The
Concept Introduction:
Price support system- In the PSS, the government by law determines the minimum price at which the sellers must sell his product in the market, which is higher than the competitive market price. The market price of the higher is kept high to support the sellers being crushed under cut-throat competition.
Law of Supply- The law establishes a direct relationship between price and quantity supplied assuming ceteris paribus or keeping all other variables constant. The supply curve is accordingly an upward sloping curve from left to right keeping the price on the Y-axis and quantity supplied on the X-axis.
Increase/Decrease in demand- Change in demand consequent upon a change in the factors other than price cause the demand to increase or decrease. Change in income, wealth or preferences of the consumers, for example, are factors that lead to a change in the demand among other factors. Prices remaining unchanged, these factors cause the demand curve to shift inward or outward.
Increase/Decrease in Supply- Change in supply consequent upon a change in the factors other than price cause the supply to increase or decrease. Change in technology, cost of the factors of production, factor productivity etc, for example, are factors that lead to a change in the supply among other factors. Prices remaining unchanged, these factors cause the supply curve to shift inward or outward.
