Table 4 Estimates of improved pigeonpea adoption rates (full sample) and their 95 % confidence intervals among all farmers
Parameters | Sample moments estimate | Classical probit joint exposure and adoption model | ATE probit adoption model |
|---|---|---|---|
Joint exposure and adoption rate (Probability of knowledge and adoption of at least one improved pigeonpea variety): | |||
In the full population | 0.14(0.10–0.16) | 0.14 (0.10–0.16) | 0.14 (0.10–0.16)*** |
Within the improved pigeonpea-exposed subpopulation | 0.38 (0.29–0.48) | 0.22 (0.19–0.26) | 0.39 (0.33–0.45)*** |
Pigeonpea adoption rate (Probability of adopting at least one improved pigeonpea): | |||
In the full population (ATE) | 0.41 (0.29 0.52)*** | ||
Within the improved pigeonpea –exposed subpopulation (ATE1) | 0.39 (0.33–0.45)*** | ||
Within the sub-population not exposed to the improved pigeonpea (ATE0) | 0.42 (0.26 0.57)*** | ||
Estimated population adoption gap: | |||
Expected non-exposure bias(NEB) | −0.27(−0.37–.17)*** | ||
Expected population selection bias (PSB) | −0.17 (−0.11–.07) |
