  4. 3. Opening the Black Box

    Kandidat-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Mårten Liljeblad; Sebastian Hjorth; Axel Jidorf; [2022]
    Nyckelord :Initial Public Offering; Underwriting fee; IPO Gross Proceeds; Bookrunner; Nasdaq First North; Underwriter reputation; Venture capital; Offering size; Business and Economics;

    Sammanfattning : Purpose The purpose of this study is to examine how underwriter reputation, VC-backing and offering size affected the fees paid to underwriters on Nasdaq First North during the time period 01-01-2021 to 31-12-2021. In doing so, the study aims to contribute to a more comprehensive theoretical understanding of the entire cost image associated with going public. LÄS MER

  5. 4. A Root Sum of Squares approach for determining uncertainties in three different ways of characterizing a surface temperature for a Hot Box Setup : With added U-value calculations and incorporated uncertainties

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik
