Kan företag genom sin redovisningsinformation påverka volatiliteten i aktiekursen?: en studie av sambandet mellan informationskvalitet och risk
The purpose of this paper was to examine the potential presence of a relationship between the quality of corporate financial disclosure and the volatility in stock price in the Swedish market. This was carried out by investigating the hypothesis that an accurate annual report with high information quality results in a decrease in volatility. Previous studies have been done with this approach and in some cases the above stated hypothesis was found to be true. Thus, in the absence of a perfect efficient market the level of information quality may to some extent explain the volatility in stock price. However, the result of our study gave no evidence in support of this hypothesis.
Konstitutionsutskottet och Regeringskontrollen - En studie av kontrollmaktens utövande i enkammarriksdagen 1971-2007
The purpose of this study is to examine how parliament executes its responsibility of oversight against the government. In Sweden, parliamentary oversight of the government rests with a standing committee of parliament known as the constitutional committee.Drawing on general principal-agent theory I construct a model in which members of the constitutional committee are seen as agents in double and conflicting agency assignments. This constitutes a problem for the agent. Since it is the party group in parliament that controls the fulfilment of the agents? objectives, the agent is presumed to follow the party assignment to the detriment of the parliament assignment.The model generates two hypotheses concerning they type of oversight we should expect the members of the constitutional committee to perform against the government.
International transmission of stock market movements - a Scandinavian focus -
Previous research has found an increased transmission of stock movements in Europe, partly caused by the establishment of institutions as the EU and the EMU. The purpose of this paper is to find the possible impact from the EU and the EMU concerning the evolution of international transmission of stock market movements, on four Scandinavian markets, Denmark, Finland, Norway and Sweden. The research is based on primary data, existing theories and earlier studies regarding international transmission of stock market movements. The examined method is a VAR (Vector autoregressive model) including a 10x1 vector of variables. Furthermore the tests considered are correlation, granger-causality, variance decomposition and impulse response.

Har storleken någon betydelse? : En studie av den svenska aktiemarknadens reaktion på varsel om uppsägning av personal
Background: The reasons why this study is conducted is because of the latest recession in the global economy. The current recession has made a lot of companies more aware of its cost, and in order to fit the new harsher economic climate the companies has to be more cost efficient. In order to do so many companies choose to reduce their amount of employees. When this happens in a recession, most of the layoffs are an effect of reactive causes, such as lower incoming orders, and fewer customers. This leads to a problem for the companies that don?t know how these kinds of layoffs will affect the value of the company?s stock.
Handelsstopp på Stockholmsbörsen. Innebär handelsstoppen på Stockholmsbörsen en trygg handel och en effektiv marknad
This paper examines if trading suspensions on Nasdaq OMX Nordic - Stockholm work as a contributing factor in creating a secure trading. This has been made through an event study and examination of abnormal returns. Our results for plus tick suspensions indicate that suspensions fulfill their purpose in creating a more secure trading since the trend of abnormal return we observe prior to a suspension is disrupted. Thus, the suspension is warranted. The conclusion is that the market cannot be completely safe; as the law and practice is structured today an abnormal return is inevitable.

Omvänd aktiesplit : överlevnad eller kosmetik
The shareholder is supposed to be indifferent if one share costs 100 SEK, or 10 shares cost 10 SEK each. In an efficient market, shares should be valued directly to new expectations as a result of the announcement of the reverse split. We investigate whether abnormal returns incur surrounding reverse split and if owner structure change.One reason for the reverse share split is that most companies have plans to imple-ment other company?s specific events in order to survive rather than to change the price range to a more attractive level. We found a negative return in the ex-day at 8,1 per cent.
Att få vara med och skriva manus : Att motverka traditionella könsroller genom dramapedagogik i förskolan
The purpose of this thesis is to study how preschool teachers can reach the goal of the swedish educational plan to prevent traditional gender roles for children ages 3-6 through drama in education.This is answered by four hypothesis based on Judith Butler's queer theory, George Herbert Mead's social psychological theory and Gavin Bolton and Dotothy Heathcotes drama pedagogical theories. The hypotheses are tested against four teachers' examples of their work.The hypotheses areHypothesis 1: By using the expert's mantle and active observation in teacher-in-role indrama educational exercises, we can see how the children internalize the heterosexualmatrix and the outline of the internalized other.Hypothesis 2: By using the "mistakes" that occur when children repeat performativeacts that do not fit with the heterosexual matrix, these other possible behaviors can bestrengthenedHypothesis 3: Through drama exercises that are not normative teachers can widen theheterosexual matrixHypothesis 4: Through drama pedagogical methods like teacher-in-role teachers canprovide possibilities of other performative acts and the creation of a more tolerantinternalized other.The analysis show that the respondents work within all these hypotheses in different ways and thathypotheses 2 is the one with the weakest support in the interwievs. The examples are also weakregarding the use of Boltons drama pedagogical methods, but that there are a number of othermethods in use.Some of the conclusions are that more theoretical knowledge in the preschool drama pedagogics tocounteract traditional gender roles and patterns, as well as the drama of educational theory need tobe linked to queer and social psychology research. There is also no monitoring of the long term effects of the work..
