	Supply and demand - Wikipedia, the free encyclopedia
		The theory of supply and demand is important for some economic schools' understanding of a market economy in that it is an explanation of the mechanism by which many resource allocation decisions are made.
		Graphically the situation can be represented by two curves: one showing the price-quantity combinations buyers will pay for, or the demand curve; and one showing the combinations sellers will sell for, or the supply curve.
		Even with downward-sloping demand curves, it is possible that an increase in income may lead to a decrease in demand for a particular good, probably due to the existence of more attractive alternatives which become affordable: a good with this property is known as an inferior good.

		The theory of supply and demand is important in the functioning of a market economy in that it explains the mechanism by which many resource allocation decisions are made.
		The shape of the curves far away from the equilibrium point are less likely to be important because they do not effect the market clearing price and will not effect it unless large shifts in the supply or demand occur.
		Finally, most of the basics of the modern theory of supply and demand was finalized by Alfred Marshall and Léon Walras when they combined the ideas about supply and the ideas about demand and began looking at the equilbrium point where the two curves crossed.

	Demand Curve for Output
		The demand curve for output is a constraint on the firm because it gives the maximum price that a firm can charge for each level of production.
		From the viewpoint of the firm, it is not the demand curve, but the child of the demand curve, the marginal revenue curve, which is of vital importance.
		The demand curve for this farmer is flat at $4.00, and so is his marginal revenue curve.

	Demand Curve
		The law of demand states that quantity demanded moves in the opposite direction of price (all other things held constant), and this effect is observed in the downward slope of the demand curve.
		For basic analysis, the demand curve often is approximated as a straight line.
		When there is a change in an influencing factor other than price, there may be a shift in the demand curve to the left or to the right, as the quantity demanded increases or decreases at a given price.

	Thesis on Demand Curve
		Demand is "the quantity of a commodity that will be required at any given price over some given period of time".
		A demand curve is a graphical representation of the data in table with values of demand called a demand schedule.
		A second example of exceptional demand curves are presented by goods which have a elitist appeal.

	AllRefer.com - supply and demand (Economics: Terms And Concepts) - Encyclopedia
		supply and demand, in classical economics, factors that are said to determine price, by correlating the amount of a given commodity producers hope to sell at a certain price (supply), and the amount of that commodity that consumers are willing to purchase (demand).
		Demand refers to the quantity of a good that is demanded by consumers at any given price.
		In a perfectly competitive economy, the combination of the upward-sloping supply curve and the downward-sloping demand curve yields a supply and demand schedule that, at the intersection of the two curves, reveals the equilibrium price of an item.

		Short-run equilibrium: When the short-run aggregate supply curve intersects the aggregate demand curve, the economy is at a short-run equilibrium price and output level.

	A Demand Curve (Site not responding. Last check: 2007-10-09)
		In the first case, there is a shift of the curve and in the second, there is a movement along it.
		That’s why the first is sometimes called a change in demand and the second is sometimes called a change in the quantity demanded.
		Or to put it more exactly, the supply curve of the firm is the same thing as the marginal cost of the firm since the supply curve of the firm links price to quantity supplied and Price= Marginal Cost.

	SparkNotes: Elasticity: Elasticity
		If the elasticity of demand is greater than or equal to 1, meaning that the percent change in quantity is great than the percent change in price, then the curve will be relatively flat and elastic: small price changes will have large effects on demand.
		If the elasticity of the demand curve is less than 1, meaning the percent change in quantity is less then the percent change in price, then the curve will be steep and inelastic: it will take a big change in price to affect demand.
		Except for curves with an elasticity of 1, elasticity on straight-line curves is not constant.

	Elasticity, Total Revenue, and Linear Demand
		The first demand equation beginning economics students usually see is that of a linear, or straight-line demand curve.
		According to tradition, when economists draw a demand curve in a two dimensional diagram, they put the price on the vertical axis, and the quantity on the horizontal axis, like the diagram in the upper right corner of the applet.
		This is because the applet adjusts the scale of each axis based on where the demand curve crosses it.

	Inflation and the Phillips Curve
		The Phillips Curve was an empirical phenomenon looking for a theory and, around that time, there were two competing theories of inflation, both of which were expressed by Keynes in various places: "demand-pull" inflation and "cost-push" inflation - terms, as Machlup (1960) has shown, that can have a far from obvious meaning.
		The non-linearity of the Phillips Curve is justified by appeals to frictional unemployment and institutional difficulties at the extremes.
		Thus, the migration of the so-called "short-run" Phillips Curve (as in the move in Figure 14) was explained in terms of ever-higher inflationary expectations.

	Demand Curve Shifts
		When price changes and other demand determinants are constant, the outcome is given by an equilibruim on the same demand curve D1 (for example, imagine the supply curve shifting and demand curve constant).
		We call this change on one curve a "change in quantity demanded." If a non-price determinant changes in such a way as to increase demand, this is a "shift in" or just "change in" the demand curve such as from D1 to D2.
		At this point, either tackle the supply curve or go to the self-quiz and practice your understanding of demand concepts on the first two questions (other questions might involve supply analysis also.) The self-quiz requires a browser that can handle frames.

	Demand Curve Analysis
		For the total market demand (rather than Bob's individual one) the number of buyers in the market is also a determinant of the amount purchased.
		The DEMAND CURVE is defined as the relationship between the price of the good and the amount or quantity the consumer is willing and able to purchase in a specified time period, given constant levels of the other determinants--tastes, income, prices of related goods, expectations, and number of buyers.
		As the price P on vertical axis is lowered from $75 to $50, the quantity demanded Q is increased from two pairs to three pairs of blue jeans.
