This paper investigates whether inflation series are mean-reverting. Traditional unit root tests (ADF and KPSS tests) are conducted in the paper. These tests indicate that inflation contains a unit root. It is however well-known that traditional unit root tests have difficulties to distinguish between a unit root process and a fractionally integrated process. Hence, in this thesis, fractional inte

In this essay a four stage GJR-GARCH(1,1) model is applied to test the presence of both return and volatility spillover to the European market from the oil market. The GJR-GARCH-model allow for asymmetric effects to be present in the country specific stock market. This four step model is applied to eight European countries and allow for spillover effects from oil market, US market and European mar

Problemområde: Trots att radio är ett av de medier som vi ägnar mest tid åt idag finns det relativt lite forskning inom området. Det finns alltså utrymme att lyfta fram ett antal viktiga aspekter och problem inom detta ämne. Jag vill belysa hur ekonomiska tankesätt påverkar radions innehåll. Syfte: Syftet är att kartlägga och förstå hur den svenska radiomarknaden präglad av kommersiell radio förh

It is during a child’s second year that the rate of word learning increases drastically and they start to pay more attention to the property of shape when categorizing new objects. The present study set out to investigate the relationship between productive vocabulary size and the shape bias when children learn novel words. In order to better understand the neural mechanisms behind this process, e

The issue of a housing bubble has been abundantly debated in Sweden. In this thesis, we investigate whether the current state of the Swedish housing market is comparable to the recent US ‘housing bubble’. Growth rates of house prices can vary greatly between different regions, which shows the need for analysis of house prices on a regional level. Using a panel consisting of 22 Swedish counties and

As a transition economy, China faces the reality of shortage of innovation resources and unbalanced allocation of innovation resources among regions when operating innovation activities. In order to solve these two problems, China needs to make efforts in increasing innovation efficiency and narrowing disparities between eastern regions and other regions. Among them, central regions are the area t

Integration programs are important and at the same time controversial parts of an immigration policy. This paper contributes to this debate by evaluating the effectiveness of German language trainings for immigrants with respect to their labor market performance. To allow for possible sample selection bias, the propensity score matching method is applied. This method matches treated and control pe

Denna studie behandlar prognostisering av månadsinflation och utgörs av en jämfö-relse mellan en skattningsmetod som enbart använder data för den specifika situationen – en klassisk metod – och en skattningsmetod som använder både datan och annan kunskap – en bayesiansk metod. Bägge skattningsmetoderna används på en enkel modell för månadsinflation i Sverige, Norge, Eurozonen, Storbritannien, JapaThis paper covers forecasting of monthly inflation and consists of a comparison between an estimation method solely based on data – a classical method – and an estimation method based on that data and other knowledge – a Bayesian method. Both methods are applied to a simple model of monthly inflation in Sweden, Norway, the Euro area, Great Britain, Japan and the US, and the comparison is performed

Flyktiga organiska föreningar som släpps ut från växter (BVOC- Biogenic volatile organic compounds) kan ha en stor påverkan på atmosfärisk kemi genom reaktioner som leder till ökad eller minskad ozonproduktion, och genom att de kan vara ett förstadium till aerosoler. De vanligaste flyktiga organiska föreningarna är isopren (2-metyl, 1,3-butadien) och dess derivat, terpener och terpenoider (isoprenBiogenic volatile organic compounds (BVOCs) can have a large affect on atmospheric chemistry by the production or degradation of ozone and by acting as precursors to secondary organic aerosols (SOA). The most common BVOCs are isoprene and its derivatives, terpenes and terpenoids (isoprenoids). These are used by the plant in cell membranes and as steroids, but are also a means of communication and

Climate and vegetation growth of an area are interrelated processes; both take place on small to global scales. However, climate change and variability impacts on vegetation in most places in the world including Tanzania is of great concern since vegetation supports many socio-economic sectors, and plays a crucial role in atmospheric greenhouse gas moderation. This study aims at investigating the

