The standard IB data booklet lists equations, but it lacks the contextual nuance required for swift application. A "repack" reorganizes these tools by logical economic relationships rather than isolated syllabus chapters. This methodology allows you to:
Microeconomics heavily relies on calculating elasticities, costs, revenues, and market efficiencies. Memorizing these structures helps you quickly solve Paper 3 quantitative prompts. 1.1 Elasticities
) apply universally across demand, inflation, and economic growth tracking.
When governments impose tariffs or quotas, you must calculate the resulting changes in quantities, consumer expenditures, and government revenues. ib economics hl formula booklet repack

The bulk of your HL-specific math lives here. You must be able to calculate and interpret elasticities and firm costs with precision. : PED/PES/YED : All follow the format of Interpretation : If , demand is elastic; if , it is inelastic. Costs and Revenues : Total Cost (TC) : Profit Maximization : Occurs where Efficiency : Allocative efficiency is ), and productive efficiency is 2. Macroeconomics: Measuring the Economy The standard IB data booklet lists equations, but
I’ve grouped them by syllabus section.
[ \Delta Y = k \times \Delta G = \frac11 - 0.8 \times 1\ \textbillion = 5 \times 1\ \textbillion = 5\ \textbillion ]
Macroeconomic calculations focus on measuring economic activity, inflation, and the multiplier effect. GDP (Expenditure Approach) : GNI (Gross National Income) : Real GDP : Inflation and Employment Inflation Rate : Unemployment Rate : The Keynesian Multiplier Marginal Propensity to Consume (MPC) : Keynesian Multiplier ( ) : 3. The Global Economy (Unit 4) Memorizing these structures helps you quickly solve Paper
Learn from the mistakes others make. Don't just write the final answer—always show your steps. Don't forget negative signs for PED and XED. Always include units. By avoiding these common pitfalls, you will gain an edge over many of your peers.
The is a consolidated reference tool designed to support students through the quantitative demands of the Higher Level (HL) syllabus, specifically for Paper 3 (the "Policy Paper"). While the official IB does not provide a comprehensive "formula sheet" for use during exams, these repacks serve as essential study aids to centralize the equations scattered across the Microeconomics, Macroeconomics, and Global Economy units. Core Content Structure
This section covers the behavior of individual economic agents—consumers, firms, and markets. It’s heavy on elasticity, costs, revenues, and market structures. Here’s how to repack it.
This is a often tested in Paper 3. The multiplier measures how an initial change in spending leads to a larger final change in national income.
