Nintendo Wii by Rachel

Will Nintendo's Wii Strategy Score?
If the Japanese company attracts new gamers with its innovative but not quite cutting-edge console, it could alter the industry

(September 20, 2006 by Brian Bremner) 

Killer processing power, high-definition graphics, WiFi connectivity, massive storage capacity—when it comes to game consoles, the presumption has always been the more functionality and speed, the better. Well, Nintendo (NTDOY) will launch its next-gen game machine called the Wii in the U.S. on Nov. 19, followed by Japan and Europe in early December. And the Kyoto-based company is making a huge strategic bet that "less is more" in the global game-console market.

Compared with the Sony (SNE) PlayStation3 and the Xbox 360 by Microsoft (MSFT), the Wii doesn't boast blistering chip speeds or cutting-edge graphics. Still, it's a cool game console and boasts some unique features, such as a wireless controller that can send a signal up to 30 feet away. It will retail for about $250 in the U.S. and include one wireless controller, one "Nunchuk" controller, and five different sports games.

It will also cost less than half what Sony hopes to fetch for its PS3, due out in November in the U.S. and Japan (Europe will have to wait until March, 2007). The PS3 features a super-fast Cell processor, which was co-developed with IBM (IBM) and Toshiba (TOSBF), and a Blu-ray DVD player that promises to deliver high-definition video. The standard Xbox, already on the market for about $400, is powered by IBM chips that also pack plenty of processing oomph, scads of memory, and quality graphics.

ALTERNATIVE APPEAL. Nintendo is clearly trying to position the Wii as a low-budget alternative. Although it also features an IBM chip, Nintendo's development team concluded that "while we needed adequate processing power, there was a threshold beyond which customers didn't really need more," said Nintendo of America President Reggie Fils-Aime. By not investing heavily in a technology like Blu-ray, the "Wii will be profitable from day one," he adds (see BusinessWeek.com, 9/14/06, "Hot Chips and Cool Consoles").

Nintendo thinks its game consoles—the Wii and the Nintendo DS handheld—will appeal to a mass market of first-time game players, women, and older consumers not typically drawn to this form of interactive entertainment. The Wii "has been designed to appeal even to people who aren't interested in games," Nintendo President Satoru Iwata told reporters near Tokyo last week.

Investors like Nintendo's chances. The company's stock is up 74% since April, and its quarterly results released in July were robust thanks to the DS. For the three months through June, Nintendo's sales rocketed 85%, to $1.1 billion, while operating profit increased almost eightfold, to $248 million. A weak yen helped, but a tripling of DS sales to 4.54 million units was the biggest factor behind the better-than-expected results (see BusinessWeek.com, 7/25/06, "DS Pays Off for Nintendo").

ADVANTAGE SONY? Though the Wii doesn't boast all the features and processing firepower of its rivals, Nintendo believes its easy-to-use controller will give it an edge. The Wii's wireless controllers can be moved through the air like a virtual sword, tennis racket, or weapon to pinpoint targets in a game or rifle through the Wii channel menu. About 30 new game titles will be available by yearend, the company says. Nintendo expects to ship 4 million boxes, primarily to the U.S., this year, and another 2 million through March, 2007.

Few expect truly dedicated gamers to choose the Wii over the PS3 or Xbox. And ultimately, the advantage may go to Sony. Yuta Sakurai, an analyst at Nomura Securities in Tokyo, expects the PS3 to sell 71 million units by 2011, compared with 40 million units for the Wii. Microsoft, meanwhile, is planning a stripped-down version of the Xbox without a hard-disk drive and other accessories that will cost about $250 in Japan, where the U.S. software maker has endured disappointing results. There's also a danger that the Wii could cannibalize sales of the DS, which has been a smash hit with casual gamers thanks to its user-friendly design and titles such as New Super Mario Bros., Nintendogs, and the Brain Training for Adults series.

