Scarcity - A-Level Economics
Scarcity
Scarcity and the Economic Problem
The economic problem is that of scarcity, where people have unlimited wants in the face of limited resources. Famine and drought are extreme forms of scarcity, but the wealthy still face scarcity because resources are limited so not all material wants can be satisfied.
Factors of Production
Factors of production are resources which are used in the production process, including labour, capital, land and entrepreneurship.
The production process requires both human and physical resources:
Labour refers to the workers that are required for production
Land includes all natural resources used, including raw materials (e.g. coal) and land space.
Capital: goods that are specifically manufactured with the sole purpose of producing other goods (e.g. a factory)
Entrepreneurship bear the risk of the project and bring all factors of production together to produce an output.
Labour and entrepreneurship are human resources; land is a physical resource.
Choice
The existence of scarcity forces people to make choices:
- Consumers have to choose which goods and services to consume. They need to prioritise the consumption of goods that they need or really want because they cannot satisfy all of their wants.
- Governments have to choose between alternative ways to use resources such as money or fossil fuels. For example, if the local council improves street bins, they might not be able to fund street paving.
- Producers have to choose how to use money and factors of production to produce goods to maximise profits.
Therefore consumers, producers and the government all face the economic problem.
Scarcity refers to the condition where resources are limited in comparison to the unlimited wants and needs of society. In other words, scarcity is the fundamental economic problem of having seemingly unlimited human wants in a world of limited resources.
There are several causes of scarcity, including natural disasters, population growth, inadequate production and distribution systems, government policies, and changes in consumer preferences.
Scarcity forces individuals, firms, and governments to make choices about how to allocate resources among competing needs and wants. Economic decision-making involves weighing the benefits and costs of different choices and selecting the option that maximizes utility or satisfies the most important needs and wants.
Opportunity cost is the cost of giving up one alternative to pursue another. It is the value of the next best alternative that must be sacrificed in order to choose a particular option. Opportunity cost is a key concept in economics and is closely related to the idea of scarcity.
Markets allocate scarce resources through the mechanism of price. Prices serve as signals that communicate information about the scarcity of resources and the wants and needs of consumers. When resources are scarce, prices tend to rise, which signals to consumers that they should conserve resources or find alternative substitutes.
Some strategies for managing scarce resources include conservation, innovation, and the use of alternative substitutes. Conservation involves reducing waste and using resources more efficiently. Innovation involves developing new technologies or production methods that reduce the demand for scarce resources. The use of alternative substitutes involves finding alternative sources of the resource or using different resources altogether.
Scarcity plays a significant role in global issues such as poverty and environmental sustainability. Poverty is often the result of a lack of access to resources, particularly in developing countries. Environmental sustainability involves balancing the use of resources with the need to preserve the natural environment for future generations. Both issues require careful management of scarce resources to ensure equitable and sustainable use.
