    Sammanfattning : Consequences of within population variation have recently attracted an increased interest in evolutionary ecology research. Theoretical models suggest important population-level consequences, but many of these predictions still remain to be tested. LÄS MER

  4. 13. Essays on R&D and Growth

    Författare :Henrik Braconier; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; International commerce; Technology; Scale effects; Innovation; Imitation; R D; Endogenous Growth; Internationell ekonomi;

    Sammanfattning : The purpose of this study is to analyze some aspects of the relationship between R&D and economic growth. In Chapter 2 we analyze how costly imitation may be incorporated into an R&D-driven endogenous growth model. In the model, optimizing firms allocate resources to innovation or imitation. LÄS MER