It's definitely going to be a World of Warcraft moment in the game-console market when the Wii, PS3, and Xbox are all competing for consumers' hearts and dollars, euros, or yen. A particularly strong showing by Nintendo may signal that reaching new gamers is more about ease of use than processor muscle and high-end graphics. If so, the Wii could be a game changer.

Evaluation
The article above was written before the official launch of the Nintendo Wii. About 3 years on, the Nintendo Wii is indeed, dominating the gaming market. Despite losing out on graphic imaging quality to nearest competitors (or substitutes in economics terms), it has managed to dominate the gaming market through its unique controllers and gameplay, which makes its demand inelastic as none of its competitors are able to replicate the Wii's gameplay. Unlike competitors such as Microsoft's Xbox 360 and Sony's PS3, the Nintendo Wii engages and allows users to have physical exercise with its one-of-a-kind controllers and games. The quantity demanded for the Nintendo Wii would then soar as many gamers would want to have the unique experience of gaming with the Wii. As such, they have created a monopoly in the gaming market because there are almost no similar controllers or gameplay similar to that of the Nintendo Wii. 

Making use of this fact, the company, Nintendo is able to set the price for the Wii console system and the rest of the gaming market (Sony, Microsoft) would have to follow suit and set the prices of their own gaming consoles lower than that of the Wii's so that the low prices would still attract people who are willing to buy the Xbox 360 or the PS3 in favour of the Wii.

This shows cross-elasticity of demand and inelastic demand for a product that is one-of-a-kind. 

Anomaly in demand analysis: exceptional case

Hi everyone, here is some food for thought; something closely related to what we have learnt, yet exceptional in its own right: an anomaly in demand analysis, encompassing a very unique case.

First of all, let's recap on some demand concepts. Demand is the relationship indicating the quantity of a well-defined good or service that consumers are willing and able to buy at each possible price during a given period of time, ceteris paribus. A demand curve, with the y-axis being price of good and x-axis being quantity of good, would be downward sloping with a negative gradient. For every unit increase in price, the quantity of the good demanded by consumers would decrease theoretically, and vice versa. As such, changes in prices of goods would result in a movement along the demand curve, signifying a change in the quantity of good demanded. The law of demand states that an inverse relationship exists between the price of a good and the quantity demanded of the good, ceteris paribus.

This is something that we are all very familar with. However, this is not always the case. The demand curve need not always have a negative gradient. There are times whereby the demand curve can be upward sloping with a positive gradient! Surprised? Be surprised no more.

A very prominent example illustrating this anomaly in demand analysis would be Griffin goods. What are Griffin goods? A Griffin good is a product whose demand increases as the price goes up. This can be seen as an unusual economic phenomenon, because it actually defies the law of demand. In the case of Griffin goods, a direct relationship exists between the price of the good and the quantity demanded of the good, ceteris paribus. Why is this so?

The reason behind this anomaly is actually very simple: perceptions on the Griffin good by its consumers. For some goods, its consumers may buy more if its price is higher. To them, the price of the good could be an indicator or a label of its quality or useability; the higher its price, the higher its perceived intrinsic value and thus the more of such consumers buy it. For example, a particular brand of beer may not sell very well if it is priced low because consumers may think its low price indicates its poor quality. However, if the price of such goods are higher, consumers may want to buy more of it because they may feel their high prices depicts them as being "valuable". Thus as price of the good rises, quantity demanded also rises in these cases because consumers feel that higher prices are a measure of increasing quality or useability. This is a simple yet major exception to the law of demand as well as the shape of the demand curve for Griffin goods. Because quantity demanded rises together with price, one can infer that Griffin goods, most of the time, are likely to be luxury goods.

This is just one exceptional case to Economics; I will post more next time =D

Swine Flu and Face masks

Under the current possible swine flu crisis, demand for pharmaceutical goods has shot up significantly. This surge in demand is especially so for face masks which help to keep out germs that spread via water droplets expelled when a person coughs or sneezes. According to Straits Times report, at the Watsons store at Serangoon Central, it sold 30 masks on 27 April 2009, as compared to only five on 26 April 2009. And almost 150 face masks were sold over the past three days at the Watsons store at Parkway Parade, from one or two a day.

