Title:        Peer Grading and Mechanism Design

Abstract:
The first part of the talk will overview a peer grading system that is
under development at Northwestern U.  In courses that use the system it has
(a) reduced the grading load of course staff by over 75%, (b) expanded and
improved the students’ interaction with the course material, (c) and
improved turn-around time of feedback on student work (students receive
comments on their work after three days, rather than two weeks).  As a
research platform, this system enables a dialogue between theory and
practice for algorithms, machine learning, and mechanism design.

Of particular focus for the talk is a connection between incentivizing
students to give accurate peer reviews and all-pay position auctions.
All-pay auctions are a common model for competitions based on effort.  In
an all-pay position auction, bidders compete for positions, where higher
positions are more valuable, and all bidders pay their bids (i.e., their
effort is spent).  The equilibrium outcome of an all-pay auction depends on
the relative values of the positions.  The second part of the talk will
describe recent work on reoptimizing all-pay position auctions from their
equilibrium bid data.

The second part of the talk is joint work with Shuchi Chawla and Denis
Nekipelov.
