Quelle est l'incidence de l'exportation sur la performance des entreprises? Le cas du secteur vinicole français.

2005

National audience; Confrontées à une baisse durable de la consommation de vins sur le marché national, de nombreuses entreprises du secteur vinicole français ont décidé d'accroître leurs exportations. Dans ce travail, nous analysons l'incidence de l'exportation sur la performance financière des entreprises. L'économétrie de données de panel nous permet de mettre en évidence une influence positive etsignificative de l'exportation sur la performance financière des 80 entreprises françaises de notre échantillon, au cours des années 90 (de 1991 à 1999).

Canonical correlation in multivariate time series analysis

1997

We analyze a class o f state space identification algorithms for time series, based on canonical correlation analysis in the ligth of recent results on stochastic systems theory calle d « subspace methods » .These can be describe as covariance estimation followed b y stochastic realization .The methods offer the major advantage o f converting the nonlinear parameter estimation phase in traditional V A R M A models identification in to the solution o f Riccati equation but introduce at the same time some no n trivial mathematical problem s related to positivity. The states o f the forward -backward innovations representation have an interpretation : Instrumental Variables estimators .

Informational interactions and the future of cities

1998

Present-day city growth is chiefly the result of new tertiary activities such as financial and producer services, R&D, or business administration. It seems that these activities need to be more spatially concentrated than traditional manufacturing activities. These new trends affect both the structure of cities and the structure of city systems. The specific nature of the new activities concentrated in city centers makes them information intensive. These activities consume human capital, knowledge and hightech capital, which are all rapidly changing inputs; they are based on complex decisionmakingprocesses; this renders them highly information-dependent. Inasmuch as these activities are the…

What is next for the Washington consensus? The fifteenth anniversary, 1989-2004.

2004

Winter2004/2005, Vol. 27 Issue 2, p, 7p; (AN 15818079); International audience; The article reports on the fifteenth anniversary of the Washington consensus with special focus on the past fifteen years accomplishments. Washington consensus was promulgated in 1989. In the past fifteen years, the United States saw some impressive growth with strong employment, low inflation, and high productivity gains, while emerging countries were hit by a string of financial crises. It states that the economic performance of developing countries in the past 15 years is disappointing at best, alarming at worst. It talks about the contributions of globalization in redefining the international currency stage.…

Gini index, inequality comparisons and maximim axiom : a paradox

1999

Inequality is appreciated only through a relevant measure, traditionally the Gini index, but this one presents a weakness that prevents to consider it as valid: to a same Gini may correspond many distributions. For the most simple case, a concentration curve with two linear segments, a criterion is proposed, based on the maximin: beside curves with same Gini, the more egalitarian is those in which each poor has the higher revenue. However, this does not allow to decide for two curves with different Gini: two indeterminate zones appear. This is extended to curves with three linear segments and two kinks.

A biproportional measure of multidimensional inequality

1999

Bradburd and Ross have proposed a measure of multidimensional inequality based on a quadratic-loss criterion: one matrix is compared to another even if they have not the same margins. This is reconsidered. One removes the effect of size variation between the analyzed distribution and the reference distribution by giving to the two matrices the same margins with a biproportional operator. The size differences inside the analyzed structure are removed by a bimarkovian biproportional operator. As homogeneity does not signify equality, the homogeneous reference structure is replaced by a uniform matrix to be compared to the first matrix.

The theory of informal transactions in bureaucracies: some qualifications

1986

The ambition of the paper is certainly not to change substantially Breton and Wintrobe‘s story. We can be sure that many of the differentpieces that they have forged and assembled in their book v ill be replaced or modified in the course of time. This is the fate of all interesting theories. But only time-consuming and collective efforts can achieve this. The only ambition of this paper is a small beginning in that direction. Section II of the paper compares some of the mechanisms, others than trust, vhich have been proposed to explain self-enforcing exchanges. Then, Breton 8nd Wint robe's modelling of trust and trust accumulation is looked at critically in Section III. Section IV presents …
