Preferences and Indifference Curves - animations and detailed audio explanations. Covers various standard assumptions about preferences, how these assumptions translate into indifference curves. In the part B graphs 3 dimensional utility functions are shown.

This app is designed to be of value for any intermediate micro economics student studying indifference curves and how they are derived from tastes/preferences. First year grad students may find this material a useful review. It contains 9 animated graphs with voice overs that explain the graphs and topics in detail as the graphs unfold. The animations allow the user to see each graph created from beginning to end as Professor Nechyba's audio explains the economic concepts being illustrate.

User can jump to whichever graph or portion of a graph is of interest or play through each graph in its entirety while listening to the accompanying audio. In most cases the audio is so thorough that listening without viewing the graph will provide great benefit too.

This app is based on Chapter 4 of _Microeconomics, An Intuitive Approach with Calculus_, 2nd Edition by Thomas J. Nechyba, Department of Economics, Duke University, Durham, NC and developed in conjunction with Professor Nechyba for the Duke University Department of Economics Micro Economics curriculum.
