Such as war, natural disasters, man-made disasters, these factors do not occur frequently in the economy, but with the same characteristics, these economists do not occur frequently, and temporary effect called virtual variables.4 instrumental variable method: instrumental variable method takes the predetermined variable as instrumental variable instead of the endogenous variable in structural equation as explanatory variable, in order to reduce the correlation between random item and explanatory variable.Identification of 5 simultaneous equations: a single equation that constitutes a simultaneous equation has only a statistical form in its simultaneous equations, and this equation is known to be identifiable, otherwise it is called non recognizable. If every equation in the simultaneous equation can be identified, this simultaneous equation is called identity, otherwise it is called non recognizable.Two, simple answer1 the classical assumption that the least square method should be satisfiedAnswer: (1) the mean of random items is zero;(2) random sequence non correlation and heteroscedasticity;(3) explanatory variables are non random, and if random, they are not related to random items;(4) there is no multicollinearity between explanatory variables.2 the steps of applying econometrics to solve economic problemsAnswer: 1) building models;2) estimation parameters;3) verification theory;4) use modelThe reason for the existence of 3 sequence correlationSequence correlation: that is, the random term U is related to other previous terms. It is called sequence correlation or autocorrelation.The cause of existence:First of all, with the continuous problem in economic life and time, namely the repetition time repeated, therefore, the explanatory variables associated with.Secondly, the error of model selection is established, which makes the explanatory variables relevant.Finally, when the model is established, the random term has autocorrelation, and the sequence has autocorrelation.The method of economic structure test in 4 regression analysisChow puts forward the following test method:Firstly, two samples were merged to form the sample of the number of observation value +, and the model (4.25) was regressed, and the regression equation was obtained:(4.28)The sum of squares of residuals is obtained, and the degree of freedom is + -k-1,Here K is the number of variables explained.Secondly, the use of two small sample given above, respectively (4.25) of the regression analysis, the regression equation respectively (4.26) and (4.27), calculated the sum of squared residuals, respectively, the degree of freedom for -k-1 and -k-1 respectively.Then, according to the sum of squares of residuals, the following statistic is constructed:~ F (k+1, + -2k-2) (4.29)Using statistical (4.29) test (4.26), (4.27) the significant similarities and differences, that is, test hypothesis: (j=0, 1,2,... K).Given the significant level (such as =0.05, =0.01), the F distribution table with the first degree of freedom as k+1 and the second degree of freedom as the + -2k-2 is obtained, and the critical value is obtained.If rejected, that (4.26), (4.27) there is a significant difference, the economic relations of the two or two samples reflect different, we say that the changes in the economic structure; on the contrary, we believe that the economic structure is relatively stable.Some properties of the 5 random perturbation term:1. the complex represented by many factors on the explanatory variable Y;2., the influence direction of Y should be different, there are positive and negative;3. as a secondary factor, the total average impact on Y may be zero;The effect of 4. on Y is non trending and stochastic.Three computational analysis1., according to the following information, study the income and consumption of farmers in Hebei province.Particular yearItem 1994199519961997 1998199920002001 20022003Per capita net income of farmers (100 yuan) 111721232424252627 29Living expenses (100 yuan) 811141413131414151According to economic theory, there is a correlation between farmers' living expenditure and their net income. The basic source of farmers' consumption expenditure lies in their net income, so the increase of per capita net income of farmers is the reason for the increase of their living expenses. In addition, farmers' living expenses are also affected by savings, psychological preferences and other factors, so the model is regression model.If Ct is the farmer's consumption expenditure, and Y is the net income per capita of farmers, the following regression model can be establishedCt=c+aYtDependent Variable: CTMethod: Least SquaresDate: 12/15/97 Time: 16:44Sample: 19942003Included observations: 10Variable Coefficient Std.

