Economic Activity, Needs, Goods and Factors of Production

Economic Activity and Key Economic Concepts

Economic activity is aimed at satisfying human needs using scarce resources in accordance with the principle of optimization. Microeconomics focuses on analyzing the behavior of economic agents taken into account individually: families, companies and the relationships established between them through the market. Macroeconomics is the part of economics that studies the economy as a whole. It analyzes the behavior of macroeconomic variables obtained from the sum of the actions of individual economic agents: national product, national income, consumption, investment, etc.

Human Needs and Classification

Human needs are commonly classified into different types. Understanding these distinctions helps explain consumption choices and policy priorities.

Primary Needs (Physiological)

The primary needs: Those whose satisfaction depends on the individual's survival. They have a physiological foundation and are common to all human beings, for example: breathing, eating, drinking, sleeping, etc.

Secondary Needs (Cultural and Social)

The secondary needs: Those whose satisfaction increases the welfare of the individual once primary needs are covered. They depend on cultural, social, economic and historical factors. Some examples are: watching a football game, connecting to the internet, etc.

Goods and Services

A good or service is whatever helps meet human needs.

Consumer Goods and Capital Goods

Consumer goods and capital goods: Consumer goods are those that directly meet human needs. Within this type there are durable goods, such as a car, and non-durable goods, such as food. Capital goods (or assets and capital) are those that do not directly satisfy human needs and are used to produce other goods, for example, a machine.

Public Goods and Private Goods

Public and private goods: Public goods are those that belong to society, can be used by all citizens, and from which no one can be excluded. For example: a public park. Private goods are those that belong to a particular individual or entity and whose use can be restricted to those who own or pay for them. For example: a television or a private school.

Complementary and Substitute Goods

Complementary and substitute goods: Complementary goods are those that must be used together to satisfy a need, such as gasoline and a car, or contact lenses and lens-cleaning solution. Substitute goods are alternatives from which a consumer chooses when satisfying a need, such as glasses and contact lenses, or taking a train and taking a bus.

Factors of Production

The factors of production are the set of resources that humans use to produce goods and services intended to satisfy needs.

Labor as a Production Factor

Labor: It is the personal contribution, both physical and intellectual, that humans provide to the production process. People involved in the production of goods and services form the employed population; together with the unemployed, they constitute the total population.

Land as a Production Factor

The land factor: Refers to all the resources that nature offers. It should be noted that many of the resources provided by nature have been extensively used by humans. In addition, one-third of the world population—the poorest and most marginalized—is directly dependent on what they grow, collect or capture. All these situations have raised awareness among certain social groups who demand their governments intervene in the control and recovery of this resource, which is increasingly fragile and scarce.

Note: Throughout the text, examples and categories are provided to illustrate how economic concepts connect: scarcity and optimization drive choices; needs determine demand; goods and production factors determine supply and capabilities.
