We study platforms in the sharing economy and discuss the need for
incentivizing users to explore options that otherwise would not be chosen. For
instance, rental platforms such as Airbnb typically rely on customer reviews to
provide users with relevant information about different options. Yet, often a
large fraction of options does not have any reviews available. Such options are
frequently neglected as viable choices, and in turn are unlikely to be
evaluated, creating a vicious cycle. Platforms can engage users to deviate from
their preferred choice by offering monetary incentives for choosing a different
option instead. To efficiently learn the optimal incentives to offer, we
consider structural information in user preferences and introduce a novel
algorithm - Coordinated Online Learning (CoOL) - for learning with structural
information modeled as convex constraints. We provide formal guarantees on the
performance of our algorithm and test the viability of our approach in a user
study with data of apartments on Airbnb. Our findings suggest that our approach
is well-suited to learn appropriate incentives and increase exploration on the
investigated platform.
