Econ: Demand

1 demand-wordcloud
In a market economy, buyers and sellers set prices. Demand is the amount of something that consumers are willing and able to buy at various prices. Demand does not always stay the same and can be determined by a demand schedule, which shows the various quantities demanded of a particular product at all prices that might prevail in the market at a given time.

The Law of Demand states that people will buy more of a product at a lower price than they will buy at a higher price, if nothing else changes. Real income, possible substitutes, and diminishing marginal utility help explain the inverse relationship between price and quantity demanded. Demand does not always stay the same.

A demand curve is the graph that shows the relationship between the price of an item and the quantity demanded. A change in the quantity demanded is a result of a change in price.

There are a number of factors that will cause demand to either increase or decrease. These factors, TOESIS, are called the determinants of demand: changes in Tastes and preferences, Other related goods: complementary goods, consumer Expectation, changes in Size of population, changes in Income, and Substitute goods. A change in demand for a particular item shifts the entire demand curve to the left or right.

A demand curve shows all the prices and quantities at which consumers are willing and able to purchase a good or service. The law of demand states that consumers will want to buy more at a lower price and less at a higher price.

There is a difference between a change in demand and a change in quantity demanded.

A change in quantity demanded is a movement along the demand curve and can be caused only by a change in the price of the good or service. At a lower price, a larger quantity is demanded. A change in demand is a shift in the curve whereby more or less is demanded at every price. Changes in preferences incomes, expectations, population, or the prices of complementary or substitute goods will cause a change in demand.
