1.2 How markets Work Flashcards
what is utility?
Utility is the measure of satisfaction?
what does marginal mean?
additional
what does the law of marginal utility mean?
this law states that as the amount of a commodity increases. the utility derived by the consumer from the additional units decreases.
total utility
the total satisfaction from a given level of consumption
marginal utility
the charge of satisfaction from a given level of consumption
what makes an expansion in demand occur?
when price falls
what makes a contraction occur?
when price increases
what causes a shift in the demand curve?
a factor other than price changes
what factors cause a change in supply?
-changes in price of substitutes in competitive demand
-changes in the complements
-changes in the real income of consumers
-changes in distribution of income
-effects of advertising and/or marketing
-interest rates
-change in population
-seasonal factors
-social +`emotional factors
which way does a decrease in demand shift?
left
which way does a increase in demand shift?
right
which way does a reduction in supply go?
left
which way does an increase in supply go?
right
what does the supply curve show?
how much of a product producers will supply onto the market at each price
Factors that affect the supply curve
-changes in cost of production
-natural factors
-government taxes and subsidies
-change in technology
what does it mean to be elastic?
Where % change in demand is greater than % change in price
what does it mean to be inelastic?
where % change in demand is less than % change in price
When is it equilibrium?
when demand and supply are equal
what makes a shortage occur?
if the price is lower than the equilibrium price then there will be a shortage of the good because firms will want to supply less onto the market than consumers want to buy
what makes a surplus occur?
if the price is higher than the equilibrium price then there will be a surplus because firms will want to supply moreonto the market than consumers want to buy
derived demand
the demand for a product is derived from the demand for another product
price elasticity of demand
the responsiveness of demand to changes in price
price elastic
where % change in demand is greater than % change in price
price inelastic
where % change in demand is less than % change in price
