Ordinary least-squares estimates are shown in each pair of cells, with standard errors clustered at the region level reported below in parentheses. Each cell corresponds to a separate regression that includes region and year fixed effects and region-specific linear time trends, with independent variables in columns and dependent variables in rows. *, P < 0.10; **, P < 0.05; and ***, P < 0.01.
