I'd love to see the data, but knowing Amazon they have both extensively tested it and will not release the findings. Anecdotally I have never not purchased something because I had to set the cursor focus and I have purchased something I saw on the home page. Also, if you're a nerd, just search right in the browser. If I want to search Amazon I never actually go Amazon first I just type "a", hit tab and then my search terms. Chrome is smart enough to do the rest and I get right to the SERP on Amazon.
