The Workshop on Platform Analytics presents new scientific research on platform analytics.
Platforms enable direct interactions between agents. Marketplaces connect buyers and sellers; media platforms connect advertisers, creators and consumers; sharing platforms connect resource owners with resource users; app stores connect software developers and users. Network externalities distinguish platforms from traditional business models: Platform value to customers depends on how many other customers, of various types, are using the same platform.
Platforms have become pervasive in the digital economy. Most of the largest firms in the world are platforms, and there are also platforms of all sizes.
Platform design enables valuable connections, platform policies structure customer transactions, and platforms remediate when things go wrong.
Yet platform incentives may diverge from some customer interests, leading to some questionable practices.
Policymakers at all levels are grappling with platform issues, suggesting a need for deeper understanding of platform topics.
"The purpose of knowledge is action." We construe Platform Analytics broadly as using data to improve decisions in a platform context.
The decisions might be taken by platforms themselves, the customers they connect, policymakers or others.
The data might come from within a platform or outside it, and the improvement may be from any party's perspective.
WoPA's goal is to facilitate scholarly communication about platform analytics. We seek to promote high standards of evidence, relevance, openness, inclusivity and multidisciplinarity.
We thank the
USC Marshall Initiative on Digital Competition and
INFORMS Society for Marketing Science for sponsoring past workshops.

Overview
The Workshop on Platform Analytics presents new scientific research on platform analytics.
We invite new working papers on platform analytics for a competitive evaluation process. Most submissions will receive direct feedback from the program committee.
We welcome relevant submissions from government, industry or any academic discipline, including computer science, economics, information systems, marketing, operations or others.
The submission deadline is Dec. 4, 2024. The submission link is on Easychair: SUBMISSION LINK
We focus on new, unpublished work in the spirit of a workshop to help improve works in progress. Please do not submit papers that are already published, accepted, or invited for revision. Please do not submit working papers that were first written prior to January 2023. Maximum one submission per submitting author.
The workshop is scheduled for April 4-5, 2025, at the University of California, San Diego.

Travel to San Diego
1. Southwest Airlines operates the most flights to/from San Diego (airport code: SAN) but requires a separate fare search.
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. SNA is another alternate airport within driving distance.
3. Travelers within Southern California may consider the Pacific Surfliner. Consult PacificSurfliner.com for travel advisories or closures due to cliffside erosion. We recommend the Solana Beach stop with a rideshare to campus.
Accommodation
There is no designated hotel for the workshop. We recommend booking early.
1. For those who prefer rideshare services, we recommend the Hilton La Jolla Torrey Pines,
as it's reasonably priced and nearby (1.2 miles / 1.9 km).
2. For those who prefer public transit and walking, we recommend the
Residence Inn by Marriott or the
Sheraton La Jolla. They are about 30 minutes walk from the workshop venue, mostly across campus, and 10-15 minutes walk from the Nobel Drive trolley station.
3. The nearest and highest-quality choice is
Estancia La Jolla, a 10-minute walk. However, it is relatively expensive.
Similar alternatives include the
La Jolla Beach & Tennis Club
and the
Lodge at Torrey Pines.
Arriving at UCSD
1. The workshop will be held at the UCSD Rady School of Management at 5 Scholars Drive North. We recommend taxi, ride share or walking as campus parking is not always straightforward.
2. The UC San Diego Trolley Blue Line connects UCSD to Downtown San Diego near the airport. 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 hill. The trolley is usually busy and safe, but off-peak ridership can be unpredictable.
The trolley does not run to the airport directly, but the Middletown Trolley Station is only a short walk from the airport's free Rental Car Shuttle stop at Admiral Boland Way, as described here.
3. Driving directions to the Rady School are here. UCSD Visitor Parking costs $4.20/hour, up to $33.60/day. However, the number of visitor parking spaces is limited and may require search across multiple parking lots.
4. There is free parking in an unpaved lot at the Torrey Pines Gliderport, a 15-minute walk to the workshop site. However, the lot is popular and may be full.
