This paper investigates the role of extreme oil price increases in empirical studies of the macroeconomics of oil prices. The innovative approach of rolling impulse responses is applied and data on both the aggregate and the industry-level is considered. The results show that the first oil...

Als wirksamstes Mittel zur Beschränkung des weltweiten Ausstoßes von Treibhausgasen – insbesondere von CO2 – und somit zur Bekämpfung des Klimawandels wird gemeinhin die Einführung eines weltweit gültigen Emissionshandelssystems angesehen. Ein solches System beschränkt effektiv den...

This paper deals with three aspects of spectacular oil price episodes such as the one witnessed in 2008. First, the concept of temporary explosiveness is proposed as an empirical method for capturing this type of behavior. The application of a recently proposed recursive unit root test shows...

This paper contributes to the green paradox literature by using a resource extraction framework with heterogeneous energy sources. A key feature of the model is a capacity constrained green backstop resource, which implies the simultaneous use of the expensive backstop resource and the cheaper...

This paper is concerned with carbon price volatility and the underlying causes of large price movements in the European emissions trading market. Based on the application of a combined jump-GARCH model the behavior of EUA prices is characterized. The jump-GARCH model explains the unsteady carbon...

On 21 July 2005 China adopted an undisclosed basket exchange rate regime. We formally assess and envisage the gradual evolution of the renminbi over time. We utilise nonlinear dependencies in the renminbi exchange rate and describe the smooth transition of the renminbi/US dollar (RMB/USD)...

Die globale Erwärmung und die daraus resultierenden ökonomischen und sozialen Konsequenzen sind eng verbunden mit dem Ausstoß von Treibhausgasen. Dem Kyoto-Protokoll nach ist die Europäische Union verpflichtet, die Emissionen dieser Gase bis zum Zeitraum 2008/2012 um 8% gegenüber 1990 zu...
