The purpose of this paper was to assess the impact of warehouse receipt system (WRS) on output market of smallholder maize farmers in the Northern region of Ghana. Data was collected from 400 randomly selected maize farmers in six communities in the Northern Region. Apart from descriptive statistics, endogenous switching regression model (ESRM) and propensity score matching (PSM) were used for the analysis of data. Findings from both the ESRM and the PSM show that the main factors that positively affect smallholder farmers’ participation in WRS are access to loan, maize output, having established buyer, and membership of farmer-based organisation. Ownership of storage facility, and payment of taxes reduce the possibility of participation in WRS. Participation in WRS has the potential to increase the quantity of maize sold by 18% for additional price of GH¢34 per bag. In order to sustain the positive impact of WRS, farmers should be encouraged to join FBOs for consistent learning in order to increase their output.
