One vs Many: Causal Analysis of Airbnb using a Quasi-Experiment

Project part of Summer Internship 2020 at IIM Ahmedabad. Duration: April 2020 - July 2020 Mentor: Prof. Anuj Kapoor, IIM Ahemdabad Details: Compared the service quality ratings of hosts who own multiple properties to those who own only a single property, using detailed property-level data from Airbnb from the cities of Amsterdam & Antwerp Employed a Difference-in-Differences Design to causally study the effect of government crackdown on hosts who own multiple properties and disentangle the effect on service quality rating of hosts Used Latent Dirichlet Allocation (LDA) to classify 15k guest reviews into Property based & Host based and hence established a shift from Property to Host based reviews after the crackdown Investigated heterogeneity in effects using data driven machine learning algorithm: Causal Forest Paper Revised and Re-submitted to Elsevier’s IJRM.
