Economists distinguish between the supply curve of an individual firm and the market supply curve. The market supply curve is obtained by summing the quantities supplied by all suppliers at each potential price. Thus in the graph of the supply curve, individual firms' supply curves are added horizontally to obtain the market supply curve.A demand schedule, depicted graphically as the demand curve, represents the amount of some good that buyers are willing and able to purchase at various prices, assuming all determinants of demand other than the price of the good in question, such as income, tastes and preferences, the price of substitute goods, and the price of complementary goods, remain the same. There may be rare examples of goods that have upward-sloping demand curves. When consumers increase the quantity demanded at a given price, it is referred to as an increase in demand.A situation in a market when the price is such that the quantity that consumers wish to demand is correctly balanced by the quantity that firms wish to supply. When technological progress occurs, the supply curve shifts. For example, assume that someone invents a better way of growing wheat so that the cost of growing a given quantity of wheat decreases. This increase in supply causes the equilibrium price to decrease from P1 to P2. The equilibrium quantity increases from Q1 to Q2 as consumers move along the demand curve to the new lower price. As a result of a supply curve shift, the price and the quantity move in opposite directions.The movement of the supply curve in response to a change in a non-price determinant of supply is caused by a change in the y-intercept, the constant term of the supply equation.Keywords: Tamil Kamakathaikal in Tamil Language, Tamil Kamakathaikal, Tamil Kamakathaikal in PDF, Tamil KamaKeli, Tamil Srungara Kathalu, Srungara Kathalu, Kamakeli, Tamil Kama, Kamasuthra, Tamil PDF
