Bryggor - En studie av bryggors förekomst i publika bolag och påverkan på träffsäkerhet i analytikerestimat av EPS
Previous studies have shown that there is a relationship between voluntary disclosure and analysts' forecast accuracy. However, there has been no research conducted specifically on bridges. Bridges contain information on how components such as price, volume, foreign exchange rates and acquisitions have impacted the financial performance between two periods. The main purpose of this thesis is to investigate the usage of bridges in quarterly financial information of companies listed on Nasdaq Stockholm. We provide a descriptive mapping of bridges and find that 30 out of 268 companies are presenting bridges as a part of their voluntary disclosures, with large firms being the most frequent users.
Ny princip för spänningsreglering i Fortum Distributions mellanspänningsnät i Stockholm.
The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.
Cross-Border Listings and Price Discovery: Evidence from UK- and US-listed Swedish Stocks
Objective: The objective of this study is to examine the extent to which the London stock exchange and the US stock exchange Nasdaq respectively contributes to the price discovery of Swedish stocks listed on the Stockholm stock exchange, the London stock exchange and the US stock exchange Nasdaq.Method: The study is a replicate study of the studies by Grammig, Melvin and Schlag (2000) and Eun and Sabherwal (2003). The methodology is based on the methodology of the latter study. The data material consisting of quoted stock prices for three Swedish stocks on the three stock exchanges at five-minute intervals during a 49-day-period in 2003 has been run through different statistical tests in a five-step process.Conclusion: The evidence of this study shows that prices on SSE, LSE and NASD are cointegrated and mutually adjusting. The evidence suggests that in all three cases, price discovery takes place on the home stock exchange SSE. Moreover, LSE contributes more to price discovery than Nasdaq.
Efterfrågeprognoser : ?En jämförelse av prognosmodeller med avseende på FMCG-marknaden?
An organization must manage its resource consumption and material flows in order to satisfy the demand of its products as efficiently as possible. Managing of the aforementioned requires a balance between the organizations resources (such as the capability of distribution and production) and the market demand. According to Gardner (1990), an estimation of future demand is a necessity for maintaining the balance. An instrument that is used frequently to estimate future demand is demand forecasting. The demand forecasting practice has been thoroughly studied and a plethora of academic contributions exist on the topic.
Får vi se ? datakvalité. Effektivisering av supportprocessen hos Tunga Maskiner AB
Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.
Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations
The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.
Är det lönsamt att ta hänsyn till temperatursvängningar? : En fallstudie om prognostisering på Karlstads Energi
Being able to predict the future had been an invaluable competitive advantage for any corporation. Forecasting is a vital part of any business, hence a good forecast allows enterprises to invest in a beneficial way. However, there are several ways to prepare forecasts and the forecast methodology can vary. An industry that is dependent on forecasts is the energy industry. By predicting consumers' energy consumption, Swedish energy companies can hedge on the Nordic power market Nord Pool.
Kommersiella Fastighetshyror och Finansiell Stabilitet
In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.
Internprissättning : Bevisbörda, dokumentationskrav och rättssäkerhet
As the globalization of companies increases day by day, the need for a clear and comprehensible legislation to overcome the problems with transfer pricing transactions increases as well. Incorrect pricing in transfer pricing situations between companies with close economic ties to each other makes countries risk parts of their taxation income.Swedish legislation uses the internationally accepted arm?s length principle to regulate the transfer pricing transactions. Through the correction rule, the rule is upheld that the pricing between two companies with close economic ties to each other must apply to the same conditions as it would have been if it was between two companies without close economic ties to each other.To ensure that enough material is provided to base the assumption whether or not the correction rule has been followed or not, Swedish legislation provides a number of paragraphs to regulate the matter. The legislation is spread all over and is hard to interpret.
Fastighetsaktier och inflation : Kortsiktiga och långsiktiga samband
The purpose of this paper was to examine the inflation hedging capabilities of property shares. A common notion is that property is a good hedge against inflation. Indeed, positive correlations have been found for direct investments and inflation. However, property shares are generally perceived as a perverse inflation hedge. This discrepancy has often been quoted as evidence of property shares divergence from the development of the underlying property market.
Strömningen i och över en skog : utvärdering av en 'mixing-layer' hypotes
A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations that give the wind profile. The theory has been used to calculate wind profiles for sixdifferent atmospheric stabilities.
Växelkursprognoser för 2000-talet
Titel: Växelkursprognoser för 2000-talet Ämne/kurs: NEKK01, Examensarbete C, 15 högskolepoäng Författare: Kenth Hedberg Handledare: Thomas Elger och Fredrik NG Andersson Nyckelord: Sverige, nominella växelkurser, prognoser, UIP Syfte: Syftet med uppsatsen är att fylla tomrummet av att det bara finns ettfåtal svenska studier för 2000-talet. Uppsatsen kommer att belysa hurden nominella växelkursen ska prognostiseras för att matcha defaktiska värdena på bästa sätt. Metod: Tillvägagångssättet för denna uppsats är att skapa prognoser utifråntre olika prognosmetoder som sedan jämförs med de faktiska värdenaav den nominella växelkursen. Det bestäms sedan utifrån treutvärderingskriterierna vilken metod som därefter ger det bästautfallet. Slutsats: Visar att AR(1) och AR(1) med ränta prognostiserar bättre än randomwalk med en kortsiktig prognoshorisont.
Kommunikationseffektivitet och kommunikationsstrategier för L1- och L2-talare i referentiella problemlösningsuppgifter
This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.
Undersökning av modulationsscheman för existerande bredbandsteknologier
In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.
Sambandet mellan förändringar i fonders portföljsammansättning och prestation : Effekten av ett nytt aktivitetsmått
Tidigare forskning är inte enig om aktivt förvaltade fonder presterar bättre eller sämre än index. Då hänsyn inte tas till olika nivåer av aktivitet tycks de flesta studier visa att aktiv förvaltning är en förlustaffär för fondsparare. Vi introducerar ett nytt mått på aktivitet, aktivitetsgrad, som utgår från de åtgärder förvaltaren vidtar. Aktivitetsgraden definieras av mängden och storleken på förändringar i portföljsammansättningen som sker under ett kvartal. Vi undersöker aktivitetsgraden hos 22 svenska småbolagsfonder mellan 2008 och 2013 och finner att de flesta fonder har en låg aktivitetsgrad.
