UCL School of Management is delighted to welcome Xavi Vidal-Berastain, Rochester, to host a seminar discussing ‘(Un)Expected consequences of becoming a new format shopper: A causal approach’

Abstract

We quantify the causal impact of new format/platform entry on a broad range of consumer shopping behaviors, including overall spending, frequency of visit, breadth and depth of basket and brand loyalty. This is a large undertaking, made feasible only by recent innovations in data availability and statistical methodology. In particular, we exploit machine learning and data fusion techniques to combine a rich collection of data on consumer choice and store entry decisions into a unified longitudinal panel and employ and extend frontier synthetic control methods to address issues of selection and heterogeneous response inherent to this context.
