Production de footballeurs, réseaux marchands et mobilités professionnelles dans l'économie globale : le cas des joueurs africains en Europe
2008
This doctorate thesis in Human geography deals with the international trade and migration of African football players towards and within Europe through a relational theoretical framework. Through the case study of African footballers, the goal is to gain a better understanding of several ongoing mechanisms occurring in the context of the global economy, such as the new international division of labour, the emergence of global production networks and the segmentation of labour markets. The thesis pleads for taking into account the social embeddedness of the economic action and of social networks as fundamental analytical unity to understand the process of globalization.
Le commerce équitable et la société civile internationale : une chance pour la mondialisation d'un droit de l'économie solidaire
2003
SUMMARY The international trade law passes through a crisis of legitimacy following the inequitable character of its rules and the irrelevance of its principles to the peculiarities of the North-South relations. Being the legal translation of the capitalist free market economic system, these rules are to protect the mercantile and free trade values. In order to overcome this crisis the movement of fair trade has emerged and has since its origin been supported by members of the international civil society. Fair trade means taking into account the standard of living and the conditions of employment of the marginalized producers in developing countries so as to improve them. This study is an a…
The long memory of efficient market
2004
For the London Stock Exchange we demonstrate that the signs of orders obey a long-memory process. The autocorrelation function decays roughly as a power law with an exponent of 0.6, corresponding to a Hurst exponent H = 0.7. This implies that the signs of future orders are quite predictable from the signs of past orders; all else being equal, this would suggest a very strong market inefficiency. We demonstrate, however, that fluctuations in order signs are compensated for by anti-correlated fluctuations in transaction size and liquidity, which are also long-memory processes that act to make the returns whiter. We show that some institutions display long-range memory and others don't.
La sécurisation des parcours des apprentis à l'épreuve du temps et du choix politique
2013
En ligne sur : http://www.cereq.fr/index.php/content/download/7936/71610/file/Relief42.pdf; National audience; Autant de questions auxquelles cette communication apportera des éléments de réponse. Celle-ci se déclinera en trois étapes, présentée en trois sections. La première sera une connaissance du contexte, des contraintes de l'expérimentation, et de l'implication des acteurs. Le deuxième temps apportera un éclairage sur les jeunes apprentis et les impacts du tutorat après deux années d'observation. Enfin, l'objet de la troisième section sera de mettre en exergue les propositions quant aux pratiques transférables du dispositif et la décision finale prise par le conseil régional. Le carac…
The network of global corporate control.
2011
The structure of the control network of transnational corporations affects global market competition and financial stability. So far, only small national samples were studied and there was no appropriate methodology to assess control globally. We present the first investigation of the architecture of the international ownership network, along with the computation of the control held by each global player. We find that transnational corporations form a giant bow-tie structure and that a large portion of control flows to a small tightly-knit core of financial institutions. This core can be seen as an economic “super-entity” that raises new important issues both for researchers and policy make…
On the origin of power law tails in price fluctuations
2003
In a recent Nature paper, Gabaix et al. \cite{Gabaix03} presented a theory to explain the power law tail of price fluctuations. The main points of their theory are that volume fluctuations, which have a power law tail with exponent roughly -1.5, are modulated by the average market impact function, which describes the response of prices to transactions. They argue that the average market impact function follows a square root law, which gives power law tails for prices with exponent roughly -3. We demonstrate that the long-memory nature of order flow invalidates their statistical analysis of market impact, and present a more careful analysis that properly takes this into account. This makes i…
The intersection between family dynamics and e-commerce strategy in family businesses: Empirical investigation in China
2021
This book chapter aims to contribute to increase our understanding of how e-Commerce strategy is designed, implemented, and influenced by family dynamics in family businesses, in China. Our research followed an exploratory and qualitative approach to analyse e-Commerce adoption by three Chinese family businesses, two of which were located in Beijing and one in Xinjiang. We used semi-structured interviews with key informants in the firms, focused on business history, business resources, as well as its corporate and e-Commerce strategies, and the family influence on the adoption of such strategies. The interviews were prepared based on the findings of a preliminary review of the literature on…

Managing Risk in Financial Market in Shipping Industry
2011
Based on the knowledge from shipping we would like to study one option strategy for investments on shipping stocks. Since the term paper is relatively short we have chosen one market segment, namely the offshore market, and one shipping company, namely Farstad Shipping. We will use the theory of freight rates from Martin Stopford`s book, Maritime economics, and apply it to the real world. The reason for this is that the freight rates are the income for the shipping companies. Furthermore we will use the financial information from Farstad Shipping to see what the value of Farstad Shipping stocks should be in the future. This we will do based on the freight rates in the offshore market. The m…
Trading Nokia: The roles of the Helsinki vs the New York stock exchanges
2004
We use the Autoregressive Conditional Duration (ACD) framework of Engle and Russell (1998) to study the effect of trading volume on price duration (ie the time lapse between consecutive price changes) of a stock listed both in the domestic and the foreign market. As a case study we use the example of Nokia's share, which is actively traded both in the Helsinki Stock Exchange and the New York Stock Exchange (NYSE). We find asymmetry in the volume-price duration relationship between the two markets. In the NYSE the negative relationship is much stronger and exists both during and outside common trading hours. Outside common trading hours no such relationship is significant in Helsinki. Based …
