Efficiencies of Facebook

Social-networking sites have taken the internet by storm in recent years; the likes of Facebook, Twitter, MySpace etc. have become integrated into the lives of many, many people across the globe. The desire to 'connect' with friends, and sharing your every detail with people who may or may not have interest in your lives have become a social norm among people, particularly between the ages of 17-24. Facebook is still topping the charts for number of users in 2013, ever since its introduction back in 2004, with Blogger and Twitter marginally close behind. Facebook, with its iconic thumbs up sign, is a commercial success in its own right, with around 1.11 billion active users globally. Expect this number to keep on increasing.

*"Like this, Like that": Facebook's iconic Thumbs up sign

Its uses are extremely varied and versatile due to the nature of the site being the 'middle-ground'/platform for many other technologies. One of the most common examples is Instagram, an online photo-sharing and social-networking service that allows users to take photos, apply filters to them, and post on their profiles with whatever hashtags the user deems 'suitable' for the photo. (E.g. #Yolo, #swag). It has become so popular that Facebook announced its integration into the sites' system. Hashtags have been around for quite some time in other social networking sites, particularly Twitter who fueled the trend. To start off, why did Facebook decide to do this? If you thought it was to do with money from advertisements, then you're correct.

In many cases, the one sharing the instagram photo will always put many hashtags, hardly ever putting only one. What incentive is there to spend time typing many hashtags? Is there a common relationship between the number of hashtags and the person's social behaviour? Humans are rational; they respond to costs and benefits, and appropriately change their behaviour and actions. Thinking it this way, the benefits of putting hashtags outweigh the costs of putting hashtags, or simply put, the pleasure of making up funny hashtags is worth the persons' time spent doing it.

There are many questions regarding the usage of Facebook. Two example questions include: "On average, how often would you post something on Facebook?". "How many people do you have as friends are actually friends?". In this post, I will be exploring the common functions used and common behaviours shown by Facebook users, and their relations to efficiency.

The first type of efficiency (or more accurately, productivity in this case), is the most obvious and simple: time spent. The time spent on Facebook varies very differently between individuals. Many people will think that those who spend more time on Facebook is much less efficient in browsing through his/her news feed, other people's photo etc., and conversely the ones that spend less time are more efficient. That's not necessarily true is most respects unless all the internal factors that would affect browsing time are identical averaged across a number of times used (examples include: number of posts on news feed received, number of posts made by the user, number of photos viewed etc.). In the ideal case above, a direct comparison is possible and easy to compare browsing efficiency between the two users, however, it is difficult in real life for such a perfect scenario to occur. Overall though, the important thing to know is that the frequency of activity on Facebook per time spent will differentiate the productivity between different users.

The next type of efficiency is information filtering. Information is important for efficiency in any market regarding the consumers because it allows for a more allocatively efficient market system, or how the majority interprets, a more useful and convenient browsing experience. Though, not all information you receive on your news feed or notifications are particularly interesting or suitable. Imagine how dull the user experience is when you scroll down your news feed and nothing interests you, and even if you eventually find one thing interesting, you may have had spent surplus time looking through a hundred statuses, adverts etc. Facebook arranges the news feed chronologically sorted into two arranged sets: "top stories" or "most recent", neither of which are particularly effective in filtering useful information actually. So is there a way to improve this function?

Well actually there already is. Users have the option to select 'close friends' or 'family' among their friends, and then click on the 'Friends' sidebar to rearrange the news feed according to the user's choice. Another option is to make a default news feed that arranges your news feed so that the people you have the most frequent activity with (sorted by number of page views, chat messages, photos tagged, pokes, birthday messages etc., or through the manual selection of friends the user wishes to place priority on the news feed) will have priority in the news feed arrangement. It should be relatively simple to do, so the Facebook development team would not be too troubled while improving prioritized information flow for users.

