Abstract

This paper evaluates the impact of the Lungwena project using a local instrumental variable framework. It uses participation into a project component as treatment status while non-participation as control. The paper finds that participation into project interventions is positively influenced by household size, entitlement to land and education levels. Sanitation and livestock interventions contributed positively to household welfare.

Key words: Impact, asset index, endogenous interventions.
