I'm not quite sure I follow what emotional spending is precisely. If it's not living beyond your means, that just seems like pretty sound practical advice. Is it looking for emotional triggers that cause people to spend more than they intend to? If so, there's a couple of good books and presentations out there by behavioral scientists / inter-disciplinarians. Two of my old favorites are: Barry Schwartz (Paradox of Choice) and Dan Ariely (a behavioral economist).
My example:
People who purchase warranties that cost more than the item they want to protect is worth. I noticed this recently when picking up another usb flash stick a while back. The device doesn't have a failure rate that's particularly high and the warranty would expire long before anything wear-n-tear wise would happen. It also didn't cover accidental damage and cost just a few dollars less than the device. By the time I would need to replace it, my device would be worth significantly less for the same amount of storage. The price I paid then would provide more storage for a better device and I couldn't use the warranty to get a newer model if it happened. I guess they were trying to play on some kind of security/comfort need?
