is a branch of economics that studies how individuals, households and firms make decisions to allocate limited resources,[1] typically in markets where goods or services are being bought and sold.Microeconomics examines how these decisions and behaviours affect the supply and demand for goods and services, which determines prices; and how prices, in turn, determine the supply and demand of goods and services.[2][3]Macroeconomics, on the other hand, involves the "sum total of economic activity, dealing with the issues of growth, inflation and unemployment, and with national economic policies relating to these issues"[2] and the effects of government actions (such as changing taxation levels) on them.[4] Particularly in the wake of the Lucas critique, much of modern macroeconomic theory has been built upon 'microfoundations' — i.e. based upon basic assumptions about micro-level behaviour.One of the goals of microeconomics is to analyze market mechanisms that establish relative prices amongst goods and services and allocation of limited resources amongst many alternative uses. Microeconomics analyzes market failure, where markets fail to produce efficient results, as well as describing the theoretical conditions needed for perfect competition. Significant fields of study in microeconomics include general equilibrium, markets under asymmetric information, choice under uncertainty and economic applications of game theory. Also considered is the elasticity of products within the market system.Assumptions and definitionsThe theory of supply and demand usually assumes that markets are perfectly competitive. This implies that there are many buyers and sellers in the market and none of them have the capacity to significantly influence prices of goods and services. In many real-life transactions, the assumption fails because some individual buyers or sellers or groups of buyers or sellers do have the ability to influence prices. Quite often a sophisticated analysis is required to understand the demand-supply equation of a good. However, the theory works well in simple situations.Mainstream economics does not assume a priori that markets are preferable to other forms of social organization. In fact, much analysis is devoted to cases where so-called market failures lead to resource allocation that is suboptimal by some standard (highways are the classic example, profitable to all for use but not directly profitable for anyone to finance). In such cases, economists may attempt to find policies that will avoid waste directly by government control, indirectly by regulation that induces market participants to act in a manner consistent with optimal welfare, or by creating "missing markets" to enable efficient trading where none had previously existed. This is studied in the field of collective action. It also must be noted that "optimal welfare" usually takes on a Paretian norm, which in its mathematical application of Kaldor-Hicks Method, does not stay consistent with the Utilitarian norm within the normative side of economics which studies collective action, namely public choice. Market failure in positive economics (microeconomics) is limited in implications without mixing the belief of the economist and his or her theory.The demand for various commodities by individuals is generally thought of as the outcome of a utility-maximizing process. The interpretation of this relationship between price and quantity demanded of a given good is that, given all the other goods and constraints, this set of choices is that one which makes the consumer happiest.[edit] Modes of operationIt is assumed that all firms are following rational decision-making, and will produce at the profit-maximizing output. Given this assumption, there are four categories in which a firm's profit may be considered.A firm is said to be making an economic profit when its average total cost is less than the price of each additional product at the profit-maximizing output. The economic profit is equal to the quantity output multiplied by the difference between the average total cost and the price. A firm is said to be making a normal profit when its economic profit equals zero. This occurs where average total cost equals price at the profit-maximizing output. If the price is between average total cost and average variable cost at the profit-maximizing output, then the firm is said to be in a loss-minimizing condition. The firm should still continue to produce, however, since its loss would be larger if it were to stop producing. By continuing production, the firm can offset its variable cost and at least part of its fixed cost, but by stopping completely it would lose the entirety of its fixed cost. If the price is below average variable cost at the profit-maximizing output, the firm should go into shutdown. Losses are minimized by not producing at all, since any production would not generate returns significant enough to offset any fixed cost and part of the variable cost. By not producing, the firm loses only its fixed cost. By losing this fixed cost the company faces a challenge. It must either exit the market or remain in the market and risk a complete loss. [edit] Market failureMain article: Market failureIn microeconomics, the term "market failure" does not mean that a given market has ceased functioning. Instead, a market failure is a situation in which a given market does not efficiently organize production or allocate goods and services to consumers. Economists normally apply the term to situations where the inefficiency is particularly dramatic, or when it is suggested that non-market institutions would provide a more desirable result. On the other hand, in a political context, stakeholders may use the term market failure to refer to situations where market forces do not serve the public interest.The four main types or causes of market failure are:Monopolies or other cases of abuse of market power where a "single buyer or seller can exert significant influence over prices or output". Abuse of market power can be reduced by using antitrust regulations.