Other than for leisure/entertainment, Facebook offers a platform for firms and individuals to create pages that showcase themselves, their qualities, or promote what each of them has to offer to the public. Additionally, it is essential that the page provides a worthwhile service to those who use it, and most importantly, be worthwhile to the firm or individual for providing the service. For example, my Economics blog offers a service to people who are interested in Economics, IB students taking Economics or doing an Economics Extended Essay, or people and friends generally interested what I write (praise or criticism). All the above points are viable justifications for my page having a beneficial effect on Facebook users of those market segments, so I can assume it is efficient for the viewers (consumers). However, what benefits do I, the producer, get from writing articles and posting it on Facebook? Psychologically, it feels very rewarding when others commend me for the effort I put in. Objectively, continually analyzing and writing allows me to broaden my horizons to develop my thinking abilites. Other potential benefits include differentiating myself as a applicant from other competitors when I apply to universities or jobs, and making money through blogging (not yet). Overall, I think it's safe to say that my blog is efficient for both my target Facebook users and myself.

The third efficiency is inspired by the legendary "Undercover Economist", Tim Harford. In chapter 2 of his awesome book, he defined an efficient situation as "a situation in which it is impossible to find a change that would benefit an individual(s) without making someone else worse off." We can isolate each of the categories as a potential service to the Facebook user who looks at them. Each of these services can be beneficial, neutral, or harmful to the Facebook user. For example, reminding or telling someone of an important event he must attend is a merit service that benefits that person without causing any negative effect to others, therefore the service it offers will make the Facebook user experience more efficient. However, offending someone via messaging, or posting a particularly embarrassing photo of that person will upset them, thus it can be argued that it is not efficient to that person. You will notice that for both scenarios, the respective positive and negative effects mainly affect the individual subjected to the primary effects of receiving the information. If we look at the embarrassing photo example from an indirect/outsider point-of-view, although the person on the photo is the subject of cyber-bullying, others may find it very amusing and reward the photo with a 'like' in the form of a payment. If efficiency in this case represents the information received, there will be a mixture of positive and negative things, thus dulling the overall efficiency to the user. The most common form is analyzing the content to look for positive or negative effects to the user. Of course, the effect will vary from one user to the other. This type is more complicated to analyze as the time lag in between posting, liking or sharing will have any secondary effects in the future.

After combining the above points, it seems that the entire concept of Facebook is a market system in itself. Posts, Statuses, Shares, Photos are goods/services from producers (or providers) that become accessible to consumers via news feed, then receive a payment by people liking or commenting. Overtime, this one-dimensional market process evolved into a two-stage transaction process. A perfect example for this is: "Like for a tbh ("to be honest", but everybody knows that)". For those that have never came across this, here's how it works. First, the person types "like for a tbh", then waits for the likes to come in, and finally spends quite a lot of time (or little time depending on the number of likes) writing tbh's for everyone. And as an added bonus, if the tbh is good, it may be rewarded with a few likes as gratitude. In essence, the transaction goes from the producer to the consumer twice: firstly offering the service, then acting upon the consumers who accepted the service. However, like with any market system, there exists imperfections. Here are some examples:


  1. Some people who you have as friends on Facebook may be a complete stranger to you, so whatever they post may not be relevant to you at all. 
  2. Chats are private and conceal information to a third party. (Not exactly a bad thing, we like our own privacy)
  3. Occasionally when you complete any Facebook activity, you may feel that you did not receive the optimal payment for the quality and/or quantity of your post or whatever. 
  4. Asymmetric information between the friends of an account may occur as a result of different levels of access and transparency to information like photos. Remember, not all friends are treated the same!
  5. False information: not everything about that particular person profile details are accurate like date of birth, education, and workplace.
  6. Inaccurate payments: for any type of FB activity, the producer may receive insufficient or excessive payment for what it's worth.


