August 2023 Question One A

State FIVE advantages of a planned economy.    (5 marks)


A planned economy is an economic system in which the government controls the production, distribution, and prices of goods and services. This is in contrast to a market economy, where these decisions are made by private businesses.

There are several advantages of a planned economy:

  • Efficiency: The government can allocate resources more efficiently than the market, as it has a better overview of the economy. This can lead to lower production costs and higher output.
  • Equality: The government can ensure that everyone has access to basic necessities, such as food, housing, and healthcare. This can lead to a more equal society.
  • Stability: The government can control the economy and prevent boom-and-bust cycles. This can lead to a more stable economy.
  • Rapid economic growth: The government can direct investment and resources towards strategic industries, which can lead to rapid economic growth.
  • Avoiding market failures: The government can intervene in the market to correct market failures, such as monopolies and externalities.



August 2023 Question Six B

Analyse FOUR challenges that may be encountered by an economy when transitioning from a planned economy to a free enterprise system.    (4 marks)



Transitioning from a planned economy to a free enterprise system is a complex and challenging process. There are a number of factors that can make this transition difficult, including:

  • Lack of experience with a market economy: In a planned economy, the government controls most aspects of the economy, including production, distribution, and prices. This means that businesses and individuals have little experience with making decisions in a market economy.
  • Weak institutions: A market economy requires strong institutions, such as a legal system that protects property rights and a financial system that can channel capital to businesses. In many countries that are transitioning from a planned economy, these institutions are weak or nonexistent.
  • Corruption: Corruption can be a major obstacle to economic reform. In countries where corruption is widespread, businesses may be reluctant to invest or operate in a market economy.
  • Political instability: Political instability can also make it difficult to implement economic reforms. If there is frequent change in government, it can be difficult to maintain a consistent policy course.
  • Social unrest: The transition from a planned economy to a free enterprise system can lead to social unrest. This is because the transition can lead to job losses and changes in the way that people live and work.



April 2023 Question One B

Enumerate FIVE benefits of studying economics.      (5 marks)


  • Excellent career prospects: By having economic knowledge, you will have many excellent job prospects and potential career paths available to you. Economists play an important part in everyday life and are present in all sectors of business, meaning economics graduates are in high demand by employers around the world.
  • Study of Economics helps to conquer poverty: Economics studies the, vital question of satisfying human wants with scarce resources. The present day poverty and the poor standard of living of the people of many backward countries are due to poor resources, little production and lack of technology. The knowledge of economics is essential to eradicate poverty of a nation and to raise their living standards.
  • Develop transferrable skills: One of the best reasons for studying economics is the development of transferrable skills. These skills can be applied to any field of economics and will also boost your employability in any industry you choose to work in.
  • Study of Economics helps to frame law: The knowledge of economics is very essential for the legislators and parliamentarians. They will be able to frame laws effectively only by having knowledge of the subject. As citizens and voters and people. Electing the representatives, the knowledge of economics will be much helpful. It will help the people to understand many economic programmes presented by the political parties in their ‘Election Manifesto’. The people can wisely judge the truth of the statements in the Manifesto.
  • Study of Economics helps to increase national wealth: By studying economics, we can discover new factors that may lead to increase the national wealth. Modern governments are actively engaged in economic Planning. The purpose of planning is to remove poverty by increasing the national income and wealth and also by effectively distributing the wealth. Without the knowledge of economics, this is absolutely impossible.
  • Prepare for the Future: Studying economics helps you prepare for the future. You’ll have a grasp of the economic principles that affect your career prospects, investment decisions and retirement strategies. While other people are more uncertain about the economy and how to adjust to changing conditions, you can make better-informed choices and come up with ideas to deal with problems and benefit from opportunities.



December 2022 Question One C

List FOUR characteristics of economic resources.   (4 marks)



Characteristics of economic resources

  • Scarce: Economic resources are limited in availability and cannot meet all the unlimited wants and needs of society.
  • Alternate use: Economic resources can be used for multiple purposes, and the opportunity cost of using them for one purpose is the next best alternative use.
  • Transformation: Economic resources can be transformed into other useful resources through production processes.
  • Economic value: Economic resources have an economic value, which is determined by their ability to satisfy human wants and needs.
  • Excludability: Economic resources can be excluded from use by some people, meaning only certain individuals can use them.
  • Rivalrousness: Economic resources are rivalrous, meaning their use by one individual reduces the availability for use by others.
  • Transferable: Economic resources can be moved or transferred from one person or group to another.



December 2022 Question Three A

Enumerate FIVE factors that could limit consumer sovereignty.     (5 marks)



Factors that can limit consumer sovereignty                   

  • Advertising: Advertising campaigns can create the illusion of choice, when in reality the products or services being offered are all very similar.
  • Monopolies / oligopolies: When a few companies dominate a market, they can limit consumer choice and can charge higher prices that could not be possible in a competitive market
  • Government regulations: Government may impose restrictions or regulations on certain products or services, limiting consumer choices.
  • Limited financial resources: Consumers may not be able to afford the products and services they would like due to financial constraints.
  • The nature of economic System: In general, the consumer is more sovereign in a free market oriented system where commodities are produced more in line with consumer preferences. In a planned economic systems, less regard is given to consumer preferences.
  • The range of goods available: Different consumers have different individual tastes and preferences and it is difficult for the available range of goods and services to satisfy all the consumers.
  • Consumer habits: Individual consumers have different habits and are often reluctant to change these habits.



