A survey of the economic impact of climate change and the marginal damage costs shows that carbon dioxide emissions are a negative externality. The estimated Pigou tax and its growth rate are too low to justify the climate policy targets set by political leaders. A lower discount rate or greater...

88 estimates of the marginal costs of carbon dioxide emissions were gathered from 22 published studies and combined to form a probability density function. The uncertainty is strongly rightskewed. If all studies are combined, the mode is $5/tC, the mean $104/tC, and the 95 percentile $446/tC....

This paper investigates the role of emissions control on reducing the tail-effect of the fat-tailed distribution of the climate sensitivity. Through a simple analysis on temperature distributions and some numerical simulations using the well-known DICE model, we find that the option for...

The Ramsey rule for the consumption rate of discount assumes a transfer of money of a (representative) agent at one point in time to the same agent at another point in time. Climate policy (implicitly) transfers money not just over time but also between agents. I propose three alternative...

Ocean acidification is increasingly recognized as a major global problem. Yet economic assessments of its effects are currently almost absent. Unlike most other marine organisms, mollusks, which have significant commercial value worldwide, have relatively solid scientific evidence of biological...

Estimates of the impacts of observed climate change during the 20th century obtained by different integrated assessment models (IAMs) are separated into their main natural and anthropogenic components. The estimates of the costs that can be attributed to natural variability factors and to the...
