VD-byte : En studie av aktiekursens förändringar och rörelseresultat för företag som har genomfört ett vd-byte ur ett genusperspektiv
Syfte: Syftet med studien är att med statistiska mått undersöka om företags aktiekurs reagerar på ett vd-byte samt se hur ledarskap påverkar företagets rörelseresultat ur ett genusperspektiv. Metod: Undersökningen är en eventstudie som innefattar åtta stycken företag. Eventstudiens estimeringsfönster omfattar 56 dagar innan eventfönstrets 29 dagar, där aktiekursens rörelse undersöks. Varje företags enskilda procentuella förändring i rörelseresultatet kommer att studeras två år innan och två år efter ett vd-byte har inträffat.Teori: Undersökningen utgår från effektiva marknadshypotesen, agentteorin och signalteorin.Empiri: Resultaten för aktiekursens abnormala genomsnittliga avkastning (AAR) och den kumulativa genomsnittliga avkastningen (CAAR) visas i diagram, detsamma gäller för företagens procentuella förändring i rörelseresultatet. En jämförelse dras mellan företag som har genomfört ett kvinnligt vd-byte mot företag som har genomfört ett manligt vd-byte.Slutsats:Aktiekursen för företag som har genomfört ett kvinnligt vd-byte har cirka 10 procent högre förändring i AAR än för företag som har genomfört ett manligt vd-byte.Aktiekursens lutning på CAAR för företag med en kvinnlig vd är starkare än för företag där det har skett ett manligt vd-byte.
Bakom Fasaden
Although textbooks are scientifically proven that they are important and central to the school curriculum one should think critically about the content in textbooks - is it really compatible with the curriculum of following the textbook tradition? As a teacher there are different ways to reflect on which textbook to choose. It is important to compare several textbooks with each other and be aware that a textbook should follow the curriculum. A teacher examines many sections/topics in the textbooks, but in this paper only one section will be reviewed among four different textbooks. The section to be compared, in the paper, is the interwar period.
Fj?llen som en allm?nning En milj?ekonomisk studie om externaliteter i rensk?tselomr?den
Climate change is expected to increase the frequency and intensity of extreme weather events, with significantimplications for the financial stability of insurance markets. This study analyses how nature-related insurancepayouts and required solvency capital may develop over the period 2025?2099 under three emissions scenarios: RCP 2.6, RCP 4.5 and RCP 8.5, and what this means for the long-term sustainability of insurance as an economic institution. Using Monte Carlo simulation of a non-homogeneous Cram?r-Lundberg model, claimfrequency is modelled as a negative binomial process calibrated against SMHI's climate projections, and claimsizes are approximated by a lognormal distribution fitted to Swedish insurance data (NATY, 2015?2023).The results show that accumulated insurance payouts amount to SEK 96.7 billion under RCP 2.6, SEK 106.0billion under RCP 4.5 and SEK 131.9 billion under RCP 8.5.

Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner
Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Private Label-tillverkning : Faktorer som ligger till grund för att leverantörer på den svenska marknaden tillverkar private label
Background: In the past 10 years private label has increased significantly in the Swedish grocery market. This is an important strategic event, which is a great challenge to suppliers as it causes stiff competition. To handle this situation an increasing number of suppliers have to make the decision whether to produce private label or not.Purpose: The purpose of this study is to find and analyse factors that influence suppliers in the Swedish grocery market to produce private label. On this basis we intend to confirm or develop existing theories within the field of study.Research method: The study has a qualitative approach where empirical data has been gathered through interviews with suppliers and retailers in the Swedish grocery market.Results: This study has identified factors that underlie suppliers? decision to produce private label.
Bolagsskattens påverkan på marknadsvärdet : En eventstudie kopplad till kapitalstruktur
Sverige genomförde vid årsskiftet 2012/2013 ytterligare en sänkning av bolagsskatten. Denna gång från 26,3 till 22 procent. Målet med sänkningen var att hamna under EU?s genomsnittliga bolagsskattenivå vilket skulle minska företags incitament till att fly Sverige för lågskatteländer. Samtidigt ville regeringen minska företagens skuldsättningsgrad.I teorin sjunker värdet på skatteskölden vid en bolagsskattesänkning och därmed också värdet på företagen.

"Om man inte vet hur ett gammalt spöke ser ut, hur ska man då kunna känna igen gengångaren när man möter den?" : En undersökning av hur dagens läromedel för gymnasiet handskas med Sveriges rasistiska och fördomsfulla förflutna.
My goal with this thesis was to investigate how educational material in the subjects of history, geography and social studies relate to the fact that Sweden has a history marked by prejudice and racism.I have chosen to focus on four areas in the Swedish history that I think deserves some special attention, these four areas have been: the Swedish slave trade on the island of Saint Barthelemy in the eighteenth century, Swedish eugenics and oppression of the Sami people, forced sterilization services during the twentieth century and Sweden's aid and concessions to Nazi Germany during World War II. With these areas in focus I?ve studied three textbooks in the courses Geography A, Civics A and History A to se how they deal with prejudice and racism in the Swedish history.The result I have come to is that none of the books addresses all four of the areas I?ve focused on. Even if the books are taken as a whole the image that they convey is not adequate. In the event that the four areas that I?ve focused on been mentioned the information have been scant and rarely, if ever, has Sweden been paired with phenomenons like racism, slavery, colonialism, eugenics, forced sterilization, etc.
Terrorism - ett hot mot ekonomin? : En eventstudie om hur terroristattacker påverkar den svenska aktiemarknaden
Syfte: Huvudsyftet med studien är att undersöka om avkastningen på den svenska aktiemarknaden påverkas av terroristattacker. Delsyftet är att vid en eventuell påverkan undersöka om reaktionen skiljer sig mot landet där attacken skett samt hur lång tid det tar för de olika aktiemarknaderna att återhämta sig.Teoretiskt perspektiv: Den teoretiska referensramen utgörs av teorin om den effektiva marknadshypotesen samt behavioral finance med fokus på flockbeteende.Avgränsningar: I studien undersöks åtta olika terroristattacker och dess påverkan på aktiemarknaden i Sverige och landet där attacken skett.Metod: Studien är kvantitativ och använder ett deduktivt angreppssätt. För att besvara frågeställningarna tillämpas en eventstudie där två eventfönster används. Ett eventfönster på en dag och ett längre på elva dagar samt en estimeringsperiod som omfattar 30 dagar. Insamlad data används för att mäta den avvikande avkastningen som eventuellt uppstår efter att en terroristattack ägt rum vilket säger om attacken haft någon påverkan.Slutsatser: Terroristattacker har en påverkan på den svenska aktiemarknaden och i de flesta fall är påverkan negativ.
Akustiskt åtgärdsprojekt av en rockmusikklubb där live-musik spelas. Vad kan en audionom bidra med?
Introduction: The number of hearing impairments in Sweden is increasing. The largest increase is seen in ages 25-44. There are reasons to believe that these impairments are noise induced. Leisure time noise is not controlled in the same manner that industrial noise is. An ongoing conflict between city council officials and rock club owners, musicians and music event organizers about sound levels at smaller live music clubs exceeding the national sound level restrictions created the need for an acoustic intervention project.
