tiny 2 Flashcards
substitutes
g&s that can replace each other to satisfy the same/similar need
complements
g&s that tend to be used together to satisfy a particular want
competitive supply
compete for use of same resources
producing one implies decrease in other
supply
joint supply
produced in same production process
not possible to produce more of one without producing more of other
inferior g&s
g&s where demand falls as income increases
more affordable substitutes for more expensive g&s
normal/superior g&s
g&s where demand increases as income increases
luxury g&s not deemed a necessity for living
supply shocks
sudden and unpredictable events that affect supply
can be beneficial/adverse
price control
the setting of market P by gov so P are unable to adjust back to their problematic equilibrium level determined by D and S
unit tax
a specific amount of tax is imposed on each unit of a g&s
externality
consumption or production that gives rise to pos or neg effects on others whose interests are not taken into consideration
negative externality
action exerts negative effects known as external cost on third parties but no compensation is paid
divergence between private and social cost
positive externality
action exerts positive effects known as external benefits on third parties but no payment received
divergence between private and social benefit
private cost
cost borne by economic agents taking action
external cost
cost borne by other economic agents (non-decision makers)
social cost
cost borne by society as a whole
private good
rivalrous and excludable in consumption
impure public good
non-rivalrous and excludable in consumption
excludable
can prevent people from consuming the g&s once it has been produced
usually done by charging a price for the g&s
free-rider problem
once the g&s are produced, consumers who have not paid can still enjoy the benefits of public g&s
production possibility curve
show all max combo of g&s that can be produced by an econ in a given period of time when all resources are fully and efficiently utilised
ceteris paribus: state of tech is fixed
show potential output
scarcity
problem that arises when we want more than we have
opportunity cost
highest-valued option forgone
what to produce
choice of the types and quantities of g&s to produce
how to produce
choice of production methods
for whom to produce
who can enjoy how much of g&s
circular flow
visualise and understand how a nation’s overall econ works and how the flow of money goes
injections
money flows pumped into the econ
leakages
money flows leaked out of the econ
investment
the expenditure by firms on capital to produce more g&s
demand
various planned Q a consumer is willing and able to buy at different possible P in a period of time, ceteris paribus
quantity demanded
Q of a g&s a consumer is willing & able to buy at a particular P
law of demand
when P increases, Qd decreases, vice versa, ceteris paribus
supply
various planned quantities a producer is willing & able to produce & supply to market at different possible price in a period of time, ceteris paribus
quantity supplied
Q of a g&s a producer is willing & able to produce and supply at a particular P
law of supply
when P increases, Qs increases, vice versa, ceteris paribus
market equilibrium
no tendency to change
Pe: Qs = Qd
Qe: Q at Pe
quantity transacted
actual Q bought & sold
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
shortage
excess D
Qd»_space;> Qs
surplus
excess S
Qd «< Qs
