Table 3. Summary of system response to shocks. Rm and Cm refer to the minimum resource and consumption levels reached during the shock, respectively. Wl refers to the cumulative welfare loss suffered during the shock in each region (per capita shown in parenthesis), and WT shows the cumulative welfare loss for all three regions, i.e., the quantity defined by Equation 14. NM = no migration, WM = with migration, WM&C = with migration and cultural (social) factors.
