I’m observing this debate but want to point some things out to our new Keynesian that needs be said:
economically, coercion is any action or threat of action to transfer/violate someone’s property rights without their consent. This includes the product of slave labor - labor compelled under threat of violence. Mobs stealing from big business is just as coercive as governments demanding taxes or mobsters demanding “protection” revenues.
That being said, a free market is not the basis of our argument. a free market is utopian. what we advocate is a system that encourages coercion to the smallest degree possible. this means no government, or minimal government coercion. it also means a strong attempt to establish justice where coercion does take place. arguing “that wasn’t a free market” is not an excuse we can make, as there has never been one and probably won’t be a sustained one, ever. however, we can argue that tolerance of and support for systems that involve coercion are economically backward.
in regards to the scientific method, microeconomic experiments are flawed if the “subjects” know they are being watched, which must be the case to create a controlled experiment. in macroeconomics, empirical data can never be entirely accurate. There may be a certain form of pertinent information which is simply not collected, or collected incorrectly. And to the effect that individuals still know they are being observed, they will act differently. This is why social sciences take the approach of logical deduction from a priori axioms that are undebateably true.
your mexico example with Mr Slim and Telmex is slightly absurd. Telmex was a nationalized monopoly for decades. For the first 7 years of being privately owned by Slim, it was given a state-granted monopoly. Even after this, it was not open to foreign investment for local phone service. Slim’s buying price was artificially low as it was poorly run, as all government enterprises are. Once Slim put market equillibrium prices into effect, revenues soared and the value of the company went up greatly. Thus, he was pretty much offered several state subsidies. His market share IS decreasing, as Telmex is obviously run uncompetitively, as most monopolies are. But the idea that this arose from an unregulated or state-subsidized market is out there.
DeBeers is surely coercive or in collusion with coercive forces, not necessarily a government. Think warlords with slave armies given primitive tools to dig up diamonds. As far as de facto monopolies (not necessarily free market monopolies, but ones not explicitly granted by government), DeBeers is the only one I’ve heard of in all of history. I would agree, however, that it is a de facto monopoly. Free market monopoly, no.
As far as using economics or coercive elements to control the media, it seems the monopoly of government ALWAYS has more resources, which the public generally accepts, at doing just that. so the information problem isn’t a problem of the market as much as it is one of society in general. and if a competitive company can outcompete the big dog, it’d make little sense for media outlets to exclude their advertisements, as they are losing potential revenue. media outlets would make more money from dozens of small companies’ advertisements then from one monopoly’s suppression of such advertisements. the only way this could be false is if the monopoly offered better service at better prices than competitors. hence, a natural monopoly, which benefits consumers and the monopoly producer.
let’s ditch the nuke and pathology arguments. they are less about economy than safety. i would agree they could occur in any setting.
