RMIT University ECON1010 Assignment 2: Macroeconomic Principles

This assignment solution for ECON1010, a macroeconomics course at RMIT University, addresses key macroeconomic concepts. The assignment covers topics including the monetary system, inflation, and aggregate demand and supply (AD-AS) using the AD-AS framework. The solution includes T-accounts to illustrate the effects of reserve ratios on the money supply, an analysis of how a credit squeeze impacts the real economy, and an evaluation of the effects of unexpected inflation on various economic actors, such as the government, homeowners, and pensioners. Furthermore, it provides an explanation of Milton Friedman's statement on inflation and discusses the relevance of macroeconomic indicators in the real world, using the example of developing countries' economic challenges. The solution demonstrates an understanding of the interconnectedness of macroeconomic variables such as GDP, inflation, and unemployment, and their impact on the overall health of an economy.

Macro1 (ECON1010), Sem. 2 2017 Question Set
Short Answer Questions:
1. Consider an economy in which initially there are no banks. Suppose that one consumer initially holds
the entire money supply in the form of $1,000 in currency. Then assume a new bank is opened, The
First National Bank, and the consumer deposits the entire $1,000 into the bank. Based on this
scenario answer the following questions (5 marks):
a. Assuming that the First National Bank has a 100% reserve ratio, use a T account to show what effect
this deposit will have. (0.5 mark)
First National Bank
Debit Credit
Reserves 1000
Deposits 1000
b. Still assuming a 100% reserve ratio, explain what effect this deposit will have on the economy’s total
money supply. (1 mark)
The deposit will negatively impact the money supply. This is because the consumer holds the entire
money supply which is now deposited in a bank. On the other hand, the bank will have sufficient
reserves.
c. Show how the First National Banks T account will look, if instead it has a 10% reserve ratio and
holds no excess reserves. (0.5 mark)
Minimum reserves = 1000 *10% = $100
Excess Reserves = 1000 -100 =$900
First National Bank
Debit Credit
Reserves 100
Deposits 1000
Loan 900

d. Following form c. if other banks now open up and face a 10% reserve ratio, and assuming that every
consumer holds her or his money as deposits instead of currency, explain what effect the initial
deposit will eventually have on the money supply. (1 mark)
In case other banks are able to open up and they get a 10% reserve ratio, they are therefore able to
give out loans from the excess reserves to the public. This money will be brought into the cycle
through lending and the banks will continue to have excess reserves. The result will be increase in
the money supply since the amount deposited is multiplied by a money multiplier.
= 1000 * 10 = 10000
= 10000 - 1000 = 9000
Money supply increases by 9000.
e. Are consumers as a group wealthier when the banking system chooses a 10% reserve ratio. Explain
the reasons for your answer. (2 marks)
In a sense the consumers become wealthier with a 10% reserve ratio, this is because a large amount of
the money is loaned out and is able to gain interest also, the borrowers are able to invest in businesses
that are able to gain a return which increases the wealth of the entire economy.
2. Using the AD-AS framework consider the following scenario. The economy is operating at full
employment when an unanticipated crisis hits the banking sector that results in a credit squeeze. (4
marks)
a. Explain in detail how this event in the financial system is likely to impact the real economy and what
will be the implications for unemployment and inflation in the short term. In your answer be sure to
also address which components of the AD-AS model may be impacted by this scenario. Your answer
should be around ½ page. (3 marks)
In case of a credit squeeze, the money supply is limited by the banks. This may mean that there is an
increase in the interest rates that make loanable funds less accessible to the borrowers who might require the
money not only to spend but also invest. In the short term therefore the aggregate demand may decrease
since there is reduced capacity to purchase. Due to the decrease in aggregate demand, the economy real
output decreases while the prices also decrease. The level of inflation decreases and the unemployment
levels increase due to reduced investment levels.

b. Using the diagram below, illustrate how this scenario will:
i) Influence equilibrium in the short run (SR) labelling the new SR equilibrium A. (0.5 mark)
ii) Influence equilibrium in the long run (LR) assuming no government or policy intervention
labelling the new LR equilibrium B. (0.5 mark)
Illustrate here (Tips: to create new lines, simply copy the existing curves and move to the new
locations)
3. Suppose that inflation in Australia was expected to be 3% in 2016, but that prices rose by 5%
instead. Would the unexpectedly high inflation help, hurt or have no effect on the following. After
identifying the effect that the higher than anticpated inflation has in each case, briefly explain the
reason why in one of two sentences for each case. (4 marks)
a. The federal government (1 mark)
Inflation reduces the real value of government debt especially since the taxable revenues also rise with
inflation. It therefore makes it easier for the government to pay its debts.
b. A homeowner with a fixed rate mortgage (1 mark)
The homeowner gains from inflation because since it is a fixed mortgage rate, the real money value is lower
than the cost of paying the debt.

c. A private school that has invested some of its endowment in government bonds (1 mark)
The private schools is protected and better off since the bonds retain its value and is not susceptible to the
fluctuating interest rates. Also it is able to gain more for the value at which it invested.
d. A pensioner whose pension has been indexed based on the forecasted anticipated rate of inflation. (1
mark)
The pensioner is a gainer of inflation since his income will match up with the levels of inflation thereby
retaining his purchasing power of his real income.
4. Milton Friedman states: ‘Inflation is always and everywhere a monetary phenomenon.’ In ¼ of a
page explain what he means by this statement. (2 marks)
According to Milton, inflation is as a result of money dynamics in the sense of money supply and demand.
For example, increase in money supply may lead to a demand pull inflation since there is increased
aggregate demand compared to the supply in the market which may in turn contribute to cost push inflation
as the suppliers increase their demand for factors of production (Mankiw, 2014).
5. Based on what you have studied so far in Macroeconomics1, discuss and describe something that
you have found interesting and insightful that helps you understand the relevance of
Macroeconomics to the real world. Answers should be between ½ a page and 1 page in length.
(Note: This is an open question in which students should provide a real world example and explain
how some part of the course has aided understanding relevant to the example provided.) (5 marks)
Macroeconomics provides insight concerning the Macroeconomic indicators and why the international
organizations take the GDP, inflation and unemployment statistics to high consideration. It is because they
are interrelated and that they have an effect on the health of the economy as a whole. For example the
developing countries are often faced with high levels of unemployment while at the same time battling
inflation mostly because their governments often incur budget deficits which they finance through incurring
of debts in currencies which are quite expensive and overall increases their debt burden (Burda ad Wyplosz
2013).
