Regulation,reputation, and environmental risk

This paper examines how preferences for social reputation affect the design of monetary incentives in an efficient mechanism for environmental risk. Our results are a high reputation firm receives less than optimal transfer; the low reputation firm sacrifices information rent.     

A note on optimal procurement contracts with limited direct cost inflation

Laffont and Tirole's [Using cost observation to regulate firms, J. Polit. Econ. 94 (1986) 614-641] pioneering analysis identifies the optimal procurement contract when the supplier can readily inflate his innate production cost without detection. When the buyer has some ability to limit such cost inflation, an alternative contract can outperform the contract identified by Laffont and Tirole. The alternative contract induces substantial pooling, discontinuous production costs and effort supply, and rent that varies non-monotonically with innate cost.     

Dynamic Moral Hazard and Executive Stock Options

This paper shows that the optimal executive compensation scheme in a dynamic moral hazard environment is convex in the firm value. This implies that the optimal contract should include stock options. This is because the private benefit of shirking is increasing in firm value and the manager's utility is concave. Therefore, in contrast to the previous literature that takes stock options in the incentive contract exogenously, we rationalize the optimality of their use endogenously. Moreover, we show that the optimal amount of stock options (restricted stocks) increases with agency cost and the executive's reservation utility, decreases with the degree of risk aversion of the manager, and increases (decreases) with the firm size.     

工业园区废弃物交易生态协作激励机制

在分析工业园区废弃物交易存在资产专用性和不确定性等问题的基础上,通过构建园区废弃物交易生态协作收益模型,分别探讨了社会最优条件下、单期交易条件下和关系契约条件下有助于废弃物交易双方生态协作的最优激励机制安排。研究结果表明:资产专用性和不确定性等导致单期交易下生态协作存在效率损失,此时根据生产效率分配协作租金可最大程度地减少生态协作效率损失;关系契约推动了生态协作效率的提升,利用企业可通过隐藏废弃物在利用环节的价值增值信息以及调节奖励支付规则等获得社会最优条件下的生态协作收益;废弃物交易双方越关注未来的预期收益,废弃物交易中的协作程度越高,废弃物交易双方获取的生态协作收益就越大;废弃物再利用的成本越高,越需要交易双方进行长期协作,越需要对园区进行政策干预。     

Operating efficiency and output insensitive employment contracts for capital management

Summary This paper considers a problem in which an agent is hired to manage a capital investment and subsequently receives private information regarding the productivity of the capital investment. The capital manager must decide whether to invest capital supplied by the firm (the principal), or to divert these investment funds to perquisite consumption. If the manager decides to invest, the manager must then select the level of operating efficiency (productivity) of the capital investment, this latter choice being unobservable and constrained by the (maximal) productivity of the investment. In this setting we demonstrate that the optimal employment contract, from the perspective of the firm hiring the manager, is the contract whichminimizes the dependence of the manager's compensation on firm output. This contract pays the manager a fixed wage whenever output from the investment exceeds the wage and provides the manager with all of the projects rents whenever output falls below this level. Thus, we provide a setting in which fixed wage contracts are the optimal incentive contract even when agents are risk neutral and contracts can be costlessly written on future output.We would like to thank the participants in the Princeton Economics and Finance Workshop and the Ohio State University Finance Workshop for their comments on an earlier draft of this paper.

EFFECTS OF ASYMMETRIC INFORMATION WITHIN A FIRM ON OLIGOPOLISTIC MARKET OUTCOMES

I analyze the implications of the Laffont–Tirole type agency problems on oligopolistic market outcomes. In the model, a firm's marginal cost is decreasing in managerial effort and is subject to an additive shock. Both managerial effort and the realization of the shock are a manager's private information. A firm first offers a menu of contract to its manager, and then competes in the product market. As in the model of single principal and single agent, the incentive contracts implement efforts that are distorted downward relative to full information. In this model, with multiple agency relationships, an additional source for upward distortion of effort emerges as a result of the interaction in the product market. The results are robust to whether firms compete in price or quantity.     

