Document Summary

Practice problems chapter 1: information on the quantities that would be purchased at different prices, holding all other factors constant in a given time period from a group of firms is shown in a: Market demand curve: the demand curve"s usual slope implies that consumers: Buy less as the price of a good is increased: a firm"s demand curve is usually. More elastic than the market demand curve: the elasticity of per capita demand with respect to population is zero, then a 10 percent increase in the population will cause the quantity demanded to. 0. 50: the demand for office chairs in thousands is q = 80 -p2. 0. 5: if the price is when the price elasticity of demand is -1 then the marginal revenue must be: 0: the marginal cost of producing a paperback is half the marginal cost of producing a hardback version sold to consumers at four times the paperback price.

Demand curve:

The demand curve is the graph depicting the relationship between the price of a certain commodity and the amount of it that consumers are willing and able to purchase at any given price. It is a graphic representation of a market demand schedule. The demand curve for all consumers together follows from the demand curve of every individual consumer: the individual demands at each price are added together, assuming independent decision-making. Demand curves are used to estimate behaviors in a competitive market and are often combined with supply curves to estimates the equilibrium price. Demand curves are usually considered as theoretical structures that are expected to exist in the real world, but real-world measurements of actual demand curves are difficult and rare.

The demand curve will move downward from the left to the right, which expresses the law of demand.

If the price of corn rises, consumers will have an incentive to buy less corn and substitute other foods, so the total quantity of corn consumers’ demand will fall. The degree to which rising price translates into falling demand is called demand elasticity or price elasticity of demand. If a factor besides price or quantity changes, a new demand curve needs to be drawn. For example, say that the population of an area explodes, increasing the number of mouths to feed. In this scenario, more corn will be demanded even if the price remains the same, meaning that the curve itself shifts to the right.          

According to my view, the demand curve for the Apple Video iPod will increase. According to the given paragraph iPod is thinner and lighter. The hardware and software ecosystem offers good content options and also portable. These are the main qualities expected by the customers. Henceforth customer wants to buy this product in the future also. If the price of the product increases in the future the demand for the product also increases because customers demand more products thinking of price increase in the future. At the same time if the price decreases in this case also customers will buy the product because they think that the good product is coming at a reasonable price. The demand curve for Apple Video iPod in the future may be like follows.

What is your opinion on a competitor product which has similar features to that of an i-pad or say it is better than i-pad and is offered at a comparatively cheaper price, how this will affect the i-pad demand curve and why?
