Average Profit (ECU) cumulated during each Session (B1, B2, N1 and N2). We sum the profit of each player and take the average in each round to calculate the average individual profit. We measure profit in Experimental Currency Units (ECUs, 1 ECU = 3 DKK). The number of rounds varies between sessions (86 rounds in B1, 51 in B2, 73 in N1, and 57 in N2). The dashed black line shows the expected profit if all subjects follow our suggestion
