Det idag väldigt populära riskmåttet Value-at-Risk (VaR) kan beräknas på många olika sätt. En metod som använder sig av extremvärdesteori (EVT) för att estimera VaR utvecklades under 1990-talet som ett alternativ till de traditionella VaR metoderna. EVT fokuserar på fördelningens svans, eftersom det är här de extrema observationerna uppträder. I denna studie undersöker vi hur framgångsrik extremvärdesmetoden är när det kommer till att estimera VaR för råvaror, en typ av tillgång som karakteriseras av att vara extremt volatil och därmed speciellt svår att riskbedöma. Våra resultat pekar på att extremvärdesteorin erbjuder ett intressant alternativ när man önskar att estimera VaR för volatila råvaror.

The rise in prevalence and severity of obesity and related diseases imposes increasing costs on society. The objective of this thesis is to discuss and estimate the possible effects of a so-called fat tax as a tool for minimizing these costs. Two alternatives for differentiation of the value-added tax (VAT) on food are compared. The first alternative is an increase of the VAT levied on food containing saturated fatty acids. The second alternative is a subsidy on fruit and vegetables in the form of a VAT at zero percent, instead of today?s twelve percent.

The aim ofthis study was to examine how economic growth affects the level of democracy inauthoritarian states. Some of these states have experienced high economicgrowth. However, one can discuss how it affects the country?s democratization-process.For that reason this study was needed to contribute to a clarification of howeconomic growth can affect authoritarian rule and democratization. This wasdone through an examination of the development in China.

The aim of this thesis is to study the cause of Egypt´s failed development of the transition to democracy and vice versa, the reason why Turkey succeeded in democratic transition. Thesis methodology is a comparative analysis between design units Egypt and Turkey. Thus, the most similar design used in the investigation.European Commission began in 1998 to review Turkey´s political and economic reforms to fulfil the Copenhagen criteria. 2005 began negotiations on a Turkish- EU membership. U.S and Egypt have enjoyed close economic, security and democratic cooperation since 1975.

Abstract In my work, I have tried to define and clarify the conception of sustainability seen from my perspective as a landscape architect. With a basis in literature studies, I have analysed and commented on different applications, contents and meanings of sustainability and endurance. This compilation is based on how a number of writers, researchers and authorities consider the importance of integrating ecological, social and economic aspects of sustainability in city planning. My perspective has mainly been founded on the anthologies and compilations from the 80´s and 90´s where Per G. Berg and Björn Malbert acted as editors.

Social hållbarhet är ett högaktuellt ämne. Delegationen för hållbara städer presenterade år 2012 sin slutrapport och bara ett år senare presenterade Malmökommissionen sin slutrapport för ett social hållbart Malmö. Syftet med uppsatsen är att bredda kunskapen om social konsekvensbeskrivning samt att undersöka dess potentiella effekt på social hållbarhet, eftersom det är av största vikt att hitta konkreta arbetssätt för att uppnå ökad social hållbarhet. Genom en litteraturstudie undersöks i uppsatsens första del vad begreppet social konsekvensbeskrivning har för bakgrund, varför det förespråkas, hur en metod för genomförande skulle kunna se ut samt vilka utmaningar som finns. I uppsatsens andra del studeras tre artiklar som utvärderat effekten av att utföra social konsekvensbeskrivning. Litteraturstudiet resulterar i slutsatsen att social konsekvensbeskrivning har stor effekt på social hållbarhet, på flera olika sätt. Trots att metoden medför en hel del komplexa frågor att förhålla sig till finns det därmed god anledning att utveckla arbetet med social konsekvensbeskrivning, för att vi tillsammans ska nå en mer socialt hållbar framtid..

In September of year 2006, a young boy was brutally killed by a girl, age sixteen, in Örebro, Sweden. Girlgangs became a frequent subject in media. Professionals? working with adolescents claims that girlgangs notis an existing phenomena in Sweden as it is in for example in the United States. The aim of this thesis was to investigate if teenage girls in Sweden have a tendency to join gangs as they do in the United States.

I denna uppsats undersöks om det förekommer fiskal illusion i det svenska pensionssystemet. Fiskal illusion innebär att en felaktig bild av sambandet mellan kostnader och förmåner i det offentliga systemet uppstått hos medborgarna. Vi utreder vad en sådan illusion kan bero på, vilken betydelser den har och vilka åtgärder som kan vidtas för att minska den. Det framkommer att fiskal illusion existerar och att den till stor del beror på utformningen av pensionsavgifterna. Framförallt är det uppdelningen i en arbetsgivaravgift och en egenavgift, samt att båda betalas in av arbetsgivaren som leder till oklarheter.

