UCL School of Management is delighted to welcome Prof. Jiwoong Shin, Yale, to host a research seminar discussing: The Impact of Gig Economy on the Product Quality through the Labor Market: Evidence from Ride-sharing and Restaurant Quality.

Abstract:

This paper seeks to demonstrate the impact of the gig economy on product quality in seemingly unrelated local industries through the labor market. Our empirical context is the quality of service for restaurants in the city of Austin and we examine how they were impacted by the exogenous exit and re-entry of rideshare platforms Uber and Lyft into the city due to regulatory changes. We leverage these exogenous shocks, and combine them with sentiment-analyzed data from Yelp reviews that capture how customers assess the quality of service at each restaurant. We show that, compared to control cities, customers in Austin become more negative about service quality when Uber and Lyft are present in the city. Additionally, we use rich data on employee turnover and wages to demonstrate that, compared to the control cities, service staff turnover indeed increases in Austin when Uber and Lyft are present. We also conduct several additional studies and robustness checks that are all congruent with our hypothesis that Uber and Lyft lower the quality of service in Austin restaurants by raising the turnover of their staff. Together, these results suggest significant ramifications of the gig economy on the broader industries through the labor market.
