The driving factor behind the development of offshore outsourcing has been the need to cut costs while the enabling factor has been the global electronic internet network that allows digital data to be accessed and delivered instantly, from and to almost anywhere in the world.
The widespread use and availability of the Internet has enabled individuals and small businesses to contract freelancers from all over the world to get projects done at a lower cost due to lower wages and property prices. Crowdsourcing systems such as Mechanical Turk have added the element of scalability, allowing businesses to outsource information tasks across the Internet to thousands of workers.
This trend runs in parallel with the tendency towards outsourcing in larger corporations, and may serve to strengthen small business' capacity to compete with their larger competitors capable of setting up offshore locations, or of arriving at major contracts with offshore companies. See Freelancing on the Internet.
One issue offshoring of technical services has brought more attention to is the value of education as an alleged solution to trade-related displacements. Education may no longer be a comparative advantage of high-wage nations because the cost of education may be lower in the nations involved in the controversy.
While it is true that education is usually considered helpful to competitiveness in general, an "education arms race" with low-wage nations may not pay off.
For a new topic, outsourcing has produced a huge volume of research, not all of it worthwhile. Here is a sprinkling of some of the better stuff:
