price elasticity of demand PED
the responsiveness of a quantity demanded for a product to a change in its price %changeQd / %changeP
income elasticity of demand YED
the responsiveness of quantity demanded for a product to changes in the price of another product %changeQd / %changeY
elasticity of supply
the responsiveness of a quantity supplies of a product to change any of its determinants
price elasticity of supply PES
the responsiveness of a quantity supplied of a product to a change in its price %changeQs / %changeP
determinants of PED
factors that influence whether the demand for a good or service is elastic or inelastic with regard to a change in the price
