dec_: Performs decomposition of the quantile difference (of y)...

In gibonet/decr: Tools to Perform Decompositions of Differences Between Two Groups

Performs decomposition of the quantile difference (of y) between two groups (in 2 components) in the common support.

Description

Performs decomposition of the quantile difference (of y) between two groups (in 2 components) in the common support.

Usage

dec_(.dec_, counterfactual = c("AB", "BA"))

Arguments

.dec_	output of dec_median or dec_quantile.
counterfactual	"AB" or "BA". "AB" means that we want to estimate the counterfactual (wage) of group A, as if their characteristics were distributed as in group B. "BA" is the opposite (characteristics of group B are balanced to those of group A).

Value

a list with four components:

• probs: the chosen quantile level;

• delta_tot: total observed difference between the quantiles (of wages) of group A and B (all the sample);

• delta_tot_CS: total observed difference between the quantiles (of wages) of group A and B in the common support;

• delta_AB: difference explained by the fact that the two groups have some combinations of characteristics that the other group has not.

• delta_X: part explained by the fact that the two groups have a different distribution of characteristics (same combinations of characteristics) but distributed differently);

• delta_S: part not justified by the different distributions of the characteristics of the two groups, and potentially due to a difference in the remuneration structures between the two groups.

Examples

data(invented_wages)

# Common support and computation of counterfactual weights
r00 <- reweight_strata_all2(invented_wages, treatment = "gender",
                       variables = c("sector", "education"),
                       y = "wage", weights = "sample_weights")

# Computation of the elements necessary to the decomposition
d00 <- dec_quantile(r00)

# Decomposition of the difference of the medians of the two groups
# (in the common support) in two components
dec_(d00)
