Do consumers do more research before making an expensive purchase than before making a cheaper purchase?

It stands to reason that a consumer will spend more time researching something that involves a greater investment as opposed to something that will cost them less. I am looking for some research that backs this up.





Please provide a link to a Source with your answer. Thanks!
