Visibility of contributions in Industrial Organization in international scientific journals.

This empirical study evaluates the relative importance of articles in industrial organization published in major general or specialized scientific journals, either english or french, using the new 1991 J.E.L. classification system. Contributions are examined within two recent periods, 1991-93 and 1994-96, and regrouped according to the nature of the article: theoretical (L100-L390); industrial policy (L400-L590); industry studies (L600-L990). A specialization progress indicator (IPS) may show the evolution of the editorial policy in relation with the treatment of the subject, while a rate of multiple reference (TRM) reveals the specific characteristics of the journals with respect to the type of article being published.Industrial organization; French journals; Sociology of economics; Journals ratings.

Market Power and Collusion on Interconnection Phone Market in Tunisia : What Lessons from International Experiences

We try in this paper to characterize the state of mobile phone market in Tunisia. Our study is based on a survey of foreign experience (Europe) in detecting collusive behavior and a comparison of the critical threshold of collusion between operators in developing countries like Tunisia. The market power is estimated based on the work of Parker Roller (1997) and the assumption of "Balanced Calling Pattern". We use then the model of Friedman (1971) to compare the critical threshold of collusion. We show that the "conduct parameter" measuring the intensity of competition is not null during the period 1993-2011. Results show also that collusion is easier on the Tunisian market that on the Algerian, Jordanian, or Moroccan one

Le tourisme dans les environnements littoraux et insulaires : permanences, limites et perspectives

International audienceCoastlines and islands are particularly affected by the development of tourism worldwide. Between "desired costal" and "fantasy Islands", these coveted spaces, with both their tangible and intangible dimensions, are opening to tourism. Attracted by the economic opportunities they so desperately need, and more or less aware of their comparative advantages and limitations, they deliver the most vulnerable preserved resources, the most vulnerable, which are the subject of complex relationships and issues.Les littoraux et les îles sont des espaces particulièrement prisés par le développement du tourisme à travers le monde. Entre « désir de rivages » et « île fantasmée », ces espaces convoités, tant pour leurs dimensions tangibles qu’intangibles, s’ouvrent au tourisme. Séduits par les opportunités économiques dont ils ont tant besoin, plus ou moins conscients de leur avantage comparatif et de leurs limites, ils livrent des ressources préservées, des plus vulnérables, autour desquelles se construisent de complexes relations et enjeux

Investigation of the unified rain attenuation prediction method with data from tropical climates

The semi-empirical method recently proposed by Silva Mello and Pontes (SMP) for the prediction of rain attenuation in slant paths is investigated in this letter. The SMP method uses the simplified model of equivalent rain cell and the concept of an effective rain rate. However, substantial deviations were observed in SMP predictions when compared to the rain cell diameters derived from experimental data. The measured rain rates and attenuations were obtained from three tropical climates (Australia, and USM and IIUM both in Malaysia). The measured rain attenuation complementary cumulative distributions (CCDs) were also compared to SMP and the Rec. ITU-R P. 618-11. The test results show that the ITU-R model performs much better compared to SMP method in the three tropical climates
