Abstract

In a common-values election with two candidates voters receive a signal about which candidate is superior. They can acquire information that improves the precision of the signal. Electors differ in their information acquisition costs. For large electorates a non negligible fraction of voters acquires information, but the quantity of informed voters and the quality of acquired information decline so fast that information aggregation fails to obtain.
