Subjective Performance Evaluations and Reciprocity in Principal–Agent Relations

We conduct a laboratory experiment with agents working on, and principals benefiting from, a real effort task in which the agents' performance can only be evaluated subjectively. Principals give subjective performance feedback to agents, and agents have an opportunity to sanction principals. In contrast to existing models of reciprocity, we find that agents tend to sanction whenever the feedback of principals is below their subjective self‐evaluations even if agents' pay‐offs are independent of it. In turn, principals provide more positive feedback (relative to their actual performance assessment of the agent) if this does not affect their pay‐off.     

Agency in a market setting

This paper examines a market in which a continuum of principals and agents interact in a game. Principals offer contracts while agents decide on sets of acceptable contracts. A mechanism from a class satisfying efficiency, unbiasedness, and continuity properties then matches principals and agents. With risk neutral agents, when the contribution of principals and agents to the total gains from trade in a pairing are additively separable, the equilibria of the game coincide with the competitive equilibria for the market. In particular, all contracts used in Nash equilibrium induce first-best effort levels. Both principals and agents have exogenous opportunities outside this market. In equilibrium, agents have endogenously determined outside opportunities available from employment by another principal, and this may be the binding participation constraint in a principal-agent pairing. The results are extended to special non-separable cases and to the case of identical risk averse agents.We are grateful to seminar participants at Indiana University, the University of Kentucky, and Vanderbilt University for comments on earlier versions of this work. Referees' comments led us to generalize the model and to more clearly specify the point of the paper.     

Incentives and teacher effort

Few would contest that teachers are a very important determinant of how much students learn in school, and how to improve teacher performance has been the focus of lively policy debate in both rich and poor countries. This paper examines how teacher incentives, both pecuniary and non‐pecuniary, correlate with teacher effort. Using school survey data from Lao PDR, we estimate measures of teacher effort, including the number of hours that teachers spend preparing for classes and teacher provision of private tutoring outside of class hours, which are not the typical measures used in previous research. Estimation results fit well under the standard labour supply framework and indicate that greater teacher effort is associated with non‐pecuniary incentives such as more teacher autonomy over teaching materials and monitoring as measured by the existence of an active parent – teacher association and the ability of school principals to dismiss teachers. Methodologically, this paper provides a detailed derivation of a simultaneous OLS‐probit model with school random effects that can jointly estimate teacher work hours and tutoring provision.     

Cooperative Outcomes through Noncooperative Games

This paper shows the equivalence between the stable solution set of any cooperative game in characteristic form (G1) and the subgame perfect Nash equilibria in pure strategies of a certain noncooperative game (G2). Players of G1 are named "agents." G2 is played by different players ("principals") who compete in wages to attract agents. The equivalence result holds when there are enough principals (if the game is superadditive, two principals suffice). Finally, another related cooperative game (G3) is constructed with both principals and agents as players. For G2 and G3 the same result is then proven, for any number of principals.

Financing enterprise development in sub-Saharan Africa

This paper examines some critical gaps in the financial infrastructurein sub-Saharan Africa, which have contributed to the poor performanceof productive investment by private agents. It first analysesthe performance of financial systems, encompassing both formaland informal financial sectors, in relation to the changingpolicy environment, and key features of the financial marketstructure. It then identifies those gaps in financial servicesthat have been particularly detrimental to private investment,enterprise growth and transformation. Finally, the paper considerspolicy implications drawn from East Asian experiences with respectto financial policies, institutional arrangements and marketintegration measures for financing enterprise development.     

Information sharing between vertical hierarchies

When do principals independently choose to share the information obtained from their privately informed agents? Information sharing affects contracting within competing organizations and induces agentsʼ strategies to be correlated through the distortions imposed by principals to obtain information. We show that the incentives to share information depend on the nature of upstream externalities between principals and the correlation of agentsʼ information. With small externalities, principals share information when externalities and correlation have opposite signs, and do not share information when externalities and correlation have the same sign. In this second case, principals face a prisonersʼ dilemma since they obtain higher profits by sharing information.     

