AP考试真题解析(宏观、微观经济学FR部分)
AP宏观经济学考试题型分析
AP宏观经济学考试题型分析准备考AP宏观经济的同学看过来，下面小马整理的是AP宏观经济学的考试题型分析，供大家参考，祝大家都能取得优异成绩。
ap考试宏观经济学的考试分为多项选择题和自由回答题两种题型，其中多项选择题是60道题，用时70分钟;自由回答题是3道大题，其中第一道大题平均有5-6道小题，用时大概25分钟，第二道和第三道大题平均有3-4道小题，用时分别为12.5分钟。
其中多项选择题部分占学生考试得分的2/3，自由回答题部分占余下的1/3。
多项选择题主要考察的是学生对宏观经济学基础知识的把握程度，考点主要是基本宏观经济学概念、宏观经济学概念的扩展、宏观经济学的应用以及各个概念的对比分析等。
自由回答题主要考察的是学生对宏观经济学基本框架的把握和理解，以及对宏观经济学分析工具的应用能力，其中的一部分问题需要进行图形分析，要求考生对宏观经济学中图形分析工具具有相当程度的掌握。
AP宏观经济学的考点分析AP宏观经济学的考点大致分为：国民经济核算体系，国民收入的决定--收入和支出模型，货币、利率和国民收入，宏观经济政策，国民收入的决定：总供给---总需求模型，失业与自然失业率，通货膨胀理论，开放经济下的宏观经济理论，经济增长理论，经济周期，西方经济学主要学派。
其中考察的重点知识为国民经济核算指标，菲利普斯曲线，失业和通货膨胀，开放经济下的宏观经济学，财政和货币政策，银行和货币创造等。
AP宏观经济学的备考策略首先，AP宏观经济学考试最重要的备考方法还是从基础的经济学知识角度掌握整个宏观经济学的分析框架以及分析思路，从而可以从本质上抓住考试的重点。
其次，AP经济学考试不同于GRE，TOEFL或SAT等英文考试，经济学是一门学科，侧重的是知识性和内容性，因此技巧对于AP考试来说就不是最重要的因素，从而考生在复习考试的时候要淡化技巧，强调知识学习。
最后，AP宏观经济学考试要求考生培养一种经济学素养，可以从经济学视角解释和说明现实中的很多问题。

AP微观经济模拟题二答案AnswersandExplanations
AP微观经济模拟题⼆答案AnswersandExplanations Answers and Explanations1.E—Know the four scarce economic resources.2.D—A concave PPF exhibits the Law of Increasing Costs. As more ofa good is produced, opportunity costs rise. This is becauseresources are not perfectly substitutable between the production of different goods.3.E—Demand is more elastic if there are more substitute goods. Amonopolist has no close substitutes so is likely the least elastic demand.4.A—Nation A has comparative advantage in crab production and NationB has comparative advantage in cake production. Nation Aspecializes in crabs, Nation B specializes in cakes, so avoid any option suggesting the opposite. Choice A is the only one that allows both to consume beyond the PPF.5.B—Nations that invest in research and technology expect the PPFto expand; the key to economic growth.6.B—Rational decision makers consume right up to the point where theMB of the next cookie is exactly equal to the MC of the next cookie.7.B—Tea is a coffee substitute. Higher tea prices increase coffeedemand.8.C—Leftward demand shifts, coupled with rightward supply shifts putdownward pressure on prices.9.B—Price ceilings are legal maximum prices set below theequilibrium price. A shortage results.10.A—The more narrowly a good is defined, the more elastic demand.11.C—Private property is fundamental to the free market economy.12.E—The supply curve is more elastic as more time elapses.13.D—If the demand curve is more inelastic (more vertical) a greaterburden of an excise tax falls upon consumers and less uponproducers.14.C—The opportunity cost of starting a small store is the salarygiven up in the next best alternative for the entrepreneur's skills.15.A—A price floor is a legal minimum price set above the equilibriumprice. Higher coffee prices decrease the demand for complementary goods like coffee machines.16.E—P * MP L = MRP L..17.B—At the second worker, wage = MRPL18.E—In perfect competition, short-run profits may be positive ornegative, or normal, but long-run profits are always normal.19.D—This is the equilibrium price.20.C—When the price falls and quantity demanded rises, consumerspending on the good (P * Q) can change in two directions. If E d >0, a percent decrease in price increases quantity demanded by a greater percent, increasing spending on the good.21.D—PS is the area under the price and above supply.22.A—Substitution and income effects explain the Law of Demand.23.D—Using the utility maximizing rule, set MU c/$1 = MU s/$4. There arethree options where the MU c is four times the MU s, and only one of those options uses exactly $20 of daily income.24.A—The Gini coefficient measures income inequality. The closer itgets to one, the more unequal the income distribution. Oneexplanation for inequality is more market power in product and input markets. This redistributes CS to monopoly producers and/oremployers.25.B—Quickly look at the graph to eliminate some possibilities. Withdollars on the y axis, this curve cannot represent TPL (output on the y axis) or total utility (utility on the y axis). The other key is that this curve has a value of zero dollars at an output of zero.TC = TFC at zero output and short-run economic losses equal TFC at zero output.26.C—If the price of eggs rises, demand for bacon falls if they arecomplementary; E xy < 0.27.D—Labor is a variable cost so there is no change in TFC, but anincrease in TVC and TC.28.E—This defines diminishing marginal returns and is often