- when input prices rise → production becomes less profitable → firms produce less - if input rise substantially, a firm might shut down & produce no output at all 2) technology - advance of technology reduces cost of producing output → raises supply 3) expectations - if price is expected to rise in future, firms will put some of its current production into storage & supply less to market today 4) # of sellers - as # of sellers increase → market supply increases Change in Supply VS Change in Quantity Supplied increase in supply: supply curve shifts to right increase in quantity supplied: movement along supply curve decrease in supply: supply curve shifts to left decrease in quantity supplied: movement along supply curve Summary: Variables that Influence Sellers Exercise Draw a supply curve for tax return preparation software. What happens to it in each of the following scenarios? 1) Retailers cut the price of software. - supply curve doesn’t shift - there is a movement along supply curve to a point w lower P & lower Q 2) A technological advance allows software to be produced at lower cost. - supply curve shifts to right - at each price, quantity supplied increases
