For a particular niche in demand but broad in utility industry, I am both a consumer and producer that participates internationally. Within segments of the participants, there are public informal concerns that the elimination of a price floor policy would lead to market failure through the unregulated undercutting of competition that would lead to lower quality products for consumers and an unprecedented drop in the number of competitors. For more sophisticated alternatives, as citizens of a country where free speech is protected, it seems like the people involved should have the right to publicly discuss how a policy would impact their lives and what could be proposed in place of it. However, such discussions would also inevitably include other independent business owners. Because of that, one should keep in mind that it is also strictly illegal for people who own or manage businesses in the same industry to decide or discuss what prices to set for the industry, which makes sense for the purposes of preventing a monopoly or oligopoly.
But, considering that such discussions wouldn't be solely to the benefit of the parties who would discuss such matters, but rather to the health of the entire market for any and all current and future participants, it seems unreasonable that participants who happen to be competitors wouldn't have any way to publicly voice the effects and alternatives of policies without it being considered collusion.
Are there any laws detailing what the limits are in this context? Are there referable precedents for what is allowed and not allowed within the context of maintaining market competition? From what I gather, there is a form of tacit collusion if it would be called that which seems permissible, but I have never had any particular desire for this kind of discussion until recently, so I don't have much experience in knowing how I establish what is legal and what isn't. I am looking for laws that can illustrate details and limits to these discussions to make there are no infringements before proceeding with a quantitative analysis.