missed, rather by students, who make the mistake of identifying falling TPL than falling MP, with diminishing returns.L29.A—Know the characteristics of all market structures.than the worker 30.E—The 4th worker is the first to have lower MPLbefore.31.C—Constant returns exist when a larger firm has constant LRAC.32.E—All other choices would produce a decrease in the demand for goodX and would therefore decrease both the price and quantity. You are looking for the only choice that would NOT. More consumers for good X would increase demand and increase both the price and quantity 33.E—Since you know that AVC is$25 at Q = 10, TVC is $250. Addingthis to the given $100 of TFC produces $350 of total cost at Q =10.34.A—The vertical distance between TC and TVC is TFC.curve. Higher labor productivity 35.A—Demand for labor is the MRPLincreases labor demand.36.D—AFC declines as output rises.37.C—The shutdown point is at P < AVC.38.A—With no externality, MSB = MSC. With a negative externality MSC >MPC = MSB for the good.39.B—Barriers to entry are a defining characteristic of monopoly.40.B—Economies of scale are a common barrier to entry; a key tomaintaining long-run positive profits.41.A—Find the output level where MR = MC and locate the price fromthe demand curve. Profit is equal to Q * (P–ATC) at that output.42.C—CS is the area above price and under demand.43.C—A four-firm concentration ratio is the sum of the market shareof the four largest firms in an industry.44.D—Utility-maximizing consumers do not equate the units of twogoods, they equate MU/P for each good.45.D—As industries approach monopoly, prices rise, lowering CS.46.E—Negative externalities, like "fowl" odors, impose spillovercosts upon third parties. These costs, ignored by the market, reflect an over-allocation of resources to chicken production.47.B—Know the characteristics of all market structures.48.A—Product differentiation results in a small degree ofprice-setting ability, and downward sloping demand curves for the firms. P = ATC and profits are normal in the long run, this output level does not occur where ATC is minimized. This defines excess capacity.49.B—DWL emerges when output is moved away from where P = MC.50.C—If P = ATC, economic profit is zero, or normal.51.D—Allowing more foreign competition lessens market power of amonopolist and improves efficiency as the price falls closer to MC.52.E—Semitrucks are a complementary resource to the truck drivers.If the price falls, demand for the labor rises.53.C—The monopsony hiring decision.54.C—Use the least-cost rule of MPL /$5 = MPK/$10 to find the optimalcombination of labor and capital. There are three combinations oflabor and capital where the MPK is twice the MPLbut only one choiceproduces 18 units of output. Remember that adding the marginal products provides the total product.55.B—This describes a cartel.56.A—Certification exams decrease labor supply and raise the wage inthe market. A higher wage increases the MC of producing the good, which raises the price of the good.57.E—If the price of a substitute resource falls, labor demand canincrease if the output effect is greater than the substitution effect.58.D—Know your public goods.59.B—You are the recipient of a spillover benefit from your neighbor'spurchase of a pool.60.D—The private marketplace underprovides for a public good becausefree riders benefit from the good without paying for it. Government must provide the public good.Free-Response Grading RubricNote:Based on my experience, these point allocations roughly approximate the weighting on similar questions on the AP examinations. Be aware that every year the point allocations differ and partial credit is awarded differently.Question 1 (12 points)Part (A): 2 pointsThese points are graphing points. A perfect response shows the salmon supply curve shifting to the left, increasing the price, and decreasing equilibrium quantity in the market. These prices and quantities must be labeled.Part (B): 5 pointsThis part of the question asks you to explain something, which means a graph is not required. However, a graph may assist your explanations.1 point: Explain that higher salmon prices increase the demand for tuna,a substitute.i. 1 point: The higher demand for tuna increases the price of tuna. ii. 1 point: Increased demand increases the market quantity.iii. 1 point: Charlie increases his production as the price