The Ignored Performance Measure

This paper studies a setting in which a risk-averse agent must be motivated to work on two tasks: evaluating a potential project and, if the project is adopted, implementing it. Although a performance measure that is informative of an agent's action is typically valuable because it can be used to improve the risk sharing of the contract, this is not necessarily the case in this two-task setting. I provide a sufficient condition under which a performance measure that is informative of the agent's implementation effort is worthless for contracting despite the agent being risk averse. This shows that information content is a necessary but not a sufficient condition for a performance measure to be valuable.     

Optimal Contracts for Long-Term Decisions and the Threat of Dismissal

This paper studies a simple agency model where an agent's decision can affect his or her own future payoffs as well as the principal's. The threat of dismissal becomes an important part of an incentive scheme even if the principal can use the performance-based wage contract. However, if the agent's future payoffs depend on the past realized performance, but not on the past decision directly, or if the agent is risk-neutral, it is not optimal to use the threat of dismissal. As the agent's discretion over his future payoffs increases, the principal relies more on the threat of dismissal but less on the wage contract.     

Multiproject team assignments

We consider expected profit maximizing mechanisms for a principal who has to allocate a group of agents among a number of projects, assuming that the principal has incomplete information about each agent's ability type, and the agents follow the Bayes-Nash or the dominant strategy equilibrium behavior. We find that while expected profit maximizing mechanisms are similar to the optimal auction (Myerson, 1981), the incentive compatibility constraints are much more restrictive. Interestingly, these constraints are satisfied if each agent's characteristics change in a consistent manner not only with types, but also from project to project.

Task assignment,incentives and technological factors

In this paper, we examine the allocation of tasks between a principal and an agent considering their incentives to provide effort, their different abilities in handling tasks, and transmission costs. We focus our attention on two tasks: the first may be handled by the principal or by the agent, whereas the second is necessarily carried out by the agent. Under a fully decentralised organisation, the agent performs both tasks, whereas, under partial delegation, the principal handles the first task and transfers the outcome to the agent who handles the second task. Assuming technological complementarities, from our analysis it emerges that, if there is imperfect observability of effort, full delegation is better at eliciting effort by the agent in the second task, whereas, in comparison with partial delegation, it lowers effort in the first task. Although with contractible effort, the choice between the two organisational forms depends only on transmission costs and on the relative ability of its members, when moral hazard problems are taken into account, the organisational choice is related to the relative importance played by the two tasks in production. If the agent's task is relatively important in production, full delegation, encouraging a higher level of effort in this task, may be optimal, even if technological factors favour partial delegation.

项目投资评价的两种盈亏平衡点比较分析

净现值准则是最重要的项目投资财务评价方法,当其他准则与其得出冲突的结果时,应以净现值准则为准。然而,在对项目进行盈亏平衡分析时仅仅计算会计利润盈亏平衡点,因而它与评估项目的准则不一致。鉴于此,笔者认为有必要计算现值盈亏平衡点。本文通过两种不同盈亏平衡点的计算和比较,进一步得出现值盈亏平衡点更具有优越性的结论。     

Limited Liability and Bonus Contracts

This paper studies the nature of incentive contracts between a risk-neutral principal and a risk-neutral agent under the constraint that the agent's liability is limited. A necessary and sufficient condition is derived for the existence of a first-best contract under this constraint, and a bonus-based contract is shown to be the most efficient contractual form. Implications of bonus contracts are also discussed.     

US‐style contingent fees and UK‐style conditional fees: agency problems and the supply of legal services

Under contingent fees, the attorney gets a share of the judgment; under conditional fees, the lawyer gets an upscale premium if the case is won which is, however, unrelated to the adjudicated amount. We compare conditional and contingent fees in a principal–agent framework where the lawyer chooses unobservable effort after she has observed the amount at stake. Contingent fees provide better incentives than conditional fees independently of whether upfront payments are restricted to be non‐negative or not. Under contingent fees, the attorney uses her information about what is at stake more efficiently. Copyright © 2006 John Wiley & Sons, Ltd.     

Endogenous Social Comparisons and the Internal Organization of Firms

Should workers of a firm be organizationally integrated to realize benefits from benchmarking? Or should they be separated to preclude horizontal social comparisons? This paper highlights a trade‐off that arises if social comparisons in firms are endogenous. We analyze a principal multi‐agent model in which the principal trades off the reduction of agents' risk exposures by use of relative performance evaluation and the thereby induced social comparisons for which agents must be compensated. Contrary to standard theoretical predictions, relative performance evaluation is optimal only if the performance measures are sufficiently correlated relative to the agents' regard for others.

Optimal coordination mechanisms in generalized principal–agent problems

The general principal–agent problem is formulated, in which agents have both private information and private decisions, unobservable to the principal. It is shown that the principal can restrict himself to incentive-compatible direct coordination mechanisms, in which agents report their information to the principal, who then recommends to them decisions forming a correlated equilibrium. In the finite case, optimal coordination mechanisms can be found by linear programming. Some basic issues relating to systems with many principals are also discussed. Non-cooperative equilibria between interacting principals do not necessarily exist, so quasi-equilibria are defined and shown to exist.

Targets and Resources: A Screening Perspective

To secure funding for a project, an agent (informed about the project's type) announces a target output. The principal provides more generous resources for high targets but makes compensation tied to performance relative to the projection. The incentive mechanism is geared towards screening project/agent types for resource disbursement at the ex‐ante stage and motivating appropriate efforts at the interim stage. These dual objectives are embedded in an optimal share contract solution: a pair of startup funds and output share between the principal and agent. The target mechanism's performance is then assessed with respect to implementation of the optimal share contract solution. The focus is on linear contracts for their applicability and practical relevance. Copyright © 2016 John Wiley & Sons, Ltd.     

