The Borda rule is also intended for dishonest men

This paper examines the welfare consequences of strategic voting under the Borda rule in a comparison of utilitarian efficiencies in simulated voting games under two behavioural assumptions: expected utility-maximising behaviour and sincere behaviour. Utilitarian efficiency is higher in the former than in the latter. Strategic voting increases utilitarian efficiency particularly if the distribution of preference intensities correlates with voter types. The Borda rule is shown to have two advantages: strategic voting is beneficial even if some but not all voter types engage in strategic behaviour, and even if the voters’ information is based on unreliable signals.
