Fundamentals of Macroeconomics
Week 2 Assignment
ECO/372
Macro Economics is a study which is concerned with the
economy as a whole and the level of total output which is also
referred to as national income is a very important variable in
any economy. National income measures the value of an output
produced in an economy over a period of time and the policy
makers should be aware of the level of economic activity taking
place within the country on behalf of the nationals.
One of the most important objectives of the government is to
increase the level of the rate of economic growth which is
possible only be measuring the national income. The main uses
of the national income statistics are:
1. It shows the current allocation of resources,
2. It helps the government in economic planning,
3. It helps measures the country’s standard of living, and
4. It helps in the comparison of the living standard between
different countries.
There are some important concepts of National Income such as
Gross Domestic Product, Gross National product, net National
product and The GDP per capita.
Gross domestic product: “GDP is the total value of all output
produced using resources located within the economy over a
given period of time”. It refers to the market value of all final
goods and services produced within a country in a given period
(O'Sullivan, Arthur).
GDP measures the annual value of all economic activity taking
place within the economy and the GDP measures are on a value
added basis in order to avoid the problem of double counting.
There are three ways of calculating the GDP but the results of
all the three methods should be the same. They are:
· The Output Method.
· The Income Method.
· The Expenditure Method.
Nominal GDP: Also known as the money GDP is measured in
terms of the prices operating in the year in which the output is
produced. it is sometimes referred to as GDP at market prices. It
can give a wrong impression about the performance of the
economy, because of the changes in the value of money which
depends on the price level, which is subject to changes.
Normally the Nominal GDP converted into Real GDp which is a
measure of adjustment for inflation is used to calculate the
National performance. Real GDP therefore is: money GDP/ the
price index of the current year X Price index of the base year or
money GDP/ GDP deflator of the current year X Price index of
the base year (HM Treasury, Background information on GDP
and GDP deflator).
Unemployment rate: Employment is the total number of people
with a job which includes the employees, businessmen and self
employed people. The number employed may change over time
due to many factors. While unemployment refers to those people
who have registered, able, available and willing to work at the
going wage rate at any suitable job but cannot find employment.
Unemployment is measured at a point of time and the level of
unemployment changes over time.
The number unemployed refers to the number of people of
working age, who are without job but are available for work at
the current wage rates. While the rate of unemployment refers
to those working age, who are without job, but are available for
work at current wage rates is expressed as percentage of the
total labor force.
Unemployment Rate = Unemployed X 100
Labor Force
Inflation Rate: Inflation is defined as the persistent or sustained
risein general price level. It is the change in the average prices
in an economy over a given period of time. The price level is
measured in the form of index. For example, if the price index
is 100 today and 110 in the next year, then the rate of inflation
would be 10%.
In economics, the “inflation rate is a measure of inflation, the
rate of increase of a price index and it is the percentage rate of
change in price level over time” (Sullivan, Arthur; Steven M.
Sheffrin (2003).
It can be calculated as:
Inflation rate = P0 – P -1 X 100 P-1
Interest rate: An interest rate is the rate at which the borrower
pays interest for the use of the lender’s money. For instance a
borrower uses the money belonging to a lender in his business
and in return he pays interest at a predetermined rate of interest
for deferring the use of funds and instead lending it to the
borrower. Interest rates are normally expressed as a percentage
of the principal for a period of one year (Mankiw, N. Gregory
(2009-04-18). The interest rates targets are a very important
tool in the monetary policy and are considered as vital in the
calculation and dealing with the variables like investment,
inflation and unemployment. They are a very crucial part of
macro economics. They are calculated as:
r = 1 + i -1
1+ p
The aforesaid economic variables are very important tools of
Macro Economics and are used in the calculation of the rate of
economic activities and economic growth in an economy over a
period of time.
Purchasing groceries is an activity which involves purchase and
sale at a price level. It creates demand for the groceries at a
price which covers the cost of production including wages. If
we take a two sector model of economy, it has the Household
and the business. The household owns the wealth of nation
including land, labor, capital used in the production of goods
and services, while the business or the firms produce goods and
services by hiring the factors owned by the households. The
households receive payments for hiring their factors, which they
spend on the purchase of groceries from the firms. This
generates output which contributes to the GDP, as the additional
output adds to the total output in the current year depending on
the withdrawals and injections into the economy.
When the economy faces a massive lay off of employees, it
directly affects the employment and income, which reduces the
aggregate demand bringing down the price level discouraging
further investment in business. This situation deteriorates the
production adversely affecting the GDP in that particular year.
This condition continues to prevail unless remedial measures in
terms of monetary and fiscal policies are taken.
When the government decreases the taxation rate, it increases
the consumption increasing the demand and price, which
induces the investors to invest more bringing up the level of
economic activities. Employment will also go up raising the
income level, which would further increase the aggregate
demand. A decrease in taxation therefore causes a rise in the
aggregate demand which would increase the employment,
income and other economic activities in an economy. If it
exceeds the limit it may also result in inflation.

