Thank you.
This is a question that has always been of interest to economists in general. Of course, from a central bank's point of view almost anything like that is of interest.
However, it's of interest from the point of view of understanding how the economy is behaving better than we would know without understanding that. We'll do research on a wide range of things that appear to be peripheral to the actual decisions we make, which is not unusual, but they help us have a better feeling of confidence around those discussions.
The bank has a crack research team, it's really superb, and this has always has been one of our trademarks, if you like, of excellence in research.
This could be of interest, mainly if it were getting larger or smaller. It has a connection to the currency business, which I talked about in my opening remarks. It helps us understand whether our currency design and our program is in some way making it easier or harder, but that's really the crack in the door, if you like, the angle with which it has a direct link to us.
