We study how people react to small probability events with large negative consequences using the outbreak of the COVID-19 epidemic as a natural experiment. Our analysis is based on a unique administrative data set with anonymized monthly expenditures at the individual level. We find that older...

Big data (BD) analytics is considered one of the most important general-purpose technologies of our era. Given the pervasiveness of BD across industries, both policy-makers and scholars have become particularly interested in assessing the effects of BD on firm performance. However, previous...

We look at the interplay between price promotions and peer influence in the case of movies in Video-on-Demand (VoD), which are non-storable information goods. We analyze the outcomes from a randomized experiment run for 3 consecutive months using the VoD system of a large telecommunications...

We propose a new strategy for proactive churn management that actively uses social network information to help retain consumers. We collaborate with a major telecommunications provider to design, deploy and analyze the outcomes of a randomized control trial at the household level to evaluate the...

In this paper we study the impact of time-shifting on TV consumption and ad viewership. We analyze the results of a field experiment in which a random sample of ”triple-play” households were given a set of premium TV channels broadcasting popular movies and TV shows without commercial...

Peer ratings have become increasingly important sources of product information, particularly in markets for information goods. However, in spite of the increasing prevalence of this information, there are relatively few academic studies that analyze the impact of peer ratings on consumers...

We study the effect of peer influence in the diffusion of the iPhone 3G across a number of communities sampled from a large dataset from a major European Mobile carrier in one country. We identify tight communities of users in which peer influence may play a role and use instrumental variables...

The deployment of Next Generation Networks (NGNs) is attractive from both technical and social perspectives, but market forces may not suffice to trigger the desired levels of investment. Cave (2004) and the European Commission (2010) describe how National Regulatory Authorities (NRAs) have...

The General Data Protection Regulation (GDRP) represents a dramatic shift in global privacy regulation. We focus on GDPR’s enhanced consumer consent requirements that aim to provide transparent and active elicitation of data allowances. We evaluate the effect of enhanced consent on consumer...
