The effects that regulation has on the innovation and the introduction of new telecommunications services have not been previously quantified in the literature. This study compares state-regulated services in Indiana under rate of return regulation (RoRR) and under alternative regulation. The econometric model comprises an count process (for innovation) followed by a duration process with selection (for regulatory delay). Moving away from RoRR increased the rate of service creation to three times the old rate. Expected approval delays nearly disappear. A prediction exercise indicates that the firm would have introduced 12 times as many services to consumers if the alternative regulation had been in place the entire time.
