This paper describes in detail the theoretical and empirical features of the G-Cubed multi-country, multi-sector intertemporal general equilibrium model. The G-Cubed model has been used for a number of alternative policy simulations including the implications of greenhouse gas policy, trade liberalization, tax policy and macroeconomic policy. The paper is intended as a technical guide to supplement policy-oriented papers. It does not include a survey of related literature; for that or other additional detail, including computer code for the model and analysis of a variety of policy simulations, refer to McKibbin and Wilcoxen (1994) or contact the authors.
[In reaction to Donald Trump Jr's tweet on air pollution and the relationship between pollution and socioeconomic status] It’s been well established that poorer folks and minority communities tend to live in areas that are more polluted. This isn't particularly new. [The tweet] contradicts what we know, and it's based in ignorance.
