Note: Table based on the EU-measure; G20 involvement as country grouping criterion; subset-if. 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. Standard deviation in parentheses. Eight of the originally used 53 elements that are rather related to some key aspects of WTO's investment facilitation initiative such as transparency, predictability and efficiency are considered in the subset-if.
