Description Usage Format References Examples

Description

Data on support for the 2016 referendum for peace with the FARC in Colombia, as discussed in Hazlett and Parente (2020). The main "treatment" variables are santos2014, which indicates the share of town population voting in support of Santos in the 2014 Presidential election, and fat_2011to2015_gtd, which indicates the number of fatalities due to FARC violence between 2011 and 2015, again at the town level. The main outcome of interest is yes_vote, the proportion (0-100) at the town-level voting in support of the peace referendum. The question of interest in Hazlett and Parente (2020) is what can be said about the causal effect of either violence (fatalities) or of political affiliation with Santos, recognizing that analyses of either cannot likely rule out all confounding.

### Model 1 (bivariate)
model1 <- lm(yes_vote ~ fat_2001to2005_gtd, data = colombia)

### Model 2 (more controls, and lagged violence.)
model2 <- lm(yes_vote ~ fat_2001to2005_gtd + fat_2006to2010_gtd +
               fat_2011to2015_gtd + total_eligible + santos10 + gdppc ,
             data = colombia)

### Sensitivity analysis - Model 2, for effect of most recent violence.
sense.model2 <- sensemakr(model2,
                          treatment = "fat_2011to2015_gtd",
                          benchmark = "santos10",
                          kd = 1)

### contour plot point estimate
plot(sense.model2)

### contour plot t-value
plot(sense.model2, sensitivity.of = "t-value")

#---------------------------------------------
# Political Affiliation Model
#---------------------------------------------

### Model 3: santos2014 as measure of political support for Santos, with control variables.
model3  <- lm(yes_vote ~ santos14 + fat_2010to2013 + elev + gdppc + pop13,
              data = colombia)

### Sensitivity analysis - Model 3
sense.model3 <- sensemakr(model3, treatment = "santos14",
                          benchmark = c("gdppc","elev"),
                          kd = 3)
summary(sense.model3)

### contour plot point estimate
plot(sense.model3, lim = .9)

### contour plot t-value
plot(sense.model3, sensitivity.of = "t-value", lim = 0.9)
