This article presents a new model to manage the provision of healthy food despite incomplete information about exposure of natural resources to a persistent pollutant (chlordecone). This toxic molecule has contaminated both terrestrial and aquatic resources for several decades in the French West Indies. As a consequence, the threat of exposing huma...
This article deals with the implementation of the agroecological transition in the French West Indies. To address this challenge, a viability model is suggested. This approach offers an original framework to highlight agroecosystems dynamics by allowing consideration of simultaneously economic and agronomic dimensions. This holistic approach to agr...
1 Abstract
Uncertainty occupies a major place in the literature, both when it is being defined and when it is being measured. The mathematical viability theory framework provides useful concepts to go beyond the probabilistic views of uncertainty that are not able to capture all forms of uncertainty, particularly in the absence of statistical regul...
The Earth is an evolutionary system that can be viewed as a Social-Ecological System built around Money (SESM) because of the coupling of the Anthropocene Era with globalization. Given the simultaneous (environmental-economic) risks of “total uncertainty” and “systemic aftermath”, several paradigmatic turns are required. Ecological economics is a c...
La vulnérabilité des petites économies insulaires (PEI) a fait l’objet d’analyses approfondies depuis les années 1970. Le poids du secteur agricole est notamment décrit comme un facteur intrinsèque de leur vulnérabilité. Afin de tester cette assertion, nous avons élaboré un indicateur composite de vulnérabilité agricole (AVI) basé sur le poids de l...
This article suggests a generic method to compute a composite index of vulnerability and resilience from a sustainable development perspective: the Net Vulnerability-Resilience Index. A worldwide application shows that both vulnerability and resilience are policy responsive. From the worst to the ideal, the state of vulnerability-resilience can be...
Vulnerability–resilience indexes fail to grasp all dimensions of sustainability, whereas sustainable development has gained momentum. We fill this gap with a hierarchical multimetric composite index (Net Vulnerability Resilience Index: NVRI) whose robustness relies on a mathematical algorithm based on graph theory. A worldwide application shows tha...
Since the 70s, scholars have assumed that the structural features of the agricultural sector are intrinsic factors of vulnerability for Small Island Territories. This article aims at testing the relationships between the weight of agriculture and the macroeconomic vulnerability. We build a composite index to measure agricultural vulnerability: AVI....
Several assessments of vulnerability and resilience have been attempted at a country level through composite indices but they are barely in accord with a holistic view of sustainable development. We suggest graph theory to structure a network of variables that depict vulnerability and resilience from a sustainable development perspective. Vulnerabi...
Using the structural unobserved component (UC) modeling, this study will analyzes
the Senegalese economic growth path after 5 decades of independence by focusing on the
potential output, the GDP cycle, and the type of shocks on the GDP. Empirical evidence
suggests that an inventory cycle mainly drives the GDP short-term component with a
time-varyin...

Identify specific aspects of mixed farming systems. At the same time, certain practices seem to transcend the whole territory and relate little to the activities that dominate a zone. To be able to organize a follow-up of these promising complex systems at farmer and experimental level situation a first evolutionary assessment grid was sketched to...
This study focuses on the US monetary policy rule during the subprime crisis. Two stances could be taken: a totally ineffective monetary policy or an insufficiently effective one. To arbitrate between those two positions, the effectiveness of each monetary transmission channel around the crisis period is estimated across the time. Our results point...
Monetary policy contributes to stabilize growth. Particularly in a reforming context for financial and economic activities, it is important to know how central bankers’ decisions through the short term interest rate of the money market are transmitted to the real variables: the GDP and the inflation. Few studies on monetary transmission mechanisms...
Many have questioned the empirical relevance of the Calvo-Yun model. This paper adds a term structure to three widely studied macroeconomic models (Calvo-Yun, hybrid and Svensson). We back out from observations on the yield curve the underlying macroeconomic model that most closely matches the level, slope and curvature of the yield curve. With eac...
Assessing tourism macroeconomic net profitability Costs-benefits analysis of international tourism returns
Studies of the economic impact of tourism returns rarely offer a comparison between their potential driving effects and the costs of their accumulation. The aim of this paper is to devise a tourism macroeconomic profitability indicator capable...
The paper is an empirical study on contagion during the 1997-1998 Asian crisis. In line with Sander and Kleimeier [Sander, H., Kleimeier, S., 2003. Contagion and causality: an empirical investigation of four Asian crisis episodes. International Financial Markets, Institution and Money 13, 171-186], Granger causality among Asian economies on soverei...
The lack of theoretical consensus on the causality direction between real and financial spheres as well as on the macroeconomic importance of transmission channels drive to an empirical approach of the links between the two areas. The aim of this paper is to offer a method for the analysis of the causal structure between the two spheres according t...
Résumé -De nombreuses études discutent de l'hypothèse d'un effet richesse sur la consommation des ménages. Les études micro-économiques et macroé-conomiques aboutissent à des résultats contradictoires. Le prix d'actif peut être interprété comme un indicateur d'enrichissement des ménages ou un indicateur avancé de croissance future. La relation caus...
Small islands developing states constitute a fruitful topic to work on concerning the question of vulnerability and resilience. As debated in the economic literature, these territories present structural characteristics - smallness, remoteness and insularity - that are considered as strong handicaps, which impede their development. Several empirica...

The chlorinated polycyclic ketone pesticide chlordecone (CLD)
resulted in a persistent pollution of soils with health hazard through the food chain supply. In Guadeloupe and Martinique, the issue is now to regulate animal productions systems despite economic and environmental uncertainties motivated by human actions. The Mathematical Viability Theory is here helpful to provide solutions that combine short term and long term objectives that are hardly compatible and that associate economic and health targets.
This research project focuses on the adaptation of agricultural systems in small island territories face of global change with land application as privileged small French Antilles. The choice of these small island territories is that they crystallize the panorama of issues related to global changes underway, and they are representative of the diversity of tropical environments.
