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 我的想法: 怎麼算都沒有選項 我的算法是 Greg 是 經濟學家 用經濟成本概念則成本： 40000(停薪) 20000(開創事業花掉) 20000*0.03 (=600)(開創事業花掉的錢損失的利息) 30000*0.03 (=900) (借錢要還 所以借錢成本只算利息部份) + 25000 (ingredients材料費) -------------------------------- = 86500 沒這個選項 另外就算扣掉材料費 = 61500 也沒這個選項 這還只是經濟成本 經濟利潤 = 60000 - 61500 = -1500 賠一千五 我想我整個觀念都錯了 有請高人指點 另外題目也要算會計利潤 但經濟利潤我就算不對了 更別說會計了~~ --
