Very intersting question, Andy. I am sending some articles and links that might provide a point of departure.

Thanks so much, Frank.  The Egyptian case looks very interesting and I will read it carefully.  The others are good food for thought, and show just how profound and unpredictable the internet's economic effects will be.  I will keep looking....

Dear Andy Hira

Greetings,

Please find the two attached files , about sharing economy  related to your topic may be useful for you .

Best Regards, 

As information is the currency of the sharing economy, the slower rate of participation in the sharing economy may be explained by the slower rollout of access-enabling technologies. Institutional bottlenecks and regulatory gridlocks are prevalent. Resulting in heterogeneous access to public media in Asia (2012):

Discounting infrastructure challenges and slow rollout, there are cultural obstacles as well. Whether this is a response to the prevailing regulatory climate is unsure. Knowledge sharing in IP intensive firms in the South-East Asian context seems to be hampered by the lack of an "organizational learning environment", where employees are not expected to be "performers":

Thanks for your responses, Faris and Shian-Loong.  The documents are not really what I am looking for, which is a case study of a sharing economy company in the developing world, but they are generally interesting.  I take your point, Shian-Loong, that access to internet services will be uneven.  I suppose the most famous response is m-pesa in Kenya, which relies upon mobile phones, whose price, as you know, has come down quite a bit in price.  M-pesa allows them to conduct financial transactions in very small increments electronically, which is much more inclusive than the formal banking sector.
