Regulation and the Option to Delay
This paper examines a simple two-period model of an investment decision in a network industry characterized by demand uncertainty, economies of scale and sunk costs. In the absence of regulation we identify the minimum price that an unregulated monopolist demands to bear the demand uncertainty and invest early, that is, the price that incorporates the value of the option to delay. In a regulated environment, we show that in the absence of downstream competition and when the regulator cannot commit to ex-post demand contingent prices, a regulated price that incorporates the option to delay is the minimum price that ensures early investment. Furthermore, when the regulator has a preference for early investment, the option to delay price generates higher welfare than other forms of price regulation. We also show that when the vertically integrated network provider is required to provide access to downstream competitors, and the potential entrant is less efficient than the incumbent, an access price that incorporates the option to delay generates the same investment level output as and higher overall welfare than an unregulated industry that is not required to provide access. By contrast, under the same market conditions an ECPR-based access price generates the same overall welfare than an unregulated industry. Moreover, when the potential entrant is more efficient than the incumbent, an Option to Delay Pricing Rule generates the same investment level output as and (weakly) higher overall welfare than the Efficient Component Pricing Rule (ECPR). In addition, the option-to-delay-based access price is (weakly) lower than the ECPR-based access price.