‘To sell or not to sell’: Licensing versus selling by an outside innovator

We study various modes of technology transfer of an outside innovator in a spatial framework when the potential licensees are asymmetric. In addition to different licensing options, we also look into the option of selling the property rights of innovation and find the optimal mode of technology transfer. For licensing we find the optimal policy is to offer pure royalty contracts to both licensee firms when cost differentials between the firms are relatively small compared to the transportation cost, otherwise offer a fixed fee licensing contract to the efficient firm only. Interestingly, we show the innovator is always better-off selling the innovation to any one of the firms who further licenses it to the rival firm. The result holds irrespective of the size of the innovation (drastic or non-drastic) and the degree of cost asymmetry between the licensees. Social welfare is greater under selling than licensing.     

A Note on Franchising and Wage Bargaining

A franchising contract relocates distributable rent between franchisor and franchisee. With decentralized wage bargaining relocation modifies the position of the union in the wage bargaining. If the rent is relocated to the franchisor completely, then even a strong union is not able to raise wage above reservation level in the franchisee's firm. If franchisor and franchisee negotiate on rent division, there is an incentive to increase the franchise fee at the expense of the union. Therefore the overall rent assigned to labor depends on the differences of labor intensity in the franchisor's and franchisee's firms. Firm owners may be able to transfer distributable rents from a firm with a strong union to one with a weak union. Furthermore, a franchising contract shows a first mover advantage. A franchising contract is placed before wage bargaining, benefiting the franchisor.     

Regulating an externality-generating public utility: A multi-dimensional screening approach

In this paper, I present a monopoly screening model in which a firm holds private information on fixed abatement costs. Because of the nature of the optimal contracts, bunching is never optimal even with ‘n’ distinct types. A characterization of full and limited information solutions is offered and it is shown that the design standards alone determine the value of an information rent. The variable charge is completely free of any marginal information costs. This allows the variable charge to track marginal damages and thereby ensures that marginal social costs are covered. A fixed charge implements the optimal solution.     

Optimal employment contracts with bankruptcy constraints

Consider the optimal incentive compatible contract offered by a firm with private information to its risk-averse employees. If the firm is subject to a binding limited liability or bankruptcy constraint then the contract will yield underemployment in low productivity states (relative to full-information efficiency). Such contracts either yield underemployment in all states, or excessively high variability in employment.     

Cooperative interim contract and re-contract: Chandler's M-form firm

Summary. At an interim stage players possessing only their private information freely communicate with each other to coordinate their strategies. This results in a core strategy, which is interpreted as an equilibrium set of players' alternative type-contingent contract offers to their fellows. From this set of offers each player then chooses an optimal one and engages in some subsequent action, thus possibly revealing some private information to the others. Now with new information thus obtained from each other, the players play a new game to re-write their contract. In all of the optimization and gaming just described, Bayesian incentive compatibility plays a central role. These ideas are formulated within a model of a profit-center game with incomplete information which formally describes interaction of the asymmetrically informed profit-centers in Chandler's multidivisional firm.

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.      

Using Market Structure to Regulate a Vertically Integrated Monopolist

A natural monopolist whose cost is private information produces a good which is combined with another good that can be produced by the monopolist or by other firms. The agency that regulates the monopolist can impose any of several different market structures in the industry: integrated monopoly, vertical separation with free entry downstream, or liberalization downstream (both integrated and independent production). When several firms produce downstream, a Cournot quantity-setting game with free entry determines the market price. We derive the optimal contracts to offer the monopolist under all three market structures and examine the influence of downstream cost differences on access prices.We then study the optimal regulatory policy where the regulator can condition the downstream market structure on the monopolist's cost report to the regulator. The optimal regulatory policy awards a monopoly to a low-cost upstream firm, but requires free entry downstream if the monopolist reports high upstream costs. Thus, the choice of market structure is an additional tool to limit rent extraction by the monopolist. Simulation analysis reveals the possibility of significant welfare gains from this additional regulatory tool.     

Monopolistic screening and uninformed buyers

In the standard monopolistic screening problem, buyers obtain information rent as a result of possessing private information; if a contract can be offered before the buyer knows his valuation, the seller can extract the full (expected) surplus. I consider a situation where the buyer may or may not have private information about his valuation at the time the contract is offered. Is the seller (strictly) better off as compared to the standard situation? The answer depends crucially on the specific model. In the 2-types model, unless the probability (that the buyer is uninformed) reaches a critical threshold, the seller is unable to benefit from the buyer's ignorance. In the continuum-types model, on the other hand, optimal expected profit is strictly higher than in the standard model whenever this probability is positive.     