(n), or Var (U) Var (U) (I J), then we call the random perturbation term UI has heteroscedasticity.Source: 1. model omitted economic variables, the measurement error of 2.The consequence of heteroscedasticity: the 1. parameter estimator is still linear unbiased, but not valid. 2. test failure based on t distribution and F distribution. The variance of 3. estimator increases, and the prediction accuracy decreases.Inspection: Inspection (Goldfeld - Quart Goldfield - Quandt G - Q test) test in 1965 by S.M.Goldfeld and R.E.Quandt proposed. This test method is applicable to large samples, usually require the capacity of n should be 30 or the number of observations is to estimate the parameters of more than 2 times(i.e., sample size is much larger than the N model included explanatory variables two times large numbers above). To test heteroscedasticity should meet the following conditions: first, using the method of random perturbation UI obey the normal distribution, and the variance of UI increased with a certain explanatory variables; second, random perturbation UI no serial correlation, namely E (uiuj) =0 (I J). The test method is mainly F test.The test hypothesis H0: UI is equal variance, and the alternative assumption is that H1: UI is heteroscedastic, and the specific steps of G - Q test are as follows:1. will explain the observed value of the variable Xi in absolute ascending order, be interpreted correspond to the variables of Xi Yi.2. the Xi are arranged in C values by deleting the centre of the remaining N-C observations is divided into two sub samples of the same capacity, the capacity of each sub sample respectively, a sub sample which is the larger part of the corresponding observation value, the other is a relatively small part of the observed value. It should be noted that the determination of the C value is not arbitrary, and it is determined by experiments by Goldfeld and Quandt. For the sample size when n is greater than 30, the number of C for the entire sample number 1/4 by deleting observations (e.g., sample size is 48, c=, n=12, removal of the observation value is 12, then the two sub sample volume respectively =18).3. the least squares method is used to calculate the regressionequation of the two sub samples, and then the corresponding residual sum of squares is calculated respectively. The sum of squares of residuals is the sum of the residuals of the sub samples with larger sample value, and their degree of freedom is -k, where k is the number of explanatory variables in the econometric model.4. establish statistics:F= can prove that F=RSS2/RSS1 ~ F (), that is, it follows the F distribution of degrees of freedom respectively. Obviously, if the two sub sample variance is equal, the value of F is close to 1, show that UI has equal variance; if the variance is not equal, according to the pre condition of RSS2 is greater than RSS1, F-measure should be greater than 1, then UI has heteroscedasticity, so we can use the F test to verify whether UI has heteroscedasticity of. That is, for the given significance level, the F distribution table is obtained corresponding critical value, if F>, reject H0, accept H1, that is, UI has heteroscedasticity; if F<, then accept H0, UI has equal variance.。

According to the factor-endowment theory, a nation will export that good for which a large amount of the relatively scarce resource is used.T F 5. According to the factor-endowment theory, a nation will import that good for which a large amount of the relatively abundant resource is used.T F 6. The Heckscher-Ohlin theory suggests that land-abundant nations will export land-intensive goods while labor-abundant nations will export labor-intensivegoods.T F 7. The Heckscher-Ohlin theory contends that over a period of years a country that initially is an exporter of a product will become an importer of that product.T F 8. The Heckscher-Ohlin theory emphasizes the role that demand plays in the crea-tion of comparative advantage.T F 9. The factor-endowment theory asserts that with specialization and trade there tends to occur an equalization in the relative resource prices of trading partners. T F 10. According to the factor-endowment theory, international specialization and trade cause a nation’s cheap resource to become cheaper and a nation’s expensiveresource to become more expensive.T F 11. Fears about the downward pressure that cheap foreign workers place on U.S.wages have led U.S. labor unions to lobby for import restrictions such as tariffsand quotas.81 / 12T F 12. According to the factor-price-equalization theory, international trade results in the relative differences in resource prices between nations being eliminated.T F 13. Empirical testing by Wassily Leontief gave support to the Heckscher-Ohlin theory of trade.T F 14. The Leontief Paradox was the first major challenge to the product-life-cycle theory of trade.T F 15. The Leontief Paradox suggested that, in contrast to the predictions of the factor-endowment theory, U.S. exports were less capital-intensive than U.S. import-competing goods.T F 16. The specific-factors theory analyzes the income distribution effects of trade in the short run when resources are immobile among industries.T F 17. Owners of resources specific to export industries tend to lose from international trade, while owners of factors specific to import-competing industries tend togain.T F 18. The factor-price-equalization theory is a short-run version of the specific-factors theory.T F 19. With economies of scale, specialization in a few products allows a manufacturer to benefit from longer production