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.

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.

When constructing a road the risk of emission of substances from the used materials to the surrounding environment has to be evaluated. The aim of this study is to present a proposal for how to evaluate the risk of contamination as a result of emission from the materials in a road construction. The study is based on literature studies, an inventory and a questionnaire that examines how experts in governmental agencies, industries and universities evaluate the risk of contamination. The inventory indicates that guidelines for evaluating the risk of emission from secondary materials in a road construction do not exist. The conclusions from the questionnaire are: that there is no common way to evaluate the risk of contamination as a result of emission from materials in the road construction, there is no uniform interpretation of the terms "minor" and "significant" risk of contamination and that the evaluation is subjective.

The purpose of this Bachelor Thesis is to investigate whether the introduction of IFRS, and in particular IAS 40 regarding fair value accounting of investment property, has lead to increased financial risk for Swedish real estate companies. Financial risk is measured using several financial risk ratios during the period 2000-2009, effectively covering the period before and after the introduction in 2005. The financial risk is found to actually have decreased significantly in comparison with the control group. The relative decrease supports the notion of a factor unique to the real estate companies at least partially driving the change, possibly IAS 40. However, this change is, due to the statistic method employed, only an indication of the direction of change, and consequently interpretations of the magnitude of change cannot be made.

The conditions for a good silage process start with good wheather and choice of crop, then choice of harvesting machinery. The shorter and more mechanically treated crop, the better quality of the forage. (Pauly 1994). This study has examined the variations in chopping length depending on harvest method. Precision choppers works with a rotating chopping cylinder, where the crop is cut into pieces.

This paper is a study how students at a high school in Falun, Sweden, estimates theirperformance in an upcoming math test which is then compared with the actual grade thestudent performed. The students who participated also answered questions related to ?risksituations? to examine whether there is a correlation between how students estimate theirperformance in the context and their risk behavior, and if the students act like economicmodels assume. In agreement with previous studies, the boys in the survey tended to beoverconfident in their performance. The girls in the study were neither over- norunderconfident in her performance and no significant difference in the estimation of one'sperformance between the sexes could be proven.

I denna uppsats undersöks om världshändelser skapar abnorma effekter hos oljebolags aktiekurser och om dessa effekter ter sig olika beroende på företagens olika storlek. Undersökningen utförs med hjälp av en eventstudie som genomförs på sex oljebolag med tre världshändelser som utgångspunkt. De valda världshändelserna bestod av två naturkatastrofer och en större ekonomisk händelse. Företagen som valdes delades in i två grupper om tre företag, där ena gruppen innehöll de större företagen och den andra gruppen de mindre.Slutsatserna som har kunnat dras av undersökningen är att händelserna i två av de tre undersökta fallen orsakade signifikanta abnorma under- eller överavkastningar hos oljebolagens aktier vilket bevisar en viss ineffektivitet hos marknaden. Det generella utfallet var att den ekonomiska händelsen visade sig ha en större påverkan på aktiekurserna än de två naturkatastroferna hade.

The purpose of this essay has been to study if the social services adjust the choice of institution to every juvenile's need of care. If the choice of institution isn't adjusted to the juveniles the institutional placement can become a way to store them rather then treat them.To accomplish the purpose of the essay we have interviewed ten social workers with different worktitles and positions. We have delimited the study to three swedish communities with varying sizes. We have analyzed the material with Bourdieus theory of "field" and "doxa" and Antonovskys theory "a sense of coherence" (SOC).We came to the conclusion that the social service adjusted the choice of institution to the juveniles needs as much as possible. Although there are a couple of factors that some times makes the best choices impossible.

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.

This dissertation aims to explore how an investment appraisal differs depending on if it is conducted by a municipal or a private real estate company. Municipal and private real estate companies are not performing on totally equal terms in the property market. A municipal company in Sweden has a public service mission. The consequence due to that mission is that they have limited yield potential but on the other hand the right to certain subsidies. They are also limited by the law of public purchasing (in Swedish: Lag om offentlig upphandling) in the investment process.

There are many different forms of financing for small businesses and two common financing options mentioned in the study, bank loans and Venture Capital.Venture Capital is a form of risk capital financing, investing in unlisted stock market. The feature of the arrangement is that those people are trying to find companies that can offer unique, attractive and in demand products on a strong growing market. Since VC-firms are taking a big risk in cooperation with the investment, the VC-company strong demands while assessments are made on the company will generate a return in the future.Bank loans are the most common form of financing for companies in the market. Requirements and assessment under the law is hard especially for small businesses because financing entails high risks. Banks require that the liquidity management in the enterprise should be stable because the bank's main objective is to repayment of debt and the interest payable on the capital.The purpose of this study is to examine the requirements and assessments VC-firms and banks make use of the financing of small businesses. .

The grain market is facing substantial changes. Tradionally, cereal has been a supply-led market i.e. supply conditions have had a major impact on price level or indirectly, through market interventions implemented through the Common Agriculture Policy (CAP). Just a few years ago, Sweden and the EU were not affected so strongly by world market prices for cereals. EU was a surplus-area and to a substantial degree a local market.

Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.

A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.
