In a model where firms face a continuous choice of how much to invest in environmental innovation, we show that an ever stricter environmental policy does not always lead to ever cleaner production methods and ever lower production of polluting goods. It does so when the abatement technology is...

The relationship between growth and pollution is studied through a vintage capital model, where new technology is more environmentally friendly. We find that once the optimal scrapping age of technologies is reached, an economy may achieve two possible cases of sustainable development, one in...

The literature on environmental R&D frequently studies innovation as a two-stage process, with a single R&D event leading from a conventional polluting technology to a perfectly clean backstop. We allow for uncertainty in innovation in that the new technology may turn out to generate a new...

We study the optimal R&D trajectory in a setting where new technologies are never perfect backstops in the sense that there is no perfectly clean technology that eventually solves the pollution problem once and for all. New technologies have stings attached, i.e. each emits a specific stock...

China, das Reich der Mitte, ist mit schwerwiegenden Umweltproblemen konfrontiert die hohe Kosten verursachen. Mit der zunehmenden Anwendung der Umwelttechnik kann der Herausforderung diese Problemfelder zu beheben sinnvoll begegnet werden. Die Indikatoren Wirtschaftswachstum, notwendiger Schutz...

This paper extends a standard Schumpeterian growth model to include an environmental dimension. Thereby, it explicitly links the pollution intensity of economic activity to technological progress. In a second step, it investigates the effect of pollution on economic growth under the assumption...

The introduction of the U.S. SO2 allowance-trading program to address the threat of acid rain as part of the Clean Air Act Amendments of 1990 is a landmark event in the history of environmental regulation. The program was a great success by almost all measures. This paper, which draws upon a...

Agriculture is one of the major greenhouse gas (GHG) emission sources in China. This paper aims to identify the key factors that have led to rising GHG emissions in China's agricultural sector in recent decades. This research allows for spatial dependence across provinces, making use of regional...

Christian Leßmann und Arne Steinkraus, Technische Universität Braunschweig, zeigen, dass die Technologie des CCS durch das gezielte Abscheiden von Kohlendioxid aus Kraftwerksabgasen und die anschließende unterirdische Speicherung desselben, trotz hoher Kosten, dazu beitragen kann, die...

Der Autoverkehr ist in vielen Städten zu einer hohen Belastung geworden: Lärm, überfüllte Innenstädte, Staus, Feinstaub- und Stickoxidemissionen sorgen für massive negative externe Effekte und haben eine heftige und kontroverse Diskussion um die Zukunft der Mobilität angeregt. Fahrverbote...
