Estimation of -choice (interacted specification).

Standard errors clustered by individual in parentheses. Restricted standard errors in square brackets (assuming independent sessions, no correlation between unconnected subjects in a session, no contemporaneous correlation between connected subjects, no correlation at lags between connected subjects). * p, ** p, and *** p (t-distribution with degrees of freedom, with the number of clusters. The restricted standard errors consider the same distribution as the individual clustering.).
