Overview

Wharton Research Data Services is the data platform operated by the Wharton School of the University of Pennsylvania that academic, government and commercial institutions subscribe to for access to licensed research databases. Its vendor list spans more than fifty providers, including CRSP, S&P Global Market Intelligence (Compustat and Capital IQ), NYSE Trade and Quote (TAQ), OptionMetrics, Audit Analytics, BoardEx, LSEG, FactSet, PitchBook, Preqin, RavenPack, CSMAR and the Fama-French factors, with some datasets such as TRACE, OTC Markets and Federal Judicial Center data included for all subscribers. WRDS normalizes the data into a PostgreSQL-backed warehouse with documentation, linking tables and classroom guides.

Users reach the data through web query forms, the WRDS Cloud via SSH and JupyterHub, SAS Studio, FTP and direct PostgreSQL connections; the official wrds Python package (BSD-3-Clause) wraps the connection with helpers to list libraries and tables and run SQL, and R connects through standard PostgreSQL drivers. Accounts are issued by subscribing institutions by role (faculty, PhD, research assistant, master's and undergraduate, staff, class accounts) with expiration dates and mandatory two-factor authentication; each institution's subscription determines which databases are visible.

WRDS is the standard source for empirical finance and accounting papers because journals and referees expect CRSP/Compustat-based samples. Its constraints are institutional: individuals cannot subscribe, vendor licences prohibit redistribution and often restrict commercial use, downloads of very large tables (TAQ) must run on the WRDS Cloud, and availability of any specific database depends on the institution's contracts.

Editorial note on uncertainty. pricing_url omitted: subscriptions are negotiated per institution. Redistribution restrictions are stated per vendor licence rather than on a single public terms page.
