When technology changes rapidly, outsourcing looks more attractive.
The “make or buy” decision has been a staple of industrial economics as far back as the start of the Industrial Revolution. So when perceived levels of outsourcing began to rise around the world over the past decade or two, researchers began to ask why.
One reason might be the speed of technological innovation during that period. According to Outsourcing and Technological Innovations: A Firm-Level Analysis, a March 2008 working paper: “As the pace of innovations in production technology increases, the firm has less time to amortize the sunk costs associated with purchasing the new technologies. This makes producing in-house with the latest technologies relatively more expensive than outsourcing.” Thus, for example, periods of rapid innovation could result in new or shorter-lived manufacturing robots that only specialist suppliers can justify acquiring.
The paper’s authors — Ann P. Bartel, the A. Barton Hepburn Professor of Economics at Columbia University’s Graduate School of Business, Saul Lach, associate professor in the economics department at The Hebrew University of Jerusalem, and Nachum Sicherman, professor of economics and finance at Columbia’s Graduate School of Business — studied Spanish manufacturers from 1990 through 2002 and concluded that outsourcing does increase with technological change. Using the Encuesta sobre Estrategias Empresariales, an annual survey of Spanish manufacturing companies, for the years 1990, 1994, 1998 and 2002, the researchers examined responses to whether the companies outsourced the manufacture of custom-made finished products or parts and, if so, the value of the outsourced items purchased. The number of respondents ranged from 1,708 in 2002 to 2,189 in 1990.
The researchers also had access to financial data on each company’s research and development intensity (its spending on R&D, if any, as a percentage of revenues), which they used as a proxy for technological change. After all, companies that invest in research and development clearly expect innovation and technological change to be part of the business environment.
The data confirmed that spending on research and development is linked to outsourcing. Overall, the percentage of companies that reported outsourcing rose from 35% in 1990 to 43% in 2002, confirming the impression that outsourcing in general has risen in recent years. And companies with R&D spending were between 6% and 10% more likely to out-source than those that did not choose to invest in R&D. This relationship remained robust even when controlling for factors such as capacity utilization, work force size and costs, the age of the company and product market volatility.
To be sure, there may be other reasons behind the link between technological change and outsourcing apart from the various innovations that companies buy from their parts suppliers and the sunk costs related to state-of-the-art production equipment. It is possible that the rapid advances in Internet and communications technologies, for example, could have lowered the costs associated with seeking out suppliers and managing relationships with them.
Nevertheless, the relationship between technological change and outsourcing demand appears to be established. As a result, advises Bartel, “Be prepared to think more seriously about outsourcing as a way of dealing with technological change. If you are in a world in which technology is continually evolving, it may be expensive to try to keep pace. Outsourcing may be a solution.”
While the research is focused on manufacturing industries, its importance may extend further. As Bartel points out, “To the extent that technological change makes it costly to update technologies, [the research findings] would certainly be applicable to the outsourcing of services as well.”
