배타적 면허권자가 있는 경우 주파수 공유방식의 사회후생비교

초록

This study considers two alternative governance regimes on spectrum sharing with property rights holder(s): One is free contract regime in which the property rights holder chooses whom to share and how much to charge for sharing, the other is non-interference open access regime in which anyone can share the spectrum as long as he(she) does not interfere the use by the property rights holder. The services provided by the sharing firms are differentiated from the service by the property rights holder. We presents a theoretical framework that allows to evaluate the welfare consequences of two alternative regimes and performs a simulation with specific numerical values for supply and demand parameters. The relative performances of two alternative regimes depend on the substitution of two services and the number of property rights holders. Free contract regime is more likely to outperform non-interference open access regime when the more differentiated are the two services and there are two property rights holders rather than one.