runs which lead to decreasing average cost.T F 20. With decreasing costs, a country has an incentive to partially specialize in the product of its comparative advantage.T F 21. By widening the size of the domestic market, international trade permits compa-nies to take advantage of longer production runs and increasing efficiencies suchas mass production.T F 22. The theory of overlapping demands applies best to trade in manufactured goods. T F 23. Decreasing cost conditions lead to complete specialization in the production of the commodity of comparative advantage.T F 24. According to Staffan Linder, the factor endowment theory is useful in explaining trade patterns in manufactured goods, but not primary products.T F 25. The theory of overlapping demands asserts that trade in manufactured goods is stronger the less similar the demand structures of two countries.T F 26. The theory of overlapping demands contends that international trade in manufac-tured products is strongest among nations with similar income levels.T F 27. According to the theory of overlapping demands, trade in manufactured goods would be greater among two wealthy countries than among a wealthy countryand a poor country.T F 28. Recent studies of U.S. resource endowments indicate that the United States is most abundant in unskilled labor, followed by semiskilled labor and skilled labor.T F 29. Intraindustry trade would occur if computers manufactured in the United States by IBM are exported to Japan while the United States imports computers manu-factured by Hitachi of Japan.T F 30. Because seasons in the Southern Hemisphere are opposite those in the Northern Hemisphere, one would expect intraindustry trade to occur in agricultural products.T F 31. Intraindustry trade can be explained by product differentiation, economies of scale, seasons of the year, and transportation costs.T F 32. According to the theory of intraindustry trade, many manufactured goods undergoa trade cycle in which the home country initially is an exporter and eventuallybecomes an importer of a product.T F 33. The product-life-cycle theory applies best to trade in primary products in the short run.T F 34. According to the product-life-cycle theory, the first stage of a product’s trade cycle is when it is introduced to the home market.T F 35. According to the product life cycle theor y, the last stage of a product’s trade cycle is when it becomes an import-competing good.T F 36. Ricardo’s theory of comparative advantage is a static theory that does not con-sider changes in international competitiveness over the long run.T F 37. Dynamic comparative advantage refers to the creation of comparative advantage through the mobilization of skilled labor, technology, and capital.T F 38. Industrial policy seeks to direct resources to declining industries in which pro-ductivity is low, linkages to the rest of the economy are weak, and future com-petitiveness is remote.T F 39. Europe’s jumbo-jet manufacturer, Airbus, has justified receiving governmental subsidies on the grounds that the subsidies prevent the United States from becom-ing a monopoly in the jumbo-jet market.T F 40. The imposition of pollution-control regulations on domestic steel manufacturers leads to decreases in production costs and an improvement in the steel manufac-turers’ competitiveness.T F 41. Empirical studies conclude that U.S. environmental policies are a more important determinant of trade performance than capital, raw materials, labor skills, andwages.T F 42. Most developing countries have pollution-control laws and enforcement policies that are more stringent than those of the major industrial countries.83 / 12T F 43. Although the theory of comparative advantage explains trade in manufactured goods, it has no explanatory value for trade in business services.T F 44. When transportation costs are added to our trade model, the low-cost exporting country produces less, consumes more, and exports less than that which occurs inthe absence of transportation costs.T F 45. When transportation costs are added to our trade model, the degree of specializa-tion in production between two countries increases as do the gains from trade.T F 46. In the absence of transportation costs, free trade results in the equalization of the prices of traded goods, as well as resource prices, in the trading nations.T F 47. In industries where the final product is much less weighty or bulky than the materials from which it is made, firms tend to locate production near resourcesupplies.T F 48. Industrial processes that add weight or bulk to a commodity are likely to be located near the resource market to minimize transportation costs.T F 49. A product will be traded only if the cost of transporting it between nations is less than the pretrade difference between their relative product prices.T F 50. Generally speaking, transportation costs are more important than production costs as a source of comparative advantage.T F 51. The product-life-cycle model contends that when a new product is introduced to the home market, it generally requires low-skilled labor to produce it.T F 52. According to the product life cycle model, comparative advantage shifts from cheap-labor countries to high-technology countries after a manufactured goodbecomes standardized.ANSWERSAnswers to Multiple-Choice Questions1. d2. d3. c4. b5. b6. a7. b8. a9. a10. b 11. a12. c13. c14. d15. b16. c17. a18. a19. b20. a21. b22. a23. d24. c25. d26. c27. b28. a29. c30. d31. a32. d33. b34. b35. d36. a37. d38. d39. c40. c41. a42. b43. d44. d45. c46. d47. d48. a49. d50. bAnswers to True-False Questions1.