rises. iv. 1 point: The price is now above average total cost so Charlie's economic profit is greater than zero.Part (C): 5 points1 point: Because positive economic profits were being made in part (B), firms enter the tuna fishing industry.i. 1 point: The higher supply for tuna decreases the price of tuna. ii. 1 point: Increased supply increases the market quantity. iii. 1 point: Charlie decreases his production as the price falls. iv. 1 point: In the long run P = ATC so Charlie's economic profit is equal to zero. You can also say that he earns normal profits.Question: OK, so what if I screwed up part (B)? Am I doomed in part (C)?Answer: Maybe not, but you cannot bank your hopes for a 5 on generous partial credit.Suppose in part (B) (iv), that you said Charlie would suffer economic losses because the price is below ATC. This is incorrect and so the last point in part (B) cannot be given.But … and here is where the partial credit may differ from year to year. If in part (C) you correctly described the long-run adjustment to losses, you may (and I stress may) receive some or all of the five points in part C.Part (C): alternative scoring to an incorrect presumption of losses in part (B)1 point: Because negative economic losses were being made in part (B), firms exit the tuna fishing industry.i. 1 point: The lessened supply for tuna increases the price of tuna. ii. 1 point: Decreased supply decreases the market quantity.iii. 1 point: Charlie increases his production as the price rises. iv. 1 point: In the long run P = ATC so Charlie's economic profit is equal to zero. You can also say that he earns normal profits.Question 2 (7 points)Part (A): 5 pointsThese are all graphing points so to get all five points, all curves, axes, and directional shifts must be perfectly identified.1 point: A correctly labeled graph showing the supply curve shifting upward by the amount of a tax.i. 1 point: Showing that the price increases after the tax.ii. 1 point: Showing that the quantity decreases after the tax.iii. 1 point: Tax revenue is the area of the rectangle yP2DW.iv. 1 point: Dead weight loss is the area of the triangle DWL shown above.TIP: In a question like this, there are very little partial credit possibilities. You either get the graphing points or you do not. Part (B): 2 points1 point: Consumer spending increases.1 point: Because the percent increase in the price is greater than the percent decrease in quantity. It is also accurate to refer to proportional changes.TIP: The last point is the more difficult of the two and serves to differentiate students. In the past you might have also received credit for saying "a large increase in the price outweighs a small decrease in quantity." It is much more accurate to refer to proportional or percentage changes and in future years the rubric might be more stringent on this point.Question 3: (7 points)Part (A): 2 pointsThese are points for just being able to read the payoff matrix in this game. Since we know that Firm 1 is choosing Costly Ads, then you must focuson the top half of the matrix. If Firm 2 is choosing Cheap Ads, then the game ends in the top right square.i. 1 point: $250ii. 1 point: $75Part (B): 2 pointsThe key here is obviously to know what it means to have a dominant strategy.A dominant strategy is one that is always superior to the other option, no matter what the rival firm is doing. For example, if Firm 2 plays Costly Ads, Firm 1 should do the same because $100 (Costly Ads) beats $75 (Cheap Ads). If Firm 2 were to play Cheap Ads, Firm 1 would play Costly Ads because $250 (Costly Ads) beats $200 (Cheap Ads). So Firm 1 would always play Costly Ads. The same is true of Firm 2.i. 1 point: Yes, playing Costly Ads is a dominant strategy for bothfirms.ii. 1 point: Because, no matter what the rival firm is doing, this strategy always beats Cheap Ads.Part (C): 1 pointThe outcome is that both firms earn $100 because, without collusion, both will play the dominant strategy, Costly Ads.Part (D): 2 pointsA prisoners' dilemma is a situation where playing the dominant strategy produces an outcome that, in hindsight, could have been better for both if the firms could have colluded and coordinated their strategies.1 point: Yes, it is an example of a prisoners' dilemma.1 point: Both firms could have improved profits ($200 each vs. $100 each) by colluding with a selection of Cheap Ads.