The most efficient scenario only occurs when Facebook is perfectly efficient in terms of the content observed, the minimal time one spends relative to the amount of relevant content to that individual, and the perfect allocation of payment. The allocative efficiency is determined by factors such as the content. Realistically, it seems impossible for social-networking sites like to achieve perfect efficiency; that is the unfortunate truth. One rather unfeasible solution is to set a quota of content the user is allowed to post on his/her page daily. Limiting the content would potentially reduce the amount of irrelevant information observed, and thus makes one's visit more worthwhile. But posting statuses, photos, web-links is what makes Facebook what it is. With much fewer posts by your friends, or conversely posts by you to share with your friends, your news feed would look bare and unappealing. If that happened, Facebook would not have become so successful. Another solution may be not to use Facebook at all; this would minimize the time wasted in front of your computer, gives people an incentive to become more active instead of remaining desk-chair potatoes, and cut off cyber-malice directed through harmful posts. But losing a significant means of communication greatly reduces access to information, whether good or bad, thereby widening the asymmetric information gap. Also, if one person quits, that is hardly going to generate a domino effect where it makes everyone quit, so in the end, it is a pointless exercise.

Hope everyone enjoyed this long post and forgive my long absence (summer hoilday chill time!). It is the start of the new school year for many students, good luck!

Site Changes: Introducing TN Economics

Hello everyone!
Noticed the new site background? I hope it looks better than the original one. Anyway, I have been thinking hard for a while, and I decided that the name 'IB Economics Blog' was too...dull, and boring. Furthermore, since I do quite a bit of personal writing other than IB material, I renamed it after my initials.

The site url has also changed to: bigtuniteconomics.blogspot.hk

I will be attending LSE next year studying economics. Hopefully I could improve my own economic analyses over the time spent at university. Thank you for your consideration.

Niseko Snowboarding Holiday

Half a year ago, I and many other students endured another stressful term in the IB curriculum. The first term of Year 13 is unanimously the most stressful; in my case, I had 6 major coursework and examination deadlines all in the minute space of 3 weeks. So it was time for a breather, and since it was the winter season after that stressful period, what better activity to do than snowboarding down the slopes of the Niseko ski resort mountain in Hokkaido, Japan? It was my ideal holiday, no doubt.

Why is Japan so fantastic? Quite simply, they are the whole package. Personally, I love their range of delicacies (sushi, ramen, yakitori, tempura tendon, yummy snacks etc.), well-mannered and friendly people, services, technology, culture, and their remarkable attitude to be on time. However, from an economists' point-of-view, the most impressive thing about Japan is that their economy is very robust. All three of their sectors, Primary (raw materials/commodities), Secondary (manufactured goods), and Tertiary (service-related industry) sectors are  mature, meaning low-risk investment and high percentage of profitable returns once the recession has subsided, and producers attempt to resuscitate the economy by generating greater export revenue. In the past, Japan has been very protective of its specialty products. Today, this trading behavior is still seen but to a lesser extent. What's the reason? Simply to increase exports wherever they can, even if it meant making it accessible to consumers outside of Japan and decreasing the novelty of their products.

*"Access to the ultimate luxury" - Last year, 1,500 Kilograms of rarely exported Japanese Kobe beef were exported to Hong Kong supermarkets. All the Kobe beef were sold out in a matter of hours.

Japan has always been conservative when it comes to local traditions and products. In the current economic climate, one could say that it was the correct strategy, as Executive chef of the HK Intercontinental hotel, Erik Idos deemed that Japan were "wise" to open and expand their beef export market. But more importantly, why did they excise this 'closed-off' trading behavior in the first place? Two reasons come to mind. Firstly, it creates a sense of exclusivity of its resources. Japan understands the importance of protecting, and controlling its resources, thus maintaining its availability to locals. Although exports can increase revenues and access to worldwide markets, the producers produce at a limited volume and only sell them locally. Why? Because products that go overseas do not necessarily reflect the potential profit gain from exporting. For example, goods such as foods/snacks, which have a relatively short shelf life, that go overseas may spoil and result in waste. The same could be said for electronics. With the product life cycle becoming ever-so short, and rapid improvements in technology, goods that were unable to make if off the shelf may never be able to, therefore another source of waste is created. Secondly, and this is quite ingenious, is that all sectors in the Japanese economy could potentially make more money! If the producers decide to export, then the foreign consumers would only spend the amount the good costs, plus an additional cost to the Japanese producers by import tariff. In order for foreigners to access these products, they would have to travel to Japan. Let us map out the journey, during the peak winter season. An average family of four travels by air to Japan, after a merciless price discrimination by the airline companies (peak season flight tickets are more expensive than non-peak season tickets). In Japan, they immerse themselves in the snowy mountains for a week of endless fun and delicious local cuisine. On their last day, they go shopping around in the heart of the city centre for unique goods that are only available in Japan. And finally, they reached the end of their holiday, and hop onto the return flight back home. In comparison, the consumers spend much more money; producers from different industries (e.g. aviation, ski resorts, hotel, food etc.) all acquire a share of the consumption revenue, and the Japanese government receives greater tax revenue. In essence, Japan's reluctance to export certain local specialties eliminates the first option, and because there is only one choice, there is no opportunity cost. Anyway, it seems that this is no longer the case due to the convenient services of internet purchasing.

