Renegotiation-proof contracting, disclosure, and incentives for efficient investment

Disclosure by firms would seem to reduce investment inefficiency by reducing informational asymmetry. However, the impact of disclosure is endogenous and depends on incentives within the firm. Given optimal renegotiation-proof contracts, disclosing only accepted contracts does not solve the Myers-Majluf problem. What solves the problem is having either full transparency of all compensation negotiations or, more reasonably, additional forward-looking announcements. The model is robust to renegotiation in equilibrium, the order of moves, and moral hazard. The analysis illuminates disclosure regulation: forward-looking disclosure is beneficial when the manager's contract is optimal and induces truth-telling.     

Efficient moral hazard

This paper presents an infinite-horizon, discounted dynamic programming model of the endogenous opportunity costs of an agent’s effort that is allocated among an endogenous number of principals. An agent allocates effort between evaluating new principals and attending to current principals. Since each principal’s return is not maximized by the agent’s optimal allocation, moral hazard occurs in equilibrium. However, since the agent maximizes the total expected value of all undertaken projects, the agent’s allocation of effort is efficient. If the agent chooses a single principal, then moral hazard does not occur and the allocation is efficient. These results are contrary to the inefficient moral hazard results in bilateral principal-agent (P-A) and common agency (C-A) models.     

REPEATED MORAL HAZARD AND CONTRACTS WITH MEMORY: THE CASE OF RISK‐NEUTRALITY*

We consider a repeated moral hazard problem where both the principal and the wealth‐constrained agent are risk‐neutral. In each of two periods, the agent can exert unobservable effort, leading to success or failure. Incentives provided in the second period act as carrot and stick for the first period, so that the effort level induced in the second period is higher after a first‐period success than after a failure. If renegotiation cannot be prevented, the principal may prefer a project with lower returns; i.e., a project may be “too good” to be financed or, similarly, an agent can be “overqualified.”

Wage Bargaining Versus Efficiency Wages: A Synthesis

We construct a model integrating the efficiency wage model of Shapiro–Stiglitz (1984) (SS), with an individual wage bargaining model in the Diamond–Mortensen–Pissarides (DMP) tradition where firms and workers form pairwise matches. We show that when workers may threaten to shirk on the job and there is individual wage bargaining, the wage is always higher and employment lower than in either the SS model, or the (appropriately modified) DMP model. When firms determine workers' efforts unilaterally, efforts are set inefficiently low in the SS model. In the bargaining model, effort is higher, and is first best when the worker non–shirking constraint does not bind. The overall equilibrium allocation may then be more or less efficient than in the SS model, but is always less efficient than in a pure bargaining model with no moral hazard.

Monitoring multiple agents: The role of hierarchies

This paper presents an analysis of principal/multiple-agent problems when there are monitoring possibilities. A principal/owner of a firm has to decide whether or not to employ one or more supervisors who can observe noisy signals on the workers/agents' actions. For both workers and supervisors there is a moral hazard problem. The optimal allocation of monitoring activities and determinants of the decision to hire a supervisor are discussed, and it is explored how multi-level monitoring-hierarchies are structured in such a firm.     

Severe or gentle bankruptcy law: Which impact on investing and financing decisions?

This research investigates how legal sanctions prevailing under bankruptcy may impact on debt contracting and on investing decision. We model firms having the opportunity to engage (or not) faulty management. In case of default, the firms may escape costly bankruptcy by reaching a private agreement with the bank. We show that such renegotiation process may depend on the level of severity of bankruptcy law.Our approach helps in answering the following key questions: can bankruptcy costs always be internalized? Who benefits from accrued severity? Should the creditors accept a certain level of moral hazard from their debtors? Should bankruptcy law be extremely severe in order to ensure ex-ante efficiency? Does such severity depend on the financial environment?The model focuses on three equilibriums. The first equilibrium describes honest firms that choose the best investment project (ex-ante efficiency). Here, we show that bankruptcy costs can be avoided through private renegotiation (ex-post efficiency). Yet, the legislator cannot directly implement this equilibrium as it does not depend on the level of legal sanctions. A second equilibrium describes tricky firms turning to the less profitable and riskiest project. Here, default is still privately resolved: the occurrence of such equilibrium can be avoided owing to a minimal amount of legal sanctions that depend on the level of interest rate. Last, we consider firms that adopt mixed strategies regarding their investment policy. Here, two post-default bargains prevail (pooling or separating) and costly bankruptcy may occur.Simulations illustrate how the bank finally chooses between these equilibriums while the legal environment becomes more severe. For moderate levels of legal sanctions, banks may accept a certain level of faulty management, expecting to take advantage of bankruptcy punishment. An increase in sanctions, however, has a compelling effect on the companies towards honoring their commitments. Once the optimal equilibrium prevails, any additional increase in sanctions is ineffective as the players' strategies no longer depend on the legal environment. As a result, extreme severity is not required to ensure both ex-ante and ex-post efficiencies. Last, we find that a more severe bankruptcy law increases the protection of banks and may result in reduction of the contractual interest rate, which on the other hand benefits the debtors.     

