About

David Holtz is an assistant professor in the Management of Organizations (MORS) and Entrepreneurship and Innovation groups at the Haas School of Business. He earned his PhD at the MIT Sloan School of Management, in the Information Technology (IT) group. He also holds an MA in Physics and Astronomy from Johns Hopkins University, and a BA in Physics from Princeton University.

Holtz studies the design of online marketplaces and platforms using large-scale online field experiments and novel digital trace data. His research agenda focuses on online trust and reputation system design, the business and societal impacts of personalized recommendations, and the design and analysis of field experiments in online marketplaces. His work has appeared in a number of journals and conferences, including The Proceedings of the National Academy of Science and the ACM Conference on Economics and Computation, and has been covered by popular news outlets, such as MSNBC, The Washington Post, and the Boston Globe. Before returning to academia, Holtz spent time in the Bay Area working as a data scientist and product manager at a number of technology firms, including Airbnb (where he was one of the founding members of the company's algorithmic pricing team) and TrialPay (acquired by Visa). In carrying out his research agenda, he continues to work closely with many leading firms in the tech sector, including Airbnb, Facebook, Spotify, Microsoft, and Etsy.

Coronavirus threat rises across U.S.: ‘We just have to assume the monster is everywhere’

The Washington Post  online

2020-08-01

A national strategy, whether advanced by the federal government or by the states working in tandem, will more effectively control viral spread than the current patchwork of state and local policies, according to a study from researchers at the Massachusetts Institute of Technology published Thursday in the Proceedings of the National Academy of Sciences.

The deadly cost of uncoordinated reopening of our states

The Hill  online

2020-05-27

Today, our team in the Social Analytics Lab at the MIT Initiative on the Digital Economy released a comprehensive study of the cost of uncoordinated responses to COVID-19. Our models combined daily, county-level data on shelter-in-place policies with movement data from over 27 million mobile devices, social network connections among 220 million Facebook users, daily temperature and precipitation data from 62,000 weather stations and county-level census data on population demographics to estimate the geographic and social network spillovers created by regional policies across the United States.

Study: There will be a "devastating cost of failure" if economic re-openings are not coordinated

TechRepublic  online

2020-05-27

There is a devastating cost associated with the current chaotic and uncoordinated reopening of states and cities across the US and the globe after the COVID-19 shutdown because "pandemics are interdependent phenomena," a new study shows. "Viruses and people's adherence to the government policies designed to contain them spill over from region to region," according to the study by the Social Analytics Lab at the MIT Initiative on the Digital Economy.

MIT Study shows 'devastating' cost of states reopening without coordination amid COVID-19

Yahoo! Money  online

2020-05-22

As more states continue to reopen, people are questioning how the government will prevent a new spike in COVID-19 cases. Sinan Aral, David Austin Professor of Management at MIT and Author of “The Hype Machine” joins Yahoo Finance’s On The Move to discuss why states need to coordinate reopening amongst each other.

MIT study: ‘Chaotic and uncoordinated’ reopening of states takes ‘devastating toll’

MSNBC  online

2020-05-21

A new MIT study shows the cost of the uncoordinated responses to coronavirus. When state and local leaders decide to open up against CDC guidelines, that can have an impact far beyond the borders of their homes.

Lack of coordination in reopenings could lead to more coronavirus spread, spillover between states

The Boston Globe  online

2020-05-21

New research released Thursday from MIT found that, during the lockdown, people networking through mobile phones, video conferencing, and social media appeared to influence the travel behaviors and adherence to government restrictions of those in other states, even places far away.

New MIT Study Shows The Cost Of The Patchwork Response To Coronavirus In The U.S.

WGBH  online

2020-05-21

A new study from MIT suggests that having uncoordinated reopening strategies may cause regional problems. According to the study, different state policies can affect how other people in adjacent states act during the pandemic. Social media can work in the same way and “alter the perception of the effectiveness of local policies.” If one saw a post on Facebook from someone in a state that no longer is calling for social distancing, there is a greater chance they will no longer view their own states social distancing guidelines as essential.
