This analysis builds on that of Baird et al. (2016), which analyzed the 10-year program impacts, in two important ways. First, it utilizes two more rounds of data (KLPS-3 and KLPS-4), which include improved measures of consumption, agricultural productivity, and household earnings. Second, the additional rounds of data allow for panel data analysis. The third round of the Kenya Life Panel Survey (KLPS-3) was conducted during 2011-2014, and the fourth round of the survey (KLPS-4) launched in mid-2017 and is currently ongoing.
