Fig. 2: Estimating trade in digital products.
From: Estimating digital product trade through corporate revenue data
a We estimate bilateral trade in digital products (in USD) for 2,502 firms (belonging to 187 parent companies) and 13,013 important app developers starting from data on their revenue in each digital sector (icons from Envato Elements). We then use a gradient-boosted regression tree to estimate missing digital product consumption links and use optimal transport to assign consumption to firm revenues. b Firm level exports when all revenues are assigned to the headquarters location of the company. c Firm level exports when the revenues are assigned to the fiscal residence of subsidiaries.
