Predictors of emission-adjusted efficiency in crop farms: interactions and non-linearities within the nexus of social, economic and natural factors.

The term 'emission-adjusted efficiency' (EAE) typically refers to technical efficiency, defined as the set of desirable and undesirable outputs relating to classical production factors such as land, labour and capital. However, standard approaches to estimating the drivers of EAE fail to capture the nonlinear nature of these relationships or their interactions with different qualitative factors. This study aims, firstly, to identify the determinants of EAE oriented towards minimising greenhouse gases emissions in the field crop system within the socio-economic-natural nexus, secondly, to discover the non-linear relations with EAE and the effects of qualitative variables and policies.
