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.

Stockholm has in recent years experienced a strong population increase but despite that fact, the demand for housing has not been followed by enough housing contracts. According to forecasts, growth in population will further be continued upward. With more condominiums than rental units on the market, new apartments are too expensive to live in. This creates unsustainable problems for those in lower classes of society. Creating a housing market in the periphery of Stockholm is not sustainable from a social perspective.

Chapter 1. 1 § jordabalken (1970:994) defines property as land that includes area, which is divided into properties.A three-dimensional property must be firm with a closed volume where top and bottom are specified. The property boundaries are described clearly according to Chapter 4. § 27 fastighetsbildningslagen. A three-dimensional property can undermine a traditional property, as well as a three-dimensional property.

The change in the information society has affected the development of the labour market for information specialists and informants as well as their roles. Companies are now aware of the fact that information specialists have a variety of important skills and competence that is important for them. The goal of this thesis is to see what defines an information specialist and an informant and also to find out their situation on the labour market. The similarities and differences between the two professions will also be discussed in the thesis. The main method used is the investigation of the job advertisements in the journal DIK-forum from the year 2000 and year 2004.

On December 1th 2009 the Lisbon Treaty entered into force, and through Article 13, the recognition of animals as sentient being was given a more visible part in the very core of EU law. This was an effect of a political decision to commit to the issue, partly because of the will to further harmonize the EU market, but also due to increased societal concern for the wellbeing of animals. Over the last decades, ethical awareness is growing in many countries, one reason being new scientific discovery. This influences legislators and policy makers to take proper action, and in this way, ethics and science often work together as the very basis for the development of new legislation and policies. There is yet to be seen what the actual consequences of Article 13 will be, since the legal obligation remains the same and there are still some reservations in it.

The construction market has, as a result of the crisis in Europe been uncertain in recent years. During the year 2013, the construction will be stabilized, in particular Finland. The geographical proximity between Sweden and Finland and similarities in cultures and climates makes Finland a coveted market for many Swedish companies.Differences in national regulations and guidelines, which are produced by the authorities in different countries, are examples of barriers that may hamper the process, including for Swedish villa suppliers, to establish themselves on the Finnish market. It may be useful when facing a new export drive, to look up what similarities and differences there are between the countries building codes, to prevent mistakes and unnecessary costs to the project work..

Today's labor market is characterized by flexibility. This applies to organizations, forms of employment and working time. Unregulated working time is such an adaptation and the main subject of this essay. The purpose of this study was to investigate the conditions that underpin unregulated working time, in relation to the Swedish legislation and to EU legislation. The intention has been to investigate the work environment impacts of unregulated working time, and what differences there are from a gender perspective.The conclusion is that workers who enter into agreements for unregulated working time have significantly different terms from traditional workers.

The main purpose of this essay is to investigate if Latvia´s pattern of trade has become more similar to the mature market economies, after Latvia´s independence 1991.Today, the intra-industry trade (IIT) dominates the trade of mature market economies. One of the pioneers of intra-industrial trade is Paul Krugman, who was the first to emphasize the importance "of scale and consumers' desire for variety" in explaining the basis for modern commerce. Customers get more variety and usually cheaper goods when the market gets bigger. I mainly use the modern trade theories to explain the trade pattern in Latvia. To measure how Latvia has developed its intra-industry trade, and thereby is approaching the mature market economies´ trade pattern, I use the Grubel-Lloyd index (GL-index).

The Swedish system of rent control has recieved a lot of critique for creating an ill-functioning housing market. Supporters however claim that a movement towards market rents would lead to increased segregation. We evaluate whether rent control has managed to counteract segregation in Stockholm. Our evaluation is based on a data set of 292 representative households in Stockholm. We find that residents in rent controlled apartments in attractive locations typically are born in Sweden by Swedish parents and that they are likely to have a higher income than residents in rent controlled apartments in less attractive locations.

After the formation of the European Union internal market in 1992, member state specific obstacles and barriers were largely removed. This was especially the case in harmonised industries where standardisation and technical regulation have led to legal certainty. Despite this, a large range of trade regulation continues to remain distortional to trade, in addition to the ongoing tariffs and subsidies. The key trade regulations relate to a number of areas involving technical regulations such as production labelling and the protection of intellectual property rights. Whilst policy makers claim justification based around the need to correct market failure in delivering desired outcomes, the question is whether these regulations are appropriate responses to market failures or if they have simply been imposed in an attempt to protect domestic markets.

The main purpose of this essay is to study the Swedish labor law concerning employees who are, aspire to be, or are expected to become parents, both men and women. Thereby accomplishing a gender perspective on the issue at hand. The study also take in to account the laws issued by the European Union, and their impact on the Swedish law system, so as to gain an international perspective. The laws regarding parental leave, both Swedish and European, involve protection for workers from being treated in a less favorable way than someone in a comparable situation, as employers are forbidden to disfavor any employee or job-seeker in basically all situations in the work place or in a recruiting context, if the disfavor is in any way related to the parental leave. The only situation where an employer is allowed to disfavor an employee regarding his or her parental leave, is if the disfavoring is a necessary consequent of the employee?s absence.

A protection helmet for young people (3-7 years) in winter environment has been developed in this thesis. The result is a concept proposal for development at STIGA Sports AB in Eskilstuna. This thesis work has been performed during 20 weeks, for a Master of Science in Product and Process development at Mälardalen University Eskilstuna Sweden in September 2009 to January 2010. The helmet is shown as a CAD model with detailed solutions to the outer shell, interior and adjustability (in sizes 50-56 cm) which are the three focused areas in the development. Also a physical model in scale 1:1 has been developed and is shown in this thesis work.To achieve the best result possible the process started with an analysis of the market and the product.

Tidigare forskning har indikerat att det kan existera informationsasymmetrier i aktiemarknaden mellan olika marknadsaktörer. Personer med insyn har oftast tillgång till särskild information som inte är tillgänglig för marknaden. Detta innebär att möjligheter till abnormala avkastningar existerar för dessa personer vid handel av bolagets finansiella instrument. Denna studie undersöker i första hand huruvida insynshandel på Aktietorget och Nordic Growth Market genererar abnormal avkastning samt om det föreligger en skillnad i resultat mellan dessa marknadsplatser. Det som ligger till grund för studien är insiders samtliga köp- och säljtransaktioner under 2005 för bolag noterade på Aktietorget och Nordic Growth Market.

The market risk premium is one of the most important parameters in finance. Its value and the ways to calculate a risk premium for the market is a widely debated subject. This thesis examines numerous ways of calculating a risk premium for the Swedish market with regard to how good an estimation they make of a real risk premium. Estimations based on historical periods ranging from 20 to 85 years is calculated as well as a premium based on forward-looking estimates. The real risk premium is solved out for a selection of companies and an index with the help of CAPM.

Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..
