Implicit contracts with effort incentives

The model combines the principal-agent approach with the analysis of labor contracts under demand uncertainty. Given the necessity to impose effort incentives the optimal contract is shown to maintain an efficient insurance with respect to the demand uncertainty and the employment risk. However, this efficient insurance may now yield either voluntary or involuntary layoff unemployment. Further, the optimal effort levels entail “underemployment” given adominant strategy incentive mechanism as well as under aNash-equilibrium mechanism. In contrast, the optimal employment levels fall short of achieving efficient production only in the latter case.     

Hidden underemployment among Irish farm holders 2002–2011

This article examines the scale of hidden underemployment on Irish farms from 2002 to 2011. We provide a measure of hidden underemployment that is not captured by the national-level statistics. Hidden underemployment can be attributed to a number of factors relating to inadequate employment situations as described at the 16th International Conference of Labour Statisticians such as low productivity, the poor utilization of skills and other factors specific to agriculture. We place particular attention upon the potential role of off-farm labour supply in solving the underemployment problem. We utilize a two-stage residual inclusion model and a random effects probit model to examine the forces behind farm underemployment. We utilize a fixed effects model to examine the factors driving the severity of farm underemployment. Our findings suggest that instances of hidden underemployment increased between 2002 and 2011. Hidden underemployment appears to be a stubborn problem and is related to the absence of off-farm employment, low yield, livestock intensity and smaller than average farm size in the sheep and drystock cattle sectors in particular.     

Strategic incentive in mixed oligopoly

This paper develops a two stage game model with two competing firms in a mixed oligopolistic market, a public firm and a private firm, and only the public firm giving its manager an incentive contract. The paper presents three types of public firm owner’s objective function and each objective function corresponds to three types of delegation, either of a profit-revenue type, or of a relative performance, or, finally, of a market share one. In an equilibrium, the public firm owner has a dominant strategy to reward his manager with an incentive contract combining own profits and competitor’s profits. Different from Manasakis et al. (2007), this paper suggests that the dominant strategy of the public firm owner is to reward his manager with a profit-revenue type of contract or a market-share type of contract, that is to say profit-revenue is identical with market-share. Using relative-performance type of contract will move the manager away from the owner’s true objective function when the public firm owner only pursues maximizing the social welfare. The private firm will be crowded out and the public firm is the only producer of the market. Under profits-revenues type of contract, the owner’s objective of maximizing the summation of the profit and consumer surplus leads the manager more aggressive. Different combinations give us different results. By comparing the results, each type of incentive contract is an owner’s best response to his decision.     

How to allocate forward contracts: The case of electricity markets

Several regulatory authorities worldwide have imposed forward contract commitments on electricity producers as a way to mitigate their market power. In this paper we analyze the impact of such commitments on equilibrium outcomes in a model that reflects important institutional and structural features of electricity markets. We show that, when firms are asymmetric, the distribution of contracts among firms matters. In the case of a single dominant firm, the regulator can be confident that allocating contracts to that firm will be pro-competitive. However, when asymmetries are less extreme, certain contract allocations might yield anti-competitive outcomes by eliminating more competitive equilibria. Our analysis thus suggests that forward contracts should be allocated so as to (virtually) reduce asymmetries across firms.     

Wage-rise contract and endogenous timing in international mixed duopoly

This paper examines an endogenous-timing mixed model, where a public firm competes against a foreign private firm. Each firm first chooses the timing for adopting a wage-rise contract as a strategic instrument. The following situation is considered. In the first stage, each firm simultaneously and independently chooses the stage in which it adopts a wage-rise contract, namely either stage 2 or stage 3. In the second stage, the firm choosing stage 2 can adopt the wage-rise contract in this stage. In the third stage, the firm choosing stage 3 can adopt the wage-rise contract in this stage. At the end of the game, each firm simultaneously and independently chooses its output. The paper discusses the equilibrium of the endogenous-timing mixed model.     

