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.
Consumption and Households in Financial Economics
PowerPoint presentation depicting decision-making under risk, showing how risk attitudes can be examined using choices among lotteries or willingness to pay for insurances. Shows how risk attitudes can be captured in convexity of the indifference curve or strict concavity of the utility function; and how risk aversion can be quantified by the ratio of second and first derivatives of the utility function, implying that it falls as wealth increases.