Occupational self-selection in a labor market with moral hazard

This paper studies the determinants and implications of self-selection when firms imperfectly observe worker effort. The effects of the resulting moral hazard problem on the self-selection mechanism are analyzed in a model in which workers simultaneously choose an employment sector and an effort level. The implications of the model reveal that in the presence of moral hazard, workers’ effort decisions become an additional mechanism determining the pattern of selection into sectors. Workers’ sector-specific endowments impact sectoral allocation through their effect on workers’ comparative advantage as well as their effect on workers’ shirking propensity. The model is then used in an empirical application that analyzes workers’ self-selection into white collar and blue collar occupations. The estimation results, based on data from the National Longitudinal Survey of Youth, suggest that workers’ occupational self-selection leads to higher wages and lower dismissal rates in both occupations, compared to an economy in which workers are randomly assigned to each occupation. The difference in dismissal rates between the two occupations is driven by the higher expected productivity in the white collar sector. The positive effects of occupational sorting diminish as the labor market becomes increasingly characterized by moral hazard. Results also suggest that human capital investments in skills that are most relevant to blue collar jobs may generate higher wages and lower dismissal rates in both white collar and blue collar occupations.     

Renegotiation-Proof Dynamic Contracts with Private Information

This paper studies the issue of renegotiation in a model of dynamic moral hazard. I introduce the notion of a renegotiation-proof dynamic contract. I show that the constraint of renegotiation-proofness can have the effect of setting a higher lower bound to the set of attainable expected utilities of the agent. This result extends the notion of “credit rationing” from the static models of optimal contracting to a dynamic setting and is useful for thinking about competition for long-term contracts. This result also has implications for the long-run behavior of the expected utility of the agent under dynamic contracting. Journal of Economic Literature Classification Numbers: 026, 315.     

Trade liberalization, heterogeneous firms and the soft budget constraint

We analyze the interaction between the soft budget constraint (SBC) and international trade by placing Segal’s (1998) SBC model within Melitz’s (2003) framework of international trade with heterogeneous monopolistically competitive firms. As in Segal’s model, SBC may result in moral hazard. The opening to international trade adds another sort of inefficiency. Some firms that would have become exporters in the absence of SBC choose to apply low effort and not export in order to extract a subsidy from the government. This effect takes place when the trade costs are sufficiently low. Overall, however, trade liberalization reduces inefficiencies generated by SBC. The number of firms subject to moral hazard SBC decreases, aggregate effort level increases and aggregate profits lost due to SBC-induced sub-optimal effort decline as trade costs decrease.

Investment and the soft budget constraint in China

This paper examines the incentive effects of the soft budget constraint on the investment behavior of firms in general and on the investment-cash flow sensitivity in particular. To this end, we develop a simple model of moral hazard that takes the soft budget constraint into account. Within this moral hazard environment, we show that investment is positively related to the amount of internal funds. We further show that the presence of the soft budget constraint deteriorates the moral hazard problem, thereby making the investment level less sensitive to the amount of internal funds. This is the case irrespective of whether the soft budget constraint renders the firm more or less liquidity constrained. To test the model's empirical implications, we employ data of China's listed companies for the period from 1997 to 2003. We use the share of state ownership as a proxy for the severity of the soft budget constraint. We find strong evidence that firms with larger shares of state ownership exhibit lower investment-cash flow sensitivities than firms with smaller shares of state ownership.     

On the design of incentive schemes under moral hazard and adverse selection

This paper characterizes a class of optimal incentive schemes in a simple principal–agent model which allows for moral hazard and adverse selection. We show that incentive compatible allocation can always be (approximately) implemented through a menu of quadratic incentive schemes. It is also proved that the set of incentive compatible allocations is independent of the distribution of the additive uncertainty which affects the outcome. Informational requirements and economic interpretation of quadratic and linear schemes are discussed.     

Managerial Compensation and the Cost of Moral Hazard

This article investigates managerial compensation and its incentive effects. Our econometric framework is derived from a multiperiod principal-agent model with moral hazard. Longitudinal data on returns to firms and managerial compensation are used to estimate the model. We find that firms would incur large losses from ignoring moral hazard, whereas managers only require moderate additional compensation for accepting a contract that ties their wealth to the value of the firm. Thus the costs of aligning hidden managerial actions to shareholder goals through the compensation schedule are much less than the benefits from the resulting managerial performance.     

Relational Incentives and Moral Hazard in Teams

This paper studies moral hazard in teams using a model where efforts are promoted via the combination of profit shares and relational contracts. The focus is on how these two forms of incentives interact. According to the degree of effort observability and the importance of future interaction, the optimal allocation of profit shares can range from a wide dispersion across players to a full concentration of shares in the hands of a single player. When shares are sufficiently concentrated, the corresponding residual claimant can also adopt the role of administering all relational contracts, therefore serving as an endogenously chosen principal.     

Debt, collateral, and renegotiation under moral hazard

This paper demonstrates that renegotiation will increase initial collateral requirements in debt contracts under moral hazard. Hence, it confirms Smith and Warner's conjecture that severity of contractual covenants and ease of renegotiating debt contracts are positively related, in case where the covenant provision is collateral.     

Renegotiation in agency contracts, menus vs. simple contracts

The literature on contracts has shown that renegotiation in agency relationships generates efficiency losses when the principal leads the renegotiation. We show that contractual incompleteness may reduce such efficiency loss. This provides an explanation to the widespread use of simple contracts. We further point at the limited liability of the agent as a source of inefficiency when he leads the renegotiation; this latter result tempers the irrelevancy of contractual incompleteness demonstrated earlier in the literature.

ROLE OF RELATIVE AND ABSOLUTE PERFORMANCE EVALUATIONS IN INTERGROUP COMPETITION

We investigate the moral hazard problem in which a principal delegates multiple tasks to multiple workers. The principal imperfectly monitors their action choices by observing the public signals that are correlated with each other through a macro shock. He divides the workers into two groups and makes them compete with each other. We show that when the number of tasks is sufficiently large, relative performance evaluation between the groups accompanied by absolute performance evaluation results in eliminating unwanted equilibria. In this case, any approximate Nash equilibrium nearly induces the first‐best allocation.