December 2022 Question Six A

Outline FOUR disadvantages of a controlled market system.    (4 marks)



Disadvantages of a controlled market system                         

  • Limited competition
  • Inefficient allocation of resources

  • Unfairness



August 2022 Question One A

Explain five demerits of trade liberalisation in an economy.  (5 marks)



Demerits of trade liberalisation in an economy                           

Trade liberisation involves removing barriers to trade between different countries and encouraging free trade. It has the following disadvantages:

  • Structural unemployment: It often leads to a shift in the balance of an economy. Some industries grow, some decline. Therefore, there may often be structural unemployment from certain industries closing
  • Environmental costs: It could lead to greater exploitation of the environment e.g greater production of raw materials, trading toxic waste to countries with weaker environmental laws
  • Infant industry argument: It may be damaging for developing countries who cannot compete against free trade.
  • Due to liberalization, there will be an increased dependence on other nations, for forex, technology etc
  • The domestic sector will take a hit as industries will become dependent on cheap raw materials from foreign countries.
  • Due to introduction of new technology, there will be less workers who can implement the technology.
  • There will be economic instability as any changes in the currency in foreign markets will result in a significant impact on the economy.



April 2022 Question One A

Discuss five challenges encountered by planned economic system in their transition to market oriented economies.        (10 marks)



Challenges encountered by planned economic system in their transition to market oriented economies.  

  • Initial decline in output as the work culture develops may lead to loss in tax revenues at a time. When growing poverty has increased the need for increased social spending.
  • Introduction of price mechanism: This may indicate a lot of commodities produced previously are no longer needed resulting to unemployment.
  • There’s danger of escalation of legitimate market institutions.
  • The need to develop an entrepreneurship culture which was not encouraged in planned economies. This is a culture that encourages risk taking and hard work.
  • The need to introduce private and property rights which determines who owns what, which may prove challenging.



December 2021 Question One D

Outline seven advantages of a free market economic system.      (7 marks)



Advantages of a free market economic system    

A free market system is where the people in an economy are free to engage in economic activities and transactions without government interference


  • Efficient allocation of resources
  • Competition
  • Innovation and economic growth
  • More choice
  • Absence of red tape
  • The free market economy naturally promotes equality
  • Free market economies regulate themselves naturally



August 2021 Question Six C

(i)     Define the term “free enterprise economic system.”        (1 mark)

(ii)    Highlight four economic advantages of free enterprise economic system.  (4 marks)



(i)     Definition of the term “free enterprise economic system.”              

Refers to an economic system where the price mechanism is given a free reign in resource allocation. Competition is the driving force of free enterprises, resulting in greater efficiency and lower prices for the consumer.


(ii)    Economic advantages of free enterprise economic system.           

  1. Absence of red tape
  2. Freedom to innovate
  3. Customers drive choice

 Incentive: people are encouraged to work hard because opportunities exist for individuals to accumulate high levels of wealth



May 2021 Question One A

Evaluate four ways in which the government could influence allocation of resources in a country. (8 marks)



Ways in which the government could influence allocation of resources in a country

  • Indirect taxes: indirect taxes can be used to raise the price of de-merit goods and products with negative externalities designed to increase the opportunity cost of consumption and thereby reduce consumer demand towards a socially optimal level.
  • Subsidies: subsidies to consumers will lower the price of merit goods. They are designed to boost consumption and output of products with positive externalities – remember that a subsidy causes an increase in market supply and leads to a lower equilibrium price.
  • Provision of goods and services: Because of privatization, the state owned sector of the economy is much smaller than it was years ago. State funding can also be used to provide merit goods and services and public goods directly to the public.
  • Tax relief: the government may offer financial assistance such as tax credits for business investment in research and development. Or a reduction in corporation tax designed to promote new capital investment and extra employment.
  • Legislation and regulation. employment laws may offer some legal protection for workers by setting maximum working hours or by providing a price-floor in the labor market through the setting of a minimum wage regulation may be used to introduce fresh competition into a market- for example breaking up the existing monopoly power of service provider.



May 2021 Question One C

(i)  Define the term “Consumer Sovereignty” as used in economics.       (2 marks)

(ii) Summarise six limitations of consumer sovereignty in an economy.  (6 marks)



(i)  Term “Consumer Sovereignty” as used in economics. (Nov 2018 1B)       

This is an economic belief that societal welfare is maximized when consumers are at liberty to choose goods to satisfy their needs. Simply, the consumer is the best judge of their product choices.


(ii) Limitations of consumer sovereignty in an economy.  

  • Government policy through taxes and subsidies can influence choices made by consumer.
  • Nature of economic system e.g. in a command economy, government dictates what a consumer should do.
  • Irrationality of consumer
  • Advertising also restricts the consumer’s choice.
  • Type of market e.g. in monopolies consumers have limited choice.
  • Income of consumer products are only made for rich guy and the choices of the poor are never considered
  • In availability of goods means consumers has to use what is available.
  • Technical factors may impinge on freedom of consumer. For example the existing technology may not allow producers to make goods desired by consumers.
  • Habit individual consumers have different and are reluctant to charge
