INCOME DIFFERENCES BETWEEN WORKERS OF THE
FORMAL AND INFORMAL SECTOR OF GUATEMALA’S
ECONOMY DURING 2018
Scientific research paper
Abstract
The present article pretends to determine significant income differences between
formal and informal workers, using three different econometric models: the Heckit
model, which corrects biased selections; the Mincer equation model, in which we
calculate the impact that one additional year of studies has on wage income; and
finally the Oaxaca-Blinder decomposition model, which estimates two salary linear
regressions in terms of observable characteristics by measuring differences and
salary gaps. The database used for these calculations draws on the 2018 National
Employment and Income Survey. The study concludes that there are important income
differences between formal and informal workers. The Oaxaca-Binder decomposition
model portrays a 99.89% wage gap. Of this gap, 32.63 % is attributed to allocation
differences, 72.05% to coefficient differences and the remaining 0.05% is attributed to
the interaction of coefficients and allocations.
