Supply, demand, and market equilibrium | Microeconomics | Khan Academy
Jan 14, economics textbooks show the dependence of supply and demand on price, but do .. The source for this relation is the supply curve provided. A demand curve or a supply curve is a relationship between two, and only two, . In other words, when income increases, the demand curve shifts to the left. To understand the relationship between supply and demand, there are certain things In other words, the higher the price, the lower the quantity demanded.
If buyers wish to purchase more of a good than is available at the prevailing price, they will tend to bid the price up. If they wish to purchase less than is available at the prevailing price, suppliers will bid prices down.
Thus, there is a tendency to move toward the equilibrium price. That tendency is known as the market mechanism, and the resulting balance between supply and demand is called a market equilibrium. As the price rises, the quantity offered usually increases, and the willingness of consumers to buy a good normally declines, but those changes are not necessarily proportional. The measure of the responsiveness of supply and demand to changes in price is called the price elasticity of supply or demand, calculated as the ratio of the percentage change in quantity supplied or demanded to the percentage change in price.
Economic Basics: Supply And Demand
Thus, if the price of a commodity decreases by 10 percent and sales of the commodity consequently increase by 20 percent, then the price elasticity of demand for that commodity is said to be 2. The demand for products that have readily available substitutes is likely to be elastic, which means that it will be more responsive to changes in the price of the product.
That is because consumers can easily replace the good with another if its price rises. Firms faced with relatively inelastic demands for their products may increase their total revenue by raising prices; those facing elastic demands cannot.
Supply-and-demand analysis may be applied to markets for final goods and services or to markets for labour, capitaland other factors of production. It can be applied at the level of the firm or the industry or at the aggregate level for the entire economy.Market equilibrium - Supply, demand, and market equilibrium - Microeconomics - Khan Academy
LPG gas, Petrol, etc. Prices of such commodities increases, demand does not show any tendency to contract and it negatives the law. If consumers measure the desired ability of the utility of a commodity, solely by its price and nothing else, then they tend to buy more of the commodity at higher price and less of it at lower price.
Gold ornaments, Diamonds, hair paintings. Higher the price of the good, greater will be the prestige of the buyer in the society and vice-versa. When price falls, the commodity comes within the reach of lower class people and they tend to demand more because of demonstration effect.
If people expect the price of good to rise in near future, they demand more even at higher price. And if they expect the price to fall in near future, they demand less of it even at lower price.

Thus more quantity of goods is demanded at rising prices and less quantity of goods is demanded at falling prices. This seems contrary to law of demand. These are special type of inferior goods named after Sir Robert Giffen. So there is direct relationship between price and demand. People increase preferences towards superior goods due to rise in their real income. This tendency is found in low class people. However if price increases beyond certain limit, naturally demand may fall as people prefer superior goods.
