Our approach results in a tractable model that provides interesting compara- tive statics on the effect of recent technological advancements. For instance, we can accommodate a new justification behind the well-documented simultaneous increase in campaign spending and polarization: an increase in the effectiveness of electoral advertising, or a decrease in the electorate’s political aware- ness, surely increases polarization and may also increase campaign spending.application/pdfeng2022 The Authors.
