When one of the major parties in the United States wins a substantially larger share of the seats than its vote share would seem to warrant, the conventional explanation lies in manipulation of maps by the party that controls the redistricting process. Yet this paper uses a unique data set from Florida to demonstrate a common mechanism through which substantial partisan bias can emerge purely f...

We utilize the Cox and Katz (1998, 2002) bargaining model of the redistricting process and data from the 1972-2000 House elections to answer two questions: first, does the creation of majority-minority districts increase the likelihood that minority candidates will be elected in those districts? Second, does the creation of majority-minority districts also generate pro-Republican gerrymanders? ...

Imagine that one could stretch a geographical map so that areas with many people would appear large, and areas with few people would appear small. If such a map could be made one would expect all voting districts to be the same size for they should contain equal numbers of people. Drawing on such maps should simplify the process of creating district boundaries. The construction of maps of the r...

A matheuristic approach that combines a reduced variable neighbourhood search (rVNS) algorithm and mathematical programming (MP) solver to solve novel model for the districting problem in public bicycle-sharing system is presented. The modelled as an integer problem. While rVNS aims find high-quality set of centres repositioning zones, MP computes optimal allocation network stations zones. We u...
