In Ghana, prices of goods and services like food, clothes and transport keep rising over a period of time. What is this situation called?
Strand 4 · Government Economic Policy and Trade
Economics Year 2 Learner Material, Section 8: Macroeconomics Variables
In this section, you will discover how changes in key macroeconomic variables such as gross domestic product, inflation, unemployment, and interest rates, can affect the Ghanaian economy and other countries. For instance, rising inflation might reduce consumer purchasing power (the ability to afford goods and services), leading to higher costs for consumers. Similarly, higher unemployment can result in lower national output, as fewer people are working and producing goods and services. This reduction in output can impact the overall economic growth and tax revenues of a country.
You will also learn about control policies, like fiscal and monetary policies, that the government uses to manage and stabilise the effects of the macroeconomic variables in the economy. Additionally, you will discover how to calculate National Income using the three main approaches: the income approach, the expenditure approach, and the product approach. Finally, you will understand the uses and importance of National Income, such as measuring the standard of living, guiding government or banking policy decisions, and tracking economic growth.
KEY IDEAS
• An increase in inflation reduces purchasing power, meaning people can buy less with the same amount of money, leading to higher costs for goods and services. High unemployment reduces the economy’s total output, as fewer people are working and producing goods and services.
• Changes in macroeconomic variables, such as GDP (Gross Domestic Product- the total value of all goods and services produced within a country’s borders), inflation (the rate at which prices for goods and services rise), unemployment (the percentage of the labour force that is jobless and actively seeking work), and interest rates (the cost of borrowing money), can significantly affect the economy Ghana. These changes influence factors like consumer spending, business investment, and overall economic growth.
• Governments can use fiscal policies (like changing tax rates or government spending) and monetary policies (like adjusting interest rates or the money supply) to control the effects of macroeconomic changes.
• National income can be calculated using three different approaches: the income approach (summing all incomes earned), the expenditure approach (adding all spending in the economy), and the product approach (calculating the total value of goods and services produced).
• National income is an important indicator of a country’s economic health. It reflects the GDP, the total value of goods and services created within the economy over a specific period, typically a year.
• National income helps measure the standard of living (the average wealth, comfort, and material goods available to a person or community), track economic growth (the increase in the amount of goods and services produced per head of the population over a period), and guide government policy decisions aimed at improving citizens’ welfare.
In any country, the economy is constantly changing. Macroeconomic variables significantly influence how well the economy performs. Gross Domestic Product (GDP) measures the total value of all goods and services produced within a country over a specific period, usually a year. Changes in GDP directly impact the economy by indicating whether it is growing or shrinking.
a. When GDP increases, it generally signifies more jobs and higher living standards.
b. When GDP decreases, it can result in higher unemployment and economic difficulties.
At this level, you will focus on how changes in inflation, unemployment, and exchange rates affect GDP:
Inflation: A sustained increase in the general price level of goods and services, which can reduce consumer purchasing power and affect economic stability.
Deflation: Deflation is the general decline in prices for goods and services across an economy.
Unemployment: The percentage of the labour force that is jobless and actively seeking work, which can lower total economic output and consumer spending.
Exchange Rate: The value of one currency in terms of another, which can influence international trade, imports, and exports.
Understanding these relationships will help you grasp how various factors interplay to influence a country’s economic health.
Inflation Inflation is when prices of goods and services, like food, clothes, and transportation, increase over time. In Ghana, just like in any country, inflation can affect how much the economy grows or shrinks, which is shown by changes in GDP (Gross Domestic Product).
1. When inflation is low and stable, people and businesses can plan better because they know prices will not change too much. This helps the economy grow because people have more money to spend, businesses can make more products, and overall, GDP increases.
2. When inflation is high, prices increase rapidly, making things more expensive.
If people cannot afford to buy as much, businesses sell fewer products, and the economy may slow down. As a result, GDP could decrease because people are spending less, and businesses are producing less.
In Ghana, if inflation gets too high, it can make life harder for people because their money does not go as far. But if inflation stays under control, it can help the economy grow and make life better for everyone.
Figure 8.1: Image depicting Inflation
Table 8.1: Effects of inflation on an economy Positive Effects of Inflation Negative Effects of Inflation It encourages Spending and Investment:
When inflation is low, people may be more likely to spend and invest their money rather than to save it because they know prices might rise in the future. This can help businesses grow and create jobs, which is good for the economy.
It makes things more expensive: Inflation increases the cost of everyday goods and services like food, transportation, and housing.
This can be difficult for people in Ghana, especially those with lower incomes because their money cannot buy much as before.
It increases Wages: Inflation can lead to higher wages for workers, especially if businesses raise pay to keep up with higher prices.
It creates Uncertainty and Stress: High inflation makes it hard for people and businesses to predict future prices, leading to uncertainty, stress, and slower economic growth.
It helps Reduce Debt: Inflation can make it easier for people and the government to pay off debt. If prices and wages rise, the money borrowed in the past is worth less, so it becomes easier to repay loans or debts.
