM (Partitioning Around Medoids) which is particularly useful with data on diverse variable level. The final analysis results in four subgroups that are represented by different combinations of attributes on the aforementioned variables.

Effektiv sökning med Google: en jämförelse i återvinningseffektivitet mellan enkel och avancerad sökning

The purpose with this essay is to evaluate the retrieval performance between Googles basic search and the advanced search functions. A secondary purpose is to evaluate the differences between the binary relevance scale and a 4- point scale. The basic search is defined as a search with two terms combined with the Boolean operator AND. The advanced search is based on search functions that are adequate to compare to the basic search. They are categorized as AND-searches, OR-searches, AND and OR-searches, exact phrase, and depending on where the terms occur on the page.

Wheat : an analysis of variables determining the Swedish price of wheat

Increasing volatility and less political intervention from the CAP in the market price of wheat is making it more difficult than in the past for Swedish farmers to determine the price at which they should sell their wheat. In the past, the Swedish farmer-owned company Lantmännen has traditionally set a guideline price for Swedish wheat every year to which farmers could adapt, but ceased doing so last year. Therefore this study sought to identify the parameters on which the price of wheat is dependent on by using a reduced form model. The perspective adopted was that of farmers. The model proved able to identify the main factors determining the annual price fluctuations in wheat, with all variables included having an impact on the wheat price, except export quantity in the previous year.

Staten och socionomen. En kvantitativ studie av social bakgrund och välfärdspolitiska attitydmönster bland blivande socialarbetare.

The North-American sociologist Michael Lipsky has characterized social workers as street-level bureaucrats with a substantial discretion in the relationship between the welfare state and its citizens. Within Lipsky´s theoretical framework social workers appear as a powerful group that socializes the citizens to uphold certain expectations towards the welfare state and its (re)distributional programs. From this point of view, it is important to learn more about social workers and the attitudes they express towards the welfare state. The aim of this study is to analyze how the welfare-political attitudes of future social workers are affected by their social background (e.g. class background and ancestral homeland).

Utrikespolitik och krig : En fallstudie om USA:s invasion av Irak utifrån neoklassisk realism

In this essay i argue that there are three different variables that may be able to control the outcome of certain foreign policy choices. These three variables are External Threats, government division and public opinion. The Essay also tries to identify former president Bush motives behind the 2003 Iraqi War. It is partly argued that the three variables had a certain amount of influence on Bush decision making process. But the main focus lies on the motives behind the attack.

En undersökning om fallolyckor med gångtrafikanter

The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.

Vilka möjliga faktorer ligger bakom individernas varierande pensionsålder?

Fewer and fewer people from the age of 60 and upward are still in the working life according to a working survey from Central Bureau of Statistics. Only one of twenty can consider retiring after an age of 65. According to another survey that National Insurance Administration put through year 2000, just about 40 % of the working population desires to finish working before an age of 65. This trend towards lower seceding age seems to continue. There are number of factors that seem for lower retirement age and others for a higher retirement age that we prove in our study.

Entreprenörers levnadsstandard: en fråga om personlighet : Kvantitativ undersökning av den materiella levnadsstandarden hos egenföretagare i Sverige

Earlier quantitative entrepreneurial studies with a focus on poverty rate has centred their arguments and analyses entirely on income differences which has resulted in a high poverty rate among self-employed. Their results shows that variables such as age, gender, hours of labour and structure of the household significantly affect the poverty rate among self-employed. In this study we aim the focus on material living standards instead of income differences, thus using a more representative approach while studying entrepreneurial poverty. The purpose of the study was to examine how personality traits (big five) affect the material living standards among the self-employed in Sweden, using a group of employed as a control group. Variables earlier known to affect the poverty risk among self-employed where used as control variables together with education and household income.

Personal i börsbolagens hållbarhetsredovisning : en undersökning om hur upplysningar förklaras

Background and Introduction: Environmental report drew attention in the 1980s when the Va?rldskommissionen fo?r miljo? och utveckling received a mandate from the FN to investigate the relationship between economic development and environmental degradation. In connection with this, although sustainability a new item for many businesses. But to say exactly what sustainability is all about is very difficult. In 1996 the then Government Redovisningskommissionen a study on the introduction of an amendment to the Annual Accounts Act, which would force companies to report on environmental issues in their annual or consolidated accounts.

Högriskfonder kontra aktieindex : En studie av makrovariablers påverkan på olika fondalternativ

Abstract  Title: High-Risk Funds vs. Mutual- Index FundsA study of macro -variables influence on different funds choice Level: Final assignment for Bachelor Degree in Business Administration Author: Moses Yokie & Bo Lemar Supervisor: Ogi Chun & Cheick Wagué Date: 2011-05-25 Aim: The purpose with this thesis is to compare two different types of mutual-index fond and a high-risk fund in relation to the macro variables. The purpose also includes an investigation about if an investor will receives a higher return on high-risk fund than on mutual-index fund in a 10 years period.Method: A quantitative method has been use in this study, where the information has been received from Morningstar. Microsoft Excel has been used to process the collected data in order to calculate the expected return and the risk measures. The result is presented in graphs and tables on the empirical capital, in order to analyse and compare it with the theories and the selected macro- variables to see if there will be any correlation. Conclusion: This research shows that there is no possibility that the macro-variable factors can benefit an investment on high-risk fund or on mutual-index fund in the short run.

Kortsiktighet i näringslivet : En studie om förhållandet mellan VD, styrelsen, ersättning och avkastning

This study test the short-termism of companies listed on the market OMX Stockholm 30. We will use a deductive point of view where the purpose of this study is to investigate whether corporate short-term returns can be explained by the independent variables related to corporate governance and compensation practices. This is to investigate whether there is an intentional action on raising the short-term return in order to achieve a higher CEO compensation. In the study, theories dealing with corporate governance and agency theory have resulted in two hypotheses. Basic Hypothesis H1 is: if short-termism of Swedish industry due to the company's short-term returns can be explained by the independent variables related to the company's management and compensation. This hypothesis could not be verified through the quantitative study. Alternative Hypothesis H2 is: the compensation of a CEO can be explained by the independent variables related to company performance and size.
