Note: The base period is 1999–2000, which we refer to as wet period 1. Blank cell entries correspond to marginal effect estimates that are not statistically distinguishable from zero at the 10% significance level. The values in parentheses represent the marginal effects translated into 2009 dollars using the average value for each respective sample. For parcels not subject to export restrictions, the percentage effects shown here are translated from the baseline, uninteracted coefficients in Table 2. For parcels subject to export restrictions, the effects are translated from the combined baseline and interaction coefficients. To conserve space, we do not translate the relative effects for restricted parcels (i.e., the interaction coefficients on their own). The marginal effects for groundwater volatility, orchard/vineyard share, and idled cropland share are not statistically distinguishable from zero.
