Funny Problem Set

Short, Medium and Long Run
Consider the “gold-farming” industry (see Problem Set 1) which we can safely assume to be perfectly
competitive. Online game players can buy virtual gold coins from “farms” that kill monsters for a living.
Aggregate demand for virtual gold coins is governed by the function
p p D 100 400 ) ( − =
where p is the price of virtual gold and D(p) is the daily amount of coins demanded at that price (in
hundreds).
There are many potential gold farmers. Setting up shop requires buying a warehouse, stocking it up with
computers, and hiring the workers/players to operate the machines. We will represent the production
technology with the function
3 / 1 6 / 1 l k g =
where g is the quantity of gold coins obtained in a day (in hundreds), k is the amount of capital
investment, and l the amount of labor hired.1 Each firm also incurs a fixed cost of 1/6 dollars per day to
pay for electricity and internet connections. The rental rate of capital is ½ dollars per day, and the wage
rate for labor is $1. Workers in these firms are hired on a daily basis, and therefore the amount of labor
can be varied daily. The amount of capital used by any firm in production cannot be varied on a daily
basis, but can be adjusted on what we call here the “intermediate run” – a month. In the long run (five
months time), in addition to adjusting the amount of capital used in production, firms can enter or exit
the industry.
a. What is the long-run equilibrium in this perfectly competitive industry? Find the long-run
equilibrium price, total quantity, and number of firms active in the industry.
Suppose that the industry is at its long-run equilibrium and there is an unexpected increase in the
demand for virtual gold coins. The new demand function is:
p p D 150 750 ) ( − =
Find out the industry’s response in
b. The short run.
c. The intermediate run.
d. The long run.
In each case, find the equilibrium price, total quantity, and number of firms active in the industry.


1 Generating an account with a “level-60 Shaman” (see article in Problem Set 1) requires the input of highly trained and
specialized labor. In this problem we consider the simpler task of earning virtual gold coins which does not require
highly trained players – hence, the necessary workers can be found in relatively abundant supply.

Found this photo on DHS' website.
Quite Cheesy. Can you imagine Mr. Kiw doing this in real life?
But I have to admit, he's the most identifiable person in DHS....

this article made me think about you overseas ppl.

ST Forum Jan 10, 2006
'EXAM MERITOCRACY' VERSUS 'TALENT MERITOCRACY'
Why top S'pore students aren't world beaters

I REFER to the article, 'There is no textbook formula' (ST, Jan 6), by Fareed Zakaria in which comparison was made between the education systems of the United States and Singapore and how although Singapore students top global science and maths rankings regularly, they do not become world beaters 10 or 20 years later.

Very few of them actually become 'truly top-ranked scientists, entrepreneurs, inventors, business executives or academics'.

Singapore's Minister of Education, Mr Tharman Shanmugaratnam, admits that 'ours is an exam meritocracy' as opposed to America's 'talent meritocracy' and that America's 'culture of learning that challenges conventional wisdom, even if it means challenging authority', is not prevalent in our system.

A fact widely known in the scholar community is that Singapore's top junior colleges have had, for the past years, among the highest percentage of successful applicants to America's Ivy League universities (from any high school worldwide) and most graduate among the top of their cohorts in these elite colleges.

The questions that need to be asked - and answered - would be, So what happened? How do we make these top-ranked students go on to be top-ranked adults in their chosen vocations?

Does the fact that scholarship-awarding bodies like the Agency for Science, Technology and Research's insistence on a Grade Point Average of 3.8 (equivalent to first-class honours) before students will be considered for overseas PhD studies not send the signal that the '3.8' is all that matters, to the exclusion of all else?

Our students then take the cue from there and I would be most surprised if the scholarship holders chose challenging courses - and professors - en route to their '3.8'. My gut feeling tells me that most would choose safe courses, perhaps even living in virtual Singapore 'scholar' communities in preparation for tests/exams.

Most would, of course, prove our minister correct that they are 'exam-smart' and have their magical figure of '3.8'.

I would have thought that as these are already students of 'proven' record, that it would be beneficial to allow them to explore the width and depth of their human capacity by setting less onerous standards.

They will then better benefit from their overseas education and may even learn to take 'risks'. For example, the bio-medical scholarship holder may then sign up for Anthropology or the budding engineer, Political Science, etc.

Our scholar students will then 'have a life', like the rest of the undergraduates.

Most of these students are government-sponsored, with planned and ingrained 'fast-track' career paths. The tendency might be for them to think that they have got a 'great thing' going for them and that it would be most stupid and counter-intuitive to 'rock the boat' by initiating change. But change there must be if we are looking for 'world-beaters'!

The organisations in which these scholars work have their work cut up for them as they try to prevent the obviously talented 'returned scholar' from becoming just another mediocre corporate 'climber'.

太多

曲:陳綺貞 詞:陳綺貞 編:陳建騏

喜歡一個人孤獨的時刻 但不能喜歡太多
在地鐵站或美術館 孤獨像睡眠一樣餵養我
以永無止盡的墜落 需要音樂取暖
喜歡一個人孤獨的時刻 但不能喜歡太多

喜歡一個喝著紅酒的女孩 在下雨音樂奏起的時候
把她送上鐵塔給全世界的人寫明信片
像一隻鳥在最高的地方 歌聲嘹亮
喜歡一個喝著紅酒的女孩 但不能喜歡太多

喜歡一個陽光照射的角落 但不能喜歡太多
是幼稚園的小朋友 笑聲像睡眠一樣打擾我
我們輕輕的揮一揮手 凝結照片的傷口
我喜歡一個陽光照射的角落 但不能喜歡太多

喜歡一個人孤獨的時刻 但不能喜歡 太多
