| The move towards a revenue-share-based ADC in place of the specific one existing so far has been justified on the grounds that it will reduce arbitrage opportunities of the sort that led to the Reliance Infocomm ADC-avoidance game of switching numbers to disguise overseas calls as local ones. The problem, however, is that the proposed revenue-share system does not apply to international calls, where the ADC is expected to be higher than even the total value of calls. And while it is true that arbitrage opportunity has been reduced, with the ADC on incoming overseas calls being halved from Rs 3.25 a minute, the proportion of grey calls will fall only if Indian firms pass on this reduction to overseas carriers. If the reduction is not passed on, the effective arbitrage remains unchanged and so, logically, should the proportion of grey market calls. The last time the ADC was reduced on international calls, the reduction never got fully passed on and so the grey market didn't decline either. |
| The other area where Trai has displayed a Nelson's eye is that of long distance tariffs. An overseas call from a mobile, for instance, is billed at over Rs 14 a minute today while the cost cannot be more than Rs 4-5 a minute. Clearly the market's not working, and Trai should be addressing the issue. |
