supply elasticity = percent change in quantity supplied/percent change in price
When supply is elastic, a small change in price leads to a significant change in quantity supplied
Inelastic supply means that even large changes in price result in minimal changes in quantity supplied
short run - inelastic
long run - elastic
factors
time period – supply is more elastic in the long run because producers have more time to adjust
availability of resources – if resources are easily available, supply is more elastic
flexibility of production – if a firm can easily switch production (e.g., between goods), supply is more elastic
spare capacity – firms with unused capacity can increase supply quickly, making it more elastic
storage ability – goods that can be stored (like canned food) have more elastic supply
mobility of factors of production – the easier it is to move labor/capital, the more elastic supply becomes
