Different Consumptions And The Impaction Economics Essay
First, from our study we can cognize: what are private, public, replacement and complement goods. And the impact of the difference ingestion is increased export.
Second, we talk about the alterations of the volumes of ingestion after revenue enhancements and subsidies.
Third, we can besides cognize the interaction of domestic ingestion and exports and the differences and similarities of them.
Meanwhile, we will speak about the graduated table of a company with Cobb-Douglas production map.
Then we analyze the ingestion and particularly how income and monetary values have big impact on demand and supply. And we will speak about a mathematical relationship, called the Slutsky equation.
Last but non least, we will distinguish the different snap like price-elasticity, income-elasticity, cross-price-elasticity and supply-elasticity.
Samsung Company is the largest company in Korea. Meanwhile it is a multi-national concern.
In intelligent nomadic phone market, Samsung has already transcends Apple. After less than five old ages of development, Samsung has already alternatively Nokia that in the planetary Mobile phone master 14 old ages. The ground why Samsung is successful is that Samsung can command the market in clip.
Its scheme of merchandise launch is playing an of import function in come ining into intelligent phone market rapidly.
Samsung intelligent phone start from high-end phone, with the advantages of supply concatenation, change productive theoretical account rapidly, take the intelligent mobile phone concatenation highs. But the most of import is Samsung is good at avoid front struggle with Apple. Push-off new production between Apple ‘s merchandise launch.
At the same clip, Samsung besides spread outing China ‘s nomadic portion invariably.
Samsung ‘s merchandise besides really diversified. Although it would non make it best in every field. But at least they are one of the top. 1

The chief content of this study.
Problem solution in the study
This study was commissioned to explicate some of import cognition in the microeconomics. We through describe, analyze and measure that every cognition take us what economic impact. In this study, we will chiefly establish on some information from the book to complete. At the same clip, we besides find some stuff. Every topic we describe the theoretical cognition, so person we besides have the illustration.
In our study, we have six topics. The first one is different ingestion and the impaction ; in this topic we analyze that the difference among public, private, replacement and complement goods. Then give some illustrations to explicate them. The 2nd 1 is the alterations of ingestion volumes after revenue enhancements and subsidies. The monetary value of goods and the gross revenues volume will be changed excessively. The 3rd one is the alterations of domestic ingestion for exports. Then explicate comparative advantages and chance cost. The 4th one is Cobb-Douglas production map, there are three graduated tables: increasing returns to scale, changeless returns to scale, and diminishing returns to scale. The 5th one is income and monetary values have impact on demand and supply. In this one, we explain measure demanded, demanded curve and measure supplied, supply curve. The 6th one is different snap. In this one we detailed introduces price-elasticity, income-elasticity, cross-price snap, and supply snap. In every portion we have illustration to back up theory and person has besides have figures.
In this study we choose Samsung Company as an illustration to explicate some cardinal cognition of microeconomics. We use Cobb-Douglas production map to analysis the graduated table of the Samsung Company. Use the demand and supply to understand the sale volume in the Chinese market of Samsung mobile phone. From these we can cognize why Samsung is successful is that can command the market.
1. Different ingestions and the impaction
1.1 Public goods
Public good is a trade good or service whose ingestion by one individual does non prevent other from besides devouring it. The basic features are deficiency of competition or exclusion or both. For illustration, street lighting is a public good. The good deficiency competition because person utilizing the lighting does non do it less bright for other users. It is besides non-excludable as you can non do people pay for the good as they use it.
Cost for security
Decrease of hazard
For illustration: the security for park. As we know that with the cost for security increasing, the hazard will diminish. At the start, the cost for security put more, the lessening of hazard evidently. But to acquire a measure, the state of affairs will non be changed evidently.
Demand for increased quality of security
We can acquire the other phenomena: demand for increased quality of security and the quality degree.
The ruddy line is demand of A. The bluish line is demand of B. The violet line is the entire demand.