Does factor price equalization occur in the real world?Answer: In the real world, differences in factor prices tend to exist. Different technologies, imperfect markets, transportation costs, and trade barriers may prevent factor prices from equalizing among nations.2. What is the focus of the product life cycle theory, and where is it applicable?Answer: The product life cycle theory focuses on the role of technological innovation as a key determinant of trade patterns. It applies to manufactured goods.ESSAY QUESTIONS1. Explain how immigration and trade may worsen wage inequality, and how college educa-tion may mitigate against that.Answer: Trade tends to increase the demand for skilled workers relative to unskilled workers, thus worsening wage inequality. Immigration of unskilled workers decreases the supply of skilled workers relative to unskilled workers, thus worsening wage inequality. Alternatively, college education increases the supply of skilled workers relative to unskilled workers, thus reducing wage inequality.2. How does Staffan Linder explain world trade patterns?Answer: Linder offers two explanations of world trade patterns. Trade in primary products conforms well to the factor-endowment theory. However, trade in manufactured goods is best explained by overlapping demand structures among nations. For manufactured goods, the basis for trade is stronger when the structure of demand in two nations is more similar, due to similar per-capita incomes.85 / 12。
经济学Question 1
Candidates should explain clearly what free trade is. An explanation would explain that traders make transactions without interference from governments, ie without barriers. Candidates may include examples of free trade agreements and free trade talks to illustrate their explanation. Scottish Qualifications Authority 8 HN Assessment Exemplar/ F86E 35/AEX001 V1.0 Title: Economics 2: The World Economy September 2010Candidates should explain clearly what is meant by absolute and comparative advantage.

经济学问答整理
第一节经济学及其有关概念一、经济学与经济活动!经济学概念两种形式1934年罗宾斯曾给出一个关于经济学的定义:经济学是研究人类行为的一门科学,它考察人们如何处理目的与具有多种用途的的稀缺性手段之间的关系。
这一定义被认为是有关经济学的经典定义。
具有类似思想的另一种定义是:经济学是研究个人、企业、政府以及其他组织如何在社会内进行选择,以及这些选择如何决定社会稀缺资源的使用的科学。
这个定义较为普遍,在一些常用的教科书中均可见到。
这两个定义之间最大的共同之处是强调资源稀缺性问题。
人们的欲望是无穷的,但用于满足人们各种各样欲望的资源是稀缺的,因此,人们时刻都必须做出选择。
如何将稀缺的资源在商品和劳务的生产以及商品和劳务的消费中进行最有效的分配,就成为经济学研究的重要课题。
!机会成本:一种资源一旦被用于某种商品的生产，也就意味着放弃生产另外一种商品的机会,使用一种资源的机会成本是指把该资源投入某一特定用途以后所放弃的其他用途中所能获得的最大收益。
tips与选择相联系的另一个经济学概念是经济活动。
经济活动就是各种经济单位使用资源或生产要素进行生产并相互交换以满足人们需要的行为。
经济活动的目的是增加经济福利和财富,生产的最终目的是为了消费。
二、微观经济学和宏观经济学？问题微观经济学的涵意?！答案微观经济学是经济学的一个重要部分,又被称为“小经济学”。
微观经济学的研究对象是个体经济单位。
个体经济单位指单个消费者、单个生产者和单个市场等，它所涉及的是个体经济单位如何做出决策，以及这些决策受到哪些因素的影响。
个体经济单位的选择受到价格的影响，因此，微观经济学的中心问题是价格问题，微观经济学也被称为价格理论。
Tips:微观经济学最基本的假设有两条：第一，理性人的假设,也被称为“经济人”的假设。
“经济人”在一切经济活动中的行为都是以利己为动机的,力图以最低的经济代价去追逐个人最大的经济利益。
一般而论,经济学中通常假定理性的消费者为了自身的满足为最大,而生产者则为了获取最大化的利润。
经济学问答题
问答题（12）1、现实中存在这样一些现象：上游的造纸厂污染下游的养渔场，炼钢厂污气的排放损害了附近居民的身体健康，同寝室同学放录音机听歌影响其他人的休息，等等。
请问经济学上是如何定义该类现象的？经济学上有什么解决该类问题的办法？(外部影响)(外部影响。
经济学上解决外部影响的政策有：使用税收和津贴；使用企业合并的方法；使用规定财产权的办法；最后一种可以看成是更加一般化的所谓科斯定理的特例。
)2、一国资本流动、通货膨胀、利率变化对本国汇率有何影响？一国的通货膨胀率高的国家的货币会贬值，通货膨胀率低的国家的货币会升值。
不同货币购买力的比率就构成了相互间汇率的基础。
尽管货币的购买力难以衡量，但由于货币购买力与价格水平成反向关系。
因此价格水平变化就会导致汇率的变动。
（国际收支顺差，获得外币大于送出去本币，国外获得更多的货物或者服务，国内获得更多的购买力，排除国外投资考虑，会有更多的外币换成本币，外币需求更旺点，所以本币升值；通货膨胀情况下，国内物价激增，购买力变弱，更多资金外流，本币会贬值，从而增加出口；利率升高，套利外币资金流入，换成本币后享受更高利率，本币还是会升值。
