Climate skeptics argue that the possibility that global warming is exogenous implies that we should not take additional action towards reducing greenhouse gas emissions until we know more. However this paper shows that even climate skeptics have an incentive to reduce emissions: such a change of...

This paper analyzes two indexes in order to capture the volatility inherent in El Niños Southern Oscillations (ENSO), develops the relationship between the strength of ENSO and greenhouse gas emissions, which increase as the economy grows, with carbon dioxide being the major greenhouse gas, and...

Sechs Jahre nach der Verabschiedung des Kyoto-Protokolls im Dezember 1997 sind die meisten Länder der internationalen Staatengemeinschaft noch weit von den damals verabredeten Klimaschutzzielen entfernt. Im Jahre 2001 lagen die Treibhausgas-Emissionen in den OECD-Ländern, die im...

This paper investigates the economic implications of a comprehensive approach to sustainable greenhouse policies that strives to stabilise the atmospheric concentration of the five major greenhouse gases at an ecologically determined threshold level. In a theoretical optimisation model...

The behaviour of future policy-makers substantially influences future greenhouse gas emissions. Uncertainty about the motives of future policy-makers may thus strongly influence the climate policy strategies of current policy-makers. Analytical and numerical analyses in this paper confirm this...

When dealing with multiple greenhouse gases, we need some way to establish equivalence among gases. The Intergovernmental Panel on Climate Change (IPCC) has suggested the use of global warming potentials (GWPs) for making such trade-offs. We begin by examining the implications of such an...

One of the most important reasons by which Kyoto negotiations had suffered a setback at the COP 6 conference may be the unsatisfactory state about the previsions of Global Warming. This lack of knowledge may have such an influence on the formation of human opinion that we cannot to be amazed if...

We estimate the growth rate of the social cost of carbon. This is an indication of the optimal rate of acceleration of greenhouse gas emission reduction policy over time. We find that the social cost of carbon increases by 1.3% to 3.9% per year, with a central estimate of 2.2%. Previous studies...

Singapore is the most industrialized and urbanized country in Southeast Asia and is totally dependent on oil and natural gas imports to satisfy its energy needs. Its national energy policy framework seeks to find a balance between maintaining Singapore's competitiveness, improving energy...

Ausgehend von den institutionellen Grundlagen des JI-Konzeptes wird in diesem Aufsatz das Optimalverhalten der Jl-Parteien unter alternativen Regimebedingungen untersucht. Es wird zwischen staatlichen und privaten Investoren und zwischen dem gebundenen und dem ungebundenen Land (Vor-reiter)...
