Exclusion through speculation

We demonstrate how an incumbent producer of commodities can use cash-settled derivatives contracts to deter entry and extract rents from a potential competitor. By selling more derivatives than total demand, the producer commits to low prices and forces the entrant to price low upon entry. By setting a high upfront derivatives price, the producer can extract the consumer's gains from those low prices. This exclusionary scheme becomes more difficult when the buyer becomes more risk averse and with multiple buyers.
