Demand and Supply in Microeconomics

beg and come out in MicrostintingsIntroductionEconomics is a consider of how to role limited resource to satisfy unlimited populate complimentss. Demand and impart is the two principal(prenominal) concept of the modern economic. Demand is what battalion urgency and preparation is how many goods forthcoming for people want. In free commercialise the value of good is determined by the forms of consumers and how many crossways available for them. As the result of that, when consumers understand the police of conduct and supply they go out guard ability to fix when they can debase a harvesting with low expenditure and the suppliers can set the right charge of this product and decide how many product they result make. In this case study we will evaluate the theory of require and supply. We also give an physical exercise of solicit and supply in solid food trade in capital of Vietnam in storm season.TheoryDemand and supply might be one of the basic concepts o f economics. It is the core of market prudence. Demand is the toll or measure of a product or service desired by consumers. The imply relationship refers to the relationship between the toll and amount of money enquireed, which atomic number 18 the impairment and quantity people willing to pay for. Supply is the derive of products a market get downs. The supply relationship represents the relation between the toll and quantity supplied, which be the price and quantity suppliers willing to wee. Therefore, price is the main concern for demand and supply to consider attachd or deducted, and so demand and supply vary according to the price. According to the law of demand and supply, the higher of a products price the more(prenominal)(prenominal)(prenominal) suppliers will produce and the less(prenominal) people will buy. Beca drill of that, the market price is changes. ( Investopedia news and articles, copyright 2010 )In such a case, the quantity supplied is greater th an the quantity demanded and there is a redundance of the good on the market. From the graph we see that if the unit price is $3 (assuming relative pricing in dollars), the quantities supplied and demanded would be mensuration Supplied = 42 unitsQuantity Demanded = 26 unitsTherefore there would be a surplus of 42 26 = 16 units. The sellers then would lower their price in state to sell the surplus.Suppose the sellers lowered their prices below the equilibrium prognosticate. In this case, the quantity demanded would attach beyond what was supplied, and there would be a shortage. If the price is held at $2, the quantity supplied then would beQuantity Supplied = 28 unitsQuantity Demanded = 38 unitsTherefore, there would be a shortage of 38 28 = 10 units. The sellers then would increase their prices to make more profit.The equilibrium point must be the point at which quantity supplied and quantity demanded argon in balance, which is where the supply and demand curves cross. From th e graph above, one sees that this is at a price of approximately $2.40 and a quantity of 34 units. (NetMBA.com)In general, if the price of a product is at low take, more people want to buy it and the demand will increase. As the result, there will be a shortage. The supplier now will be willing to produce more because people still want to use that product. So the supply increases. It will keep increasing to a point where customers demand and the quantity of that product is equal. Thus, there is a tendency toward an equilibrium point where quantity demanded equals quantity supplied. On the other hand, if the price of a product is at high level, less and less people want to buy it and so the demand decreases. In the end, there will be a surplus. The supplier now will drop down the price in order to attract more customers. This price keeps going down until they sell every(prenominal) out of the surplus. So, the price is moving backward to an equilibrium point where price demanded equ als price supplied.So, how a firm know when to produce more or less? As in THE TIMES 100 article states that An substantial aspect of marketing is knowing what the demand is for your products. All companies engage in marketing activities to find out what the demand for their different products will be. For example, Coca-Cola will want to investigate market trends in the carbonated drinks sector, while a bank will want to find out about the demand for financial services. Armed with this information they are able to make grant pricing decisions based on what other suppliers are doing, as advantageously as on the demand from consumers in the market. about main factors make the change in demandEconomic factors When a country economy is good and people involve more money in their pockets. They liable(predicate) want to consume more and thus the demand will increaseSocial factors As the social trend changes, people might throw away less time for taking care of their houses. Therefo re, they will need to buy more slipstream machines and hire employees to do all the cleaning and readying services. So, there will be more opportunity for firms making washing machine and higher demand for cleaning service.The quantity and the price of combative goods the higher the price of a competitive good, the higher will be the demand for this good as customers change from competitive goods. An example for this is that, if the price of i-phone mobile phone goes up, the demand of other smart phones will increase.Some main factors causing the change in supplyWants it is simply the demand for a particular product. As the demand rises, the supplies will rise also.The number of suppliers If new companies join the market, usually the supply increasesNatural and unpredictable events If earthquakes, floods and sunburn occur, the output likely to drop. Wars, which affect the supply of merchandise raw materials, the segmentation of machinery, may progress anytime.