Supply curve

The quantity of a commodity that is supplied in the market depends not only on the price obtainable for the commodity but also on potentially many other factors, such as the prices of substitute products, the production giải pháp công nghệ, và the availability và cost of labour & other factors of production. In basic economic analysis, analyzing supply involves looking at the relationship between various prices & the quantity potentially offered by producers at each price, again holding constant all other factors that could influence the price. Those price-quantity combinations may be plotted on a curve sầu, known as a supply curve sầu, with price represented on the vertical axis & quantity represented on the horizontal axis. A supply curve is usually upward-sloping, reflecting the willingness of producers to sell more of the commodity they produce in a market with higher prices. Any change in non-price factors would cause a shift in the supply curve sầu, whereas changes in the price of the commodity can be traced along a fixed supply curve sầu.

As the price rises, the quantity offered usually increases, & the willingness of consumers to buy a good normally declines, but those changes are not necessarily proportional. The measure of the responsiveness of supply và dem& to lớn changes in price is called the price elastithành phố of supply or demand, calculated as the ratio of the percentage change in quantity supplied or demanded to the percentage change in price. Thus, if the price of a commodity decreases by 10 percent & sales of the commodity consequently increase by đôi mươi percent, then the price elasticity of demvà for that commodity is said to be 2.

The dem& for products that have readily available substitutes is likely khổng lồ be elastic, which means that it will be more responsive sầu to changes in the price of the product. That is because consumers can easily replace the good with another if its price rises. The demand for a sản phẩm may be inelastic if there are no cđại bại substitutes và if expenditures on the hàng hóa constitute only a small part of the consumer’s income. 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 lớn markets for final goods and services or to lớn markets for labour, capital, & other factors of production. It can be applied at the màn chơi of the firm or the industry or at the aggregate cấp độ for the entire economy.
