All models cluster SEs for studies. Logit0: dv is a dummy that is 1 if the participant has given nothing. OLS: dv is fraction of pie, normalized on the interval [0,1]. Tobit0: dv as in OLS, lower level 0. SEs in parenthesis

Logit0: dv is a dummy that is 1 if the participant has given nothing. OLS: dv is fraction of pie, normalized on the interval [0,1]. Tobit0: dv as in OLS, lower level 0. SEs in parenthesis.

Bubble size stands for frequency bubbles above the line: participant gives more to charity than to another prisoner.