(John Sloman (19 98), and The Times 100, Copyright the Times Newspapers)Demand and Supply in Macroeconomics and MicroeconomicsMacroeconomics is the study of the whole economic activities which include pompousness, recession and unemployment Therefore, it concerns with the hail demand and total supply.If the total demand is high compared to the total supply, rising prices and balance of apportion deficits will occurInflation is the increase of the price level in the whole economy. If there is a rise in demand, suppliers likely react by setting up high prices. by and by all, if the demand is still high, they can sell as good as before and make a bundle of profits. Inflation will happen when all suppliers yet keep their prices at high level.The balance of trade deficits happens when import is greater than export. When the aggregate demand rises, people will nurture a tendency to buy more foreign goods, more imported cars, wines, electronic equipments will be consumed. If the inflation is also high, the domestic goods are even harder to compare with foreign goods. As the result, our goods cannot be consumed not however by our country alone also foreign countries.If the total demand is low compared to the total supply, unemployment and recession will occurRecession is the economic situation when business activities are declined. As the result, fewer and fewer people are willing to spend money. Thus, firms will have a lot of surplus goods. They likely to buy less from the manufacturers, which will decrease the fruit in return.Unemployment will happen if manufacturers do not need to produce anymore.Microeconomics is the study about the individual parts of economy, individual firms. It studies about the demand and supply of specific products and services such as cars, clothes, food, electricians.We cannot make as many goods as want because the lack of resources. There are near choices must be do in our societyWhat should be produced? We dont have enough resources to prod uce as many goods as we want. Therefore, we have to decide how many cars, how many buildings, how many hospitals should be produced?How should things be produced? If there is more than one way to produce thing, we have to decide which is the best.Who will use our products? This is the problem of income. We have to decide what the wage of particular job such as doctor, engineer, farmer Because if they have more money, they likely to consume more (John Sloman, 1998)Case studyIn October of 2008, Ha Noi was flooded by grievous rains. Because the drains did not work effectively as it was supposed to be. People in Ha Noi had a terrible experience because of the scarcity of the food.Learning from that experience, people in Ha Noi today usually store food when a storm is announced coming. As the matter of fact, in the evening of July seventeenth in 2010, the news forecasted that a storm might be coming. However, in the next day, the weather turned normally again. Because of the worry about the scarcity of food, people in Ha Noi already rushed to the super market and bought as many foods as they can. The change of demand and supply made a lot of supermarket out of variant, also the price of the food was treble the supposed price. At some supermarket, people had to struggle, pushed each other just to fill up their fridge. As a result, they had to eat frozen food for months while low price fresh food is selling everywhere. At this point, the market had to suffer the decrease of food demand because people already had food in their fridge.In this case, when a demand surprisingly increase the quantity supply cannot afford to satisfy all the needs kinda of that is the increasing of the price. When the demand drops down, the quantity supply stays the same but the price has to fall to attract more customers.ConclusionNowadays, the real military personnel economy is too complex that even in some cases the law of demand and supply cannot be applied. The market today is chan ging always many individual speculations are getting even more and more uncertainly. Therefore, people shouldnt rush in deciding to buy anything. In my opinion, stock and real estate markets are really risky for those who only add up the market tendency meaning to say the majority of people and dont have enough knowledge of how the economy works. Furthermore, the government should be flexible with the polity to keep the market price at a suitable level so that both customers and suppliers can adapt with, and also avoid inflation and unemployment.
