Dear all,
Please join us for the Applied Statistics Workshop (Gov 3009) this
Wednesday, March 28 from 12.00 - 1.30 pm in CGIS Knafel Room 354. Teppei
Yamamoto, Assistant Professor at the Department of Political Science at
MIT, will give a presentation entitled "A Multinomial Response Model for
Varying Choice Sets, with Application to Partially Contested Multiparty
Elections". As always, a light lunch will be provided.
Abstract:
This paper proposes a new multinomial choice model
which explicitly takes
into account variation in choice sets across observations. The proposed
varying choice set logit model relaxes the independence of irrelevant
alternatives assumption by allowing the individual random utility function
to directly depend on choice set types, and can be applied to a variety of
data in which some individuals can only choose from a subset of the
theoretically possible responses. Both frequentist and Bayesian
simulation-based estimation procedures are developed using the Monte Carlo
expectation-maximization algorithm and Markov chain Monte Carlo,
respectively. The proposed model can be used to analyze survey data in
partially contested multiparty elections in which some political parties do
not run their candidates in every district. For illustration, I apply the
proposed method to the 1996 Japanese general election, where none of the
districts was contested by all of the six major parties.
