Att bedöma och betygssätta företags kreditvärdighet är en stor och vinstbringande marknad. Ett företags kreditbetyg har visat sig ha stort inflytande när t ex lånevillkor behandlas. Detta ställer höga krav på kreditvärderingsföretagens förmåga att leverera korrekta analyser. Såväl långivare som investerare reagerar på ett ändrat kreditbetyg, vilket ger direkta effekter på det företag som betygssät

Sri Lanka has experienced a double-digit unemployment rate for almost three decades.

Knowledge is today considered to be a critical factor for organisations to survive within an increasingly competitive market. This has resulted in the fact that effective management of information and knowledge has become of crucial importance for companies.

This thesis gives a contribution to strategy-proof social choice theory, in which one investigates to what extent there exist voting procedures that never can be manipulated in the sense that some voter by misrepresentation of his preferences can change the outcome of the voting and obtain an alternative he prefers to that honest voting would give. When exactly one element should be elected from a

The legal courts in Sweden have developed a case law wherein the application criteria for being eligible to acquire unemployment insurance have become strict and rigid. This is in particular true when it comes to professional athletes who cannot make a living on their athlete wage. It is the 9th to 11th section of the Swedish Law (1998:238) on Unemployment Insurance that set the determinants for w

Fair trade har vuxit fram med en otrolig fart de sista åren och frågan är hur det påverkar producenterna, om det existerar något sådant som rättvis handel och om marknaden kan fortsätta växa? För att diskutera dessa frågor presenteras nationalekonomiska modeller, argument för och emot fair trade samt ett antal fallstudier i ämnet. De modeller som tas upp är H-O modellen tillsammans med Stolper-Sam

Då allt fler mobiltelefoner med integrerad digitalkamera sprider ut sig bland allmänheten skapas ökade möjligheter för många människor att spontant kunna fotografera sina omgivningar. Kameratelefonen är dessutom svår att skilja från en vanlig mobiltelefon, vilket gör att en person kanske inte ens vet om att denne blir fotograferad. Genom kameratelefonernas kommunikationsteknik kan sedan dessa bild

Denna uppsats grundar sig i en kvalitativ studie som behandlat fallgropar som återfinns inom projektstyrningen i IT-projekt. Att IT-projekt ofta framställs som över tid och budget och därmed som misslyckade var ett intressant fenomen som vi ville titta närmare på. Vårt fokus låg på själva projektstyrningen av projektet och av den anledningen uteslöts faktorer som utvecklingsmetod eller designaspek

Through WTO membership, a large number of countries are parties to the Agreement on Trade-Related Aspects of Intellectual Property Rights, also known as TRIPs. The strongest form of IP protection is the patent, which grants a number of valuable exclusive rights when the criteria for patentability have been met. Patents are often claimed to be a means for inventors to regain the expenses they may h

Syftet med uppsatsen är att undersöka olika modellers förmåga att prognostisera den systematiska samvariationen mellan Affärsvärldens branschindex. Med regressionsanalys undersöks systematisk kovarians på den svenska aktiemarknaden under perioden 1997 – 2006. Först skattas branschindexens känslighet för olika riskfaktorer, skattningarna används för att skapa en varians-kovariansmatris. Utvärdering