1.2 Private goods
Private good is different from public ingestion. It has the belongingss of competition and exclusion. It can no longer be used after ingestion and is it is easy to do people pay for the good.
All public good deficiency competition, but merely some deficiency exclusion.

1.3 The impaction on goods and services
In the 10 old ages get downing 2010 and be finished 2020, the non-agrarian sector will increase production for domestic ingestion and increased production for export. The entire ingestion is invariable. It means that the agricultural sector will diminish the production. So the industry sector and service sector will increase. The trade goods of export, industry merchandises and some services industry will increase.
1.4 Substitute goods and complement goods
Substitute good is a merchandise that you view as similar or indistinguishable to the 1 you are sing buying. ( Microeconomics P33 )
Complement good is a good that you like to devour at the same clip as the merchandise you are sing purchasing. ( Microeconomics P33 )
We are from the microeconomics cognition of theory to analyse the Samsung ‘s public goods and private goods. First, the public goods for Samsung, it is no uncertainty, are the developing communicating engineering and more and more mature web. At present, the communicating engineering and web are progressively mature. A turning figure of people are familiar with and cognize good with the new engineering. This tendency pushes the nomadic phone ‘s market. Second, the private goods for Samsung, from my point of position, are the Samsung ‘s users and different design. Third, the replacement and complement good. For Samsung, the Mobile of other trade name like iPhone, HTC, Motorola and so on. The complement good for Samsung is some equipment like earpiece or something others.
2. The alterations of ingestion volumes after revenue enhancements and subsidies
When the entire income is invariant, two trade goods ‘ gross revenues volumes are interactive. In other words, when one trade good ‘s gross revenues volume increasing, the other trade good ‘s gross revenues volume will be decreased. We can besides happen that when one trade good ‘s cost increasing, the income will diminish. Oppositely, cutting a trade good ‘s cost, the monetary value will be decreased. It means the gross revenues volume will be increased. Meanwhile, the entire income is increased.
2.1 The alterations of the volume after revenue enhancements
Normally, a trade good be produced and do some net incomes, it need to be added some revenue enhancements. When a trade good adds the revenue enhancements, to the manufacturer, the trade good ‘s cost is bettering. For acquiring the same net incomes, the manufacturer normally will better the monetary value. However, to the consumers, the monetary value improving, person of them will non purchase the merchandise. So the gross revenues volume will be decreased. Thus, though the phenomena, we can acquire that if the revenue enhancements lower, the lower cost, the lower monetary value, and the more gross revenues volume. Oppositely, the more of the revenue enhancements, the volumes of ingestion will diminish.
2.2 The alterations of the volume after subsidies
Sometimes, when a company gets the subsidy from the governmental or other corporate organisations, they will set the money in green goods and can salvage themselves capital. Correspondingly, the cost of trade good will be cut. It means the monetary value is decreased excessively. To the consumers, they will happy to see a lower monetary value and willing to purchase the trade good. So the volumes of ingestion will increase.
3. The alterations of domestic ingestion for exports
Two trade goods will be interacted each other on the monetary value. We can acquire two graphs to demo how it happened. The black lines are before the alterations and the bluish lines are after the alterations.
First, trade good A has an old monetary value PB and has the before supply-demand line as the graph shows. When we change the trade good ‘s monetary value and acquire the new monetary value PA, so we can acquire a new supply-demand line.
Second, we found a new graph which is about other trade good. We get the original budget line. Then we can acquire the production possibility curve and the indifference curve. After the addition of export, we can acquire a new budget line. When the trade good A ‘s supply equal to demand, we can happen the Pareto optimum and the new bluish indifference curve.
MRT = MRS
3.1 The domestic ingestion
The domestic ingestion occupies a big portion in ingestion. When increase the supply goods for domestic ingestion and over a degree, it will be supply exceeds demand. The monetary value of goods will be lessening. But when decrease the supply goods and less a degree, it will be demand exceeds supply. The monetary value of goods will be addition.
