Consumer sentiment
Is a mathematical measure of the health of the economy as indicated by consumer opinion
Rational consumer
Is a logical or reasonable consumer. He/she is able to make purchasing decisions using intelligent thinking rather than emotion.
UTILITY
refers to the benefit that an individual gets from consuming a good or service.utility is measured in [ utils] SATISFACTION
TOTAL UTILITY
refers to the total benefit that an individual gets from consuming a number of units of a good or service. TOTAL SATISFACTION
MARGINAL UTILITY
refers to the extra benefit that an individual gets from consuming an extra unit of a good/service EXTRA CONSUMPTION OF A UNIT
CONSUMER SENTIMENT
is a mathematical measure of the health of the economy as indicated consumer opinion
CONSUMER BEHAVIOR
while no two consumers are the same,economists and policymakers make some generalizations or assumptions when formulating economic models about the way that consumers behave
Impulse purchase
Is a purchase that is made on the spur of the moment that the consumer had not planned in advance.
Economic good
Is transferable and is scarce relative to the demand for it
The Law of Diminishing Marginal Utility
The Law of Diminishing Marginal Utility (LDMU) states that as a consumer consumes more units of a good, the extra satisfaction or marginal utility derived from each additional unit consumed will eventually decline.
The Law of Equi-Marginal Returns
The Equi-Marginal Principle of consumer behaviour states that a consumer who wants to maximise utility will allocate his or her limited income so that the ratio of marginal utility to price (the marginal utility per euro spent) is the same (equal) for all goods he or she consumes, i.e
Marginal utility of good A
—————————————-
Price of good A
=
Marginal utility of good B
—————————————-
Price of good B
Price elasticity of demand (PED)
Measures the percentage change in the quantity demanded of a good/service as a result of a percentage change in the price
Relatively elastic
Demand for a good is relatively elastic if the percentage change in price is outweighed by the percentage change in quantity demanded.
Relatively inelastic
Demand is relatively inelastic if the percentage change in price outweighs the percentage change in quantity demanded
Unitary elastic
Demand for a good/service is unitary elastic if the percentage change in quantity demanded is equal to the percentage change in price
