Title : Externality Introduction Of Externality.

Externality can involve either third party cost which is the negative externality or third party benefits positive externality. Negative externalities occur when a decision or activity imposes cost on anyone who are not involve in making decision. Next, every decisions involves some cost to the decision-maker which is private cost of your choice. In other way, the decision imposes costs on others as well, which would be the external cost. More than that, social cost is the cost to all members of society or the sum cost to the decision-maker (private cost) and to others

Postive Externalities.

Positive externalities are the benefits resulting from an economic activity that are enjoyed or a crew to third parties not the buyers, not sellers but third parties. Next, markets like education and healthcare generate positive externalities and the problem is that if we leave things to the mechanism, the forces of demand and supply we wont get enough of these goods thats where the market failure is. Other than that, market forces will only generates so much of these good when a larger level of an output would be good for society and government have to correct that.

Growth, first of all it has a downwards-sloping marginal private benefits curve. What this means is the marginal private benefits, private benefits are the benefits that enjoyed by the buyers and services in an economic activity and marginal

Other than that, the marginal social benefits of downwards sloping. There is no distinction between private and the social benefits in the negative externality diagram. Next, there is a distinction between the castes marginal private costs upwards slowly creates an equilibrium point Q1 which represents the market generated on level on out. That’s how the level of amplitude will be created things to market forces. More than that, they wouldn't pursue more than this because the next unit will create more cost environment so even when only considering private costs and benefits Q1 is the level output will be generated by the process Meccan this is market fading because we should also consider the external costs which we act the private past and this gives us a parallel social costs curve which is higher by distance of vertical distance. equals to the external costs higher than the private costs. It will have a new equilibrium position and a new powerful Q2 which is socially optimal. The best level an output for society but we have market failure is the market gives us Q1 too much every unit between Q2 and Q1 generates more customs benefits and we can see that the diagram which is the summation of all the units of outputs hast exceeding benefits-cost exiting benefits. Next, overproduction caused by the failure of market mechanism and label this the welfare loss to society is the
