What is the Production Possibilities Curve (PPC)?	PPC represents all different combinations of how or how much two good can be produced by an economy, given its available resources, production efficiency, and whether there is a full employment of resources or not.

In terms of Economics, what is meant by a 'positive statement'?	A Positive Statement is a statement which can be tested empirically. Positive concepts involve something that is, something that was or something that will be. E.g. The unemployment rate is 5%.

What is a Law?	A statement that usually has a universal validity. Laws are usually based on theories.
What is a model?	Models represent important aspects of the real world being investigated, allowing social scientists to focus on important relationships. Models are often illustrated by the use of diagrams and mathematical equations.
What is Ceteris Paribus?	Means that all other things are assumed to be constant/unchanging. Ceteris paribus is useful when economists want to be able to isolate the effects of variables.
What is rational decision making?	Means that individuals are assumed to act in their best self interest, trying to maximise the satisfaction the expect to receive from their economic decisions.
What is meant by irrational decision making?	Irrational decision making are mainly based on emotions, without any consideration of the possibilities of the outcomes caused by the decision made.
Define Economic Growth	When Is an increase in quantity of output of an economy. This means more goods and services are being produced, therefore potentially increasing the country's standard of living.
What is negative economic growth?	Occurs when there has been a decrease in the quantity of output of an economy.
Define economic development.	Refers to raising the standard of living and well being of people. E.g. Reduction of poverty.
Define what is meant by sustainability.	Sustainability occurs when societies grow and develop without leaving behind fewer/lower quality resources for future generations. This can be achieved by increase use of renewable resources.
What is a market?	A means by which buyers and sellers come together to exchange goods and services.
What is meant by demand?	Demand refers to the amount of good an individual/consumer is willing and able to buy at a certain price, in a given time period, ceteris paribus.
What is the law of demand?	That there is a negative causal relationship between the price of a good and its quantity demanded over a particular time period, ceteris paribus.
Define marginal utility?	The extra benefit derived from each additional unit consumed.
Define market demand	Is the sum of all individuals demands for a good and consumers marginal benefits.
What is supply?	Supply is the quantity a firm is willing and able to produce and supply to the market at different possible prices, in a given time period, ceteris paribus.
What is the law of supply?	States that there is a positive causal relationship between price and quantity of a good supplied, over a particular time period and its price, ceteris paribus.
What is the market equilibrium?	The point where quantity supplied equals quantity demanded and there is no tendency to change.
What is the formula for the demand function?	Qd= a -bP Qd= Quantity demanded and is the dependent variable (depends on price) P= Price (independent variable) a= the Q intercept (Horizontal axes) -b = Slope calculated by change in Qd/ Change in P
What is the formula for the Quantity supplied function?	Qs= c+dP Where Qs= Quantity supplied, and is the dependent variable P= Price and is independent variable c= represents the Q intercept d= represents the slope calculated as: Change in Qs/ Change in P

What is a price elastic?	If there is a large responsiveness to quantity demanded.
What is price inelastic?	IF there is a small repsponsiveness of quantity demanded.
What is price elasticity of demand?	Is a measure of the responsiveness of the quantity of a good demanded to changes in its price. If the responsiveness is large, then the product would be classified as price elastic. If the responsiveness is small, then the product would be classified as price inelastic.
What is cross price elasticity of demand? (XED)	Is a measure of the responsiveness of demand for one good to a change in the price of another good, and involves curve shifts.
What is income elasticity of demand? (YED)	Is a measure of the responsiveness of demand to changes in income, and involves demand curve shifts. It is related to the direction of change of demand given a change in income (increase or decrease), and on the size of the change.
Define Price elasticity of supply (PES)	Is a measure of the responsiveness of the quantity of a good supplied to changes in its price. If there is a large responsiveness in the quantity supplied, then it is supply elastic. However, if there is small responsiveness in the quantity supplied due to a change in price, it is considered to be price inelastic.
What is an indirect tax?	Indirect taxes are imposed on spending to buy goods and services.
