Organized markets and over-the-counter markets: some remarks based on the example of the Paris Stock Exchange in the 19th century.

Summary The last paper of the session was aimed at offering some insights from a later perspective. The researcher analysed and compared two market systems which coexisted in the 19th-century Paris Stock Exchange, the Coulisse (unregulated market) and the Parquet (strictly regulated), arguing for a complementarity of the two rather than a competition between them.
