چکیده

This study uses a meta-analysis to synthesize the effects of agricultural cooperative membership on yield crops and livestock. It collects 158 estimated from 42 studies, covering 19 developing countries. Our analysis finds evidence that there exists positive publication bias in empirical literature, confirming researchers journals have preference publish articles report significant results. After correcting for bias, we find has small-sized insignificant effect yield. The meta-regression reveals variation reported can be largely explained by attributes such as sample type (full vs. subsample), ratio, econometric approaches (instrumental-variable based parametric approach, non-parametric approach or ordinary least square regression), size types (average treatment treated, average effects, coefficient), agro-product (grain others), climate zones (tropical non-tropical).
