An externality arises when a firm or person engages in an activity that affects the wellbeing of a
third party, yet neither pays nor receives any compensation for that effect. If the impact on the
third party is adverse, it is called a
externality.
The following graph shows the demand and supply curves for a good with this type of externality.
The dashed drop lines on the graph reflect the market equilibrium price and quantity for this good.
Adjust one or both of the curves to refiect the presence of the externality. If the social cost of
producing the good is not equal to the private cost, then you should drag the supply curve to
reflect the social costs of producing the good; similarly, if the social value of producing the good is
not equal to the private value, then you should drag the demand curve to reflect the social value of
consuming the good.

You’ve invented a 3D fax machine. This cool technology is almost like a Star Trek teleporter. You can scan an object at one machine, which creates an exact copy at another 3D fax machine. It is so valuable that as more people use it, it becomes more valuable, and the price any given user is willing to pay increases in turn. Consider a scenario in which there are 12 possible users, who each value the fax machine at i*n, where i is the index of that user (from 1 to 12), and n is the number of other purchasing users. So, if no one buys the 3D fax machine, everyone values it at 0. However, as soon as one person buys the device, then the 12 possible users begin to value the product at 1, 2, … 12, respectively. If 2 people purchase, the 12 possible users’ valuations increase to 2, 4, … 24, and so on. Because…arrow_forward3:01 2.