但这三点并不是独立的，三个条件交叉出现时候就要看综合情况了。
比如，我国2010年底国际经常项目仍然是顺差，而且利率上调了，但是通货膨胀严重，中国的人民币就处于升值状态，但是这些是因为人民币被低估的请款下发生的，美国的量化宽松政策也是对国际收支不平衡的一种调整，逼着人民币升值，否则就要深受通货膨胀之苦。
权衡之下，中国决策者决定还是人民币升值抑制物价，稳定社会经济发展。
）3、为什么在市场均衡状态下，买者和卖者都获得最大的满足？当需求等于供给时，市场处于均衡。
所以均衡点位于需求曲线和供给曲线的交点上。
需求曲线具有以下两种含义：(1)表示在各种可能的价格下，消费者愿意而且能够购买的商品数量；(2)表示对于各种数量的商品，消费者愿意支付的最高价格。

经济学问答题
边际报酬递减的原因对于任何产品的短期生产来说，他的可变要素和固定不可变要素的投入量之间存在一个最佳的数量组合比例。
随着可变要素的增加，可变要素投入量和固定要素投入量之间的比例在发生变化，在可变要素投入的最初阶段，相对于固定要素来说，可变要素的比例过少，因此，随着可变要素的连续投入，其边际产量递增。
当可变要素与固定要素的投入量达到某一个特定的最佳的数量组合比例时，可变要素的边际产量达到最大。
如果继续增加可变要素的投入，可变要素与固定要素之间的比例就会越来越偏离这个特定值，可变要素的比例过多，于是边际产量减少。
在任何产品的短期生产中，随着可变要素的连续投入，他的边际产量必然出现递减的特征。
即边际产量递增之后必然出现边际产量递减。
生产要素投入的最佳组合生产要素投入的最佳组合既包括成本不变条件下的最大产量和产量不变条件下的最小成本，这两者表现在图形上都是等产量曲线与等成本线的切点，即生产者的均衡点。
1．既定成本下的产量最大化（图加解释）2．既定产量下的成本最小化（图加解释）能满足要素投入量最佳组合的两个条件是1．最佳组合的均衡点都在等成本曲线上，如果在等成本曲线外，是不肯能达到的组合，如果在等成本曲线呢，则说明企业没有完全利用资金，使资金闲置。
2．均衡点都是等成本线和等产量曲线的切点，这就意味着在该点两条曲线的斜率相等，即两要素的边际技术替代率等于两要素的价格之比。
规模报酬规律当企业从一个很小的规模逐渐扩大时，厂商首先面临的是规模报酬递增阶段，当企业得到了生产规模扩大的全部好处时，一般会继续扩大生产规模，将生产保持在生产规模不变的阶段，这个阶段可能比较长，在这个阶段以后，如果企业继续扩大生产规模，就会进入规模报酬递减阶段。
说明规模报酬递增与规模经济的关系规模报酬递增是指厂商产量的增加的比例大于生产要素投入增加的比例，设生产函数Q=F （L,K）如果Q(ML,MK)大于MQ(L,K)，其实M大于0,则我们称该生产函数具有规模报酬递增的性质。
微观经济学试题及答案英文版
微观经济学试题及答案英文版Microeconomics Exam Questions and Answers (English Version)Question 1:Define the law of demand and explain how it relates to the concept of elasticity.Answer 1:The law of demand states that, all else being equal, the quantity demanded of a good or service will decrease as its price increases, and vice versa. Elasticity, specifically price elasticity of demand, measures the responsiveness of the quantity demanded to a change in price. It is calculated as the percentage change in quantity demanded divided by the percentage change in price. If the absolute value of the elasticity coefficient is greater than one, the demand is elastic; if it is less than one, the demand is inelastic; and if it equals one, the demand is unit elastic.Question 2:Explain the concept of marginal utility and how it relates to consumer behavior.Answer 2:Marginal utility is the additional satisfaction or utility derived from consuming one more unit of a good or service. It is the first derivative of the total utility function with respect to the quantity consumed. As consumers consume moreof a good, the marginal utility typically decreases, a phenomenon known as the law of diminishing marginal utility. This concept is fundamental to understanding consumer behavior and the decision-making process when allocating a limited budget among various goods and services.Question 3:What is the difference between a perfectly competitive market and a monopoly?Answer 3:A perfectly competitive market is characterized by a large number of buyers and sellers, homogeneous products, free entry and exit, and the absence of barriers to entry. Prices are determined by the market and individual firms are price takers. In contrast, a monopoly is a market structure where there is only one seller of a unique product with no close substitutes. The monopolist has market power and can set prices above marginal cost, leading to deadweight loss and inefficiency.Question 4:Explain the concept of opportunity cost and give an example.Answer 4:Opportunity cost is the value of the next best