While recognising these important differences between the two papers, it none the less seems reasonable to see how well their separate results for enforcement fit. Christensen et al (2013) list in Table 1 of their paper the countries for which they find significant enforcement changes between 2001 and 2005, while Brown et al (2014) list in Table 5 of their paper country enforcement indices for 2002 and 2005, from which the changes over this period (not allocated to specific years) can be calculated.