As marked by the statistics, under the threat of a possible epidemic (Swine Flu), the demand curve for face masks has shifted to the right as denoted by the graph (from DD to DD1), as people are willing to take necessary precautions to reduce the probability of contracting the flu from sick individuals. As the threat of swine flu becomes more imminent, and the government steps in to promote the use of face masks, the demand curve is likely to continue shifting to the right (DD2). The suppliers, responding to the current trend of consumption, are likely to increase the supply of face masks. Moreover, due to the ease of production and short time taken in production, producers could easily adapt to this change in demand rapidly. In other words, the supply will increase as shown by the shift of the supply curve to the right (SS to SS1). The shift by both the demand and supply curves to the right will result in the increase in quantity of goods, with its price indeterminate.

Canteen food




Due to the availability of substitutes which is the high school canteen food, the demand for JC canteen food is price elastic (1 < lEpl < infinity). When demand is price elastic, as price changes, quantity demanded changes more than proportionately. This is because as the price of the JC canteen food increases, students will prefer high school canteen food as it is a close substitute. Thus, the quantity demanded has a greater effect on total revenue than the change in price. Take for example, an increase in price from $2 to $3 as shown in figure 1.

At the price of $2, there will be a demand of 15m units and the total revenue is $30m which is given by the area 0CEG. When price increase to $3 (50% increase), quantity demanded falls more than proportionately to 10m units which is 67% decrease. The total revenue decrease to $15m as shown by area 0ABF. Since area DEFG is greater than area ABCD, the total revenue has decreased.

As these 2 goods are closely substitutes, the cross elasticity is always positive which means a decrease in the price of one good will lead to a fall in the quantity demanded for the other. For instance, when the high school canteen vendors decrease the price of the food they sell, JC canteen vendors have to slash price to prevent students from turning to cheaper alternative. At the same time, it is wise for the JC canteen vendors to differentiate their products such as to improve on the quality of the food they are selling.

THE SWINE INFLUZENA!!! O:

OUTBREAK OF THE SWINE INFLUENZA

This IMPENDING CRISIS (or already is?) gripping our society.


- A new strain of flu: combination of bird, pig and human flu viruses.
- Epicenter of the influenza outbreak: Mexico City
- Spread through contact with infected PIGS

Tamiflu is a price inelastic. It has a very small number of substitutes, and in this influenza situation, its only closest substitute is Relenza, a similar drug which prevents infection with Swine flu viruses. Therefore, any change in price brings about a less than proportionate change in quantity demanded.
The Demand curve shifts to the right with a magnitude larger than that to the shifting of the Supply curve to the right. As the influenza situation worsens, with the publishing of more reports on the severity of the condition, rising death tolls and increasing worry among the public, governments will take immediate action to stock up its supply of Tamiflu. There is imminent fear than the 2009 swine flu outbreak will plunge the world into a serious pandemic as feared like the SARS incident back in 2003. In this short period of time, the demand for Tamiflu will rise significantly due to the change in consumers’ expectations.
To meet the high demand of Tamiflu, pharmaceutical industries will start to produce more of the good to cater to a higher number of needs. But due to patented laws on the drug, there are not many companies that are legalised to produce it. The supply of Tamiflu is price inelastic. When the demand for Tamiflu increases, price increases significantly while the output increases less than proportionately in response. (P2-P1 > Q2 –Q1)(sorry, the diagram is not clear enough!)

Consumer&Producer Surplus



Here is an interesting question on surplus:


Find the equilibrium price Po and the equilibrium demand Xo, and evaluate the consumer's surplus and producer's surplus.










