UndervaĢrdering vid boĢrsnotering? : En studie om innovativa foĢretag och underprissaĢttning
Forskning redogoĢr foĢr att foĢretag som boĢrsnoteras i genomsnitt underprissaĢtts. Syftet med studien var att undersoĢka skillnaden i underprissaĢttning mellan innovativa- och icke-innovativa foĢretag i samband med boĢrsnoteringar paĢ marknadsplatserna Aktietorget och StockholmsboĢrsen. Populationen bestod av 258 foĢretag som boĢrsnoterades mellan 1 januari 2006 och 10 april 2018. Studien tog stoĢd i teorin om informationsasymmetri samt signalteorin foĢr att foĢrklara underprissaĢttningen hos foĢretagen. Sambanden undersoĢktes genom en OLS- regression bestaĢende av en enkel- och en multipel regression. Resultatet visade att innovativa foĢretag underprissatts mer aĢn icke-innovativa foĢretag och var statistiskt signifikant foĢr den enkla regressionen. Studiens resultat tolkades delvis i enlighet med tidigare forskning och indikerade att informationsasymmetrin var hoĢgre foĢr innovativa foĢretag.
On-line Powerplant Control using Near-InfraRed Spectroscopy : OPtiC-NIRS, REPORT 2021:746
Near InfraRed Spectroscopy (NIRS) offers rapid on-line analysis of biomass feedstocks and can be utilized for process control of biomass- based combined heat and power plants. Within the OPtiC-NIRS project we have carried out a full-scale on-site testing of different NIRS for online powerplant control at the facilities of MaĢlarenergi and Eskilstuna StraĢngnaĢs Energi och MiljoĢ.Ā The project has been focused on developing and testing robust NIRS soft-sensors for fuel higher heating value and composition (incl. moisture, components such as recycle wood and glass, different type of plastics and ash) and combining them with dynamic models for on-line feed-forward process monitoring and control. Expected benefits include reduced risk of agglomeration and pollutant emissions formation as well as improved production control. A longer-term potential and ambition is to be able to identify the fossil content in municipal waste fuel, which can hopefully be addressed in a follow-up study.Ā These are the results and conclusions of a project, which is part of a research programme run by Energiforsk.
