In this experimental study, involving subjects from Abu-Dis (West Bank), Chengdu (China), Helsinki (Finland), and Jerusalem (Israel), we test for a presentation bias in a two-person cooperation game. In the positive frame of the game, a transfer creates a positive externality for the opposite...

We investigate the influence of two widespread compensation schemes, individual piece-rates and team incentives, on participants' inclination to lie, by adapting the experimental setup of Fischbacher and Heusi (2008). Lying turns out to be more pronounced under team incentives than under...
