SELLERS' EXPECTATIONS: One of the five supply determinants assumed constant when a supply curve is constructed, and that shift the supply curve when they change. The other four are resource prices, technology, other prices, and number of sellers. If sellers expect the future price will be greater, then they're likely to sell less today, to take advantage of the higher future price. Alternatively, if sellers expect a lower future price, then they're likely to sell more today, hoping to avoid the lower price. A higher future price induces an decrease in supply and a lower future price induces a increase in supply.
