Labor Market Distortions and Welfare-Decreasing International Emissions Trading
用多区域多部门可计算一般均衡模型分析国际排放交易在劳动力市场扭曲下的福利影响，发现排放许可出口国可能受损，但配合劳动力市场改革可使所有地区受益。
Using a multi-region, multi-sector computable general equilibrium model, this paper analyzes the effects of international emissions trading (IET) with a focus on labor market distortions. We construct four separate models with several different labor market specifications: (1) a model without labor market distortions; (2) a model with taxinteraction effects in the labor market; (3) a model with a minimum wage; and (4) a model in which a wage curve determines wages. We use these models to analyze how the effects of IET change according to model specification. The main results from the analysis are as follows. First, we found that IET generates gains for all participants in the model without labor market distortions. Second, even in the models with labor market distortions, importers of emissions permits are highly likely to benefit. Conversely, we show that the possibility of a welfare loss from IET is not as small for exporters of permits. In particular, in the minimum wage and wage curve models, we found that the exporters of emissions permits are likely to be disadvantaged. However, this also depends on the region in question. For example, China is likely to suffer under IET, whereas Russia is likely to benefit. Finally, if we implement policies to alleviate labor market distortion simultaneously with emissions regulation, all regions receive benefit from IET.
