we show that an informationally consistent signalling equilibrium exists under
asymmetric information and the trading os shares that restores the time consistency of
investment policy, but leads in general to lower levels of investment than the optimum
achievable under full information and/or no trading. Contractual orovisions that change
the information asymmetry or the possisblity of profiting from it could eliminate both
the time inconsistency and the inefficiency in investment polices, but these contractual
provisions too are likely to involve dead-weight costs. Estavlishing which route or combination of routes serves in practice to maintain consistency remains for future research.
