demand supply and equilibrium Flashcards
what is market equilibrium
market equilibrium is a situation where for a particular good, supply is equal to demand. When the market is in equilibrium, there is no tendency for prices to change. We say the market-clearing price has been achieved.
what is demand
demand is the quantity of a good/service consumers are willing or able to buy at a given price in a given time period
what is the law of demand
there is an inverse relationship between price and quantity demanded (as price increases quantity decreases) vice versa
what are the two effects of demand
There are two effects responsible for the law of demand: income effect, which states that the higher the price, the less the household can spend on the good with the limited income it has,
and the substitution effect, which predicts that an increase in price makes the household substitute away from the good towards cheaper substitutes
what are the non price factors that can shift the demand curve-pacsfic-
