Table 4. Estimated parameter values for different model versions using the data of experiments with 40 rounds and 60 rounds. The model versions are defined as follows: SP = probabilistic choice with social preferences, without learning and signaling; SP+L = probabilistic choice with social preferences with learning and without signaling; SP+L+S = probabilistic choice with social preferences with learning and with signaling; and L = probabilistic choice of income maximizers with learning and without signaling. See Table 2 for a list of parameters and their definitions. InL stands for maximum likelihood, AIC for Akaike Information Criterion, and BIC for Bayesian Information Criterion.   SP SP+L SP+L+S L φ 0.0069 0.485 0.440 0.260 ρ 0.639 0.909 0.607 - χ -0.987 0.898 0.587 - λ -(1) 0.888 0.887 0.875 δ -(1) 0.773 0.722 0.082 κ -(1) 0.021 0.027 0.005 θ -(0) -(0) 0.472 - η -(0) -(0) 0.473 - lnL -6062.6 -4754.6 -4730.4 -4970.8 AIC 12131.2 9521.2 9476.8 9949.6 BIC 12146.9 9552.6 9518.7 9970.6
