Climate change adaptation and productive efficiency of subsistence farming: A bias‐corrected panel data stochastic frontier approach

We explore the impact of climate change adaptation on technical efficiency Ethiopian farmers using panel data collected from 6820 farm plots. employ Green's (2010) stochastic frontier approach and propensity score matching to address selection bias. Our results reveal that improves maize, wheat barley production. also show failure account for bias underestimates average level. findings imply expansion at larger scales will provide a double benefit by curbing climate-related risks increasing farmers. Moreover, credit access introducing mechanisms allow get enough water during main growing season enhance subsistence
