“…Recent work indicates progress toward the development of more sophisticated long-term baseline scenarios such as the SSPs within CGE models (Ho et al, 2020). In terms of labor, while the proportion of models with an extended labor factor nest exceeded that of capital and land, only 7 dynamic CGE studies included a distinction other than skilled/unskilled (e.g., Karam, 2011) and no study dynamically incorporated change in demographic traits (e.g., age, gender, educational attainment) at the global scale. Labor disaggregation beyond the skilled/unskilled distinction is limited primarily by a lack of sufficient data to estimate the degree of substitutability between more granular demographic categories (e.g., male/female) and therefore most global models assume perfect substitutability (Boeters & Savard, 2011).…”
