Incentive roles of fringe benefits in compensation contracts

The purpose of this paper is to establish a new insight into the potential benefit of fringe benefits used by firms in compensation contracts. We show that fringe benefits have a role to provide incentives and reduce agency costs. In an agency model with moral hazard, we examine the optimal incentive package that involves salary, equity shares, and fringe benefits. Based on the notion that fringe benefits are imperfect substitutes for salary and (weakly) complementary to effort, we show how the optimal package may include an excessive provision of fringe benefits that exceeds the first-best level, and why it involves a distortion towards overconsumption of fringe benefits in terms of the manager's preferences.     

Double Moral Hazard,Monitoring, and the Nature of Contracts

generalized double-sided moral-hazard model, with risk-averse parties who mutually monitor each other (to get a reasonable idea of outcome/effort). The model considers trade-off between monitoring costs and moral hazard costs, which are endogenously determined by the extent of monitoring. Using this model, we formally prove a generalized version of Coase's conjecture – that the optimal contract minimizes the agency and risk costs. We then show how varying assumptions about the feasibility or cost of monitoring of the outcome or the worker's effort lead to different contracts being optimal. The analysis is then used to explain the nature of contracts observed in practice under many different situations. We will give an explanation as to why industrial workers typically work under wage contracts, while share contracts are common in agriculture and will explain why profit sharing is more common for senior managers than for the production workers.

Moral hazard and Marshallian inefficiency: Evidence from Tunisia

We formalize the link between optimal cost-sharing contracts and the production technology in the presence of moral hazard by appealing to several well-known results from duality theory. Building on intuitions from the interlinkage literature, we show that optimal contractual structure is determined by the (i) substitution possibilities that exist between different observable factor inputs, as well as (ii) between these inputs and unobservable effort. We endogenize contractual choice using landlord characteristics as instruments, exploiting the fact that, in our dataset, landlords interact with several tenants and vice versa. The approach is applied to an unbalanced plot-level panel of cost-sharing contracts in a Tunisian village, using a translog representation of the restricted profit function. Contractual terms are found to be a significant determinant of input use and therefore lead to Marshallian inefficiency, while the optimality of the underlying contractual structure is rejected.     

基于企业生命周期的高管 激励契约最优动态配置* ——价值分配的视角

本文基于生命周期和委托代理理论，在价值分配视角下，阐释了生命周期演进过程中高管效用敏感性变化规律以及不同高管激励机制运行特征，构建了高管激励契约最优动态配置方案，并利用中国高科技上市公司2010-2013年的面板数据，对高管激励契约体系对企业价值分配的影响进行了实证检验。研究结果表明，在企业成长期和蜕变期，高管薪酬激励能够有效抑制代理成本；而高管声誉激励机制仅在企业成熟期表现出对代理成本的抑制效应；生命周期各阶段内，控制权激励均未发挥显著的治理作用，相反在蜕变期，控制权沦为高管挖掘私人利益的工具。因此，改善薪酬激励期限结构，提升声誉激励和高管市场约束的持续性，构建高管控制权管理制度体系是实现高管激励契约最优动态配置的必经之路。     

Performance Pay and Adverse Selection*

It is well known in personnel economics that firms may improve the quality of their workforce by offering performance pay. We analyze an equilibrium model where worker productivity is private information and show that the firms’ gain from worker self‐selection may not be matched by a corresponding social gain. In particular, the equilibrium incentive contracts are excessively high‐powered, thereby inducing the more productive workers to exert too much effort and increasing agency costs stemming from the misallocation of effort.     

Regulation of product safety characteristics under imperfect observability

In this paper, we consider the problem of setting minimum safety standards for observable safety characteristics and the proper amount of effort in the production of safety for a product which has some unobservable safety attributes. We formulate a second-best optimum for a regulator, examine the interplay between safety effort and a minimum safety standard, and study how the internalization of excess costs or benefits by a self interested regulator affects the minimum safety standard and the safety effort level. Finally, we present two examples using a utility function which is widely used in the law and economics literature.     

