Download file to see previous pages There are two main reasons why we use percentages instead of absolute amounts. They are;
• If absolute changes are used, the choice of units will be arbitrary affect the impression of the consumers’ responsiveness. (Lipsey R.G and Christal K.A2007pp66) For example, if the price of cereals changes from \$10 to \$9 and the quantity demanded changed from 60 to 100 packets. The coefficient of price elasticity of demand will be 40. It will be seen that consumers are very sensitive to price change and the demand will be elastic.  But if the monetary units are changed from dollars to pennies we see that change of 100 pennies causes a change of 40 packets of cereals.  This will falsely make people believe that demand is inelastic. To eliminate this problem percentage changes are used. (Lipsey R.G and Christal K.A2007pp66)
• By using percentage, consumers’ responsiveness to price changes of different products can be easily compared. For example, if two products are taken i.e. cereals and computers. It is easier to compare the effects on quantity demanded of \$1 increase in the price of a \$300 computer and \$1 dollar increase in the price of \$1 soft drink.
Various interpretations of price elasticity of demand coefficient
• When Ed>1, the demand is said to be elastic. This occurs when a specific change in price results in a larger percentage change in quantity demanded.(Mankiw N.G,1998p93) Graphically it can be illustrated as follows; ...Download file to see next pagesRead More

### Price Elasticity of Demand

...﻿Price Elasticity of DemandPrice elasticity of demand refers to how sensitive the amount of a good or service that is highly needed respond to change in prices. A good or service with many close substitutes will have its demand being more elastic since the customers can very simply adjust to another good due to increase in price of that good in comparison to other goods in the marketplace. On the contrary, a produce with little or no close substitutes will have inelastic demand since the customers have no other produce to adjust to. Price elasticity of demand (Ed) = percentage in amount demanded Percentage of change in price = Δqd/qd...

### Price Elasticity of Demand

In understanding this given economic issue, we need to study the application of Law of Supply and Demand and price elasti of demand in our product markets. From there we can see how the simple tools of demand and supply can affect the prices of goods, the consumers’ spending behavior and the businesses’ decisions and the operations of the entire economic system. If the demand for corn increases due to its use as an alternative energy source, there will be a decrease in the supply of corn's substitute such as soybean. This is because change in the price of related goods is a determinant of demand (McConnell & Brue, 2002). As corn and soybean are substitutes, one can be used in place of the other, so when the demand for corn is incr...

In this case, Mylan Laboratories has increased their prices by close to 600% and this will have an effect on the demand as many people cannot afford the extra expense that is accompanied by the price increment. There are a number of factors that will inform the elasticity of the demand. First, the availability of substitutes is a major determinant (Wall & Griffiths 2008). With the presence of generic drugs that are supplied by competitors, the increase in prices of the patented Mylan Laboratories’ drugs...

### Price Elasticity of Demand

...﻿ One of the major concepts of microeconomics is price elasticity of demand, which refers to sensitivity levels of demand for a given product or service to changes in its price. Elasticity of demand co-efficiency is the percentage change in the quantity of a product or frequency of a service in reference to percentage variation in price. Changes in price levels and quantity conversely relate to each other, with the obvious implication of a decrease in product demand with increase in its price. Demand on the other hand refers to the amount of a commodity that buyers are willing and capable of buying at a given price level. Many factors determine price elasticity of demand in a free market economy. Firstly, the product uniqueness...

### Demand and Price Elasticity of Demand

...? Demand and price elasti of demand Part A. According to the article, a drop in the price for Bordeaux wine could increase the sales. This strategy is explained by the price concept of demand elasticity. Whenever a firm comes up with a pricing strategy it needs to analyze all the outside factors which affect the firm’s decisions. These factors may include the consumers, and the market competition among other factors. Considering the price strategy that is demand based, the market would always set out a price for a commodity after researching the desires of consumers and verifying the price range which is acceptable to the market target. In the case of Bordeaux, the consumers had proposed a low wine price. This implies that reducing...

### Price Elasticity of Demand

...) / [(Q1 + Q2) / 2]           % Change in Price = (P2 - P1) / [(P1 + P2) / 2] where,         Q1 = Initial quantity         Q2 = Final quantity         P1 = Initial price         P2 = Final price Now let us consider the different range of values of price elasticity of demand. Elasticity = 1 When elasticity is equal to one it is called unit elasticity and the change in quantity demanded causes a proportionate change in price. So a price change in either direction will not yield a change in revenue. Elasticity > 1 When elasticity is greater than 1 the quantity demanded changes to a greater degree than the change in price. The demand curve aligns increasingly aligns itself to the x- axis in the case of near infinite elasticity, meaning than...