2019年AP宏观经济学真题解析【第一题】
2019年AP宏观经济学真题解析【第一题】【分析】这个题继2016年考察了菲利普斯曲线之后，又再一次考察了这个知识点。
历年较常考的总需求和总供给曲线也有涉及。
同样涉及的还有财政政策和外汇市场。
题目条件中给出了X国经济的失业率和通胀率数据。
自然失业率为5%，实际失业率为7%，通胀率为5%。
从实际失业率高于自然失业率这个条件中，我们可得知X国当前处于recession经济衰退时期。
【考点】Short run & long run Philips Curveaggregate demand and short run aggregate supply curveFiscal policyForeign exchange marketDeterminants of exchange rate【答案】(a)2016年FR第一题a问出现了不太常规的考点Philipscurve(菲利普斯曲线)之后,2017年又一次在第一题a问中考察了这个考点。
菲利普斯曲线展示的是失业率和通胀率之间的关系，横轴为unemployment rate失业率,纵轴为inflation rate通胀率。
短期菲利普斯曲线(SRPC)展示了失业率和通胀率之间负相关的关系，而长期菲利普斯曲线(LRPC)则是一条垂直的直线，对应的失业率为自然失业率。
因为当前X国处于经济衰退时期，实际失业率7%高于自然失业率5%。
短期均衡点B应该位于长期菲利普斯曲线右边，对应7%的失业率和3%的通胀率。
如图所示(b)(i) 如果政府不采取任何措施干预，长期经济能够自动调回到充分就业的状态。
原因是人们的通胀预期降低。
当经济处于衰退时期，物价长期处于低迷水平，人们会逐渐调整对工资的预期，接受更低的工资。
所以公司成本下降，总供给增加。
SRAS短期总供给曲线会右移回到长期均衡。
另一方面，因为短期总供给增加，会导致更低的通胀率和更低失业率。
所以若是反映在菲利普斯曲线上，在长期，短期菲利普斯曲线会左移。

AP拯救计划第四弹！微观经济PK宏观经济？资料免费领！
AP拯救计划第四弹！微观经济PK宏观经济？资料免费领！在美国，经济学的地位很高，如同在中国人人都会学习政治一样，经济学是美国学生的必修课程。
到了大学，金融、工商管理、市场营销、公共管理等专业都需要一定的经济学知识，因此预备本科留学美国的国际生们也越来越多开始学习经济学。
有人说，经济学很枯燥、很抽象，果真如此吗？经济学教授薛兆丰在综艺《奇葩说》里看起来严肃呆板，格格不入，但总能活用经济学知识，把节目里的辩题解释得既通透易懂，又接地气，杀出一片人气。
他让棕榈君知道，其实经济学渗透在生活的方方面面，它很具象，也可以很有趣。
比如当他讨论“什么样的工作，更可能996？”时，引用了经济学里“相对价值”的概念。
他是这样解释这个概念的：做饺子的时候，面粉多了，肉就贵；男孩多的地方，女孩贵；资本密集的地方，劳动力的价值高。
由于资源搭配，那些“资本多、变化大、机会特别多”的工作岗位愿意付给“劳动力时间”的费用更高，人们也就更愿意多付时间去工作，更愿意996。
经济学是一门实用的学问，是研究关于个人、机构和社会在资源稀缺的背景下如何做出最佳选择的学科。
由于资源有限，我们要利用已有的资源办最多的事情，要学会合理分配资源。
经济学要教给我们的即是如何合理使用、分配有限资源。
薛兆丰在他的著作《经济学通识》写道：用什么样的眼光，就有什么样的世界。
用经济学的眼光，说不定能看见另一个精彩纷呈的世界。
AP经济学考试经济学是一门文理科生都适合学习的学科，AP经济学考试则是一个零基础起步、拿五分难度也不大的考试。
AP微观经济和宏观经济，同微积分、统计学一起，为中国最早引进的4门AP课程，也是中国学生报考人数较多的AP科目。
2019年AP微观经济学全球五分率22.2%、四分率28.4%，2019年AP宏观经济学五分率17.6%、四分率22.9%，两门都属于在AP考试中较容易获得高分的科目，是中国学生的热门选择。
那么报考AP经济学，是选择微观经济还是宏观经济呢？我们先来看一下两者的区别。

ap考试真题解析（宏观。
微观经济学fr部分）教学文稿2015 年AP 考试真题解析（宏观经济学FR 部分）AP 宏观经济学的FR 题目每年都是三道题，其中第一题问到的内容也相对较多，所占比重比较高，总分30 分的简答题中，第一题占到了将近一半的分值。
AP宏观经济学的FR真题每年涉及的知识点大同小异，包括AD-AS、菲利普斯曲线、货币市场、可贷资金市场、外汇市场等模型，同时会涉及到财政政策、货币政策和国际贸易等政策性内容。
“年AP宏观经济学考试涉及的考点还是基本沿袭了之前的风格，AD-AS 模型、可贷资金市场、货币市场、外汇市场都有所涉及，重要的图形中唯一没有考到的是菲利普斯曲线，财政政策和货币政策也都考到了，相对冷门的考点是第二题中的国际贸易。
另外，三道题中都可以看出每一小问之间的连带性，很多时候某一问做错了，后面连续就都做错了，这也是让考生们头疼的地方。
大家在2016 年的AP 宏观经济学考试中，一定要特别注意这种题目之间的连带性，每问得出结论是都要格外仔细。

ap考试真题解析
2015年AP考试真题解析(宏观经济学FR部分)AP宏观经济学的FR题目每年都是三道题，其中第一题问到的内容也相对较多，所占比重比较高，总分30分的简答题中，第一题占到了将近一半的分值。
AP宏观经济学的FR真题每年涉及的知识点大同小异，包括AD-AS、菲利普斯曲线、货币市场、可贷资金市场、外汇市场等模型，同时会涉及到财政政策、货币政策和国际贸易等政策性内容。
