Outcome variables	Household type and treatment effect	Decision stage		Effect on adoption	Chang e (%)
		To Adopt	Not to adopt
Log of yield variance:		(1)	(2)	(3)	(4)
1. DTMV vs all non-DTMV	Adopters (ATT)	12.89	12.77	0.13	1
	Non-adopters (ATU)	12.46	12.73	−0.27**	−2.1
	Heterogeneity effect	0.44	0.04	0.4	3.1
2. DTMV vs improved non-DTMV	ATT	12.89	12.76	0.14	1.1
	ATU	12.46	12.72	−0.26**	−2.0
	Heterogeneity effect	0.44	0.04	0.4	3.1
3. DTMV vs local	ATT	12.89	12.81	0.09	0.17
