Concerning the yard-sale model of asset exchange, some refinements of the results in the literature are given in both discrete- and continuoustime settings. The wealth concentration result is extended to possibly unfair games. In a fair case, an asymptotic behavior of every player’s wealth process is derived. In the continuous-time settings, the effect of a proportional capital tax is also investigated. It is not assumed that the frequency of transactions is homogeneous for every pair of players in the discrete-time settings, or that the intensity of transactions is homogeneous in the continuous-time settings.