3.2 The exports
Export gross revenues are for sale abroad or in another portion of the state. It Approves by the relevant section, gross revenues ( or rent ) to foreign endeavors and persons, including aliens, Chinese of foreign nationality, abroad Chinese and Hong Kong, Macao and Taiwan compatriots trade good lodging country.
3.3 The domestic ingestion and the exports
Sale in domestic market and export stage comparing, in many ways exist great differences. The basic form of export is “ the client + order + production ” . In this manner, the endeavor is fundamentally in conformity with the demands of the client orders for proofing, production, bringing. Thus the nucleus competency of endeavors focus on natural stuff purchase, the production processing and the of import client care, its overall operation to cost, squad scheme petition is non high. The basic form of sale in domestic market is “ the market demand and merchandise portfolio + monetary value combination + gross revenues channel trade name + squad executing ” . In this manner, the endeavor will straight confront altering consumer groups, ingestion construction, channel spouses, so the nucleus competency of endeavors focus on merchandise portfolio, monetary value combination, channel control, trade name building and gross revenues squad build, its overall operation demand is multifaceted, choiceness and systematic.
3.4 Comparative advantages
The comparative advantage is the ability to bring forth a good at a lower chance cost than person else. ( Microeconomics P355 )
We can take an illustration: Japan and Korea produce trade good A and B, they need how much clip.
Japan advantage compared with Korea for B.
Korea advantage compared with Japan for A.
3.5 Opportunity cost
The chance cost is the value of the best alternate usage of a resource. ( Microeconomics P208 )
For A measured in B
For B measured in A
Japan has comparative advantage when bring forthing B. 1 & lt ; 2
Korea has comparative advantage when bring forthing A. 1/2 & lt ; 1
Suppose trade 1A:1B
Common net income
Production additions with 1/2B
In 10 hours, Japan produces 1A and 1B.
In 8 hours, Korea produces 1A and 1/2B.
If Korea produces more A than B, Japan will lose 1/2B for every green goods A and with addition 1A.
Japan has net income from exporting B and importing A.
Korea has net income from exporting A and importation B.
4. Cobb-Douglas production map
A house can increase its end product by constructing a 2nd works and staffing it with the same figure of workers as in the first 1. Whether the house chooses to make, it depends in portion on whether its end product additions less than in proportion, in proportion, or more than in proportion to its inputs. ( Microeconomics P193 )
To foretell the states and parts of the industrial system or big endeavor production and analysis of the development of production a agency of economic mathematics theoretical account referred to as the production map. In economic science is the most widely used a production map signifier, it in mathematical economic sciences and economic metrology the research and applications of has of import place.
There ‘s a expression of Cobb-Douglas:
X = A * KI± * LI?
While: Ten = “ Entire production ”
A = “ Productivity ”
K = “ Capital ”
L = “ Labor ”
I± , I? = “ Output snap ”
When all inputs are increased by a certain per centum and end product additions by that same per centum, the production map is said to exhibit changeless returns to scale.
4.1 Changeless returns to scale
When I± + I?=1. It means the merchandise efficiency will non with the enlarging of the production graduated table better, merely bettering the engineering degrees, the economic benefit will be better.
4.2 Increasing returns to scale
If end product rise more than in proportion to an equal per centum addition in all inputs, the production map is said to exhibit increasing returns to scale. When I±+I?i?z1. It means under the bing technique, to spread out the graduated table of production and increase end products are good.
4.3 Decreasing returns to scale
If end product rises less than in proportion to an equal per centum addition in all inputs, the production map exhibits diminishing returns to scale. When I±+I?i??1. It means under the bing technique, to spread out the graduated table of production and increase end product a pyrrhic triumph.
We think the Samsung Company stay at increasing returns to scale. As a high-end electronic equipment company, Samsung has many first-class staff, advanced engineering and professional equipments. They can command the work flow and productive to salvage the cost. Meanwhile, they cooperate with other spouses. So we believe they have a big gross revenues volume to maintain its graduated table.