Since the financial crisis way back in 2007, Hong Kong tourists have had to dig deeper into their pockets to purchase Japanese goods and services because the exchange rate ratio between the two countries were slowly but steadily growing in Japan's favour. It was not actually Japan's economy that was going strong that led to the expanding difference in the exchange rates, but was US's the monetary policy of printing and increasing supply of US$ into the currency exchange market which contributed most. Since the HK$ is pegged to the US$, we couldn't do much about it, and just watch as the yen appreciates relative to the dollar. This was definitely not favourable to Japan as this meant losing competitiveness against other countries, especially in the technology market when large companies like Sony and Panasonic fall behind South Korean technology giants LG and Samsung. With exports and services making up 15% of the economy, it would land a very hard blow to its economy. Furthermore, not only do Japanese exports become more expensive, imports become cheaper too, hence further deteriorates the current account balance sheet.


As a result of the US's manipulation of the exchange rate market, the highest currency ratio of Japan compared to the Hong Kong dollar was around 0.1018 (HKD) : 1 ¥; which means that it requires a little more than $10 to acquire ¥100; that is quite ridiculous considering the high price of Japanese goods.

Moreover, during this period of time, and ever since the 1980's, Japan is actually suffering from deflation! Their first major deflation came from the liquidity trap as a result of over-investment and Japans' failure to cut interest rates quickly enough in the 1980's. Despite Japan's efforts to stimulate the economy by the "public works" project, their economy just would not seem to get going. Through this debacle, Japan has opted for "Quantitative easing" (QE'x', where 'x' is the quarterly period of the economic year), a policy based on the famous Princeton economics professor, Paul Krugman's idea to raise inflation expectations by cutting long-term interest rates, which should theoretically promote spending and investment. Quantitative easing did provide some help by easing the rate of deflation so that prices did not experience a complete sky-fall, but overall it was a menial act considering its ineffectiveness to create inflation. Japan still remains optimistic about the prospects of inflation, as the officials decided to double the economy's inflation rate target to 2%.

With the growing technological prowess from South Korea, and continually strong exports from China, Japan could not afford to lay back and watch their economy crumble under the competition. Fortunately enough, in the last month, Sony announced that it made its first net profit of ¥43 billion in over 5 years in the 2012 financial year. Although the profit figure is very small compared to the company's loss of ¥457 billion from the previous year, it bodes well for the long-term health of the Japanese economy. Lowering interest rates increases the supply of money into the currency exchange market, thus should have the effect of decreasing the value of the yen. As seen this year, it reached its lowest value in recent years of 0.075 (HKD) : 1 ¥. However, with the US irked by Japan's currency value manipulation, and new technology exports like the PS4, economists forecast that the value of the Yen would increase substantially. So for those that are visiting Japan on holiday this summer for the big summer sale (July 1st-27th), this could be the perfect opportunity to buy some before it becomes too expensive. Though that being said, Japan should be quite resilient to US complaints, and US growth is currently outpacing Japan's growth. Overall, to a certain degree, Japan has control over its currency valuation. It is forecasted that with US economy continuing to grow, the yen will drop in value relative to the US, and Hong Kong. This was illustrated by the decrease in value from 0.083 (HKD) : 1 ¥ to 0.079 (HKD) : 1 ¥ (as of 22/06/13).

