Bar Ifrach; Director of Data Science, AirBnB

Search, Pricing, and Marketplace Dynamics at AirBnB

In his 2016 book Who Gets What -- and Why, Nobel laureate Alvin Roth defined three general principles for successful marketplace: thickness, congestion-free, and safe and simple. In this talk, we will illustrate these principles using unique examples from Airbnb's two-sided marketplace and tie them back to Airbnb's success. In addition, we will discuss challenges and solutions in measuring the efficacy of marketplace design changes in light of these principles.
