Description:

Preferences and Indifference Curves - animations and detailed audio explanations. Covers various standard assumptions about preferences, how these assumptions translate into indifference curves. In part B, 3 dimensional utility functions are used to motivate an intuitive connection between utility and the normal 2 dimensional drawings used in Intermediate Micro.

This app is designed to be of value for any intermediate micro economics student studying indifference curves their derivation from preferences. First year grad students may also find this material a useful review. This app contains 9 animated graphs with voice overs that explain the relevant 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 sufficiently thorough that listening without viewing the graph is also very instructive.

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.