[5] Externalities, which occur in cases where the "market does not take into account the impact of an economic activity on outsiders." There are positive externalities and negative externalities.[5] Positive externalities occur in cases such as when a television program on family health improves the public's health. Negative externalities occur in cases such as when a company’s processes pollutes air or waterways. Negative externalities can be reduced by using government regulations, taxes, or subsidies, or by using property rights to force companies and individuals to take the impacts of their economic activity into account. Public goods are goods that have the characteristics that they are non-excludable and non-rivalous and include national defense[5] and public health initiatives such as draining mosquito-breeding marshes. For example, if draining mosquito-breeding marshes was left to the private market, far fewer marshes would probably be drained. To provide a good supply of public goods, nations typically use taxes that compel all residents to pay for these public goods (due to scarce knowledge of the positive externalities to third parties/social welfare); and Cases where there is asymmetric information or uncertainty (information inefficiency).[5] Information asymmetry occurs when one party to a transaction has more or better information than the other party. For example, used-car salespeople may know whether a used car has been used as a delivery vehicle or taxi, information that may not be available to buyers. Typically it is the seller that knows more about the product than the buyer, but this is not always the case. An example of a situation where the buyer may have better information than the seller would be an estate sale of a house, as required by a last will and testament. A real estate broker purchasing this house may have more information about the house than the family members of the deceased. This situation was first described by Kenneth J. Arrow in a seminal article on health care in 1963 entitled "Uncertainty and the Welfare Economics of Medical Care," in the American Economic Review. George Akerlof later used the term asymmetric information in his 1970 work The Market for Lemons. Akerlof noticed that, in such a market, the average value of the commodity tends to go down, even for those of perfectly good quality, because the buyer has no way of knowing whether the product they are buying will turn out to be a "lemon" (a defective product). [edit] Opportunity costMain article: Opportunity costAlthough opportunity cost can be hard to quantify, the effect of opportunity cost is universal and very real on the individual level. In fact, this principle applies to all decisions, not just economic ones. Since the work of the Austrian economist Friedrich von Wieser, opportunity cost has been seen as the foundation of the marginal theory of value.Opportunity cost is one way to measure the cost of something. Rather than merely identifying and adding the costs of a project, one may also identify the next best alternative way to spend the same amount of money. The forgone profit of this next best alternative is the opportunity cost of the original choice. A common example is a farmer that chooses to farm his land rather than rent it to neighbors, wherein the opportunity cost is the forgone profit from renting. In this case, the farmer may expect to generate more profit himself. Similarly, the opportunity cost of attending university is the lost wages a student could have earned in the workforce, rather than the cost of tuition, books, and other requisite items (whose sum makes up the total cost of attendance). The opportunity cost of a vacation in the Bahamas might be the down payment money for a house.Note that opportunity cost is not the sum of the available alternatives, but rather the benefit of the single, best alternative. Possible opportunity costs of the city's decision to build the hospital on its vacant land are the loss of the land for a sporting center, or the inability to use the land for a parking lot, or the money that could have been made from selling the land, or the loss of any of the various other possible uses—but not all of these in aggregate. The true opportunity cost would be the forgone profit of the most lucrative of those listed.One question that arises here is how to assess the benefit of dissimilar alternatives. We must determine a dollar value associated with each alternative to facilitate comparison and assess opportunity cost, which may be more or less difficult depending on the things we are trying to compare. For example, many decisions involve environmental impacts whose dollar value is difficult to assess because of scientific uncertainty. Valuing a human life or the economic impact of an Arctic oil spill involves making subjective choices with ethical implications.

