These five graphs are extracted from a CD-ROM which supports the Blanchard textbook. Each graph combines an interactive graph with explanatory text. The topics are "Curves, which way do they shift?" "Adjacent or Stacked Graphs," "Real versus Nominal GDP," "The determination of equilibrium income" and "Introduction to Econometrics".

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 3x3 game, binomial tree) and financial theory (e.g. net present value, price-yield curve). Submitted by various authors in Mathematica, with short explanation of underlying theory, and options to manipulate the diagram by changing the different variables. To do this, and view the demonstrations in the browser, requires download of the Mathematica Player browser plug-in which is available for Windows, Linux or Mac. These form part of the Wolfram Demonstrations Project, hosted on the website of independent scientist Stephen Wolfram as a development of his popular Mathematica program.
Presents a new, causal representation of macroeconomic models as graphs which enable explanation, interpretation and analysis. The method is explained and illustrated with examples of static and dynamic models. There are freely downloadable chapters from the book "Macroeconomic Models in a Causal Framework" by Geoffrey J. Wyatt, En Exempla Books, Edinburgh 2005 (ISBN 0954620216) and a freely accessible Java program for flowgraph modelling in a web-page.
