decompr

Demonstration

Description

Two Global Value Chains decompositions are implemented. Firstly, the Wang, Wei, and Zhu (2013) algorithm splits bilateral gross exports into 16 value added components. Secondly, the Leontief decomposition (default) derives the value added origin of exports by country and industry, see Leontief (1937).

Additional tools for GVC analysis are available in the gvc package.

Installation

You can install the latest stable version from CRAN.

install.packages('decompr')

The development version, to be used at your peril, can be installed from GitHub using the devtools package.

if (!require('remotes')) install.packages('remotes')
remotes::install_github('bquast/decompr')

Usage

Following installation, the package can be loaded using:

library(decompr)

For general information on using the package, please refer to the help files.

Credit

The Wang-Wei-Zhu algorithm (wwz())is based on R code written by Fei Wang (not to be confused with the author of the algorithm, with the same last name), which implemented this algorithm.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