Negotiation and take it or leave it in common agency

This paper contrasts models of common agency in which principals compete in incentive contracts (that is, they make take it or leave it offers) with models where principals offer agents menus of incentive contracts from which the final contract is negotiated. It is shown that pure strategy equilibria in incentive contracts are robust to the possibility that principals might offer menus. In addition, a no-externalities condition is given such that any pure strategy equilibrium allocation with menus can be supported with competition in incentive contracts. The no-externalities condition is restrictive, but it is shown that it applies in most well-known common agency problems, including, for example, the Bertrand pricing problem.     

How important are school principals in the production of student achievement?

As school leaders, principals can influence student achievement in a number of ways, such as hiring and firing of teachers, monitoring instruction and maintaining student discipline, among many others. We measure the effect of individual principals on gains in math and reading achievement between grades 4 and 7 using a value‐added framework. We estimate that a one standard deviation improvement in principal quality can boost student performance by 0.289 to 0.408 standard deviations in reading and math, while the principal at the 75th percentile improves scores by 0.170 to 0.193 relative to the median principal. Our results imply that isolating the most effective principals and allocating them accordingly between schools can have a significant positive effect on reducing achievement gaps.     

Monitoring a common agent: Implications for financial contracting

Multiple principals want to obtain income from a privately informed agent and design their contracts non-cooperatively. The degree of coordination between principals shapes the contracts and affects the amount of monitoring. Equity-like contracts and excessive monitoring emerge when principals coordinate or verify each other's monitoring efforts. When this is not possible, free riding weakens monitoring incentives, so that flat payments, debt-like contracts, and very low levels of monitoring appear. Free riding may be so strong to induce even less monitoring than if the principals cooperated with each other; that is, non-cooperative monitoring does not necessarily lead to excessive monitoring.     

Delegation and Threat in Bargaining

Two principals (“nations”) appoint one agent each to bargain over the provision of a public good. Two institutional set-ups are studied, each with a different level of authority given to the agents. Here authority means the right to decide the own side's provision if negotiations break down. In equilibrium the principals choose agents with preferences differing from their own. The low-authority equilibrium Pareto dominates (with regard to the principals) the case of the principals deciding on the provisions simultaneously (autarchy). The high-authority equilibrium is Pareto dominated by the low-authority equilibrium and it may even be dominated by autarchy.Journal of Economic LiteratureClassification Numbers: C71, and C72.     

Bargaining Through Agents: An Experimental Study of Delegation and Commitment

While face-to-face bargaining has proven itself to be extremely efficient in the laboratory, it appears to break down often in the real world. This discrepancy, we assert, is explained by the fact that in the real world face-to-face bargaining is usually conducted not between principals but between the agents of principals. We find a substantial increase in inefficiency when bargaining is conducted through agents rather than through principals and offer an explanation for this rise in inefficiency. As such, this paper helps to shed light on the growing literature on delegation, commitment, and preference distortion games. Journal of Economic Literature Classification Numbers: C78, C92.

Pricing Monitoring Uncertainty in Climate Policy

This article assesses the environmental and economic efficiency of three different approaches to treat monitoring uncertainty in climate policy, namely prescribing uncertainty, setting minimum certainty thresholds and pricing uncertainty through a discount. Our model of the behavior of profit-maximizing agents demonstrates that under the simplest set of assumptions the regulator has no interest in reducing monitoring uncertainty. However, in the presence of information asymmetry, monitoring uncertainty may hamper the economic and environmental performance of climate policy due to adverse selection. In a mandatory policy, prescribing a reasonable level of uncertainty is preferable if the regulator has enough information to determine this level. For voluntary mechanisms, such as carbon offsets, allowing agents to set their own monitoring uncertainty below a maximum threshold or discounting carbon revenues in proportion to monitoring uncertainty are the best approaches for the regulator to mitigate the negative effects of information asymmetry. These conclusions are much more pronounced when agents do not accrue revenues from their mitigation action, other than carbon. Our analysis of monitoring uncertainty under information asymmetry, which results in heterogeneity in the agents’ benefits from abatement, generalizes the classical trade-off between production efficiency and information rents.

