Purpose: To examine how video-game releases affect the share price, and if video-game reviews have any impact on the share price of gaming corporations. Method: A quantitative deductive research approach is applied with event study methodology used as basis. The investigated companies were the five largest gaming companies listed on the U.S. NASDAQ exchange. A total of 29 video-game launches and 85 reviews where examined.  Theory: The study is based on The Efficient Market Hypothesis, Agent Theory, Public Relations Theory, Nextopia and previous research.Results: The result contains 114 observations in five companies.

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.

This study aims to measure the effect of accounting conservatism and to identify thebusiness activities causing firms to undervalue owners? equity. To estimateaccounting conservatism, we have followed the hypothesis that no firm over time cangenerate a return greater than its cost of equity, i.e. CAPM. Thus, if a firm in factgenerates an excess return over time, we assume that the excess return is an estimateof accounting conservatism within that firm.The hypothesis originates from the corporate valuation model ?Economic ValueAdded®? which tries to adjust for accounting bias.

Syfte: Syftet med denna undersökning är att göra en komparativ studie mellan Sverige-och global aktiefonder för att vidare analysera vilka aktiefonder som ger högst avkastning.Metod: Uppsatsen bygger på en statistisk analys vilket sekundärdata ligger till grund för våra beräkningar. Genom tillämpning av kvantifierbar hård data där bland annat historiska aktiekurser ingår, så har en kvantitativ studie använts. Befintliga teorier och modeller har tillämpats.Slutsats: Studien visar i stort sett att högre risk ger en högre avkastning. Under period 1 presterade Latin Amerika fonderna bäst varefter Sverige fonder presterade bättre under period 2. Dessa marknader kan vara väldigt oberoende av varandra och tenderar därmed inte att följa varandras kursutveckingen.

The aim of this study is to examine and analyze how management control mechanisms evolve within an organization when a requirement of return on equity is imposed, as well as why the mechanisms evolve the way they do. A case study was performed on Samhall, a Swedish state-owned company, which has the aim to help people with disabilities develop by providing meaningful work. The framework provided by Samuelsson, defining five means of control in organizations was used to structure the study. Further, theories within New Public Management have been used to provide the reader with a proper background to the research area. Theories from the institutional field of organizational research have also been used to provide further depth to our analysis.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

A district heating plant has the advantage that it can take advantage of the waste heat from industries and use of cheap fuels to produce heat. But for the long term is competitive requires that energy is also saved in district heating plants. One way to save energy in a district heating system is to increasing cooling to the return temperature. This leads to less power needed to drive the distribution pumps,  and that more energy could be extracted from the same amount of fuel by an improved flue gas condensation.In Karlskoga the return temperature into the district heating plant is high. They would therefore reduce the return temperature in order to extract more energy from the flue gases.

Intense competition among companies and luck or unavailability of certain resources in country of company?s origin force last to cross the borders, and start to hunt for new markets and cheaper inputs. However, by investing abroad the company is not only facing and dealing with cultural differences and new regulatory framework, but also becomes dependent on decisions and actions of different and to large extend unknown government. Moreover, the majority of the investments? flows are directed to developing countries, where power and capabilities of state authorities are considered to be more extensive than in countries of developed economies.

The purpose of this study is to examine what motivates people to help others at risk to themselves. The focus is on international aid workers, which in their work put themselves in situations of risk. Earlier research shows that international aid work involves risks such as infectious diseases, violence, death threats, assaults, constant insecurity and risk to be traumatized etc. There is not much research done on what motivates to help others in spite of risks, hence we find this an interesting area. We have interviewed six respondents about the content and character of their motivation and factors that are important for the maintenance and development of this motivation.

This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.

Background: Within real estate companies assets according to IFRS/ IAS 40 should be valued at fair value, to compare with previous valuation criteria according to which real estate should valued at cost. Two models can be used within IAS 40, these are value at cost and fair value. When valued at cost the real estate value in the balance sheet should be specified at cost. The method chosen by the company should be used for all real estate within the company except for the premises used by the company. Purpose: The purpose of the study is to analyse and evaluate how real estate companies experienced the problems that arose when converting to IAS 40, and to analyse the effects on the companies key ratios as a result of the change of accounting method.

Question:"Does the market possess perfect information as the efficient market hypothesis says?""Is there any significant relationship between the abnormal stock return on the ex ? day and the dividend?" Purpose: The purpose of this study is to enlighten and find understanding about stock return versus dividend on the ex ? day and try to figure out if abnormal returns occur on the portfolio during dividends.Methodology:The study was based in a quantitative nature and was derived with an event study and a hypothesis testing. The authors investigated the thirty most traded shares on the Stockholm stock exchange during a period of five years (2005 ? 2009). They were analyzed during a total of nine days; the estimation window was set to sixty days.

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.