Running head Fundamentals of Macroeconomics 1Fundamentals.docx

  • 1. Running head: Fundamentals of Macroeconomics 1 Fundamentals of Macroeconomics 2 Fundamentals of Macroeconomics Week 2 Assignment ECO/372 Macro Economics is a study which is concerned with the economy as a whole and the level of total output which is also referred to as national income is a very important variable in any economy. National income measures the value of an output produced in an economy over a period of time and the policy makers should be aware of the level of economic activity taking place within the country on behalf of the nationals. One of the most important objectives of the government is to increase the level of the rate of economic growth which is possible only be measuring the national income. The main uses of the national income statistics are: 1. It shows the current allocation of resources, 2. It helps the government in economic planning, 3. It helps measures the country’s standard of living, and 4. It helps in the comparison of the living standard between different countries. There are some important concepts of National Income such as Gross Domestic Product, Gross National product, net National product and The GDP per capita.
  • 2. Gross domestic product: “GDP is the total value of all output produced using resources located within the economy over a given period of time”. It refers to the market value of all final goods and services produced within a country in a given period (O'Sullivan, Arthur). GDP measures the annual value of all economic activity taking place within the economy and the GDP measures are on a value added basis in order to avoid the problem of double counting. There are three ways of calculating the GDP but the results of all the three methods should be the same. They are: · The Output Method. · The Income Method. · The Expenditure Method. Nominal GDP: Also known as the money GDP is measured in terms of the prices operating in the year in which the output is produced. it is sometimes referred to as GDP at market prices. It can give a wrong impression about the performance of the economy, because of the changes in the value of money which depends on the price level, which is subject to changes. Normally the Nominal GDP converted into Real GDp which is a measure of adjustment for inflation is used to calculate the National performance. Real GDP therefore is: money GDP/ the price index of the current year X Price index of the base year or money GDP/ GDP deflator of the current year X Price index of the base year (HM Treasury, Background information on GDP and GDP deflator). Unemployment rate: Employment is the total number of people with a job which includes the employees, businessmen and self employed people. The number employed may change over time due to many factors. While unemployment refers to those people who have registered, able, available and willing to work at the going wage rate at any suitable job but cannot find employment.
  • 3. Unemployment is measured at a point of time and the level of unemployment changes over time. The number unemployed refers to the number of people of working age, who are without job but are available for work at the current wage rates. While the rate of unemployment refers to those working age, who are without job, but are available for work at current wage rates is expressed as percentage of the total labor force. Unemployment Rate = Unemployed X 100 Labor Force Inflation Rate: Inflation is defined as the persistent or sustained risein general price level. It is the change in the average prices in an economy over a given period of time. The price level is measured in the form of index. For example, if the price index is 100 today and 110 in the next year, then the rate of inflation would be 10%. In economics, the “inflation rate is a measure of inflation, the rate of increase of a price index and it is the percentage rate of change in price level over time” (Sullivan, Arthur; Steven M. Sheffrin (2003). It can be calculated as: Inflation rate = P0 – P -1 X 100 P-1 Interest rate: An interest rate is the rate at which the borrower pays interest for the use of the lender’s money. For instance a borrower uses the money belonging to a lender in his business and in return he pays interest at a predetermined rate of interest for deferring the use of funds and instead lending it to the borrower. Interest rates are normally expressed as a percentage
  • 4. of the principal for a period of one year (Mankiw, N. Gregory (2009-04-18). The interest rates targets are a very important tool in the monetary policy and are considered as vital in the calculation and dealing with the variables like investment, inflation and unemployment. They are a very crucial part of macro economics. They are calculated as: r = 1 + i -1 1+ p The aforesaid economic variables are very important tools of Macro Economics and are used in the calculation of the rate of economic activities and economic growth in an economy over a period of time. Purchasing groceries is an activity which involves purchase and sale at a price level. It creates demand for the groceries at a price which covers the cost of production including wages. If we take a two sector model of economy, it has the Household and the business. The household owns the wealth of nation including land, labor, capital used in the production of goods and services, while the business or the firms produce goods and services by hiring the factors owned by the households. The households receive payments for hiring their factors, which they spend on the purchase of groceries from the firms. This generates output which contributes to the GDP, as the additional output adds to the total output in the current year depending on the withdrawals and injections into the economy. When the economy faces a massive lay off of employees, it directly affects the employment and income, which reduces the aggregate demand bringing down the price level discouraging
  • 5. further investment in business. This situation deteriorates the production adversely affecting the GDP in that particular year. This condition continues to prevail unless remedial measures in terms of monetary and fiscal policies are taken. When the government decreases the taxation rate, it increases the consumption increasing the demand and price, which induces the investors to invest more bringing up the level of economic activities. Employment will also go up raising the income level, which would further increase the aggregate demand. A decrease in taxation therefore causes a rise in the aggregate demand which would increase the employment, income and other economic activities in an economy. If it exceeds the limit it may also result in inflation. Reference: · World Bank, Statistical Manual >> National Accounts >> GDP–final output, retrieved January 2012.
