Exam One Flashcards
simplified representation of the real world, shows how the economy works
model
theory not opinion
models are based in
other things equal/other facts are constant, holding other relevant factors constant/equal
ceteris paribus
theories and predictions hold
as long as assumptions hold
statistical analysis
how assumptions are tested
two goods case, shows options available for production of these two goods in different quantities
production possibilities model
given things in PPF
resources and technology
why PPF is concave
opportunity cost is not constant
endpoint of PPF
all resources are going to one production type
production efficiency and allocative efficiency, there is no way to make people better without others being worse, no missed opportunities
economic efficiency
combination along PPF line that is the best
production efficiency
picking the best combination for maximum satisfaction
allocative efficiency
who has the lower opportunity cost of production, could be different for each type of good, determines what people should trade and specialize in
comparative advantage
smaller trade off
best use of resources
direct exchange of goods and services
barter
not producing everything you consume
not self-sufficient
exchanges of resources, goods, and services, do it for the benefit of both parties, voluntary exchanges
trade
overall increased production of goods and services, more consumption possible
mutual gains
more consumption possible, increased satisfaction of wants, increased variety, lower prices for consumers
benefits of mutual gains
each concentrates on the tasks they are relatively better at, based on comparative advantage
specialization
output/labor
labor productivity
relative prices of traded goods, what people really gain in trade
terms of trade
when the terms of trade are greater than the opportunity cost
international trade continues
when the terms of trade are less than the opportunity cost
countries just produce their own goods
eliminating and restricting free trade
everyone goes down in satisfaction
ability to produce a good more efficiently than others, more output of a good per worker
absolute advantage
economics with judgement, not empirical, values a person has, can have disagreement about goals, based on ethical standards or norms, not testable
normative economics
economics with factual, empirical evidence, accepted relationships between variables, neither right or wrong, one correct answer, basis of economic analysis, testable
positive economics
representation of market system, flows of money, goods, and services, how they are channeled through the economy
circular flow diagram
households in circular flow diagram
act as consumers but also allocate resources
