Supply, demand, and elasticity can be one of the most fundamental elements in economics which linked by marketing acts. Begg 43 states that demand is the amount of goods or services the buyers are willing to buy at an acceptable price. And the supply is the amount of goods or services the producers are willing to sell at an acceptable price.

The main purpose of this essay is firstly explaining what is supply, demand and elasticity and how they influence the market.

Establish the…. Demand and Supply Analysis 1. Demand indicates how much of a good consumers are willing and able to buy at each possible price during a given time period, other things constant.

Demand: effective desire 4. Demand is that desire which backed by willingness and ability to buy a particular commodity…. The law of demand states that, if all other factors remain equal, the higher the price of a good, the less people will demand that good. In other words, the higher the price, the lower the quantity demanded. The amount of a good that buyers purchase at a higher price is less because as the price of a good goes up, so does the opportunity cost of buying that good.

As a result, people will naturally avoid buying a product that will force them to forgo the consumption of something else they value more. The brief meaning is when the price of a product is increased then less will be demanded. Also is the same for the opposite, when the price of a product is decreased then more will be demanded. Like the law of demand, the law of supply demonstrates the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied.

Producers supply more at a higher price because selling a higher quantity at a higher price increases revenue. As more or fewer producers enter the market this has a direct effect on the amount of a product that producers are willing and able to sell. Large Number of Small Firms Each firm produces only a small percentage compared to the overall size of the market output.

If one firm decides to double its output or stop producing entirely, the market is unaffected. The price does not change and there is no discernible change in the quantity exchanged. The meaning is firms has no control over the market price. The stringency of the simplifying assumptions inherent in this approach makes the model considerably more tractable, but may produce results which, while seemingly precise, do not effectively model real world economic phenomena. Partial equilibrium analysis examines the effects of policy action in creating equilibrium only in that particular sector or market which is directly affected, ignoring its effect in any other market or industry assuming that they being small will have little impact if any.

The model is commonly applied to wages , in the market for labor. The typical roles of supplier and demander are reversed. The suppliers are individuals, who try to sell their labor for the highest price. The demanders of labor are businesses, which try to buy the type of labor they need at the lowest price.

The equilibrium price for a certain type of labor is the wage rate. In both classical and Keynesian economics, the money market is analyzed as a supply-and-demand system with interest rates being the price. The money supply may be a vertical supply curve, if the central bank of a country chooses to use monetary policy to fix its value regardless of the interest rate; in this case the money supply is totally inelastic.

Supply and demand

On the other hand, [8] the money supply curve is a horizontal line if the central bank is targeting a fixed interest rate and ignoring the value of the money supply; in this case the money supply curve is perfectly elastic. The demand for money intersects with the money supply to determine the interest rate. Demand and supply relations in a market can be statistically estimated from price, quantity, and other data with sufficient information in the model. This can be done with simultaneous-equation methods of estimation in econometrics.

Such methods allow solving for the model-relevant "structural coefficients," the estimated algebraic counterparts of the theory. The Parameter identification problem is a common issue in "structural estimation. An alternative to "structural estimation" is reduced-form estimation, which regresses each of the endogenous variables on the respective exogenous variables. Demand and supply have also been generalized to explain macroeconomic variables in a market economy , including the quantity of total output and the general price level.

The aggregate demand-aggregate supply model may be the most direct application of supply and demand to macroeconomics, but other macroeconomic models also use supply and demand. Compared to microeconomic uses of demand and supply, different and more controversial theoretical considerations apply to such macroeconomic counterparts as aggregate demand and aggregate supply. Demand and supply are also used in macroeconomic theory to relate money supply and money demand to interest rates , and to relate labor supply and labor demand to wage rates.

The th couplet of Tirukkural , which was composed at least years ago, says that "if people do not consume a product or service, then there will not be anybody to supply that product or service for the sake of price". According to Hamid S. Hosseini, the power of supply and demand was understood to some extent by several early Muslim scholars, such as fourteenth-century Syrian scholar Ibn Taymiyyah , who wrote: "If desire for goods increases while its availability decreases, its price rises.

On the other hand, if availability of the good increases and the desire for it decreases, the price comes down.

Essay Supply and Demand and Price Elasticity

The phrase "supply and demand" was first used by James Denham-Steuart in his Inquiry into the Principles of Political Economy , published in In The Wealth of Nations , Smith generally assumed that the supply price was fixed but that its "merit" value would decrease as its "scarcity" increased, in effect what was later called the law of demand also. Ricardo, in Principles of Political Economy and Taxation , more rigorously laid down the idea of the assumptions that were used to build his ideas of supply and demand.

Antoine Augustin Cournot first developed a mathematical model of supply and demand in his Researches into the Mathematical Principles of Wealth , including diagrams.

During the late 19th century the marginalist school of thought emerged. The key idea was that the price was set by the subjective value of a good at the margin. This was a substantial change from Adam Smith's thoughts on determining the supply price. In his essay "On the Graphical Representation of Supply and Demand", Fleeming Jenkin in the course of "introduc[ing] the diagrammatic method into the English economic literature" published the first drawing of supply and demand curves in English, [15] including comparative statics from a shift of supply or demand and application to the labor market.

Much of the buying and selling are now conducted online using platforms such as Amazon and eBay, where the profiles of the customers are captured and analyzed. Tshilidzi Marwala and Evan Hurwitz in their book [17] observed that the advent of artificial intelligence and related technologies such as flexible manufacturing offers the opportunity for individualized demand and supply curves to be generated.

This has been found to reduce the degree of arbitrage in the market, allow for individualized pricing for the same product and brings fairness and efficiency into the market. The philosopher Hans Albert has argued that the ceteris paribus conditions of the marginalist theory rendered the theory itself an empty tautology and completely closed to experimental testing. Cambridge economist Joan Robinson attacked the theory in similar line, arguing that the concept is circular: "Utility is the quality in commodities that makes individuals want to buy them, and the fact that individuals want to buy commodities shows that they have utility" [19] : 48 Robinson also pointed out that if we take changes in peoples' behavior in relation to a change in prices or a change in the underlying budget constraint, then we can never be sure to what extent the change in behavior was due to the change in price or budget constraint and how much was due to a change in preferences.

Piero Sraffa 's critique focused on the inconsistency except in implausible circumstances of partial equilibrium analysis and the rationale for the upward slope of the supply curve in a market for a produced consumption good. Some economists criticize the conventional supply and demand theory for failing to explain or anticipate asset bubbles that can arise from a positive feedback loop.
