Experimental Design (Public)
|
Before
Alliance's network comprises 57 area sheds, 9 of which were excluded from the program for operational reasons. Out of the remaining 48 area sheds, 24 were randomly selected for the program, using equal strata size (N=4) across Alliance's six operational regions. Within each of the 24 selected area sheds (referred to as “areas” in the remainder of this text), either 2 or 6 distributors (out of an average of about 20 distributors per area) were randomly chosen for the advance payment program.
The design is thus nested with areas assigned to treatment and control, and distributors within treated areas assigned to treatment or control. All farmers associated with a treated distributor are eligible for treatment.

After
For the 2018-2019 season, Alliance is operating out of 62 area sheds. Alliance determines area boundaries or designations every season based on yields in the previous season or logistical drivers. A sample of 42 areas across the 6 regions were eligible for the program. 24 were randomly selected for the program, using equal strata size (N=4) across Alliance's six operational regions. Within each of the 24 selected area sheds (referred to as “areas” in the remainder of this text), either 2 or 6 distributors (out of an average of about 20 distributors per area) were randomly chosen for the advance payment program.
The design is thus nested with areas assigned to treatment and control, and distributors within treated areas assigned to treatment or control. All farmers associated with a treated distributor are eligible for treatment.
