The problem is the working environment in general, doesn't matter if it's at home or in an office, if the surrounding environment is full of distractions then productivity will be as bad everywhere. For a knowledge worker where they need to concentrate there needs to be a quiet distraction free environment without interruptions. If this is at home in a separate low-traffic room or in an office with few people and a door that can be closed , both will work well. However I don't think many people's environments are like that in either place. So to me there's no difference between working at home or the office, if you're going to have people interrupting you, high levels of background noise, and other visual/scheduling distractions.
