URL des Documents de travail : https://centredeconomiesorbonne.cnrs.fr/publications/; Documents de travail du Centre d'Economie de la Sorbonne 2022.18 - ISSN : 1955-611X; We provide the first ever quantitative analysis of pricing and profitability of option trading in Paris from 1843 to 1939 based on a data source featuring more than 75,000 option prices. Using a special case of the Black (1976) option pricing model, we show that, albeit options were consistently undervalued, the market was still profitable for all the parties. We prove that the exceptional longevity of the Paris options market was based on a 4-pillars market microstructure: (1.) systematic underpricing of cheap options to attract gamblers, (2.) administration of settlement price by the brokers' syndicate, (3.) parimutuel-like betting operation and safety thanks to (4.) a sophisticated risk management in the position-taking style which minimized actual clearing price manipulation.

Firstly, the author shows that this strategy was born in the wake of the Viking and Laval cases, with the aim of using the standards and complaint mechanisms of the Council of Europe and the International Labour Organisation to overturn those case laws."

International audience; The sixteenth issue of Arabian Humanities concludes our special focus on Omani history and society. Our journal is proud to have gathered, over two issues, an impressive and diverse set of authors thanks to the fabulous commitment of three researchers: Marion Breteau, Sterenn Le Maguer and Maho Sebiane who have for long been partners of the Centre français de recherche de la Péninsule Arabique (CEFREPA). While the project had been launched before the Covid-19 pandemic and the end of the five-decade long reign of Sultan Qaboos, it is clear that many of the contributions have been impacted by these two historic events, if only through access to the field in Oman or by providing chronological milestones.In the Sultanate like elsewhere in the Arabian Peninsula, issues linked to travel have become an important matter for foreign researchers. The closure of airports due to the pandemic, the health procedures (however legitimate), and even certain specific costs have complicated our collective capacity to have access to the societies that we study. They have limited the possibility to carry out excavations for archaeologists, discover new archives or even interact, more or less formally, with colleagues who work in universities or academic institutions of the Arabian Peninsula and participate in scientific conferences.In that context, the CEFREPA’s very existence is more than ever an asset. As a French research center which has always valued its permanent presence in the Arabian Peninsula for more than four decades (first in Yemen, then in Saudi Arabia and finally in Kuwait, and has been able to establish partnerships to send researchers for long periods of time in the United Arab Emirates and in Oman), it remains a most relevant tool to reinforce local partnerships and establish fruitful observation posts. It is largely through mutual trust and patience, long standing relationships and collaborations with institutions and actors of the societies we work on, and most importantly we work with, that fieldwork makes full sense. The publications of this issue, focusing on Oman or other areas, are yet another testimony of a philosophy and methodology that despite various crises and difficulties, continues to structure our journal.
