If you look at your experience with the rental markets, why did those work? It's because people wanted the information. It was timely, accurate, and useful. Our current labour market doesn't get many of those ticks as you go along with it. Employers would be willing to participate—certainly the engineering employers—if you've got that same type of information that it was very timely, accurate, and useful to them. You will increase that whole participation in it.
I think that's really the type of model to consider. If you look at those types of systems that provide us regular feedback on other sectors of the economy and how those work, I think those are the types of systems we should modelling our labour market on, so that you get that information.
