Price is what the producer receives for selling one unit of a good or service. A rise in price almost always leads to an increase in the quantity supplied of that good or service, while a fall in price will decrease the quantity supplied. When the price of gasoline rises, for example, it encourages profit-seeking firms to take several actions: expand exploration for oil reserves; drill for more oil; invest in more pipelines and oil tankers to bring the oil to plants, where it can be refined into gasoline; build new oil refineries; purchase additional pipelines and trucks to ship the gasoline to gas stations; and open more gas stations or keep existing gas stations open longer hours.\r\n\r\nEconomists call this positive relationship between price and quantity supplied\u2014that a higher price leads to a higher quantity supplied, and a lower price leads to a lower quantity supplied\u2014the <strong>law of supply<\/strong>.\u00a0The law of supply, like the law of demand, assumes that all other variables that affect supply are held equal (<em>ceteris paribus<\/em>).\r\n<div class=\"textbox exercises\">\r\n<h3><strong>Supply vs. Quantity Supplied<\/strong><\/h3>\r\nIn economic terminology, supply is not the same as quantity supplied. When economists refer to supply, they mean the relationship between a range of prices and the quantities supplied at those prices, a relationship that can be illustrated with a supply curve or a supply schedule. When economists refer to <strong>quantity supplied<\/strong>, they mean only a certain point on the supply curve, or one quantity on the supply schedule. In short, supply refers to the curve, and quantity supplied refers to the (specific) point on the curve.\r\n\r\n<\/div>\r\nFigure 1, below, illustrates the law of supply, again using the market for gasoline as an example. Like demand, supply can be illustrated using a table or a graph. A\u00a0<strong>supply schedule<\/strong> is a table\u2014like Table 1, below\u2014that shows the quantity supplied at a range of different prices. Again, price is measured in dollars per gallon of gasoline, and quantity demanded is measured in millions of gallons. A <strong>supply curve<\/strong>\u00a0is a graphic illustration of the relationship between price, shown on the vertical axis, and quantity, shown on the horizontal axis. You can see from this curve (Figure 1) that as the\u00a0price rises, quantity supplied also increases, and vice versa. The supply schedule and the supply curve are just two different ways of showing the same information. Notice that the horizontal and vertical axes on the graph for the supply curve are the same as for the demand curve.\r\n\r\n[caption id=\"attachment_13568\" align=\"alignnone\" width=\"1024\"]<img class=\"wp-image-13568 size-large\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images\/wp-content\/uploads\/sites\/3006\/2016\/07\/10000000\/CNX_Econ_C03_00211-1024x585.jpg\" alt=\"The graph shows an upward-sloping supply curve that represents the law of supply.

Nearly all supply curves, however, share a basic similarity: they slope up from left to right and illustrate the law of supply. As the price rises, say, from $1.00 per gallon to $2.20 per gallon, the quantity supplied increases from 500 gallons to 720 gallons. Conversely, as the price falls, the quantity supplied decreases.\r\n<div class=\"textbox tryit\">\r\n<h3>Practice Questions<\/h3>\r\nhttps:\/\/assess.lumenlearning.com\/practice\/c9b33a23-8b8f-406e-8d78-3aff4d0779b5\r\n\r\nhttps:\/\/assess.lumenlearning.com\/practice\/ee801d12-8128-4595-ab61-91496270ff55\r\n\r\n<\/div>\r\n<div class=\"textbox learning-objectives\">\r\n<h3>glossary<\/h3>\r\n[glossary-page][glossary-term]law of supply:\u00a0[\/glossary-term]\r\n[glossary-definition]the common relationship that a higher price leads to a higher quantity supplied of a certain good or service and a lower price leads to a lower quantity supplied, while all other variables are held constant[\/glossary-definition][glossary-term]quantity supplied:\u00a0[\/glossary-term][glossary-definition]the total number of units of a good or service producers are willing to supply at a given price[\/glossary-definition][glossary-term]supply:\u00a0[\/glossary-term][glossary-definition]the relationship between\u00a0the\u00a0price of a certain good or service and\u00a0the quantity of that good or service producers are willing to offer for sale [\/glossary-definition][glossary-term]supply curve:\u00a0[\/glossary-term][glossary-definition]a graphic representation of the relationship between price and quantity supplied of a certain good or service, with price on the vertical axis and quantity on the horizontal axis [\/glossary-definition][glossary-term]supply schedule:\u00a0[\/glossary-term][glossary-definition]a table that shows\u00a0the quantity demanded\u00a0for a certain good or service at\u00a0a range of prices[\/glossary-definition][\/glossary-page]\r\n\r\n<\/div>","rendered":"<div class=\"textbox learning-objectives\">\n<h3>Learning Outcomes<\/h3>\n<ul>\n<li>Explain the law of supply<\/li>\n<li>Explain a supply curve<\/li>\n<\/ul>\n<\/div>\n<div class=\"textbox key-takeaways\">\n<h3>Watch It<\/h3>\n<p>The law of supply states that more of a good will be provided the higher its price; less will be provided the lower its price, <em>ceteris paribus<\/em>.
