(i) State of Technology : State of technology also affects supply of the commodity. Improvement in the technique of production reduces cost of production. Consequently, more of the commodity is supplied at its existing price.

(ii) Price of Factors of Production : Supply of a commodity is also affected by the price of factors used for the production of the commodity. If the factor price decreases, cost of production also reduces. Accordingly, more of the commodity is supplied at its existing price. Conversely, if the factor price increases cost of production also increases. In such a situation less of the commodity is supplied at its existing price.

(iii) Goals of the Firm : If goal of the firm is to maximise profits, more quantity of the commodity will be offered at a higher price. On the other hand, if goal of the firm is to maximise sales (or maximise output or employment) more will be supplied even at the same price.

(iv) Future Price Expectations : If the producer expects price of the commodity to rise in the near future, current supply of the commodity will reduce. If, on the other hand, fall in the price is expected, current supply will increase.
