This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and...

Climate change would impact different countries differently, and different countries have different levels of development. Equity-weighted estimates of the (marginal) impact of greenhouse gas emissions reflect these differences. Equity-weighted estimates of the marginal damage cost of carbon...

Because of risk aversion, any sensible investment valuation system should value less projects that contribute more to the aggregate risk, i.e., that have a larger income elasticity of net benefits. In theory, this is done by adjusting discount rates to consumption betas. But in reality, for...

The social cost of carbon (SCC), commonly referred to as the carbon price, is the monetized damage from emitting one unit of CO2 to the atmosphere. The SCC is typically obtained from large‐scale computational Integrated Assessment Models (IAMs) that consolidate interdisciplinary climate...

Recent literature on biofuels has questioned whether biofuels policies are likely to reduce the negative effects of climate change. In this paper we make two contributions to the literature. First, we study the market effects of a renewable fuel standard in a dynamic model taking into account...

Estimates of the marginal damage costs of carbon dioxide emissions require the aggregation of monetised impacts of climate change over people with different incomes and in different jurisdictions. Implicitly or explicitly, such estimates assume a social welfare function and hence a particular...

The issue of greenhouse gas (GHG) stabilization stands on three critical open questions. Namely, what are the impacts deriving from different levels of climate change and their distribution. What are the levels at which GHG concentration should be stabilized in order to avoid unacceptable...

This paper studies countries' incentives to develop advanced pollution abatement technology when technology may spillover across countries and pollution abatement is a global public good. We are motivated in part by the problem of global warming: a solution to this involves providing a global...

Over the past century, all OECD countries have been characterized by a dramatic increase in economic conditions, life expectancy and educational attainment. This paper provides a positive theory that explains how an economy might evolve when the longevity of its citizens both influences and is...

This paper examines the role of pro-social behavior as a mechanism for the establishment and maintenance of cooperation in resource use under variable social and environmental conditions. By coupling resource stock dynamics with social dynamics concerning compliance to a social norm prescribing...