“2015年AP宏观经济学考试涉及的考点还是基本沿袭了之前的风格，AD-AS模型、可贷资金市场、货币市场、外汇市场都有所涉及，重要的图形中唯一没有考到的是菲利普斯曲线，财政政策和货币政策也都考到了，相对冷门的考点是第二题中的国际贸易。
另外，三道题中都可以看出每一小问之间的连带性，很多时候某一问做错了，后面连续就都做错了，这也是让考生们头疼的地方。
大家在2016年的AP宏观经济学考试中，一定要特别注意这种题目之间的连带性，每问得出结论是都要格外仔细。
第一题这是一道非常非常典型的AP宏观经济学FR第一题，涉及到了一个国家的运行以及如何使用政策改变现在的运行状态。
第一问：几乎每年都会让考生用AD-AS模型画出一个国家的运行状态。
题目中说到美国的经济正运行在充分就业以下，说明国家正处在衰退状态，这时在AD-AS模型中，我们要把长期AS曲线画在短期AS与AD曲线交点的右方，如下图：*注意横纵轴要写实际GDP和价格水平，短期均衡点对应Y1，而长期AS对应Yf第二问：说到美联储想要让经济回到充分就业，也就是经济不要继续衰退，那么它应该使用扩张型的货币政策，让利率下降，从而使得投资增加，达到扩张经济的效果。
（这里要强调的是，题目中提到的federal funds rate是指美国商业银行间的同业借贷利率，在题目中如果没有特意提到这个意思，考生们只要理解成美国最基准的利率就可以了。
所以在这道题中，只要回答应该以低的federal funds rate为目标就可以了。

ap微观经济考试内容
ap微观经济考试内容
ap微观经济学考试的内容主要有生产可能性曲线、供求关系、通货膨胀、经济系统等基础经济学知识。
ap微观经济学的内容主要包括基本经济概念、产品市场的性质和功能、要素市场、市场失灵与政府作用。
ap微观经济学主要以单个经济单位（ 单个的生产者、单个的消费者、单个市场的经济活动）作为研究对象，分析单个生产者如何将有限的资源分配在各种商品的生产上以取得最大的利润。
材料补充：
宏观经济学和微观经济学的区别：
1、研究对象不同：微观经济学的研究对象是单个经济单位，如家庭、厂商等。
宏观经济学的研究对象则是整个经济，研究整个经济的运行方式与规律，从总量上分析经济问题。
2、解决的问题不同：微观经济学要解决的是资源配置问题。
即生产什么、如何生产和为谁生产的问题，以实现个体效益的最大化。
宏观经济学则把资源配置作为既定的前提，研究社会范围内的资源利用问题，以实现社会福利的最大化。
3、研究方法不同：微观经济学的研究方法是个量分析。
即研究经济变量的单项数值如何决定。
而宏观经济学的研究方法则是总量分析，即对能够反映整个经济运行情况的经济变量的决定、变动及其相互关系进行分析。
这些总量包括两类，一类是个量的总和，另一类是平均量。
因此，宏观经济学又称为总量经济学。

AP 宏观经济 考试纲要 MacroEcon topic outline
Students should be able to use the aggregate demand and aggregate supply model to determine equilibrium income and price level and to analyze the impact of economic fluctuations on the economy's output and price level, both in the short run and in the long run.
I. Basic Economic Concepts
A macroeconomics course introduces students to fundamental economic concepts such as scarcity and opportunity costs. Students understand the distinction between absolute and comparative advantage and apply the principle of comparative advantage to determine the basis on which mutually advantageous trade can take place between individuals and/or countries and to identify comparative advantage from differences in opportunity costs. Other basic concepts that are explored include the functions performed by an economic system and the way the tools of supply and demand are used to analyze the workings of a free market economy. The course should also introduce the concept of the business cycle to give students an overview of economic fluctuations and to highlight the dynamics of unemployment, inflation, and economic growth. Coverage of these concepts provides students with the foundation for a thorough understanding of macroeconomic concepts and issues.
