Information, bilateral negotiations, and worker recruitment

This paper studies experimentally how firms choose between using a centralized market and bilateral negotiations to recruit new personnel. In the market firms interact with several workers but do not have information about workers’ behavior in the past. In the bilateral negotiations firms negotiate bilaterally with prospective workers and learn about workers’ performance in previous jobs. We show that the interaction between social preferences, the incompleteness of contracts and the existence of information about a worker’s past performance provides an explanation for firms forgoing market opportunities and bilaterally negotiating with a worker. We observe that approximately 30% of all job contracts were bilaterally negotiated when these contracts are incomplete as opposed to only 10% when contracts were complete. The surplus from trade is higher when incomplete contracts can be bilaterally negotiated, which can be attributed to the presence of information.     

Delivered pricing and endogenous delegation of contract type

This article demonstrates for the first time that owners will delegate the location decision under delivered pricing using a relative performance contract rather than a market share contract. It goes on to evaluate the welfare consequences of this demonstration. With linear production costs and simultaneous location, both incentive contracts reduce welfare, but the chosen relative performance contract reduces it by less. Yet, with linear costs and sequential location, the chosen relative performance contract reduces welfare by more. Finally, with enough convexity in production costs, welfare can be improved by the chosen relative performance contracts.     

Incentive contracts and bank performance

This paper, using unique survey data from the banking industry in rural China, investigates the effect of incentive contracts on performance. In the context of China's economic transition, we find that the incentive contracts have a positive effect on the bank manager's performance in deposit taking and non‐performing loan reduction. This finding is robust when we control for the endogeneity of incentive contracts. Our empirical results present evidence on the positive effects of incentive‐based banking reforms in rural China.     

我国上市公司经理人激励的业绩基础选择性实证研究

以我国上市公司为样本对经理人激励的业绩基础选择问题进行了实证检验。研究发现目前我国上市公司经理人报酬契约只倚重会计业绩指标,而将市场业绩指标和相对业绩指标排除在报酬契约之外,这极易导致经理人行为的短期化,提高代理成本,降低上市公司的运作效率。因此,必须调整上市公司经理人的报酬结构,建立基于会计业绩的短期激励与基于市场业绩的长期激励相结合的经理人报酬激励机制。     

The response to incentives and contractual efficiency: Evidence from a field experiment

We use data from a field experiment to estimate worker reaction to incentives and the optimality of piece-rate contracts. Our estimate of the elasticity of output with respect to piece rates is 0.39. Regression methods cannot predict performance under hypothetical contracts. Therefore, we apply structural econometric methods (without imposing profit maximization) to evaluate observed-contract optimality. Using profit as a metric, we estimate the distance between observed and profit-maximizing contracts to be negligible. This suggests that observed contracts closely approximate optimal contracts under asymmetric information about worker ability. Under complete information, the firm could increase expected profits by 14 percent keeping workers indifferent to the observed piece-rate contract. Profits could increase between 44 and 49 percent if the firm exploited information about ability to reduce worker utility to the outside alternative.     

Inequity Aversion and Team Incentives

We study optimal contracts in a simple model where employees are averse to inequity, as modeled by Fehr and Schmidt (1999) . A "selfish" employer can profitably exploit envy or guilt by offering contracts which create inequity off-equilibrium, i.e., when employees do not meet his demands. Such contracts resemble team and relative performance contracts. We derive conditions for inequity aversion to be in itself a reason to form work teams of distributionally concerned employees, even in situations in which effort is contractible.     

Optimal incentive contracts under inequity aversion

We analyze the classic moral hazard problem with the additional assumption that agents are inequity averse. The presence of inequity aversion alters the structure of optimal contracts. When the concern for equity becomes more important, there is convergence towards linear sharing rules. The sufficient statistics result is violated. Depending on the environment, contracts may be either overdetermined, i.e. include non-informative performance measures, or incomplete, i.e. neglect informative performance measures. Finally, our model delivers a simple rationale for team based incentives, implying wage compression.     