Access to capital in rural Thailand: An estimated model of formal vs. informal credit

This paper analyzes the mechanism underlying access to credit, focusing on two important aspects of rural credit markets. First, moneylenders and other informal lenders coexist with formal lending institutions such as government or commercial banks, and, more recently, micro-lending institutions. Second, potential borrowers presumably face sizable transaction costs in obtaining external credit. We develop and estimate a model based on limited enforcement and transaction costs that provides a unified view of these facts. Based on data from Thailand, the results show that the limited ability of banks to enforce contracts, more than transaction costs, is crucial in understanding the observed diversity of lenders.     

RISK‐SHARING MATCHING AND MORAL HAZARD

In this study we model the endogenous relationship formation between risk‐averse principals and agents in a CARA‐normal framework. Agents exert unobservable efforts to increase mean outputs and reduce risks. We show that risk‐reduction efforts are more important than mean‐increasing efforts in determining the matching patterns. Compared to cases without moral hazard, the agency problem in risk reduction induces more positive‐assortative matchings.     

Second Opinions and Price Competition: Inefficiency in the Market for Expert Advice

We consider a market in which an expert must exert costly but unobservable effort to identify the service that meets the consumer's need. In our model, experts offer competing contracts and the consumer may gather multiple opinions. We explore the incentives that a competitive sampling of prices and opinions provides for experts to exert effort and find that there is a tension between price competition and the equilibrium effort. In particular, the equilibrium fails to realize the second best welfare optimum. An intervention, that limits price competition via price control, increases welfare.     

Efficiency,access, and the mixed delivery of health care services

Universal health systems often rely on both pubic provision and contracting arrangements with private hospitals. This paper studies the optimal mix of public and private provision of health care services. We propose a model in which the regulator acts as athird-party payer, and aims to ensure universal access to treatment at minimal cost. Patients need one unit of medical services and differ in the severity of illness. A private and a public hospital are available. Under incomplete contracts, ownership affects the regulatory constraints and the power of managerial incentives. Only the private manager internalizes profits, and has incentives to reject costly patients and to exert effort in cost reduction. Contracting with the private hospital is optimal when managerial effort is relatively effective in reducing costs. By using the public hospital as a last resort provider, the regulator can ensure access, provide incentives to the private manager, and internalize part of the resulting cost savings. Imposing a no-dumping constraint on the private hospital reduces the power of incentives and is not always optimal.     

BENCHMARKING FOR PRODUCTIVITY IMPROVEMENT: A HEALTH‐CARE APPLICATION*

A methodology is developed and applied to compare the performance of publicly funded agencies providing treatment for alcohol abuse in Maine. The methodology estimates a Wiener process that determines the duration of completed treatments, while allowing for agency differences in the effectiveness of treatment, costs of treatment, standards for completion of treatment, patient attrition, and the characteristics of patient populations. Notably, the Wiener process model separately identifies agency fixed effects that describe differences in the effectiveness of treatment (“treatment effects”), and effects that describe differences in the unobservable characteristics of patients (“population effects”). The estimated model enables hypothetical comparisons of how different agencies would treat the same populations. The policy experiment of transferring the treatment practices of more cost‐effective agencies suggests that Maine could have significantly reduced treatment costs without compromising health outcomes by identifying and transferring best practices.     

Costly Tax Enforcement and Financial Repression

Using an overlapping generations production‐economy model characterized by financial repression, purposeful government expenditures and cost of tax collection, we analyse whether financial repression can be explained by the cost of raising taxes. We show that with public expenditures affecting utility of the agents, modest costs of tax collection tend to result in financial repression being pursued as an optimal policy by the consolidated government. However, when public expenditures are purposeless, the above result only holds for relatively higher costs of tax collection. But, more importantly, costs of tax collection cannot produce a monotonic increase in the reserve requirements. What are critical, in this regard, are the weights the consumer assigns to the public good in the utility function and the size of the government.     

SHORT-TERM CONTRACTS REGULATIONS AND DYNAMIC LABOUR DEMAND: THEORY AND EVIDENCE

We present a dynamic labour demand model where we evaluate the impact of employment regulations on permanent and temporary employment. We consider three different kinds of regulations, namely firing costs, hiring costs and a constraint on temporary contracts. These regulations differently affect the size and composition of employment. The theoretical results are interpreted and questioned on the basis of empirical evidence on the employment effects of the regulation reforms that occurred in the major European countries in the period 1983–1999. The empirical analysis is based on a new set of time‐varying indicators on permanent employment protection, fixed‐term contracts and temporary agency work regulations. We find evidence in support of the hypothesis that fixed‐term contracts have been effective stepping‐stones to permanent jobs during the period under observation. On the contrary, flexible temporary agency work regulations seem to induce a substitution of permanent with temporary contracts.     

