Part Two: Analytical questions. [注意字體工整、邏輯順暢與不要出現錯別字或注音(與火星文)！如果字跡難以辨認，視同未答。畫蛇添足、答非所問、不知所云、自曝其短，將不利得分。如昔，教師有權公告具有特色之作答。] 30 points
21. [20 points] Recall lecture 2. This is about the determination of efficiency wage that provides an incentive for a worker to work hard, not to shirk. A worker is paid at wage w > 0. If he works hard (as expected), his utility is w - 10. If he shirks, then with probability 1/4, he will be caught. Once being caught, he will be fired at once (and getting no pay). After being fired, with probability 0.05, he will remain unemployed and will be entitled to receiving unemployment benefit, which is 2. And with probability 0.95, he will be getting a new job at wage 6. If he shirks, then with probability 3/4, he will not be caught and his utility will be w.
(i) Use a decision tree to illustrate this worker’s decision-making.
(ii) Find the minimal wage providing an incentive for him to work hard. In other words, find the efficiency wage w.
22. [10 points] Suppose that you and I are playing the scissors-rock-paper game. We both show our choices simultaneously. The loser gives $1 to the winner. Nobody pays if there is a tie. Carefully draw a game tree to describe it.

To be fair, to be efficient, to be creative, to respond to good suggestions…
多謝 UB1 鄭如吟同學的建議。誠然，使用者付費，早已是文藻之美德。週二(March 25, 2008)上課時，我匆促估算的『每人應攤NTD80』，是依據暑修期間的全程開冷氣之小班經驗，脫口而出，衷心為計算錯誤道歉。更要感謝UB3同學勇敢指正，特地重新精算處理如下。
依據授課大綱，是否開冷氣、關閉門窗，由教師認定，無庸置疑。全班共58位同學，教師也應分攤。虛假的教師卡與謝師宴，爾後請免，自在不言中。
義工將專款專用，先購買1,000元的冷氣卡，1,000 除以59，約為17元，UB1以外的8人(含教師)，每人應繳25元，不囉嗦、不計較，確實也攤付上週的冷氣費。1,000 - (8)(25) = 1,000 - 200 = 800，則應由UB1班費，下週課程結束前，統籌支付。
爾後上課時，由義工插卡，下課取出，不得有誤。我們也正可精算，究竟冷氣效能如何。如果任何同學放任開啟門窗，浪費能源，將付出代價。1,000元的冷氣卡用完時，新卡片之費用分攤，也將是『UB1負責費用之51/59、其餘8人平均分攤費用之8/59』，期末之卡片剩餘金額，教師願意收購，義工平均攤還給全體付費者。
好事成雙，總體經濟學原理，比照辦理。其餘非建設性之不當言論，請留作個人夢話。

Cockroaches, chairpersons, teachers, and God – something about waiting
Ever wonder how in the world can these four words, cockroaches, chairpersons, teachers, and God, be put together? What follows is my naïve and random thought at your disposal.
When I was a little boy, life was kind of miserable. My father worked hard, was sent to various military bases as his duty required, and had very little time for his family gathering. Sometimes, my parents had a big fight after dinner, afterwards my mom would go out to have her hairs cut or washed at night. I was terrified, lying on bed, pretending that I was sleeping but wondering when she would come home safely, while the clock-ticking accompanied me thru the dawn. That was sad waiting, waiting my beloved one to come back to me.
On other quiet nights, I was also waiting. Not waiting for my mom but waiting for a big ugly cockroach to quietly leave the corner just one foot distance from my bed side. I could see it well, so did it. Guess that we both were staring at each other and waited for the other to retreat. Hey, where could I possibly go in the middle of the night at my own home? I prayed that it would go to the houses of some my nasty friends since they treated me badly at school. It had a lot of choice, did it? Why did it choose to be at my house as I had behaved as a good boy? [By the way, at that time the book “When Bad Things Happened to Good People” was not published.] That was another kind of waiting, waiting the bastard to get out of my sight. Of course, if my brother, presumed knowing its coming, intended not to kill the cockroach with a sandal, I probably won’t forgive him.
Many years later, as my social life was getting interesting, every now and then, I was also waiting, waiting for my loved ones to come back to me, both in heart and in a flesh. Some unexpectedly came and caught my breath, seized my heart, but eventually vanished. Endless love soon proved to be endless sorrow, followed by numerous sleepless nights. Some years ago, my heart was torn into pieces. Luckily, a person who was and still is deeply caring for me whispered: “Just want you to know that I love you and God loves you too.” Then I realized that I was waiting for the wrong person. The person I waited would never come back to me while she and God had been there watching for me all the time even I was not aware of. So, I learned that sometimes waiting could be stupid and have negative returns.
We all need to work to pay the bills. In my teaching career since 1988, I often had bad luck in having decent bosses. Some tampered the teaching evaluations, some altered the minutes, and some made false accusations. You might say that many of them got away because that God was taking a nap or their time was not up yet. But I chose to remind myself of what the book “When Bad Things Happened to Good People” was for. And I shall have faith and patience in God. This is another kind of waiting, waiting in style and with gratitude.
So much for having bad luck with chairpersons. One day, I thought in an American way: If you cannot beat them, why not join them? So, I became a chairperson myself. Very soon, life was never made busier. When the so-coined honeymoon was over, frustration and disappointment gradually ate up my soul. Then came another type of waiting, waiting for my 3-year appointment to expire. I bet that when I work on my memoir, I shall be proud of myself in stepping down the post in dignity and in perfect timing. As to applause or encore, a shy person like me would never expect nor appreciate it.
We teachers must deal with students in our entire career. So, I wait, wait for students to become far-sighted, to understand what the term grade inflation means, to value their education opportunities, to critically read my teaching materials as much as journal referees did with my manuscripts, and to be able to speak up and demand what their parents paid for. Overall and honestly speaking, I have been disappointed. But, an old saying rings the bell: “If you cannot stand the heat, stay away from the kitchen.” It all comes with the paycheck. So, again, I wait graciously till my retirement.
Students are kept waiting too. Sometimes they wait for teachers to show up; sometimes they wait for substitute teachers for courses that might be cursed. There was an old joke. Two professors were bragging about who was a better teacher. One professor said: “You know? If I am late for class for 20 minutes or more, my students were still waiting for me in the classroom. Am I a good professor or what?” Another replied: “Well, that probably was because that you were consistently late for class. In my case, should I be late for 5 minutes, all students will think that I must be prevented from teaching for reasons that were beyond my control, so they won't wait for me.”
Is God waiting too? Or, should we say, are God’s servants waiting? Many pessimistic people think that the world is in chaos. Bad things did happen to good people. On the one hand, messengers who delivered bad news were killed just for delivering the unwanted yet true information. On the other hand, falsified messages were spread at light speed to confuse those who do not have good faith. That reminds me of the Taiping Rebellion (1850–64). It is the wake-up time!
Finally, I am waiting, waiting for my intended audience, yes, I mean you, the Mighty Bosco and my dear Sister, to read this fable (or metaphor?) before we all report to Heaven's Gate.
Hallelujah!
Note: 如果『很會出奇招的教育部』要求，大專教師要參加英文寫作測驗，作文題目碰巧是「Waiting」，不知這樣寫，閱卷教授會不會欣賞啊？
Followup: At the time I wrote it (in early 2008), Jerry, my young and restless friend, told me that my intended audience simply won't read it. Well, I do believe that we are in the good hands of God. Evidence abound. Some asked for the hidden information about the cockroach. Here is the hint for smart people: from 07 to 06 to 03 (and to ?).
