Key Findings -There is very little micro-level empirical literature estimating farm to non-farm labor linkages from agricultural productivity growth in Africa. Our study helps to fill this gap in Zambia. -We find that a doubling of district level crop productivity is positively associated with a 14%- 17% increase in non-farm labor activity among rural farm households in Zambia. -This impact is even more pronounced for changes in small farm district productivity (<2 hectares), causing a 24%-31% increase non-farm labor activity among rural small farm households. -There is also some evidence, although it is less robust, that increases in productivity among relatively lower productivity farms (relative to each district), also increases non-farm labor activity. -Overall, these results align with the structural transformation hypothesis with regards to labor linkages, and can be used to help justify support for improvements in small-farm crop productivity.
