The Nexus between Energy Consumption Shocks and Economic Growth: Using BVAR Approach

This paper examines the nexus between economic growth and energy consumption shock, over the period 1990-2020, in Iran. We employ a Bayesian vector autoregressive (BVAR) with new prior functions, which will give results more acceptable consequences than the classical methods to study these relationships. This study estimates the relationship between energy consumption shocks and economic growth within a multivariate BVAR framework by including gross capital formation, Labor and carbon dioxide emission. The multivariate impulse responses to shocks in all the variables are obtained. The results show that, there is a positive impact of energy consumption shocks on economic growth in Iran and this means that energy consumption is crucial for economic growth. Also, the responses of economic growth to one-unit shock of gross capital formation and labor force are positive and the responses of economic growth to the one-unit shock of carbon dioxide emission is are negative

Economic activity and climate change

In this paper,we surve yrecent econometric contributions t omeasure the relationship between economic activity and climate change.Due to the critical relevance of these effectsfor the well-being of future generations,there is an explosion of publications devoted to measuring this relationship and its main channels.The relation between economic activity andclimate change is complex with the possibility of causality running in both directions. Starting from economic activity,the channels that relate economic activity and climate changeare energy consumption and the consequent pollution. Hence, we first describe the main econometric contributions about the interactions between economic activity and energy consumption, moving then to describing the contributions on the interactions between economicactivity and pollution. Finally, we look at the main results on the relationship between climate change and economic activity. An important consequence of climate change is the increasing occurrence of extreme weather phenomena. Therefore,we also survey contributions on the economice effects of catastrophic climate phenomena

Development and biodiversity conservation in Sub-Saharan Africa: A spatial analysis

A better understanding of the relationship between economic development and biodiversity loss is of great relevance, given the current rapid extinction of species along with challenges born from the context of economic development in poor countries. The purpose of the current study is to provide a sound analysis, within the framework of an Environmental Kuznets Curve, of the relationship between economic development and pressure on biodiversity. Drawing on the most up-to-date data on threatened species from 48 sub-Saharan African countries, we used Maximum-likelihood and generalized spatial two-stage least-squares estimators to account for spatial-autoregressiveness in the dependent variable, as well as in the explanatory variables and in the disturbances of the models. We find evidence that supports an inverted U-shaped relationship between development and biodiversity imperilment, measured as the percent of threatened bird species. The results also reveal some species-level differences in the biodiversity-development relationship, since the Environmental Kuznets Curve hypothesis doesn't hold for mammals. This analysis contributes to the literature by partially challenging the paradigm of a strictly negative relationship between biodiversity and development in a developing countries context
