The bargaining set of a large economy with differential information

We study the Mas-Colell bargaining set of an exchange economy with differen tial information and a continuum of traders. We established the equivalence of the private bargaining set and the set of Radner competitive equilibriu m allocations. As for the weak fine bargaining set, we show that it contain s the set of competitive equilibrium allocations of an associated symmetric information economy in which each trader has the "joint information" of al l the traders in the original economy, but unlike the weak fine core and th e set of fine value allocations, it may also contain allocations which are not competitive in the associated economy.
