报告摘要：
marginal abatement cost (mac) is a critically important concept for efficient environmental policy and management. however, most empirical studies using frontier estimation methods tend to overestimate macs. there are three sources of upward bias due to the limited set of abatement options, inefficiency, and noisy data. to address the bias, a mac estimation approach based on convex quantile regression (cqr) is proposed by kuosmanen and zhou (2021, ejor), which has gained increased popularity in the empirical assessment of macs and the identification of least-cost pathways. this seminar will introduce the cqr approach, before reviewing its recent applications and methodological developments. future research avenues will also be discussed.
