The Workshop on Platform Analytics presents new scientific research on platform analytics. Past papers are archived below. Past talks are on YouTube.

2024 Call for Papers, Submission deadline: Oct. 15

The Workshop on Platform Analytics (WoPA) is a single-track, multi-disciplinary workshop presenting new research on platform analytics.

Platforms enable direct interactions between diverse groups of agents. Marketplaces connect buyers and sellers; media platforms connect advertisers, creators and viewers; sharing platforms connect resource owners with resource users; app stores connect developers and users. Platforms are pervasive in the digital economy. Sriram et al. (2014) cover some platform research topics in greater depth and point to foundational literature.

We construe Platform Analytics broadly as the use of data to improve decisions in platform contexts. Relevant decisions might include platform design, rankings, listings, usage, pricing, advertising, personalization, ratings or reviews. Relevant topics might include:
-network externalities;
-agent utility, search, matching, purchase or welfare;
-reputation, manipulation, trust or fraud;
-discrimination, diversity or fairness;
-competition within or between platforms;
-data privacy and sharing;
-antitrust or other regulations.
Ideal papers might show how to use platform data to improve decisions in platform contexts.

WoPA will be held in-person in San Diego on April 6-7, 2024. The organizers are Minkyung Kim (CMU), Davide Proserpio (USC) and Kenneth C. Wilbur (UCSD). The workshop is sponsored by the USC Marshall Initiative on Digital Competition.

We invite unpublished working papers on platform analytics for a competitive submission process. We welcome relevant submissions from government, industry or any academic discipline, including computer science, economics, information systems, marketing, operations or others.

This year we decided to use EasyChair for managing the conference and submission. Submit a paper by October 15, 2023, using the following link: SUBMIT A PAPER. Submission instructions can be found here.

Maximum one submission per submitting author. Please do not submit papers that are already published, accepted, or likely to be accepted before the workshop.

We will notify authors of accepted papers by January. Submitting authors and scientific committee members will be invited for early registration. The program will be posted at

We kindly ask for help distributing this announcement to interested researchers.

Travel, Accommodation, Directions

Travel to San Diego

Things that may not be obvious:

1. Domestic travelers to San Diego airport (code: SAN) may want to search Southwest Airlines as well as regular flight search engines. Southwest operates numerous flights.

2. The Tijuana International Airport (code: TIJ) is about a 40-minute drive from UCSD. A pedestrian bridge called the Cross-Border Express enables air travelers to disembark directly into the United States. Some international flights to TIJ are substantially cheaper than similar flights to SAN.

3. Those traveling within Southern California may consider the Pacific Surfliner. Consult for travel advisories or closures due to cliffside erosion. You could disembark in Solana Beach and take a ridesharing service to campus, or in Old Town and take the Trolley Blue Line to campus.

4. If you fly into SNA, LGB or LAX, be advised that public transit options to San Diego are limited. Consider renting a car.


There is no designated hotel for the workshop. We recommend the following options:

1. We recommend the Hilton La Jolla Torrey Pines, Residence Inn by Marriott, Sheraton La Jolla, or Hyatt Regency La Jolla At Aventine.

2. The Estancia La Jolla is a lovely boutique hotel within easy walking distance, but it is substantially more expensive. The Lodge at Torrey Pines and La Jolla Beach & Tennis Club are in a similar class but not quite as close.

3. San Diego has numerous other accommodation options. We recommend checking Hotels Combined or AirBnB. You may want to consider staying near a Blue Line Trolley stop if you do not rent a car. Or, you could stay in the Village of La Jolla, La Jolla Shores, or University City and rely on ride-sharing services or the MTS 30 bus.

Arriving at UCSD

1. The workshop will be held at the UCSD Rady School of Management at 5 Scholars Drive North. We recommend taxi or ride sharing as the easiest way to get to the Rady School, because they do not require parking or walking.

2. The UC San Diego Trolley Blue Line began operation in 2020 and connects UCSD to Downtown San Diego and the US/Mexico Border. Trolleys run every 15 minutes and fares can be paid on the PRONTO app. We recommend using the trolley with two caveats. The UCSD Pepper Canyon stop is a 20-minute walk from the Rady School, including a large hill. The trolley is usually busy and safe, but off-peak ridership can be unpredictable.
Relatedly, a cheap way to travel from SAN airport to UCSD is to take the airport's free Rental Car Shuttle, disembark at Admiral Boland Way, walk one block east on Palm Avenue across Pacific Highway, and board the Trolley Blue Line at the Middletown station, as described here.

3. Driving directions to the Rady School are here. UCSD Visitor Parking costs $4/hour, up to a maximum of $32/day. However, the number of visitor parking spaces is limited and may require search across multiple parking lots.

4. There are some free parking spaces in an unpaved lot at the Torrey Pines Gliderport, a 15-minute walk to the workshop site, or curbside on nearby Torrey Pines Scenic Dr. Hoewver, the lot may fill up early on weekday mornings.
