Buenos Aires

This paper presents the first study on the impact of different voting technologies on election outcomes in multi-party elections, analyzing data from a large-scale voting experiment conducted in the 2005 congressional election in Buenos Aires, Argentina. Combining different regression models and matching methods, we estimate the effect of alternative voting technologies on the probability of support for the competing parties in the elections for congress and state legislature.

The Buenos Aires “VotoElectronico” pilot project took place on October 23, 2005, in the City of Buenos Aires. It involved a pilot test of four different electronic voting systems, in at least 43 voting stations located throughout the City. The purpose of this report is to provide initial qualitative assessments of the pilot project. Quantitative analysis will hopefully be presented at a later date, once detailed data from the pilot project are available for examination.
