SUMMARY:Simultaneous elections make single-party sweeps more likely
LOCATION:Hill 705
DESCRIPTION:Date: 04/02/2025Speaker: Siddhartha Sahi (https://sites.math.rutgers.edu/~s
ahi/) (Rutgers)\nTitle: Simultaneous elections make single-party sweeps mor
e likely\nAbstract: In a country with multiple elections, it may prove econ
omically expedient to hold some or all of them on a common polling date. We
show that such a decision will bring about a systemic change at the politi
cal level; an increase in the simultaneity of polling increases the likeli
hood that a single party wins all the elections.\nOur result holds under f
airly general conditions and we discuss its applicability to the two most c
ommon real world electoral systems, namely "first-past-the-post" (most vote
rs) and "party list proportional representation" (most countries). In the c
ourse of our analysis, we obtain a slight generalization of the Harris corr
elation inequality for monotone functions on the Boolean lattice.\nThis is
joint work with Pradeep Dubey (Center for Game Theory, Stony Brook).\nThe t
alk will be elementary, self-contained, and suitable for a general audience

Title: Simultaneous elections make single-par
ty sweeps more likely
Abstract: In a co
untry with multiple elections, it may prove economically expedient to hold
some or all of them on a common polling date. We show that such a decision
will bring about a systemic change at the political level; an increas
e in the simultaneity of polling increases the likelihood that a sing
le party wins all the elections.
Our result holds under fairly general conditions and we discuss its
applicability to the two most common real world electoral systems, namely
"first-past-the-post" (most voters) and "party list proportional representa
tion" (most countries). In the course of our analysis, we obtain a slight g
eneralization of the Harris correlation inequality for monotone functions o
n the Boolean lattice.
Th
is is joint work with Pradeep Dubey (Center for Game Theory, Stony Brook).<