Japan's new prime minister Mr Abe's 'Abenomics' pro-inflation policies are starting to show some effect. Instead of just continually lowering interests rates close to zero, the Japanese Central bank is aiming to increase the circulation of money within the economy, hoping to interest investment opportunities, and increase consumption. As with any policy, its effect would not be instantaneous, but it will be interesting to see if there will be any observable effect to the Japanese economy in the coming years. For now, whether the Japanese economy improves depends on local investments from domestic producers. If they do not act, "there is likely to be no positive contribution to gross domestic product", says UBS global economist, Paul Donavan.

Anyhow, back to my Niseko snowboarding trip. To my mind, Niseko is a wonderful place to explore the difference in the economics between winter and summer. Basically, Niseko can be divided into two conditions. Firstly, on the winter end of the spectrum, Niseko is a truly magical destination for any winter sport lovers. But why? How different is the snow compared to other ski resort areas? Looking more closely, snow is a natural occurrence that arise from a drop in temperature that converts what is originally rainfall into frozen water. If we treat snow as a natural resource, then there is no difference in the actual snow anywhere else in the world. So what makes Niseko different from other Japanese ski resorts that certain individuals crave so much for? The quantity of snow plays a large factor. On average, the Niseko ski resort area receives an average of 14m of snowfall, with a 10% standard deviation; statistical comparison also shows that Niseko averages the highest snowfall throughout the winter season. Additionally, in the 2011/12 ski season, out of 147 days of snowfall, only did it not snow in 27 days (percentage total of 94.5%). A frequently snowy resort keeps the place busy with tourists, thanks to the special powder snow experience and spacious mountain. They indeed market this mountain feature very well through variety of means such as on their website, posters, television advertisements.

*"Snowy heaven": Skiers immerse themselves into the powdery goodness Niseko has to offer.

Another quite interesting economic feature in the Niseko village is the competition between convenient store giants: Seicomart and Lawson. Below are some initial observations of the two stores:
  • Seicomart and Lawson are similar in size
  • Seicomart and Lawson typically sell the same goods. Key difference is that Seicomart has more raw ingredients (eggs, ham, vegetables etc.), while Lawson sells hot, ready-made foods (e.g. deep-fried chicken, yakitori etc.)
  • Both stores have a carpark facility in front of the store
  • Relative price of Seicomart goods are slightly more expensive than Lawson
  • Seicomart has 5 times the number of customers
At first, it seems strange that Seicomart have that many more customers than Lawson; in fact, I'd prefer the attractive lower priced goods in Lawson. Most features apart from some deviations in price, and the selling of raw and/or cooked foods, are identical. So what makes Seicomart have such a great advantage over Lawson? It does not seem that brand name or personal preference affect the market conditions between the duopoly. Answer? Location. Stores that sell either commodities or similar goods, who position themselves strategically to draw in demanding customers will have an overwhelming advantage.


From above, we can see that although both Seicomart and Lawson are located on the main road, Seicomart is within the perimeter of concentrated tourist areas while Lawson is on the outskirts of the Hirafu villlage. Tourists want convenience, and the short distance from their residence to Seicomart provides that convenience. Walking/Jogging/Running/Crawling to Lawson is not exactly what tourists want to do, especially during winter, and after a muscle-aching, full day of skiing/snowboarding.

Furthermore, Seicomart's insistence on selling raw ingredients is very perceptive. In the not so distant past, in an attempt to develop the Niseko area (and to raise money), the Japanese hierarchies sold a significant proportion of the land to private investors, thus transforming the Hirafu area into a property hotspot. As a result, there are many people that have purchased private property (houses and apartments) as holiday homes. There are also many people who prefer to rent a house rather than to stay in hotels since there is much more freedom to explore the shopping and dining places. Meals are usually not provided if one chooses to rent houses. Although there is a satisfactory number of dining places, majority of these restaurants are Japanese, and more suited to lunch and dinner. That leaves the problem of the most important meal of the day: breakfast. Since there isn't any fancy breakfast buffet like you get in most hotels, they would have to cook there own breakfast, using raw ingredients from Seicomart. Despite the slightly higher prices, consumers wouldn't mind not being too frugal with their money. Overall, Seicomart trumps Lawson in the battle of convenience due to its location, as well as tapping into the needs of the consumers.

