Village-level characteristics are calculated using 1999 Census data from the Kyrgyz National Statistics Committee. The number of observations (villages) in each Column of Panel A match the number of villages selected in each of the years, except 2004 in which there was one village that could not be matched to the census data. Household-level characteristics are calculated using the Kyrgyz Integrated Household Survey for 2003. Columns 1–4 shows variable means by selection year, with standard deviations in brackets. Columns 5–7 show differences between selection years and the standard errors are in parentheses with statistical significance denoted by: ***p < 0.01, **p < 0.05, *p < 0.1. Household calculations have standard errors clustered at the village level. Plot size variable drops outliers (top 5% of observations).

Column 1 presents results using just 2003 data. Column 2 presents results using just 2004 data. Column 3 shows results of Column 2 minus Column 1. The sample for these calculations is limited to those villages that eventually receive infrastructure through the program. “Late villages” are those selected after 2004, whereas the “early villages” are those selected in 2003 and 2004. Details on the village selection are described in the paper text. Standard errors are clustered at the village level and in parentheses. Statistical significance is denoted by: ***p < 0.01, **p < 0.05, *p < 0.1. Plot size variable drops outliers (top 5 percent of observations).

Baseline means are calculated for 2003–2004. Amounts harvested are in log kilograms. All Columns include controls for (1) land characteristics (total plot size, number of land plots total, and proportion of land that is privately owned); (2) number of people and children 14 years and younger in a household; (3) district-year fixed effects; and (4) village fixed effects.

Their definition of acute intestinal infections includes dysentery, giardia, enterobaeces, acariasis, and acute viral hepatitis. Sample is limited to those villages that were eligible to receive the water infrastructure through the program. All regressions include village fixed effects.

Total farm work is the total number of minutes that all working-age household members spent working on the farm in one 24-hour period. All specifications include village fixed effects, district-year fixed effects, and day-of-week fixed effects. The log cereal values are calculated using Kyrgyzstan-specific FAO Annual Producer Prices for each crop in the analysis.