It reduces Savings: When inflation is high, the value of money decreases over time. This means that if people save money in a bank, it might lose its value as prices rise. So, saving money becomes less rewarding.
Business Profits Increase. For businesses, selling goods at higher prices can increase profits, and the money can be used to improve production processes or employ more people.
Businesses do not make as much money Rising costs of inputs can lead to higher production costs, which can reduce profitability and production if businesses cannot pass these costs onto consumers.
Activity 8.1 Understanding the Effect of Inflation on GDP Instructions In this activity, you will explore how changes in inflation can affect a country’s Gross Domestic Product (GDP) and how inflation impacts the economy.
1. Use the internet to find the inflation rates for Ghana in 2021, 2022, and 2023 from reliable sources such as the Ghana Statistical Service, national budgets, newspapers, the World Bank, and the IMF.
2. Record the inflation rate for each year (2021, 2022, and 2023).
3. Search for and record the GDP of Ghana for 2021, 2022, and 2023. This data can also be found on the Ghana Statistical Service website or from international sources like the World Bank or IMF.
4. Create two bar charts to COMPARE the inflation rate and GDP for Ghana in 2021, 2022, and 2023.
• Use the horizontal or x-axis for the year and start at 2020.
• Make sure each bar is the same thickness for each chart, 2cm would be fine.
• Choose your own scale for the y-axis for each chart and start at a number just below the data for 2021.
• Ensure your axes have equal divisions to maintain consistency and readability.
• Clearly label the x-axis with the years and the y-axis with the relevant units (percentage for inflation rate and currency units for GDP) Finally provide a title for each chart to clearly indicate what it represents (e.g., “Inflation Rate in Ghana (2021-2023)” and “GDP in Ghana (2021- 2023)”).
5. Compare the graphs for the years 2021, 2022, and 2023. Write the trends you will observe.
6. Answer the Following Questions:
a. How did the inflation rate in Ghana change from 2021 to 2023?
b. What happened to Ghana’s GDP in the same period? Did it increase, decrease, or stay the same?
c. Based on what you observed, how do you think inflation affected GDP in Ghana? Do higher inflation rates seem to reduce GDP, or does the relationship seem different?
d. Write two positive and two negative effects of inflation on the economy of Ghana.
e. How would you explain the effect of inflation on the economy to the people of Ghana?
f. What advice would you give to the government on controlling inflation to help the economy grow?
7. Prepare a report on your findings and present it to the class for discussion and feedback.
Unemployment Unemployment occurs when qualified people who want to work cannot find jobs. In Ghana, like in other countries, changes in the level of unemployment can have a great effect on the country’s economy and its Gross Domestic Product (GDP).
When unemployment is high, it means many people are not working. This can harm the economy because people will not have money to spend, and businesses will sell less. When businesses sell less, they may produce less, and the economy may shrink.
As a result, the GDP can decrease because fewer goods and services are being made and sold.
When unemployment is low, it means more people are working and earning money.
This is good for the economy because people can buy things, and businesses may produce more products. This can help the economy grow, leading to a rise in GDP.
Figure 8.2: Images depicting Unemployment Effects of Unemployment on the Economy
Table 8.2: Comparing the Negative and Positive Effects of Unemployment Negative Effects Positive Effects Reduced Consumption: Less income leads to decreased consumer spending and lower economic output.
Wage Adjustments: Labour surplus can lower wages. Reduced labour costs for businesses, improves competitiveness and profitability.
Lower Investment: High unemployment decreases business confidence and reduces investments in capital and innovation.
Resource Reallocation: Resources
(including labour) can shift to more productive sectors during economic downturns.
Lost Productivity: Represents a loss of productive potential in the economy, leading to decreased efficiency and growth potential.
Encourages Education and Skill
Development: Unemployment can push people to go back to school or learn new skills to improve their chances of getting a better job in the future.
Decreased Tax Revenues: Fewer people employed result in lower tax revenues, and this means the government has less to spend on health education and roads.
Increased Government Spending: Higher
spending on social safety nets to provide money for people who cannot afford basic essentials like food, strains public finances and leads to higher costs and debt.
Activity 8.2 Analysing Unemployment Statistics by Sector in Ghana Objective: To compare unemployment statistics by sector for 2022 and 2023 and create pie charts to visualise the data.
Data Provided
1. 2022 Unemployment by Sector in Ghana
• Agriculture: 5.2%
• Manufacturing: 7.5%
• Services: 10.3%
• Construction: 8.1%
• Other: 4.0%
2. 2023 Unemployment by Sector in Ghana
• Agriculture: 4.8%
• Manufacturing: 6.9%
• Services: 9.7%
• Construction: 7.5%
• Other: 3.5% Instructions
1. Analyse the Data in the following way
a. Compare the unemployment rates for each sector between 2022 and 2023.
b. Identify which sectors saw an increase or decrease in unemployment rates.
