Final Terms Flashcards
MR=MC
marginal revenue = marginal cost
When do maximize behavior
when MR>MC you max behavior until MR=MC.
when do you stop maximizing behavior
when MC<MR when costs exceed revenue
why is trade good?
it can help you produce outside of your PPF.
comparative advantage
one person/company being able to produce things with less of an opportunity cost than others.
inelastic
Quantity demanded only changes a little when there’s a price change (people buy regardless)
elastic
Quantity demanded changes a lot when price changes (people may buy less or more depending on price change)
how to interpret elasticity
E=4, a 1% increase in price results in a 4% increase in quantity demanded
social planner objective
maximize surplus by getting rid of DWL
problems with externalities
They have a large cost against society that is bigger than the cost producers bear. (on a graph the optimum quantity is smaller than the equilibrium quantity)
solution to negative externalities
internalizing the externality, which means making the person responsible for external costs their negative externality may produce a tax on producers
problem with positive externalities
People are causing a good thing to happen with their positive externality but they should be getting compensation but they are over producing because they are not compensated enough.
solution to positive externalities
subsidize goods with positive externalities (government gives financial assistance or support to encourage goods that produce a positive externality)
complements
pairs of goods that are used together, increase in one = decrease in the other
substitutes
pairs of goods that are used in place of each other, increase in one = increase in the other