Short or long-term contract? Firm’s optimal choice

This article studies the behaviour of a firm searching to fill a vacancy. The main assumption is that the firm can offer two different kinds of contracts to the workers, either a short-term contract or a long-term one. The short-term contract acts as a probationary stage in which the firm can learn about the worker. After this stage, the firm can propose a long-term contract to the worker or it can decide to look for another worker. We show that, if the short-term wage is fixed endogenously, it can be optimal for firms to start a working relationship with a short-term contract, but that this policy decreases unemployment and welfare. On the contrary, if the wage is fixed exogenously, this policy could be optimal also from a welfare point of view.     

IMPLICIT CONTRACTS, TRADE UNIONS AND INVOLUNTARY UNEMPLOYMENT

Implicit contract theory is used to predict the nature of optimal wage-employment contracts between a firm and a union with a utilitarian maximand, under an uncertain revenue product of labour. By allowing recruitment of outsiders in good states, and allowing unemployment of union members in bad states, a rich set of possible trajectories in wages and employment is achieved. Monotonicity of employment in prices is preserved, whereas monotonicity of wages is not.     

LONG‐TERM AND SHORT‐TERM CONTRACT IN A MIXED MARKET*

With a two‐period mixed oligopolistic framework, this paper analyses the interaction between the length of incentive contracts and market behaviour. Assuming an environment in which firms choose either a long‐term or short‐term contract, we examine how contracts differ between public and private firms. The results show that the contracts would differ completely among firms; public firm prefers to make a short‐term contract while private firm makes a long‐term contract.     

基于代工合约的企业“哑铃型”经营模式

利用联合决策的博弈模型,针对是否存在信息泄漏,分两种情况对代工合约进行分析。结果发现:在存在信息泄漏的情况下,代工企业的"敲竹杠"行为会使品牌企业与代工企业无法建立长期、稳定的代工关系,此时品牌企业若采取"哑铃型"经营模式可能会出现经营失败。最后,从理论上阐明了建立长期、稳定的代工合约关系的条件,以及处于连续性生产行业的部分企业不能采用"哑铃型"经营模式的原因。     

Endogenous Choice of Strategic Contracts in a Mixed Duopoly with Bargaining Over Managerial Delegation Contracts

We revisit the endogenous choice problem of strategic contracts for the public firm and the private firm in a managerial mixed duopoly with differentiated goods. We consider the situation wherein the managerial delegation contracts are determined by maximising social welfare within the public firm, which is equal to the objective function of its owner, and through bargaining over the content of managerial delegation contracts between the owner and manager within the private firm. We show that, in equilibrium, when the manager of the private firm has high bargaining power relative to that of the owner, the public firm chooses a price contract, while the private firm chooses a quantity contract. However, there is no equilibrium market structure under the pure strategic contract class when the manager has sufficiently low bargaining power relative to that of the owner.     

Regulating a risk-averse firm under incomplete information

We examine the optimal regulatory policy for a risk-averse firm when the firm is imperfectly informed about its efficiency parameter for a project at the time of contracting. The firm’s risk aversion shifts the optimal regulatory policy from a fixed-price contract to a cost-plus contract. The optimal regulatory policy entails undereffort by an inefficient firm as in Laffont and Tirole (J Polit Econ 94(3):614–641, 1986) and the effort distortion increases as the firm becomes more risk-averse. Further, the regulator benefits from sequential contracting with the firm where the firm chooses contract terms gradually as it acquires information, albeit the benefit diminishes as the firm becomes more risk-averse.      

Optimal Forestry Contracts under Asymmetry of Information

In this paper, I analyze optimal royalty contracts in forestry when the harvesting firm has private information on the cost of harvesting. This infinite horizon forest rotation model with asymmetry of information on the cost parameter results in a dynamic incentive problem. Depending on whether the costs are correlated over time or not, the firm either receives rent or receives no rent, associated with the continuation part of the rotation choice. I characterize the optimal contract explicitly in both cases. I also examine the loss in expected welfare surplus resulting from the use of a linear contract instead of the more general non‐linear contract.     

