Economics Principles Assignment: Inflation, GDP, and Demand Analysis

This economics assignment solution addresses key concepts in microeconomics and macroeconomics. The assignment covers the calculation of inflation rates, the impact of unemployment benefits on national income, and the effects of various economic events on the Consumer Price Index (CPI) and Gross Domestic Product (GDP). It explores how changes in consumer confidence and domestic prices influence aggregate demand, and how slower income growth in other countries affects demand. Furthermore, the solution provides insights into economic contractions, the business cycle, and the role of GDP in measuring national output. The assignment utilizes economic models and principles to analyze real-world scenarios, providing a comprehensive understanding of economic concepts.

Task 6
Answer 1)
As unemployment benefits are not included
while calculating the national income , it can be
therefore said the unemployment benefits of $500
per annum will not be calculated while measuring
the national income. Therefore, it can be said that
there will be no change in his national income.
Answer2)
The rate of inflation is 21.7%
The rate of inflation is calculated by the formula:

Answer 5)
When a used textbook from a friend is used, the transactions will not add to the value
of gross domestic product since the GDP only includes the final value of the newly produced
goods. Therefore, it can be said that buying an old or an used textbook will not add to the
gross domestic product.
Answer 6)

4ECONOMICS PRINCIPLES
As it is known the newly produced goods are calculated in the gross domestic
product, so it can be said that when a publisher buys a new printing machine in order to print
new textbooks, the transactions will be included in the GDP(Baumol and Blinder 2015).. As
only on the final goods, the GDP can be calculated, buying the new printing machine will add
to the value pf the domestic product.
Answer 7)
The consumer price index is a type of economic indicator which measures the price
movements of a basket of goods and services. The CPI usually rises within a short period of
time in case of inflation. Cyclone Larry resulted in the increase in CPI as the price of bananas
increased after cyclone. As the cyclone have destroyed the crops, the price of bananas have
increased (McConnell, Brue and Flynn 2014). The impact is definitely an overestimation of
CPI and inflation as the basket of goods which were used for calculating CPI might be facing
a much more high rate of interest. Therefore, it can be said that the impact of the cyclone is
an overestimation of the consumer price index.
Task 7
Answer1)
When there is reduction in the consumer confidence there is a tendency of the
consumer to spend less money and save more. Consumer confidence is a type of economic
indicator which states the optimistic degree of a consumer about the overall state of the

5ECONOMICS PRINCIPLES
economy. The confidence of any consumer generally increases when the economy usually
expands and goes down when the economy contracts. Investors, retailers, banks and
government agencies use various assessments of consumer confidence for making future
plans.
When there is a rise in the confidence of the consumer, he will spend more and
therefore the aggregate demand curve shifts to right. On the other hand when there is a
decrease in the confidence of the consumer, the aggregate demand will shift to left as at that
time the consumer will spend less and save more (Microeconomics, E.E., 2015). Therefore,
when there is reduction in the confidence of the consumer, the aggregate demand will shift to
left.

6ECONOMICS PRINCIPLES
Answer 2)
When there is an increase in the domestic price, the aggregate demand curve shifts
left. When the price increases people will demand less. As the interest rate also rises,
consumers tend to demand less amount of good. Therefore, it can be said when prices
increases, there is a decrease in demand.
Answer3)
Aggregate demand will shift to the right when there is slower income growth in other
countries. In this case the demand of the particular country increases as in the other countries
there is a lower growth of income. Therefore, it can be said when there is slower growth of
income in other countries, demand curve will shift to right.
Answer4)
The decrease in the national output which is generally measured with the help of gross
domestic product is termed as economic inflation. Therefore, being an advisor of the federal
government, an individual need to look at the value of the gross domestic product of the
economy.
An economic contraction is a kind of phase in the business cycle where the economy
is in decline. A contraction is also said to form when the real gross domestic product of a
country has decreased in case of two or more consecutive years. the rate of unemployment
also increases in the period of economic recession. Economic contraction also results to the
fall in real personal income and the sales of the retail (Baumol and Blinder 2015). Companies
also stops hiring people in order to save money. In the period of economic contraction

7ECONOMICS PRINCIPLES
companies usually starts laying off workers and also sends the rates of unemployment on a
higher scale. A contraction also results due to loss in confidence which will also slow
demand. The business cycle is composed of four kinds of discrete phases which are
expansion, contraction, peak and trough. The peak phase states the end of the expansionary
period after which the rate of contraction takes place. In case of contraction the investors also
sells stocks and they also sends the prices downward by reducing financing in case of large
corporations.