Regulation and Contracts for Utility Services: Substitutes or Complements? Lessons from UK Railway and Electricity History

It is frequently suggested that regulation by contract can effectively substitute for regulation by a specialist regulatory agency for utility service industries. We examine these arguments and consider legal aspects and the historical experience of the UK as regards railways and electricity. We conjecture that regulation and contracts are complements for network industries rather than substitutes so that a regulatory agency allows for better and simpler contracts, which are easier to monitor, enforce and revise. This is what would be expected from the theory of incomplete contracts. We demonstrate that UK historical experience is strongly consistent with this view.     

Ownership and Cost‐Sharing Contracts

We discuss the relative merits of public and private ownership in an incomplete contract framework developed by Hart, Shleifer and Vishney (HSV). We add two new elements to their model. First, the government may offer cost‐sharing contracts when procuring the good. Second, the owner of a private firm may divert resources that increase their own profit/utility but increase total costs. The cost sharing contract allows the government to reduce the private firm's incentives to dump quality in order to save on costs. However, this also leads to resource diversion, which increases total costs. We derive the preferred mode of ownership when the government optimally chooses the power of the cost sharing scheme. We find that the presence of quality‐reducing cost reductions only favours government ownership if the scope for resource diversion is substantial. A discussion of when resource diversion is likely to be important is also provided.     

Disease management primer: managing dollars by managing disease

The costliest participants to treat are those with chronic and serious, acute conditions that are often preventable. Developing programs aimed at patients with chronic conditions could be the key to getting control of health care costs. Disease management programs seek to alleviate some of this expense by better managing chronic illnesses and improving the overall health care of employees.     

Complex home care: part III--economic impact on family caregiver quality of life and patients' clinical outcomes

Family caregivers perform a significant role in the care of patients with chronic illnesses and prescribed life-long complex home care treatments. Both quantitative and qualitative data from this study suggest the mental health burdens and financial costs of home parenteral nutrition (HPN) caregiving are extensive. In this study, the variability in HPN out-of-pocket expenses and the uncertainty of incurring such extensive costs created additional financial worries within already stressed families. Based on these data, interventions to improve caregivers' sleepiness, depression, and physical health could be hypothesized to improve both patients' and caregivers' quality of life and reduce the frequency of patients' catheter-related infections. These specific nursing interventions also could improve caregiver health and subsequently reduce the costs of caregivers' health care.     

HOW TO DESIGN INFRASTRUCTURE CONTRACTS IN A WARMING WORLD: A CRITICAL APPRAISAL OF PUBLIC–PRIVATE PARTNERSHIPS*

We analyze how long‐term uncertainty, for example, regarding future climate conditions, affects the design of concession contracts and organizational forms in a principal–agent context, with dynamic moral hazard, limited liability, and irreversibility constraints. The prospect of future, uncertain productivity shocks on the returns on the firm's effort creates an option value of delaying efforts, a course that exacerbates agency costs. Contracts and organizational forms are drafted to control this cost of delegated flexibility. The possibility for the agent to delay investment in response to uncertainty and irreversibility also elicits preference for unbundling different stages of the project through short‐term contracts. Our analysis is relevant to infrastructure sectors that are sensitive to changing weather conditions and sheds a pessimistic light on the relevance of public–private partnerships in this context.     

INCENTIVE CONTRACTS AND TOTAL FACTOR PRODUCTIVITY*

We propose a transactions cost theory of total factor productivity (TFP). In a world with asymmetric information and transactions costs, productivity must be induced by incentive schemes. Labor contracts trade off marginal benefits and costs of effort. The latter include, in addition to the workers' marginal disutility of effort, organizational costs and rents. As the economy grows, contracts change endogenously, inducing higher effort and productivity. Transactions costs are also affected by societal characteristics that determine the power of incentives. Differences in these characteristics may explain cross‐economy productivity differences. Numerical experiments demonstrate the model's consistency with time‐series and cross‐country observations.
