IBDP Economics HL
This AccelaStudy domain covers the full IB Diploma Programme Economics Higher Level syllabus, preparing students for one of the most analytically demanding Group 3 subjects in the IB Diploma. The course is built around four interconnected units — Introduction to Economics, Microeconomics, Macroeconomics, and The Global Economy — and requires students to move fluently between theoretical models, quantitative calculations, diagrammatic analysis, and real-world policy evaluation.At HL, students go significantly beyond the SL content. The microeconomics unit extends into a full theory of the firm, requiring mastery of cost and revenue curve analysis across all four market structures: perfect competition, monopolistic competition, oligopoly, and monopoly. Students must also analyse price discrimination and evaluate competition policy. The macroeconomics unit adds the Keynesian multiplier, the expectations-augmented Phillips curve, and the Laffer curve. The international economics unit extends to terms of trade calculations, the Marshall-Lerner condition, and the J-curve effect. Development economics at HL includes the Harrod-Domar growth model, the Lewis dual-sector model, and institutional economics perspectives.The course is structured around nine key concepts — scarcity, choice, efficiency, equity, economic well-being, sustainability, change, interdependence, and intervention — which serve as integrating lenses across all units and as explicit evaluative criteria in extended responses. Assessment at HL comprises three external papers (Papers 1, 2, and 3) plus three internal assessment commentaries. Paper 3 is HL-exclusive and requires students to synthesise micro and macro theory in response to unseen policy stimuli.AccelaStudy's adaptive engine targets each of the four IB assessment objectives: AO1 knowledge recall, AO2 application and analysis, AO3 synthesis and evaluation, and AO4 diagrammatic and quantitative skills. The platform's contrastive pair engine is particularly effective for economics, where students must distinguish between superficially similar concepts such as movement along versus shift of a curve, nominal versus real values, and trade creation versus trade diversion. Tribunal verdict exercises build the evaluative writing skills essential for high-band Paper 1 and Paper 3 responses.

Who Should Take This
This domain is designed for IB Diploma students studying Economics at Higher Level who want structured, adaptive preparation across all four units and all three external papers. It is ideal for students who find the HL theory of the firm or the quantitative extensions (multiplier, terms of trade, Gini coefficient) challenging, as well as those who want to sharpen their extended-response evaluation skills for Papers 1 and 3. Students considering university study in economics, finance, public policy, international development, or any quantitatively oriented social science will find the HL content directly relevant to first-year university courses. The domain is also suitable for students retaking the IB Economics HL examination who need targeted remediation on specific units or assessment objectives.

1Unit 1: Introduction to Economics 1 topic
Foundations of Economic Thinking
- Define scarcity, choice, and opportunity cost, and explain how these three foundational concepts underpin all economic decision-making by individuals, firms, and governments facing unlimited wants but limited resources.
- Construct a production possibility curve diagram, label its axes and points correctly, and explain how points on, inside, and outside the frontier illustrate productive efficiency, inefficiency, and unattainability respectively.
- Distinguish between positive and normative economic statements, providing examples of each, and explain why this distinction matters for the role of economists in informing public policy debates.
- Evaluate the strengths and limitations of the three main economic systems (market, planned, and mixed economies) in allocating scarce resources, using the nine key concepts of the IB Economics course as evaluative criteria.
2Unit 2: Microeconomics 3 topics
Demand, Supply, and Market Equilibrium

- Calculate price elasticity of demand, income elasticity of demand, and cross-price elasticity of demand from given data, and interpret the sign and magnitude of each coefficient in terms of consumer responsiveness.
- Analyse how price elasticity of demand and price elasticity of supply jointly determine the incidence of an indirect tax between consumers and producers, using consumer and producer surplus diagrams with welfare loss triangles.
- Evaluate the effectiveness of price controls (maximum and minimum prices) as government interventions, using supply and demand diagrams to illustrate shortages, surpluses, and unintended consequences in real-world markets.
Market Failure and Government Intervention
- Explain the concepts of externalities and public goods as sources of market failure, and illustrate negative and positive externalities of production and consumption using marginal social cost and marginal social benefit diagrams.
- Evaluate the relative merits of market-based solutions (carbon taxes, tradeable permits) versus direct regulation in correcting negative externalities, considering efficiency, equity, and practical implementation challenges.
- Explain asymmetric information as a source of market failure, distinguishing between adverse selection and moral hazard, and analyse how these problems affect markets such as insurance, healthcare, and financial services.
Theory of the Firm — HL

- Analyse the profit-maximising output and price for a perfectly competitive firm in both the short run and long run, using MC=MR diagrams, and explain why only normal profit persists in long-run competitive equilibrium.
- Analyse the profit-maximising equilibrium of a monopoly using AR, MR, and MC curves, calculate the deadweight welfare loss triangle, and evaluate the conditions under which monopoly may be preferable to perfect competition.
- Explain the characteristics of monopolistic competition and derive its short-run and long-run equilibrium positions, comparing outcomes with perfect competition and monopoly in terms of efficiency, price, and product variety.
- Evaluate oligopoly models including the kinked demand curve, game theory (prisoners' dilemma), and collusion, assessing the implications of strategic interdependence for pricing behaviour, innovation, and consumer welfare.

- Analyse the short-run and long-run Phillips curve relationship between inflation and unemployment, explain the expectations-augmented Phillips curve, and evaluate the implications of the natural rate of unemployment hypothesis for policy.
- Evaluate the effectiveness of expansionary and contractionary fiscal policy in achieving macroeconomic objectives, considering the role of automatic stabilisers, time lags, crowding out, and the size of the fiscal multiplier.
- Evaluate the effectiveness of monetary policy tools (interest rate changes, quantitative easing, reserve requirements) in achieving price stability and output goals, comparing Keynesian and monetarist perspectives on monetary transmission.
- Analyse the Laffer curve relationship between tax rates and tax revenue, and evaluate supply-side policies (deregulation, privatisation, labour market reforms, investment incentives) as tools for shifting long-run aggregate supply.

- Analyse the welfare effects of a tariff using a supply and demand diagram showing domestic production, imports, consumer surplus, producer surplus, government revenue, and deadweight welfare loss before and after the tariff.
- Evaluate the arguments for and against protectionist trade policies (infant industry, strategic trade policy, national security, anti-dumping), assessing their economic validity and the risks of retaliatory trade wars.
- Analyse the concepts of terms of trade and the Marshall-Lerner condition, and explain the J-curve effect to show how a currency depreciation may initially worsen before improving a country's current account balance.
Exchange Rates and the Balance of Payments
- Explain the determination of exchange rates under floating and managed exchange rate systems, identify the factors that cause exchange rate fluctuations, and construct supply and demand diagrams for a currency market.
- Analyse the components of the balance of payments (current account, capital account, financial account), explain how a current account deficit is financed, and evaluate the significance of persistent current account imbalances.
