Konkursprognostisering i en svensk kontext : En modell utvecklad för svenska småföretag
Konsekvenser av konkurser drabbar såväl företaget själv som andra intressenter. Exempel på sådana är investerare, kunder, leverantörer, långivare och staten. Att utveckla ett verktyg för att kunna analysera ett företags väg mot konkurs är därför ett bidrag till såväl företaget själv som samhället. I den här studien har vi utvecklat en modell som kan appliceras på småföretag inom kategorin aktiebolag i Sverige. Den kan användas för att prognostisera konkurs för 18 månader framåt i tiden.
Bootstrap som hjälpmedel att öka noggrannheten och bedöma precisionen vid probitregression, med tillämpning på hörselmätningar
In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), ?, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estimated; the interest centres around m = -b0/b1, i.
Färdvägsmiljöer vid cykling för transport : En studie av en modell om uppfattningar av färdvägsmiljön hos cyklister
SummaryAimThe study examines a theoretical model developed to capture cyclist´s perceptions of the route environment. The survey focuses on if level two and three in the theoretical model captures what it´s intended to do. More specific we ask ourselves how the three appraisals (unsafe/safe by traffic reasons, stimulating/inhibiting route environment, unsafe/safe by other reasons) in the model´s second level relates among themselves and if these three appraisals can capture the degree of environmental well-being/unwell-being in the model´s third level. The questions were: Do the three appraisals differ among themselves? What is the difference/-s in such cases? And, is there a correlation between any of the three appraisals and environmental unwell-being/well-being? What is the correlation in such case? MethodThe gathering of data was done through questionnaires.
Styrelsesammansättning och lönsamhet i svenska aktiebolag
In this thesis we examine the relationship between board composition and firm performance in Swedish companies. The selection of companies includes all Swedish limited liability companies, with the exception of micro enterprises, that have been active between the years of 2009-2010. We develop hypotheses based on resource dependence theory, agency theory, and the resource based view, and test these with Regression Analysis against collected data. Specifically, we examine the effects of board diversity, outside directorships, and CEO duality. Our findings show that none of the theories provide sufficient explanatory power of the relationship between board composition and firm performance, and that further research is required to better understand the role and effects of company boards..
Analys av åldersstrukturen hos sik (Coregonus lavaretus) i sjöar utan gädda (Esox lucius)
Development of morphs within European whitefish (Coregonus lavaretus), might be considered as a beginning of a sympatric speciation process. Unpublished data suggests that presence of the keystone piscivore northern pike (Esox lucius) is the main driver of sympatric divergence in European whitefish (Coregonus lavaretus). Using introduced whitefish populations as controlled experiments, it is possible to determine when different characters diverge in the speciation process. In this study, I analysed age and growth within European whitefish populations of different age to assess if these characters change over time in absence of pike. With using otoliths from whitefish populations of different age, I was possible to determine individual age, and by measuring the length of the fish, growth was calculated.
Analys av institutionell kapitalförvaltning: Stiftelserna som bildades ur de forna löntagarfonderna
This paper studies the research foundations created in 1994 from the former wage earners? funds out of a portfolio management point of view. Firstly it describes the seven largest foundations and their different portfolio management structures. Secondly it analyses the performance of these foundations measured as the intercept, Jensen?s a, in a linear regression of the excess returns of a portfolio versus a proxy for the market, as well as the Sharpe-ratio.
Frivillig revision - Vad avgör rekommendationen? : En studie ur revisorns perspektiv
Aim The aim of the thesis is to explain the factors that affect the auditor's recommendation concerning audit services to customers who are not subject to mandatory auditing.Background and problem In 2010 mandatory auditing for small companies was abolished. It is common for the auditor to provide recommendations re-garding whether or not a customer should chose to retain the audit. The question is which factors can explain the auditor's recommendation.Method and empirics This thesis uses a deductive approach with inductive elements and a combination of qualitative and quantitative data is used. The qualitative data consists of a pilot study and the quantitative data consists of a questionnaire survey. The analysis of the empirical data was performed using Regression Analysis.Theory This thesis applies an eclectic approach where the starting point is legitimacy, institutional theory, professional theory and decision making theory to develop a model.Results and conclusions The notion of the recommendation as well as the extent of the recommendations can be explained by factors related to the auditor's agency affiliation and the auditor's personal qualities..
Förklaringsmodell för cykelresor i Trondheim : Fysiska och demografiska faktorers betydelse för det geografiska resmönstret
The work examines geographical variations of bicycle use in Trondheim municipality with the aim to create an understanding of what influences the use of bicycles and explain the geographical travel pattern for cycling. The work focuses on the how physical structures generates different transports effects. Where bicycle travels in Trondheim municipality are undertaken is described by using network analysis in ArcGIS, based on aggregated data from the travel habit survey (RVU) in 2009/2010. Trondheim municipality is divided into smaller geographical units (zoner) whose characteristics are described by 19 variables, categorized into 6 groups; Distance, Land use, Topography, Bicycle Facilities, Road characteristics and Demographic factors.By linear Regression Analysis in SPSS and ArcGIS Spatial Analyst, an explanatory model is elaborated. The variablesdistance to the regional center, workplace density, percentage separate bike paths and hilly terrain explains 78 percent of where cycle journeys are undertaken.
