This assignment explains how fuel monetary value will consequence on auto supply after the war breaks out in a state. Its comprises of the debut of the fuel and auto market equilibrium with the assistance of graph, the treatment of the revenue enhancements imposed due to the snap of demand, and decision at the terminal of study.

We are looking for the equilibrium monetary value and equilibrium measure. The equilibrium monetary value is the monetary value where the ends of purchaser and marketer lucifer. In other words, Market equilibrium is a status where the sums of goods or services which are demanded by purchasers are equal to the sum of goods or services supplied by Sellerss ( McConnell, Brue & A ; Flynn, 2009 ) .

However, alteration in purposes of demand, such as monetary value of merchandise, the family ‘s income, and client ‘s penchant will impact the equilibrium of a market. On the other side, alterations in the determiner of provider such as alterations in production costs, engineering and monetary values of related goods and services cause the alteration in equilibrium markets ( McConnell, Brue & A ; Flynn, 2009 ) .

For case any rise in fuel monetary value will increase the entire cost of utilizing car/vehicles. However paying more for fuel for utilizing a auto is unpredictable. Consumers try to set their auto ‘s use cost by exchanging to fuel efficiency autos. As a consequence, alteration in fuel monetary value in fact alters consumer demands and trials in auto.


Equilibrium means aA place of equality or a balance between market demand and supply. Without a displacement in demand and/or supply there will be no alteration in market monetary value.

Figure 1: Market Equilibrium point

In the diagram above, the measure demanded and supplied at monetary value P1 are equal. At any monetary value above P1, supply exceeds demand and at a monetary value below P1, demand exceeds supply. In other words, monetary values where demand and supply are out of balance are look of disequilibrium. Changes in the conditions of demand or supply will switch the demand or provide curves.A This will do alterations in the equilibrium monetary value and measure in the market.

2.1 Changes in Market Demand and Equilibrium Price

Figure 2: Change in Equilibrium Point for Market Demand

The demand curve may switch to the right ( addition ) for several grounds:

A rise in the monetary value of a replacement or a autumn in the monetary value of a complement

An addition in consumers ‘ income or their wealth

Changing consumer gustatory sensations and penchants in favour of the merchandise

A autumn in involvement rates ( i.e. borrowing rates on bank loans or mortgage involvement rates )

A general rise in consumer assurance and optimism

The outward displacement in the demand curve causes a motion ( enlargement ) along the supply curve and a rise in the equilibrium monetary value and quantity.A Firms in the market will sell more at a higher monetary value and hence have more in entire gross. The contrary effects will happen when there is an inward displacement of demand. A displacement in the demand curve does non do a displacement in the supply curve. Demand and supply factors are assumed to be independent of each other although some economic experts claim this premise is no longer valid.

2.2 Changes in Market Supply and Equilibrium Price

Figure 3: Change in Equilibrium Point for Market Supply

The supply curve may switch outwards if there is:

A autumn in the costs of production ( e.g. a autumn in labour or natural stuff costs )

A authorities subsidy to manufacturers that reduces their costs for each unit supplied

Favorable climatic conditions doing higher than expected outputs for agricultural trade goods

A autumn in the monetary value of a replacement in production

An betterment in production engineering taking to higher productiveness and efficiency in the production procedure and lower costs for concerns

The entry of new providers ( houses ) into the market which leads to an addition in entire market supply available to consumers

The outward displacement of the supply curve increases the supply available in the market at each monetary value and with a given demand curve, there is a autumn in the market equilibrium priceA from P1 to P3 and a rise in the measure of end product bought and sold from Q1 to Q3. The displacement in supply causes an enlargement along the demand curve.


Elasticity refers to the grade of reactivity in supply or demand in relation to alterations in monetary value. If a curve is more elastic, so little alterations in monetary value will do big alterations in measure consumed. If a curve is less elastic, so it will take big alterations in monetary value to consequence a alteration in measure consumed.

Price snap of demand ( E ) = % I” in measure demanded ? % I” in monetary value


E = 0: absolutely inelastic

E = 0 a‰¤ 1: inelastic

E = 1: unitary rubber band

E = & gt ; 1: elastic.

E = a?z : absolutely elastic

* Note that although monetary value and measure demanded move in opposite waies, snap will ever be positive by convention.

Diagrammatically, snap can be represented by the visual aspect of the supply or demand curve. A more elastic curve will be horizontal, and a less elastic curve will lean more vertically. When speaking about snap, the term “ level ” refers to curves that are horizontal ; a “ flatter ” elastic curve is closer to absolutely horizontal. Elasticity can be stand foring if measure changes a batch, demand isA elasticA and stretches. Meanwhile, if measure changes merely a small, demand isA inelasticA and the measure does non stretch much.A

Figure 4: Elastic and Inelastic Curves

At the bounds, a absolutely elastic curve will be horizontal, and a absolutely inelastic curve will be perpendicular. Hint: You can utilize absolutely inelastic and absolutely elastic curves to assist you retrieve what inelastic and elastic curves look like: anA inelastic curve is more perpendicular, like the letterA I. An elastic curve is flatter, like the horizontal lines in the letterA E.

