Technology adoption and market allocation: The case of robotic surgery

ElsevierVolume 86, December 2022, 102672Journal of Health EconomicsAbstract

The adoption of health care technology is central to improving productivity in this sector. To provide new evidence on how technology affects health care markets, we focus on one area where adoption has been particularly rapid: surgery for prostate cancer. Within just eight years, robotic surgery grew to become the dominant intensive prostate cancer treatment method. Using a difference-in-differences design, we show that adopting a robot drives prostate cancer patients to the hospital. To test whether this result reflects market expansion or business stealing, we also consider market-level effects of adoption and find effects that are significant but smaller, suggesting that adoption expands the market while also reallocating some patients across hospitals. Marginal patients are relatively young and healthy, inconsistent with the concern that adoption broadens the criteria for intervention to patients who would gain little from it. We conclude by discussing implications for the social value of technology diffusion in health care markets.
