A Dual-Phase Health Capital Model and Its Application to Health Co-benefit Modelling of Decarbonisation
… analysis of health into two distinct but related phases of childhood and adulthood. The two phases are specified with different assumptions reflecting the differing characteristics of childhood and adulthood. The most important distinction between the two phases is the manner in which investment …