Limited observability as a constraint in contract design

Limited observability is the assumption that economic agents can only observe a finite amount of information. Given this constraint, contracts among agents are necessarily finite and incomplete in comparison to the ideal complete contract that we model as infinite in detail. We consider the extent that finite contracts can approximate a complete contract. The objectives of the paper are: (i) to identify properties of agents’ preferences that determine whether or not finiteness of contracts causes significant inefficiency; (ii) to evaluate the performance of finite contracts against the ideal optimal contract in a bilateral bargaining model.     

长期视角下股权激励的动态效应研究

基于长期研究视角,本文在考察股权激励对企业绩效动态影响的基础上,检验了产权性质、授予动机和实施频率对这一关系的影响。结果显示：股权激励存在动态激励效应。不仅在实施当期具有即期影响,在实施后的五年还表现出持续性的激励效果,且在时间分布上呈现出先升后降的“倒U型”特征。相较于民营企业,国有企业实施股权激励后的绩效提升作用较弱,持续期较短,且在实施初期没有即刻显现出激励效应,而是经历了一个为期两年的滞后期。相较于绩效提升作用更强、更持久的激励型契约,福利型合约仅在短期内存在激励效果,并在实施后第四年出现业绩反转,显现出负效应。相对于只实施了一期的公司,股权激励对连续实施多期激励计划公司的激励效果更好,不仅绩效提升作用更强,激励效应也更持久、稳定。     

Collective Organizations versus Relative Performance Contracts: Inequality, Risk Sharing, and Moral Hazard

This paper studies collective economic organizations that share risk and mitigate moral hazard and compares them with relative performance contracts. Information-constrained optimal distributions of organizations and contracts are shown to be functions of the underlying primitives, in particular, the distribution of Pareto weights, and hence degree of inequality. Internal inequality of a potential, local group is a force for collective organization. That is, multi-agent organizations exist in order to extract wealth from some but not necessarily all members. The group organization is also shown to be information-constrained Pareto optimal at extremes of local wealth relative to an outsider. But the group organization is susceptible to both agents simultaneously deviating, colluding against the outsider, and this distortion makes an individualistic, relative performance contract an attractive alternative. More generally, organizations, contracts, and allocations are jointly determined. These implications could be distinguished in cross-sectional, time series data.

Procurement contracting: efficiency,renegotiation and performance evaluation

Renegotiation of long-term contracts can result in inefficiency if it is associated with strategic behavior that reduces the reliability of ex ante agreements. The focus of this paper is on the consequences of opportunistic renegotiation of procurement contracts, and the subsequent performance evaluation, when commitment is limited and information is incomplete or verifiability is limited. Performance data that would indicate efficiency in a complete information setting may indicate inefficiency in an incomplete information setting. Performance evaluation thus should focus on procurement mechanisms that relate the quantity purchased to the possible costs of the supplier.     

Golden cages for showy birds: Optimal switching costs in labor contracts

Under what circumstances do workers sign contracts with high quitting penalties? Our answer points to market transparency. When the worker's performance is privately observed by the incumbent firm, alternative employers face an adverse selection problem. As a result, efficient separations can only take place through involuntary layoffs and there is no role for quitting fees. In contrast, when performance is public, quitting fees are useful devices to appropriate the surplus from workers’ reallocation. Separations are amicable and take the form of quitting after downwardly renegotiating the fees. Qualitative features of contracts are independent of the distribution of ex-post bargaining power. The impact of switching costs on total welfare and its distribution depends on the degree of market transparency and the ex-ante distribution of market power.     

A simple explanation of the relative performance evaluation puzzle

We study a simple moral hazard model in which two risk-neutral owners establish incentives for their risk-averse managers to exert effort. Because the probability distributions over output realizations depend on a common aggregate shock, optimal contracts make the compensation of each manager contingent on own performance but also on a performance benchmark—the performance of the other firm. If the marginal return of effort depends on the aggregate state, optimal contracts are not monotonically decreasing in the performance benchmark. This provides a simple explanation of the Relative Performance Evaluation (RPE) Puzzle—the documented lack of a negative relationship between CEO compensation and comparative performance measures, such as industry or market performance. Our simple model can also explain one-sided RPE—the documented tendency to insulate a CEO's rewards from bad luck, but not from good luck. We clarify that our results are robust in several dimensions and we discuss other applications of our findings.

