Top panel: the WTW bow-tie structure, composed by the SCC and the IN-component only. The panels below show the countries belonging to the SCC (in colors) and the countries belonging to the IN-component (in gray) in 1993, 1998 and 2002, respectively. Countries belonging to the SCC keep rising their reciprocated degree (see also Figure 2); richest world countries (Canada, Europe, Japan, in dark red) are always characterized by the largest values of reciprocated degree.
