Vilken påverkan har arbetsmarknadens institutioner på arbetslöshet? : en ekonometrisk jämförande studie av kapitalstock och arbetsmarknadsinstitutioner

This papers? objective is to examine the effects that labour market institutions (LMI) have on the unemployment in the short- and the medium run throughout the new Keynesian NAIRU theory, but also to make a comparison with the postkeynesian capital stocks? effect on the unemployment. Thus, it is this papers? main objective to study the economic effects that LMI, capital accumulation and varied macroeconomic shocks might have on unemployment. The paper uses econometric regression models as a methodological benchmark in order to estimate each independent variable?s level of significance and to approximate the effect each have on the dependent variable.

Vilka parametrar påverkar lönsamheten för hotellföretag? - en kvantitativ studie av RevPAR i Göteborg

Denna kandidatuppsats har analyserat interna parametrar som påverkarlönsamhetsmåttet RevPAR (Revenue Per Available Room/intäkt per tillgängligt rum)för hotellföretag i staden Göteborg. Syftet är att få en djupare förståelse för vilkainterna parametrar som påverkar lönsamhet, samt hur och i vilken utsträckning.Studien baserades på en teoretisk referensram bestående av ?Resource-based view?och flertal tidigare studier inom ämnet. Det senare ledde till ett val av tio internaparametrar, med tillhörande hypoteser för undersökningen. Empirin framställdes avinsamlade värden från ett urval på 34 hotellföretag.

Silikonprodukter för vardagsbruk

The aim of this thesis is to practice the theoretical methods that are concerned during the product development process of two new products. The theoretical concepts that embody the two products are created out of a product specification which is given by a commissioner with a private interest. The primary tasks of the design of the concepts are aimed on the products shape, which is to be created as a flexible structure by using silicon rubber as material.The storage box is a further development of the already known food storage box, or lunch box, which is common used in consumer kitchens. The main idea is to design a flexible product by using silicone rubber. It will able the storage box to be compressed when it is not used, be storage friendly and not consume more space than necessary in a storage compartment.

Förklarande faktorer bakom statsobligationsspread mellan USA och Tyskland

Det här kandidatexamensarbetet inom matematisk statistik och industriell ekonomi undersöker förklarande faktorer bakom ränteskillnad, så kallad spread, mellan amerikanska och tyska statsobligationer. De obligationer som undersöks har en löptid på fem respektive tio år. Den huvudsakliga analysen görs genom multipel linjär regression. Regressionsmodellering av statsobligationsspread är vanligt förekommande i bankvärlden och det här kandidatexamensarbetet kan utgöra en grund för vidare modellering och förbättring av befintliga modeller. Problemformuleringen och arbetsupplägget har utformats i samarbete med en svensk bank, som inte nämns vid namn på grund av sekretesskäl.Kandidatexamensarbetet består av två huvuddelar.

Kommunfullmäktigeledamöters sociala representation -en fallstudie i tre svenska kommuner av kön, ålder och etnicitet

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

Arbetslöshet bland utrikes födda på den svenska arbetsmarknaden : En empirisk analys av vilka kommunala faktorer som kan påverka den höga arbetslösheten bland utrikesfödda

Unemployment amongst Swedish citizens is higher within the group which falls under the designation foreign-born. The aim of this thesis is to examine which municipal factors that can explain the differences in unemployment amongst foreign-born relative to native born.The empirical models are examined with both cross-sectional data for the year of 2010 and panel data for the years of 2002-2012. The examination is implemented through a linear regression analysis of the type Ordinary Least Squares (OLS) and Fixed Effect regressions. A theory section will be presented where the theory on Non-Accelerating Inflation Rate (NAIRU), theories on discrimination and country-specific human capital are illustrated.The result from the cross-sectional data shows that the amount of foreign-born, the level of foreign-born immigrated from Nordic countries have a significant negative effect on unemployment amongst foreign-born. The general unemployment shows a significant positive effect on the unemployment amongst foreign-born.

Ventilhus för salivsug i dentalutrustning

The purpose of this work is to find out if the suctionvalve to the salivaejector for dental equipment in a simple way can be improved or if a new design is needed. The result of the examination of the suctionvalve shows that the friction between the piston and the seal is high and that this causes the valve in a few cases sheaves. The study concluded that only small changes in material or detail, improve the component..

Driftoptimering av Luleås fjärrvärmesystem

Produktionen och distributionen av fjärrvärme i Luleå kommun sköts av två företag, LuleKraft AB och Luleå Energi AB. Under 2011 utökades samarbetet företagen emellan, med bland annat gemensam driftspersonal. Detta ger förutsättning för ett mer anpassat och optimerat produktionssätt. Med detta som bakgrund skapades en modell över fjärrvärmenätet och tillhörande anläggningar, för att kunna skapa riktilinjer för effektiv produktion vid olika driftförhållanden. Viktiga komponenter för systemet är? Lulekraft - ett kraftvärmeverk vilket eldar processgaser från SSAB och olja för att producera fjärrvärme och el? Fjärrvärmenätet - 42 mil långa ledningar förser i princip hela Luleå kommun med fjärrvärme? Hetvattencentraler - när LuleKraft inte räcker till för att täcka fjärrvärmebehovet finns möjligheten att använda dessa där bränslet är processgaser, olja, pellets eller elFjärrvärmenätet och hetvattencentralerna ägs av Luleå Energi AB men hela systemets drift sköts av personal på LuleKraft.

Flödeslogistik vid Laponia Hotel

The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.

Effect of cow traffic system on cow performance and AMS capacity

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

Vilka fattiga är fattigast? : fattigdomsfokusering av det svenska frivilligorganisations-biståndet jämfört med det totala svenska biståndet

 This paper discusses whether the allocation of Swedish aid is dependent on absolute or relative poverty, and whether there is any difference in this respect between ODA and aid distributed through officially funded NGO?s. Given the Millennium Development Goals, and their overarching goal of halving extreme poverty by 2015, we should expect the aid allocation to be determined by absolute rather than relative poverty. We use OLS to estimate multiple linear regressions. We find that Swedish ODA has an absolute poverty focus, while the Swedish NGO aid rather seems to be concentrated on relative poverty. .

Flexibel isolering av fönster för att minska energiförluster

The first part of this essay is about a single-family house that we have planned and projected. Thesecond part is a deeper study in ways to further insulate windows when they are not in use.In the first part the building?s design and its most important construction elements are described.The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity)are reported so that one can in principle start construction of the house. In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south.