alternative that is forgone when making a choice. It represents the benefits an individual, investor, or business misses out on when choosing one alternative over another. For example, if a farmer has a choice between growing wheat or corn on a piece of land, the opportunity cost of choosing to grow wheat isthe profit that could have been earned from growing corn.Question 5:What are the factors that determine the shape of a firm's supply curve?Answer 5:The shape of a firm's supply curve is determined by the relationship between the cost of production and the quantity supplied. If the marginal cost of production is constant, the supply curve will be perfectly elastic (horizontal). If the marginal cost increases as production increases, the supply curve will be upward sloping. Factors such as technology, input costs, and the availability of resources can influence the shape of the supply curve.End of ExamPlease note that this is a sample exam and the questions and answers provided are for illustrative purposes only.。

提出有关经济学的问题
提出有关经济学的问题1.什么是经济学？经济学是一门研究如何有效分配有限资源的社会科学。
它涉及生产、分配和消费商品和服务的过程，以及与这些过程相关的决策制定、行为和效果分析。
经济学可以帮助我们理解个体、家庭、企业和国家在面临稀缺资源时的选择和行为。
2.什么是经济体系？经济体系是一个国家或地区内资源分配和生产活动的组织框架。
主要的经济体系包括市场经济、计划经济和混合经济。
市场经济主要由市场力量决定资源分配和生产活动，计划经济则由政府计划和控制资源分配和生产活动，混合经济则是两者的结合。
3.供给与需求模型如何解释市场价格和数量的决定？供给与需求模型解释了市场价格和数量的决定。
需求曲线表示消费者对商品或服务的需求量，供给曲线表示生产者提供的商品或服务的供给量。
通过需求和供给的交互作用，市场价格和数量在均衡时得到决定。
当需求增加或供给减少时，价格上涨，数量增加；当需求减少或供给增加时，价格下跌，数量减少。
4.什么是机会成本？机会成本是指当作出某种选择时，所放弃的最佳替代方案的成本。
经济学认为，由于资源有限，所以当我们做一个选择时，就意味着我们必须牺牲其他选择。
机会成本帮助我们衡量我们的选择是否是有效的，以及是否值得。
5.什么是边际效益？边际效益是指从增加或减少一单位某种行动的结果中获得的额外效益。
在经济学中，我们使用边际概念来帮助分析决策。
当边际效益大于边际成本时，我们会做出某种决策；当边际效益小于边际成本时，我们可能会选择其他方案。
6.什么是GDP？GDP（国内生产总值）是衡量一个国家或地区经济活动总量的一个指标。
它代表了一个特定时间段内，一个国家或地区在商品和服务生产方面的总值。
GDP是一个重要的经济指标，被用于衡量经济增长、生活质量和国家竞争力。
7.外汇市场对经济有什么影响？外汇市场是全球各国货币交易的市场。
外汇市场的汇率决定了不同货币之间的兑换比例。
外汇市场的变动可以对一个国家的经济产生重大影响。
economicessayquestion7经济学基础
economicessayquestion7经济学基础Unit 7 Exam Essay Questions1) Discuss real and nominal GDP. Explain how they are similar and how they differ. Explain the challenge with using nominal GDP to measure the growth of the economy.Nominal GDP is GDP of current price of products during the year. Real GDP is corrected for changes in prices from year to year. Nominal GDP is measured in recent prices. The real GDP in gross domestic product expressed in prices adjusted for inflation. If only calculated the nominal GDP, you correct for inflation, the real GDP adjusts for increase for inflation because the price are changing for inflation not GDP increase.2) Describe the types of information economists use to forecast the business cycle and how they use this information to make predictions about the business cycle.First, economists focus on the stock market. When a recession occurs, the stock market will take a quick decease. Next they review the rates of interest to see if they are going up or down. When the interest rates are growing up, it means economy is in its expansion, and the government is trying to maintain stable growth.Another factor is looking at huge purchases made by companies. If companies purchase lots of money for expenditure, it is means economy looks good and businesses feel it will keep growing.3) Describe two types of unemployment and provide an original example of each.There are two typical