5. Income and monetary values have impact on demand and supply
5.1 Demand and provide
Demand and supply are the two words that economic experts use most frequently.
Demand and supply are the forces that make market economic systems work.
Measure demanded is the sum of a good that purchasers are willing and able to buy. We can demo the relationship between monetary value and the measure demanded diagrammatically. A demand curve shows the measure demanded at each possible monetary value, keeping changeless the other factors that influence purchases. Many economic experts claim that the most of import empirical determination in economic science is the jurisprudence of demand: other things equal, when the monetary value of the good rises, the measure demanded of a good falls, and when the monetary value falls, the measure demanded rises.
When the income decreases if the goods of measure demanded are lessening, this sort of goods is called normal good. When the income decreases if the goods of measure demanded are addition, this sort of goods is called inferior good. As income additions, the demand for a normal good will increase. As income additions, the demand for an inferior good will diminish.
When a autumn in the monetary value of one good reduces the demand for another good, the two goods are called replacements. When a autumn in the monetary value of one good increases the demand for another good, the two goods are called complements.
Quantity supplied is the sum of a good that Sellerss are willing and able to sell. We can demo the relationship between monetary value and the measure supplied diagrammatically. A supply curve shows the measure supplied at each possible monetary value, keeping changeless the other factors that influence houses ‘ supply determinations.
Many economic experts claim that the most of import empirical determination in economic science is the jurisprudence of supply: other things equal, the measure supplied of a good rises when the monetary value of the good rises. Although the jurisprudence of demand requires that the demand curve incline downward, there is no jurisprudence of supply that requires the market supply curve to hold a peculiar incline. The market supply curve can be upward sloping, perpendicular, horizontal, or downward inclining. Many supply curves slope upward.
D1 is 2010 twelvemonth demand curve and D2 is 2011year demand curve, because from 2010 to 2011 Samsung invention and bit by bit take the 3G market.
So D1move to D2, Q1 addition to Q2, and the monetary value besides addition, from P1 addition to P2. Application: before 2010 twelvemonth, the nomadic phone market is ever depending on iPhone. But Samsung has launched GALAXY S at 2010. The sale volume of Samsung is greatly increased while GALAXY S gets into the market in 2010.

Figure 5.20 12 16 24 30 40 60
Income consequence Substitution consequence T, Music paths
Entire consequence per one-fourth
M, LiveA musicA P vitamin E rA one-fourth
Substitution consequence: the alteration in the measure of a good that a consumer demands when the good ‘s monetary value alterations, keeping other monetary values and the consumer ‘s public-service corporation invariable. ( Microeconomics P146 )
Income consequence: the alteration in the measure of a good a consumer demands because of a alteration in income, keeping monetary values changeless. ( Microeconomics P146 )
6. Different snap
Elasticity is a step of how much purchasers and Sellerss respond to alterations in market conditions.
The monetary value snap of demand is a step of how much the measure demanded of a good responds to a alteration in the monetary value of that goodi??computed as the per centum alteration in measure demanded divided by the per centum alteration in monetary value.
Percentage alteration in measure demanded
Percentage alteration in monetary value
I”Q/Q I”Q P
= = A-
I”P/P I”P Q
At a point where the snap of demand is zero, the demand curve is said to be absolutely inelastic. At point along the demand curve where the snap is between 0 and -1 is inelastic. At monetary values higher than at the center of the demand curve, the snap of demand is less than negative one, Iµ & lt ; -1. In this scope, the demand curve is called elastic. As the monetary value rises, the snap gets more and more negative, nearing negative eternity. Where the demand curve hits the monetary value axis, it is absolutely snap.
This is monetary value snap of demand. It ‘s descrobed to GALAXY SII gross revenues volume in one month at Chinese market.
When the phone ‘ monetary value is decrease 500 RMB. The measure demanded is increase 700.
So we get two consequences:
From this we can cognize, when the monetary value lessening, the measure will hold big addition.