Efficient Private Production of Public Goods under Common Agency

A private, profit-maximizing firm produces a public good that enters the utility functions of several users. Each of them separately designs and proposes to the firm a contract specifying a transfer payment as a function of the amount of public good supplied. The firm has to accept or to refuse each contract before knowing the realized value of a random variable that enters its cost function. We study the Nash equilibria of this game and explore some refinements ruling out Pareto inefficient equilibria.Journal of Economic LiteratureClassification Numbers: C72, H41.     

Choosing Price or Quantity? The Role of Delegation and Network Externalities in a Mixed Duopoly

This paper considers a differentiated goods managerial mixed duopoly composed of one social welfare‐maximising public firm and one profit‐maximising private firm. We model the firm choice of the strategic contract. We find that when the strength of network effects is sufficiently strong, the price competition can become the unique equilibrium market structure. Furthermore, we show that there exists an area of the degree of product differentiation and the strength of network effects such that the situation wherein the public firm chooses its price contract whereas the private firm chooses its quantity contract can become the unique equilibrium structure.     

"企业契约论"的局限性

“企业契约论”把企业本质理解为只是一种契约的认识存在逻辑解释的局限性。问题的症结就在于这一理论的创始者科斯误解了企业取代的对象。企业取代的真正对象其实不是市场而是单干经济。因此，企业本质是一种包含有要素市场交易合约的特殊团队生产。     

Price or Quantity? A New Irrelevance Result for Mixed Markets

Earlier studies for mixed markets have established a series of so‐called irrelevance results. While previous results relate to the attainment of the first‐best allocation for welfare, we provide a new irrelevance result in terms of the choice of strategic variable in the product market. We show that regardless of whether a public or private firm is the market leader, the leader always chooses the price contract whereas the follower is indifferent between the price contract and the quantity contract. The identity of the leader and the follower firm is therefore irrelevant for the equilibrium mode of competition. Implications for economic models in mixed market settings emerge, which are also discussed.     

The effects of imperfect auditing on managerial compensation

We study the optimal shareholder–manager contract having the property to induce the manager to exert high effort and truthfully reveal firm performance. This contract design problem is solved under the assumption of imperfect auditing, either because of mistakes or because of collusion between managers and auditors. The imperfection of the audit technology is costless up to a threshold, beyond which it causes a distortion in the incentive compatible contract or even prevents its existence. This result may help explain the observed decline in the use of stock options, tracing it back to an unfocused activity or poor performance of auditors.     

Flexible Labour,Firm Performance and the Dutch Job Creation Miracle

Unlike internal (‘functional’) forms of flexibility of labour, external (‘numerical’) forms of flexibility (i.e. high shares of people on temporary contract or a high turnover of personnel) yield substantial savings on a firm’s wage bill. Savings on wage bills lead to higher job growth, but do not translate into higher sales growth. Externally flexible labour appears to be related to lower labour productivity growth, the effects being different for innovating vs non‐innovating firms. We discuss these findings from firm‐level and worker‐level data against the background of the Dutch job creation miracle during the 1980s and 1990s. Modest wage increases and flexibilization of labour markets may indeed create lots of jobs. However, this is likely to happen at the expense of labour productivity growth, raising serious doubts about the long‐run sustainability of a low‐productivity–high‐employment growth path.     

Labour contracts in a stock market economy

In this paper, labour contracts are examined in the context of a general stock market economy where all shareholders are risk averse, and firms act in shareholders interest. The problem considered is whether some firm can offer a wage contract that will make all its shareholders better off. We show by example that, contrary to the arguments in the partial equilibrium framework, it is possible that no such contract will exist, even when there are potential gains to risk sharing. A sufficient condition for the existence of a feasible pareto improving contract is given. It is shown that contract trading will arise provided some firm has no large shareholders.
