How trade splits up information sets and dealers carry out their brokerage of asymmetric information
In this paper we set forth a new perspective from which to understand and measure the brokerage of asymmetric information that intermediaries usually carry out. Firstly, we deal with partitions of a given set so as to lay grounds to our line of research. Secondly, we argue that trade splits up imperfect information sets, over which traders try to negotiate and profit, but also hide their opportunistic behavior from their counterparts.
