※ 引述《zong2006 (小周鳥)》之銘言： : 來源: 100 年度交大交管研究所考題 : 科目:經濟學 : 問題:Dolores used to work as a high school teacher for $40000 per year : but quit in order to start her own catering business. To invest in her : factory, she withdraw $20000 from her saving, which paid 3 percent interest : and borrowed $30000 from her uncle, whom she pays 3 percent interest per year. : Last year she paid $25000 for ingredients and had revenue of $60000. She asked : Louis the accountant and Greg the economist to caculate her profit for her. : a. Louis says her costs are $25900 and Greg says her costs are $66500 : b. Louis says her costs are $25000 and Greg says her costs are $65000 : c. Louis says her profit is $66500 and Greg say her costs are $66500 : d. Louis says her profit is $75000 and Greg say her costs are $41500 個人算出來是A 稱不上是高手(中手都稱不上?) 有錯請指教 先從會計成本著手 因為 經濟成本=會計成本+機會成本=會計成本+正常利潤 而會計成本就是實際上有的成本 餐飲業會計成本是材料錢加上借來的錢=30000*0.03+25000=25900 而機會成本就是放棄這個決策所能賺得最高會計利潤 餐飲業的機會成本就是當老師 又利潤等於收入減成本 當老師收入是當老師薪水+原本的存款收入=40000+20000*0.03=40600 因為沒有提到當老師時的成本 假設成本為零 利潤即為收入減成本=40600-0=40600 所以 餐飲業經濟成本=會計成本+機會成本=25900+40600=66500 --