2. Create Pie Charts
a. Use the data to create two pie charts: one for 2022 and one for 2023.
b. Each pie chart should represent the distribution of unemployment by sector for that year. To draw your chart, you will have to convert each % to an angle by adding all the %s up to find a total then dividing each % by that total and multiplying by 100 to find the % for each sector of your pie chart. Round up your percentages to whole numbers.
c. Label the sectors and add a title to your charts.
3. Complete a written Comparative Analysis
a. Write a short paragraph comparing the unemployment rates by sector between the two years.
b. Discuss any trends or significant changes you observe with your friend or someone at home.
c. You should find that in 2023, the unemployment rate in Ghana decreased in all sectors compared to 2022. Compare this trend with the change in GDP in Ghana over the two years. Add your findings to your written analysis Exchange Rate The exchange rate is the value of a country’s currency (Ghana Cedi), compared to other currencies like the US Dollar or the Euro. Changes in the exchange rate can affect the economy of Ghana and its GDP (Gross Domestic Product) in different ways.
When the Ghana Cedi is strong (that is, it is worth more compared to other currencies), goods made in Ghana become more expensive for other countries to buy. This can reduce exports (products sold to other countries), which may hurt businesses in Ghana and lower GDP. On the other hand, imports (goods bought from other countries) become cheaper, which may increase the amount of goods Ghana buys from different countries.
When the Cedi is weak (that is, it is worth less compared to other currencies), goods made in Ghana become cheaper for other countries to buy. This can increase exports, which helps Ghana’s businesses grow and can lead to a rise in GDP. However, imports become more expensive, which might lead to higher prices for things like fuel, food, or other products that Ghana imports.
Figure 8.3: Image depicting Exchange Rate Effects of a Weak Currency on Exchange Rate (Exchange rate depreciation) Positive Effects Negative Effects Boosts Exports: A weak currency makes Ghana’s goods cheaper for other countries, so more people may want to buy products from Ghana, thus increasing exports.
Makes Imports More Expensive: A weak currency makes it more costly to buy things from other countries, such as fuel, food, and technology, leading to higher prices and inflation.
Increases Tourism: Foreign visitors can find it cheaper to travel to Ghana, which may bring in more tourists and help the economy to grow.
Uncertainty for Businesses: Weaker
exchange rates make it harder for businesses to plan and invest because they cannot calculate profits or pricing strategies.
Helps Local Businesses to Compete:
Ghanaian businesses can sell their products at lower prices abroad, making them more competitive in international markets.
Increases Debt: If the government or businesses borrow money in foreign currencies, they have to pay back more because the local currency is weaker, making debt difficult to repay.
Encourages Foreign Investment:
A weaker currency can attract foreign companies to invest in Ghana because it becomes cheaper for them to do business in the country.
Reduces the Standard of living: When prices of everyday goods go up due to a weak currency, it can make life harder for people, especially those with lower incomes, as they cannot afford as much.
Loss of Foreign Money: Investors
providing money for infrastructure projects or industrial development might move their money out of the country to avoid losses from as the currency gets weaker.
Effects of a Strong Currency on Exchange Rate (Exchange rate appreciation) Positive Effects Negative Effects Lower inflation: A strong currency keeps inflation down because it is cheaper for Ghana to buy imported goods and services from other countries, like fuel, food, and technology.
Reduces Export Competitiveness:
Domestic goods made in Ghana become more expensive abroad so countries buy then from somewhere else decreasing export volumes.
Increased Consumer Purchasing Power:
People and businesses have more money and can afford to buy more both at home and abroad.
Trade Deficit: If Ghana imports more than it exports this can lead to a trade deficit. This means that more money flows out of the country than comes in making the economy weaker.
Reduces cost of Foreign Debt repayments: If Ghana owes money in foreign currencies, a strong Cedi means it costs less to pay back those loans.
Slows Economic Growth: If there is less demand for products made in Ghana abroad, it can lead to a slower-growing economy, shown by lower GDP figures.
Improves Foreign Investment: A strong currency can make Ghana appear more stable to foreign investors, which can lead to more investment in businesses and infrastructure.
Increases Unemployment: cheaper imports put more pressure on businesses in Ghana and some may have to reduce their workforce, leading to higher unemployment.
Lower Production Costs: For businesses that rely on imported raw materials, a stronger currency reduces production costs, potentially increasing profitability.
Lower Tourism: Ghana becomes a more expensive destination for foreign tourists who may decide not to come and spend their money to boost the economy.
Activity 8.3 Effect of a Weak and Strong Currency on Ghanaian Economy Instructions This activity will help you to understand how changes in the exchange rate of the Ghanaian cedi to the US dollar can impact the economy.
1. Use the internet to search the exchange rate of the Ghanaian cedi (GHS) to the US dollar (USD) for the past three years (2019, 2020, and 2021). Trusted sources include the Bank of Ghana, XE (Xchange Express), and OANDA (Online and Direct Access).
