<p>很弱得几个关于机会成本的问题：（顺便问下 如果我现在薪金是10W，但是还有一份30W的工作要我去，那这时候我的收益是10W，大于30W，这个时候存在机会成本吗，具百度百科说好像不存在·····）</p><p>1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; You are planning a trip to Montreal, which is 500 miles. Except for the cost, you are completely indifferent between driving and taking the bus. The bus ticket costs $200. You do not know how much it would cost to drive your car, so you call Hertz for an estimate. The person you speak with tells you that for your make of car, the costs of a typical 10,000 mile driving year are as follows: </p><p>Insurance &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $1000 </p><p>Financing (Interest) &nbsp; &nbsp;&nbsp;2000 </p><p>Fuel &amp; Oil &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;1000 </p><p>Maintenance &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;1000 </p><p>Total &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $5000 </p><p>A non-economist calculates that these costs sum to $0.50/mile and uses this figure to compute that the 500 mile trip will cost $250 by car.&nbsp; The non-economist concludes that you should take the bus, because it is cheaper. </p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a)&nbsp; Is the calculation performed by the non-economist correct?&nbsp; Should you</p><p>decide to take the bus or drive your car? </p><p></p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Suppose that, when you drive, you tend to get one traffic ticket ($80) for each 200 miles that you drive. In this event, is it cheaper to drive or take the bus? </p><p></p><p></p><p>2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Big Sugar will give a free concert at Simon Fraser University the same night that Great Big Sea will perform at the University of British Columbia. </p><p></p><p>UBC charges a $3 fee at the door.&nbsp; You live in residence at Simon Fraser University and choose Big Sugar’s concert, but your next best choice for the evening is to hear Great Big Sea. The opportunity cost of hearing Big Sugar is: </p><p>a.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The dollar value to you of hearing Great Big Sea minus the time and money cost of driving to UBC and paying the door fee. </p><p>b.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The time and money cost of driving to UBC and paying the door fee. </p><p>c.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The dollar value to you of hearing Great Big Sea plus the time and money cost of driving to UBC and paying the door fee. </p><p>d.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The dollar value of the income that you could earn if you worked at your part-time job instead of attending Big Sugar’s concert. </p><p>e.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; None of the above. </p><p></p><p></p><p>3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; An athlete gives up a job that pays $30,000 per year to train full-time for the Olympics. She receives a grant of $8,000 per year from Sport Canada, but her training expenses are $12,000 per year. </p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; What is the annual opportunity cost, expressed in dollars, of this individual’s decision to train for the Olympics? </p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If Sport Canada were to eliminate its grants to athletes, how would this affect: </p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;</p><p>(i) the opportunity cost of this athlete to train for the Olympics? </p><p>(ii)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the number of Canadians who would choose to train for the Olympics? </p><p></p><p>(c)&nbsp;&nbsp; If food and shelter for this individual cost $8,000 per year, how would this affect the annual opportunity cost of her training for the Olympics?</p>
