  1. Robust standard errors in brackets
  2. For participants in the field experiment, the dependent variables are dummy, taking value of one if individuals paid for the non-waiting consult. For participants in the CV exercise, the dependent variables are dummy taking value of one if individuals declared they would have paid for the non-waiting consult, given the hypothetical price and waiting time announced
