This paper is based on the work of Aghion and Howitt. We have integrated some elements including the tax on the dirty production, varieties production function and the isoelastic utility function. Furthermore, we analyze how the growth theory integrates the environmental dimension. We find that,...

There is a large literature on the optimal order of exploitation of natural resources. We explore the impact of specific technical progress that enables the saving of resource inputs in production on the order of exploitation. Models of growth tend to assume uniform and global technical progess....

Ce document présente une analyse théorique du comportement de R&D et d’innovation technologique d’une firme minière en situation de monopole. Deux types d’innovations de processus d’extraction y sont proposés. D’une part la R&D débouchera sur des innovations réductrices de coût,...

L'engouement pour les energies substituables, non conventionnelles, sera-t-il economiquement viable et donc durable? Certains des interets qui se rejoignaient pour encourager l'exploitation de la biomasse a des dfins energetiques se sont progressivement emousses. Le renouveau de l'interet en...

L’artisan est né en France (juridiquement) pendant la crise de 1929. L’objectif principal de ce texte est de faire le point sur l’histoire de l’artisanat depuis le moyen âge à nos jours. L’artisan pouvait ainsi être un serf au moyen âge, et est un entrepreneur aux 20-21ème...

This paper extends the Solow-Swan growth model by incorporating environmental factors, applied specifically to Madagascar. The model simulates three scenarios: (1) a baseline scenario with low savings and high deforestation; (2) an economic reform scenario with increased savings but no...

This article analyzes the territorial resilience of the Mananjary district in Madagascar in response to tropical cyclones, focusing on the communes of Tsaravary and Tsarahafatra. The study employs a multivariate Probit model to examine three hypotheses: the relevance of resilience policies, the...

This study develops a hybrid model to integrate climate risks into Côte d'Ivoire’s economic policy, drawing on the work of economists like Keynes, Ostrom, Stiglitz, Sen, and Nordhaus. The model combines decentralized governance, climate risk externalities, and capacity building to address the...

In this paper, I study the strategic interactions between a country that owns a monopoly on a polluting non renewable resource (basically, the OPEC), and a representative of countries that both consume the resource and are hurt by its pollution. Both pollution control and rent captation are at...
