Innovation Diffusion and Physician Networks: Keyhole Surgery for Cancer in the English NHS

We examine the effect of a physician network on medical innovation using novel matched patient-physician-hospital panel data. The data include every relevant physician and all patients in the English NHS for 15 years and physicians’ workplace histories for more than 20. The dynamic network arising from physician mobility between hospitals over time allows us to separate unobserved physician and hospital heterogeneity from the effect of the network. We build on standard peer-effects models by adding cumulative peer behaviour and allow for particularly influential physicians (‘key players’), whose identities we estimate. We find positive effects of peer innovation take-up, number of peers, and proximity in the network to both pioneers of the innovation and key players. Counterfactual estimates suggest that early intervention targeting young, connected physicians with early take-up can significantly increase aggregate take-up.

Room: Due to the current situation regarding the COVID-19 pandemic, the talk will be held in a virtual seminar room. For more information click here.


New CINCH Working Paper

06.07.2021

A new working paper has been added to the CINCH working paper series: "The Health Externalities of Downsizing" by Alexander Ahammer, Dominik Grübl, and Rudolf Winter-Ebmer.

Abstract: We show that downsizing has substantial externalities on the health of workers who remain in the firm. To this end, we study mass layoff (ML) survivors in Austria, using workers who survive a ML themselves, but a few years in the future, as a control group. Based on high-quality administrative data, we find evidence that downsizing has persistent effects on mental and physical health, and that these effects can be explained by workers fearing for their own jobs. We also show that health externalities due to downsizing imply non-negligible cost for firms, and that wage cuts may have similar effects.

Evaluating Hospital Performance

There is an increasing interest in measuring and comparing the quality of care in hospitals. Widely used risk adjustment methods rely on observable characteristics to account for patient selection, but are often criticized for their inability to fully control for differences in patients across hospitals. We assess hospital performance using exogenous variation shaped by the institutional setting of inpatient care in Upper Austria. Hospitals have agreed on a rotating schedule, where on each day, one or two hospitals are primarily responsible for the admission of inpatients. For patients in need of acute care, this schedule creates a quasi-random allocation into different hospitals. We use this variation in an instrumental variable (IV) framework to estimate hospital performance, and compare the results to traditional risk adjustment methods. We use patient mortality and readmissions as quality indicators and draw on administrative data from Upper Austria with hospital visits from the years 2005 to 2018. We find substantial differences between IV and risk adjustment estimates, and show that increasing the number of variables used to control for patient differences often does not provide more credible results.
