Final exam part 1 Flashcards
Closed system
a system where there are no inputs and no outputs of energy and matter from outside the system
open system
a system which imports or exports energy or matter from outside
positive economics
describing what is, what was, and what will be
normative economics
attempting to answer what ought to be
willingness to pay
reflects the “value”–> what an indiv. is willing to sacrifice
Willingness to pay or demand price for an additional unit is a measure of the…
marginal benefit from the unit
How can we allocate resources efficiently
by maximizing social welfare: maximized economic surplus= sum of consumer surplus and producers surplus
consumer surplus
measure of the net benefits accrued by buyres over all units purchased
producer surplus
measure of the net gains received by sellers over all units sold
social welfare equation
SW=CS + PS
in a competitive equilibrium, social welfare is…
maximized
Pareto optimal
allocations are pareto optimal if no other feasible allocation could benefit at least one more person without any deleterious effects on some other person
efficient and welfare maximizing outcomes occur even though C and P behave in self interest=
invisible hand
market failure
violation of any underlying assumptions and an inefficient allocation of resources
- indiv. incentives no longer lead to the efficient outcome
conditions for markets to produce efficient allocations (8)
- markets exist for all goods and services P + C
- perfectly competitive markets
- transactions have perfect info.
- private property rights fully assinged in all resources and commodities
- no extenalities
- goods and serivces are private goods
- all utility and production functions are well-behaved
- all agents and maximizers
Market failures
- externalities
- public goods
- imperfect comp.
- imperfect info.
- inappropriate govt intervention
property rights and environmental problems
for env. goods it is often unclear who owns the rights
efficient property right structures (3)
exclusivity, transferability, enforceability
exclusivity
all benefits and costs should only accrue to the owner
transferability
property rights should be transferred to others
enforceability
property rights should be secure from seizure or encorachment
if price fails to capture all benefits and costs=
market failure
negative externalities create a divergence between…
private and social costs equal to the external cost
Market equilibrium=
when MC=MB
as long as costs are external,
no incentive for firms to produce less pollution per unit of output
public goods
consumptively indivisible, non rival and nonexcludable
private goods question
what Q would you consume at each P? then sum up all Qs for each P
public good question
what price would you be willing to pay for each quantity of the public good? and then sum up all WTP values for each Q
