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.

Background: The devolopment in the exchange market has attract a large number of investors. The information flow is extensive and it might be hard to follow the dynamic market. Some investors therefore choose to place their capital in a stock portfolio which is manged by a professional firm with no influence from the capital owner, this management is called discretionary managing. Purpose: the purpose of the thesis is to examine the working methods and the rationality regarding the management of the discretionary portfolios. The purpose is also to try to examine whether there is a relation between the selected risk, return and fees.

In this paper the effect of capital structure on profitability has been investigated among Swedish companies. The essay intends to examine how the relationship between debt and profitability appear among Swedish companies and if the relationship differs between industries. The purpose is to find out how debt affects the profitability of Swedish companies.A quantitative approach has been applied. The selection was made among companies listed on Nasdaq OMX Stockholm, which resulted in a sample of 207 companies. Several regression analyzes has been formed, based on the independent variable debt-ratio and the dependent variables profit margin, pre-tax profit margin, operating margin, return on assets and return on equity.

People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).

ABSTRACTTitle: The exact title used in the thesis will be mentioned here.Level: Bachelor thesis in BusinessAuthor: Mattias Lindqvist & Jonas TesfaySupervisor: Peter LindbergDate: 2011 ? JuneAim: In Sweden the representation of women on company boards is discussed extensively. It has also been suggested that regulations such as quotas should be imposed, in hopes of getting the gender balance on the board of directors. Measures such as these have been presented when this problem attacks our democratic values about how a society should look like. The aim is to study and analyze whether there is any connection between the return on assets and the proportion of women on company boards.Method: The paper is made from a quantitative with a deductive approach.

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

Although Lean has received an increased amount of attention in the service context, research still has not established how successfully Lean manages to increase service productivity; since service productivity consists of both efficiency and quality. Research regarding productivity discusses the risk of a tradeoff between efficiency and quality in service production processes. Therefore, this thesis aims to explore if the tradeoff in a production setting with low variability in demand and low customer participation exists, after Lean has been implemented. With a qualitative approach, a case study has been conducted at Scandinavian Airlines Ground Handling to evaluate the effects of Lean in the baggage handling process. The result of the study shows that the tradeoff has not been overcome; efficiency has increased at the expense of quality.

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Bakgrund: Tidigare forskning har visat att insynspersoner tenderar att överavkasta påinvesteringar i eget bolag. Det råder dock delade meningar kring varför insynspersonertenderar att överavkasta. Vid genomgång av tidigare studier påträffades ingen kvalitativstudie, varav vi ansåg det vara av intresse att studera fenomenet genom intervjuer medinsynspersoner.Syfte: Uppsatsen syftar till att studera och kartlägga motiven bakom insynspersonersköp- och säljtransaktioner i eget bolag. Med hjälp av tidigare forskning samt en ny infallsvinkeli form av teorier inom behavioural finance analyseras varför insynspersonertenderar att uppnå överavkastning på investeringar i eget bolag.Genomförande: Studien har genomförts med utgångspunkt i åtta intervjuer med insynspersoner.Resultat från tidigare studier på området låg till grund för vilken informationvi med intervjuerna ville uppnå djupare förståelse kring. Den insamlade empirinhar analyserats utifrån empirisk forskning och teorier inom behavioural finance.Slutsats: I studien presenteras en ny hypotes vilken förklarar insynspersoners överavkastningsom en följd av befintlig lagstiftning.

We investigate if the size of goodwill compared to total assets has any effect on the shareholders return on companies listed on the Swedish Stock market. We put up two different hypotheses with a foundation from previous research and later dismiss one of them. Our evidence does not show any indicators that the size of goodwill have an effect on the shareholders return, which brings us to believe that there, from a share holders point of view, isn?t any need for concern regarding the standards about accounting for goodwill as stated by IFRS. .

Purpose: The purpose of the study is to in a comparative and causal way explore whether there is a relationship between risk and return and also how it is perceived on the Nordic financial markets.Theory: The theoretical frame of reference applied in the thesis is considered relevant inthe perspective of the study?s purpose and research questions. We have among other theories used The Capital Asset Pricing Model, The Efficient Market Hypothesis and various Behavioural finance theories.Method: The study has its starting point in a quantitative approach with a quantitative data analysis supported by secondary data extracted from Thomson Reuters.Empirics: The empirics contains regression analyses made from calculated secondary data of 240 randomly chosen companies from Nasdaq OMX Stockholm, NasdaqOMX Copenhagen, Nasdaq OMX Helsinki and Oslo Bors.Conclusion: The study conclusions show that there are both a negative and positive relationship between volatility and actual return on the investigated markets. Considering this prior statement we can conclude that the Capital Asset Pricing Model can?t correctly describe the actual relationship between the parameters investigated on the current sample.

The economic prerequisite to many farmers in Sweden after the EU membership and the new agriculture policy has generated large demands on the farm management. Until year 2004 you got a grant based on what you had produced and not on consumer demand. In 2005 a new economic aid (Mid Term Revue) was introduced and the conditions has changed again. Due to this I have chosen to do a cost-benefit analysis on a case, to investigate if the present production is sustainable in the future. My conclusion is that the profitability is acceptable even if the farm has a high debt. But to make the production more profitable the products produced should be refined as much as possible at the farm, to get maximum economic return.

In recent decades, mental illness has increased in Sweden, and in parallel to this there has been an increase in unemployment. This implies that it is harder for people who have been away from employment for long periods due to ill health to return to work. The purpose of this study was to examine the work situation of people with mental illness who had undergone prevocational training, and to identify psychosocial factors relevant to their current work ability. The aim was also to describe how those who had undergone prevocational training perceived that it had affected their work ability. The study involved 19 participants who were interviewed and assessed with the Worker Role Interview, and an open question was asked about how they perceived that the prevocational training had affected their current work ability.
