1. Because they are they only supplier of PS3s. The assertion that theres always a supply curve is a simplification for entry level grade school economics. In this case the Supply curve is the Average cost curve or Marginal Cost vs Marginal Revenue curves. There is no specific supply curve. Which one you choose depends on whether you consider the console market to be a competive/monopolistic or an oligarchy. (my memories of these concepts are a little fuzzy) 2. Elasticity of Demand is this: Its the percentage change in quantity demanded divided by the percentage change in price. A good for which overall revenue rises as the price drops (approaches mass market price for the concept most used here) is elastic. A good for which overall revenue falls as the price drops is inelastic. If you want to show higher demand you would simply have the Wii demand curve shifted upwards and to the right of the PS3/360 demand curve, meaning more people would demand the Wii at every price point. |
Forgive me, as I've only taken Macro. Thus, i infered everything from what I know if you want a back story.....
- No, there will be a supply curve. As the definition goes "The willingness and ability of sellers to produce and offer to sell different quanities of goods at different prices during a specific time period." Sony is willing (or not) and able (or not able) to produce PS3s. Becuase of this, their output of PS3s is the supply curve. So, yes, there is one. It would work since Wiis have changed in supply. So, like I pointed out, the curve would shift. If you show me a site with some of this info, I might be able to see your line of thinking.
- Revenue is a by product of elasticity, not the cause or the main players. Here is how it reads "If demand is inelastic, the precent change in quanity demanded falls but by a smaller percentage but by a smaller percentage than the precent present rise in price. As a result, total revenue increases." Note the phrase in bold. The revenue is a result. Your still right, but the graphs need to be constructed based on how the consumers demands the product, not on the revenue. From what I've read, these graphs work, but are simplistic (they always were). The Wii is not that inelastic on the way down. The PS3 and 360 would also hold true as, appose to what you said, they do not sell any better at a mass market price. Becuase of that, they will not greatly increase quanity demanded when the price falls. of course, with the PS3, it is true that it got a strong push from the first price drop. Combining these two peices of information, I constructed the graph, and it coiencides with what I have read.
- Upward sloping demand would imply that as Wiis increase in price, they also increase in demand. This would not work as no price sells more when it's more expensive (tell one item that sold more when price went up. Even when gas went up, people found ways to waste less gas).
