  • Elasticity of Demand

    Example: Graph: Key Insight: Elasticity helps businesses decide pricing strategies.

  • Market Equilibrium

    Example: Graph: Key Insight: Free markets naturally move toward equilibrium.

  • Law of Supply

    Example: Graph: Key Insight: Producers respond positively to price increases.

  • Law of Demand

    Example: Graph: Key Insight: Demand curves always slope downward due to inverse relationship between price and demand.

  • Parable of the Polygons

    Vi Hart; Nicky Case A well-designed interactive web page, with succinct text and a succession of playable cartoon simulations, explains Nobel Prize-winner Thomas Schelling’s work on dynamic models of segregation. It uses animated shapes rather than people, and users can introduce different preferences to the characters and see the results.

  • Economics demonstrations

    Wolfram Demonstrations Project Graphic representations of various concepts in microeconomics (e.g. monopoly, consumer and producer surplus, Edgeworth Box), macroeconomics (e.g. Solow growth model, Keynesian cross, Lorenz Curve and Gini coefficient), game theory (e.g. Nash equilibrium in 3×3 game, binomial tree) and financial theory (e.g. net present value, price-yield curve). Submitted by various authors in Mathematica,…

  • DIY Model Simulation

    Franz Prante, Chemnitz University of Technology & Karsten Kohler, University of Leeds Open source repository of common macroeconomic models in the R language. Each page describes and spells out the model, provides example code for numerical simulations, and illustrative output and analysis. The approach is spelled out in a “How to simulate economic models” section.…

  • Jo-Lou

    More than twenty interactive workbooks for Microeconomics, Macroeconomics and Econometrics, created using the Wolfram programming language. Each chart illustrates a concept or model, and gives many parameters that the reader can adjust to see the resulting changes. The interactive workbooks can be viewed online or downloaded to the reader’s computer to run in the free…

  • Creating spreadsheets

    Ten Excel spreadsheets, each with a worksheet in Microsoft Word format, are held here. Each spreadsheet takes several different inputs from the student and the worksheets give specific guidance on how to use them. Topics are: Working with Lines, Market Equilibrium, Market with tax, Cardinal Utility, Consumer Choice, Income and Substitution Effects, Products and Costs,…
