We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

The shareholder is supposed to be indifferent if one share costs 100 SEK, or 10 shares cost 10 SEK each. In an efficient market, shares should be valued directly to new expectations as a result of the announcement of the reverse split. We investigate whether abnormal returns incur surrounding reverse split and if owner structure change.One reason for the reverse share split is that most companies have plans to imple-ment other company?s specific events in order to survive rather than to change the price range to a more attractive level. We found a negative return in the ex-day at 8,1 per cent.

This thesis tries to define factors that impact upon the feeling of exclusivity for users on travelorganizers websites. We have identified seven key factors that we believe impact this feeling andthose factors are newsletters, special offers/auxiliary services, registration/limited information,price, limited number of seats on a journey, deals for members and personal service. To researchthis we have conducted a questionnaire and performed interviews with people that are familiarwith travel organizers websites. To create an understanding for the results we have studied usercenteredweb design, affective design and the meaning of pictures. The results show that personalservice and price are important factors to make users feel that they get their requirements andwishes met.

The Swedish consumer electronic industry has recently experienced an increasingly intensive price war. The price war has forced some operators in the business to declare bankruptcy, as the only way to compete has been by driving down prices. A challenge that retail chains in the consumer electronics industry is facing is to increase their margins. If store personnel can success with upselling, the companies will increase their profits. The purpose of this paper is to examine if the sales people in the consumer electronic industry can influence the customer to buy a more expensive product and what the effects the upselling has on the customers' attitudes.

Information technology and globalization has led to an increasing competition and service production has been more and more independent of locations. This has made a market of outsourced telephone costumer service possible. Due to high establishment the market has been saturated and with that price has sunk. Customer companies have the last few years got more negative to outsourcing of their telephone customer service as they through operating the customer service internally want to get closer to their customers.In the empirical study the writers try to figure out which companies the callcenters should try to aim towards to get long and profitable cooperation. This will be done through deducing guiding principles from theories about how different factors around companies costumer service should look like.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Traditional product features such as price, quality and supply service have been extended and nowadays includes environmental aspects as well. It raises new and increasing demands on haulier companies. The transport sector is responsible for a large part of the pollutants causing today?s environmental problems. The business is being closely monitored and to operate environmental friendly is seen as one of the most important elements for the industry?s future development.

With this essay we want to describe the transformation process that the real estate owner has to go through to sell the current rented flats to tenant. We also want to provide an understanding how the valuation is performed in the transformation process and highlight the issues that affects the price in the valuations. In the essay we would like to see if the valuation and the transformation process differ in a public real estate company compared to a private real estate company. Based on this we have asked us the following question to answer: -Is there any differences in how real estate?s are valued in the transformation process between public real estate companies and private real estate companies? We have used a qualitative approach to keep our main question.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

Syfte: Studiens syfte är att analysera hur flygbolaget Ryanair prissätter sina flygbiljetter och om det skiljer sig beroende på flygsträcka.Metod: En kvalitativ longitudinell studie med deduktiv ansats där primärdata i form av prisuppgifter samlats in från Ryanairs hemsida.Teorier: Prisdiskriminering, Priselasticitetshävstång, Operationell hävstång och Hallbergs prisstrategier.Slutsats: Studiens resultat bekräftar Anjos, Chengs och Curries teori om att lågprisflygbiljetter håller sig på en ganska stabil nivå fram till att det återstår ungefär 20 dagar kvar till avresa, då priset stiger fram till avgångsdagen då det är som högst. Detta motsäger Anderson och Wilsons teori om att biljettpriset går i cykler och att flygbiljetterna är som dyrast några dagar före avresa för att sedan sjunka i pris. Den höga prishöjningen på avgångsdagen sker konsekvent på alla de undersökta flygsträckorna och är intressant eftersom höga priser inte är något som lågprisflygbolagen vill förknippas med. Förklaringen kan vara det som diskuteras av Piga och Bachis om att flygbolagen försöker skapa en osäkerhet hos resenärer kring när det är billigast att köpa sina flygbiljetter. Studien resultat visar också på att det går att se ett mönster i prissättningen av flygbiljetter på Ryanairs resmål med få flygningar medan de mer populära resmålen har en mer dynamisk prissättning som är desto svårare att förutspå..

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

This thesis investigates the dynamics of the relationship between a leader and the followers within a chosen organization. The research on leadership has generally been focused on the leader, and consequently treating the followers like passive subordinates. We pursue a more multidimensional view of the subject, meaning that leadership descends from an interaction between leaders and followers, which makes it relevant to study the dynamics of the relationship from both perspectives. We chose to do a qualitative case study on a middle- and preschool which has won a price for being an ideal place to work at. This price peaked our interest to investigate why the relationships are highly functional in this particular organization.