As income additions, the demand curve displacements. If the demand curve displacements to the right, a larger measure is demanded at any given monetary value. If alternatively the demand curve displacements to the left, a smaller measure is demanded at any given monetary value. ( Microeconomics P73 )
Income-elasticity is step of the per centum alteration in the measure demanded in response to a given per centum alteration in income.
Percentage alteration in measure demanded
I?= Percentage alteration in income
I”Q/Q I”Q Y
= = A-
I”Y/Y I”Y Q
Most of the goods are normal goods: income addition, measure demanded will increase. Due to the measure demanded and income is alteration to the same way. So the income snap of normal good is positive. A few goods are inferior good: income lessening, measure demanded will diminish. Due to the measure and inferior good is alteration to the opposite way. So the income snap of inferior good is negative.
The gross revenues volume is positive with the income. If the consumer ‘s income additions, they will purchase more. It means the gross revenues volume will increases excessively.
6.3 Cross-price snap
Cross-price snap of demand is a step of how much the measure demanded of one good responds to a alteration in the monetary value of another good, computed as the per centum alteration in measure demanded of the first good divided by the per centum alteration in the monetary value of the 2nd goods.
Percentage alteration in measure demanded
Percentage alteration in monetary value of another good
I”Q/Q I”Q P0
= = A-
I”P0/P0 I”P0 Q
When the cross-price snap is negative, the goods are complements. If the cross-price snap is negative, people buy less of the good when the monetary value of the other good addition. ( Microeconomics P74 )
If the cross-price snap is positive, the goods are replacements. As the monetary value of the other good addition, people buy more of this good. ( Microeconomics P74 )
6.4 Supply snap
Price snap of supply is a step of how much the measure supplied of a good responds to a alteration in the monetary value of that good.
Price snap of supply is the per centum alteration in measure supplied ensuing from a per centum alteration in monetary value.
Percentage alteration in measure supplied
I·= Percentage alteration in monetary value
I”Q/Q I”Q P
= = A-
I”P/P I”P Q
We use the footings inelastic and elastic to desribe upward-sloping supply curves, merely as we did for demand curves. IfI·=0, we say that the supply curve is absolutely inelastic: the supply does non alter as monetary value rises. If 0 & lt ; I· & lt ; 1, the supply curve is inelastic: a 1i??increase in monetary value causes a less than 1i??rise in the measure supplied. IfI·=1, the supply curve has a unitary snap: a 1i??increase in monetary value cause a 1i??increase in measure. IfI· & gt ; 1, the supply curve is elastic. If I·is space, the supply curve is absolutely elastic. ( Microeconomics P76 )
When GALAXY SII foremost into Chinese market at 2011-5, we can acquire this figure.
From this figure we can cognize, when the phone ‘s monetary value is 4000, the measure is 500, when the measure addition 1500, the monetary value besides addition to 6000.
Since 3G epoch, the operators ‘ usage market has become the barometer of the intelligent mobile phone market. Compare with Apple rely on one iPhone chief individual market theoretical account, Samsung GALAXYS series mobile phone follow a more flexible Customized manner. It ‘s one of Samsung ‘s Consistent adhere to the nucleus scheme, it can to the full back up different web system operators of different usage demands. After Samsung push-off three different system of 3g version in 2010, Samsung GALAXY SII last to the full supports China ‘s three large operators ‘ customization demand scheme. It ‘s non merely win a more huge usage market for Samsung, it besides make Samsung acquire a greater grade of get operator ‘s acknowledgment and support and laid a solid foundation for Samsung in intelligent mobile phone market.
In this study, we have big of information, information, graphs, application and theory to demo a successful Samsung Company.
We use a batch of microeconomics knowledge to work out and reply the jobs and inquiries. For illustration, the difference of public and private good, Cobb-Douglas production map, the demand and supply curve, different snap and so on.
We can see the success of Samsung Company and its ground of success. Samsung has many good schemes in market and advanced constructs.
