Abstract
This IE evaluates the impact of subsidized delivery of agricultural inputs on food security and agricultural revenue, particularly focusing on targeting of youth. Within the sample, farmers of varying ages are offered the subsidized seeds and tools and also sent an SMS based e-voucher enabling them to buy rice or fertilizer. The IE studies the impact of these inputs on household outcomes and tests whether youth or more experienced farmers are the best targets for similar programs.

Experimental Design
Experimental Design
Distribution of tools and seeds included in the technical package of inputs from the SAPEC project will be randomly phased in at both a community level and at a farmer level within communities. All farmers who registered in the national government's e-registry of farmers who cultivate rice, cassava, or vegetables are eligible, but the order of communities and farmers within communities will be randomly phased in.
Experimental Design Details
Not available
Randomization Method
Stratified randomization written in STATA by the World Bank research team.
Randomization Unit
Electoral areas (an official unit close to a community level) are randomly assigned to treatment in the year of intervention overlapping the IE. Within the electoral areas, eligible farmers were randomly assigned to be enrolled or not in the SAPEC subsidy scheme.
Was the treatment clustered?
Yes
Experiment Characteristics
Sample size: planned number of clusters
97 electoral areas
Sample size: planned number of observations
1,100 farmers
Sample size (or number of clusters) by treatment arms
500 farmers receive the subsidy in 50 treatment communities. An additional 100 farmers did not receive the subsidy in these 50 treatment communities. 500 farmers in 47 control communities did not receive the treatment.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
