Supply curves have ''elasticities''. just as demand curves do. The major factors effecting
the response of firms to changes in price are expectations of future prices and
time.

The arc elasticity of supply refers to the relationship between changes in price and
the subsequent change in quantity supplied.

Qo is the initial quantity supplied.
Q1 is the new quantity supplied.
Po is the initial price.
P1 is the new price.

Firms will increase production if they believe market prices for the good or service they
produce will increase in the future, and if they believe such a price rise will be a
permanent change in the market. (There is no incentive to increase production and stocks, if
prices are expected to fall again in the near future).
