TL;DR: In this article, the authors study moral hazard with many agents and focus on two features that are novel in a multiagent setting: free riding and competition, and show that competition among agents (due to relative evaluations) has merit solely as a device to extract information optimally.
Abstract: This article studies moral hazard with many agents. The focus is on two features that are novel in a multiagent setting: free riding and competition. The free-rider problem implies a new role for the principal: administering incentive schemes that do not balance the budget. This new role is essential for controlling incentives and suggests that firms in which ownership and labor are partly separated will have an advantage over partnerships in which output is distributed among agents. A new characterization of informative (hence valuable) monitoring is derived and applied to analyze the value of relative performance evaluation. It is shown that competition among agents (due to relative evaluations) has merit solely as a device to extract information optimally. Competition per se is worthless. The role of aggregate measures in relative performance evaluation is also explored, and the implications for investment rules are discussed.

TL;DR: In this paper, the authors developed a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders, and presented a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary.
Abstract: This paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders. It presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary. Diversification within an intermediary serves to reduce these costs, even in a risk neutral economy. The paper presents some more general analysis of the effect of diversification on resolving incentive problems. In the environment assumed in the model, debt contracts with costly bankruptcy are shown to be optimal. The analysis has implications for the portfolio structure and capital structure of intermediaries.

TL;DR: In this article, a principal-agent model that can explain why employment is sometimes superior to independent contracting even when there are no productive advantages to specific physical or human capital and no financial market imperfections to limit the agent's borrowings is presented.
Abstract: Introduction In the standard economic treatment of the principal–agent problem, compensation systems serve the dual function of allocating risks and rewarding productive work. A tension between these two functions arises when the agent is risk averse, for providing the agent with effective work incentives often forces him to bear unwanted risk. Existing formal models that have analyzed this tension, however, have produced only limited results. It remains a puzzle for this theory that employment contracts so often specify fixed wages and more generally that incentives within firms appear to be so muted, especially compared to those of the market. Also, the models have remained too intractable to effectively address broader organizational issues such as asset ownership, job design, and allocation of authority. In this article, we will analyze a principal–agent model that (i) can account for paying fixed wages even when good, objective output measures are available and agents are highly responsive to incentive pay; (ii) can make recommendations and predictions about ownership patterns even when contracts can take full account of all observable variables and court enforcement is perfect; (iii) can explain why employment is sometimes superior to independent contracting even when there are no productive advantages to specific physical or human capital and no financial market imperfections to limit the agent's borrowings; (iv) can explain bureaucratic constraints; and (v) can shed light on how tasks get allocated to different jobs.

TL;DR: For example, the authors estimates of the pay-performance relation (including pay, options, stockholdings, and dismissal) for chief executive officers indicate that CEO wealth changes $3.25 for every $1,000 change in shareholder wealth.
Abstract: Our estimates of the pay-performance relation (including pay, options, stockholdings, and dismissal) for chief executive officers indicate that CEO wealth changes $3.25 for every $1,000 change in shareholder wealth. Although the incentives generated by stock ownership are large relative to pay and dismissal incentives, most CEOs hold trivial fractions of their firms' stock, and ownership levels have declined over the past 50 years. We hypothesize that public and private political forces impose constraints that reduce the pay-performance sensitivity. Declines in both the pay-performance relation and the level of CEO pay since the 1930s are consistent with this hypothesis.

