LSE例题答案+解析

Answers and Explanations

1、Macro

1. B

Explanation: A multinational company (MNC) is defined as a firm that owns or controls production or service facilities in more than one country.

2. D

Explanation: The supercomputer belongs to physical capital can boost the UK’s economy.

3. A

Explanation: Amount spent in yen = 6,300,000 X ¥175.16 = 1,103,508,000 yen.

4. D

Explanation: Direct taxes are taxes that are levied directly on individuals or organizations and are paid directly to the government (income tax and corporation tax).

5. A

Explanation: Elasticity of supply refers to how responsive the quantity supplied is to changes in price. If supply is elastic (greater than 1), it means that producers can easily increase the quantity supplied in response to price changes (such as from subsidies).

......

2、Micro

1. A

Explanation: Opportunity cost is the next best alternative foregone. By leaving her job, Margaret gives up her bank salary.

2. C

Explanation: Merger is two independent firms combine to form a single business.

3. D

Explanation: Variable costs increase as output rises. Since total costs include variable costs, total costs also increase when output rises. Fixed costs do not change. Marginal costs typically decrease initially as output increases, due to economies of scale.

4. D

Explanation:

2024 productivity = 605 ÷ 506,180 ≈ ¥1.195 million per employee.

2025 productivity = 775 ÷ 508,180 ≈ ¥1.525 million per employee.

Change = 1.525 ÷ 1.195 - 1 ≈ 28% increase.

5. D

Explanation: In monopolistic competition, many firms sell differentiated products with some degree of brand distinction. Each has limited pricing power, since substitutes exist.

......

3、Quantitative

1. B

Explanation: In a simple linear regression, the line always passes through the mean of both variables. So given the mean of X, the mean of Y, and the intercept a, you can find the slope b using:

2. C

Explanation: The total possible outcomes are 36, The favourable outcomes include: A = 2, B = 1; A = 3, B = 1,2; A = 4, B = 1,2,3; A = 5, B = 1,2,3,4; A = 6, B = 1,2,3,4,5. Thus, the probability that A > B = (1+2+3+4+5)/36 = 42%.

3. A

Explanation: Since there are equal numbers of red and blue balls (6 each out of 12 total). The draws are independent because the selection is with replacement. To get balls of different colors, two cases are possible: Red first, then blue, or blue first, then red. Therefore, the probability of getting one red and one blue ball (in any order) is (0.5 x 0.5) * 2 = 0.5.

4. D

5. A

Explanation: In statistics, a complete statistic is one that contains all possible information about a population parameter. However, for it to be useful in estimation, it must also be sufficient — meaning it captures all information about the parameter contained in the sample data.

2025剑桥圣凯瑟琳学院经济学营精彩回顾

Economic Academic camp -St Catharine's college,cambridge

剑桥圣凯瑟琳学院2025年（7.19-7.29）经济学营精彩回顾

剑桥大学圣凯瑟琳学院St Catharine's College,cambridge成立于 1473 年，位于剑桥市中心毗邻著名的国王学院。因其在参观国王学院大教堂的必经之路上，所以每个去剑桥旅游的人，一定都会经过它。学院以其卓越的学术成就、悠久的历史和现代化的设施吸引了全球顶尖学生，同学们亲切地给它起名为“Catz”。

我们先来听听教授和同学们的真实反馈吧!

“So l think i'm actually honestly very impressed with thestudents because as l said, we prepared materials that aresupposed to give them exposure toeconomics at Cambridge,and they are still much younger than undergraduate students that we get here. But the quality of the interventions, the questions that l get, the answers that l get when l propose a question to students were really impressive. So l think, and it's a very nice selection of students.”说实话，我真的对这些学生印象非常深刻。正如我之前提到的，我们准备的材料是为了让他们接触剑桥的经济学内容，而他们的年龄还远小于我们这边本科生的年龄。但他们的发言质量、提问水平，以及我向他们提问时收到的回答都非常令人惊艳。我认为这是一个非常优秀的学生群体。

--剑桥大学，Dr Pablo Olmos

“在这次学术营中学到了很多新的东西，比如以前没深入接触过的预算约束线(Budget Line)、无差异曲线(IndifferenceCurve)等。并且我还深刻意识到了经济学与数学密不可分的关系，之前我学习的时候没有实感，这次来剑桥发现老师们上课会用很多数学公式才真正理解了数理分析的重要性。最有趣的体验是Workshop环节，我们小组化身经济体，亲自设定储蓄率(Saving Rate)和对技术、教育的投资率(Investment Rate)，直观地看到这些决策如何动态影响经济发展，把抽象公式变成了活生生的过程…这次经历让我亲身体验了剑桥的教学模式和教授思维，不仅更坚定了我申请剑桥的决心，也帮我精准定位了自身差距，为未来一年的准备和可能的面试打下了宝贵基础。”

--北京大学附属中学，白同学

“我之前就想来欧洲体验一下，感受一下这边的文化，这次来剑桥期待都满足了。最大的收获是上课:剑桥老师讲得特别细，一步一步拆开讲，虽然我之前学过一点经济，但是比较笼统，这次不仅从底层逻辑开始了解，还分析各种模型，感觉对经济学理解深了很多。课堂气氛也很好，老师特别鼓励我们提问发言，没啥作业压力，反而让我更喜欢经济了。另外，领队老师们人都超级好，很照顾我们，有什么问题都能帮忙。还能遇到好多厉害的同学，因为能来这儿的都有点本事嘛。总的来说，课程安排合理，老师牛，领队负责，同学优秀，我觉得特别值得推荐给其他同学!”

--佛山美伦国际高中，龚同学

“这次能来剑桥参加经济学营特别开心!剑桥大学是我心仪的学校，经济学也是我热爱的专业，所以接到电话通知时就很惊喜!上课收获真的很大，Pablos教授和RiverChen教授讲的微观经济学、宏观经济学、统计分析等内容都让我耳目一新，尤其是索洛模型、刘易斯模型这些之前很少接触的知识，感觉打开了新世界的大门。最大的改变是发现经济学根本不是我想象中的“文科”，它需要很强的数学思维，比如算成本函数、生产函数还要用偏导，这和我学的A-Level很不一样，感觉对学科的理解完全颠覆了。”

-上实剑桥外国语中学(浦西校区)，唐同学

“这次收获挺大的，虽然课程对我来说有点难(我才高一，学的是大一内容，教授讲得也快)，但内容超出了我的预期。不光讲了我学过的，还接触了经济发展这些新东西，特别有意思的是像今天那样扮演企业家、计算公司GDP的实践活动。还有这次出来也体验了海外学习的不同:首先肯定是语言环境不同了;其次英国这边的饭嘛..哈哈。不过上完课回头看看自己以前学的东西，感觉简单多了，对以后考试也更有信心了!”

--西南大学附中国际课程中心，王同学
