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.

The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for Market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..

Background: Low Price-Earnings ratio, low Book-to market ratio and low stock prices can give the impression that a stock is ?cheap?. Is it through systematic use of these portfolio strategies possible to beat the market index ? in other words does financial illusions exist? Purpose: To examine if the Stockholm Stock Exchange is an efficient market. Limitations: The efficiency is tested solely through the chosen portfolio strategies: low Price-Earnings ratio, low Book-to-market ratio and low stock prices.

This study investigates a method for identifying human capital and its effect on company valuation. We devise a measure for the efficiency of human capital based on the personnel cost. We include all companies listed in the financial and industry sector on Nasdaq OMX Stockholm in an attempt to examine human capital and its effect on firm valuation. Our results indicate that a higher efficiency of human capital has a positive effect on return on assets. However, we find that our measure can be interpreted in two ways; either as a firm?s level of human capital efficiency or its dependency on human capital, to achieve its net sales and revenue.

This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.

This essay will explain the effects of decentralisation, and what impact it has on the efficiency to create a better integration for immigrants on the Swedish labour market. Examples of literature that has been examined are Marcus Gossas and Jon Pierre. From these authors, I have been trying to explain the relationship between decentralisation, cooperation and efficiency.Since the end of the Second World War until the middle of 1980, Sweden mostly received labour immigrant. Since then, the immigrant pattern has changed to consist of mostly refugees. Changed immigration patterns together with increasing debts for the Swedish government has lead to decentralisation and cooperation between public authorities has therefore become a target to reach better efficiency.

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.

A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of Market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.

The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

This paper examines job coaching on the Swedish labour market. The study uses trygghetsråden, which are organizations established by an agreement from the labour and employer side, as a starting point for the study. In addition, the study examines the phenomenon from the perspective of the job coaches themselves and the coaches clients. The study concludes that job coaching is defined by the coach and the client's common goal of finding a suitable match for the client on the labour market. The job coach helps the client reach the goal of an appropriate job by making him or her aware of his or her competences and preferences.

The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency.

AbstractThe market?s demand to purchase more cost effective products is continuously increasing. The producers are forced to become more efficient and flexible with resources to produce high quality products at a low cost in order to maintain or increase market shares. With this in mind Isaberg Rapid AB is requesting a project to increase efficiency in the assembly cell of hammertackers. The company has found in Kaizen-events that there is a potential of efficiency improvements in the assembly group that has not been achieved.The objective with this paper is to identify the major factors that influence the efficiency in the assembly cell for hammertackers.

The Swedish TV broadcasting market is constantly changing together with the players in it.

This thesis examines the relationship between OECD-DAC and Civil Society Organizations (CSOs) within an aid efficiency context. The ability for these two actors to cooperate is highly important and determines the outcome for a major part of the development aid in the new millennium. The development agenda for the new millennium emphasizes aid efficiency as a key to a more successful aid, and this requires increased cooperation between all actors. The analysis made is a discourse analysis. The discourse of aid efficiency is analyzed, both its preconditions and results.The analyze finds out that there is a gap between OECD-DAC and CSOs in terms of how to handle aid efficiency.

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.
