Forecasting foreign exchange rates and financial asset prices in general is a hard task. The best model has often been shown to be a simple random walk, which implies that the price movements are unpredictable. In this thesis models that have been somewhat successful in the past are developed and investigated for different forecasting horizons. The aim is to find models that significantly dominate

Transitional economies tend to see trade liberalization and capital reforms hand in hand. The main goal or aim for lawmakers is to maximize welfare effects when bringing trade and capital reforms within an economy. A nation gets greater access to international financial markets, which in turn attracts inflow of investments within economy. This newfound inflow of investments can also be attributed

One of the topics that has generated discussions and focuses on demographic theory is undoubtedly the treatment of fertility rates, another important number of studies have incorporated different methods for measuring behaviors in count data, such as Poisson models, also used in the present document. On the other hand, by using panel data, we estimate a random effects model and evaluate the dete

The paper examines the extent to which role-based access control is used within organizations to control and assign access rights to users. Furthermore, this paper investigates whether organizations are aware of security risks that arise when users are assigned too many or incorrect access rights and the steps they take to reduce the problem. The survey was conducted through the collection of qual

This paper discusses what the transfer of white trash from the US to Sweden means; how did it happen, why did it happen and what are the swedish interpretation of the concept? The concept of white trash include both pride and dirt; it frames an anomaly composed of bad taste and a dangerous body. But it is also a subject of creating identities and making fun. The journey to Sweden should be seen in

Whether a law implementation can be said to have had an social impact is largely dependent on if the law in question effected the minds of the people it was tasked to govern. Previous research of successful implementation of laws identify the importance of certain conditions to be present if a law is to be termed “successful”. A law implementation that has been recognized as having had a marked ef

This paper investigates the characteristics and history of value added taxes. Many previous studies have focused on the theoretical implications of value added taxes; this paper differs in the method used as well as the phrasing of research question. This paper seeks out to answer whether a redesign of the current Value Added Tax system in Sweden could be a Pareto improvement. It looks at relevant

In this thesis a method for decomposing QCD colour structures into multiplet bases is described. The method is applicable for any number of gluons and quarks. To achieve the decomposition requires the knowledge of group theoretical weights, so-called Wigner 3j and 6j coefficients. The number of required coefficients have been calculated for up to 12 external gluons, and been shown to scale well in

The big risk topic in recent years, in the nancial industry, has been about capital requirements. The nancial crisis in 2008 displayed several shortcoming regarding weak capital buers in banks. After that crisis big eorts have made sure that the capital buers have been improved drastically over Europe. Now another issue is starting to worry nancial regulators in Europe regarding the quality of ban

In this thesis, we study the problem of predicting users' media preferences based on their, as well as other users' historical rating data. The model used is that a user's rating for an item can be explained by a sum of bias terms and an inner product between two vectors in some multidimensional feature space that is specic to the product domain. This model is tted using a stochastic d

Abstract The long-term aim of this project was to develop synbiotic drinks presenting food supplements with beneficial effects on human health. A synbiotic consists of a combination of probiotic bacteria and one or more prebiotics. For the part of the project that was covered by this Master thesis, a probiotic strain, Lactobacillus plantarum F44 and a prebiotic galactooligosaccharide (GOS) were t

I det mångkulturella samhälle Sverige idag är, har dagstidningar en viktig roll i att spegla detta samhälle på ett korrekt sätt. Vi har intresserat oss för hur personer med annan etnicitet presenteras och hur ämnen som immigration och integration framställs i Sydsvenskan. Vi vill undersöka hur representationen ser ut och om den kan tänkas vara en bidragande orsak till vardagens problem, såsom disk

Att inte få sina anspråk erkända på grund av brist på överensstämmelse med samhälleliga förväntningar är ett problem som står i rampljuset i denna studie. Studiens empiriska utgångspunkt är hämtad ur tv-serien ”Svenska till varje pris”, vilken visar åtta människor som deltar i en utbildning i ”Svenska för invandrare” (Sfi) med målet att slutföra den på åtta veckor. Syftet med uppsatsen är att unde

Med utgångspunkt i den monogaminorm som är så gott som allrådande i det moderna samhället är syftet med denna undersökning att ta reda på hur intimitet skapas i relationer som går bortom denna norm. Sex personer som har erfarenhet av icke-monogama relationer intervjuas för att synliggöra hur överenskommelser, förväntningar och gränsdragningar bidrar till skapande av närhet och intimitet. Dessa ber

Environmental monitoring using bioindicators is a valuable tool in quantifying and assessing metal pollution in the aquatic environment. In this study, I have analyzed monitoring data on metals in blue mussels (Mytilus Edulis) from the Öresund in Landskrona, Sweden. Comparisons with previous monitoring studies from the area show elevated concentrations of several metals, including copper (Cu), lea

China's tourism industry has only developed after its opening-up in 1978. However, the inbound and outbound tourism is more often researched than the domestic tourism industry. Therefore, this research provides an analysis of the domestic travel behaviour of the Chinese between the ages of 20-35. Furthermore, the analysis is based on a survey, which was conducted amongst that age group. The ai

Entrepreneurial orientation (EO) can be defined as strategic processes encouraging entrepreneurial actions to support businesses in recognizing and exploiting new opportunities. Previous studies have shown that businesses with higher levels of EO, characterized through actions that are innovative, proactive and risk-affine, perform better than the ones that lack such orientation. Therefore, EO is

I och med att globaliseringen ständigt ökar, så ökar även antalet multinationella företag (MNF), som i sin tur ökar antalet gränsöverskridande interna transaktioner. De globala effekterna av manipulerad internprissättning har länge varit ett välkänt fenomen och metoderna för att finna rätt internpris har utvecklats under åren. Den rådande principen för att hantera detta är att transaktionerna skal

Existing economic literature demonstrates that gender-oriented conditional cash transfer programs modify women’s economic opportunities and consequently, their power status within their households. Nonetheless, these studies are not conclusive in determining whether or not this improved position of power has the potential to significantly alter the chances of women to suffer from intimate partner
