This paper, first, empirically investigates European emission allowance (EUA) prices and, second, evaluates emission trading as a policy measure. Applying combined jump GARCH models yields strong evidence of conditional jump behavior. This implies that EUA prices are subject to unexpected...

This paper deals with the economics of Bitcoins in two ways. First, it broadens the discussion on how to capture Bitcoins using economic terms. Center stage in this analysis take the discussion of some unique characteristics of this market as well as the comparison of Bitcoins and gold. Second,...

Als Folge des Ölpreisrekordhochs 2008 wurde sowohl in der allgemeinen Öffentlichkeit als auch in der akademischen Welt über die Ursachen dieses Anstiegs debattiert. Die Ausgabe der Reihe »Kurz zum Klima« fasst diese Diskussion zusammen und verweist auf einen Aspekt, der zwar an sich...

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 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...

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...