Solution
Demand:p=-3x+21
Supply:p=9x^2/16, x>=0
Since at equilibrium, the curves intersect
=>-3x+21=9x^2/16
<->3x^2+16x-(16)(7)=0
<->(3x+28)(x-4)=0
As x>=0,
Hence equilibrium occurs when x=Xo=4,and the corresponding equilibrium price is p=(-3)(4)+(21)=9
Consumer surplus=Area A=(21-9)/2*(4)=24



















































Demand and Supply Curves Done by: Harrison

Recalled this when Mrs Toh said that the situation whereby many guys like a girl can be explained by the theory of demand and supply. Given that the girl is a good in the eyes of the guys, the price of getting her as a girlfriend would always be increasing as the quantity supplied is always stagnant, as the girl cannot split herself up to suit the demand of the other guys. This can be explained by Fig 1.0


As seen in the curve there is a rightward shift on the demand curve. This can be largely due to the non-price factor of consumer preference. Like how consumers demand for fashionable goods, the girl maybe the eye candy of all guys, thus causing an outward shift of the demand curve due to the increase in demand, causing the price of getting to know the girl to increase from P1 to P2.

DD/SS changes!

Metal Gear Solid 4 is a game that was released in mid-2008. It is a highly popular game because it is freaking cool XD! Anyway, there were a lot of magazine articles published about it, anticipating the release of this game and how everyone expected it to be a great hit due to the excellent sales for Metal Gear Solid, Metal Gear Solid 2 and Metal Gear Solid 3. They also provided a lot of screenshots of the game, raising expectations for the game and making everyone excited about this new game!
Hence, people thought that this game would really ROCK and that it would make an excellent game to add to their PS3 games collection, so they decided that they would buy it when it was released. So, with the help of publicity, demand for the game was raised.
Because suppliers foresaw the increase in demand for the game, they decided to produce more of the game! And so, both the demand and supply curve shift to the right, causing the equilibrium price and quantity to change। The quantity of the game produced increases, while price remains indeterminate. तदाह!

Marketable Permit (Carbon Credit) - by Tze Liang

Carbon Credit

Idea mooted as part of Kyoto Protocol

Aim: Meet the goal of reducing the world's greenhouse gas emissions by an average 5.2% relative to 1990 levels by 2012

1 Carbon Credit entitles to 1 Tonne of CO2 (Net Emission)

Costs for each carbon credit are around $10 to $40 (so low!)

In 2007, trade market for carbon credits is around $63 billion worldwide in 2007, nearly double that of 2006.

 Advantages

  1. Money from sale of carbon credit can be used to support carbon saving schemes. E.g. New Zealand has sold some carbon credits to fund some wind generation projects (clean energy).
  2. This scheme creates an incentive for companies/countries to research for green technology and tree planting projects. At the same time, it discourages companies/countries from polluting the atmosphere.
  3. Explain using the price mechanism (Demand and Supply).

Over time, more energy is required to support the growing population (e.g. China & India), and hence the demand for carbon credits would increase. The demand curve would shift right, while assuming supply is around the same, equilibrium price would increase.

This would then create a greater disincentive for companies to pollute.

 

Limitations

1.       Some companies are just buying carbon credit as a form of commodity, and selling it off for a quick profit when the price rises. (Abuse of system)

2.       The price of each carbon credit must set to be higher than what it takes to clean up

3.       It may be hard to evaluate the net emission of CO2 by each company / country

4.       Enforcement may not be effective in certain countries that are corrupted / inefficient.

5.       It is hard to determine the total number of permits to be sold / circulated in the whole market.

Cabbies in Singapore by Wai Chew (05)

I would like to analyze the market for taxies in Singapore using elasticity concepts.
Firstly, price elasticity of demand for taxies in general. Since taxi services are usually consumed by middle-upper income group, they tend to be price inelastic, where a change in price will bring about a less than proportionate change in quantity demanded. i.e. |Ep| < 1.

