The law of supply and demand combines two fundamental economic principles describing how changes in the price of a resource, commodity, or product affect its supply and demand.
If you've ever wondered how the supply of a product matches demand or how market prices are set, the law of supply and demand holds the answers. Higher prices cause supply to increase while demand drops. Lower prices boost demand while limiting supply. The market-clearing price is one at which supply and demand are balanced.
The Law of Supply and Demand is essential because it helps investors, entrepreneurs, and economists understand and predict market conditions. For example, a company considering a price hike on a product will typically expect demand for it to decline as a result, and will attempt to estimate the price elasticity and substitution effect to determine whether to proceed regardless.
The Study, which began in January 2010, was completed in December 2012. It defined current and future imbalances in water supply and demand in the Colorado River Basin and the adjacent areas of the Basin States that receive Colorado River water for approximately the next 50 years, and developed and analyzed adaptation and mitigation strategies to resolve those imbalances.
The Study characterized current and future water supply and demand imbalances in the Basin and assessed the risks to Basin resources. Resources include water allocations and deliveries consistent with the apportionments under the Law of the River; hydroelectric power generation; recreation; fish, wildlife, and their habitats (including candidate, threatened, and endangered species); water quality including salinity; flow- and water-dependent ecological systems; and flood control.
In any market transaction between a seller and a buyer, the price of the good or service is determined by supply and demand in a market. Supply and demand are in turn determined by technology and the conditions under which people operate. At one extreme, the market could be populated by a large number of virtually identical sellers and buyers (for example, the market for ballpoint pens). At the other extreme, there might be only one seller and one buyer (as would be the case if I want to barter my table for your quilt).
Economists have formulated models to explain various types of markets. The most fundamental is perfect competition, in which there are large numbers of identical suppliers and demanders of the same product, buyer and sellers can find one another at no cost, and no barriers prevent new suppliers from entering the market. In perfect competition, no one has the ability to affect prices. Both sides take the market price as a given, and the market-clearing price is the one at which there is neither excess supply nor excess demand. Suppliers will keep producing as long as they can sell the good for a price that exceeds their cost of making one more (the marginal cost of production). Buyers will go on purchasing as long as the satisfaction they derive from consuming is greater than the price they pay (the marginal utility of consumption). If prices rise, additional suppliers will be enticed to enter the market. Supply will increase until a market-clearing price is reached again. If prices fall, suppliers who are unable to cover their costs will drop out.
Economists generally lump together the quantities suppliers are willing to produce at each price into an equation called the supply curve. The higher the price, the more suppliers are likely to produce. Conversely, buyers tend to purchase more of a product the lower its price. The equation that spells out the quantities consumers are willing to buy at each price is called the demand curve.
Prices can change for many reasons (technology, consumer preference, weather conditions). The relationship between the supply and demand for a good (or service) and changes in price is called elasticity. Goods that are inelastic are relatively insensitive to changes in price, whereas elastic goods are very responsive to price. A classic example of an inelastic good (at least in the short term) is energy. Consumers require energy to get to and from work and to heat their houses. It may be difficult or impossible in the short term for them to buy cars or houses that are more energy efficient. On the other hand, demand for many goods is very sensitive to price. Think steak. If the price of steak rises, consumers may quickly buy a cheaper cut of beef or switch to another meat. Steak is an elastic good.
