Answer to Question 1

Public goods are non-rival and non-excludable. Everyone consumes the same quantity of a public good. The market demand for public goods is derived by summing individual demand curves vertically. Individual demand curves need to be summed vertically because this shows the amount of money consumers are willing to pay for each level of the public good.
