Extracted text: Explain the difference between a positive and a negative network externality. A network externality for a good is positive if O A. the substitution effect of a price change is larger than the income effect, but a network externality is negative if the income effect is larger than the substitution effect. B. consumption by others decreases a typical consumer's marginal utility from consuming the good, but a network extemality is negative if consumption by others increases a typical consumer's marginal utility from the good. c. the price is lower the more people own it, but a network externality is negative if the price is lower the fewer people own it. D. the quantity demanded is higher the more people own it, but a network externality is negative if the quantity demanded is lower the more people own it. O E. it has a complement, but a network effect is negative if it has a substitute. Give an example of each. An example of a positive network externality is the dermand for A. a work of art for exclusivity, and an example of a negative network externality is the demand for a work of art for status. B. a toy to indulge a fad, and an example of a negative network externality is the demand for computers whose intrinsic value increases with other users. O. clothing to be in style, and an example of a negative network externality is the demand for a specially-designed sports car for prestige. OD. made-to-order clothing for status, and an example of a negative network externality is the demand for a lift ticket with lines. E. entry to an amusement park with congestion, and an example of a negative network externality is the demand for clothing because almost everyone else has it.
