This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index. The results suggest that the market correctly prices IPOs in the long run thus upholding the Market Efficiency hypothesis. Moreover, value weighted CARs show that large IPOs are more likely to outperform smaller IPOs, however in the long run there is an unpredictable pattern.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

This study has been conducted in order to determine the existence of predictability for the Stockholm stock exchange. With this purpose the random walk theory has been raised against the theory of mean reversion in order to determine which theory is the most substantial. Data has been collected from Nasdaq OMX Nordic and furtherly been processed using the statistical software EViews. Swedish listed companies? daily share values between 2000-2014 have been analyzed using two tests; an Augmented Dickey Fuller test and a Variance Ratio test.

The aim of this study is to examine whether the two factors SMB and HML in the Fama-French Three Factor Model proxy for default risk. The study is based on companies noted on the Stockholm Stock Exchange between 2003 and 2008. These companies are used to create the factors SMB and HML, as well as a default risk factor we call RMS. In a first set of regressions, we examine the explanatory power of the original Fama-French model on a set of portfolios consisting of Swedish companies of different size and book-to-market ratio. The default risk factor RMS is then added to the original Fama-French model.

This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

In this study, the sea trout (Salmo trutta) spawning migration was studied in the river Själsöån, Gotland, to assess the main external factors determining upstream migration and seasonal changes in fish parameters. Additionally population trends were studied by examination of old data. The most important external factors for upstream migration were the air pressure, air temperature and wind direction. No significant difference was found between when males and females migrated upstream. Larger females in better condition started migration earlier than the smaller females in poorer condition.

This paper?s objective is to investigate whether Modigliani and Miller (MM) I & II proposition from 1958 with regard to capital structure, is still valid among public Swedish firms.We have chosen the 63 firms on the Stockholm Stock Exchange (OMX) that Affärsvärlden magazine?s general index (AFGX) has categorized as industrial firms. We based this selection on the assumption that these firms are relatively capital intense and have a clear focus on production and, therefore, mainly uses capital structure as a mean to finance their production and not as a means in itself.To be able to fully evaluate these firms we have calculated the current Key ratios based each firm?s annual report. To make the figures comparable across the entire population we adjusted them to each firm?s turnover.The results we have reached concur with MM?s proposition I regarding capital structures independence of the firm value.

This master thesis concerns whether Swedish non-financial listed firms act in accordance with the optimal capital structure theory and/or pecking order theory. The examined period is 1998-2004 and we discover that Swedish companies neither follow optimal capital structure theory nor pecking order theory. From our results we conclude that there exists no single point of the capital structure which is optimal. Rather it seems as if the optimal point lies in-between an interval from 0 to the industry average, where firms tend to be indifferent to their debt-ratios. Our results show that Swedish companies prefer internal financing followed by equity and as last choice debt issuance..

Previous work by researchers as Eugene F. Fama and Kenneth R. French, show that average return on stocks are related to a firms characteristics like size and book-to-market ratio. These kinds of patterns in average return is not explained by The Capital Asset Pricing Model (CAPM), and are therefore seen as anomalies. Fama and French have proposed a three-factor model, which captures patterns observed in U.S average returns associated with size and value.

The purpose of this study is to explore how teachers in Sweden and Croatia work with children that have problems like ADHD and dyslexia in school. I have chosen to compare pedagogical methods between Swedish and Croatian teachers which are used in work with children with difficulties when it comes to the education and teachers approach to these children. I have done a qualified study and have interviewed teachers in both Sweden and Croatia and one specialist in pedagogy in Croatia. I compared with these interviews information from earlier studies and literature. Results show that teachers in Sweden are of the opinion that every student who has these difficulties is different and therefore the use a variation of pedagogical strategies is crucial.

The thesis handles the principal-agency problem between shareholders and the Chief Executive Officer. The purpose of the thesis was to examine the link between CEO compensation and corporate performance measured as a change in Market to Book ratio. Data was collected from corporate annual reports between the years 2000 ? 2008 and the study covers 39 Swedish companies from the Stockholm Stock Exchange Large Cap list. To examine whether there is a link between the CEO´s compensation and firm performance, we performed a regression analysis, and no significant relation is found.

Vägar och järnvägar är viktiga transportsystem som har stort påverkan på vårt vardagliga liv. Att fortsätta utvecklingen för att skapa större förståelse för hur dessa konstruktioner påverkas av nedbrytning är viktigt för att inte skapa långlivade konstruktioner som inte uppfyller morgondagens förändrade krav. Hos konstruktioner som består av ballastmaterial beskrivs nedbrytning orsakad av yttre laster främst som förändringar på jordmassans egenskaper. Ett steg i riktningen för att bättre förstå nedbrytning är att beskriva de kornformsförändringar som uppkommer. Ett antal beskrivande storheter för kornform presenteras: soliditetcirkularitet, aspect ratio, roundness och .

The aim of this study is to learn about the nineteenth century poor relief system, how itoperated in the rural parish Kristdala during the period 1881-1890, and not least, who was thesupported person? The poor are defined as the individuals that received public poor relief, but in onechapter this definition of poverty is contrasted with a definition based upon tax exemption:inability to pay taxes. Two villages have been selected for intensive study, namely Kroxhult and Calerum, and Calerum is the smaller one. The connection between age and the poverty ratio is clear, and tobe a lodger was especially disadvantageous with respect to poverty. Further the position ofwidow was the most unfavourable among the female poor people.
