Key Areas of Focus:

1. What is Economics?
   • Economics as a social science.
   • Central concepts such as scarcity, choice, efficiency, equity, economic well-being, sustainability, change, interdependence, and intervention.
   • The problem of scarcity and factors of production (land, labour, capital, and entrepreneurship).
2. Economic Models and Decision-Making:
   • Opportunity cost and the cost of choice.
   • The production possibilities curve (PPC) model, illustrating concepts such as scarcity, choice, efficiency, and growth.
   • The circular flow of income model showing interdependence among households, firms, government, and the foreign sector.
3. How Economists Approach the World:
   • The distinction between positive economics (based on empirical evidence) and normative economics (value-based judgments).
   • Historical perspectives on economic thought, including contributions from Adam Smith, Karl Marx, and Keynesian theory.
   • Modern approaches, including behavioural economics and sustainability-focused models.
4. Critical Thinking and Inquiry:
   • Encourages students to question assumptions and evaluate the applicability of economic models to real-world scenarios.
   • Integration of Theory of Knowledge (TOK) questions, such as the realism of models and ethical implications of economic policies.

Unit 2: Microeconomics

The Microeconomics unit dives into the behaviours of individual consumers, producers, and markets, as well as the forces that shape resource allocation in an economy. It focuses on how resources are distributed to meet the needs and wants of society, the interactions between demand and supply, and the role of government in addressing market failures.

Key Areas of Focus:

1. Demand and Supply:
   • Analysis of the laws of demand and supply.
   • Understanding determinants that cause shifts and movements in demand and supply curves.

Overview of the IB Economics Internal Assessment

The Internal Assessment (IA) in IB Economics is a critical component that allows students to apply their economic knowledge and analytical skills to real-world issues. It involves the creation of a portfolio consisting of three commentaries based on news articles. This component is internally assessed by teachers and externally moderated by the IB.

What Is Involved?

1. Portfolio Creation:
   • Students produce three commentaries.
   • Each commentary is based on a news article that reflects current economic events or policies.
   • Articles must align with different units of the syllabus (excluding Unit 1: Introduction to Economics).
   • A different key concept is used as the analytical lens for each commentary.
2. Article Selection:
   • Articles must be contemporary, published no earlier than one year before the commentary is written.
   • Each article should come from a different source to ensure diversity.
3. Word Limit:
   • Each commentary is limited to a maximum of 800 words, excluding diagrams, labels, and citations.

What Is Being Assessed?

The Internal Assessment evaluates the following skills and competencies:

• ‍Maximum Marks: 45 (14 marks for each commentary + 3 marks for rubric adherence).

Purpose of the IA:

The IA is designed to:

• Foster an understanding of real-world applications of economic theory.
• Develop research, analytical, and evaluation skills.
• Allow students to explore economic issues of personal interest in depth.

Overview of the IB Economics External Assessment

The external assessment for IB Economics evaluates students' ability to understand, apply, and evaluate economic concepts and theories. The assessments are designed differently for Standard Level (SL) and Higher Level (HL) students, reflecting the depth and breadth of their studies.

Structure of External Assessment: SL

Structure of External Assessment: HL

What Is Being Assessed?

The external assessments are aligned with the Assessment Objectives (AOs) of the course, which include:

1. Knowledge and Understanding (AO1): Demonstrating familiarity with economic terms, theories, and concepts.
2. Application and Analysis (AO2): Applying knowledge to explain economic issues and analyse economic problems.
3. Synthesis and Evaluation (AO3): Evaluating economic policies and theories to make reasoned judgments.
4. Use of Skills (AO4): Using quantitative and diagrammatic tools to analyse and communicate effectively.

Linking to Assessment Objectives and Importance

• Paper 1 focuses on extended responses, challenging students to demonstrate AO1, AO2, AO3, and their ability to apply theories critically in real-world contexts.