The intension of this study is to investigate the interaction between teachers and social workers in two diffrent countys. The study is focused on how teachers act upon suspicions when there are children at risk and what kind of support the teacher gets from social workers. Another importent question is if the teachers know what kind of rules regarding to confidentiality and if it would be better for the pupils if there were no confidentiality.To get answers to my questions, i have interviewed teachers and social workers in both countys.In this study I assume that the power has three dimensions and that there are four levels of interaction.Due to the law about confidentiality the social worker has the power over the teachers. Because the law about confidentiality it is difficult for teachers and social workers to interact.If the teacher want help from social services, she or he must call the social worker because the social worker will not call the teacher. If the social worker want to help the teacher and give her advice, the social worker can do that without breaking confidentiality.

This study has a double purpose. First, it explores and maps out the use of quantitative key indicators in social performance reporting within a microfinance portfolio. This was done on behalf of Storebrand Asset Management, who would like to aggregate and report the social results of their microfinance investments to their customers. The study concludes that the extent of social reporting and types of indicators used varies, meaning that it is hard to aggregate data for use in further reporting. Thus, the work towards the goal of social reporting has only just begun.

The purpose of this thesis is to evaluate and develop a useful theory of human behavior that recognizes the importance of our emotions. The new framework, called the theory of emotional choice, is developed by a holistic method in which results from the fields of psychology, sociology and (neuro-) biology are used to mutually support the conclusions. The theory is distilled into six preliminary points, which are based on the finding that we are not thinking as logical, rational and longsighted as is often assumed. Instead the regular human thinking is suggested to be shortsighted, intuitive and ruled by our emotions and our needs for generality, causality and normality.To demonstrate the usefulness of the new framework, it is used in an analysis of financial bubbles. Additionally, the fields of negotiation, election and ethics are suggested as potentially interesting to analyze with the new theory..

I uppsatsen studerar jag hur Institutet för arbetsmarknadspolitisk utvärdering (IFAU) har följt upp och utvärderat det svenska friårsförsöket. Jag undersöker om deras tillvägagångssätt stämmer överens med hur man teoretiskt bör följa upp och utvärdera arbetsmarknadspolitiska program. Hemström med fleras (2002) ?Att följa upp och utvärdera arbetsmarknadspolitiska program? ligger som huvudsaklig teoretisk grund för studien. IFAU:s uppföljningar av friårsförsöket stämmer till stora delar överens med vad man bör ha med i enkla uppföljningar av program och de har även studerat hur implementeringsprocessen av friårsförsöket har gått till.

Background: The global responsibility for multinational companies is a current matter of subject. Now when the world increasingly is getting globalized, economic growth is created, which brings a bigger demand of responsibility on companies. The leading companies from every industry is often becoming the frame for how the production process works and is therefore exposed to outer pressure which, for example, is coming from consumers and the media. Since consumers at present are more aware of what they are buying and where it comes from, it is important that the companies take social responsibility. We have therefore studied three big companies within the clothing industry to see in witch way they are taking their social responsibility.Purpose: Our purpose was to explore how companies within the clothing industry describe their work with Corporate Social Responsibility, code of conducts and where the incentive behind this work is coming from.Method: We have, through a qualitative study, examined how three large companies work with Corporate Social Responsibility.

The aim of this paper is to study how multiculturalism is expressed in the Swedish labour market policy. The method used for the investigation is a discourse analysis which study social and political processes in the society as created through language. The perspective of the discourse analysis is a social construction that considers that language is a social production created in a discursive way. It produces and reflects social process in the language.By using theories of national identity and multiculturalism we aim to investigate how multiculturalism is expressed in the labour market policy. With this method we aim to analyze the discourse of a political report made 2008 by the current government about integration strategies in Sweden.

Uppsatsen behandlar frågan huruvida dagens Ungern bör kunna betraktas som en konsoliderad demokrati. Frågan utgår ifrån teorin om för att ett lyckat demokratiskt samhälle ska kunna uppnås måste fem dimensioner vara uppfyllda: ett väl fungerande och demokratiskt institutionaliserat civilsamhälle, politiskt samhälle och ekonomiskt samhälle samt en rättstat och statsbyråkrati. Uppsatsen tar tre av dessa samhälleliga arenor i beaktande samt medborgarnas och politikernas attityder och utgår i huvudsak från artiklar, böcker och tidsskrifter. För att åskådliggöra Ungerns utveckling från demokratisk transition till dagens situation har en viss historisk tillbakablick varit nödvändig för att ge perspektiv åt landets sociala, politiska och ekonomiska händelseförlopp..
