An inelastic supplier (one with a steeper supply curve) will always supply the same amount of goods, regardless of the price, and an elastic supplier (one with a flatter supply curve) will change quantity supplied in response to changes in price.

A change in the price of a commodity affects its demand. Apart from the price, there are several other factors that influence the elasticity of demand. Characteristics of Supply and Demand and Elasticity There are a number of characteristics that affect the elasticity of supply. 2007 Econs … %%EOF PRICE ELASTICITY OF DEMAND Definition The percentage change in quantity demanded to a one percent change in price e.g. Demand and Supply CSE 2010 (2) Assignment 1.

EC101 DD & EE / Manove Elasticity of Demand>Who Cares? The same logarith-mic evolution model would also be displayed by market supply if it For high-income groups, the demand is said to be less elastic as the rise or fall in the price will not have much effect on the demand for a product. We can find the elasticity of demand, or the degree of responsiveness of demand by comparing the percentage price changes with the quantities demanded. increase. *:JZjz���������� �� ?

Demand is elastic. PES > 1), then producers can increase output without a rise in cost or a time delay; If supply is inelastic (i.e. Print. This is an important concept - the elasticity of demand for a good changes as you evaluate it … Let us look at the concept of elasticity of demand and take a quick look at its various types. Let us understand the estimation of elasticity of supply on the demand curve using the point method. 0000001245 00000 n Demand elasticity is the sensitivity of the demand for a good or service due to a change in another factor.

But by how much will the quantity demanded fall? 0000002254 00000 n Thus, the elasticity of supply at point P is calculated as: Point Elasticity of Supply. This tangent intersects X-axis at point T. Another vertical line from P is intersecting X-axis at point B. Besides that, elasticity of demand lets us know what number of additional units of an item will be sold when the value is cut (or what number of fewer units will be sold when the value is increased). Sessions 7 & 8. Determinants of Elasticity of Demand. If a 10% in P leads to a 20% Qd = % change in Qd =-20% =-2 % change in P +10%. <]>> 0000003911 00000 n 1 INTRODUCTION. Classical economics has been unable to simplify the explanation of the dynamics involved. At $3 a cup, the quantity demanded is 15 cups an hour. These are: Consumer Income: The income of the consumer also affects the elasticity of demand. 0000000904 00000 n ! 5.1 THE PRICE ELASTICITY OF DEMAND Figure 5.4(b) shows total revenue and elastic demand. ���� Adobe d� �� C Time – the longer the period of time, the more price elastic is the demand for a product. income elasticity of demand price elasticity of supply 2. 1 1 upvote, Mark this document as useful 1 1 downvote, Mark this document as not useful Embed. This report describes concepts related to transport demand, investigates the influence that factors such as prices and service quality have on travel activity, and how these impacts can be measured using elasticity values. p 3 So far we’ve seen that… On the demand curve, when the price rises, the quantity demanded falls. CHAPTER 6 Lesson 6: Elasticity of Demand and Supply Introduction: Modern market economies rely mainly on the activities of consumers, business, and resource suppliers to allocate resources efficiently. There is no commodity in the market which has perfectly elastic demand. Search inside document . The coefficient is expressed as S by putting a minus sign in front of the equation, thus: E D = – Elasticity of Demand and Supply # 8. 3 Defining and Measuring Elasticity The price elasticity of demand is the ratio of the percent change in the quantity demanded to the percent change in the price as we move along the demand curve. H�=�M 2 2 Elastic demand • Demand is ELASTIC – when the price elasticity (ignoring the negative sign) is greater than -1 – i.e. ELASTICITY OF DEMAND We can study the elasticity of demand under the following categories. Total revenue is $45 an hour. Perfectly Inelastic Demand:- When the demand for a commodity shows no response at all to change in price, whatever is the change in price. The elasticity of demand changes as one moves along the demand curve. +'B�%Qidٯ�X�~���� �ʯ@a��:}��0y�r�����Md�S�q�u� h$�B{i�/�!��i>e��j�>�!��9�^�›�d8�j%. As we saw with demand, the elasticity of supply tends to vary along its curve. Economists measure demand elasticity to … %PDF-1.4 %���� Price elasticity of demand (or elasticity), is the degree to which the effective desire for something changes as its price changes.In general, people desire things less as those things become more expensive. On the supply side, CNS is price inelastic in supply (PES), but more responsive to own price changesthan sawtimber quantity supplied. 10 0 obj << /Length 11 0 R /Filter /FlateDecode >> stream 50 0 obj<>stream 0000002509 00000 n Courses. Those activities and their outcomes are the subject of microeconomics, to which we now turn. PDF | This presentation is on elasticity of demand and supply. Elasticity of Demand and Supply # 7.

In Chapter 2, we learnt that a fall in price will lead to an increase in quantity demanded and vice versa. �&����,h2��V9u˥�ĕ*�(�pe)ݿ\��J��1Ty�]���ОA�y�,g��B��ʢ���ǀO�� �������q��P�k��R˼(�>��>4o�/���e\T_� ͽZ�`A�q��{T�~>*X��.��li�Ґ妐e��ς�����Ҿ�M*�B[%5�$Q�q,��� �� ��.
