    • The network shown here represents the structure of the product space as determined from the 1998-2000 periods. Holding the product space as fixed is a good first approximation, because the dynamics of the network is much slower than the one of countries. The Pearson correlation coefficient (PCC) between the proximity of all links present in this network and the ones obtained from the same network in 1990 and 1985 are 0.69 and 0.66, respectively (SOM text). This indicates that, although the network changes over time, after 15 years the strength of past links still predicts the strength of the current links to a considerable extent.

    • We repeated the same exercise with the rank of proximity instead of proximity itself in order to assess whether what matters is absolute or relative proximity. We found that absolute distance appears to be what matters most. Although transition probability increases linearly with proximity, they decay with rank as a power law. Moreover, the rank effect is stronger for products in sparser parts of the product space, where transitions are also less frequent. Thus, densely connected products can develop RCA through more paths than sparsely connected ones, indicating the importance of absolute proximity