Figure 5: Absolutely Elastic and Perfectly Inelastic Curves

Price snap of demand, besides called the snap of demand, refers to the grade of reactivity in demand measure with regard to monetary value. See a instance in the figure below where demand is really elastic, that is, when the curve is about level. You can see that if the monetary value alterations from $ .75 to $ 1, the measure decreases by a batch. There are many possible grounds for this phenomenon. Buyers might be able to easy replace away from the good, so that when the monetary value additions, they have small tolerance for the monetary value alteration. Possibly the purchasers do n’t desire the good that much, so a little alteration in monetary value has a big consequence on their demand for the good.

Many factors influence snap, some of which include:

Necessities versus LuxuriesA – It is harder to happen replacements for necessities so measure demanded will alter less.

Handiness of Close SubstitutesA – If there are close replacements, purchasers will travel off from more expensive points and demand will be elastic.

Definition of the MarketA – The more loosely we define an point, the more possible replacements and the more elastic the demand.

Time HorizonA – The longer the clip available, the easier to happen replacements and the more elastic the demand.

Relative Size of PurchaseA – Purchases which are a really little part of entire outgo tend to be more inelastic, because consumers are non worried about the excess outgo.

3.1 The Effectss of Elasticity on Equilibrium Price and Quantity

As we already know, equilibrium monetary value and equilibrium measure in a given market are determined by the intersection of the supply and demand curves. Depending on the snap of supply and demand, the equilibrium monetary value and measure can act otherwise with displacements in supply and demand. We can see one illustration of how this works if we imagine a supply curve switching in and out along a individual demand curve.

Figure 6: Shifts in Supply with Elastic Demand

If demand is really elastic, so displacements in the supply curve will ensue in big alterations in measure demanded and little alterations in monetary value at the equilibrium point.

Figure 7: Shifts in Supply with Inelastic Demand

If demand is really inelastic, nevertheless, so displacements in the supply curve will ensue in big alterations in monetary value and little alterations in measure at the equilibrium point.


There is a large impact on the fuel and auto status during the war breaks out because autos are lasting goods, possible clients must see in doing a determination harmonizing to the initial cost of geting a auto, they are besides ongoing costs of runing the auto. An addition in the monetary value of fuel will therefore increase the usage cost for all ( fuel-powered ) auto. Precisely how much the cost-per-mile additions for a peculiar theoretical account, nevertheless, depends on the features of the theoretical account ; the larger and heavier a vehicle, and the greater its HP, the greater consequence a given fuel monetary value addition will hold on its cost of use. If there were sufficiently attractive replacements for autos as a whole, we might anticipate all-embracing additions in use costs to diminish demand for all auto theoretical accounts. If this is the instance, the demand for autos in general will be comparatively inelastic to alterations in fuel monetary values, taking to lessenings in the demand for some vehicles. Specifically, in both new and used auto markets, we would anticipate to see demand addition for fuel-efficient autos and lessening for fuel-inefficient autos when fuel monetary values addition.

While we might anticipate fuel monetary values to hold a similar in both new and used markets on the demand for autos of different fuel efficiencies, a alteration in fuel monetary values could however take to really different equilibrium results in the two markets because of differences between the two markets on the supply side.

Another manner in which snap takes on practical significance is through the impact of switching supply or demand curves. Shifts in one curve can hold drastically different effects, depending on how elastic or inelastic the other curve is. For case, allow ‘s take another expression at the market for fuel. Because demand is comparatively inelastic, at least in the short tally, when OPEC decides to fasten up supply and direct less oil to the U.S. , the inward displacement in the supply curve causes much higher monetary values, with a little bead in measure consumed.

Figure 8: The Effectss of Tightened Fuel Supply on the Market for Car

This is because consumers are non willing to significantly cut their fuel ingestion in the short tally ( intending they are really inelastic in the short tally ) a displacement in the supply curve affects the monetary value much more than the measure. A powerful general regulation can be gather from this illustration: if one curve ( whether supply or demand ) is inelastic, displacements in the complementary curve ( whether demand or supply ) impact monetary value more than measure ; on the impudent side, if one curve is elastic, displacements in the other curve affect measure more than monetary value.

The equilibrium effects of a fuel monetary value on auto gross revenues and monetary values depend on the combined response in this supply concatenation. In the other words, the ascertained equilibrium effects at maker and traders responses together. This implies that vehicles that see a lessening in demand as fuel monetary values alteration, the supply relationship is likely to be reasonably elastic. However, alterations in fuel monetary values may besides increase the demand for certain vehicles. Whether the fringy cost curves for these vehicles are besides level depends on the ability of industries to switch production lines from fuel-inefficient vehicles to fuel-efficient vehicles such as a production of bikes which less use of fuel comparison to autos.


Intimate cognition of the monetary value snap of demand and factors that may change it is of import to both concerns and the authorities. Business would wish to maximise net incomes, and use of monetary value snap of demand to find the best pricing policy is therefore really of import.