TL;DR: In this article, a review of existing work on the provision of incentives for workers is presented, and the authors evaluate this literature in the light of a growing empirical literature on compensation from two perspectives: first, an underlying assumption of this literature is that individuals respond to contracts that reward performance.
Abstract: I NCENTIVES ARE the essence of economics. Despite many wide-ranging claims about their supposed importance, there has been little empirical assessment of incentive provision for workers. The purpose of this paper is to critically overview existing work on the provision of incentives. Since the interests of workers and their employers are not always aligned, a large theoretical literature has emphasized how firms design compensation contracts to induce employees to operate in the firm's interest. This literature has reached into many areas of compensation and has pointed to a multitude of different mechanisms that can be used to induce workers to act in the interests of their employers. These include piece rates, options, discretionary bonuses, promotions, profit sharing, efficiency wages, deferred compensation, and so on. My objective here is to evaluate this literature in the light of a growing empirical literature on compensation. Where possible, I will address the literature from two perspectives. First, an underlying assumption of this literature is that individuals respond to contracts that reward performance. Accordingly, I consider whether agents behave in this way, and whether these responses are always in the firm's interest. Second, I address whether firms write contracts with these responses in mind. In other words, do contracts look like the predictions of the theory? Incentives are provided to workers

TL;DR: The canonical agency problem can be posed as follows as discussed by the authors : the agent may choose an act, aCA, a feasible action space, and the random payoff from this act, w(a, 0), will depend on the random state of nature O(EQ the state space set), unknown to the agent when a is chosen.
Abstract: The relationship of agency is one of the oldest and commonest codified modes of social interaction. We will say that an agency relationship has arisen between two (or more) parties when one, designated as the agent, acts for, on behalf of, or as representative for the other, designated the principal, in a particular domain of decision problems. Examples of agency are universal. Essentially all contractural arrangements, as between employer and employee or the state and the governed, for example, contain important elements of agency. In addition, without explicitly studying the agency relationship, much of the economic literature on problems of moral hazard (see K. J. Arrow) is concerned with problems raised by agency. In a general equilibrium context the study of information flows (see J. Marschak and R. Radner) or of financial intermediaries in monetary models is also an example of agency theory. The canonical agency problem can be posed as follows. Assume that both the agent and the principal possess state independent von Neumann-Morgenstern utility functions, G(.) and U(.) respectively, and that they act so as to maximize their expected utility. The problems of agency are really most interesting when seen as involving choice under uncertainty and this is the view we will adopt. The agent may choose an act, aCA, a feasible action space, and the random payoff from this act, w(a, 0), will depend on the random state of nature O(EQ the state space set), unknown to the agent when a is chosen. By assumption the agent and the principal have agreed upon a fee schedule f to be paid to the agent for his services. T he fee, f, is generally a function of both the state of the world, 0, and the action, a, but we will assume that the action can influence the parties and, hence, the fee only through its impact on the payoff. T his permits us to write,

TL;DR: The concept of perfect equilibrium point has been introduced in order to exclude the possibility that disequilibrium behavior is prescribed on unreached subgames [Selten 1965 and 1973]. Unfortunately this definition of perfectness does not remove all difficulties which may arise with respect to unreached parts of the game.
Abstract: The concept of a perfect equilibrium point has been introduced in order to exclude the possibility that disequilibrium behavior is prescribed on unreached subgames [Selten 1965 and 1973]. Unfortunately this definition of perfectness does not remove all difficulties which may arise with respect to unreached parts of the game. It is necessary to reexamine the problem of defining a satisfactory non-cooperative equilibrium concept for games in extensive form. Therefore a new concept of a perfect equilibrium point will be introduced in this paper2).

TL;DR: In this article, a notion of "favorableness" of news is introduced, characterized, and applied to four simple models: the arrival of good news about a firm's prospects always causes its share price to rise, more favorable evidence about an agent's effort leads the principal to pay a larger bonus, buyers expect that any product information withheld by a salesman is unfavorable to his product, and bidders figure that low bids by their competitors signal a low value for the object being sold.
Abstract: This is an article about modeling methods in information economics. A notion of "favorableness" of news is introduced, characterized, and applied to four simple models. In the equilibria of these models, (1) the arrival of good news about a firm's prospects always causes its share price to rise, (2) more favorable evidence about an agent's effort leads the principal to pay a larger bonus, (3) buyers expect that any product information withheld by a salesman is unfavorable to his product, and (4) bidders figure that low bids by their competitors signal a low value for the object being sold.
