test III: nature of economics Flashcards
economics
study of choices made by individuals and businesses
coordinated by markets and influenced by governments
most efficient ways to use scarce resources
macroeconomics
global view/ economy as a whole
impacts of choices on main economic indicators
microeconomics
how individuals and businesses make decisions (what influences choices) in a world of scarcity
supply and demand (bottom-up approach)
scarcity
wants exceed limited resources - need to make choices
choices
deciding to have more of something means to have less of something else
incentives
financial
social
moral
opportunity cost
we have to give up something (trade-offs)/ cost of decisions
production possibilities curve
represents all possible production combinations (choices) of two goods that can be produced + opportunity cost
- cash, time, labour, factory, equipment, transport and materials
- line represents scarcity
- economic growth when the line moves up
capitalist economy
free market, private ownership, self-interest, supply and demand, competition
command economy
planned economy, public ownership, production and price regulated by the state
supply and demand
law of demand: P up, Qd down
law of supply: P up, Qs up
E: Qd = Qs
non-price determinants of demand
price related goods expectations population income (normal or inferior goods) tastes and preferences
non-price determinants of supply
price expectations input costs nb of firms in the industry technology and productivity subsidies and taxes
simultaneous shifts: both supply and demand shift the same way
change in Eq is indeterminate, Ep is unambiguously
increase: increase in Q
decrease: decrease in Q
simultaneous shifts: supply and demand shift in different ways
Ep increase or decrease, change in Eq is uncertain
supply increases and demand decreases: increase in P
supply decreases and demand increases: decrease in P
