Item Open Access Commitment-Flexibility Trade-Off and Withdrawal Penalties(Economic Research Initiatives at Duke (ERID), 2012-03-01) Ambrus, A; Egorov, GWithdrawal penalties are common features of time deposit contracts offered by commercial banks, as well as individual retirement accounts and employer-sponsored plans. Moreover, there is a significant amount of early withdrawals from these accounts, despite the associated penalties, and empirical evidence shows that liquidity shocks of depositors are a major driving force of this. Using the consumption-savings model proposed by Amador, Werning and Angeletos in their 2006 Econometrica paper (henceforth AWA), in which individuals face the trade-off between flexibility and commitment, we show that withdrawal penalties can be part of the optimal contract, despite involving money-burning from an ex ante perspective. For the case of two states (which we interpret as “normal times” and a “negative liquidity shock”), we provide a full characterization of the optimal contract, and show that within the parameter region where the first best is unattainable, the likelihood that withdrawal penalties are part of the optimal contract is decreasing in the probability of a negative liquidity shock, increasing in the severity of the shock, and it is nonmonotonic in the magnitude of present bias. We also show that contracts with the same qualitative feature (withdrawal penalties for high types) arise in continuous state spaces, too. Our conclusions differ from AWA because the analysis in the latter implicitly assumes that the optimal contract is interior (the amount withdrawn from the savings account is strictly positive in each period in every state). We show that for any utility function consistent with their framework there is an open set of parameter values for which the optimal contract is a corner solution, inducing money burning in some states.Item Open Access Delegation and Nonmonetary Incentives(Economic Research Initiatives at Duke (ERID), 2015-12-04) Ambrus, A; Egorov, GIn many contracting settings, actions costly to one party but with no direct benefits to the other (money-burning) may be part of the explicit or implicit contract. A leading example is bureaucratic procedures in an employer-employee relationship. We study a model of delegation with an informed agent, where the principal may impose money-burning on the agent as a function of the agent’s choice of action, and show that money-burning may be part of the optimal contract. This result holds even if action-contingent monetary transfers are possible, as long as transfers from the principal to the agent are bounded from below (as in limited liability or minimal wage requirements). In fact, the optimal contract can involve a combination of both efficient monetary incentives and inefficient nonmonetary incentives through money burning. Our model delivers some results novel to the delegation literature. First, money-burning is more likely if the principal is more sensitive to the choice of action than the agent. This is consistent with the perception that there is more bureaucratization in large organizations. Second, money-burning is more likely if the agent’s limited liability constraint is tighter relative to his participation constraint. This implies that a higher minimum wage distorts employment contracts towards using socially wasteful nonmonetary incentives, leading to a Pareto inferior outcome as the agent is still held down to his reservation value through increased money burning.Item Open Access Supplementary Appendix to 'Delegation and Nonmonetary Incentives'(Economic Research Initiatives at Duke (ERID), 2015-12-04) Ambrus, A; Egorov, GSupplementary Appendix to "Delegation and Nonmonetary Incentives."
