Dynamic Coupling of the Climate and Macroeconomic Systems

چکیده
RÉSUMÉ – Le couplage entre les systèmes naturels et anthropiques a motivé plusieurs travaux de modélisation macro-économique visant à représenter ces deux systèmes dans un cadre de modélisation intégrée, ces travaux sont l’objet de cette revue de littérature. Ces interactions, et en particulier les conséquences économiques des événements extrêmes, sont étudiées à l’aide d’un modèle de déséquilibre possédant une dynamique cyclique endogène. Ce modèle réagit plus fortement aux catastrophes climatiques durant les phase de récession que durant les phases d’expansion. Ces résultats jettent un doute sur les évaluations des conséquances du changement climatique qui se fondent uniquement sur des modèles de croissance moyennés de long terme. Dans l’optique d’une validation du modèle, nous décrivons une méthode originale utilisant l’analyse multicanal du spectre singulier permettant d’extraire les composantes cycliques des observations économiques.

Synchronization for Complex Dynamic Networks with State and Coupling Time-Delays
This paper is concerned with the problem of synchronization for complex dynamic networks with state and coupling time-delays. Therefore, larger class and more complicated complex dynamic networks can be considered for the synchronization problem. Based on the Lyapunov-Krasovskii functional, a delay-independent criterion is obtained and formulated in the form of linear matrix inequalities (LMIs)...

متن کاملDynamic Relationship Between Macroeconomic Instability and Private Investment in the Iranian Economy
This paper investigates the relationship between macroeconomic instability and private investment of the Iranian economy. The study uses a trivariate VAR(2)-GARCH(1,1)-in-Mean with diagonal BEKK approach to proxied inflation and exchange rate uncertainties as the main indicators of macroeconomic instability. Moreover, Bounds testing approach to level relationship applied to investigate the long...
متن کاملEffect of Sentiments on Macroeconomic Variables in Iran: A Dynamic Stochastic General Equilibrium Approach
This study aims to evaluate the effect of sentiments on Iran's economy through a New Keynesian Dynamic Stochastic General Equilibrium model in a closed economy. In this study, the coefficients of the proposed model are calibrated and estimated using the quarterly data of Iran's economy from 2004 to 2015. It shows that in the presence of sentiment, how stochastic impulses affect the main macroec...
متن کاملThe Effect of Change in Electricity Tariffs on Electricity Consumption and Macroeconomic Variables With Dynamic Stochastic General Equilibrium (DSGE) Approach
The purpose of this article is to investigate the impact of electricity tariffs in the domestic and industrial sectors on electricity consumption and macroeconomic variables. In this regard, statistical data for the period 1991-2020 based on seasonal frequency and dynamic stochastic general equilibrium approach (DSGE) have been used. In this study, it is assumed that there is a section in the h...
متن کاملDynamic Analysis of A Three-Rotor Flexible Coupling with Angular Misalignment
In this paper, the dynamic response of a three-rotor flexible coupling to the angularmisalignment has been studied. The coupling is a power transmission agent between the motor andgearbox, in the power transmission system of SAG Mill (semi autogenously mill) in the Gol-e-Gohariron ore complex in Sirjan, Iran. Degrees of freedom of the system are the model's lateral deflectionsand the rigid-body...
