Together with Michele Mancini and Alessandro Borin, we have just released a preliminary version of icio, a new Stata command for Global Value Chains (GVCs) analysis.

icio exploits the Inter-Country Input-Output tables: the WIOD dataset is the default, but also OECD TiVA and user-provided tables can be loaded.

By simplifying the analysis of trade in value-added and countries' participation in GVCs, the command should be useful for researchers that are not actively engaged in the GVCs literature.

You can install the command by typing in the Stata command bar:

ssc install icio

Once the command is installed, by typing

icio_load, iciot(wiod) year(2014)

a Mata version of the WIOD 2014 table is downloaded and stored in memory.

Several options are available (see help icio).

The command can compute:

  1. Value added in domestic and foreign demand, also at the sectoral level;
  2. Koopman, Wang and Wei (2014) decomposition of aggregate exports;
  3. Borin and Mancini (2017) decompositions of bilateral and bilateral-sectoral exports, retrieving for each bilateral flow, aside from the exporting and the importing country, also the country of origin of the value-added as well as the final destination market;
  4. Measure of GVC-related trade, defined as goods and services crossing at least two borders (again following Borin and Mancini, 2017).

Of special note is that it is possible to define country-groups and to use user-provided IO tables. In the next release of the command, a dialog interface will be added.