历年AP统计学真题解析及答案
历年AP统计学真题解析及答案AP统计学考试有选择题和简答题两种类型，相对于选择题来说，简答题的难点在于根据实验目的，明确实验步骤，注重实验细节，并用英文表述出来。
因为可以使用计算器，因此计算的部分一般不是难点，但解答过程又不能直接写出使用计算器得出的数字结果，还要分步骤写出计算过程。
考点：1.用box plot展示两组数据的分布；2.计算数据的特征值，从而做出统计决策。
分析：a.两个箱线图的分布中，集中程度的指标（采用中位数）是近似一样的，离散程度的指标（极差和四分位差）是有区别的。
注意对异常值的描述。
在这个问题中，不用描述数据分布的信息（即判断分布是对称、左偏或有偏），因为箱线图并不能直观展示这一特征。
b.A比B好在值比较大，B比A好在最小值比较大。
（答题过程中要注意上下文的背景信息。
）参考答案：往年考题中也有很多对比描述的问题，如2011-B-1、2012-3、2013-6（对用histogram、line graph展示的两组数据进行比较）。
考点：1.用置信区间进行总体比例的假设检验；2.在做总体比例的区间估计时，样本量和边际误差之间的关系。
分析：a.通过一个样本值，估计出总体比例的置信区间为（0.09,0.21），包含给定的总体值0.2，故不能拒绝这一总体值；b.样本量变大4倍时，抽样分布的标准差变小为原来的1/√（4），边际误差也变为原来的一半。
写出边际误差的计算公式即可看出数量关系。
c.边际误差变小后，置信区间变小，不再包含给定的总体值，只能拒绝这一总体值。
参考答案：考点：1.离散型随机变量的概率分布；2.离散型随机变量概率分布的期望值；3.条件概率；4.给定变量值下的期望值。
分析：a.给定离散型随机变量的概率分布，事件的并，用加法；b.给定离散型随机变量的概率分布，计算期望值；c.条件概率的计算；d.样本空间变化后，得到新的离散型随机变量的概率分布，计算期望值。
参考答案：考点：两个总体比例差的假设检验分析：实验目的：检验服用低剂量的阿司匹林是否能减低患大肠癌的几率；实验思路：1000个人随机分成两组，分别进行两个处理（服用低剂量的阿司匹林、服用安慰剂），测试患病的比例，比较两个比例的差值，从而验证低剂量的阿司匹林能够降低患病的几率。

2015年AP考试真题解析(宏观经济学FR部分)AP宏观经济学的FR题目每年都是三道题，其中第一题问到的内容也相对较多，所占比重比较高，总分30分的简答题中，第一题占到了将近一半的分值。
AP宏观经济学的FR真题每年涉及的知识点大同小异，包括AD-AS、菲利普斯曲线、货币市场、可贷资金市场、外汇市场等模型，同时会涉及到财政政策、货币政策和国际贸易等政策性内容。
“2015年AP宏观经济学考试涉及的考点还是基本沿袭了之前的风格，AD-AS模型、可贷资金市场、货币市场、外汇市场都有所涉及，重要的图形中唯一没有考到的是菲利普斯曲线，财政政策和货币政策也都考到了，相对冷门的考点是第二题中的国际贸易。
另外，三道题中都可以看出每一小问之间的连带性，很多时候某一问做错了，后面连续就都做错了，这也是让考生们头疼的地方。
大家在2016年的AP宏观经济学考试中，一定要特别注意这种题目之间的连带性，每问得出结论是都要格外仔细。
第一题这是一道非常非常典型的AP宏观经济学FR第一题，涉及到了一个国家的运行以及如何使用政策改变现在的运行状态。
第一问：几乎每年都会让考生用AD-AS模型画出一个国家的运行状态。
题目中说到美国的经济正运行在充分就业以下，说明国家正处在衰退状态，这时在AD-AS模型中，我们要把长期AS曲线画在短期AS与AD曲线交点的右方，如下图：*注意横纵轴要写实际GDP和价格水平，短期均衡点对应Y1，而长期AS对应Yf第二问：说到美联储想要让经济回到充分就业，也就是经济不要继续衰退，那么它应该使用扩张型的货币政策，让利率下降，从而使得投资增加，达到扩张经济的效果。
（这里要强调的是，题目中提到的federal funds rate是指美国商业银行间的同业借贷利率，在题目中如果没有特意提到这个意思，考生们只要理解成美国最基准的利率就可以了。
所以在这道题中，只要回答应该以低的federal funds rate 为目标就可以了。