2. Record the exchange rate for each year (2019, 2020, and 2021). For example:
2019: 1 USD = GH¢ 5.6
3. Create a simple graph that shows how the exchange rate of the Ghanaian cedi to the US dollar changed from 2019 to 2021. To create a simple graph showing how the exchange rate changed over these years, a line graph would be the best choice. It clearly illustrates trends over time.
• Use the horizontal or x-axis for the year and start at 2018.
• Choose your own scale for the y-axis for each chart and start at a number just below the data for 2019.
• Ensure your axes have equal divisions to maintain consistency and readability.
• Clearly label the x-axis with the years and the y-axis with the relevant units Finally provide a title for each chart to clearly indicate what it represents (e.g., “Exchange Rate in Ghana (2019-2021)”).
4. Compare how the exchange rates have changed each year. Note that an increase in the exchange rate means the cedi has weakened and vice versa.
5. Consider the effects of a weak vs. strong Ghanaian cedi on the prices of goods that Ghana imports or exports and answer the following questions:
a. What trend (up, down or stayed the same) did exchange rates between the Ghanaian cedi and the US dollar follow from 2019 to 2021?
b. When the cedi is weak (higher exchange rate), how might this have affected the cost of imports in Ghana?
c. When the Cedi is strong (lower exchange rate), how might this have affected Ghanaian exports?
d. Do you think a weak currency is always bad for the economy? Explain your answer.
e. How would you explain the effect of a weak or strong currency on people in Ghana?
f. What advice would you give to the government to help manage the exchange rate to benefit the economy?
6. Prepare a PowerPoint presentation with your findings. Present this to the class for discussion and feedback.
Control policies are actions that a government or central bank takes to manage the economy and keep it stable. These policies can control things like inflation, unemployment, and economic growth. The two main types of control policies are monetary policies (which involve controlling the money supply and interest rates) and fiscal policies (which involve government spending and taxation).
1. Monetary policies Monetary policies are actions taken by a country’s central bank (e.g., Bank of Ghana) to control the supply of money and interest rates in the economy. By changing interest rates or the amount of money in circulation, the central bank tries to control inflation, encourage spending, and keep the economy stable. There are two main types of monetary policy:
a. Expansionary Monetary Policy is when the central bank lowers interest rates or increases the money supply to encourage people to borrow, spend, and invest more, helping to boost the economy.
b. Contractionary Monetary Policy is when the central bank raises interest rates or reduces the money supply to slow down spending and control inflation in the economy.
2. Fiscal Policy
Fiscal Policy is when the government uses its spending and taxation to influence the economy, aiming to control factors like inflation, unemployment, and economic growth. There are two main types of fiscal policy:
a. Expansionary Fiscal Policy is when the government increases its spending and/or cuts taxes to boost the economy, especially when it is slowing down or in a recession. This encourages people to spend and businesses to invest more.
b. Contractionary Fiscal Policy is when the government reduces its overall spending and/or raises taxes, usually to control inflation when it is growing too fast.
3. Exchange-Rate Policy
Exchange Rate Policy is a government’s strategy to control the value of its currency relative to other currencies, affecting trade and investment. There are different approaches to exchange rate policy:
a. Fixed Exchange Rate is when a country’s currency is tied to another currency, like the US Dollar, and stays at a set value.
b. Floating Exchange Rate is when a country’s currency value is determined by market forces (supply and demand) and can change freely.
c. Managed Float is a mix where a currency mostly floats but the government occasionally steps in to influence its value if needed. Ghana’s situation is mostly a managed float because market forces usually determine the exchange rate, and the central bank occasionally intervenes to stabilise the exchange rate.
4. Trade Policy
Trade Policy refers to the rules and laws a country uses to manage trade with other countries, deciding what can be imported and exported, and how it is taxed. These can include:
a. Tariffs: These are taxes that a country charges on goods from other countries, making them more expensive, thus encouraging people to buy locally produced goods and services.
b. Quotas: These are limits set by a country on how much of a certain product can be imported from other countries, to protect local businesses.
c. Trade Agreements: They are deals between countries to agree on the terms of trade, like how much they can import and export and what tariffs or rules will apply.
5. Income Policy
Income Policy refers to government actions aimed at controlling how much people earn and how much businesses charge for goods and services to prevent high inflation.
These can include:
a. Wage and Price Controls: They are government rules that set limits on how much wages (salaries) and prices for goods and services can increase, to keep inflation low.
b. Indexation Policies: These are rules that automatically adjust wages, pensions, or taxes based on inflation, so people’s income is not affected by rising prices.
Activity 8.4 Exploring Control Policies in Ghana
Instructions This activity will help you to understand the control policies used in Ghana and how these policies affect inflation, the exchange rate, and unemployment.
1. Using the internet or your textbook, list three control policies used by the Bank of Ghana to manage the economy, such as monetary policy.
2. Choose two policies from the list you made in 1 and describe how they work.
3. Think about how these control policies impact the economy and answer the following questions:
a. What are the three main control policies used in Ghana?
b. Explain two of these policies in detail.
c. How do these policies affect inflation, exchange rate, and unemployment in Ghana?
d. How do these control policies affect people like you and your family?
