Economics CT Lessons

Supply-demand models are abstractions. Budget planning uses decomposition. Decision trees drive market choices. CT gives economics students a powerful analytical vocabulary.

Why CT in Economics?

Economic models are deliberate abstractions of reality. Budget planning is decomposition. Price prediction requires pattern recognition. CT helps students see that economics is already computational — and that computers are increasingly running the world's markets.

Supply & Demand as an Abstraction

Students build a simple supply-demand model in a spreadsheet, varying price and quantity, discovering that the model is a deliberate simplification (abstraction) of real markets.

AbstractionAlgorithmic
Learning Objective

Students will build and interrogate a supply-demand model, understanding what it deliberately ignores and why those omissions make it useful.

Activity Steps
  1. Introduce the demand curve: as price rises, quantity demanded falls — but why?
  2. Students create a spreadsheet with Price (₹10 to ₹100) and Quantity Demanded (calculated by formula).
  3. Add the supply curve on the same chart.
  4. Find the equilibrium point: where do the curves intersect?
  5. Ask: what does this model not capture? (consumer psychology, advertising, weather, monopoly) — that's deliberate abstraction.

Family Budget Planner — Decomposition in Personal Finance

Students plan a ₹30,000/month household budget, breaking expenses into categories and sub-categories — discovering hierarchical decomposition.

DecompositionAlgorithmic
Learning Objective

Students will decompose a household budget into hierarchical categories and apply algorithmic decision rules to manage trade-offs.

Activity Steps
  1. Present scenario: a family of 4 earns ₹30,000/month in a Tier-2 city.
  2. Students brainstorm all expenses (food, rent, school fees, transport, savings, entertainment).
  3. Group into categories and sub-categories — this is hierarchical decomposition.
  4. Apply a rule: savings must be ≥ 10%. Adjust other categories until the budget balances.
  5. Introduce a shock: unexpected medical expense of ₹5,000. How does the algorithm adapt?
Duration & Materials

50 minutes · Budget worksheet, calculator, category cards.

💡 This activity has high personal relevance — many students will recognise their own family's budget challenges.
CT Vocabulary

Key CT Concepts in Economics

The core CT pillars illustrated with subject-specific examples from your classroom.

Abstraction
A simplified model that captures the essential dynamics of a complex system.
The supply-demand curve — it models price and quantity while ignoring brand loyalty, social influence, and seasonal trends.
Decomposition
Breaking a complex financial plan into manageable categories.
A household budget broken into food, housing, transport, savings — each a sub-problem with its own constraints.
Algorithm
A decision rule that can be applied consistently to produce a fair outcome.
A budget balancing algorithm: IF savings < 10% THEN reduce entertainment by the shortfall.
Pattern Recognition
Identifying trends in economic data.
Noticing that petrol prices rise before Diwali every year — a seasonal demand pattern that traders exploit.
