My response to incessant complaints in the region about profits disappearing and investment drying up because of excessive licensing has been to say that liberal and transparent market entry policies must be accompanied by clearly stated exit policies that are consistently enforced. I have also pointed out that in many South Asian markets the levels of competition, as measured by the HHI, are relatively higher than in the US and that what applies in S Asian markets does not necessarily apply in N American markets and vice versa. In this light, it is worth tracking what happens to the AT&T acquisition of T Mobile. AT&T customers, though, could benefit in one notable area: service. Both AT&T and T-Mobile operate on the same technology, known as GSM, so the combination should provide better coverage.
