JAMB - Economics (2013 - No. 13)
One of the major factors that brings about changes in supply is
market discrimination
availability of storage facilities
the cost of storage
incentives granted to workers
Forklaring
The available of facilities to store produced goods would affect the quantity of goods supplied to the market. Producers maybe willing to produce, but if there are no storage facilities to store the manufactured goods pending when the demand for it will arise, producers would cut down on production thereby affecting the quantity of goods supplied.
