초록

The spectrum charges for the 3G mobile telecommunications were 1.3 trillion won for each operator, and the charges were fixed at 3 percent level of the expected service revenues. When there exists uncertainty in service demand, however, the fixed-fee spectrum charges may cause economic inefficiencies: The optimal structure of spectrum charges in this environment consist of the fixed fee and the royalties dependent on actual revenues. This paper builds an operational model to estimate the amount of fixed fee and the royalties of the spectrum charges. When demand uncertainty is large so that the expected revenues under the pessimistic prospect lie between 7 to 10 trillion won, the royalties of 1.1% to 1.8% of the actual revenues need to be charged under the optimal structure of spectrum charges if the government wishes to collect 1.3 trillion won on average. The fixed fee in this case amounts to 45% to 65% of the total spectrum charges.
