This paper develops a forward-looking, dynamic general equilibrium model with imperfect competition to study the welfare (sectoral and aggregate) effects of Canada's compliance to the Kyoto Protocol. In particular, it introduces a Chamberlinian competition framework in the analysis in order to capture firms' departure from marginal-cost pricing. It analyzes both the long-term and the transitional effects of the Protocol in Canada by using a national carbon emission permit scheme for fossil fuel use as the cost-effective policy instrument required to achieve the desired level of carbon emissions. It assesses the underestimation of the welfare and GDP losses, if any, associated with the assumption of perfect competition in all markets.

Addressing the poverty and distributional impacts of carbon pricing reforms is critical for the success of ambitious actions in the fight against climate change. This paper uses a simple framework to systematically review the channels through which carbon pricing can potentially affect poverty and inequality. It finds that the channels differ in important ways along several dimensions. The paper also identifies several key gaps in the current literature and discusses some considerations on how policy designs could take into account the attributes of the channels in mitigating the impacts of carbon pricing reforms on households.

China faces many modernization challenges, but perhaps none is more pressing than that posed by climate change. China must find a new economic growth model that is simultaneously environmentally sustainable, can free it from its dependency on fossil fuels, and lift living standards for the majority of its population. But what does such a model look like? And how can China best make the transition from its present macro-economic structure to a low-carbon future? This ground-breaking economic study, led by the Stockholm Environment Institute and the Chinese Economists 50 Forum, brings together leading international thinkers in economics, climate change, and development, to tackle some of the most challenging issues relating to China's low-carbon development. This study maps out a deep carbon reduction scenario and analyzes economic policies that shift carbon use, and shows how China can take strong and decisive action to make deep reductions in carbon emission over the next forty years while maintaining high economic growth and minimizing adverse effects of a low-carbon transition. Moreover, these reductions can be achieved within the finite global carbon budget for greenhouse gas emissions, as determined by the hard constraints of climate science. The authors make the compelling case that a transition to a low-carbon economy is an essential part of China's development and modernization. Such a transformation would also present opportunities for China to improve its energy security and move its economy higher up the international value chain. They argue that even in these difficult economic times, climate change action may present more opportunities than costs. Such a transformation, for China and the rest of the world, will not be easy. But it is possible, necessary and worthwhile to pursue.

An economic evaluation of the impact of policies intended to control emissions of CO2 and other ''greenhouse gases'' (GHGS) depends on the net costs of these controls and their distribution throughout the production sectors of developed and developing economics. The answers derived from appraisals of these net costs, in turn, stem from what is assumed about the timing of the controls, the pace of technological change, and any short-term secondary benefits from their control. There have only been a few serious attempts to estimate the economic benefits from the policies associated with such long run outcomes. All of the approaches to date have made fairly strong assumptions or relied on contingent valuation estimates of hypothetical situations.
