dc.description.abstractPrice changes in any market are essentially due to shifts in supply relative to demand. In a global market there can be several simultaneous supply and demand shifts in different geographical locations, all affecting prices to different extents. This dissertation focuses on procedures for measuring such shifts and their relative effects on prices by looking at the global market for farmed salmon in the period between 2002 and 2011. Farmed salmon is a relatively homogeneous, globally traded product whose market size has burgeoned over the last 30 years. The first paper determines the magnitude of the shifts in annual demand across all salmon-importing regions. Results indicate that demand varies considerably between years and regions and does not appear to follow a smooth trend - as usually assumed in empirical demand analysis. The second paper uses the same approach to determine the size of annual regional supply and demand shifts from exporting and importing regions. The impacts of these shifts on prices are determined through an Equilibrium Displacement Model. This allows the decomposition of annual price movements into the effects of regional supply and demand shifts. We find large variation in supply and demand shifts and price impacts between regions and within regions over time. The third paper extends the procedure of the first. We disentangle the impacts from income growth and price changes in substitute products from the total demand shift. The remaining, residual shift in demand is due to other, unknown or omitted factors. Results indicate demand shifts due to unknown factors account for a large portion of total demand growth in all salmon-consuming regions and residual demand growth is not smooth in any region.en

dc.description.popularabstractJeg måler endringer i tilbud og etterspørsel og effekter på pris i det globale markedet for oppdrettslaks. Mellom 2002 og 2011 har det vært stor variasjon i etterspørselsveksten mellom regioner, og innad i hver region. Russland og Brazil har hatt en sterk etterspørselsvekst, mens etterspørselen i tradisjonelt viktige markeder som USA og Japan har stagnert. Inntektsendringer og prisendringer på konkurrerende produkter forklarer noe av etterspørselsendringene, men for de fleste regioner er over 50 prosent av endringene forårsaket av ukjente faktorer. Tilbudsøkning fra Norge har hatt størst negativ effekt på lakseprisen, mens etterspørselsvekst i EU har hatt størst positiv effekt. Den store variasjonen i både tilbud og etterspørsel i de fleste regioner forklarer hvorfor lakseprisen varierer så mye. Metodene som er anvendt i denne avhandlingen kan være nyttige verktøy for å avgjøre årsakene til prisendringer i andre markeder med ustabile priser.en
