Really a Nontraded Commodity? – Datasets and code now available

Figure 1: Trade network for fresh potatoes.The most successful contribution to this blog is (a little to my own surprise) our analysis of the international potato trade network Really a Nontraded Commodity?

For all those who are interested in what’s behind that work, or who want to take the analysis further, or simply want to know how these graphs have been produced we have now made the matrices of bilateral trade in fresh, frozen, and seed potatoes as well as the R code publicly available.

(Thanks, zenodo, for this great service!)

    nice post. Shows the utility of social network analysis very nicely. What about domestic trade? How much of potato production is consumed on farm versus taken to market?

    Thanks for the kind words, Glenn.

    The answer to your question (as you might expect) would certainly be: “It depends”. For the developing world, it’s maybe best to see the potato as a dual crop, parts of which are consumed on farm and parts sold to the market, with a tendency towards the latter. An analysis from Eastern Africa*, for example, shows that farmers in Kenya sell 81% of their potatoes, in Uganda 70%, and in Ethiopia 61%.
