Which do you prefer, the Wii? the XBox 360? the PS3? How about other video game consoles? Can you even think of any other video games consoles? Hmm… let’s see… how about the Sega? Wait, no, haven’t seen any of those in a while… what about the Atari? Oh, shoot, nope! Oh yeah, don’t forget the Caleco Vision (for the record, Mr. Welker’s earliest video game memory was of playing Smurfs on a Caleco Vision).

The fact is, today, the market for video game consoles has shrunk to three dominant firms: Nintendo, Microsoft and Sony. This podcast will investigate the video game console market, examine its characteristics, including the elasticity of demand for the different consoles, and conclude whether it exhibits the features of an oligopoly.

The links below will take you to an overview of several theories relating to exchange rates. These include:

• Foreign Exchange Markets – James and Wan Jin
• Fixed exchange rates - Marco and Danny
• Floating exchange rates - Enno and Dennis
• The Marhsall-Lerner Condition – Manon, Kaj, Daniel
• The economic effects of a devaluation – Carlos and Lucas

Your assignment in today’s class is to work with your partner to read and prepare a short presentation of your assigned topic. You will come to the front and explain your topic halfway through class.

BBC NEWS | Business | Supermodel ‘rejects dollar pay’

Currency speculators should take note… the world’s highest paid supermodel has sent a clear signal to those buying and selling currencies in the foreign exchange markets: The US dollar is NOT a good buy!

How does a woman who made $30 million in the first six months of this year send such a signal? By refusing to accept modeling contracts offered in US dollars, insisting she be paid in Euros.

The question is, why does she care what currency she’s paid in; can’t she just convert it to whatever currency she wants once she’s paid? According to Tim Harford, the “Undercover Economist”:

It seems she believes that the dollar is likely to fall in the short term, between the time a contract is agreed and the money is paid. (In the long term, who cares? She can convert her cash to any currency she likes.)

The weak dollar is clearly of concern to Americans consumers and foreign producers alike, but it’s more than likely that Gisele, while she may be the queen of the catwalk, probably knows more about striking the perfect pose than she does about behavior of foreign exchange markets.

The Big Mac index | Economist.com

In IB Economics we’re studying the theory of exchange rates. A floating exchange rate system should be in equilibrium when the rate enables people in different countries to buy the same basekt of goods with an equal amount of money. In other words, If I walk into McDonalds in the US and have to pay $3.00 for a Big Mac, then board a plane, land in Shanghai and walk into a McDonalds there, the price I pay in Shanghai should, given current exchange rates, be the same as what I paid in the US. In reality, a Big Mac in Shanghai costs about 56% less than one in the US. This tells economists something about the value of the Chinese RMB. Continue Reading »

Wetpaint, the free online wiki service, has stepped up its use of non-price competition in an attempt to increase its market share in the wiki market. In addition to releasing several Mac vs. PC parody videos meant to showcase the user-friendly, customizability of Wetpaint’s wikis vs. its rivals, the company also announced this morning that it would be offering ad-free wikis to educators!

As a user of Wetpaint since early this year, the distracting presence of advertisements bothered me; the decision to provide educators with ad-free wikis is huge, and makes Wetpaint even more attractive as a platform for hosting online learning communities for teachers of all grade levels.

You may be thinking, “Huh? There’s a market for wikis?” Well sure there is. Just because something’s free for us consumers does not mean it’s not a profit oriented business. Wetpaint and its rivals compete for consumers in an oligopolistic market in which competition is not based on price (since its products are essentially free), rather on product differentiation based on features and communicated through advertising and public relations.

Oil worker shortage could lead to supply squeeze – Nov. 2, 2007

Lately I’ve blogged about the impact of higher oil prices on the petrol market in China (here and here). As the main input in petroleum products such as gasoline and diesel, the price of oil affects the costs of fuel producers, such as China”s SinoPec and PetroChina, the two large state-owned petroleum companies, as well as the scores of smaller competitors in that provide fuel to China’s thirsty economic machine.

As the price of oil has approached $100 per barrel, fuel manufacturers have had to cut back output as their costs have soared, putting upward pressure on the market price of fuel here in China. But what determines the price of a barrel of oil? Is the increase in the price of oil due to an outward shift of demand or an inward shift of supply? Actually, it’s probably both. This article helps answer part of our question, and it does so by discussing one of the determinants of supply of oil, resource costs. Continue Reading »

FT.com / Asia-Pacific / China – Pressure builds over renminbi

In IB Economics, we’re currently studying the determinants of exchange rates. One important factor in determining the demand for a particular currency is the interest rates in the country whose currency is in question relative to that of other countries.

The recent cut of the federal funds rate in the US of 25 basis points to 4.5% brought the US rates closer to China’s recently increasing interest rate of 3.32%. The upward trend of Chinese rates (up 50 basis points this year) and downward trend of American rates (down 50 basis points this year) should diminish the appeal of dollar denominated financial assets and increase the demand for those in Chinese RMB. In the currency market, we should see weakening demand for dollars and strengthening demand for RMB, as US savings and government securities are relatively less appealing due to the declining returns on those investments. With further increases in Chinese rates expected (due to high inflation), the RMB should be in greater demand, as returns on Chinese investments looks to increase as rates rise. Continue Reading »

xkcd – A webcomic of romance, sarcasm, math, and language – By Randall Munroe

Well, not exactly, but that’s kind of a dramatic headline, isn’t it? The other day I blogged about the demand". Occurs when the price is below the equilibrium level, for example, when a government imposes a price ceiling in a market.');" onmouseout="tooltip.hide();">shortages experienced in the petrol market in eastern provinces, evidenced by the long queues at gas stations around Shanghai last weekend.

Petrol stations resorted to rationing their product in small doses (between 20 and 40 litres) as the price of oil hit $92 and Chinese refiners scaled back production due to rising costs that they were unable to pass on to their customers. Beijing had previously imposed a price ceiling on fuel in an attempt to keep inflation low and Chinese consumers content; the actual impact of this price control was predictable: not enough fuel to go around as the quantity demanded exceeded the quantity supplied, leading to shortages and rationing at the pump.
