Solution: When there are no externalities, a competitive market achieves economic efficiency. If there is a negative externality, economic efficiency will not be achieved because:
a) too much of the good will be produced
Explanation:
Negative externality are the expenses borne as a result of some economic event or transaction.
In negative externality, all costs are not paid by the producer which leads to overproduction or excessive production of a good. When all the costs are taken into account, the prices of good is much higher and less people consume it as demand decreases. Whereas in positive externality, too little of the good is produced as production is decreased.

Which of the following is TRUE of market failures? Externalities and public goods are examples of market failure. O All of the answers given are true of market failures. O When our resources are not allocated efficiently by the market, then we have market failure. Markets characterized by monopolies, oligopolies and monopolistic competition are examples of market failure. Statement 1: If left to itself, the market will produce too little of a good if there are positive externalities. Statement 2:...

I don't understand deadweight loss. I thought it was the surplus
that was lost from a shift. Why isn't the area I shaded red also
deadweight loss? It was originally producer surplus and it's now
above the demand curve, therefore it's no longer anyone's
surplus.

An environmental economic consulting firm is hired to measure the negative externalities associated with the pollution from an industry. The consultants calculate the marginal social cost of production to be MSC-2Q+30 and the marginal private cost of production to be MPC-+30. The market demand curve for the industry can be expressed as P- 60-Q. If the industry currently does not take into account the negative externality in its supply decisions, the industry is the social optimum. a) under-producing; 5 b)...

TRUE OR FALSE To maximize welfare in a competitive market that has a negative externality in production, government should tax a pollution-generating good at a unit tax equal to the marginal cost of the externality. If there is deadweight loss, we say a market failure has occurred. If two identical firms behave according to the Stackelberg model, the joint production is higher than if the same firms act as a Cournot. The outcome of the Stackelberg model is a Nash...