Moral Hazard and Adverse Selection in Procurement Contracting

A model of procurement contracting is developed and tested in laboratory experiments. Market performance results are presented for both fixed-price and cost-sharing contracts. Contracts are awarded with first-price sealed-bid or second-price sealed-bid auctions. The environment contains post-auction cost uncertainty and opportunity for unmonitored effort in contract cost reduction. Cost-sharing contracts are found to reduce procurement expense but also to be inefficient because of their induced moral hazard waste and cost overruns.Journal of Economic LiteratureClassification Numbers: C72, C92, D44, D61, D82, H57, L14.     

Contracts and competition: an introduction

Changes in public policy and corporate strategy have enhancedthe role of contracts as mechanisms of economic governance.The understanding that norms, standards and other forms of regulatorymechanism can affect the structure of incentives and the qualityof contractual outcomes has helped to stimulate a wider debateconcerning institutions and economic performance. Among thethemes explored in this Special Issue, which draws on the UKESRC's Contracts and Competition Programme, are the need forinterdisciplinary analysis of economic organisation; the linkbetween contracts and trust; and the complex relationship betweeninstitutional forms and economic outcomes.     

Asymmetric contracts,cash flows and risk taking of mutual funds

Fund managers in delegated portfolio management face asymmetries in their compensation contracts and in the fund flows contingent on their funds' performance relative to a benchmark. In this study we investigate the impacts of contract asymmetry and fund flow asymmetry on the risk-taking behavior of open-end funds whose delegation contracts are performance based, and show that their impacts are opposite. When the two asymmetries apply simultaneously, the impact of one on the fund's risk-taking alleviates the impact of the other. Raising the return-sharing ratio cannot make the manager take more risk, but increasing the cash flow volume can. We also show that the tracking-error variance can measure the degree of risk that the fund takes.     

Explicit versus implicit contracts for dividing the benefits of cooperation

Experimental evidence has accumulated highlighting the limitations of formal and explicit contracts in certain situations, and has identified environments in which informal and implicit contracts are more efficient. This paper documents the superior performance of explicit over implicit contracts in a new partnership environment in which both contracting parties must incur effort to generate a joint surplus, and one (“strong”) agent controls the surplus division. In the treatment in which the strong agent makes a non-binding, cheap talk “bonus” offer to the weak agent, this unenforceable promise doubles the rate of joint high effort compared to a baseline with no promise. The strong agents most frequently offered to split the gains of the high effort equally, but actually delivered this amount only about one-quarter of the time. An explicit and enforceable contract offer performs substantially better, increasing the frequency of the most efficient outcome by over 200% relative to the baseline.     

Risking Other People's Money: Experimental Evidence on the Role of Incentives and Personality Traits

Decision-makers often face incentives to increase risk-taking on behalf of others (e.g., they are offered bonus contracts and contracts based on relative performance). We conduct an experimental study of risk-taking on behalf of others using a large heterogeneous sample, and we find that people respond to such incentives without much apparent concern for stakeholders. Responses are heterogeneous and mitigated by personality traits. The findings suggest that a lack of concern for others’ risk exposure hardly requires “financial psychopaths” in order to flourish, but it is diminished by social concerns.     

Court Efficiency and Procurement Performance

Disputes over penalties for breaching a contract are often resolved in court. A simple model illustrates how inefficient courts can sway public buyers from enforcing a penalty for late delivery in order to avoid litigation, thereby inducing sellers to delay contract delivery. By using a large dataset on Italian public procurement, we empirically study the effects of court inefficiency on public work performance. Where courts are inefficient, we find the following: public works are delivered with longer delays; delays increase for more valuable contracts; contracts are more often awarded to larger suppliers; and a higher share of the payment is postponed after delivery. Other interpretations receive less support from the data.
