TABLE 4.

Effects of Externalities on Probability of Domestic Criminalization of Human Trafficking, by Exposure Category (Hazard Ratios)

	Model 1 Destination countries	Model 2 Origin countries	Model 3 Transit countries	Model 4 Internal Trafficking countries
Vulnerability to the diversion of externalities (Neighbor’s policy weighted by Sum of Roads) (s)	1.02^*^#	1.03^#	1.03^*^#	1.01^#
US pressure	1.83	2.32^*	1.49	2.51^*
Rule of law (s)	1.67^*^#	1.21^#	1.31^#	1.50^#
Ratification of 2000 protocol	1.54^*	1.46	1.58^*	1.36

Note: Results are from a Cox-Proportional Hazards Model. Variable names followed by (s) are fit using smoothing splines. The reported values are either the hazard ratios, or the best linear approximation to the hazard ratios. All results based on two-tailed tests.

= linear effect significant at the .05 level.

= non-linear effect significant at the .05 level.
