Walu,
Point noted.
Going by the market shares, there is no significant difference between "the market" and "Safaricom" from where I sit. The dominance becomes more
explicit as you move from data to voice to mobile money services. I subscribe to the naive notion that by fixing Safaricoms shortcomings, you are sincerely addressing the market failures. This is because other firms in an industry tend to emulate their apparently "successful" brother. If the firstborn is allowed to run amok, the siblings will also become rogue as they grow up.
Alternatively if we say that we fix market failures, its not sufficient to stop there. Let's demystify the term and highlight specific mechanisms of dealing with the failures head on.
