Most dictionaries give the meaning "Economy" for the word "Wirtschaft" (and "Economical science" for the word "Wirtschaftswissenschaft").
In English speaking universities we have two separate fields namely "Business Management" and "Economics" (which cover totally different topics). But in German speaking universities they both seem to be referred as "Wirtschaftswissenschaft" (possibly with BWL and VWL branches?).
So what is the difference between the words "Wirtschaftswissenschaft" and "Ökonomie" ? Is the first one equal to "Management" and the second one equal to the "Economical science"?
