Staging... worth it?

[James R. Copeland]

So I'm selling a house in Vancouver for around 560-600k. Many in my family have snubbed their nose at staging, but I've stubbornly insisted on getting staging for the place before photographing and listing it. I'm curious if anyone has done any studies or really gone in depth to study whether or not professional staging has been shown to return more bids and higher bids on their sold houses. Any idea?
