Two factors that govern the supply of commodities:-
1)
Goal of the firm: If goal of the firm is to maximize profits, more
quantity of the commodity will be offered only at higher price. If goal
of the firm is to maximize sales more will be supplied even at the same
price.
2) State of
technology: Improvement in the technique of production reduces cost of
production. Consequently, more of the commodity is supplied at its
existing price.
