This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

This bachelor?s thesis examines the tradition of half-timbered buildings in V?stra G?taland County as there is a current lack of research on this building category in this region. The lack of knowledge may lead to the loss of potential cultural heritage values if these buildings do not receive attention. Therefore, the study aims to provide a more comprehensive understanding of its role within the region. The goal is to expand and nuance the existing research on the Swedish building tradition, particularly in V?stra G?taland County and the general Swedish half-timbered tradition.

This thesis analyzes the expected profitability in land based wind power plants. The expected profitability is calculated on the basis of a wind power project in Vartofta, Falköping. The information required to calculate the expected outcome is then concentrated to this project, which is in this thesis called project Näs. In project Näs they plan to build three wind power plants, with each an effect of 2 MWh. These wind power plants are very capital intensive investments with a long and uncertain payback time.

Vattenfall hedge its future electricity production in order to decrease fluctuations in theresult. Hedging can in a simplified way be described as selling the future electricity deliveriesin long-term contracts so that the future price of the delivery becomes fixed. The contractsused are electricity forwards traded at the Nordic electricity market Nord Pool. Animbalance between buyers and sellers can lead to a situation where the forward price notequals the expected spot price. The difference between the forward price and the expectedspot price is referred to as the market risk premium.

Climate change is the modern society?s common issue. The developed countries areconsuming more than what is sustainable, and the climate change due to the use offossil fuels can be seen clearly. EU has specified goals, in order to stop furtherdamage, which demand that every member state have to reduce its energyconsumption by 20 % before 2020 and 50 % before 2050, relative to 1995.The Swedish government uses a number of instruments to encourage reduction in theusage of energy, but every individual has to contribute to reach the goals.With increasing energy price the cost of living is going up. A lot of people are lookingfor ways to save energy and not be affected as much by the increasing price.Investments for insulation, replacement of windows and replacing old heating systemfor a new efficient heat pump is getting more and more common.This thesis is about investigating the possibilities in becoming independent from buyingenergy for households.

This thesis presents a method of making repairs in log houses. The purpose of the thesis is to use this method to exemplify crafters practical intellect. The method is based on the use of a template board to transfer the measurements onto the new log. There is a dearth of literature dealing with timber repairs, and the literature regarding using a template board for this is non-existent. The description of this method has therefore been compiled from interviews with active timber crafters.

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

 Problem   Are there any abnormal changes in the parent company's share price at the news of a spin?off.ObjectiveThe main purpose of the study is to investigate how the news of a spin-off affects the parent company's share price. In other words if the news of the Spin-off gives an abnormal return on the Stockholm Stock Exchange during the specific period of 1998?2008. In addressing this, the paper will also investigate the following sub sections: are there any differences in the abnormal returns in various sectors and what the reasons to perform a spin?off in the Swedish market are.MethodAn event study in which market data is used to measure specific events? impact on the value of the company and on the effects on the stock market.

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.

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.

The purpose of this essay was to try to find out if the optimal farrowing pen exists. By interviewing producers, veterinarians and salesmen and also through a literature study, I have tried to evaluate advantages and disadvantages regarding different types of pen formations and environmental details. The interviews with the producers showed that they all were satisfied with their particular farrowing pen. It also showed that one material can be functional in one farrowing pen but not in another. The determining factor for the outcome of the farrowing pen was the individual experience and the way of thinking of the producers. The veterinarians were of the opinion that there today were no existing farrowing pens that responded to the pigs needs. However, the results on the farms were generally good. The salesmen thought that the production costs could be lower if a sort of a standard pen was used.

Approximately ten people die every year at building sites in Sweden. Every year TheWork Environment Authority (Arbetsmiljöverket) receives 3200 accident reportsfrom the construction sector. The Swedish building contractor Skanska has the vision:?Zero accidents?. Only at Skanska Sweden, where this diploma work is preformed,350-520 accidents and mishaps are reported every year for the last 5 years.

This paper analyses how Swedish fine-art oil paintings sold at auctions has performed as a monetary investment during the period autumn 1985 until spring 2006. An average price technique as well as a hedonic regression technique, applied to a sample of 19 213 auction sales, is used to construct price indices. The indices show somewhat different results, which is explained by the inability of the average price model to adjust for relative differences in quality between periods. The hedonic regression model on the other hand captures this effect, why the hedonic index is applied in a financial return model. By adjusting for transaction cost, the financial return of an average investment in paintings is calculated.
