↵Notes: Results are from tests of pretrends. 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).
