宏观经济学是经济学方向的重要课程之一,很多同学经常在作业中遇到一些问题。下面我们分享一些比较典型的作业题目和答案,对于这方面内容掌握不是特别到位的同学,可以利用下面这些题目多加练习。
一、经典例题
1.The demand curve and supply curve for one-year discount bonds with a face value of $1,000 are represented by the following equations:
Bd : price = -0.8 * Quantity + 1100
Bs : price = Quantity + 680
a. What is the expected equilibrium price and quantity
of bonds in this market?
b. Given your answer to part (a),what is the expected
interest rate in this market?
答案解析:
p=−0.8Q+1100,
p=Q+680;
-0.8Q+1100=Q+680,−0.8Q+1100=Q+680,
1.8Q=420,1.8Q=420,
Q=233,Q=233,
p=913.p=913.
2.From statistical studies,we know that for 1981 the supply curve for wheat was approximately as follows: Supply: QS = 1800 + 240p Where price is measured in dollars per bushel and quantities are in millions of bushels per year. These studies also indicate that in 1981 the demand curve for wheat was Demand: QD = 3550 – 266p a. Find the market clearing price and equilibrium quantity of wheat for the year1981. b. What do we mean by surplus and deficit? Show us your answer graphically using the above demand and supply functions c. Show the effects of changes in demand and supply in equilibrium price and equilibrium quantity
答案解析:
Qs=1800+240p,
Qd=3550-266p,
Qs=Qd,
1800+240p=3550-266p,
506p=1750,
p=3.46,
Qs=Qd=2630.
二、宏观经济学作业难点分析
1.作业涉及很多理论
这是很多学生刚开始接触经济学遇到的第一个问题。教授讲课时,可能没有太多时间来详细解释每一个理论,但是课本上又可能会有很多深奥的解释,这就给同学们造成了很大的学习难题。
2.图表理解起来困难
图表一般是用于说明经济概念和理论的,但是,往往涉及到图表类的作业题目,都是让同学们感觉最难的问题之一。就拿供给和需求举例,大部分同学可能根本不清楚曲线该在什么时候和什么地方移动,均衡嘉禾和数量是什么也不知道,我们面对的是什么类型的市场都不了解。这些都是导致大家觉得课程作业太难的关键因素。
对于课程作业问题的解决,最好的方式是多加练习,多思考。对于宏观经济学的诸多概念,要追求理解记忆。有不懂的问题,需要及时求助。如果需要补课,大家也可以随时联系留求艺,我们有专业的老师可以为大家提供1V1作业补习!