我国经济经历了三十多年的快速发展，在取得了发展奇迹的同时也存在着很多问题。下面是我为大家精心推荐的经济类学术论文（英文），希望能够对您有所帮助。经济类学术论文（英文）篇一 The Likonomics “Likonomics”, the term to describe Chinese Premier Li Keqiang`s economic policy. Was coined on June 27 by three economists at Barclays Capital. Like "Thatcherism", "Reaganomics", and more recently “Abenomics”, "Likonomics" has become the buzzword to describe the implications of China's new economic program. And what is “Likonomics”? The Barclays Capital`s economists also give our a explain, “Likonomics” was a series of measures adopted by the State Council. The measures were passed to ensure the sustainability of China`s economy. “which could be summarized as "Likonomics", consists of three key pillars: no stimulus, Deleveraging and structural reform." It is mean the China need to free the market, and stop the government control the market. And this new police is a long-term objectives, so the next three years the grew rate of Chinese quarter of Economic will be reduced at least 4%. “Since assuming office in mid-March, Premier Li Keqiang has taken a different policy path. Its key economic policy framework, which could be summarized as "Likonomics", consists of three key pillars: no stimulus, deleveraging and structural reform.”(China Daily 07/05/2013 page9 by Huang Yiping). In the news, we know the three solutions, “no stimulus”, “Deleveraging” and “structural reform”. The “stimulus” mean the government in the short time,following the liabilities or expand the money supply to stimulate the economy, but at the same time the inflation also coming, So the first way is to decrease the Chinese inflation. And the second solution is “Deleveraging”, this solution`s meaning is “repay”, repay the money that borrow before the economic crisis, at the same time the most assets, such as stocks, bonds, real estate the prices of those assets will be decrease, and the country`s economy also will be reduced. The last solution is the “structural reform”, everyone know the government has no able to control the market, because the government cannot get all information for the government, but it just is the half reason for this solution, the other part is the “corruption” in the Chinese government system, the power official have able to control the economy. So the Premier Li Keqiang build the “free trade zone” in Shanghai, in this area no one can control the economy, that mean every thing happen in this area are all form the market`s self adjusting. In fact the words “no stimulus”, “Deleveraging” and “structural reform” are professional, so I use my own word to explain the “Likonomics”. I have four steps. First step, only “fight” the inflation and do not care the Chinese Economy grow rate, right now in China the RIBOR between banks is from 2% increase to 30%, it is effective to stop the banks`s venture investment, because when the RIBOR increase the bank have to keep the “working capital” in their own hand, they have no enough able to pay the extremely high interest rate, so that the total money in the market going to decrease. But at the same time the China “Total Social Financing ” it reduced 43%. Secondly step, is decrease the TAX, as same as the picture show as, right now the Chinese tas price is stand on the point A, and if the government reduced the tax price the total tax revenue will be increase. Thirdly step, is free the coal`s price, because in China the coal is the most important resource, people use the coal to generate electricity, warm and others, but on the coal have 88 kinds of tax, and the government disagree to trade the coal with other countries, so that if the government stop to control the coal`s price, the price will be decrease, then the burden of enterprises will accordingly drop. Fourth step, and also the last step is talk about the government control. We all know, that if the government control the market the efficiency of market will goes down, because the government cannot get all the information in the market. So the “Free trade zone” was born in Shanghai, in this zone the government cannot control, and the other large enterprise also cannot intervene, it is a 100% free market. The Premier Li is use this way to break the bureaucracy in China. Right now, the China is the fastest develop country in the world, and at the same time the stagflation also is coming. So the Premier Li use the extremely hard cost to stop the Chinese inflation increase. We don`t know what will be happen in the after ten years, even twenty years, the China, stand on the top of world, every action of China can have able to effect the international economic.

They are a large community Taizi vally, two medium communities Shanshuiqing and Nuode internation, and two small communities, Shanhaicuilu and Ray. 0755. Residents Quantity:2500 families. The supermarket quantity: before 2009, there's a Huarun for us to buy something we need, but it moved after property right had transfered . Before 2010,there are no formal large supermarket. Supermarkets in geographical position from this area is far place but they has some small buses to transport customers, but I live in the area which just has some stores and a large farmer's market. By the end of 2010, Easy life opened and Baijia opened in early 2011. They are opened for residents’ everyday necessities demand. In March 2011,Easy life went out of business but Baiji’s business is booming.This article will mainly discuss the reason of Easy life closed and consumers choice problem. 一.What decided they fate? 1. From market supply and demand we can see that when Easy life and Baijia existing at the same time, there are supply greater than demand . 