how markets work Flashcards
objective of consumer
maximise their economic welfare (utility/ satisfaction) from consumption by correctly spending their income
objectives of firms
maximise profits by producing at the lowest cost
dividend are then played to the shareholders
objectives of the government
maximise social welfare of the citizen
demand meaning
the ability and willingness to buy a particular good at a given price over a given period of time
causes of shifts in the demand curve
change in price of substitute
change in price of complements
change in real incomes
changes in the distribution of income (equal distribution causes more demand as poorer people spend more)
effects of advertising and marketing
change in regulation
interest rates
demography changes
seasons
trends
law of diminishing marginal utility
the utility from consuming an additional unit of a good will decrease as more of a good is consumed
consumer surplus meaning
difference between what consumers are willing and able to pay and what they actually pay
derived demand meaning
demand for the FOP to produce another good or service
price elasticity of demand (PED) meaning
the responsiveness of demand to a change in price of the good/ service
%change in quantity demanded/ %change in price
relatively elastic PED
PED more than 1
relatively inelastic PED
PED less than one
factors affecting PED
number of close substitutes available
price of product relative to total income
cost of substituting between different products
brand loyalty and habits
necessity or luxury good
addiction
If u need it now or had time to think
why firms use PED
the effect of a change in price on total revenue
changes in tax and weather the firm can pass on the cost to the consumer
price discrimination- can charge higher prices for the good when its needed and less when its not
EV for PED
not complete data
consumer demand changes over time
PED varies by time and region
not all firms profit maximise
elasticity will vary with each product
substitutes will change market strategies
cross elasticity of demand (XED) meaning
responsiveness of demand for one product to the change in price of another product
income elasticity of demand (YED) meaning
responsiveness of demand to a change in income
inferior good number and explanation
YED less than 0
rise in income will lead to a fall in demand for the good
normal good number and explanation
YED more than 0
rise in income will lead to a rise in demand for the good
