Interactive Tutorials in Consumption and Households
Interactive view of social mobility data for the United States. Two dozen different outcomes can be analysed, and the results segmented by gender, race and native/immigrant as well as geographically. The site has built-in tutorials, downloadable data and the ability to upload and overlay your own data. There is a permalink feature that allows you to bookmark and share the exact state of the map you are looking at. The "stories" function shows how the data have been used to reach specific research conclusions. In Advanced Mode, it is possible to filter for specific ranges of values.
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.