This is especially so during peak periods (e.g. 7 am to 9.30 am and 5 pm to 8pm on weekdays), rainy days, midnights, festive seasons and for some locations like Changi airport, Singapore Expo etc, where demand for taxi services is obviously price inelastic as people are desperate or really in need of the services to the extent that they do not really mind paying extra for the services.
This can be illustrated by the diagram (Figure 1)




From Figure 1, assuming price increase is for the peak hour’s period etc, it is observed that the demand is price inelastic for taxi services (indicated by the steep gradient of DD). Thus, it is wise for the taxi companies to raise their prices during these periods to increase their total revenue, as the change in quantity demanded has less effect on total revenue than the change in price.

For example, an increase in price from $2 to $5 as shown in Figure 1. At the price of $2, total revenue is $30m, given by area 0CEG. When price increased to $5 (150% increase), quantity demanded falls less than proportionately from 15m to 12m consumers (20% decrease). Total revenue thus increase to $60m shown by area 0ABF.

Secondly, cross-elasticity of demand for taxies. These are the main taxi holding companies, namely Comfort Delgo Corporation, which owns City Cab and Comfort, Premier Taxis for SilverCab, SMART for SMART Cabs and SMRT Taxis and also TransCab.

In this respect, each of the companies’ services are close substitutes, hence they have positive cross elasticity in relative to one another, which means that a decrease in the price of one good will lead to a fall in the quantity demanded for the other and vice versa.

Thus, usually, the firm will slash price when the competitors lowers price t prevent consumers from turning to cheaper alternatives, which is a “follow-suit” response. However, they could also become oligopolists, colluding to raise price as they are the only producers of taxi services.

For example, in 2006, ComfortDelGro raised fares for all the operators under its umbrella, and SMRT Taxis and TransCab followed suit. On 11 July 2008, ComfortDelGro announced the implementation of a $0.30 fuel surcharge starting from 17 July. Other taxi companies except Prime Taxis followed suit with different implementation dates.

I read this from one of my senior’s blog and I thought it was quite funny so I wanted to quote his post:

We sometimes just suck at things so our results may be less than proportionate to the efforts we put in. It takes a larger than proportionate increase in effort to cause an increase in results.



Assumptions:

1. At zero effort, we still get some results — not zero. This varies according to your intelligence.
2. As effort increases, results increases. This may not be true for some people, for results can fall even with additional effort put in.
3. Ceteris paribus condition is held true. For instance, the difficulty of the exam paper, the quality of the effort spent mugging.
4. Assuming short-run mugging spree condition.

So for different subjects, students have different effort elasticity of results. This is represented by the slop of the results curve.

Some people has a very high effort elasticity of results for economics — an increase in effort results (no pun intended) in a more than proportionate increase in results. Therefore they are said to have effort elastic results. But it is first prudent to examine the determinants of effort elasticity of results.

Determinants:

1. Intelligence Quotient (IQ). Smarter people generally have a more effort elastic results.

2. Academic foundation. Similar to IQ, but just how much you have mugged in the long-run also affect your effort elasticity of results.

3. Spare capacity of your brain. Similar to IQ. Some brains cannot respond quickly to a change in effort because they are already working at full capacity.

4. Time period of mugging. Some subject requires more time to prepare. Eg. Maths and Chemistry. Econs and bio just mug one day before the test and vomit everything out. Supposedly.

HAHA okay its pretty funny that’s all bye!

Demand & Supply Part 2

Demand for Bun (Jocelyn) vs Demand for Youtiao (Waifoon)
When White meets Black… then White meets White again

When the price of Waifoon increases, the demand for Jocelyn increases. This is because buns and youtiaos are substitutes and thus consumers like Huiqi will switch their preferences to cheaper alternatives for breakfast when price of one Dim Sum increases to satisfy similar consumer needs (YUM:D)

On the other hand, when the demand for Jocelyn increases, the demand for Ashleen (Soya bean milk) increases as well. This is because buns and soya bean milk are complements. People like to eat them together >)

Thus, using the theory of market equilibrium, overall demand for Jocelyn will increase but the overall price is still undetermined as this is dependent on the magnitude of change in the demand curve.

Moral of the story: Do you prefer buns or youtiaos?
