|
factors of production
|
land: all raw materials
labor: skilled to risk takers to special education
capital: machines, factories, etc.
entrepreneurship: "know how"
|
|
marginal cost
|
cost of consuming or producing one more unit
as you produce more, MC increases because of opportunity costs
not all resources are equally well suited
|
|
marginal benefit
|
benefit from producing or consuming one more unit
as you consume more, MB decreases
|
|
comparative advantage
|
if a person can perform the activity at a lower opportunity cost that anyone else
|
|

point that makes you "happiest" occurs at equilibrium
point where we cannot produce more of one good without giving up some other good that provides greater benefits
|
|
specialization and trade
|
increase amount of products
consume outside individual PPFs

produce more of one good but have to give up some of the other good
as the quantity produced of each good increase, so does the opportunity cost
slope of PPF
|

|
equilibrium
|
place where you have no incentive to leave
|
|
surplus
|
supply too high / price too high
causes price to fall

|
|
law of demand
|

|
expected future prices
|
If the price of a good is expected to rise in the future, current demand for the good increases and the demand curve shifts rightward.
|
|
income shifter
|
normal good -- demand increases as income Increases
inferior good -- demand decreases as income increases
|
|
law of supply
|
the higher the price of a good, the more quantity supplied

|
|
supply of loanable funds
