En empirisk studie av Value-at-Risk-prediktering med hjälp av GARCH-modeller
This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.
Om ekonomiskt bistånd och kriminalitet - En studie om socialt stöd och dess effekter på misshandel och stöld
Since criminality started to rise steeply in most western welfare states following the second world war the relationship between welfare support and criminality has been debated. For a period of time thought to be an effective preventive measure against crime welfare support has since from time to time come to be seen by some as ineffective and in some cases even as a contributing factor to the rise in crime. It remains a contested issue as new theories, such as social support theory, which is employed here, attempt to contribute to the understanding of what effects general welfare has on overall crime levels. As a connection which is relatively well-researched in the USA, altough still not yet fully understood, this study strives toward a better understanding by testing the relationship in a swedish context. The relationship might not function in the same way considering that the US is a fundamentally different welfare-regime than Sweden, liberal and social-democratic respectively.Untangling the relationship is attempted by employing a multivariate regressionanalysis on a crosssectional dataset consisting of data from 2012 covering 247 of Swedens total of 290 municipalities.
Prognosprocessen : En fallstudie hos Asko Cylinda AB
Balansering av tillgång och efterfrågan har alltid varit ett aktuellt ämne och för att klara av denna balansering krävs information om kommande efterfrågan. Denna information måste ligga så långt fram i tiden som det tar för att med säkerhet få hem exempelvis material. För att lyckas med detta använder sig företag i olika utsträckning av uppskattad framtida efterfrågan, så kallade prognoser. Prognoser kan definieras som systematiska metoder för att förutsäga framtida händelser.Problemet är att oavsett hur prognoser görs stämmer det prognostiserade värdet nästan aldrig överens med det verkliga utfallet. Många företag vet att deras prognoser inte är exakta utan att veta vad de ska göra åt saken.
Vi har i alla fall tipsbolag : En studie av möjligheterna att styra med belöningssystem inom kommunal verksamhet
Background: The use of reward systems can be of strategic importance as well as an affective mean of control for the organization in its work to achieve its goals. The municipal sector is characterized by its transparency and its responsibility for the taxpayer?s money. We therefore wonder which possibilities the municipal sector has to use reward systems as a men of control. Purpose: We intend to research the possibilities that the reward system offer as a mean of control for employees at the higher municipal level, with a special focus on commitment and motivation.
På vandring mot handling : Utbyte av perspektiv i landskapet
Sustainable Development is often described as a balance between ecological, economical and social aspects. Between these exists a complicated interaction that creates conflicts in the planning of the landscape. We see a growing need for a functional interaction between values and interest and an understanding for different perspectives. Cooperation and dialogue are key ideas with the focus on cooperation rather than the goal. There is a lack of forum for dialogue and cooperation within municipalities where a great knowledge and competence are gathered.
IT-konsulters organisationstillhörighet och hur den påverkar deras motivation
Problemområdet som uppsatsen belyser är sambandet mellan organisationstillhörighet och autonom motivation inom IT-konsultbranschen. Forskning om dessa områden har tidigare utförts främst var för sig, men har på senare år kopplats mer och mer samman. Dessutom har undersökningarna inom konsultbranschen enbart gjorts på bemanningsföretag. Utifrån sambandet och i förhållande till nuvarande teorier tas tre hypoteser fram och prövas.
Metoden som använts i undersökningen är en enkätundersökning bestående av frågor angående organisationstillhörighet och motivation.
Vad inneb?r agape och agapekultivering? En studie av samtida agapeteologi fr?n feministteologiskt och psykologiskt perspektiv
The main purpose of this study is to explore and develop how the Christian conception of love
as agape can be understood in light of feminist concerns, and how it can be cultivated in light
of psychological research. Traditionally, agape has been defined as unconditional self-sacrifice
for the sake of the other. Feminist theologians have highlighted repeatedly that an ethical
principle of self-sacrifice might not be liberating for groups who have already internalized
pressure to sacrifice their own needs for others. The main research questions are: 1) How may
agape be understood in light of feminist concerns about its traditional interpretations? 2) How
could a Christian community cultivate a form of agape that is responsive to feminist concerns?
In order to answer these questions, the first part of the dissertation examines feminist concerns
regarding discussion of agape, and then uses these concerns as a lens for analysing four themes
in contemporary accounts of agape: community, care, humility, and mentalization.
Välbefinnande och Kognitiv Prestation : En experimentell studie om positiv sinnesstämning främjar kreativitet och flexibelt tänkande
The purpose of the study was to investigate, through an experiment, if positive mood promotes creativity and flexible thinking. Participants were a total of 93 college students. The main hypothesis was that subjects induced with positive mood would perform better than subjects induced with negative mood, at a test reflecting creativity. To further explore the implications of priming (subliminal manipulated moods), a neutral control group was included. The cognitive test used in the study was Duncker´s The Candle Problem, a test which aims to get the subjects to apply flexible and creative thinking.
Svängda hyllor - den raka vägen till en attraktiv butik? En kvantitativ studie om konkava hyllors effekter på kundens perception av sortimentet, upplevelse av butiksmiljön och köpbeteende.
Due to the harsh competition among Swedish food retailers, in-store marketing is a crucial component in the stores marketing strategy. In an attempt to differentiate among its competitors, COOP Sweden has begun to use concave store shelves. Although the food retailing industry is one of the most studied, no research has been conducted on the concave store shelves. The objective of this study is to describe how these shelves effect the customer perception of the assortment, their experience of the store environment and their buying behavior. An S-O-R framework is used as an overall basis in order to outline the effects investigated in this paper.
Skolans information om alkohol och trafik : En utvärdering av rollspelet Leka med Döden för påverkan av skolungdomars attityder till alkohol och trafik
In this study I have investigated how role playing may change young students´ attitudes and behavior. According to the Swedish National Agency for Education´s governing document, Läroplanen för de frivilliga skolformerna, 1994, the principals at Swedish schools are required to inform students about the risks connected with alcohol and traffic. Scientists bring to our attention the need for emotional information to change attitudes and behaviors. The Historical Wine- and Sprits Museum in Stockholm has arranged a role play that gives emotional information to school students in order to affect their attitudes towards drunk driving. My study is a qualitative examination of this role play.
Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark
In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

Inventering av vecklare i Svenska äppelodlingar
Over the last couple of years, growers, researchers, advisors and plant protection companies have noticed increasing problems with tortricids in Swedish apple orchards. Since the insecticide Gusathion (azinphosmethyl) has been banned (end of 2008; KemI 2008), a further increase of tortricid populations can be expected. In order to get a picture of species composition and population densities among the tortricids, an inventory of seven species, Adoxophyes orana, Archips podana, Archips rosana, Cydia pomonella, Hedya nubiferana, Pandemis heparana and Spilonota ocellana was made in 11 orchards in southern Sweden (Skåne) in 2008. Population densities were estimated by bud sampling (April 20-25), pheromone trapping (May 5-September 22) and assessment of fruit damage (September 9-12). In all orchards A.
