We consider a simple dynamic model of environmental taxation that exhibits time inconsistency. There are two categories of firms, Believers, who take the tax announcements made by the Regulator to face value, and Non-Believers, who perfectly anticipate the Regulator's decisions, albeit at a...

Dieser Beitrag macht auf drei umweltpolitische Herausforderungen aufmerksam, die im gegenwärtigen Diskurs zum Themenkomplex Klima- und Umweltschutz zumeist nur am Rande und lediglich ansatzweise behandelt werden. Abschnitt 2 erörtert, inwiefern "Fake News" ein Problem für Umweltpolitik...

Modellers have examined a wide array of ideal-world scenarios for regulation of greenhouse gases. In this ideal world, all countries limit emissions from all economic sectors; regulations are implemented by intelligent, well-informed forward-looking agents; all abatement options, such as new...

We set up a simple dynamic macroeconomic model with (i) polluting consump- tion and a preference for a clean environment, (ii) increasing returns in abate- ment giving rise to an EKC and (iii) sustained growth resulting from a linear final-output technology. The model captures two sorts of...

Vehicle taxation based on CO2 emissions is increasingly being adopted worldwide in order to shift consumer purchases to low-carbon cars, yet little is known about the effectiveness and overall economic impact of these schemes. We focus on feebate schemes, which impose a fee on high-carbon...

The topic of this note is issues related to R&D expenditures leading to improved technologies for reducing environmentally harmful emissions. The focus is on he following questions: Will a market economy where environmental policies are restricted to taxes or quotas give the socially efficient...

The Porter hypothesis suggests that environmental regulations, such as restricting firms to reduce pollution, stimulates innovations and create a win-win situation for the environment and for firms. It has received a great deal of attention from academics as well as bureaucrats who disagree...

Focusing on tail effects, I incorporate distributions for temperature change and its economic impact in an analysis of climate change policy. I estimate the fraction of consumption w*(τ) that society would be willing to sacrifice to ensure that any increase in temperature at a future point is...

"Any economic analysis of climate change policy requires some model that describes the impact of warming on future GDP and consumption. Most integrated assessment models (IAMs) relate temperature to the level of real GDP and consumption, but there are theoretical and empirical reasons to expect...
