学术英语课文翻译Unit1人们如何做出决策理性的人认为在保证金1.经济学家通常假设人是理性的。
理性的人们系统地,有目的地做最好的,他们可以实现他们的目标,考虑到可用的机会。
当你学习经济学,你会遇到公司决定雇佣多少工人,有多少他们的产品生产和销售利润最大化。
你也会遇到那些决定花多少时间工作和买什么商品和服务产生的收入来实现最高水平的满意度。
2.理性的人知道生活中的决策很少是黑白的，但通常是灰色的。
在吃饭的时候，你面对的不是空腹或是像猪一样进食，而是吃额外的一匙土豆泥。
当考试开始时，你的决定不是介于两者之间，而是让他们减少或学习一天24小时，而不是花更多的时间复习笔记而不是看电视。
经济学家用“边际变化”这个术语来描述对现有的行动计划的调整。
请记住，边际意味着“边缘如此边缘的变化是在你正在做的边缘周围的调整”。
理性的人往往通过比较边际收益和边际成本来做出决定。
3.例如，考虑一家航空公司决定向待机乘客收取多少费用。
假设撒德躺在横跨美国的200座飞机上，航空公司损失100,000英镑。
在这种情况下，每个座位的平均成本是1,000美元/ 200美元，这是500美元。
有人可能会得出这样的结论：航空公司不应该售出票价低于500美元的机票。
事实上，一家理性的航空公司通常可以通过考虑利润率来提高利润。
想象一下，一架飞机即将起飞，有10个空座位，候机旅客在门口等候，将支付300美元的座位。
航空公司应该把票卖掉吗？当然应该。
如果飞机有空座位，增加一个乘客的成本很小。
乘飞机的平均成本是S500，边际成本仅仅是额外的乘客将消耗的花生袋和苏打水的成本。
只要备用乘客支付超过边际成本，售票是有利可图的。
4.边际决策有助于解释一些令人费解的经济现象。
这里有一个经典的问题：为什么水这么便宜，而钻石这么贵？人类需要水来生存，而钻石是不必要的；但出于某种原因，人们愿意付出更多的钻石比一杯水。
原因是一个人愿意支付任何好处是基于一个额外单位的好处会产生边际效益。