On optimal real estate commissions

When real estate agent effort is unobservable, home sellers do not prefer the lowest possible commission rate because such a rate does not induce sufficient effort from agents. As a result, the optimal commission from the seller’s perspective exhibits downward rigidity, even if there is free entry. The analysis shows that downward rigidity will occur if and only if the quasi-fixed costs of selling a house are small.     

Transfer of authority within hierarchies

This paper studies delegation and communication in a model of three-tier hierarchy. There is an uninformed principal, and uninformed intermediary, and an informed agent. Under delegation the principal chooses an interval of actions to delegate to the intermediary, and the intermediary chooses a sub-interval from that interval to delegate to the agent. Under communication, the agent communicates with the intermediary, after which the intermediary communicates with the principal. We characterize the equilibrium outcomes under delegation and communication. We show that under delegation the principal can appoint a more biased individual to be the intermediary, and a less biased individual to be the agent. Furthermore, we demonstrate that the principal can prefer to communicate with the subordinates rather than delegate decision rights to them if the intermediary and the agent have opposing biased.     

The effect on housing quality of reducing the structure tax rate

The implicit market approach of Rosen is combined with a dynamic model of producer behavior to determine the conditions under which reducing the structure tax rate leads housing quality to rise. Specifically, it is found that, in the stationary state, quality will rise if capital is a noninferior input. Since it is argued that quality cannot be accurately measured, this conclusion is then tested with an unobservable variables model where quality is the unobservable. A comparison between the responses of quality and housing quantity to reductions in the tax rate is made.     

The hidden costs of control revisited: Should a sanctioning policy be announced in advance?

Sanctions are widely used to enhance compliance in principal agent relationships. Although there is ample evidence confirming the predicted positive incentive effect of sanctions, it has also been shown that imposing sanctions may reduce compliance by crowding out intrinsic motivation. We add to the literature on the hidden costs of control by showing that these costs are restricted to situations where the principal actively chooses to sanction low performance and where this choice is known to the agent. In such a situation, the principal's commitment to sanction low performance might indicate that she or he is a distrustful “type” and hence conveys a negative signal. To the contrary, if (a) an agent is not informed about whether low performance will be sanctioned or if (b) the computer determines whether low performance will be sanctioned, the principal's “type” is not revealed, and we find no evidence of crowding out.     

Stochastic costly state verification and dynamic contracts

I consider a dynamic costly state verification environment in which a risk-averse agent enters into a contract with a risk-neutral principal. The agent has random income which is unknown to the principal but can be verified at a cost. The principal can commit to executing random verifications.I extend the standard recursive methods to study the problem and show that it is optimal to set verification probabilities strictly less than 1. If the agent׳s absolute risk aversion declines sufficiently slowly, the principal will use verification regardless of its cost. If the agent's income is verified then he would get consumption and continuation utility strictly higher than if his income were not verified.     

Relative entropy in sequential decision problems

Consider an agent who faces a sequential decision problem. At each stage the agent takes an action and observes a stochastic outcome (e.g., daily prices, weather conditions, opponents' actions in a repeated game, etc.). The agent's stage-utility depends on his action, the observed outcome and on previous outcomes. We assume the agent is Bayesian and is endowed with a subjective belief over the distribution of outcomes. The agent's initial belief is typically inaccurate. Therefore, his subjectively optimal strategy is initially suboptimal. As time passes information about the true dynamics is accumulated and, depending on the compatibility of the belief with respect to the truth, the agent may eventually learn to optimize. We introduce the notion of relative entropy, which is a natural adaptation of the entropy of a stochastic process to the subjective set-up. We present conditions, expressed in terms of relative entropy, that determine whether the agent will eventually learn to optimize. It is shown that low entropy yields asymptotic optimal behavior. In addition, we present a notion of pointwise merging and link it with relative entropy.     

Fairness in Delegated Bargaining

This article examines whether a principal prefers to hire a fair or a selfish agent. A fair agent cares to some extent for the well-being of other people and thus he also cares for the principal. Therefore, if the agent performs individual work, the principal is always better off to hire a fair agent. However, we show that when a third party with conflicting interests is introduced, it may be advantageous for the principal to hire a selfish agent. The reason is that the selfish agent will be a tough bargainer not only when negotiating his employment contract with the principal but also when dealing with the third party, for example, when selling the principal's product to a buyer.     

Emergence of anti-coordination through reinforcement learning in generalized minority games

In this paper we propose adaptive strategies to solve coordination failures in a prototype generalized minority game model with a multi-agent, multi-choice environment. We illustrate the model with an application to large scale distributed processing systems with a large number of agents and servers. In our set up, agents are assigned responsibility to complete tasks that require unit time. They request servers to process these tasks. Servers can process only one task at a time. Agents have to choose servers independently and simultaneously, and have access to the outcomes of their own past requests only. Coordination failure occurs if more than one agent simultaneously requests the same server to process tasks at the same time, while other servers remain idle. Since agents are independent, this leads to multiple coordination failures. In this paper, we propose strategies based on reinforcement learning that minimize such coordination failures. We also prove a null result that a large category of probabilistic strategies which attempts to combine information about other agents’ strategies, asymptotically converge to uniformly random choices over the servers.
