What is the difference between positive and normative statements? - Positive statements can be tested to see if they are correct, whereas normative statements cannot. Machinery is an example of what factor of production? - Capital Why are value judgements important? - So you can choose between options in a way most people think is fair Why does the fundamental economic problem exist? - People have unlimited wants but resources are scarce to make these goods People choose to _________ something - maximise When a choice must be made, what do people choose? - People choose what they think at the time is the best alternative What is the opportunity cost? - The cost of giving up the next best alternative Can someone act rationally and be wrong? - Yes, but they are only rational if they don't make the same mistake again If a point on a PPD moves closer to the PPF, what is this? - Short-run economic growth What are all the points on the PPF? - productively efficient Are all the points on the PPF allocatively efficient? - Not necessarily, as it may not be what people want. Allocative efficiency requires value judgements.
How is the equilibrium price set? - By interaction of buyers and sellers in a market What is the difference between effective and latent demand? - Effective demand is the desire for a good or service backed by an ability to pay, whereas latent demand is the desire for a good or service without means to pay.

What is the difference between market plans and market action? - Market plans are what you want to end up doing whereas market action is what you actually end up foing What is the difference between a shift of a supply/demand curve and the adjustment to a new equilibrium of these curves? - The shift of a curve is an increase or decrease of supply/demand because the good's price changes whereas the adjustment is an extension or contraction of supply/demand because the good's price doesn't change
