Unit 1 Flashcards
What is the science of scarcity?
economics, achieving maximum value from deployment of scarce/limited resources… way of thinking about choice… broad concept
What is Opportunity cost
The value of the consequences forgone by choosing to deploy resources in one way rather and in best alternative use “sacrifice” “forgone benefit”
How does PPF represent scarcity?
Limited amount of resources, can’t obtain a perfect output (ex:only 24 hours in a day)
How does PPF represent choice?
shows combinations of choices we can make (ex: study time and non-study time that are attainable within a single day)
What is the cost benefit principle?
Take an action only if the extra benefits exceed the extra cost
What are the three types of efficiency?
technical, cost effectiveness, allocative
What is technical efficiency?
Producing maximum possible amount of output from the inputs used, given the chosen production method
What is cost effective efficiency?
producing a good using least cost method of production from among all technically efficient methods
What is allocative efficiency?
Using limited resources to produce and distribute goods and services in accord with the value individuals place on those goods and services
What is consumer sovereignty?
People are best judges of their own welfare, consumer preferences determine supply side action
What is the Pareto Criterion?
Criterion to test allocative efficiency, it is impossible to reallocate resources in a way that makes at least one person better off without making someone else worse off (all points on GUPF are allocatively efficient)
What is Potential Pareto Criterion?
If the gains from reallocation are sufficiently large that the winners could (in theory) compensate the losers and still be better off, policy is deemed allocatively efficient (seeks to maximize net benefit)
What is Marginal benefit?
The increase in benefit as a result of increasing production (or consumption) by one additional unit
What is diminishing marginal utility?
consuming more of a good increases utility but at a diminishing rate
What is marginal cost?
cost of one more unit of output/consumption; the increase in cost as a result of increasing production/consumption by one unit
What is marginal benefit?
Benefit from one more unit of output/consumption; the increase in benefit as a result of increasing production/consumption by one unit
What shifts demand?
- consumer preferences
- prices of related goods (complements/substitutes)
- income
- number of potential buyers
- expectations of price changes
What is the shape of demand curve?
Downward sloping, depicts relationship between price of a good and quantity of good demanded, other determinants constant
What are complement goods?
Goods that are normally consumed together so that an increase in the price of one causes a decrease in the demand for the other, and a decrease in the price of one causes an increase in demand for another
What are substitute goods?
good that can satisfy a similar want so that an increase in price of one increases demand for the other and a decrease in the price of one causes a decrease in the demand for the other
What are normal goods?
a good which quantity demanded increases as income rises, positive income elasticity of demand
What are inferior goods?
a good for which the quantity demanded decreases as income rises, a good with a negative income elasticity of demand
What affects supply?
- price of other goods
- number of sellers
- input prices
- technology
- expectations of price changes
What is Hurley’s framework of well functioning markets?
- conditions in the broader environment
- acceptance of willingness to pay
- technical conditions within the market
i) an absence of market power
ii)symmetry of information
iii) absence of externalities