### Price Elasticity of Demand

﻿Price Elasticity of Demand
Effect of Increase in Demand on Supply of Substitute Good
If corn is discovered as an alternative source of energy, its demand increases prompting a scarcity of corn. The buyers will compete for the scarce corn thereby pushing the price of corn up. This acts as an incentive for farmers to produce more corn and sell at high price as the law of supply states that price of a good is directly related to its supply; if price increases, quantity supplied increases (Tucker, 2009). However, the supply of corn also depends on availability of resources or inputs such as land and labor, prices of substitutes, and number of farmers. If more farmers decide to produce corn, the demand will be met. The price o...

### A Stable Demand for Money Function is Necessary for the Success of Monetarism

... as exogenous. As a rule, the causation will run from left (MV) to right (PT). The increase in money supply will result to an exact proportionate increase in the Price Level (P) since Velocity (V) and Level of Transactions (T) are fixed and money supply (M) is exogenous. Therefore, we can conclude that a sudden increase in the money supply can result to price inflation. This is the main reason why a stable demand for money function is important. Because when M increases given that T and V are fixed; therefore, Money (M) and Price (P) will be greater than the Level of Transaction (T) and Velocity (V). Let us look at the situation wherein the supply of money is more than the demand for money. (See Figure 1 on page 5) The purchasing...

### Impact of Forecasting Demand in Food and Beverage Service Organisation

Purchasing, storage, and production scheduling are some of the basic things needed to be adjusted periodically based on the demand in the market. It is not wise to purchase too many materials at a time when the demand was less. The to and fro movement of the material is essential for the smooth functioning of the storage area. Goods purchased and stored in the store must be despatched to the production area periodically before the expiry date to ensure that the organization might not suffer. But if the demand was poor, it is not possible to ensure the despatch of goods to the production unit which will result in wastage of materials. Generally, Purchasing, Storage and Production are the three areas in any manufacturing unit which...

### Why Price of Laptop Computers Fell

The price at this equilibrium was P0 and the Number of Laptops was Q0.
As the demand fell due to the reasons discussed below, the demand curve shifted to left, D1. If the prices were to stay at P0, the quantity demanded, Qx would have been much lower than quantity supplied, Q0. In order to increase consumer demand, firms would have to reduce the laptop prices until it reaches the new equilibrium level, P1. At this point, the market is in equilibrium. The reduction in price increases the demand and the new quantity of laptops in the market would be Q1.
The most basic thing to consider in determining the price of a laptop is the technology used in it (Neidalos, 2010). Technology advances at a very rapid pace in today&rsquo...

### 1.Describe how equilibrium occurs using the aggregate supply (AS) and aggregate demand (AD) framework. Use this framework to explain why real GDP fluctuates around potential GDP with specific reference to the current state of the UK economy

Aggregate demand curve represents the desired spending, consumer behaviour and the buying of equipment by governments and foreigners. The aggregate demand rises with the increase in expenditure caused by increased optimism by the households on lifetime incomes and increased need for the product. The combined monetary assets and the decrease in interest rates stimulate the desire to spend by the firms and households. Low interest rates reduce the saving reward and borrowing costs for households, but for businesses, this reduces the borrowing costs for investing in equipment and plant (James, Walte and James 2006, p. 777-790).
The aggregate demand curve slopes downwards due to the fixed nominal value for some assets, particularl...

... increased significantly and 1986 when energy prices decreased significantly. Research findings indicate that while energy prices corresponded with consumer spending, it was not the primary determining factor (Edelstein & Killan, 2009). Verboven (2002) examined empirical data of automobile purchasing in Europe where consumers can choose between diesel and gasoline vehicles. Diesel vehicles get better mileage on the diesel and diesel attracts less tax than gasoline. Yet, consumers in Europe are more partial to gasoline vehicles (Verboven, 2002). Moreover, despite the perceived high demand for fuel efficient cars such as hybrid cars, annual sales did not meet expectations (Read, 2012; Tuttle, 2012). It would therefore appear...