Another option is to head for the nearest train station town, Kutchan-cho (倶知安町). There, the town has a very large supermarket with a plethora amount of goods, much more substantial than Seicomart and Lawson combined. Aside from the supermarket, there are also several restaurants (ramen, yakiniku etc.), bookstores, and shopping malls to name a few. Even before that, how do people get there from Hirafu? There are only two options; either take a taxi (around ¥4000 for round trip), or the scheduled bus for ¥100 (free for return trip). Although the taxi is much faster, it becomes the 'marginal' choice in this case due to it not being economically viable compared to the bus.

"All aboard the big red bus!": Hirafu and Kutchan-cho bus link transport

Because the Niseko bus is perceived, and treated as a public transportation service, the price is generously low. It fits the requirements of a quasi-public good/service; the bus service is non-excludable, but is rivalrous since there are limited bus seats available. What I find most extraordinary is the ¥100 price. Are they hoping to be socially efficient? Is is in the nature of Japanese people to be altruistic? Maybe maybe not. Ski resorts are seasonal, so any type of producer should aim to maximize his/her profits before closing in the summer. With the price difference being so large, frugal consumers would almost always choose to ride the bus. Once the bus service has established its dominance as a necessity to those who wish to enter Kutchan-cho, we realize that our demand is very inelastic. So why not raise the price to ¥200, ¥300? It will undoubtedly still be less expensive than cabbing. The only plausible reason I could think of is that the comparison between Hirafu and Kutchan-cho is minimal in terms of necessities. Sure, Kutchan-cho has a large supermarket, but Seicomart and Lawson can meet all our necessities during our trip. Moreover, Hirafu also have many high quality restaurants, so there is no specific need to go there to savour delicious Japanese cuisine.

"Japanese cuisine under the culinary spotlight": Local Japanese restaurant along Hirafu main street. Appetizing appearances in harmony with the fantastic, fresh flavours.

So this gives rise to the question: what will I benefit from going to Kutchan-cho when everything I need is already in Hirafu? I will leave it to you to answer this one.

The next issue is equipment rentals. Renting snowboards, skis, and their respective shoes are fantastically expensive. Below is a link to the Niseko 'Ski Japan' rental prices:
http://www.nisekobase.com/rental-pricelist/

Let us focus on snowboarding. After researching various snowboard prices from experts, the average cost of a snowboard package is around $500 USD, or around ¥47200-¥47300 following the current exchange rate. Is it better to buy your own snowboard equipment or rent it? To start off, most people who snowboard are unlikely to view it as a one-off experience. Usually, failures from trying something could create an incentive to try again until they succeed. Judging from this possibility, it should be assumed that those who snowboard are likely to mark it as a long-term activity. Next, let us consider the rental price of 5 days (proper holiday should be around at least one week or so) of snowboarding for standard adults (¥22500). Taking the above prices, and the possibility of repairs on purchased boards, one would expect to more than cover the cost of buying a board by renting equipment only 3 times. Furthermore, by buying a board, you can guarantee its quality, and suitability to the individual's specification. Rent involves a temporary use of an asset. For short term usage, then renting is favourable. However, since we expect these activities to be long term, having ownership of a fixed asset becomes less expensive.

Immediately, we see that there is third-degree price discrimination between adult and child board prices (identical activity of different size, assume same quality and type, and no difference in supply). This price-discrimination arises from the amount of materials used to produce boards of different sizes, and the choice of activities available. For families with children, they could either send them to ski school, or if all of them have capable ability to ski/snowboard, then the family could ride the mountain routes together. The former scenario grants the parents with several activity choices (e.g. sight-seeing, horse-riding etc.) other than skiing/snowboarding, since their children are left in the care of certified instructors. However, the latter scenario narrows their choice to two; either proceed with the activity together, or not at all. Either way, a parents' top priority in a foreign country is to ensure the safety of their children. Given that the family spends so much money to come to a ski resort and not ski, is quite similar to paying for a prostitute but not having intercourse. Therefore, the adults' course of action is driven by their children, which is no surprise really. There is also a similar second-degree price discrimination because the the average price of renting the equipment decreases per day. These organizations are undoubtedly skilled in extracting consumer surplus.