kinds of unemployment called seasonal and cyclical. Take teachers for an example, during the summervacation or any other holidays, teachers do not have to work at school. That`s called seasonal. About cyclical, just as workers in the factory, when an economy recession occur, companies decide to reduce the production and ensure the interest, they will fire some workers, which called cyclical unemployment.4) Define Gross Domestic Product and explain the two approaches used to measure it. Provide original examples that represent both approaches.One is called expenditure approach it calculates by estimating the annual spent in 4 areas of products. For example, in a country, the consumption of the country is 3000. The investment is 6900. Government spent 4700 this year. And the net export is -1142. So the GDP is the sum of the consumption, investment, government spending and net export, which are 13,458.Another called income approach by just adding up all the income earned in the economy. For an instance, a company produces tools individuals used in school daily life just as notebooks, pens and papers. The notebook book sales person makes 500 per week, the pen sales man makes 300 per week and the paper sales guy makes 600 per week, so the GDP per week is 1400 using the income approach.5) Describe the four phases of the business cycle, and describe three situations that can happen during a contraction In the business cycle, when economy increases and GDP figures grow up, it called expansion. At the peak, there is no increasing on the economy and no change in real GDP. The contraction is a decrease in the economy after a expansion. After the contraction, we are having the trough which is the bottom of the business cycle. The GDP figures stops decreasing and theeconomy in the trough which is the lowest point at economy.During a contraction, there will be recession which means economy goes down for at least 6 month, depression that means the economy recession for a long time and stagflation which is the GDP goes down but price rise.6) Explain how the government calculates the unemployment rate. Give an original example to aid your explanation.Unemployment rate is the people looking for jobs divided by the total number of workers then times 100%. The people looking for work must be over 16 years old and trying to find jobs not like the university students who are focused on higher education. For example, in one country, all numbers of workers is 300,000 and 16,400 of them are looking for jobs. So the unemployment rate is 16,400/300,000*100%=5.5%.7) Define the term inflation and explain how it is used as a measure of economic performance. Use an original example that shows how prices might rise over time to aid your explanation.Inflation is an increase in prices and reducing purchasing power of money. When inflation occurs, the value of dollar is decreasing; interest rates increase and real return and savings are reducing.When the inflation occurs, people will spend less to buy productions. Government will spend less and increase the interest rates to pull money back of the circulation.For example, 10 years ago, using 3￥can by 6 ice creams, but now we only can have 3 for the same price. So the price is increasing but we are getting the same thing this is caused by inflation。
