emld
function computes the MLD of education, with for any group of
countries included in the dataset developed in Jorda and Alonso (2017).
The function also provides a decomposition of this index in between-county
and within-country inequality.

countries |
character vector with the country codes of the countries
to be used. Some macro-regions are already defined and can be used
instead of the country codes: |
init.y |
the first year in which the function is calculated. Available years are 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010. |
final.y |
the last year in which the function is calculated Available years are 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010. |
database |
population subgrup for which the function is calculated. The following options are available:
|
plot |
if |
The estimates of the MLD for the specified group of countries can be easily derived by taking advantage of the decomposition of this family. It is computed as the sum of the following terms, which correspond to within- country and between, country inequality respectively (see, e.g., Cowell, 2011):
MLD_W=∑_{i=1}^{N} p_i MLD_i;
MLD_B=∑_{i=1}^{N} p_i log(μ / μ_i),
where N is the number of countries, MLD_i and p_i denote, respectively, the MDL and the population weight of the country i.
emld
returns a list with the following objects:
MLD
: evolution of the MLD of education
from the initial to the last year, decomposed in between-country
and within-country inequality.
countries
: countries used to compute the MLD.
If plot = TRUE
, graphical representation of the numerical results.
