36
market equilibrium
no tendency to change Pe: Qs = Qd Qe: Q at Pe
37
quantity transacted
actual Q bought & sold
38
price mechanism
the process by which P increase or decrease as a result of changes in D and S coordinates consumption and production decisions as an invisible hand
39
shortage
excess D | Qd >>> Qs
40
surplus
excess S | Qd <<< Qs
41
market
where producers and consumers take place to exchange g&s
42
competitive market
a market with many individual and small sellers and buyers no one in the market have the power to influence P of g&s P affected by D and S
43
marginal benefit
extra benefit from consuming additional unit of good | downward-sloping bc consumers are willing to pay less for each additional unit
44
consumer surplus
pos diff between maximum amount willing to pay and amount actually paid
45
marginal cost
firms’ extra cost of producing additional unit of g&s | upward-sloping because each unit more costly than the last
46
producer surplus
positive difference between amount actually received and minimum amount willing to accept
47
social surplus
CS + PS
48
allocative efficiency
achieved when market allocates resources so no one can be better off without making someone else worse off MB = MC
49
welfare loss
loss of SS in society when resources are not allocated efficiently
50
price elasticity of demand
measures the responsiveness of Qd to a change in its P | % change in Qd/% change in P
51
price elasticity of supply
measures the responsiveness of Qs to a change in its P | % change in Qs/% change in P
52
indirect taxes
taxes on spending on g&s paid partly & indirectly by consumers but paid to gov by producers suppliers can shift tax burden to consumers by ↑ P
53
free market
P of g&s freely determined by D and S
54
government intervention
any action carried out by gov that affects market econ with the objective of impacting consumption and production decisions
55
price ceiling
legal maximum price set by the gov below the equilibrium price that producers can charge on a g&s
56
price floor
legal minimum price set by the government above the equilibrium price that producers should charge on a g&s
57
subsidy
financial assistance from the government
58
socially-optimum outcome
no externalities MPB = MPC and MSB = MSC no difference between benefits to consumers and to society and costs to producers and to society allocative efficiency achieved
59
market failure
failure of the market to allocate resources efficiently
60
demerit good
g&s considered to be undesirable to consumers | over-provided by free market
61
