Dit document biedt een uitgebreide samenvatting van het vak bedrijfseconomie voor het huidige academiejaar van het schakelprogramma bedrijfskunde. Ik heb alle hoorcolleges en gastcolleges bijgewoond en zorgvuldig gedocumenteerd. Daarnaast zijn alle Wooclap-vragen en oefeningen opgenomen in deze sam...
Good and comprehensive summary, but chapter 8 (Platforms - Investment Analysis) is still missing? I think this still needed to be summarized, would you like to send an up to date version, so please replace the document?

, HOC 1: Fundamenten en marktwerking
1. Kadering van het domein
Wat is bedrijfseconomie?
Economie is de wetenschap van het maken van beslissingen onder de conditie van schaarste.
- Wat is schaarste? Het idee dat middelen niet oneindig zijn en dat daardoor mensen of
organisaties keuzes moeten maken tussen de middelen die hij of zij ter beschikking heeft.
- Welke doelen kunnen dat zijn? Winstdoel (winst maximalisatie), non profit,..
Bedrijfsmanagers richten zich op het beheren van middelen om bepaalde doelen te bereiken
DUS: Bedrijfseconomie is de studie van het efficiënt inzetten van schaarse middelen om
organisatiedoelen te bereiken.
Insteek: het begrip van economische principes is cruciaal voor de effectieve besluitvorming met oog
op doel van het bedrijf, met name winstmaximalisatie en waardevergroting
- Bv. Keuzes over productprijzen, kwaliteit, productiehoeveelheden, HR, etc.
- Bv. Omgaan met acties van concurrerende bedrijven (bv: nieuwe bedrijven die toetreden tot
de markt)
- Bv. Projectevaluatie (Kosten en baten)
- Bv. Marktanalyse
- Bv. Inzetten van technologie
- Bv. Internationaliseringsbeslissingen
Belangrijke concepten voor managers
1. Doelen en beperkingen
Men heeft belang bij het definiëren van duidelijke doelen: welke doelen zijn dit? Hoe gaan we
maximaliseren, wat willen wij maximaliseren,..
Het heeft een grote impact op beslissingen en de modellen die nuttig zijn om in het bedrijf mee om
te gaan. (Bij profit bedrijven: winst, non profit bedrijven: sociale impact, het leveren van goeie
diensten (als het gaat om publieke dienstverlening))
Beperkingen zorgen aan nood voor keuzes (schaarste)
- Bv. Budget
- Bv. Beschikbare technologie
- Bv. 24u in één dag = je werkt hopelijk niet 24 uur in een dag
Verschillende departementen in één organisatie kunnen verschillende doelen hebben
