Abstract

Research Summary: How will a platform firm's diversification affect its existing business? Using datasets on the rideshare and food delivery businesses in New York City, we find that the launch of Uber Eats reduced Uber's and Lyft's rideshare trip volumes, but these effects were weaker during rush hours. Additional theoretical and empirical analyses suggest that, while platform diversification enables complementors to share some resources across businesses, it may also create opportunities for complementors to oscillate other complementary resources, thereby diverting complementor resources in the existing business from both the diversifying and competing platform firms. Such sharing-enabled resource oscillation may be due to resource exclusivity at the transactional level and the lack of control by platform firms over resources at the organizational level. Managerial Summary: We investigate how Uber's and Lyft's rideshare business was impacted by Uber's diversification into the food delivery business with the launch of Uber Eats in Manhattan, New York City. We find that, compared to geographic zones where no restaurant joined Uber Eats, zones where a significant proportion of restaurants joined Uber Eats experienced a relative reduction in rideshare trip volumes for both Uber and Lyft. Our results suggest that platform firms should be aware of the hidden costs of diversification due to their lack of control over gig economy participants (e.g., rideshare drivers). In addition, managers should be mindful of the diversification moves made not only by their own firm but also by competing firms.