This paper aims to illuminate the strategies of international and national drug control. As globalization affects the global drug problem and the possibilities of controlling the same, an effective drug control at the international level is highly important. The Swedish drug policy is considered good through international standards but it is based on restrictive policies aiming towards a drug free

Under de senaste decennierna har det blivit allt tydligare att den omfattande användningen av fossila bränslen är dåligt för miljön. I och med att kunskapen om hur fossila bränslen påverkar miljön har ökat, så har också intresset för alternativa bränslen ökat. Etanol är ett förnyelsebart bränsle som framställs av biomassa och användningen av etanol har ökat under de senaste 40 åren. Etanol ger minDuring the last decades, it has become increasingly clear that the extensive use of fossil fuels may severely threaten the environment. As the awareness of negative environmental impacts of fossil fuels has increased, the interest of alternative fuel sources has developed. Ethanol is a renewable fuel made from biomass that has attracted growing attention during the last 40 years. Ethanol has lower

På den Indokinesiska halvön ligger Mekongflodens avrinningsområde. De senaste årtiondena har Kina, som innehar den nordligaste delen av flodbassängen, startat ett omfattande vattenkraftsprojekt på flodens huvudfåra. Åtta mycket stora dammar är planerade varav tre redan är byggda. Länderna som ligger nedströms från Kina, nämligen Laos, Kambodja och Vietnam har på senare tid också beslutat att byggaThe Mekong River catchment on the Indochinese peninsula in Southeast Asia is currently one of the world’s most active regions in terms of hydropower planning and development. In recent decades China has launched a hydropower plan comprising eight large dams on the main stream river in the upper part of the catchment. Three dams have already been built and now also the countries in the lower basin,

Populärvetenskaplig sammanfattning: Kvävecykeln är betydelsefull i ett globalt perspektiv eftersom den inverkar både på klimatet och olika ekosystemsprocesser. Den kan med andra ord beskrivas som kvävets kretslopp som beskriver de kemiska, fysiologiska, biologiska och geologiska processerna som sker i naturen. Dikväveoxid är en stark växthusgas och inverkar på klimatet då den precis som koldioxid The nitrogen cycle is included in the biogeochemical cycles that connect all the organisms in one giant ecosystem, the biosphere. The nitrogen cycle is important both in a global perspective where the greenhouse gas N2O affects the climate and in a local perspective where it controls different processes in ecosystems. The availability of nutrients also have a great influence on all aquatic ecosyst

Eye tracking, the direct measurement of eye movements, is a method suitable for studying cognitive processes in detail, and has been used for studies of both human and nonhuman subjects. It provides an opportunity to study human and animals under similar conditions, using the same apparatus, and can therefore be a useful tool in comparative studies. Unfortunately this possibility is seldom utilize

Abstract The aim of this paper was to find out whether Swedes with a good knowledge of the Italian language were capable of laughing and reacting at the jokes of the Italian comedian Antonio Albanese through his fictional character, Cetto La Qualunque. The focusing point was to determine which linguistic features alongside non-linguistic features (i.e., body language and mimic above all), would

Syftet med denna uppsats var att genom en explorativ undersökning titta efter skillnader mellan den serbiska och svenska kulturen i Sverige och Serbien i en arbetsrelaterad kontext och på vilket sätt/hur dessa i så fall uppenbarar sig. En kvalitativ, emergent design användes för undersökningen, där 12 respondenter deltog. Studien har en fenomenologisk ansats, där självrapporter använts. Resultatet

Icelandic authorities implemented capital controls in October 2008, in a response to the global financial crisis and to prevent outflow of foreign reserves. This was done to protect the Icelandic krona from depreciating and to gain monetary autonomy. However, the operational activity of the pension funds in Iceland has been affected by this policy change, as the funds have been missing out on fore

The aim of this thesis is to study the role of house prices in influencing the effect of monetary policy shocks on private consumption in five EMU member states during the period 1995Q1-2010Q4. The role of house prices may be increasingly important in effecting private consumption possibilities due to the deregulations of mortgage markets in many countries in recent years and the increasing availa
