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.
Interactive Tutorials in Intermediate Microeconomics
A set of configurable, graphically appealing, online interactive games that work across laptops, iOS (Apple) and Android devices. Instructors can customise the games, or use default settings, and students join by entering a class code. The instructor gets a graphical analysis of outcomes immediately at the end of the session, for use in class discussion. The site has course guides that suggest how to sequence the games in different Economics courses, and each game has references to relevant papers. The site's apps can also be used to administer individual survey or assessment questions online.
"This interactive simulation visualizes the welfare implications of different approaches to connect buyers and sellers of a good. The user can act as a perfectly informed social planner, as a partially informed social planner, or she can elicit bids/ask offers from simulated agents in a double auction setting. The resulting allocations with the implied consumer and producer surpluses are visualized. The user experiences the informational demands that a social planner faces, and she observes the ability of a price system to allocate scarce resources when information is largely private, even if individual market participants are not sophisticated." - description quoted from The Journal of Economic Education, v46 n4 DOI: 10.1080/00220485.2015.1071215
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, Competitive Firm, Competitive Industry, and Monopoly.