Think about the price of food, fuel, and jobs.
4. Prepare your report with your findings. The report should not be more than one page.
5. Present this to the class for discussion and feedback.
National Income
National income is the total value of all the goods and services produced in a country over a specific period, usually a year. In Ghana, it helps to measure the country’s overall economic activity and shows how well the economy is performing. It includes factors like the income people earn from their jobs, profits businesses make, and taxes collected by the government. National income is important because it helps the government to make decisions about spending, taxes, and how to improve the country’s economy.
National income can be calculated in several ways, including:
1. Gross Domestic Product (GDP) is the total value of all goods and services produced within a country’s borders in a specific period, usually a year.
2. Gross National Product (GNP) is the total value of all goods and services produced by a country’s residents, both inside and outside the country. It is calculated by adding GDP to the net income from abroad (income from foreign investments minus payments to foreign investors).
3. Net National Product (NNP) is the total value of goods and services produced by a country’s residents, after subtracting the depreciation (wear and tear) of capital goods. It is GNP minus depreciation.
4. National Income (NI) is the measure of NNP that excludes indirect taxes (like sales tax) and includes subsidies (NNP minus indirect taxes plus subsidies; thus NNP – indirect tax + subsidies).
National Income can be calculated using three methods: the product (or output) approach, the income approach, and the expenditure approach.
Activity 8.5 Understanding National Income
Instructions This activity will help you to understand national income and how countries, like Ghana, calculate national income using the product, the expenditure, and the income approach.
1. Think of five examples of things you use or consume (for example, food, clothing, transportation).
a. Where do you think the money spent on these items goes?
b. Does it contribute to the national income? Why?
For example, if you buy a loaf of bread, the money paid to the bakery helps the bakery earn income, the sales tax charged than contributes to the national income of the country.
2. Think of a local business (for example, a cocoa farm or a bakery shop) and discuss how each of the three methods of calculating national income would work for that business.
a. How would you measure the national income from this business using the product approach? Focus on the values of the products they produce or sell.
b. How would you measure the national income from this business using the expenditure approach? Focus on how much money people spend on their business.
c. How would you measure the national income from this business using the income approach? Focus on the money workers and business owners receive.
3. Create a simple poster or infographic that shows the three ways to calculate national income (product, expenditure, and income) using examples from Ghana.
4. Prepare a short report on your findings using text, audio recording, or PowerPoint presentation.
5. Compare your findings with your friend in the class.
The next part of section 8 will explain how to calculate National Income by using the Product Approach. The product approach is often called the output approach by economists because the method emphasises the output or production side of the economy.
The product approach (output approach) looks at the total value of all the goods and services produced in a country. In other words, it measures the monetary value of products a country makes in a year, whether it is food, cars, clothes, or even services like teaching or healthcare. It focuses on the output or production generated by various sectors (primary, secondary, and tertiary) of the economy.
Consider the data below that represents a range goods and services produced in Ghana:
Items Amount (Gh₵)
Cocoa Beans 1,000,000
Gold Mining 2,500,000
Limestone for making cement 200,000 Cement Manufacturing 800,000 Cocoa Processing 1,200,000 Retail Trade 1,000,000 Transportation Services 600,000 Income from foreign investments 450,000 Payments to foreign investors 380,000 Depreciation (consumption of fixed capital) 100,000 Indirect taxes 150,000 Subsidies 180,000 Follow the steps below to calculate national income by using the product approach.
Step 1: Identify and Classify Production into sectors Agriculture Mining and Manufacturing Services Cocoa Beans (raw material for processing) Gold Mining Retail Trade Limestone for making cement Transportation Services Cement Manufacturing Cocoa Processing
Step 2: Add up the value of what each sector produces The gross value of output is simply the total value of goods and services produced in each sector. Based on the table, the gross output for each sector is as follows:
1. Agriculture Sector: Cocoa Beans = Gh1,000,000
2. Mining and Manufacturing Sector:
Gh₵ Gold Mining 2,500,000
Limestone for making cement 200,000 Cement Manufacturing 800,000 Cocoa Processing 1,200,000 4,700,000
3. Services Sector:
Gh₵ Retail Trade 1,000,000
Transportation Services 600,000
1,600,000
Step 3: Calculate Intermediate Consumption
Intermediate goods are products used in the production of other goods. These are not included in the final output because they are used up during the production process so need to be subtracted.
From the table, intermediate goods are Limestone for making cement (Gh₵ 200,000) and Cocoa Beans (Gh₵ 1,000,000) The value of intermediate goods used in production is Gh₵ 1,200,000 in total (200,000 + 1,000,000).