Forms of Opportunism Between Principals and Agents

The purpose of the paper is to discuss the development of the theoretical approach to a rating of the opportunism between the principals and agents within the framework of the neo-institutional theory. The matrix of the opportunistic forms between the principals and agents designed. On the basis of the carried out experimental research of firms of the Ural region of Russia, such opportunistic forms of the agents such as flubbing, negligence, and malversation were investigated. The experimental dependences of an opportunistic level of the agents from a level of wages, level of non-financial stimulus, effectiveness of punishment, share of creative element of labor, and degree of labor specificity are defined.

Does monitoring decrease work effort?: The complementarity between agency and crowding-out theories

Agency theory assumes that tighter monitoring by the principal should motivate agents to increase their effort, whereas the “crowding-out” literature suggests that the opposite may occur. These two assertions are not necessarily contradictory provided that the nature of the employment relationship is taken into account [Frey, B., 1993. Does monitoring increase work effort? The rivalry between trust and loyalty. Econ. Inquiry 31, 663–670]. Results from controlled laboratory experiments show that many principals engage in costly monitoring, and most agents react to the disciplining effect of monitoring by increasing effort. However, we also find some evidence that effort is crowded out when monitoring is above a certain threshold. We identify that both interpersonal principal–agent links and concerns for the distribution of output payoff are important for the emergence of this crowding-out effect.     

Imperfect information, Bayesian learning, and capital accumulation

This paper examines the consequences of informational imperfections for economic growth in an overlapping generations model in which agents learn the technological parameters in a Bayesian fashion. Under mild sufficient conditions, beliefs converge to the true value of the technological parameters. Nevertheless, even short-lived informational imperfections could have lasting effects, as they alter the long-run equilibrium levels of the capital stock. Therefore, learning dynamics may explain some of the observed differences in the performance of countries with otherwise similar economic characteristics.     

On the optimal social contract: Agency costs of self-government

In a typical study of political economy, citizens are regarded as the principals, and government as the agent. In contrast, classical theorists of democracy such as Jean-Jacques Rousseau and James Madison were deeply interested in the dual nature of people; they are the principals (citizens sharing the sovereign power) and, at the same time, the agents (subjects under the laws). Government, in their framework, is an intermediate body which helps people solve their self-control problem. Equipped with tools of modern economics, this paper explores the classical problem to see how economic development and political institutionalization relate to the structure of government and the quality of public sector. In particular, I consider repeated games with a large population and incomplete information, in which players decide whether to sacrifice private consumption to provide public goods. Because both people and the executive of the public projects are subject to moral hazard, the people spend resources to monitor the executive and the people themselves. The optimal self-enforcing contract, which can be interpreted as an efficiency upper bound of political systems, is characterized. An analysis of the contract shows that as a country gets more economically developed and politically institutionalized, the agency problem on the people’s side becomes negligible and that poor economic performance of a country might prevent the citizens from establishing a more efficient public sector.     

Coordination and discrimination in contracting with externalities: divide and conquer?

The paper studies bilateral contracting between N agents and one principal, whose trade with each agent generates externalities on other agents. It examines the effects of prohibiting the principal from (i) coordinating agents on her preferred equilibrium, and (ii) making different contracts available to different agents. These effects depend on whether an agent is more or less eager to trade when others trade more. The prohibitions reduce the aggregate trade in the former case, and have little or no effect in the latter case. The inefficiencies under different contracting regimes are linked to the sign of the relevant externalities, and are shown to be typically reduced by both prohibitions.     

Status,Risk-Taking and Intertemporal Substitution in an Endogenous Growth Model

This paper examines intertemporal risk-taking in a stochastically growing economy with externalities in human capital accumulation where agents have preferences for social status. In order to isolate the effects of status concerns on long-run expected growth, the analysis is embedded in a non-expected utility setting, which disentangles the effects from risk aversion and intertemporal substitution. We examine the interaction between status desire and risk, risk aversion and intertemporal substitution. The externalities generated by the status game are able to correct the allocative distortions from the knowledge spillovers.Acknowledgement The author would like to thank an anonymous referee for his valuable comments.
