  • Hvordan få flere til å bli igjen? En studie om hvordan man kan motivere flere unge til å bli igjen på bygda for å arbeide 

    Olsen, Michelle Kristiansen (Master thesis; Mastergradsoppgave, 2018-05-31)
    Fraflytting og sentralisering er ikke ukjente fenomener, og som vi vet er det enormt mange unge som flytter fra bygda til byen når de er ferdig med videregående skole. Formålet med denne studien var derfor å se på hva som kunne motivere unge til å bli igjen på bygda for å arbeide, i stedet for å flytte til storbyen. Valg av case falt på Sortland, en bygd i Nordland hvor handel står som ...

  • Keep on fighting: The dynamics of head starts in all-pay auctions 

    Clark, Derek J.; Nilssen, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-22)
    We investigate a model of a series of contests in which a contestant's past and present success gives a head start over a rival in the future. How this advantage from winning affects contestants' efforts, whether the laggard gives up or keeps on fighting, and how the head start develops over time, are key issues. We find that the expected effort of the laggard will always be higher than the rival ...
