    Sammanfattning : In regions with cold climates, a layer of ice often forms on vehicle windshields, whichobstructs the driver’s view. To address this issue, vehicles are equipped with internal defrosters. However, at Scania, the evaluation of defroster design performancecurrently relies on time-consuming and costly physical testing. LÄS MER

  5. 24. Market Performance in the Nordic Electricity Market: An Analysis of Market Power during Energy Market Turbulence

    Kandidat-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Simon Persson; [2023]
    Nyckelord :Business and Economics;

    Sammanfattning : This paper analyzes the existence of market power on the Nordic electricity market between 2018-2022, and if the energy market turbulence caused by covid-19, and later deepened following the war in Ukraine affected producers' bidding behavior. Market power was tested using Cournot assumptions to see if producers withheld output strategically when demand was more inelastic. LÄS MER