）第三问：就是把第二问细化，CB很喜欢这种出题方式。
我们从第二问中已经知道美联储应该使用扩张型的货币政策，也就是要增加货币供给，才能使得名义利率降低，所以只要在货币市场的图像中画出MS曲线的右移使得利率降低就可以了，如下图：*注意横轴纵轴的坐标，一般货币市场的纵轴我们要用名义利率，不要写实际利率。
两个箭头也要标出来说明是MS右移了，利率下降了。
第四问：考查财政政策了，这也是惯用的出题方式，财政政策和货币政策穿插着考。
题目中告诉我们边际消费倾向(MPC)是0.8，并且要弥补的衰退缺口是300 billions，第1小问问到需要多少政府支出能够弥补衰退缺口，显然是在考查乘数。
乘数的公式是1/(1-MPC)，在本题中的乘数就是5。
也就是说政府支出的变化会对GDP产生5倍的放大效果，所以只需要60billions 的政府支出就能弥补300billions的衰退缺口。
第2小问问到如果改成通过调整税收的财政政策来弥补衰退缺口，那么税收的变化和之前的政府支出变化哪个更大。
这问就涉及到税收乘数和支出乘数的比较问题，税收乘数等于-MPC/(1-MPC)，不仅是个负值，由于MPC<1，它的绝对值也要比政府支出乘数小，所以要想弥补同样水平的衰退缺口，税收的改变量需要更大。
第五问：问到减少衰退缺口的税收变化如何影响总需求和长期总供给。
从第四问我们知道，税收的GDP是反向关系，所以问了扩张经济，税收应该减少，这样会增加人们的可支配收入，从而刺激消费，是的总需求增加。
而一般我们认为能够影响长期总供给曲线的应该是资源以及科技方面的投入性因素，税收改变的消费和总需求，对于长期总供给曲线没有影响。
第二题考查了国际贸易，涉及机会成本、绝对优势以及相对优势的概念，这个考点以前在FR题中出的次数比较少，不过赶上这个考点的学生其实是赚到了，因为这类问题绝大多数情况下不难。
第一问：问到哪个国家在生产solar panel上有对绝对优势。
绝对优势概念比较简单，就是使用同样的资源，哪个国家生产的产品多哪个国家就在这个产品上有绝对优势。
从题目中的数据可以看出，明显是Y国家生产solar panel的数量要更多一些，所以国家Y在生产solar panel上有绝对优势。
第二问：要我们计算国家Y生产一个furnace的机会成本，也就是计算生产一个furnace需要放弃的solar panel的数量。
使用同样的资源，国家Y可以生产6个furnace或者12个solar panel，也就是说多生产1个furnace要放弃12/6=2个solar panel，即国家Y生产一个furnace的机会成本是两个solar panel。
第三问：哪个国家在生产furnace上有比较优势。
比较优势是指一国在生产某商品上的机会成本低于另外一国，所以判断比较优势需要我们计算每个国家生产商品的机会成本。
第二问中我们已经计算出国家Y生产furnace的机会成本是两个solar panel，而国家X可以生产6个furnace或者8个solar panel，生产一个furnace的机会成本是8/6=4/3个solar panel，这个数字显然低于国家Y，所以国家X在生产furnace上有比较优势。
第四问：是本题相对比较难的一问，问到了如果国际贸易中要求两个furnace交换一个solar panel，那么国家X应该进口solar panel还是自己生产。
很多考生可能都知道，国际贸易中，每个国家应该专业化生产自己有比较优势的产品，然后与其他国家通过贸易来获得其他的商品，这样大家都可以获益。
从第三问中我们可以看出，国家X在furnace上有比较优势，所以应该专业生产furnace，再进口solar panel。
这中分析方式当然没有问题，但是各位要注意，在这道题中规定了交换的比例，两个furnace交换一个solar panel，如果国家X本国生产solar panel，那么多生产一个solar panel需要放弃6/8=3/4个furnace，但是如果进行国际贸易，交换到一个solar panel却需要放弃两个furnace，这个数字比自己生产的成本数字还要高，也就是说按照题目中的比例进行交换还不如自己生产。
