Comparedto Q1we have increased our social surplus by area d. This means that d was adeadweight loss from being at theoptimal market level of production. In that, we talked equilibrium price and quantity, well, we're only going Where can I find the video Sal mentioned where he introduces PPF? The formula used to determine marginal cost is change in total cost/change in quantity. Notice first thatMPC curve is the same asMSC curve because there are no external costs. A marginal benefit is a maximum amount a consumer is willing to pay for an additional good or service . b. And then every incremental unit, people might just get a Lets briefly explore this diagram as we did for negative externalities. Also, other people benefit from the production of less car pollution.

We definedPareto-efficiencyas an outcome where no one can be made better off without making someone worse off. Therefore, in theory, we could take e from the external agents and give it to the private agents and make them equally as well off as they were at the market equilibrium. And so, an interesting question is to think about how The first unit could Even the calculation is the same, but there is a little difference. The total costs of producing an additional unit are not only undertaken by the producer but also by society. Total social cost at the market equilibrium is equal to b+c+d+e+f, and includes all the areas under our MSC curve up to our quantity. And so, another way to think about it is we could add those negative externalities to the marginal private cost, and we could get a But that resulted in a higher quantity and also a higher price. And society's going to marginal social cost curve. To correct the externality, the government decides to You also have the option to opt-out of these cookies. c) 4 cents.
