Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data

A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..

Jämförelsestudie för tre olika metoder att beräkna genomstansning i betong : Skillnader i genomstansningskapacitet för metoderna i BBK04, EK2 och BHB

Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.

Tvärsnittskorrelation; Svenska aktiebranscher 1997-2007

I denna uppsats behandlas ett nytt sätt att beräkna korrelationen mellan olika tillgångar. Me­toden, tvärsnittskorrelationen, har framarbetats av Bruno Solnik och Jacques Roulet som be­skriver den i artikeln Dispersion as Cross-sectional Correlation. Vårt syfte är att med hjälp av detta nya sätt beräkna korrelationen över en tio års period på den svenska aktiemarknaden och se om vi kan hitta tendenser i korrelationens utveckling. Korrelationens tendens har tolkats genom trendlinjer och determinationskoefficienter. De re­sultat vi får fram tyder på en ökning i korrelationsnivå inom de flesta av våra observerade sektorer på den svenska aktiemarknaden..

Konstruktion av sök/räddningsrobot

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

Företagshybridkapital i Sverige: Möjligheten att få både skattesköld och klassning som eget kapital enligt svensk rätt

The new Swedish Companies Act allows Swedish companies to issue two instruments that were previously prohibited: mandatory convertibles and participating debentures. The aim of the thesis is to conduct a cross sectional study of Swedish corporate hybrid securities, especially in the light of the new Companies Act. The cross sectional study also includes areas such as credit rating, accounting and tax. The thesis concludes that it is possible, under Swedish law, to issue corporate hybrid securities that qualify for both high equity credit and tax deductible interest payments. The use of certain hybrid provisions are, however, restrained by Swedish company law.

How Does Board Structure Influence CEO Compensation? - Evidence from Sweden

The purpose of the study is to investigate how board structure influences CEO compensation for companies listed on the Stockholm Stock Exchange in 2004. The theoretical frame of reference is based upon the corporate governance theory, the principal-agent theory and previous empirical research in the area. A cross sectional regression analysis is used, where a number of control variables are included and significance tests are conducted. The study is based on information regarding CEO compensation, and possible factors affecting the compensation, from 267 companies listed on the Stockholm Stock Exchange A- and O-list in the year 2004. We find that the board structure has no significant effect on the CEO compensation.

Meningen med aktiekapitalet : ? Är aktiekapitalet en gammal förlegad tradition som har bevarats?

Introduction: There was a reduction in Sweden of the share capital in 2010, in which the share capital was reduced from 100 000 SEK to 50 000 SEK. The reason behind the reduction of the share capital was to enable more people to start limited liability companies in Sweden. Meanwhile in Europe, they questioned the function of the share capital, and as a result of this discussion a number of European countries have abolished the requirement for the share capital in limited liability companies.Purpose: The purpose of this study is to investigate what meaning the share capital has to entrepreneurs based on their own businesses, and to see what function the share capital have for the creditors.Problem: What are the meaning of the share capital for today´s entrepreneurs and its creditors?Methodology: The study is based on a qualitative research method in which a cross-sectional study was done with four small limited liability companies and four creditors.Conclusions: The share capital functions and meaning has lost its intended meaning as creditor protection and the help to facilitate the raising of capital. The share capitals intention has to some extent been eroded.

FYSISK AKTIVITET PÅ ÄLDRE DAR : En kvantitativ studie om motiv till fysisk aktivitet bland människor över 60 år

The average life expectancy and the proportion of elderly are increasing globally and inSweden, causing challenges for the society. Physical activity has proven to bring a number ofpositive benefits in older people, making the promotion of physical activity an important partof healthy aging attempts. The degree of physical activity in Sweden?s elderly population isgreater than in previous generations, making this group a positive exception from a widerperspective. A cross sectional study was made in order to investigate which motives tophysical activity that was considered most important among people above 60.

Arbetslöshet bland utrikes födda på den svenska arbetsmarknaden : En empirisk analys av vilka kommunala faktorer som kan påverka den höga arbetslösheten bland utrikesfödda

Unemployment amongst Swedish citizens is higher within the group which falls under the designation foreign-born. The aim of this thesis is to examine which municipal factors that can explain the differences in unemployment amongst foreign-born relative to native born.The empirical models are examined with both Cross-Sectional Data for the year of 2010 and panel data for the years of 2002-2012. The examination is implemented through a linear regression analysis of the type Ordinary Least Squares (OLS) and Fixed Effect regressions. A theory section will be presented where the theory on Non-Accelerating Inflation Rate (NAIRU), theories on discrimination and country-specific human capital are illustrated.The result from the Cross-Sectional Data shows that the amount of foreign-born, the level of foreign-born immigrated from Nordic countries have a significant negative effect on unemployment amongst foreign-born. The general unemployment shows a significant positive effect on the unemployment amongst foreign-born.

The Determinants and Impacts of Executive Stock Options

The thesis main objective is to establish the determinants for granting executive stock options and to examine their impact on performance for firms listed on OMXS30. The analysis is based on accounting data gathered from annual reports and Thomson Datastream. The empirical results display that firms grant stock options to mitigate the principal-agent problem. Furthermore, risk proves to be positively significant with executive stock options, implying that either executives increase the level of risk after being granted stock options or influence the decision of the remuneration towards stock options when the firm increase the level of risk, in purpose to boost the expected value of their options. No relation between executive stock options and firm performance could be established..

The Value of Relationships in a Chinese-Western Business-to-Business Context: An Investigation on Relationship Bonds, Adaptation, Trust and Commitment

The purpose of this study is to improve the understanding of the dynamics behind Chinese-Western buyer-supplier relationships. The study takes on a partially inductive approach by commencing with exploratory in-depth interviews. The main body of the study consists of a cross-sectional survey. Data has been collected through an on-line questionnaire. The theoretical review consists of industrial relationships with specific accounts on the role of adaptation, trust and commitment; a stream of literature in cross-cultural relationships deriving from Hofstede?s culturalist legacy with specific reference to Chinese-Western relationships, including studies on relationship bonding, and the role of guanxi.

Den nationella värdegrunden inom äldreomsorgen:några enhetschefers intryck

The aim of this text is to study how sectional managers in the care of the elderly work so as to promote basic human values. Semi-structured interviews generated qualitative data from five sectional managers. A hermeneutical approach was applied for interpreting the interviews. The result shows that the respondents are conscious of the fact that it takes a lot of long term work before a change in current procedures will happen. Also, the common everyday principles of work and basic values will continue to be part of the care of the elderly.

Vad påverkar HIV i Sydafrika? : En teoretisk och empirisk analys av Sydafrikas provinser 2008

What affects Hiv in South Africa's different provinces? This thesis examines if education, unemployment rate, GDP per capita, and the literacy rate has any relationship with the Hiv prevalence. This is analyzed using theory and data in the form of a simple microeconomic model and an econometric regression analysis based on cross sectional data of the provinces of South Africa. The regression analysis shows that unemployment rate and education have significant effects of the Hiv prevalence in South Africa. The microeconomic model in the thesis indicates that when education is higher, individuals are more aware that the probability of being infected by Hiv is higher when the Hiv prevalence is high.