So what about summer? Seasonality is once again playing it's natural, crafty role. When I went during the 2012 summer Hokkaido road trip, Hirafu was eerily quite. All the shops, hotels, and restaurants are closed for business, and the mountain slopes are being repaired. It feels like staying in a ghost town! Seasonal unemployment would increase initially in all the Japan ski areas for nearly all types of labour. Overtime, some of these labour would relocate to other ski areas, or other part-time occupations where their labour skills are utilized. For example, store clerks could find employment in other stores as salesmen/women, and ski instructors on the northern hemisphere can continue their jobs on the southern hemisphere, though the labour workforce demand is much less due to the lesser number of ski resort destinations compared to the nothern hemisphere. Nevertheless, we should expect employment increase in other industries during winter to summer transition. To combat the seasonality problem in the summer, people would shift the factor of production, mountain land, for other purposes. In Hanazono (花園), the small ski resort area to the east of Hirafu, their summer activity club involves mountain biking, rafting, hiking, golfing, canyoning, the zipline, and the infamous bag jump. Despite the attractive activities, since they marketed themselves as a ski resort, these activities become somewhat out-of place. There are many other places to do these activities for much cheaper prices; therefore, the need to go to Japan becomes obsolete. And because of this psychological mentality, it too is subjected to the effects of seasonality.

But as the saying goes, "all good things must come to an end." That's right, one week of snowboarding just flew by in the blink of an eye. On board the big tourist bus to New Chitose airport. The departure floor was full of souvenir shops, selling the local snacks I love. Personally, I think the best thing about these shops are that consumers could sample the snacks. Usually with all types of snacks, our sources of information are limited to the appearance and information on the packaging. It is important in gastronomy that we obtain information of the foods' sensory qualities (especially taste, smell, texture). In an economic sense, we as the consumers will have acquired more information about the goods in the market, hence narrowing the disparity of asymmetric information. That being said, almost all the snacks are so delicious that it does not matter whether I taste or not. Nevertheless, it is economically favourable to have more information of a product.

But even more interesting, is the competition between rival stores. The competition almost resembles perfect competition. This scenario is made possible from the homogeneous goods, identical prices, and same service. Actually, these stores act as retail wholesalers, and I have confirmed that all the goods come from the same producer, so we can assume that all the goods are of same quality. Below are some pictures of these shops.


For the second row of pictures, all the shiroi koibito, 白い恋人 (chocolate sandwich biscuits) are ¥1100. Then for the third row, the Royce Chocolate potato chips are ¥693, and Royce Chocolate popcorn are ¥525. From this, we can see that three different shops sell exactly the same goods for the same price. There is no choosing between them; you can pop into your closest shop, having the confidence and knowledge that whatever good, it is the same everywhere else. Or is it? If you happen to have time and someone who can carry a lot of things after you've gone through customs, then you could reap the benefits of less expensive duty-tax free goods.


 After the duty tax was alleviated, the Royce Chocolate popcorn is ¥500 (original price = ¥525), and the Royce Chocolate potato chips is ¥660 (original price = ¥693). Both goods become 4.762% less expensive.

Similarly, the 白い恋人chocolate biscuits is now ¥1058 (original price = ¥1100); meaning that the price decreased by 3.812%.

Well that is it for my Japan holiday. Thank you all for the continued support, and I hope you have enjoyed reading this, I must say, rather long post.

Tackling the IB Economics Examinations

At this point in time,  IB candidates sitting the May 2013 examinations (me included) would have finished their Economics exams. As mentioned on my blogs' most viewed page "IB Economics Syllabus", starting from this year, the format of each paper is different. So this page is dedicated to future IB Economics candidates so that when you enter the exam room on the fateful day, you are 100% certain on:
1. The Examination Techniques
2. The common but effective points
3. Key important points to use during the exam
