There are a few different objectives there. The first is, again, to collaborate with parties outside the CRA to help them push people in the same direction. I think of cross-communication as an example.
The second is to better understand the behaviours and motivations of people participating in the underground economy so that we can leverage those. In other words, we don't want to continuously increase the number of auditors and audit more and more businesses. Rather, we want to seek to influence people's behaviour, and by understanding the motivations and drivers we can better do that.
Third, in contemplating new measures we want to be careful that we don't impose an undue burden on businesses, particularly small businesses. We think that by talking to experts we can be better informed.
Finally I would just add, nudge theory has gained a lot of prominence in the U.K., and in Canada now. We're starting to build specialized units around nudge, so we have academics participating in the committee, kind of giving us the latest science around modifying people's behaviours.
