What is Economic Methodology & the Economic Problem?

A-Level Economics starts with the fundamental economic problem: infinite wants and needs clashing with scarce resources. This scarcity forces economic agents (individuals, firms, governments) to make choices, leading to opportunity costs – the value of the next best alternative foregone. Economic methodology involves building and testing models based on assumptions to understand this behaviour, distinguishing between objective, testable positive statements and subjective, value-based normative statements.

Board notes: This topic is a fundamental concept covered by all major A-Level Economics exam boards, including AQA, Edexcel, and OCR. The core principles of scarcity, choice, opportunity cost, and the distinction between positive and normative statements are foundational to all specifications.

Worked example

Common mistakes

• 1Confusing the economic problem with just 'running out of money'. The core issue is the scarcity of real resources (like land, labour, capital) relative to the unlimited desires for goods and services.
• 2Stating that a positive statement is a 'fact'. While positive statements are based on facts and can be tested, they can still be proven false. For example, 'An increase in the minimum wage will cause unemployment' is a positive statement, but it may not be true in all circumstances.
• 3Thinking opportunity cost is the same as the monetary price. The opportunity cost is the value of the *next best alternative* you give up, which might not have a direct monetary value, such as the lost study time when choosing to go to the cinema.

Frequently asked questions

• What is the difference between a positive and a normative statement in economics?

  A positive statement is an objective statement that can be tested against evidence to be proven true or false, such as 'A fall in the price of a good will lead to an increase in the quantity demanded.' A normative statement is a subjective opinion or value judgement that cannot be tested, like 'The government should increase the minimum wage to reduce poverty.'

• Why do we have to make choices in economics?

  We have to make choices because of scarcity. Economic resources like land, labour, and capital are finite, but human wants for goods and services are infinite. This fundamental imbalance means we cannot have everything we want, forcing us to choose which wants to satisfy and which to leave unsatisfied.
