More evidence of the effects of voting technology on election outcomes

Using two different data sources-municipal level data and individual data-we consider several hitherto unexplored aspects of the relationship between voting technology and election outcomes. We distinguish between introductory and permanent effects of electronic voting, and between national and municipal elections. We test for a possible asymmetry between the effect of moving from paper ballots to electronic voting, and vice versa, and we control for polling station density. We find a positive but temporary effect of electronic voting on voter turnout, a negative effect on the fraction of residual votes, and no effect on the share of left wing parties.
