STICERD Economic Theory Seminars

Stochastically Quadratic

Collin Raymond (Oxford University), joint with Chris Chambers and Yusufcan Masatlioglu

Thursday 18 June 2020 15:30 - 17:00

This event will take place online.

Many of our seminars and public events this year will continue as online seminars or as online and in person. Please check our website listings and Twitter feed @STICERD_LSE for updates.

Unless otherwise specified, current restrictions mean in-person seminars are only open to members of the LSE community (those with a valid LSE ID card).

Those unable to join the seminars in-person are welcome to participate via zoom.


About this event

We provide a model of stochastic choice where the choice function is the outcome of an optimization procedure with respect to a quadratic loss function. Although choice probabilities are the result of deliberate randomization, our model is still a random utility model, thus combining two major approaches to stochastic choice. We show that the model is characterized by three simple axioms, and that parameters map to choice probabilities in a transparent fashion. Our model generalizes the Luce model, can accommodate many well known violations of strong stochastic transitivity, and unlike more general forms of random utility, it is uniquely identified.

Economic Theory Seminars are held on Thursdays in term time at 15:30-17:00, ONLINE or ONLINE AND IN PERSON at the same time.

Seminar organisers: Dr Andrew Ellis and Dr Francesco Nava.
