Notes: All estimates are difference-in-differences estimates for
coefficient κt for period t=1 (after the intervention).
Standard errors are shown in parentheses. Statistical significance is
denoted as follows: *** p<0.01; ** p<0.05; *
p<0.1. The specification controls for time and farm fixed
effects. The subsamples are as follows: JV1 is furthest north in the
Jordan Valley, and represents a set of farms that were mostly unaffected
by the Compact since their water supply is independent of the Zarqa
system; JV2 and JV3 represent areas where flows of recycled wastewater
newly arrived (JV2) and increased substantially (JV3); JV4 represents an
area that already had substantial flows of recycled water prior to the
investment; Highlands farms, finally, are located along the Zarqa River
and also received access to more steady water supply.
