The Coase theorem states that     if transactions costs are low, property rights are assigned, and parties understand how much they value something, private bargaining will result in an efficient solution to the problem of externalities.     government intervention is always needed if externalities are present.     a free market equilibrium is the best solution to address externalities.     assigning property rights is the only thing the government should do in a market economy.

Give an example for a negative or positive externality and explain the inefficiency this negative or positive externality might cause. How should the government deal with this negative or positive externality? (regulation, taxes, subsidies, private remedies, etc.) What would be the most appropriate remedy for your example?

An intermediate microeconomics question

The market for seasonal flu shots is depicted in the graph. As more people receive flu shots, fewer people catch the flu and potentially pass it on to others. Therefore, the chance of catching the flu decreases for everyone, even those who do not purchase a flu shot. This is an example of a positive externality. The graph contains the private demand curve (D1) and the supply curve. D1 does not take into consideration the social benefit of people getting flu shots. Graph the social demand curve by placing the end points of D2 at the correct locations. Then, indicate the dead weight loss to society by placing the DWL triangle in the correct location on the graph.