Step 4: Subtract Intermediate Consumption from Gross Output (Gross Value Added) To calculate the Gross Value Added (GVA) for each sector, subtract the value of intermediate goods from the gross value of output:
Mining and Manufacturing Sector
Cement Manufacturing
Gross Output: Gh₵ 800,000
Intermediate Consumption: Gh₵ 200,000 (for limestone used in cement) GVA for Cement Manufacturing: 800,000 - 200,000 = Gh₵ 600,000 Cocoa Processing Gross Output: Gh₵ 1,200,000 Intermediate Consumption: Gh₵ 1,000,000 (for cocoa beans used in processing) GVA for Cocoa Processing: 1,200,000 - 1,000,000 = Gh₵ 200,000
Step 5: Sum the Gross Value Added (GVA)
Now, you add up the GVA from all sectors to get the Gross Domestic Product (GDP) GDP = (GVA from Agriculture) + (GVA from Mining and Manufacturing) + (GVA from Services) GDP = 1,000,000 + 2,500,000 + 600,000 + 200,000 + 1,000,000 + 600,000 = Gh₵ 5,900,000
Step 6: Add GDP to net income from abroad to get Gross National Product (GNP) GNP = GDP + the net income from abroad (income from foreign investments minus payments to foreign investors) GNP = 5,900,000 + (450,000 – 380,000) GNP = 5,900,000 + 70,000 GNP = Gh₵ 5,970,000
Step 7: Subtract depreciation from GNP to get Net National Product (NNP) NNP = GNP – Depreciation NNP = 5,970,000 – 100,000 NNP = Gh₵ 5,870,000
Step 8: Adjust NNP with indirect taxes and subsidies to get National Income (NI) National Income (NI) = NNP – Indirect Taxes + Subsidies National Income (NI) = 5,870,000 – 150,000 + 180,000 National Income (NI) = Gh₵ 5,900,000
Activity 8.6 Calculating National Income Using the Product Approach Materials Needed: (Pen and paper, a calculator (optional) and the data provided below).
Instructions
1. Study the data in the table to get an understanding. You are provided with the following data to calculate national income using the product approach:
Sector/Industry Amount (GHS)
Agriculture 20,000,000 Manufacturing 30,000,000
Services 30,000,000 Construction 15,000,000
Energy (Electricity, gas, solar) 10,000,000 Subsidies 3,000,000 Indirect taxes 4,000,000 Income received from abroad 4,200,000 Income paid abroad 3,900,000 Depreciation 2,200,000 (Note that income paid abroad is the earnings generated by foreign factors of production, such as land, labour, and capital, that are located within the country AND income received from abroad refers to the earnings generated by factors of production, such as land, labour, and capital, that are located in other countries but are owned by residents of the home country.)
2. Identify the key components of the product approach. These include products of the sectors and indirect taxes.
3. Add the values of final goods produced by all sectors to get the gross domestic product (GDP). That is, GDP = (Agriculture + Manufacturing + Services + Construction + Energy)
4. Add GDP to net income from abroad to get Gross National Product (GNP).
That is, GNP = GDP + the net income from abroad (income received from abroad – income paid abroad).
5. Subtract depreciation from GNP to get Net National Product (NNP). That is NNP = GNP – Depreciation
6. Adjust NNP by subtracting indirect taxes and adding subsidies to get National Income (NI). That is, National Income (NI) = NNP – Indirect Taxes + Subsidies.
7. Record your findings in your exercise book or Microsoft Word.
8. Share your findings with your friends in class.
Expenditure Approach
To calculate national income using the expenditure approach looks at how much money is spent on goods and services in an economy. It adds up all the spending by households, businesses, the government, and foreigners (through exports) to find the total value of a country’s production. This approach focuses on the total spending on final goods and services. The expenditure approach involves:
1. Consumption (C): This is the money people (households) spend on goods and services, like food, clothes, and entertainment.
2. Investment (I): This is the money businesses or people spend on things like new factories, equipment, or land to help make more goods in the future.
3. Government Spending (G): This is the money the government spends on things like schools, roads, hospitals, and security to help the country run smoothly.
4. Net Exports (X - M): This is the difference between the money a country earns from selling goods to other countries (exports) and the money it spends buying goods from other countries (imports).
Consider the following data for National Income Calculation (Expenditure Approach) Items Amount (in Gh₵) Household Consumption (C) 4,000,000 Business Investment (I) 1,500,000 Government Spending (G) 2,000,000 Exports (X) 1,200,000 Imports (M) 800,000 Income from foreign investments 620,000 Payments to foreign investors 500,000 Consumption of fixed capital 200,000 Subsidies 220,000 Indirect Taxes 180,000 Steps to Calculate National Income using the Expenditure Approach
Step 1: Add all the spending in the country during the period Gross Domestic Expenditure (GDE) = Household Consumption (C) + Business Investment (I) + Government Spending (G) + (X - M) GDP = 4,000,000 + 1,500,000 + 2,000,000 + (1,200,000 – 800,000) GDP = Gh₵ 7,900,000
Step 2: Adjust for Depreciation (D) to arrive at Net Domestic Expenditure (NDE). Subtract depreciation to account for the consumption of fixed capital.
