I recommend UNCTAD's report: E-COMMERCE AND DEVELOPMENT REPORT 2003.
The report has a very interesting discussion of international trade in coffee and tea, suggesting that while terms of trade have deteriorated for developing country exporters of these commodities, and online markets have done little to stop the trend, there may be some hope in online auctions of high quality goods.
There is also a discussion of free and open source software, which I would not have expected in a book of this title.
