  1. The table reports the detailed results of the Tobit regressions discussed in "Regression analysis". Dummies for \(\alpha \in (0, 0.5, 1)\) not shown. Clustering and PageRank measures have been multiplied by 1,000. Robust standard errors in parentheses. Significance level: *** \(p<0.01\), ** \(p<0.05\), * \(p<0.1\).