The authorities needs to understand monetary value snap of demand to monetary value community goods and services, and to find degrees of revenue enhancement on peculiar merchandises. Business houses demands to understand monetary value snap of demand for the goods they sell in order to make up one’s mind on their optimum pricing policy. If demand were comparatively elastic, the house would cognize that take downing the monetary value would spread out the volume of gross revenues, therefore increasing entire gross. On the other manus, if demand were comparatively inelastic, the house could increase the monetary value, which would besides take to an addition in entire gross, since the bead in gross revenues would be less so proportionate.

Awareness of the snap of demand in different monetary value scopes is of import for finding the best pricing policy for a house and in make up one’s minding whether to alter monetary values. To that extent, concerns frequently engage in statistical market research in order to find consumer penchants, and in peculiar, the monetary value snap of the demand for their merchandise. The authorities needs to understand monetary value snap of demand when pricing the goods and services that it provides for the community ( such as public conveyance menus ) . Further, it besides needs to be able to foretell the effects of alterations in the degree of any indirect revenue enhancements, such as gross revenues revenue enhancements, excise responsibilities and particular levies that is imposes on goods such as intoxicant, baccy merchandises and gasoline. These revenue enhancements and charges raise the monetary value of the goods affected, and the authorities needs to be able to estimate the reactivity of demand in order to gauge accurately the sum of gross they will raise.

5.1 Example of revenue enhancement incidence

Imagine a RM88 revenue enhancement on every unit of auto to the auto manufacturers imposed. If the auto is monetary value inelastic to the consumer ( whereby if monetary value rise, a little demand loss would be accounted for by the excess gross ) , the manufacturer is able to go through the full revenue enhancement on to consumers of autos by raising the monetary value by RM88. In this illustration, consumers bear the full load of the revenue enhancement ; the revenue enhancement incidence falls on consumers. On the other manus, if the auto manufacturer is unable to raise monetary values because the merchandise is monetary value elastic ( if monetary values rise, more demand would be lost than excess gross gained ) , the manufacturer has to bear the load of the revenue enhancement or face decreased grosss: the revenue enhancement incidence falls on the manufacturer. If the auto manufacturer can raise monetary values by an sum less than RM888, so consumers and the manufacturer are sharing the revenue enhancement load. When the revenue enhancement incidence falls on the manufacturer, this load will typically flux back to proprietors of the relevantA factors of production, material supplier and employee rewards.

Where the revenue enhancement incidence falls depends ( in the short tally ) on theA monetary value snap of demandA andA monetary value snap of supply. Tax incidence falls largely upon the group that responds least to monetary value ( the group that has the most inelastic price-quantity curve ) . If the demand curve is inelastic relation to the supply swerve the revenue enhancement will be unreasonably borne by the purchaser instead than the marketer. If the demand curve is elastic relation to the supply swerve the revenue enhancement will be born disproportionately by the marketer.

Figure 9: Inelastic supply, elastic demand: the load is on producer/supplier

Because the demand is elastic, the consumer is really sensitive to monetary value. A little addition in monetary value leads to a big bead in the measure demanded. The infliction of the revenue enhancement causes the market monetary value to increase fromA P without taxA toA P with taxA and the measure demanded to fall fromA Q without taxA toA Q with revenue enhancement. Because the demand is elastic, the measure alteration is important. Meanwhile, inelastic of supply causes the monetary value does n’t alter much. The manufacturer is unable to go through the revenue enhancement onto the consumer and the revenue enhancement incidence falls on the manufacturer of the auto. In this illustration, the revenue enhancement is collected from the manufacturer and the producer/supplier bears the revenue enhancement load. This is known asA back switching.

6.0 Decision

In decision, economic sciences is a societal scientific discipline of human demands and wants that must be satisfied. In market economic systems, consumers can exert their right to purchase whatever they want. However, consumers will merely buy certain goods in certain measures at certain monetary values ; if there is a monetary value alteration, measure demanded will set similarly. This is where monetary value snap of demand comes in, mensurating the reactivity or sensitiveness of the measure demanded to alterations in monetary value utilizing methods such as the entire outgo method.

This relationship explains why authoritiess tend to bear down indirect revenue enhancements, such as excise responsibilities, on those goods that have a comparatively inelastic demand, including intoxicant, fuel and baccy merchandises. On the other manus, if the authorities were to enforce an excise responsibility on a good for which demand is comparatively monetary value elastic, the addition in monetary value caused by the revenue enhancement would take to a more than proportionate bead in gross revenues. As a consequence, the addition in the revenue enhancement may non raise gross significantly.

Practically talking, the authorities frequently has to take such effects into consideration before doing policy alterations. For illustration, if the authorities ‘s end is to restrict imports in order to advance domestic industry, it must first see whether its policy will hold the coveted consequence. If demand for imports is inelastic, an increased duty on imports will merely ensue in increased monetary values without a important bead in measure of imports consumed, which does non profit domestic manufacturers and lone consequences in angry domestic consumers.

Finally, this information is of import to concerns, which need to happen their optimum pricing policy in order to accomplish their end of maximising net incomes, every bit good as to authoritiess, which need to monetary value their ain goods and services and find indirect revenue enhancements imposed on goods and services.