SHARECROPPING,LAND EXPLOITATION AND LAND‐IMPROVING INVESTMENTS*

This paper analyses the tenancy problem in a dynamic setup and addresses two long‐standing issues: inefficiency and lack of investment. It considers the problems that the tenant, with a shorter‐term interest in the farm than the landlord, might overexploit the land to maximize immediate returns even at the cost of future damages, and under‐supply long‐run productivity improving investments in land. I show that the efficient (first‐best) levels of input use and investment can be achieved (both in the steady state and in transition) by a suitable share contract which, by dampening incentives to maximize current returns, addresses the land exploitation problem, and by an appropriate cost allocation rule which can address the investment problem.     

Price discovery and intermediation in linked emissions trading markets: A laboratory study

Many new and proposed emissions trading systems involve multiple countries and regions. The introduction of interregional trading raises questions about how flexible state- or national-level authorities should be in allowing individual firms to trade with firms or authorities in other states or countries. This paper uses laboratory methods to evaluate the efficiency and pricing performance of linking trading across regions at the firm-to-firm level. In one treatment, individual firms trade directly with firms or authorities in other regions. We compare performance in this treatment to an intergovernmental trading treatment, where emissions trading is restricted to occur only between intermediaries. A baseline treatment of autarky, where firms only trade with other firms in their country or region, provides a benchmark to assess the efficiency benefits of allowing linking. Although efficiency and price discovery are both improved by allowing intermediation in linked permit markets, we find that further gains can be realized through direct firm to firm trading. Buyers in high cost regions and sellers in low cost regions benefit the greatest from linking.     

Transferable quotas,enforcement costs and typical firms: An empirical application to the Norwegian trawler fleet

An alternative to traditional regulations of fisheries to avoid rent dissipation is the use of individual transferable quotas (ITQ _s ) where prices in the quota market provide the necessary information to owners of harvest rights to contract with each other. However, even under such a decentralized regime, information on the underlying technology of the fishing vessels is also necessary. First, since most fisheries consist of many interrelated production processes, in order to avoid rent dissipation by discarding wrong output mix etc., the structure of production in the multispecies fishery must be known to design a proper quota system. Second, an ITQ system may create incentives for misreporting by understating the actual catch. This may especially be the case where the expected degree of self-enforcement is low. The paper proposes a way to reduce the information requirements under regulation with asymmetric information by constructing a typical firm and comparing performance for the other vessels to this firm. Based on the typical firm, and if the industry is relatively homogenous, the performance and hence catch of any other firm in the industry can be predicted within a certain range. Further, the paper applies this idea to the Norwegian trawler fleet to assess the production structure in terms of jointness, input-output separability, and the supply and demand elasticities for the fishing firms. This information characterizes the fishery and thus how the quota system may be designed and how to construct a yardstick in order to reduce the enforcement cost under a decentralized regulation of ITQs.The authors would like to thank Trond Bjørndal, Røgnvaldur Hannesson, Ola Flaaten and two referees for useful comments and suggestions.     

ADVERSE SELECTION,LEARNING, AND COMPETITIVE SEARCH

I develop a model that allows for an analysis of the effects of time on adverse selection in the presence of search frictions. I find that, as a firm takes longer to adjust a worker's contract in response to learning about his type, inefficient overwork during the time before wage adjustment (probation) decreases. This provides a rationale for an optimal (minimum) probation period of about one month in the baseline scenario. Optimal probation duration varies with the degree of search frictions, the cost of effort, the relative productivity of different types of workers, and minimum wage regulations.     

Input Prices as Signals of Costs to a Downstream Rival and Customer

We consider a dual distribution channel in which a vertically integrated manufacturer competes with a downstream rival in a retail market and also sells an input to the rival. We use a signalling model with a continuum of types to examine a situation in which the manufacturer has private information on the production cost of its retail product. We show that in a separating equilibrium under Cournot (Bertrand) retail competition, the manufacturer signals the uncompetitiveness (competitiveness) of its firm by charging a smaller input price than the optimal price under complete information.
