Note(s): Each observation consists in a vacancy. This table reports the OLS regression outputs using as dependent variables the TF-IDF intensity measure of the finer classification (group 2) described in section 4. The independent variable is the log of the employment HHI, measured at the industry (2-digit ATECO code), province (NUTS-3), and year level. All the regressions include year, province, industry, and occupation (ISCO 4-dig) fixed effects. Robust standard errors in parentheses ***p < 0.01, **p < 0.05, *p < 0.1
