As part of the DEFINE (Dynamic Ecosystem-FINance-Economy) team I have worked on the development of country specific DEFINE models, including the DEFINE-UK model and the DEFINE-ALBANIA model which is under development. This has involved combining the ecological stock-flow consistent (SFC) modelling approach of DEFINE, with country-specific empirical modelling approaches. These models therefore incorporate interactions between the macroeconomy, finance and ecological variables while also accurately reflecting the accounting structure of the country being modelled.
