一天有個年輕人來到王老闆的店裏買了一件禮物,這件禮物成本是18元,標價是21元。結果是這個年輕人掏出100元要買這件禮物,王老闆當時沒有零錢,用那100元向街坊換了100元的零錢,找給年輕人79元,但是街坊後來發現那100元是假鈔,王老闆無奈還了街坊100元。.現在問題是: 王老闆在這次交易中到底損失了多少錢? (Since there are too many versions of this question, I assume this question is the correct one.) 從會計學或經濟學角度去計算,損失都是同樣100元 http://hk.knowledge.yahoo.com/question/question?qid=7012111200304 Garlic2010 “PROUDLY” ANSWERED. (Actually, it’s a piece of ACCOUNTING & ECONOMICS ARTS found from him!!!) 這評論目的在解釋從會計學或經濟學角度去計算,損失都是同樣100元。 http://hk.knowledge.yahoo.com/question/article?qid=6908122800145 I know no accounting but do know a little about economics. I believe it would be amusing to see how you crank up with those numbers, commented by Garlic2010. http://hk.knowledge.yahoo.com/question/article?qid=6912121500348 NOW THIS ARROGANCE CLAIMS HE KNOWS NOTHING ABOUT ACCOUNTING BUT LITTLE KNOWLEDGE OF ECONOMICS. If he claims he doesn’t know accounting and knows little bit of economics, how can he proudly say this: 從會計學或經濟學角度去計算, 損失都是同樣100元? YOU ARE SHAME, OUR RECLUSIVE ONLINE ARROGANCE! Garlic2010 said: (又係佢誤人子弟傑作) 王老闆收了100元假鈔,失去79元的找續和21元的貨物,所以王老闆的損失是100元。 ========================================================= The purpose of this criticism is to show Garlic2010’s conclusive statement is FALSE. IS THE $3 PROFIT EXISTED??? 為甚麼貨物價值是21元而不是18元呢﹖因為如果賣給真正的顧客,王老闆可以收到21元,所以21元是王老闆的真正損失,這個也是經濟學機會成本的觀念。By Garlic2010. His statement is false. The opportunity cost of a decision is based on what must be given up (the next best alternative) as a result of the decision. Any decision that involves a choice between two or more options has an opportunity cost, according to NetMBA.com. Did Mr. Wong make a decision on which customer to sell? Can Mr. Wong choose which customer to sell? Did Mr. Wong intentionally forgo the $3 profit to being deceived? THE ANSWER IS NO, SO THERE’S NOTHING RELATED TO OPPORTUNITY COST!!!!!!!!!
