This topic introduces economics as a social science, focusing on the fundamental economic problem of scarcity, the necessity of choice, and the allocation of resources. It covers the methodology of economic enquiry, the distinction between positive and normative statements, the role of value judgements, and the use of production possibility diagrams to illustrate key economic concepts.
Economic methodology is the study of how economists think, test theories, and build models. It covers the distinction between positive and normative statements, the use of the ceteris paribus assumption, and the role of value judgments in economic analysis. Understanding this foundation is crucial because it shapes how you evaluate economic arguments and data throughout the A-Level course.
The economic problem arises from the fundamental issue of scarcity: unlimited human wants but finite resources. This forces every economy to answer three key questions: what to produce, how to produce, and for whom to produce. The concept of opportunity cost—the next best alternative forgone—is central here, as it underpins all economic decision-making at individual, firm, and government levels.
Together, these topics form the bedrock of AQA A-Level Economics. They appear directly in Paper 1 (markets and market failure) and Paper 3 (economic principles and issues), and indirectly in every other topic. Mastering them early gives you a framework to critically analyse models like supply and demand, production possibility frontiers, and government intervention.
