  1. Notes: Total number of observations is 7,121. Specifications include a dummy for missing partner information. The contribution of each variable to the regional gap is given under the column “Decomp.” computed as the mean values of the decomposition using 100 random non-poor income sub-samples with the order of the variables in each replication randomised. Standard errors are given in parentheses and (*), (**) and (***) represent statistical significance at 10 %, 5 % and 1 % levels, respectively.
