This paper proposes a new analytical framework with which to analyze the determinants of global CO2 emissions. It contributes to the existing literature by examining the determinants of CO2 emissions using a flexible functional form (transcendental logarithmic model), taking into account the...

This paper analyzes the impact of urbanization on CO2 emissions in developing countries, taking into account the presence of heterogeneity in the sample of countries and testing for the stability of the estimated elasticities over time. The sample covers the period from 1975 through 2003 for...

Sachzwänge im internationalen Klimaschutz: 1. Weltweit wirksame Begrenzung von Emissionen, 2. Nutzung der Ressource muss einen Preis haben, um Anreiz für sparsamen Umgang zu geben, 3. Pro-Kopf-Lösung (auch von Bundeskanzlerin Merkel gefordert), damit Indien und China mitmachen....

The 2008 episode of food price explosion, political turmoil, and human suffering revealed important flaws in the current global food architecture. This paper argues that to safeguard the strengths of the current system, four failures in market functioning and policymaking must be addressed....

R&D-based growth theory suggests that a larger population size raises either the long-run rate of economic growth (strong scale effect) or the level of per capita income (weak scale effect), with far-reaching policy implications. However, for modern times there is little empirical support for...

The IPAT-model developed by Ehrlich and Holdren is widespread in ecological economics in order to quantify the impact of population growth on environmental deterioration. We comment on this model and extensions proposed by several authors from a theoretical and empirical point of view.
