Students have completed the study of market failure, including positive externalities.
While not entirely a problem, positive spillover effects benefiting society still makes private costs much more or private benefits much less than their social counterparts. While it is true that society gains because of the positive spillover effects, there is still welfare loss as somebody else is still paying for the additional benefits.
Students have also mastered solutions of positive externalities of legislations, direct provision, positive advertising and subsidies.
Students will now be preparing for the examinations in the next week.
