If firms face accurate market signals or incentives, markets will lead to efficiency

I am picking up the market for hogs and the market for education.

a) Market for hogs where a lot of pollution is created results in market failure due to the negative externalities that are generated by the hogs market. Since the market signals are not accurate in the sense that firms do not have to pay the cost for negative externality in the form of pollution that it is creating. Thus, the market will lead to more than efficient production of output and the cost of pollution is borne by the consumers in society. Thus, more than the right level of output is produced. Right producers are involved as only hog producers produce the output but with no restrictions or penalties on their production. Right consumers are not there as the cost of pollution is borne by those also who do not consume hogs.

b) Education is generally categorized as a merit good especially primary education as the benefits it confers to the society is more than the personal benefit that an individual gain by taking education. Education being merit good is often produced at less than optimal level and is rivalrous and excludable in nature. The education services are often provided by private players at a high cost and thus eliminate many people from reaping its benefits. Thus, less than the efficient level of output is being produced with limited producers in the market and also limited consumers as many of them are excluded due to the high cost of education.
