Number of donation actions.

Table 5 contains coefficients of a Tobit model on the number donation actions taken per participant (left-censoring at 0), respectively. Columns 1, 2 and 3 were estimated using all observations (n = 233) and columns 4, 5 and 6 were estimated with the restricted sample (n = 201). Interaction terms of standing order and weekly/monthly reminders (results not included above) were never significant. Levels of significance ***p < 0.01 **p < 0.05 *p < 0.1.