Net Domestic Expenditure (NDE) = GDE – D NDE = 7,900,000 – 200,000 NDE = Gh₵ 7,700,000
Step 3: Add Net Foreign Factor Income to NDE to get Net National Expenditure (NNE).
Net National Expenditure (NNE) = NDE + Net factor income from abroad Net National Expenditure (NNE) = 7,700,000 + (620,000 – 500,000) NNE = Gh₵ 7,820,000
Step 4: Subtract Indirect Taxes (T) and Add Subsidies (S) to arrive at the National Income (NI).
Net National Expenditure (NNE) = NNE – T + S Net National Expenditure (NNE) = 7,820,000 – 180,000 + 220,000 Net National Expenditure (NNE) = Gh₵ 7,860,000 The national income is simply calculated as:
NI = GDP − Depreciation + Net Foreign Factor I n come − I n direct Taxes + Subs idies NI = 7,900,000 – 200,000 + (620,000 – 500,000) – 180,000 + 220,000 NI = Gh₵ 7,860,000 The national income from the table above is Gh₵ 7,860,000
Activity 8.7 Calculating National Income Using the Expenditure Approach Materials Needed: (Pen and paper, a calculator (optional), and the data provided below) Instructions
1. Go through the table to understand the data in it. You are provided with the following data to calculate national income using the expenditure approach:
Item Amount (GHS)
Consumption (C) 40,000,000 Investment (I) 20,000,000
Government Spending (G) 15,000,000
Net Exports (Exports - Imports) 10,000,000 Net Factor Income from Abroad (2,000,000) Consumption of Fixed Capital 1,500,000 Indirect Taxes 4,000,000 Subsidies (5,000,000)
2. Identify the key components of the expenditure approach. Key components include consumption (C), investment (I) and subsidies (S).
3. Identify and classify production into sectors (that is, Agriculture, Manufacturing and Services).
4. Add the Gross Values of expenditure items to get gross domestic expenditure (GDE). That is, consumption(C) + investment (I) + government spending (G) + (export (X) – import (M))
5. Add GDE to net income from abroad to get Gross National Expenditure (GNE). That is, GNE = GDE + the net income from abroad (income from abroad – income paid abroad)
6. Subtract depreciation from GNE to get Net National Product (NNE).
That is, NNE = GNE – Depreciation
7. Subtract indirect taxes and add subsidies to NNE to get National Income (NI)
8. National Income (NI) = NNP – Indirect Taxes + Subsidies
9. Now answer the following questions:
a. How did the net factor income from abroad affect the national income calculation?
b. Why do you subtract subsidies from the indirect taxes?
c. What is the significance of consumption of fixed capital in the national income calculation?
10. Record your findings in your exercise book or Microsoft Excel.
11. Share your findings with your friends in class.
To use the income approach to calculate national income, look at how much money people earn in an economy. It adds up all the income earned from jobs, businesses, and other sources, like wages, profits, and taxes in a country.
How to Use the Income Approach to Calculate
National Income
Consider the following data for National Income Calculation (Income Approach) Item Amount (in Gh₵) Wages and Salaries (Income from work) 3,000,000 Profits of Businesses 2,500,000 Rental Income (Income from land or property) 1,000,000 Interest Income (Earnings from savings or investments) 500,000 Taxes on production and imports (e.g., VAT, excise duties) 1,200,000 Subsidies on products or services (government subsidies) 200,000 Depreciation 250,000 Income from foreign investments 290,000 Payments to foreign investors 300,000
Step 1: Identify and Classify Income Sources (Identify the various sources of income that contribute to the national income).
1. Wages and Salaries: This refers to the income people receive from their jobs. For
example, if people in Ghana earned a total of Gh₵ 3,000,000 in wages, it would be added to the national income.
2. Profits of Businesses: The total profits businesses make (after paying expenses).
From the table above, the profits of businesses are Gh₵ 2,500,000.
3. Rental Income: People who own land or property receive income from renting it out. Suppose this income is Gh₵ 1,000,000.
4. Interest Income: People also earn money from savings or loans (interest). For
example, Gh₵ 500,000 from interest might be earned.
Total income = 3,000,000 + 2,500,000 + 1,000,000 + 500,000 = Gh₵ 7,000,000
Step 2: Adjust for Indirect Taxes and Subsidies: Add indirect taxes (such as sales tax, and excise tax) of Gh₵ 1,200,000 and subtract subsidies of Gh 200,000 to adjust the income figures to reflect the market prices of goods and services.
National income = 7,000,000 + 1,200,000 - 200,000 = Gh₵ 8,000,000
Step 3: Adjust for Depreciation (Consumption of Fixed Capital): Subtract depreciation of Gh₵ 250,000 to account for the loss of value of capital assets over time.
National income = 8,000,000 - 250,000 = Gh₵ 7,750,000
Step 4: Adjust for Net Factor Income from Abroad: Include the net income earned from abroad, which is the difference between income earned by residents from overseas investments and income earned by foreigners from domestic investments.
