Abstract

We show if a speculator can benefit from reducing a monopoly's rents through short selling, then a speculator may take a short position in a monopoly, overcome the barriers to entry, and compete with the monopoly. The competition drives down the monopoly�s rents, and as a result, the short position becomes profitable and covers the cost of entry. If entry is impossible, then the speculator may coordinate and pay the firm�s counter-parties to stop trading with the monopoly rather than entering. Either way, increasing a speculator�s ability to short a firm�s rents results in a constraint on the monopoly and forces it to act more like a price taker. The mechanism is a market based approach to antitrust.
