Note: Table based on the EU-measure; G20 involvement as country grouping criterion; general set of 53 elements. Within-group comparison (GR00, GR11, GR22) refers to pair-wise comparison between two IIAs belonging to the same group (GR0, GR1 or GR2), while between-group comparison (GR01, GR02, GR12) refers to the corresponding comparison between two IIAs belonging to two different groups. For example: GR02 is based on pair-wise comparison between IIAs which were signed by non-G20 countries on the one hand and IIAs which were signed by G20 countries on the other. Standard deviation in parentheses.