National income = 7,750,000 + (290,000 – 300,000) National income = 7,750,000 – 10,000 National income = Gh₵ 7,740,000 Therefore, the formula for calculating national income (NI) using the income approach can be summarised as:
NI = Compen s ation of employees + Ren ts + P rof its + I n teres t + I n direct Taxes - Subs idies - Depreciation + Net Factor I n come Abroad From the table above:
National Income (NI) = 3,000,000 + 1,000,000 + 2,500,000 + 500,000 + 1,200,000 - 200,000 - 250,000 + (290,000 – 300,000) National Income = Gh₵ 7,740,000
Activity 8.8 Calculating National Income Using the Income Approach Materials Needed: (Pen and paper, a calculator (optional) and the data provided below) Instructions
1. Study the data in the table to get an understanding. You are provided with the following data to calculate national income using the product approach:
Items Amount (GHS)
Wages and Salaries 50,000,000
Rent 10,000,000 Interest 5,000,000
Profits 15,000,000 Depreciation 1,000,000
Income paid abroad 2,500,000 Income from abroad 3,000,000 Indirect Taxes 7,000,000 Subsidies (2,000,000)
2. Identify the key components of the income approach. For example, rent, interest and income received from abroad
3. Identify the various sources of income that contribute to the national income and add them to get GDP (That is, GDP = wages and salaries + rent + interest + profits).
4. Add net factor income from abroad to GDP to arrive at GNP (That is, GNP = GDP + Net factor income from abroad).
5. Subtract depreciation from GNP to get NNP (That is, NNP = GNP - D).
6. Add indirect taxes and subtract subsidies to arrive at the final national income (NI = NNP + Indirect taxes - Subsidies).
7. Record your findings and compare them to friends’ work in the class.
Uses of National Income
National income has several key uses. It is used for economic planning, policymaking, and assessing a country’s economic performance, living standards, investment trends, international economic relations, and sectoral contributions.
1. Economic Planning and Policy Making: National Income data helps governments create budgets and allocate resources efficiently. It also guides the development of monetary, fiscal, and trade policies.
Example: The Ghanaian government uses national income data to create the Ghana Shared Growth and Development Agenda (GSGDA), which outlines policies to boost economic growth and development.
2. Measuring Economic Performance: National Income evaluates a country’s economic growth rate and allows comparison with other countries’ performances.
Example: Ghana monitors its GDP growth rates to evaluate economic performance. For instance, the government assesses whether growth targets are met and compares performance with other West African countries.
3. Standard of Living Assessment: National Income assesses average income per person (per capita income), indicating the standard of living and highlighting income inequality within the country.
Example: By analysing per capita income, Ghana can assess the standard of living across different regions, helping to identify areas needing targeted social interventions and development programs.
4. Investment and Savings: National Income influences both public and private sector investment decisions and monitors the savings rate, crucial for future investment and growth.
Example: National income data helps the Ghanaian government and private sector identify trends in savings and investments. This information is used to encourage investments in key sectors like agriculture, mining, and technology.
5. International Economic Relations: National Income data is used to determine eligibility and needs for foreign aid and loans. It also helps in formulating international trade policies and agreements.
Example: Ghana’s national income data is critical when applying for international loans and aid. Organisations like the IMF and World Bank use this data to evaluate Ghana’s economic health and creditworthiness.
6. Sectoral Analysis: National Income is used to evaluate the performance of various sectors like agriculture, manufacturing, and services. It aids in the effective allocation of resources among different sectors.
Example: By examining the contributions of various sectors to national income, Ghana can focus on boosting the performance of its cocoa industry, which is a significant part of the economy, as well as other sectors like oil and gold mining.
The Importance of National Income
National income is important because it provides a comprehensive measure of a country’s economic health and stability. It guides government policy, supports economic planning, and helps work out living standards.
1. Indicator of Economic Health: National Income shows how healthy and stable the economy is. It helps to watch and control prices going up or down.
Example: Ghana uses national income data during tough times or fast growth to see if the economy is getting better or worse.
2. Employment Generation: National income is linked to creating jobs and how much people get paid. Example: Growth in national income in Ghana, especially from oil, has created jobs and reduced unemployment, especially for young people.
3. Social and Economic Policies: National Income helps to plan and fund social programs and improve public services like healthcare and education. Example:
Ghana uses national income to support programs like the National Health Insurance Scheme (NHIS) and Free Senior High School (SHS) to improve access to healthcare and education.
4. Economic Stability and Growth: National Income helps keep the economy stable and supports long-term growth. Example: Continuous national income growth has helped Ghana stay stable and work on long-term goals, like the “Ghana Beyond Aid” vision.
5. Public and Private Sector Decision Making: National income provides important information for business and government planning. Example:
Businesses in Ghana use national income data to decide on expansion, and the government uses it to plan projects like roads and energy facilities.
6. Taxation and Revenue: It helps design effective tax policies and ensures the government has enough money for spending. Example: The Ghana Revenue Authority (GRA) uses national income data to create tax policies and collect revenue efficiently, which funds public services and development projects.
