Path dependence, modularity and the offshoring of (some) physician services
PublicationThis paper integrates ideas from modularity and path dependency to explain the potential for and limitations of the offshoring of high value added physician services. While not all medical services are amenable to offshoring, a growing number of physician activities can be viewed as modular components which, at least technically, could be performed remotely. As a result, the presumption that concerns for efficiency dictate how...
