Reports of Uber-Grab regional deal 'speculation'

Click HERE

Uber vs Grab -- a good example of competition.....and possibly impending cooperation when the two merge....already, each is cooperating with other groups (e.g. Confort Delgro) to have an edge over the other; a case of cooperate in order to compete...
Note that their competition with each other benefits consumers in the form of discounts....but both are making losses in the bid to win a bigger market share by offering steep discounts...
Competition also forces them to innovate -- using apps and other technology to better serve customers more efficiently ....

Qns:

1. Is competition always desirable? (Cam. 2016)

2. "Cooperation, not competition, is the key to success." Discuss.