2. When market supply greater than demand, which decide their fate is consumer preferences. First, shopping environment from view, consumer preferences in purchasing Baijia because it has a comfortable environment for comsumer to buy something. And at this point, Baijia do better than Easy life, such as: the ground very clean, there was nothing in the cart like residual vegetables or other things, shelves are very neat and clean, air indoor is very good.moreover from display of goods to see, though two of the supermarket goods no matter from varieties or to brand are familiar, but Baijia do better than Easy life and obviously the main problem is that Easy life’s commodity classification isn’t science, shelves has many unused space, etc. In addition to attract consumers from some of the factors, such as the lights, warm lamplight can make the fruit and vegetable appear very fresh, and can still make consumer feel very comfortable and it can also stimulate consumer to buy someting, so consumers are willing to spend more time to purchase goods.But choose the cool color light will make the fruit and vegetable seems not fresh and color looks wrong, the most important is the cool color light may make consumers feel unwell, consumers don’t want to stay in the supermarket any more, that is certainly will reduce consumer’s more consumption. At this point Baijia will do better than Easy life. The above is from thing’s logical thinking , however, but when we use economic theory to treat Easy life closed and there is something we cann’t understand. Because of Easy life is at the side of the road where there is a large community, a medium-sized community and a small community. From the factor of buy something convenient to see, people actually are more willing to go to Easy life, because it does not need to cross the road. And the cashier of Easy life work more efficiently than Baijia, the bill. And this reduce customer unnecessary waiting time. The most important advantages of Easy life that the price of same goods is cheaper than relative to the best goods cheaper than Baijia. So why are these relationships to the immediate interests of consumers advantage did not let Easy life’s business thriving? Instead of "advantage" that is blatant and why let Baijia’s business thriving? Personally, I think, this is the result of irrational consumer behavior! Economics of three assumptions, the most controversial is rational man hypothesis.看了“经济类学术论文（英文）”的人还看： 1. 经济类新闻学术论文 2. 经济类词汇中英对照 3. 经济类学术论文范文 4. 英文翻译学术论文 5. 英语学术论文范文

The Chinese economy continually growth and the world economics growth asthenia as well as US dollar unceasing depreciation, specially American Government in the situation which the domestic unemployment rate and the international trade trade deficit rise unceasingly, American some people the American manufacturing industry worker will be unemployed with the China and America trade deficit reason sums up as the Renminbi exchange rate First, the Renminbi exchange rate is not the China and America trade deficit principal factor 1st, China and America balance of trade series analysis The China and America statistical figure difference so greatly mainly has two aspect reasons: (1)th, when American statistics China through Hong Kong partial transit trade repetition computation in China to US's exportation aspect. (2)th, American trade data collection process existence very many questions. 2nd, the China and America trade deficit is any reason creates (1)th, American Government to the high-tech product exportation control policy, is the Chinese and American trade not balanced important reason. (2)th, US the multinational corporation which invests in China is a balance of trade important reason.Although China has the high trade surplus to US, but these trade surplus very major part comes from US in China's multinational corporation, demonstrated according to China's statistical data: In the Chinese import and export volume 56% is realizes by the overseas-funded enterprise, China is becoming US's multinational corporation to reduce the production cost, one of increase profit main channels. (3)th, US's trade statistics report has not collected the multinational corporation the American domestic investment income computation 3rd, tucks up the American foreign trade deficit the veil US's import comes from massively our country company in the production line which overseas sets up, in other words, American Multinational corporation from the overseas subsidiary company input cargo, the realistic trade many all is the company and the company, but non-country and country single card trade. English economist Julius on once to American trade revenue and expenditure statistics in, if adds on its overseas subsidiary company in the local repetition computation, that, in 1986 US's trade revenue and expenditure on became 57,000,000,000 US dollars earnings from 144,000,000,000 US dollars trade deficits.Also according to the American Department of commercial affairs statistics, in 1995 the American Multinational corporation subsidiary company sales volume surpassed 210,000,000 US dollars, in addition commodity service export amount 794,000,000,000 US dollars, nearly amounted to 3 ten thousand hundred million US dollars in the same year, but the foreign country exports and the foreign corporation to US in US's subsidiary company internal sales volume sum total is 2,400,000,000,000 US dollars, today US is not the world biggest trade deficit country, but was in the world one of minority several big trade surplus countries. US to the overseas export amount and the American Multinational corporation's in foreign market sale, both sum 2002nd year amounted to 3,000,000,000,000 US dollars.Same time, US's import amount and the foreign multinational corporation's in American market sale, both the sum is 2,400,000,000,000 US dollars, thus has created US to various countries trade gross profit 600,000,000,000 US dollars, this is analyzes when the American foreign trade deficit should comprehensively grasp the question the essence to be at. 4th, US trade deficit true reason (1) 20th century 70's, because two petroleum crises cause the world oil price two large rises, in addition comes from Japanese and the developing nation strong economical competitive power and the US dollar exchange rate strong trend of, these all caused the American commodity, the service trade deficit to achieve 152,000,000,000 US dollars peaks in 1987. (2) US worsens the low savings ratio, US must raise the construction fund from the international money market, namely allows temporary credit the fund to carry on the massive investment construction. (3) American Multinational corporation “the person on one's own side” who acts in the American import trade the role, namely the partial trade deficit in fact is “the commodity backflow”. China and US are a supplementary economy, maintains the existing exchange rate system is the win-win situation
