The Intergovernmental Panel on Climate Change predicts that climate change will induce considerable environmental degradation globally during this century. What are the implications of this prediction for the patterns of population migration and political conflict? Climate change is an evolving environmental phenomenon whose effects are not yet fully manifested. This paper strives to gain insig...

We study the impact of timing and commitment on adaptation and mitigation policies in the context of international environmental problems. Adaptation policies present the characteristics of a private good and may require a prior investment, while mitigation policies produce a public good. By developing a stylized model, where some countries coordinate their actions while others do not, we evalu...

Cross-country data on energy consumption, GDP and vulnerability are used to measure percentage changes in vulnerability associated with percentage changes in per capita GDP and per capita energy consumption. Energy consumption, through its nonlinear effects on per capita income, have the effect of reducing a country’s overall vulnerability to climate change by a greater amount at moderate incom...

In the wake of the global change of a new accumulation regime in major capitalist economies, the opening up and liberalisation process of emerging economies from the 1980s has provoked great expectations that resulted in recurrent disappointing crises. Studied as a stylized fact, the Turkish experience leads us to assess the role of liberalised macroeconomic environment, unsuitable economic pol...

Midcentury targets have been proposed as a guide to climate change policy that can link long-term goals to shorter-term actions. However no explicit mitigation analyses have been carried out of the relationship between midcentury conditions and longer-term outcomes. Here we use an integrated assessment modeling framework with a detailed representation of the energy sector to examine the depende...

I study the general equilibrium implications of large-scale policies to improve energy efficiency, which are being implemented around the world to mitigate climate change. Energy efficiency policies “rebound” when economic responses undercut their direct energy savings. I develop an analytic general equilibrium framework that allows improvements in energy efficiency to affect output prices and ...

Since the middle of the twentieth century, the problem of making inferences about the point in a surveyed series of observations at which the underlying distribution changes has been extensively addressed in the economics, biostatistics and statistics literature. CUSUM type statistics have commonly been thought to play a central role in non-sequential change point detections. Alternatively, we ...

â â â  given companies’ dynamic responses to expected exchange rate changes, this article improves on current methods of measuring exposure to foreign exchange rate changes by breaking down the spot exchange rate changes into expected changes and unexpected changes. the currency risk exposure coefficients resulting from an empirical analysis of shanghai stock exchange a share listed companies...

pierre-gerlier forest and his colleagues make a strong argument for the need to expand policy capacity among healthcare actors. in this commentary, i develop an additional argument in support of forest et al view. forest et al rightly point to the need to have embedded policy experts to successfully translate healthcare reform policy into healthcare change. translation of externally generated i...
