Why would consumers pay more for separate than bundled products?

A study by Aaron R. Brough and Alexander Chernev found that consumers tend to perceive bundled products as 'moderately expensive', leading them to pay less. The authors suggest that managers should sell items from different price tiers separately to maximize revenue.
