In the absence of this assumption, the coefficient includes any spillovers on the non- MWS in high versus low FracMWS provinces. The results for β Infant are presented in Table 4. We estimate a significant coefficient of −0.0065 ( p < 0.01). This suggests that a 10 percent increase (~1sd) in the fraction enrolled in MWS prior to 30 Baht leads to a reduction in infant mortality of 0.65 per 1,000 births.
