Anecdotal evidence from the British Railway Mania and other historical financial bubbles suggests that many investors during such episodes are naive, thus contributing to the asset price boom. Using extensive investor records, we find that very few investors during the Railway Mania can be categorized as such. Although some interpretations of the Mania suggest that naive investors were expropriated by railway insiders, our evidence is inconsistent with this view as railway insiders contributed substantial amounts of capital, and their investments performed no better than those made by other experienced investors.

Firms engage in a multitude of interactions with the external environment, most critically with government and its regulatory agencies. Despite an extensive literature on “regulatory capture,” little attention has been paid to the interactions between merging firms and competition authorities. Yet the possibility of capture exists where there is a recurring series of merger investigations of one firm by the same authority. This analysis of the impact of political influence on the merger history of the brewing firm Scottish & Newcastle extends into a discussion of regulatory capture in the oversight of British brewery mergers during the 1980s and 1990s.

Unlike the majority of Spanish multinationals, which have developed only recently, firms in the publishing industry became international in the early twentieth century and have managed to hold on to much of their business, despite the instability of their own institutional systems and those of their principal host economies. Today, the Spanish publishing industry ranks fourth in the world, and its foreign markets continue to grow in North America, Europe, Latin America, and, most critically, in Mexico. The internationalization of Spanish publishing firms was fueled initially by a search for new markets and by linguistic and cultural advantages. With the passage of time, the process came to be built on accumulated knowledge and on the personal and social networks created by Spanish publishers, both inside and outside Spain.

This article examines the establishment of the field of operations research (OR) at the Arthur D. Little consulting firm and the Massachusetts Institute of Technology. OR advocates envisioned the field as a new kind of bureaucratic organ dedicated to general studies of business problems, staffed by trained scientists who could employ sophisticated methods if needed. The crux of their promotional strategy was to use their appreciation of general managerial practice to overcome the tensions to be expected from their claims to apply generic scientific methods to nonscientific activities. However, they discounted possible intellectual competition with established professions. This competition ultimately confined OR's identity to a jurisdiction defined by novel mathematical techniques.
