The European Association for Banking and Financial History has just started a new working paper series, with Chris Colvin as one of the editors. Along with my co-authors, I have a new working paper available in this series. The paper looks at ownership diffusion in the last half of the nineteenth century. Surprisingly, we find that ownership was much more diffused in the past than we expected. It was also diffuse compared to twenty-first century corporations. The paper is available here .
