"Exposing the Energy Behemoth: The Coal Syndicate and the Politics of Cartel Disclosure in Germany, 1890-1914"

This paper examines how cartelization in Germany’s coal sector at the turn of the century set off enduring debates on the compulsory disclosure of cartels’ internal information. In 1893, nearly a hundred coal mining companies in the Ruhr region united to form the Rhenish-Westphalian Coal Syndicate, a cartel organization that controlled over half of the country’s primary energy supply. The transformation of previously competing companies into a combined syndicate brought a level of market power previously unseen, sparking extensive regulatory, academic, and popular discussions on how to grapple with this emergent form of industrial organization. One thread of these debates was a proposed requirement for mandatory information disclosure. Politicians, journalists, academics, and other stakeholders argued that the Coal Syndicate and similar cartels should be subjected to stricter obligations to disclose their internal information—including meeting minutes, price lists, and contractual contents—which the proposers thought would serve as a foundation to tame the market power of cartels. This paper explores how contemporary actors discussed the potential and limitations of compulsory disclosure as a control mechanism against abusive practices by the Coal Syndicate. Simultaneously, it analyzes various strategies employed by the coal industrialists to conceal pertinent information—often referred to as “trade secrets (Geschäftsgeheimnisse)”—and to discredit disclosure obligations as a form of cartel governance. Tracing the tension between industry leaders and the broader public over corporate information allows for uncovering how transparency requirements emerged as an institutional repose to cartels as a nascent form of business organization in the pre-World War I era. More broadly, as the principle of “publicity” later became a cornerstone of cartel regulation in interwar Europe, this study identifies one of the intellectual origins of European cartel policy, rooted in grassroots, ongoing negotiations between coal producers and their critics on what to disclose and what not.
