Table 4 Estimates of improved pigeonpea adoption rates (full sample) and their 95 % confidence intervals among all farmers

From: Determinants of agricultural technology adoption under partial population awareness: the case of pigeonpea in Malawi

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)
