Incentives- for competitive markets to work efficiently economic agents must respond to Price signals in the market
Price mechanism are decisions of consumers and businesses interact to determine the allocation of resources. the free market price mechanism clearly does not ensure an equitable distribution of resources
Price signals are changes in price which act as a signal about how resources should be allocated. a rise in price encourages producers to switch into making that good but encourages consumers to use an alternative substitute product
Rationing is a rising price which can reduce the quantity demanded of a good or service
prices have a signalling function because the price in a market sends important information to producers and consumers