这道题告诉我们，在考虑能否从贸易中获利时，不仅要考查比较成本，还要看一下交换的比例。
第三题考查利率和汇率这两个核心概念，涉及到这两个变量的模型可能包括可贷资金市场、货币市场以及外汇市场，这三个图是大家一定要熟悉的。
第一问：说到日本政府的财政赤字会如何影响利率和投资。
这是常见的考法了，需要大家知道只要问到政府行为对于实际利率的影响，一定要用可贷资金市场来进行解释。
政府赤字说明政府储蓄减少，而储蓄对应的是可贷资金的供给，所以可贷资金供给减少，供给曲线左移，是的均衡的实际利率上升，这里在解释时考生们也可以画一个图，当然语言解释也是可以接受的。
而随着利率的上升，私人投资的数量肯定会下降，实际上是变相考查了所谓的挤出效应。
第二问：也是常见问法，在确定利率变化的基础之上判断外汇市场中出现的变化。
日本的利率升高，这说明日本的金融资产价值会增加，也就是说欧洲人在日本的投资收益会增加，所以欧洲人会愿意拿出更多的欧元兑换日元从而增加在日本的投资。
从欧元市场来看，欧元的供给会增加，从而导致欧元的日元价值，也就是欧元兑换日元的汇率下降，如下图：在画图时要注意纵轴的汇率要写成yen/euro这样的形式，这是AP宏观经济学的规定写法，用日元来衡量欧元的价值。
供给曲线右移以及汇率下降要画箭头来表示。
最后一问：问到如果欧盟的中央银行不愿意欧元贬值，它们是应该在外汇市场上购买还是卖出欧元。
在第二问中，因为欧元的供给增加导致欧元贬值，逆转这种变化的方式自然就是减少欧元的供给，所以中央银行应该购买欧元把外汇市场上的欧元回收，从而减小供给，供给曲线左移，汇率又会升高。
从这道题中我们可以看出，分析汇率变化的时候无论因素为何，最后一定要落脚到外汇市场的供给和需求的分析上，有些学生只是记住了一些因素对汇率会产生何种影响，但是却没有理解影响的机制，选择题可能还能应付，但是简答题就难说了。

题干中首先提到完全竞争市场是成本不边行业，而且厂商正在获得经济利润，这些条件大家做题的时候一定要注意，很有可能会在后面的题目中起到重要的作用。
1.第一问问到市场价格和厂商价格之间的关系，由于在完全竞争市场中，厂商是价格接受者，所以每个厂商的几个和市场供需关系决定的价格是完全一致的，非常简单的一个小问。
第二问就要画图了，这个就要用到我们在题干中看到的内容了。
题干中说到这个厂商正在获得正的经济利润。
所以我们在画图的时候要注意，厂商的价格水平要高于平均总成本呢，如下图：左边的图是市场的供需关系图像，右边的图则是厂商的图像，首先要注意市场的价格和厂商的价格水平要相等，MR=MC的点对应了Qf和Pf，保证利润最大化，MC曲线一定要穿过ATC的最低点，总成本就是ATC*Qf所对应的矩形区域的面积，最后就是D或者说MR曲线一定要在ATC的上方。
第三问问到如果一个厂商提升了价格，它的总收入会有什么样的变化。
我们知道对于完全竞争市场中的厂商来说，它们是价格接受者，所以消费者对它们的需求是完全弹性的，一旦提升价格，无论提升多少，需求量马上就会降为零，此时收入自然也会降低为零。
第四问提到如果现在现在整个完全竞争市场处于长期均衡，这个时候厂商的利润为零，厂商的图形中D和ATC应该正好切于ATC的最低点。
这些内容应该在读到题干的时候就要想到。
当然，这道题的重点在后面，题干中提到政府给了厂商lump-sum subsidy，也就是总额补贴。
这里要说明的一点就是lump-sum和per-unit，也就是总额和单位的区别。
如果政府收单位税或者给单位补贴，这样厂商的边际成本、平均可变成本以及平均总成本都会发生变化，但如果政府收总额税或者给总额补贴，那么厂商的边际成本和平均可变成本是不会变化的，只有平均总成本会发生变化。
在这道题中，第一小问问到厂商在短期生产的数量的变化，我们知道数量是由MR=MC这个利润最大化的条件来决定的，而由于只是总额补贴，MR 和MC都不会发生变化，那么利润最大化对应的生产数量就不会发生变化。
第二小问问到长期市场的价格和数量的变化，刚才提到过，虽然总额补贴不会影响边际成本，但是会影响平均总成本，补贴的发放使得厂商的平均总成本降低，ATC曲线下移，使得本来和ATC相等的价格高于ATC，也就是厂商在短期会获得利润。
