Optimal Incentives in a Principal-Agent Model with Endogenous Technology

One of the standard predictions of the agency theory is that more incentives can be given to agents with lower risk aversion. In this paper, we show that this relationship may be absent or reversed when the technology is endogenous and projects with a higher efficiency are also riskier. Using a modified version of the Holmstrom and Milgrom’s framework, we obtain that lower agent’s risk aversion unambiguously leads to higher incentives when the technology function linking efficiency and riskiness is elastic, while the risk aversion–incentive relationship can be positive when this function is rigid

Institutional Structure in Corporate Agriculture

In this dissertation, a state-contingent, principal-agent model is developed to examine the institution of input provision by a corporate firm that contracts with agents for the production of a given commodity. "Input provision" entails not only the provision and delivery of key inputs by the principal but also their purchases (or in-house production), as well as contract design to ensure their optimal use. The provision of key inputs is modeled in the context of production contracts for poultry and pork, such as those offered by Perdue Farms, Smithfield Foods, and Tyson Foods in the United States. The decision in question is the levels of inputs (e.g. feed, medication) that the contracting company provides to the farmer. This decision is endogenous to the model, and facilitates comparison of production contracts (input provision) with marketing contracts (no input provision, with all inputs purchased and/or provided by the farmer himself). The theoretical model formalizes Coase's idea that an institutional arrangement emerges if the benefits associated with it exceed the costs. In particular, I characterize the case of no input provision as a corner solution for the optimal choice of inputs provided. The extent of input provision, in turn, reflects "limits to firm size". I also examine conditions under which incentives relating to one of two output dimensions (produced by the agent) tend to zero, when both dimensions are observable and verifiable. The state-contingent approach is used as it allows for a general production technology, and the inclusion of transaction costs in a general theoretical model. The possibility of reservation utility being endogenous in dyadic relationships is also examined. This is explored formally by incorporating pre-contract interactions in a contractual framework with the principal and the agent competing as independent producers prior to contracting. Investment decisions of the principal in this framework favorably impact his variable costs both as an independent producer and as the principal party to a contract. I show that the higher these benefits, the stronger is the incentive for the principal to decide in favor of higher initial investment levels and realize a more competitive position vis-à-vis the smaller producer

Agency and Anxiety

In this paper, we introduce the psychological concept of anxiety into agency theory. An important benchmark in the anxiety literature is the inverted-U hypothesis which states that an increase in anxiety improves performance when anxiety is low but reduces it when anxiety is high. We consider a version of the Holmstrom-Milgrom linear principal-agent model where the agent conforms to the inverted-U hypothesis and investigate the nature of the optimal linear contract. We find that although high-powered incentives can be demotivational, a profit-maximizing principal never offers them. In contrast, the principal may optimally engage in a demotivational level of monitoring. Moreover, since risk can be motivational, the principal may refrain from eliminating it even when monitoring is costless. Indeed, the principal may even add pure noise to the contract in order to motivate the agent, contradicting the informativeness principle. Finally, incentives and monitoring can be strategic substitutes or complements in our model.

Endogenous Verifiability and Optimality in Agency: A non-contingent approach

In the context of a principal-agent model where verification of an agent’s effort is endogenously determined through strategic interactions between contracting parties, we derive a necessary and suficient condition to achieve the first best with a non-contingent or incomplete contract. These conditions relate the Principal’s benefit, the Agent’s cost, the probability of winning and the cost of litigation. Also, these conditions are found to be more general than the ones established in Ishiguro (2002) within a similar setup.incomplete contracts, endogenous verifiability, expectation damages.

