The numbers reported for the pct_sold equation are average marginal effects based on a tobit regression, accounting for the probability of the dependent variable censored at 0 and 100
The numbers reported for the vbsc_rank1 and vbsc_top3 equations are average marginal effects based on a logistic regression. The numbers in parentheses are standard errors adjusted for VBSC clusters
