Notes: Change of IDES and change of household income per capita are calculated as the corresponding values in 2009 subtracting the corresponding values in 2007, respectively. A household with strong social ties to local leaders is defined as a household with at least one household member or one immediate relative (e.g., parents, children, and blood brothers) as local leaders; otherwise it is defined as one with weak social ties to local leaders. Since social tie evolves slowly, here we treated it as time-invariant. The number of observations is 101.
