Yes. One study, in which I did not take part, was led by our lawyer's firm. Confidentiality agreements were in place. Indeed, we noted that the difficulty of passing on regulated price increases to retailers is definitely a big problem.
Furthermore, I must say that a code of conduct won't regulate prices as such. However, cooperation and influence come into play when it's time to establish contractual certainty. Indeed, as I was saying, the intention of the code of conduct is to improve relationships and reduce bureaucracy, fees and arbitrary penalties in favour of contractual certainty. That is what will actually help the industry, rather than regulating sale prices that processors charge retailers.