Värderelevansen av Dirty Surplus Accounting Flows i Svenska Storbolag
Since the implementation of the revised IAS-1 in January 2009, the income statement has changed in order to include what is called dirty surplus accounting flows (DSF). Using data for the period 2005-2009 regarding large cap companies listed on the OMX Stockholm we identify DSF in Swedish accounting. First, we present some descriptive statistics on aggregated and individual DSF in Sweden. We find that aggregated DSF and individual items related to securities are significantly positive over time. Second, we perform a regression on returns to test for value relevance and find that aggregated DSF and individual items related to currency translation differences and cash flow hedges are value relevant in explaining returns.
En analys av variabler som påverkar bostadsrättspriser i Stockholms kommun : En multipel regressionsanalys över tiden
Denna studie har till syfte att undersöka hur betalningsviljan har ändrats med tiden förolika prognostiska faktorer på bostadsrätter. Resultatet kan användas för att förutspå prisutvecklingen på bostadsrätter som exempelvis kan användas som underlag för att skapa ett rättvist premiepris på försäkringar för prisfall på bostadsmarknaden.Undersökningen gjordes på 118 718 antal sålda lägenheter mellan år 2005 och 2013 i Stockholms kommun. Ett antal relevanta attribut och dess prognostiska faktorer på bostadspriset undersöktes med multipel regression. En regression gjordes per år varefter de prognostiska faktorerna analyserades och jämfördes.Resultatet av studien visar att betalningsviljan av boarea och avgift har minskat mellan år 2005 och 2013. För boarea minskar betalningsvilja med ökat antal rum vilket skulle kunna vara en effekt av bolånetakets införande.
Statistisk analys av journalmaterial från två stuterier : en retrospektiv studie
Retrospective data from two stud farms, in this study named stud farm A and B,
including 742 mares, was statistically analysed. Parameters included in the analysis
were type of insemination, date of the first insemination, number of inseminations,
the age of the mares, if the mares had a foal or not, foaling date, result of
pregnancy examination (if it was done), twin pregnancy and treatments given to
the mares. The pregnancy results and the treatments where compiled into a number
of frequency tables in which the mares where arranged according to age, month of
first insemination, foal or not and type of insemination. There was a significant
difference in pregnancy result between the years at both stud farms (2001 better
than 2002). At stud farm A, in year 2001, month (at start of insemination)
significantly influenced the pregnancy result.
Börsmisslyckande - En studie av misslyckade börsintroduktioner på Stockholmsbörsen
Vi vill med vår uppsats försöka hitta förklaringar till varför börsintroduktioner misslyckas. Med dessa förklarande variabler vill vi försöka skapa en modell som kan förutse huruvida en introduktion kommer bli lyckad eller ej.Teorin bygger på aktuell och tidigare forskning om misslyckade börsintroduktioner. Det redogörs även för förekommande begrepp och variabler.Vi använder ett kvantitativt angreppssätt för att besvara uppsatsens problemformulering samt uppfylla dess syfte. För att hitta de variabler som förklarar en misslyckad börsintroduktion använder vi oss av en logistisk regression.De variabler som vi funnit som kan förklara en misslyckad börsintroduktion är företagets ålder, dess skuldsättning, huruvida företaget är uppbackat av venture capital eller ej samt andelen kvarhållna vinster i förhållande till totala tillgångar. Den modell vi skapar förutser en lyckad respektive misslyckad introduktion i 69 procent av fallen..

Hur står sig Modigliani och Millers teori om kapitalstruktur under hög- kontra lågkonjunkturer? : en studie av 30 börsnoterade bolag på den svenska marknaden
Problem formulation: This paper will examine how the capital structure of firms affects their market valuation by applying the Modigliani-Miller theory on Swedish listed companies in a boom and a recession. The study will examine whether it is possible to draw any conclusions as to whether companies with high debt to equity ratios are valued lower in a recession, in comparison to companies with low debt to equity ratios.Purpose: To empirically test the Modigliani-Miller theory of capital structure in a boom and a recession in order to see if the companies? market value is affected differently depending on whether they have a high or a low debt to equity ratios.Methodology: The essay has a deductive and a quantitative methodological approach. Data analysis was done through a correlation analysis, a Regression Analysis and a hypothesis testing.Theory: The Modigliani-Miller theory of capital structure with taxes states that companies with a high debt to equity ratios has a higher value. One of the risks with a high level of debt could be that during a financial downturn companies have more difficulty realizing capital and are thus more likely to go bankrupt.Conclusions: The study shows results that are contrary to the Modigliani-Miller's theory; all the correlation analyses between debt to equity ratios and market value are negative.
Skuldlättnader som vapen i kampen mot korruption? : Om hur HIPC-initiativet påverkar korruptionsgraden i berörda länder
This paper examines how debt cancellation, given under the HIPC-initiative, has affected corruption over the period 2000-2006. The examination is foremost interesting due to earlier research showing that high corruption leads to unequal distribution of economic resources. This, combined with the objective of the HIPC initiative to reduce poverty, indicates that combating corruption must be successful in order to fulfill the goals of the initiative. A linear regression shows that countries that have benefited from the HIPC-initiative indeed have a lower corruption than other countries. A panel-data analysis shows on the other hand that no effect on corruption due to debt cancellation or reforms undertaken in the program can be confirmed..
