On the first one, again, I don't want to put myself forward as an expert on how to clean a house or a property, but certainly if you're going to compare estimates for the costs of a service, you want to make sure that you're comparing apples to apples. It strikes me that the difficulty, if you have a high standard being imposed by the government on maintenance or on cleaning, and a lower standard in the private sector as they alleged, then you are going to have different costs. One of the reasons the cost may be different is the choice of different standards. If you're trying to make a comparison or draw inferences from that, I think your comment is quite appropriate, that you'd better make sure you know that what you're buying is day-old bread rather than fresh bread, just to use that analogy.
In terms of the second one, I wasn't quite clear on what you were trying to get as a question. But certainly if you are involved in markets, in spite of the economists' assumptions of perfect information always being available and people being able to make informed decisions, the practice of people in markets is obviously to try to hold onto the information they have. The value of that information is repeatedly used in subsequent transactions. So the incentives are not to be open, but rather to hold information quite tightly. That's generally speaking in markets, and that's why we have regulatory frameworks, to try to make sure that doesn't persist.
