Over the last few decades, integrated assessment models (IAM) have provided insight into the relationship between climate change, economy, and climate policies. The limitations of these models in capturing uncertainty in climate parameters, heterogeneity in damages and policies, have given rise...

In the absence of significant greenhouse gas (GHG) mitigation, many analysts project that atmospheric concentrations of species identified for control in the Kyoto protocol could exceed 1000 ppm (carbon-dioxide-equivalent) by 2100 from the current levels of about 435 ppm. This could lead to...

The latest round of international negotiations in Copenhagen led to a set of commitments on emission reductions which are unlikely to stabilise global warming below or around 2°C. As a consequence, in the absence of additional ambitious policy measures, adaptation will be needed to address...

This paper focuses on a single firm with constant returns to scale in a multi-period setting with incomplete markets and a single good per state. Profits vanish whenever the firm maximizes profits with respect to a given price system. The paper addresses the following question: Shall the firm...

This paper analyses issue linkage as a way to increase co-operation on issues where incentives to free-ride are strong. The goal is to determine under what conditions players prefer to link negotiations on two different issues rather than to negotiate on the two issues separately. Suppose that...

This paper looks at the interplay between human capital and innovation in the presence of climate and educational policies. Using recent empirical estimates, human capital and general purpose R&D are introduced in an integrated assessment model that has been extensively applied to study climate...

In the paper we consider the role of seasonal intercepts in seasonal cointegration analysis. For the nonseasonal unit root, such intercepts can generate a stochastic trend with a drift common to all observations. For the seasonal unit roots, however, we show that unrestricted seasonal intercepts...
