Read the paper: De Benedictis, L. (2005). Three decades of Italian comparative advantages, World Economy, pp.1679-1709 (material for lesson 6 in CD).
Find exports data for two countries and the world in 10 sectors of your choice (be careful at the unit of measure, which has to be homogeneous).
Calculate the Balassa index (idem, page 1685 eq.1-3) for each economy/sector (you will have 10 values for each economy)
DATA search suggestions for sectoral data:
UN Comtrade database: https://comtrade.un.org/data/
UNCTADStat: https://unctadstat.unctad.org/wds/ReportFolders/reportFolders.aspx?sCS_ChosenLang=en
Plot the Balassa index for Economy 1 (on the x-axis) and 2 (on the y-axis) to get a scatterplot graph. Highlight threshold x=1 (vertical line) and y=1 (horizontal line).
Briefly comment upon your graph on the basis of your results.
