The flexibility to renegotiate can facilitate long-term contracting and thereby beneficial reliance investments and risk allocation. The prospect of modification can induce contracting parties who expect their bargaining power to improve to enter into contracts earlier and realize the advantages of longer-term relationships. Otherwise, those parties might decline to contract or delay until those opportunities realize, thereby foregoing the benefits of long-term risk allocation or reliance investments. The parties decide not only whether, but also when, to make legally binding commitments to each other. Courts should be more lenient in enforcing contract modifications that, prompted by a shift in bargaining power, may have only a redistributive effect. Parties can design under-compensatory damages that would provide a credible threat of breach ex post to facilitate ex post modification. Requiring good faith in modification (along with damages) can constrain possible holdup and protect reliance investments and risk allocation.
