The estimates in this table are from a linear regression of the number of citations for a given paper on the interaction between an indicator for having received a negative citation, and indicators for the years before and after the negative citation event. In the first column, the sample includes the full sample of cited papers-years. In the second column, the sample is restricted to the papers that received a negative citations and a matched sample defined as described in Algorithm to Determine the Matching Sample for the Analyses Reported in Fig. 6. SEs, clustered at the cited paper level, are in parentheses. ***P < 0.01, **P < 0.05, *P < 0.1.
