Econ Midterm #1 Flashcards
Scarcity
the condition that arises bc wants exceeds the ability of resources to satisfy them (we must choose among available alternatives)
Economics
is the social science that studies the choices that individuals, businesses, and governments make as they cope with scarcity, the incentives that influence those choices, and the arrangement that coordinate them.
Microeconomics
the study of the choices that individuals and businesses make and the way these choices interact and are influenced by governments.
Macroeconomics
the study of the total effects on the national economy and the global economy of the choices that individuals, businesses, and governments make.
Economic ?’s
- How do choices determine what, how, and for whom goods and services get produced?
- When do choices made in self-interest also promote the social interest?
goods and services
are objects and actions that people value and product to satisfy human wants
what
goods and services get produced and in what quantities
How
goods and services get produced and in what quantities
For whom
are the various goods and services produced (this depends on the income that people earn and the prices they pay for goods and services)
Self interest
choices that are best for the individual who makes them
social interest
the choices that are best for a society as a whole
trade off
an exchange (giving up something for something else)
Opportunity cost
is the best thing that you must give up to get something – the highest valued alternative forgone (example: professor gives up spending time with family in order to teach)
marginal cost
is what you must give up to get one additional unit of it
Marginal benefit
is the what you gain when you get one more unit of something (is measured by what you are willing to give up to get one additional unit of it)
normative statements
disagreements that cant be settled by facts
positive statements
disagreements that can be settled by facts
cross section graph
shows value of an economic variable for different groups in a population at a point in time
Ex: a graph that shows SAT scores of male and female students in 2012 is a cross section graph
ceteris paribus
“other things remaining the same”- this assumption is used when graphing a relationship that involves more than two variables
production possibilities frontier
boundary between the combination of goods and services that can be produced and the combinations that cannot be produced given the available factors of productions and the state of technology
production efficiency
a situation in which we cannot produce more of one good or service without producing less or something else
free lunch
- a gift or getting something without giving up something else
On a PPF there are 500 lb apple and 1200 lb bananas and at another point there is 300 lb and 1300 lb bananas the opportunity cost of producing bananas is
200 apples/ 100 bananas = 2 lb apples
economic growth
sustained expansion of production possibilities (when an economy’s resources increase, its production possibilities expand and its PFF shifts outward)