Optimal Auctions with Information Acquisition

This paper studies optimal auction design in a private value setting with endogenous information acquisition. First, we develop a general framework for modeling information acquisition when a seller wants to sell an object to one of several potential buyers who can each gather information about their valuations prior to participation. We then show that under certain conditions, standard auctions with a reserve price remain optimal, but the optimal reserve price lies between the mean valuation and the standard reserve price in Myerson (1981). We provide sufficient conditions under which the value of information to the seller is positive, and also characterize the necessary and sufficient conditions under which equilibrium information acquisition in private value auctions is socially excessive. The key to the analysis is the insight that buyer incentives to acquire information become stronger as the reserve price moves toward the mean valuation.optimal auctions, information acquisition, rotation order, informational efficiency

Efficient Contracts for Digital Content

This paper analyses efficient contracts for digital content, focusing on the music industry. It contributes to the quest for an efficient intellectual property rights environment for information goods. Moreover, it adds an interesting application to the field of behavioural economics. The model is set in a contract theory framework with the copyright holder being the principal and a consumer the agent. We offer three contract cases for analysis: strong copy protection, a strategically low price and voluntary reciprocal contributions. Insights from the economics of information and behavioural economics - information goods have public goods properties; social preferences are significant among individuals - are applied to examine the value of a strict copyright enforcement in the digital age. We find that endogenous incomplete contracts based on fair, reciprocal behaviour may achieve a first-best allocation of information goods, while complete contracts are limited to second-best results.internet, music industry, social preferences, reciprocity, moral hazard, file sharing

Does Competition Favor Delegation?

This paper studies the consequences of product-market competition on firms' decisions to delegate more or fewer decision-making responsibilities to managers. By simultaneously addressing the choice of both competitive actions and organizational design, the paper makes an attempt at bringing economic theory and management strategy closer together. An increase in substitutability between the products of the different firms triggers a different response depending on the size of the firm: larger firms delegate more responsibility, whereas smaller firms centralize decision making. The increase in substitutability also causes some firms to exit the market, which pushes in the direction of reduced managerial autonomy. Stronger competition also leads to less discretion in markets in which the possibilities for product differentiation are important. For a given number of firms, an increase in market size increases centralization, as the owner of the firm finds it more costly to accept rent seeking by the managers. However, this increase in market size will lead to the entry of more firms, which calls for more decentralized decision making. Under reasonable conditions, the aggregate effect leads to a U-shaped relationship where firms in both small and large markets are characterized by high levels of discretion, while there is less discretion for intermediate market sizes. Finally, a reduction in entry barriers leads unambiguously to an increase in the level of discretion given to the agent, as it results in a larger number of firms entering the market and, for a given market size, in lower concentration or expected firm-level demand, which reduces the value of having control and pushes in the direction of increased autonomy.product-market competition, delegation, authority, oligopoly, firm organization

Relying on the agent in charge of production for project evaluation

I study the optimal project choice when the principal relies on the agent in charge of production for project evaluation. The principal has to choose between a safe project generating a fixed revenue and a risky project generating an uncertain revenue. The agent has private information about the production cost under each project but also about the signal regarding the profitability of the risky project. If the signal favoring the adoption of the risky project is goods news to the agent, integrating production and project evaluation tasks does not generate any loss compared to the benchmark in which the principal herself receives the signal. By contrast, if it is bad news, task integration creates an endogenous reservation utility which is type-dependent and thereby generates countervailing incentives, which can make a bias toward either project optimal. Our results can offer an explanation for why good firms can go bad and a rationale for the separation of day-to-day operating decisions from long-term strategic decisions stressed by Williamson.Information flows, countervailing incentives, multitasking, asymmetric information, innovations

Monitoring and Pay: An Experiment on Employee Performance under Endogenous Supervision

We present an experimental test of a shirking model where monitoring intensity is endogenous and effort a continuous variable. Wage level, monitoring intensity and consequently the desired enforceable effort level are jointly determined by the maximization problem of the firm. As a result, monitoring and pay should be complements. In our experiment, between and within treatment variation is qualitatively in line with the normative predictions of the model under standard assumptions. Yet, we also find evidence for reciprocal behavior. Our data analysis shows, however, that it does not pay for the employer to solely rely on the reciprocity of employees
